[0010] In one of the embodiments, the mounting base is internally provided with at least one vertical plate, and the vertical plate is provided with a limiting groove for mounting the locking rod.

[0011] In the above technical solution, the locking rod is mounted on the vertical plate through the limiting groove on the vertical plate, and the limiting groove can limit the locking rod to move along a specified path.

[0012] In one of the embodiments, a buffer sleeve is mounted on the screw nut, and a shock isolation rubber pad is mounted between the driving motor and the mounting base.

[0013] In the above technical solution, the buffer sleeve can buffer when the screw nut contacts the mounting base, thereby relieving the impact force, and the shock isolation rubber pad is located between the driving motor and the mounting base, thereby preventing the vibration generated when the driving motor works from being transmitted to the mounting base.
