[0045] The present invention discloses a coupling and a manufacturing process thereof, which have the following beneficial effects:

[0046] 1.

[0047] 2. The limiting plate, the arc plate, the guide column, the fixing seat and the insertion plate cooperate with each other. The limiting plate limits the top of the support tube, the arc plate connects the adjacent limiting plates in series, and the insertion plate and the fixing seat guide the installation of the limiting plate, which is conducive to the installation and disassembly of the support tube, so as to replace the support tubes with different inner diameters, and to adapt to the connection and use of shafts of different sizes;

[0048] 3. The sliding frame, the support frame, the locking plate, the connecting tube, the sliding rod, the first spring, the mounting rod, the sliding ring, the mounting ring, the operating column and the second spring cooperate with each other. The sliding frame drives the locking plate to limit the position of the support frame. The support frame limits the positions of the second slide plate and the anti-slip tube. The elastic force of the first spring pushes the sliding frame to slide horizontally. The sliding frame separates the locking plate from the support frame and keeps it away from the top of the second slide plate, which is conducive to independently replacing the anti-slip tube without disassembling the support tube, thereby saving operation steps and facilitating operation.

[0049] 4. The auxiliary frame, the clamping plate and the anti-slipping column cooperate with each other. The auxiliary frame drives the clamping plate to limit the relative position of the insertion plate and the fixing seat. The auxiliary frame drives the anti-slipping column to move. The anti-slipping column presses against the end of the fastening bolt, which is conducive to the installation and removal of the limit plate, so as to install and remove the support tube. At the same time, it is conducive to the anti-loosening protection of the fastening bolt, which is convenient to prevent the fastening bolt from moving at will;

[0050] 5. The support rod, connecting plate, connecting column, connecting frame and baffle cooperate with each other. After the connecting plate and the sliding frame slide away from the top of the second slide board, they are socketed with the connecting column to limit the sliding frame. The connecting frame and the baffle limit the sliding position of the sliding frame. The baffle limits the rotation position of the connecting plate, which is beneficial to the anti-slip position limitation of the sliding frame and the storage operation of the sliding frame to operate the anti-slip cylinder.
