The first connecting shaft 2 and the second connecting shaft 3 are coaxial with the rod body 1 and are inserted from both ends of the rod body 1, and the first connecting shaft 2 and the second connecting shaft 3 are detachably connected.

[0032] Reference Figure 1 and Figure 2 A connecting piece is provided on the rod body 1 to drive the first connecting shaft 2 and the second connecting shaft 3 to rotate synchronously. A plurality of connecting grooves 5 are provided on the outer walls of the first connecting shaft 2 and the second connecting shaft 3 along the length direction. The connecting grooves 5 penetrate the end faces of the corresponding first connecting shaft 2 and the second connecting shaft 3 close to each other along the length direction. The connecting piece is a plurality of connecting rods 4 integrally formed on the inner wall of the rod body 1. The plurality of connecting rods 4 are evenly distributed along the circumferential direction of the axis of the rod body 1. The connecting rods 4 correspond to the connecting grooves 5 one by one, and the connecting rods 4 are smoothly abutted against the inner walls of the connecting grooves 5, which facilitates the movement of the rod body 1 relative to the first connecting shaft 2 and the second connecting shaft 3, and also facilitates the first connecting shaft 2 and the second connecting shaft 3 to drive the rod body 1 to rotate synchronously.

[0033] Reference Figure 1 and Figure 3 A positioning assembly is provided on the first connecting shaft 2 and the second connecting shaft 3 to prevent the rod body 1 from moving along the axis. The positioning assembly includes a positioning column 6 threadedly connected to the corresponding first connecting shaft 2 and the second connecting shaft 3. The positioning column 6 is located at both ends of the rod body 1. A positioning cylinder 7 is integrally formed on the positioning column 6. One end of the positioning cylinder 7 is connected to the positioning column 6, and the other end of the positioning cylinder 7 is tightly pressed against the end of the rod body 1, thereby fixing the rod body 1 on the first connecting shaft 2 and the second connecting shaft 3.

[0034] Reference Figure 1 and Figure 3 A plug-in groove 8 is provided at the end of the first connecting shaft 2, and a connecting block 9 inserted into the plug-in groove 8 is integrally formed at the end of the second connecting shaft 3. The plug-in groove 8 is a rectangular groove, and the connecting block 9 smoothly abuts against the inner wall of the plug-in groove 8. A mounting groove 10 is provided on the connecting block 9.

A clamping groove 11 is provided on the inner wall of the plug-in groove 8, and the clamping groove 11 corresponds to the clamping rod 13. When the end of the clamping rod 13 moves into the clamping groove 11, the connection between the first connecting shaft 2 and the second connecting shaft 3 is realized.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The connecting device also includes a driving mechanism for driving the clamping rod 13 to move toward the clamping groove 11 and inserting the end of the clamping rod 13 into the clamping groove 11. The second connecting shaft 3 is provided with a driving groove 20 along the axial direction. One end of the driving groove 20 passes through the second connecting shaft 3, and the other end of the driving groove 20 is connected with the mounting groove 10.

The driving platform 15 is in a truncated cone shape, and the end of the clamping rod 13 abuts against the side wall of the driving platform 15; a clamping spring 16 is arranged in the clamping groove 11, and the clamping spring 16 connects the two clamping rods 13 and pulls the two clamping rods 13 to move in a direction close to each other. A clearance groove 17 is arranged on the driving platform 15, and the clamping spring 16 is located in the clearance groove 17 to avoid interference.

[0036] The driving rod 14 drives the driving platform 15 to move toward the first connecting shaft 2. Under the action of the driving platform 15, the clamping rod 13 moves toward the corresponding clamping groove 11 and inserts the end portion into the clamping groove 11 to realize the connection between the first connecting shaft 2 and the second connecting shaft 3. When the driving rod 14 drives the driving platform 15 to move in the opposite direction, under the action of the clamping spring 16, the clamping rod 13 is disengaged from the corresponding clamping groove 11, so as to facilitate the separation of the first connecting shaft 2 and the second connecting shaft 3.

The driving assembly includes a driving block 18 threadedly connected to the end of the driving groove 20. A driving spring 19 is installed in the driving groove 20 between the driving block 18 and the driving rod 14. By rotating the driving block 18, the driving block 18 compresses the driving spring 19, and the driving spring 19 acts on the driving rod 14, thereby driving the driving platform 15 to move.
