Furthermore, an upper supporting plate is fixedly connected between the fixing plates on the two sides, a front hook is fixedly connected above the upper supporting plate, and a through hole is formed below the front hook.

Furthermore, the elastic column is obliquely arranged and is made of rubber.

Furthermore, one end of the spring is fixed on the lower part of the electric push rod, and the other end of the spring is fixedly connected with the fixed pasting disk.

Further, the lower surface of the fixed pasting disc is fixedly connected with anti-skid grains.

Furthermore, a fixed rope is fixedly connected to the hinged shaft of the side fixing plate and the front movable hook, and the fixed rope penetrates through the through hole.

The utility model has the advantages that:

the utility model discloses an activity of movable hook before electric putter promotes for fixed subsides dish and the distance between the preceding movable hook are variable, the fixed axle that can not the diameter of being convenient for, and the fixed rope of accessible is fixed it once more, increases the fixity, and the antiskid line can prevent to press from both sides the axle removal of establishing, and the distance of fixed subsides dish can conveniently be adjusted to elasticity post and spring, increases the fixity, and it has simple structure, adjusts back safety fixed, advantage such as with low costs.
