[0033] The working principle of this utility model:

[0034] When installing and fixing, align the card blocks 5 on both sides of the movement 2 with the docking grooves 32 and insert them into the card plate 31. After insertion, push the movement 2 toward the rear end in the card plate 31. At this time, the card blocks 5 will be staggered with the docking grooves 32 to position the movement 2. While pushing the movement 2 backward, it will drive the connector 6 to be inserted into the box body 41, squeezing the lock head 422 in the box body 41, so that the lock head 422 is squeezed and moves upward on the surface of the positioning rod 421, and at the same time squeeze the push spring head 423. After the connector 6 is fully inserted into the box body 41, the lock head 422 is no longer squeezed. At this time, the push spring head 423 will rebound and push the lock head 422 downward to clamp the connector 6, thereby completing the installation and fixation of the movement 2. When the movement 2 is subsequently disassembled, the button 444 is pulled backward to drive the squeezing block 442 to move backward on the surface of the slide rod 441. While the squeezing block 442 moves backward, it squeezes the rear ends of the two connecting parts 432, causing the two connecting parts 432 to be squeezed and rotated counterclockwise on the surfaces of the two rotating shafts 431. While the two connecting parts 432 rotate counterclockwise, they drive the two pressure rods 433 to move in the two travel grooves 424, moving and squeezing the inner walls of the travel grooves 424, causing the lock head 422 to be squeezed and move upward on the surface of the positioning rod 421, releasing the clamping of the connecting head 6, releasing the fixation of the movement 2, and then pulling the movement 2 forward in the clamping plate 31 until the clamping block 5 corresponds to the docking groove 32, and then the movement 2 can be taken out upward.
