The spring 310 provides sufficient elastic force so that the slide groove 35 can maintain a good position fixation in the fixing seat 31 with the elastic force of the spring 310. A fixing plate 36 is fixedly connected to one side of the base 2. A card rod 37 is inserted into the fixing seat 31 for sliding movement. A rebound mechanism 38 is provided inside the fixing seat 31. A slide rod 39 is fixedly connected to the fixing seat 31, and a spring 310 is sleeved on the outer surface of the slide rod 39.

[0023] Example 2

[0024] like Figure 4As shown, the rebound mechanism 38 includes a limit plate 381 fixedly sleeved on the outer surface of the clamping rod 37, and a tension spring 382 is sleeved on the outer surface of the clamping rod 37. A limit groove matched with the limit plate 381 is opened inside the fixed seat 31. By opening the limit groove, the limit plate 381 can move normally inside the fixed seat 31. One end of the tension spring 382 is welded to one side of the inner wall of the limit groove, and the other end of the tension spring 382 is welded to one side of the limit plate 381. By setting the tension spring 382, ​​the tension spring 382 provides sufficient tension, so that the limit plate 381 can be actively moved inside the fixed seat 31 with the help of the tension of the tension spring 382.

[0025] Working principle:

[0026] like Figure 1-4 As shown, during replacement, the push block 33 is first pushed to move, and the push block 33 moves during the movement of the top plate 32, and the top plate 32 moves during the movement of the connecting block 34, and the connecting block 34 moves inside the fixed seat 31, and drives the slider 35 to move, and the slider 35 slides on the outer surface of the slide rod 39. As the slider 35 moves, the shape of the spring 310 is gradually changed by the thrust, and as the top plate 32 moves, the top plate 32 gradually disengages from the clamping rod 37, until the push block 33 is pushed until the top plate 32 is completely disengaged from the clamping rod 37, and the position after the push block 33 is pushed is kept stationary, the top plate 32 contacts the clamping rod 37, and the clamping rod 37 is inserted into the fixed plate 36, the tension spring 382 is in a stressed deformation state, and when the top plate 3 2 is separated from the clamping rod 37, the tension spring 382 is no longer affected by the force, and its shape gradually recovers, driving the limit plate 381 to move. The limit plate 381 moves inside the fixed seat 31 and drives the clamping rod 37 to move. One end of the clamping rod 37 gradually moves out from the inside of the fixed plate 36, and the other end gradually moves out from the inside of the fixed seat 31, and releases the push block 33 that keeps the pushing position immobile, until the clamping rod 37 is completely moved out from the inside of the fixed plate 36, dragging the base 2 to move. During the movement of the base 2, the fixing plate 36 is driven to move, and the fixing plate 36 slides inside the fixed seat 31 and gradually separates from the fixed seat 31 until the original base 2 on the fixed seat 31 is completely disassembled and the corresponding base 2 is replaced and fixed.
