The cross plate 7 is used to connect the two rotating rods 8, and the end of the rotating rod 8 away from the cross plate 7 is rotatably connected to the connecting block 9. The two rotating rods 8 are used to connect the cross plate 7 and the connecting block 9. When the cross plate 7 moves, the two rotating rods 8 will produce different rotations according to the moving direction of the cross plate 7. The two connecting blocks 9 are respectively fixedly connected with the interlocking blocks 10 on one side away from the two rotating rods 8. The two connecting blocks 9 are connected to the two interlocking blocks 10, so that when the connecting block 9 is driven by the rotating rod 8, the interlocking blocks 10 will be driven to move together, and the cross plate 7 is away from the side of the pressure rod 6.

[0027] Working principle: When using the movable arm, first install the connecting arm 3 and the mounting block 2, and control the cross plate 7 to move toward the rotating rod 8 by pressing the pressure rod 6. The cross plate 7 will move along the slide bar 13 to squeeze the compression spring 14. When the cross plate 7 moves, the two rotating rods 8 will rotate in opposite directions under the pressure of the cross plate 7, so that the two connecting blocks 9 drive the engaging blocks 10 to move away from each other along the support rod 11, and then insert the mounting rod 4 on the left side of the connecting arm 3 into the mounting block 2. After the mounting rod 4 enters the mounting block 2, the pressure rod 6 can be released, and the compression spring 14 can be reset without pressure to generate thrust to push the cross plate 7 to move. Therefore, when the cross plate 7 moves, the two rotating rods 8 will reset and rotate relatively accordingly, thereby driving the connecting block 9 to move, so that the two engaging blocks 10 move toward each other along the support rod 11 and embed into the engaging groove 5 of the mounting rod 4, so that the connecting arm 3 is connected to the mounting block 2.
[0028] Secondly, when connecting the assembly rod 16, first pull the lever 17 so that the lever 17 drives the block 20 to move along the slide rod 19. When the lever 17 moves, the spring 18 will be squeezed. Then, the connecting tubes 15 at the front and rear ends of the assembly rod 16 are inserted into the connecting arm 3. The positions of the two connecting tubes 15 are adjusted so that the two blocks 20 can slide into the slots 21. Then, the lever 17 can be released. The spring 18 can be reset without the pressure of the lever 17 to generate a thrust to push the lever 17 to move, so that the block 20 slides into the slots 21, so that the connecting tube 15 is connected to the connecting arm 3, and the connection work is completed.
