[0002] The anti-riot pistol is a special gun mainly used for maintaining social public order, and the safety spring and the trigger return spring need to be maintained frequently to maintain the use performance. The safety spring is used to avoid accidental firing of the gun, and the trigger return spring is used for the accuracy and continuity of shooting, both of which are particularly important for the normal use of the gun. In the process of disassembling the safety spring at the present stage, a screwdriver is usually used to press against the internal gap of the spring to disassemble it. In the process of operation, the safety spring is deformed due to uneven force, and cannot be used continuously. Moreover, the surface hardness of the screwdriver is high, which can easily scratch the inner surface of the gun body, and may cause the gun to malfunction. For the trigger return spring, the screwdriver needs to be inserted into the tail end of the trigger return spring and lifted upwards, which may cause the spring to pop out. At the same time, the screwdriver does not have enough area to compress radially during reinstallation, which is inconvenient to operate. Moreover, the proficiency of this operation largely determines the speed of disassembly. If the operation is not skilled, it will take a long time to operate, affecting the maintenance progress.

[0024] The utility model will be further explained in connection with the drawings and examples, but not as the basis for the limitation of the utility model.

[0025] Example: multifunctional disassembler, such as attached Figure 1 and attached Figure 2As shown, including a diameter of 5mm long 70.7mm stainless steel handle 1, handle 1 both ends are respectively processed with hook claw part 2 and the piece part 3;The hook claw part 2 includes symmetrically processing 4.1mm long clamp block 4 in the end of handle 1, clamp block 4 has 3.5mm clamping gap 12 between them;The end of clamp block 4 is processed with hook claw 5, the length of hook claw is 2.2mm, the width is 1.5mm, the radial distance of its end and handle axis is 1.8mm, the back of hook claw 5 and the surface of corresponding clamp block 4 are processed with 0.5mm high push piece step 6;The piece part 3 includes 3mm long first piece 7 and 6mm long second piece 8, which are arranged above and below and are processed in the end of handle 1, the first piece and the second piece are parallel, the first piece 7 and the second piece 8 have 2mm wide engagement gap 9 between them;The bending part of hook claw 5 has a circular arc transition, the inside arc surface radius of the bending part is 1mm, which avoids scratching the surface of the gun part;The surface of handle 1 is processed with first inclined surface 10 corresponding to the front and back of hook claw, the upper surface of push piece step 6 is connected with first inclined surface 10, the angle between the first inclined surface corresponding to the back of hook claw and the handle axis is 3°, and the angle between the first inclined surface corresponding to the front of hook claw and the handle axis is 5°, which is used to shrink the volume of one side of hook claw part to facilitate the insertion into the small internal space of the gun;The inner end edge corner of clamping gap 12 has a radius of 1mm circular arc transition, which avoids scratching the surface of the gun part;The cross section of hook claw 5 is quadrilateral, and the edge corner of the end of hook claw 5 has a round corner transition, the quadrilateral shape can generate sufficient torsional force after being embedded in the slot, and the round corner transition is used to reduce scratching;The front and back of first piece 7 and second piece 8 are processed with second inclined surface 11, the angle between second inclined surface and handle axis is 5°, which is used to shrink the volume of first piece and second piece to facilitate the insertion into the small internal space of the gun;The edge corner of the end of first piece 7 and second piece 8 has a chamfer transition, which avoids scratching the surface of the gun part;The inner end edge corner of engagement gap 9 has a radius of 1mm circular arc transition.

[0026] Working principle: when the safety spring needs to be disassembled, as shown in the accompanying Figure 3 The two hook claws 5 of hook claw part 2 are precisely embedded in the groove of safety spring, because the safety spring is installed tightly in the gun body, the traditional screwdriver disassembly method is easy to cause its deformation, and the edge corner of the hook claw of the embodiment can effectively avoid scratching the surface of the safety spring and the gun body during embedding in the groove;The operator holds the handle 1 and pulls it outwards, uses the tight fit between hook claw 5 and safety spring groove, uniformly applies force, overcomes the friction between safety spring and gun body, and realizes the smooth disassembly of safety spring;Compared with the method of traditional screwdriver against the internal notch of the spring, the disassembly method greatly reduces the risk of safety spring deformation and ensures the reusability of safety spring.

[0027] In the installation of the safety spring, the operation steps are as shown in the accompanying Figure 4 First, place the uninstalled safety spring in the gun body groove at the safety shaft position, then press the safety spring with the back of the hook claw 5, the back of the hook claw 5 is resisted by the push piece step 6 arranged between the surface of the clamp block 4 and the rear end of the safety spring, the operator pushes inward through the handle 1, and the safety spring gradually moves inward during the pushing process until it is embedded in the safety shaft and concentric with it, completing the installation; this installation method can ensure that the safety spring is accurately installed in place, improving the installation precision and efficiency.

[0028] For the disassembly of the trigger return spring, as shown in the accompanying Figure 5 Insert one of the hook claws 5 into the trigger return spring and make it protrude from the spring, when the trigger return spring is pulled out, the clamping gap 12 can prevent it from accidentally popping out, ensuring the safety of the operator; at the same time, the corner of the end of the hook claw 5 is rounded, which reduces the scratching of the trigger return spring during insertion and pulling out, avoids damage to it, and ensures that the performance of the trigger return spring is not affected.

[0029] When installing the trigger return spring, as shown in the accompanying Figure 6 and the accompanying Figure 7 First, insert the uninstalled trigger return spring into the spring seat, then insert the first tab 7 between the springs, and use the engagement gap 9 between the first tab 7 and the second tab 8 to position the trigger return spring in the correct installation position; at this time, the second tab 8 is against the tail end of the trigger return spring, the operator applies force to the handle 1, and slowly pushes the trigger return spring into the gun body; after completing the pushing, press down the handle 1, press down the spring seat in the reset outward state through the engagement gap 9, and make the trigger return spring completely installed in place, this installation method improves the installation accuracy and convenience compared with the traditional screwdriver operation, and reduces the installation failure caused by improper operation.

[0030] As shown in the accompanying Figure 8 The second tab 8 in the form of a sheet also has the function of a flathead screwdriver, during the maintenance of firearms, there may be situations that require disassembly and assembly of screws, the width and shape of the second tab 8 are designed to be compatible with common flat screw grooves, when in use, insert the second tab 8 into the screw groove, rotate the handle 1, use the friction between the second tab 8 and the screw groove to tighten or loosen the screw, further expand the application scenarios of the embodiment, reduce the number of tools needed during the maintenance of firearms, and improve work efficiency.

[0031] The above embodiment only expresses the implementation mode of the utility model, and the description is relatively specific and detailed, but cannot be understood as the limitation of the utility model patent range, and in the embodiment, up, down, left, right, front and back only represent relative positions and do not represent absolute positions.
