The first lifting block 3 is a U-shaped block. A rotating block 5 is rotatably connected to the first lifting block 3. A rotating hole is formed in the first lifting block 3. Two sides of the rotating block 5 are provided with rotating shafts. The first lifting block 3 is rotatably connected to the rotating block 5 through the rotating hole and the rotating shafts. The outer diameter of a bearing 6 is fixed within the rotating block 5. The inner diameter of the bearing 6 is fixed to the outer diameter of a core shaft 7. A rubber layer 701 is wrapped around the core shaft 7. A rotating handle 702 is provided on the core shaft 7 between the rubber layer 701 and the bearing 6. An avoidance opening 103 is formed in the base 1 at the relative position of the rotating handle 702. A locking mechanism is provided at the other end of the core shaft 7. The locking mechanism includes a second lifting block 4 and a locking block 401. An arc-shaped notch is formed in the middle of the second lifting block 4.

The locking block 401 has the same structure as the second lifting block 4. Clamping blocks 403 are provided on both sides of the arc-shaped notch of the locking block 401. The second lifting block 4 and the locking block 401 are slidably clamped together through the clamping blocks 403 and the card slots 402.

[0024] As a preferred technical solution of the present utility model, a first lifting spring 2 and a second lifting spring 201 are fixedly connected inside the base 1. The first lifting spring 2 includes a cavity 204. The cavity 204 is fixedly connected to the inside of the base 1 below the first lifting block 3.
