As the transmission shaft 223a rotates, the slider 223b and the slide plate 222 are driven to move. The slide plate 222 drives the mounting shell 21 to move to the middle position of the slot plate 221. The motor 24 is started. The motor 24 drives the rotating shaft 23 to rotate in the mounting shell 21. The fixed seat 25 drives the telescopic part 26 to offset, thereby changing the use direction of the friction block body 28. Then, the pin 292 is used to connect the storage plate 291 and the limit plate 293 to prevent the fixed seat 25 from offsetting.
