[0032] The fixing mechanism 6 is arranged on the ground, so that when the device is disassembled from the driving mechanism 2, if the rotating table 4 needs to be operated alone, the two push plates 67 can be pushed to move towards the two sides. In the process of moving the push plate 67, the limiting frame 64 will be moved outward, so as to make the limiting spring 63 be compressed. At this time, the clamping block 65 at the outer end of the limiting frame 64 will be pulled out from the inner side of the clamping frame 66, and then the connecting shaft 62 can be smoothly taken out from between the two limiting frames 64. This makes the disassembly of the rotating table 4 extremely simple, and when installation is needed, the operation process is also simple and easy to operate.
