[0008] According to a further technical solution, a limiting groove is provided on the outer wall of the slide rod, a limiting plate is fixedly connected to the inner wall of the slide cylinder, and the limiting plate is slidably connected to the limiting groove.

[0009] According to a further technical solution, the end faces of the limiting plate and the locking groove that are close to each other are coplanar.

[0010] A further technical solution is that the thrust assembly includes a placement frame, a rotating shaft, a gear, a motor and a fixed rod; the placement frame is fixedly connected to the motor, the driving end of the motor is fixedly connected to the rotating shaft, the rotating shaft is fixedly sleeved with a gear, the gear is meshed with the rack, and the placement frame is also fixedly connected to a plurality of fixed rods, and the fixed rods are cooperatively connected to the receiving plate.

[0011] A further technical solution is that a fixing ring is fixedly connected to the outer wall of the fixing rod, and the fixing ring abuts against a receiving plate. A plurality of matching holes are opened on the receiving plate, and the matching holes correspond one-to-one to the fixing rods. The fixing rods are inserted into the matching holes, and a clamping rod is also inserted into the fixing rods.
