The gun body 21 is provided with a sleeve return spring 25 and a sleeve lock assembly for locking / unlocking the sleeve 24 in the second position. The sleeve return spring 25 deforms and stores energy when the sleeve 24 moves from the first position to the second position, thereby providing a driving force for driving the sleeve 24 to return from the second position to the first position. The sleeve 24 is provided with a lock portion 241 corresponding to the sleeve lock assembly. The sleeve lock assembly includes a sliding lock member 26. The gun body 21 is provided with an inner seat body 211 convexly inserted into the sleeve 24. The sliding lock member 26 is arranged on the inner seat body 211 along the transverse sliding of the sleeve 24. The sliding lock member 26 has a lock head 261 that locks / unlocks with the lock portion 241. The sliding lock member 26 has a lock head 261 along the sliding direction that is in a locked position (such as Figure 3 and Figure 6 As shown), and the lock head 261 is in an unlocking position that can be disengaged from the lock portion 241, the lock portion 241 is arranged on the inner wall of the sleeve 24, the sliding lock 26 is abutted against a lock spring 27, the lock spring 27 provides an elastic driving force for driving the sliding lock 26 to slide to the locked position, and the sliding lock 26 is connected to an unlocking key 28 for operating the sliding lock 26 to slide to the unlocking position. Pull the sleeve 24 backward (in the direction facing away from the exit end of the barrel as shown in the figure, direction a shown in the figure), the sleeve 24 moves from the first position to the second position, the sleeve 24 compresses the sleeve return spring 25, and the sliding lock 26 automatically locks the lock part 241 on the sleeve 24 under the drive of the lock spring 27, the sleeve 24 is locked in the second position, and the sleeve return spring 25 stores energy; through the unlocking key 28, the sliding lock 26 can be pushed to slide into the unlocking position, the lock head 261 disengages the lock part 241 to complete the unlocking, and the sleeve 24 automatically rebounds from the second position to the first position under the drive of the sleeve return spring 25, realizing the movable operation of the sleeve and increasing the playability of the lighter. The sliding lock and the lock part of the sleeve are built into the sleeve, which not only protects the lock structure and makes the outside of the gun body neat, but also the sliding lock adopts a sliding action, which has the advantages of stable and reliable action.

[0024] In order to further improve the operability, the sleeve can be unlocked by pulling the trigger at the same time, that is, the sleeve is automatically ejected from the second position to the first position by pulling the trigger. The trigger 22 is linked with a transmission member 29, which is slidably arranged on the gun body 21 along the length direction of the sleeve 24 (such as the direction of the Z axis in the figure). The transmission member 29 has a push portion 291, and the sliding lock 26 has a push matching portion 262.

[0025] In one embodiment of the present invention, the sliding lock 26 slides along the height direction of the inner seat 211 (the direction of the Y axis in the figure), and the inner seat 211 has a larger activity space in the height direction, which is convenient for the installation and arrangement of the sliding lock. The end of the sliding lock 26 opposite to the lock head 261 extends out of the bottom of the inner seat 211 and is formed with the push fitting portion 262. The transmission member 29 is slidably fitted at the bottom of the inner seat 211. A spring hole is provided at the bottom of the sliding lock 26. A spring support plate 212 corresponding to the position of the spring hole is provided below the inner seat 211. One end of the lock spring 27 is inserted into the spring hole and supported on the sliding lock 26, and the other end of the lock spring 27 is supported on the spring support plate 212. Therefore, in another embodiment of the present invention, the sliding lock 26 can also be slidably arranged along the width direction of the inner seat, but the space in the width direction of the inner seat is greatly limited, so it is preferred to arrange the sliding lock 26 along the height direction of the inner seat (the direction of the Y axis in the figure).

[0026] As an embodiment of the present invention, the trigger 22 is pivotally mounted on the gun body 21, and the piezoelectric device 13 is located on the side of the trigger 22 facing the exit of the gun barrel 23. The trigger 22 rotates to press the piezoelectric device 13, and the piezoelectric device is located close to the exit of the gun barrel, which is convenient for wiring of the piezoelectric device. As another common implementation method, the trigger can also be slidably arranged on the gun body, and therefore the piezoelectric device needs to be arranged at the rear position of the gun body, which is far away from the exit of the gun barrel and the firing head, and is not convenient for wiring. Under this design, a large space can be reserved at the rear of the gun body 21 for arranging the gas box 12, and the gas box 12 can be arranged on the side of the transmission member 29 away from the trigger 22, and the transmission member 29 drives the seesaw 14 to open and close the gas valve 121 of the gas box 12. It is convenient for the transmission member to drive the seesaw; a driving notch 292 is provided on the transmission member 29, and the seesaw 14 is inserted into the driving notch 292. When the transmission member slides, the seesaw is pushed to swing, thereby controlling the opening and closing of the gas valve. Of course, the gas box can also be placed at the position corresponding to the magazine on the gun body.

[0027] Furthermore, the trigger 22 has a lever 221, the transmission member 29 is provided with a push portion 293, the switch end of the piezoelectric device 13 abuts against the push portion 293 of the transmission member 29, the lever 221 of the trigger 22 abuts against the push portion 293, the gun body 21 is provided with a trigger limit column 213, the trigger limit column 213 is located on the side of the lever 221 facing away from the piezoelectric device 13, and the lever 221 of the trigger 22 cooperates with the trigger limit column 213 to stop. Figure 4 As shown, a positioning groove is provided on the push-moving part of the transmission member, and the switch end of the piezoelectric device 13 is positioned and inserted in the positioning groove, so as to realize a more reliable cooperation between the piezoelectric device and the push-moving part. The size between the control trigger limit column and the trigger lever is controlled, and the trigger is limited by the trigger limit column. In the free state, the switch end of the piezoelectric device 13 pushes the push-moving part 293, and the push-moving part 293 is against the lever 221 on the trigger 22, so as to avoid the shaking of the trigger. Under this design, the reset of the trigger and the transmission member can rely on the restoring force of the switch end of the piezoelectric device, which has the advantages of simple and compact structure; and the push-pushing linkage is realized by the contact, and a single lever can simultaneously achieve synchronous push-pushing of the transmission member and pressing of the piezoelectric device, which has a simple structure, convenient assembly and reliable operation. Of course, under the guidance of the utility model, the transmission member can independently design a spring to realize its reset, as well as the linkage cooperation between the transmission member and the trigger; the transmission member can adopt a bar-shaped hanging hole, and the trigger is hung in the hanging hole, so as to realize the linkage between the transmission member and the trigger, but there are defects of complex structure and complex assembly.

[0028] As an embodiment of the utility model, the locking portion 241 is a convex block protruding from the inner wall of the sleeve 24. The convex block design is easy to process and is not limited by the thickness of the sleeve wall; it ensures the effective buckling size of the lock and ensures the reliability of the lock; therefore, compared with the groove design, the convex block is easy to design and can effectively ensure the lock size. And because the locking portion is located inside the sleeve, that is, the convex block is hidden, it does not affect the appearance of the lighter; in order to simultaneously ensure the compact fit between the inner seat body and the sleeve, while ensuring that the outline size of the inner seat body is relatively close to the sleeve, an avoidance recess 2111 is provided on the inner seat body 211, and the locking portion 241 and the lock head 261 are both located in the avoidance recess 2111.

[0029] The unlocking key and the sliding lock 26 can be integrally formed or fixedly connected, but in this case the sliding lock 26 and the unlocking key 28 will not move synchronously; to avoid this problem, a pushing finger 281 is provided on the unlocking key 28, and a pushing surface 264 is provided on the sliding lock 26, and the pushing finger 281 of the unlocking key 28 pushes and cooperates with the pushing surface 264. This facilitates the processing and assembly of the components, and the sliding lock and the unlocking key are no longer synchronously following.

[0030] In order to facilitate the processing of the structure and the assembly of parts, the gun barrel 23 and the inner seat body 211 are integrally formed and assembled on the gun body 21. In this way, the inner seat body can be processed independently of the gun body, and the corresponding parts on the inner seat body are easy to assemble. A guide post 214 parallel to the gun barrel 23 is formed on the inner seat body 211, and a matching hole corresponding to the guide post is provided on the sleeve. The guide post plays a sliding guide role for the sleeve, and the sleeve return spring is installed on the guide post, which is convenient for the installation of the sleeve return spring.
