By setting a clamping component, turning the handle drives the threaded rod to rotate. The threaded rod drives the screw sleeve to rotate in the bearing. During the downward movement of the threaded rod, the bearing is driven to descend synchronously. During the movement of the bearing, the lower arc-shaped clamping block and the anti-slip pad are driven to move until the handle is turned and the arc-shaped clamping block stops moving. The arc-shaped clamping block and the connecting pipe cooperate to clamp the busbars. At the same time, while the anti-slip pad achieves anti-slip, it can also protect the surface of the tubular busbars. BRIEF DESCRIPTION OF THE DRAWINGS

Threaded holes are symmetrically provided on the lower side wall of the connection box 1, so that when it is inconvenient to hang the connection box 1, it can be supported from below.

[0029] Two fixing assemblies 6 are symmetrically installed on the inner side wall of the connection box 1 to facilitate fixing the connection of the busbar. The front side wall of the fixing plate 601 of the fixing assembly 6 is installed with a protective layer 602, and the rear side wall of the fixing plate 601 is installed with a return spring 603. The inner side wall of the return spring 603 is installed with a pull rod 604, and the front side wall of the pull rod 604 is installed with the fixing plate 601;

The inner side wall of the connection box 1 is detachably fixedly connected to the fixed end of the return spring 603 to fix the return spring 603. The moving end of the return spring 603 is detachably fixedly connected to the rear side wall of the fixing plate 601, so that the return spring 603 and the fixing plate 601 move synchronously. The front side wall of the fixing plate 601 is fitted and connected to the protective layer 602, and the protective layer 602 protects the connection.

[0031] The rear side wall of the fixed plate 601 is detachably fixedly connected to the pull rod 604, so that pulling the pull rod 604 can drive the fixed plate 601 to move. The outer side wall of the pull rod 604 is slidably connected to the connecting box 1 to facilitate the movement of the pull rod 604.

[0032] When the above setting is in use, the operator inserts the connecting pipes 2 at both ends of the busbar into the moving connection box 1, pulls the pull rod 604 to drive the fixed plate 601 to move, compresses the return spring 603, connects the joints of the busbars in the connection box 1.

[0033] Embodiment 2

[0034] The difference between Embodiment 2 and Embodiment 1 is that it further discloses that as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, clamping assemblies 7 are installed on the inner side walls of the connecting pipes 2 to facilitate clamping of the busbars in the connecting pipes 2. A handle 702 is installed on the upper side wall of the threaded rod 701 of the clamping assembly 7, a screw sleeve 7011 is installed on the lower side of the threaded rod 701, a bearing 703 is arranged on the outer side wall of the screw sleeve 7011, an arc-shaped clamping block 704 is installed on the lower side wall of the bearing 703, and an anti-slip pad 705 is installed on the lower side wall of the arc-shaped clamping block 704;

[0035] An arc-shaped clamping block 704 is arranged on the inner side wall of the connecting pipe 2. The arc-shaped clamping block 704 is arc-shaped downward to facilitate clamping of the busbar. The lower side wall of the arc-shaped clamping block 704 is in fit connection with the anti-slip pad 705, and the anti-slip pad 705 plays an anti-slip effect;

The upper side wall of the screw sleeve 7011 is detachably and fixedly connected with the threaded rod 701 to achieve the effect of synchronous movement. The upper side wall of the threaded rod 701 is detachably and fixedly connected with the handle 702;

[0037] A threaded through hole is formed in the upper side wall of the connecting pipe 2. The connecting pipe 2 is threadedly connected with the threaded rod 701 through the threaded through hole to prevent the threaded rod 701 from loosening;

[0038] When the above settings are in use, after the connection of the busbars is fixed, rotate the handle 702 to drive the threaded rod 701 to rotate. The threaded rod 701 drives the nut sleeve 7011 to rotate in the bearing 703. During the downward movement of the threaded rod 701, the bearing 703 is driven to descend synchronously. During the movement of the bearing 703, the lower arc-shaped clamping block 704 and the anti-slip pad 705 are driven to move until the handle 702 is rotated and the arc-shaped clamping block 704 stops moving. The arc-shaped clamping block 704 and the connecting pipe 2 cooperate with each other to clamp the busbars. At the same time, while the anti-slip pad 705 achieves anti-slip, it can also protect the surface of the tubular busbars.
