[0026] See Figures 1 to 7, this embodiment provides a switch locking mechanism, including: a bottom case 1, on which an installation groove 101 is opened; a toggle lever 2, which has a locking motion block 201; a sliding rod 3, the sliding rod 3 includes a pressing rod 301 and a sliding base body 302, the sliding base body 302 is slidably arranged in the installation groove 101, the pressing rod 301 is arranged on the sliding base body 302, and a locking abutting block 3021 is arranged on the sliding base body 302. When the toggle lever 2 is in the locked state, the locking motion block 201 abuts against the locking abutting block 3021, so that the sliding rod 3 is in the locked state. Function: In this utility model, by arranging the locking abutting block 3021 on the sliding rod 3 and the locking motion block 201 on the toggle lever 2, during the left and right sliding process of the sliding rod 3, when the locking abutting block 3021 abuts against the locking motion block 201, the sliding rod 3 immediately stops sliding left and right to achieve the locking effect. In this utility model, by toggling the toggle lever 2, the linkage effect between the sliding rod 3 and the start-stop mechanism can be easily realized, the operation is simple, and the reliability of switch locking is greatly improved.

[0027] Specifically, it further includes a first limiting block 103. A limiting sliding groove 3022 is opened on the sliding base body 302, and the limiting sliding groove 3022 is slidably sleeved outside the first limiting block 103. In actual use, the sliding base body 302 can slide left and right along the first limiting block 103 through the limiting sliding groove 3022.

[0028] Specifically, a locking groove is opened on the sliding base body 302, and the locking abutting block 3021 is arranged in the locking groove, so that the locking groove is divided into two parts, forming a first unlocking sliding groove 3023 and a second unlocking sliding groove 3024. In actual use, the sliding rod 3 can realize left and right reciprocating linear motion with the locking motion block 201 through the first unlocking sliding groove 3023 and the second unlocking sliding groove 3024.

[0029] Specifically, it further includes a positioning member. A positioning channel 3025 is opened on the sliding base body 302, and the positioning member is inserted through the positioning channel 3025.

[0030] Specifically, the positioning member includes a positioning column 4 and a trigger spring 5. The positioning column 4 is arranged on the bottom case 1, the trigger spring 5 is sleeved outside the positioning column 4, and the trigger spring 5 is inserted through the positioning channel 3025.
