Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as up, down, left, right, front, back, 8230; \8230;) are provided in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indications are correspondingly changed.
The utility model provides a nail firing pin is prevented blocking.
In the embodiment, referring to fig. 1-4, the anti-sticking striker includes a striker main body 1, and a yield notch 2 is formed at the top of the striker main body.
Among the above-mentioned technical scheme, set up the breach of stepping down through the top at the firing pin main part, provide the clearance of stepping down for the nail that links to each other to can avoid the firing pin to appear striking the problem of adjacent nail when striking the nail, improve the job stabilization nature, the safety in utilization and the life of penetrating the nail instrument.
Although the improved structure is small, the improved structure is ingenious in design, the problem that the industry can be difficult to solve and find all the time can be overcome, the comprehensive performance of the nail shooting tool is greatly improved, the requirement of the nail shooting tool on the quality of the strip nails is reduced, and the nail shooting tool is adaptive to the strip nails and has stronger capacity.
Specifically, the abdicating notch is of a water-drop-shaped structure.
More specifically, the abdicating notch is of a structure smaller than 1/2 of water drops, so that the rigidity of the firing pin can be ensured, and the nail is prevented from being clamped into the abdicating notch.
Specifically, the firing pin body comprises a ejector rod section 3, a sawtooth section 4 and a connecting section 5, wherein one side of the sawtooth section is provided with a lifting tooth 6, the other side of the sawtooth section is provided with a locking tooth 7, one side of the locking tooth, which is located on the ejector rod section, is a locking vertical surface 8, and one side, which is far away from the ejector rod section, is an inclined surface 9.
Among the above-mentioned technical scheme, through setting up promotion tooth and lock tooth in firing pin body both sides, the promotion return of firing pin is realized with the gear cooperation on the hoist mechanism to the promotion tooth, and the lock tooth can prevent the accident of firing pin from beating with the pawl cooperation, improves the safety in utilization.
