[0029] The connecting assembly 3 includes a connecting plate 300 fixedly installed at the bottom of the rotating rod 204. A rod 301 is inserted into one side of the connecting plate 300, and a stop block 302 is fixedly installed at one end of the rod 301. The two stops 302 are fixedly connected on one side by a handle 303. A return spring 304 is arranged around the surface of the rod 301. One end of the return spring 304 is fixedly connected to one side of the stop block 302, and the other end of the return spring 304 is fixedly connected to the surface of the connecting plate 300. The connecting assembly 3 facilitates the connection and positioning of components during use, thereby facilitating subsequent use and improving the connection stability of the mechanism. It also facilitates subsequent use and installation and positioning operations, thus improving the efficiency of the mechanism.

[0030] See Figure 1 Mounting plates 4 are fixedly installed at the four corners of the bottom of the base 1. Mounting plates 4 have mounting holes, which are oblong holes. The mounting plates 4 facilitate installation during use, thereby increasing the installation stability of the mechanism.

[0031] See Figure 1 An anti-slip ring is fixedly installed on the lower surface of the mounting plate 4 at the position corresponding to the mounting hole. The lower surface of the anti-slip ring has anti-slip texture and the anti-slip ring is made of rubber. The anti-slip ring is designed to prevent slippage during installation, thereby improving the installation stability of the mechanism.

[0032] See Figure 5 A cover 205 is fixedly installed on the top of the base 1. A door 206 is hinged to the front surface of the cover 205. A horizontal plate 207 is fixedly installed on one side of the door 206. A positioning block 208 is fixedly installed on one side of the cover 205. An insert plate 209 is inserted into the horizontal plate 207. The bottom of the insert plate 209 is inserted into the top of the positioning block 208.

[0036] During operation, the component to be connected is inserted into the bottom of the rotating rod 201, while another rotating shaft is inserted into the connecting plate 300. Then, one end of the insertion rod 301 is inserted into the surface of the rotating shaft, and the threaded rod 306 is tightened, connecting it to the handle 303 to prevent loosening. The motor 200 is then controlled to rotate, driving the first gear 202 on the rotating rod 201. Simultaneously, the first gear 202 drives the second gear 203, causing the connecting plate 300 on the rotating rod 204 to rotate. This facilitates transmission operations. The connecting component 3 facilitates connection and positioning of components during use, improving the connection stability and ease of use.
