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 work belong to the protection scope of the present invention.

Referring to fig. 1-4, the application discloses a durable firing pin, including firing pin 1, needle file 2 and fixed group 3, firing pin 1 includes two percussion portions 11 and sets up connecting portion 12 between two percussion portions 11, and connecting portion 12 is used for connecting two percussion portions 11, is equipped with the holding tank 21 that is used for accomodating percussion portion 11 on needle file 2, and fixed group 3 installs at the opening part of holding tank 21 to with connecting portion 12 fixed connection.

One side of needle file 2 near the opening part of holding tank 21 is equipped with the through-hole 22 that communicates with holding tank 21, and fixed group 3 includes bobble 31 and sleeve 32, and bobble 31 movably installs in through-hole 22 to can with install the connecting portion 12 butt in holding tank 21, sleeve 32 cover is established on needle file 2, and sleeve 32 inside wall and bobble 31 butt.

Specifically, the 11 symmetry settings of the percussion part of firing pin 1 two, connecting portion 12 is the columnar structure, and be equipped with on it can with bobble 31 sliding connection's spout, when percussion part 11 and connecting portion 12 card of firing pin 1 one side are gone into holding tank 21, spout on the connecting portion 12 just contacts with bobble 31, after holding tank 21 is gone into to the card completely, because be equipped with the internal thread in the sleeve 32, be equipped with the external screw thread of being connected with sleeve 32 internal thread fit on the needle file 2, just screw through sleeve 32, at this moment, one side that the spout was kept away from to bobble 31 and sleeve 32's inside wall butt, and under the effort of sleeve 32's inside wall, make bobble 31 constantly exert pressure to connecting portion 12, reach the condition that restriction connecting portion 12 removed, and then form firing pin 1 and fix on needle file 2.

Further, the inner side wall of the sleeve 32 is obliquely arranged, and the inclined cylinder diameter is gradually reduced from the inner thread close to the sleeve 32 to the inner part.

Referring to fig. 1-4, when the sleeve 32 is mounted on the needle base 2, the inner wall of the sleeve 32 abuts against the small ball 31, wherein, due to the inclined inner wall, the small ball 32 is continuously extruded in the process of continuously screwing the sleeve 32 until the small ball is clamped between the sleeve wall and the sliding groove, so that the connecting part can be tightly mounted in the holding groove 21, and the firing part 11 of the firing pin in the holding cavity 21 of the needle base 2 is prevented from being separated from the holding groove by external impact when in use.

Further, the end of the sleeve 32 away from the internal thread is provided with a ring abutting block 33, and when the sleeve 32 is mounted on the needle base 2, the ring abutting block 33 abuts against one side of the connecting portion arranged in the accommodating groove 21.

Specifically, in order to enhance the stability of the striker 1 mounted on the needle base 2, after the sleeve 32 is sleeved on the needle base 2, the ring abutting block 33 abuts against one side of the connecting portion close to the opening of the accommodating cavity, so that when the durable striker is limited to be impacted, the striker arranged in the accommodating cavity is pushed out of the outside by a reaction force, and the use is affected.

Further, a protection pad 4 is included, and the protection pad 4 is installed in the receiving groove 21 to protect the end of the firing part 11 disposed in the receiving groove 21.

It should be noted that while the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
