[0027] Reference Figures 2-3As shown, the fixing mechanism 2 includes a rotating rod 22, which transmits power from the crank handle 21 to drive the first bevel gear 29 to rotate. The rotating rod 22 is rotatably connected to the inner wall of the base 1. The crank handle 21 is fixedly connected to the outer wall of the rotating rod 22. The crank handle 21 drives the rotating rod 22 to rotate and start the fixing mechanism 2. The first bevel gear 29 is fixedly connected to the outer wall of the rotating rod 22. The first bevel gear 29 is connected to the rotating rod 22 to receive and transmit power. The first bevel gear 29 meshes with a second bevel gear 28. The second bevel gear 28 is rotatably connected to the inner wall of the bottom end of the base 1. The second bevel gear 28 connects the first bevel gear 29 and a third bevel gear 27 to transmit power. The second bevel gear 28 meshes with the third bevel gear 27. The third bevel gear 27 is rotatably connected to the support on the inner wall of the base 1. 7 transmits power and changes direction to drive the threaded rod 26 to rotate. The third bevel gear 27 is fixedly connected to the threaded rod 26. The threaded rod 26 is rotatably connected to the inner wall support of the base 1. The threaded rod 26 cooperates with the threaded block 25 to convert the rotational motion into linear motion. The outer wall of the threaded rod 26 is threadedly connected to the threaded block 25. The threaded block 25 is slidably connected in the groove 210 in the middle of the inner wall of the base 1. The threaded block 25 moves under the action of the threaded rod 26, driving the clamping block 23. The top outer wall of the threaded block 25 is fixedly connected to the clamping block 23. The clamping block 23 can clamp and fix the main unit to prevent it from moving or shaking on the base 1. The bottom outer wall of the clamping block 23 is fixedly connected to the slider 24. The slider 24 is slidably connected in the grooves 210 at both ends. The slider 24 slides in the grooves 210 to guide the clamping block 23 to move smoothly.

[0028] Reference Figures 4-6 As shown, the extension mechanism 3 includes a connecting rod 32, which connects the handle 31 and the fixing rod 33 to transmit moving force. The connecting rod 32 is slidably connected to the inner wall of the base 1 and elastically connected to the inner wall of the base 1 by a spring 34. One end of the spring 34 is fixedly connected to the outer wall of the top end of the connecting rod 32, and the other end of the spring 34 is fixedly connected to the inner wall of the base 1.

The guide block 35 is inserted into the fixing groove 37. Several sets of slots 36 are opened on the bottom outer wall of the guide block 35. The guide block 35 is inserted into the fixing groove 37 to connect two sets of base 1 and guide the fixing rod 33 to snap into the slot 36.

[0029] In use, the rocker arm 21 is first turned to rotate the rotating rod 22, causing the first bevel gear 29 to mesh with the second bevel gear 28, which in turn drives the third bevel gear 27 to rotate, driving the threaded rod 26 to rotate. The threaded block 25 moves along the slide groove 210 under the action of the threaded rod 26, causing the clamping block 23 to slide and clamp the main unit in the slide groove 210 through the slider 24, thereby completing the fixation of the main unit.

[0030] When expansion is needed, the guide block 35 is inserted into the fixing groove 37 of the base 1, and the fixing rod 33 slides into the guide block 35 slot 36 through the top inclined surface. The spring 34 resets and locks the fixing rod 33, thus completing the bracket expansion. When retraction is needed, the handle 31 is pulled down to drive the fixing rod 33 out of the slot 36, and the base 1 that needs to be disassembled is pulled outward to disengage the guide block 35 from the fixing groove 37 of the other set of base 1, thereby completing the separation of the two sets of brackets.
