Due to the large spring force of the firing pin spring, it is difficult to disassemble and assemble, and the assembly efficiency is low. At the same time, during the troubleshooting process, if the firing pin is in the hang-up state, there is a safety hazard. The firing pin must be released before troubleshooting, and the primer will not be fired during the release process. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a tool and method for releasing the firing pin and disassembling the firing pin spring. When disassembling the firing pin spring, the difficulty is smaller and the efficiency is higher. When the firing pin is in the hanging state, the present invention has the function of releasing the firing pin, and at the same time, the primer will not be fired during the release process.

[0004] The object of the present invention is achieved in that:

The diameter of the large end of the tool is smaller than the diameter of the firing pin hole and larger than the inner diameter of the firing pin spring. The large end of the tool is used to extend into the firing pin hole to compress the firing pin spring. A U-shaped groove is provided at the end of the large end of the tool. The width and depth of the U-shaped groove are both larger than the diameter of the needle spring pin. The U-shaped groove is used to make way for the firing pin spring pin. A clamping groove is provided at the portion adjacent to the large end of the tool and the small end of the tool. The width of the clamping groove is larger than the diameter of the firing pin spring pin. The distance between the bottom of the clamping groove and the center line of the tool is smaller than the inner diameter of the firing pin spring. The clamping groove is for inserting the firing pin spring pin.

[0006] The diameter of the small end of the tool is smaller than the inner diameter of the firing pin spring, and the length of the small end of the tool is smaller than the distance between the bottom of the firing pin hole and the needle spring pin. It is used to connect with the firing pin spring. The diameter of the small end of the tool is smaller than the width of the firing pin waist groove, and is used to insert into the firing pin waist groove and rotate the firing pin.

[0007] Preferably, the large end of the tool has two symmetrically arranged slots to form a flat square.

[0008] A method for releasing a firing pin and disassembling a firing pin spring, comprising a tool for releasing a firing pin and disassembling a firing pin spring,

[0009] To remove the firing pin spring: Use the large end of the tool to compress the firing pin spring until the firing pin spring and the firing pin spring pin are released, then remove the firing pin spring and then remove the firing pin spring.

[0010] Method for assembling the firing pin spring: Use the small end of the tool to penetrate the firing pin spring, and then put it into the firing pin hole. Use the tool to compress the firing pin spring so that the firing pin waist groove is opposite to the tool's slot. Then, push the entry end of the firing pin spring pin against the bottom of the tool's slot. At this time, pull out the tool so that the firing pin spring contacts the firing pin spring pin. The firing pin spring is assembled in place.

[0011] Method to release the firing pin: insert the small end of the tool into the firing pin waist groove, release the firing pin by rotating it, and the firing pin cannot strike at the same time.

[0012] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0013] The large end of the tool can be placed in the firing pin hole, and the small end of the tool can be placed in the firing pin spring hole, and the junction of the large end and the small end is a step, which can limit the firing pin spring. The U-shaped groove at the large end of the tool can give way to the firing pin spring pin, and the plane of the slot is lower than the outer diameter of the firing pin spring. When disassembling and assembling the firing pin spring, the difficulty is lower and the efficiency is high. When the firing pin is in the hanging state, the present invention has the function of releasing the firing pin, and the primer will not be fired during the release process.

DETAILED DESCRIPTION

[0019] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. The method of use is as follows:

[0020] A tool for releasing a firing pin and disassembling a firing pin spring. The tool is in the shape of a stepped shaft. The diameter of a large end 11 of the tool is smaller than the diameter of the firing pin hole and larger than the inner diameter of the firing pin spring 02. The large end 11 of the tool is used to extend into the firing pin hole to compress the firing pin spring 02. A U-shaped groove 111 is provided at the end of the large end 11 of the tool. The width and depth of the U-shaped groove 111 are both larger than the diameter of the needle spring pin 03. The U-shaped groove 111 is used to make way for the firing pin spring pin 03. A slot 112 is provided at the portion adjacent to the large end 11 and the small end 12 of the tool. The width of the slot 112 is greater than the diameter of the firing pin spring pin 03, and the distance between the bottom of the slot 112 and the centerline of the tool is smaller than the inner diameter of the firing pin spring 02, and the slot 112 is for inserting the firing pin spring pin 03; the diameter of the small end 12 of the tool is smaller than the inner diameter of the firing pin spring 02, and the length of the small end 12 of the tool is smaller than the distance between the bottom of the firing pin hole and the needle spring pin, and is used to be socketed with the firing pin spring 02, and the diameter of the small end 12 of the tool is smaller than the width of the firing pin waist groove 011, and is used to insert into the firing pin waist groove 011 to rotate the firing pin 01.
