Specifically, a through hole 21 is formed in a sidewall of the switch button 20, and both ends of the hook respectively extend into the insertion groove 12 and the through hole 21 to connect the lock shaft 10 with the switch button 20. Like this, plug-in connection makes the connected mode of claw and lock axle 10 and shift knob 20 be for dismantling the connection, and then makes things convenient for the staff to change lock axle 10 or the different shift knob 20 of locking, enlarges shift knob blocking device's application scope.
The end surface of the lock shaft 10 near the switch knob 20 may abut against the pressing surface of the switch knob 20 or may be a predetermined distance.
As shown in fig. 3 and 5, in the switch knob locking device of the first embodiment, the claw includes a body portion 61, an insertion section 62, and a connection section 63. Wherein the plug section 62 is arranged at a first end of the body portion 61, and the plug section 62 extends into the plug groove 12. The connecting section 63 is disposed at the second end of the body portion 61 and projects in the same direction as the plug section 62. Therefore, the section of the claw is in a U-shaped structure, and the connecting section 63 and the inserting section 62 extend out in the same direction, so that the claw is easier to install on one hand; on the other hand, the lock shaft 10 and the switch button 20 are located in the same vertical direction (in the same direction in which the switch button 20 is pressed), so that it is possible to ensure that the switch button 20 is locked by locking the lock shaft 10. The structure is simple and easy to process.
Specifically, the insertion section 62 is inserted into the insertion groove 12 of the lock shaft 10, and the connection section 63 is inserted into the through hole 21 of the switch button 20, so that the switch button 20 is connected with the lock shaft 10.
