[0075] Reference Figure 2 and Figure 3 When the lock core 301 is in the unlocked state, the lock core 301 moves along the axis of the mounting cylinder 100, and the push plate 302 can interfere with the movable seat 501 in the trigger structure 500. When the lock core 301 is in the locked state, the lock core 301 moves along the axis of the mounting cylinder 100, and the push plate 302 cannot drive the movable seat 501 to move.

[0076] The implementation principle of Example 1 of the present application is: when the push button switch needs to be started, the lock cylinder 301 is unlocked by the key and the lock cylinder 301 is driven to rotate, and then the lock cylinder 301 is pressed to make the lock cylinder 301 and the push plate 302 move toward the fixed seat 401, and the push plate 302 contacts the movable seat 501 and drives the movable seat 501 to move, and the movable seat 501 drives the driving assembly 504 to push the swing member 424, and the swing member 424 drives the movable contact piece 423 to contact the first static contact 428, and at the same time the operating spring 528 is compressed and deformed, and the locking rod 207 passes through the locking slide 516 and moves into the positioning groove 515 to realize the opening of the push button switch.

[0077] When the push button switch needs to be turned off, the lock core 301 is pressed, so that the lock core 301 and the push plate 302 move toward the fixed seat 401, and the push plate 302 contacts the movable seat 501 and drives the movable seat 501 and the first operating plate 508 to move, so that the locking rod 207 in the positioning groove 515 passes through the unlocking slide 517 and returns to the initial groove 514, so that the locking rod 207 no longer locks the first operating plate 508, and the operating spring 528 drives the movable seat 501 to reset, so that the driving assembly 504 no longer applies force to the swinging member 424, so that the movable contact piece 423 contacts the second static contact 430 again, and the push button switch is turned off.

The second unlocking rod 703 is provided with a second chamfer, which is located at the intersection of the inner wall of the second unlocking rod 703 away from the button structure 300 and the side of the second unlocking rod 703 facing the second linkage rod 704.

[0087] Reference Figure 9When the base assembly 404 is installed on the storage cylinder 200, the second fixing block 408 and the second unlocking rod 703 both conflict with the inner wall of the second fixing hole 203 close to the button structure 300. At this time, the second linkage rod 704 is inserted into the second limiting groove 705, and the second unlocking rod 703 cannot move toward the button structure 300, making it difficult for the second positioning block 701 to disengage from the second positioning hole 445.

[0088] The implementation principle of Example 2 is as follows: the base structure is installed between the first fixed plate 402 and the second fixed plate 403. When the first positioning groove 440 is aligned with the first positioning hole 442, the first positioning spring 602 drives the first positioning block 601 to be inserted into the first positioning hole 442 to position the first base 410. At the same time, the first linkage rod 604 is pushed by the first positioning block 601 and inserted into the first limiting groove 605; similarly, when the second positioning groove 443 is aligned with the second positioning hole 445, the second positioning spring 702 drives the second positioning block 701 to be inserted into the second positioning hole 445 to position the second base 411. At the same time, the second linkage rod 704 is pushed by the second positioning block 701 and inserted into the second limiting groove 705.

[0089] After the base structure 400 is separated from the storage cylinder 200, the first unlocking rod 603 is driven to move, and the first unlocking rod 603 pushes the first linkage rod 604 through the first chamfer, and the first linkage rod 604 then drives the first positioning block 601 to disengage from the first positioning hole 442, thereby releasing the lock between the first base 410 and the first fixed plate 402. Similarly, the second unlocking rod 703 is driven to move, releasing the lock between the second base 411 and the second fixed plate 403, and it is not easy to remove the base assembly 404 from between the first fixed plate 402 and the second fixed plate 403.
