Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Priority Acknowledgment is made of applicant's claim for foreign priority based on an application filed in China on 06-21-2024. It is noted, however, that applicant has not filed a certified copy of the CN202421434921.4 application as required by 37 CFR 1.55. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(5) because they do not include the following reference sign(s) mentioned in the description: 131. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claims 1-7 are objected to for being replete with minor informalities, the following changes overcome all such informalities: Claim 1. A detachable rotating structure, comprising: a first part (100) and [[the]] a second part (111), [[the]] an end of the first part (100) is rotatably connected via a rotating shaft (113) to an end of the second part (111), the (130) for being received in the grooves (115), the stopper (130) is elastically clamped in the grooves (115) along the axial direction of the rotating shaft (113), the stopper (130) has an abutting surface (116) facing the grooves (115), the abutting surface (116) s against s (115) to limit the rotation of the first part (100) and the second part (111); [[A]] and a linkage block (122) is provided at the rotating part of the first part (100) and the second part (111) for pushing the stopper (130) along the length direction of the second part (111). Claim 2. [[A]] The detachable rotating structure according to claim 1, wherein: [[A]] a housing (112) is provided at the end of the second part (111), the end of the first part (100) has a moving ring (114) rotatably connected to the housing (112), the grooves (115) [[is]] are provided on [[the]] a side ring surface of the moving ring (114), [[the]] an outer [[side]] edge of the moving ring (114) has a circumferential avoidance groove (123), a linkage ring (120) for abutting against a side an outer [[wall]] edge of the linkage ring (120), and a protrusion (121) received in the avoidance groove (123) is also provided on [[the]] a side ring surface of the linkage ring (120), the protrusion (121) is [[used]] configured to abut against the side wall of the avoidance groove (123), so that the linkage ring (120) rotates synchronously. Claim 3. [[A]] The detachable rotating structure according to claim 2, wherein: [[The]] the stopper comprises a limiting block (130) elastically sliding along the axial direction of the rotating shaft (113) at the end of the second part (111), a one-way convex tooth (131) arranged on [[the]] a side of the limiting block (130) adjacent the moving ring (114), and the linkage block (122) is [[used]] configured to abut against the limiting block (130). Claim 4. [[A]] The detachable rotating structure according to claim 3, wherein: [[The]] the end of the second part (111) has a first groove (133) for receiving the limiting block (130) therein in [[its]] the length direction of the second part, a first elastic member is arranged between [[the]] a bottom of the first groove (133) and the limiting block (130), and the housing (112) has a second elastic member connected to the limiting block (130) and biasing it into the grooves (115). Claim 5. [[A]] The detachable rotating structure according to claim 2, wherein: [[The]] the stopper comprises a limiting block (130) arranged at the end of the second part (111), and a one-way protrusion (142) elastically arranged on the limiting block (130) along the axial direction of the rotating shaft (113), and the one-way protrusion (142) has a guiding inclined surface (144) for contacting [[the]] an edge of the grooves (115) on one side along the rotating direction, and abutment surface (116) on another side. Claim 6. [[A]] The detachable rotating structure according to claim 5, wherein: [[The]] the one-way protrusion (142) is evenly distributed along the rotating direction Claim 7. [[A]] The detachable rotating structure according to claim 6, wherein: [[The]] an end of the grooves (115) facing outward in the radial direction is [[an]] open[[ing]]. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. In claim 1, lines 3-4, the phrase, “the rotating end of the first part (100) is uniformly provided with a plurality of grooves (115) along the rotating direction” is inaccurate. The first part 100 does not include the grooves 115, but rather a moving ring 114 includes the grooves 115, see Fig. 4. It appears the moving ring 114 must be claimed, see claim 2, lines 3-4 for accurate language. In claim 1, line 9, “the rotating part” lacks antecedent basis. It appears the applicant is attempting to reference a linkage ring 120 which includes the linkage block 122, see claim 2, lines 6-7 for accurate language. In claim 5, lines 2-4, the phrase “a one-way protrusion (142) elastically arranged on the limiting block (130) along the axial direction of the rotating shaft (113)” is inaccurate. The one-way protrusion 142 is arranged on the limiting block 130 along the rotating direction, see claim 6 for accurate language. Claims 2-4, 6, and 7 are also rejected under 35 U.S.C. 112(b) as they depend from a rejected claim. Allowable Subject Matter Claims 1-7 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The above corrections to overcome the claim objections are also required. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO-892.
