[0030] Specifically, when in use, the motor 8 drives the threaded rotating rod 10 to rotate, and the threaded rotating rod 10 drives the first support seat 14 to slide forward and backward on the top of the base 1. When the first support seat 14 slides forward, it will give an upward force to the lifting rod 17, and the lifting rod 17 gives an upward force to the second support seat 29 through the fixing pin 16, driving the rotating plate 4 to achieve angular rotation. When using the equipment, in order to reduce wear, the lubricating oil inside the oil tank 9 is injected into the oil inlet of the oil pump through the oil pipe 25 through the oil pump 11, and then the lubricating oil is injected into the brush 24 inside the cylinder 15 through the telescopic hose 13. As the first support seat 14 slides, the brush 24 evenly applies the attached lubricating oil to the surface of the threaded rotating rod 10, thereby achieving the purpose of reducing equipment wear and increasing equipment life.

[0031] The fixing device includes an outer box 21, which is fixedly connected to the right side of the first support seat 14.

[0032] Specifically, when in use, the handle 27 is pulled downward to compress the spring 22 through the force plate 23, and then the positioning pin 26 is inserted into the aperture of the fixing pin 16. When the handle 27 is released, the spring 22 releases the pressure and returns to its original state, which will exert an upward force on the force plate 23, thereby fixing the fixing device on the fixing pin 16. When disassembly is required, only the handle 27 needs to be pulled downward to remove the positioning pin 26, and the fixing pins 16 at both ends of the lifting rod 17 are pulled out, and a new lifting rod 17 is replaced. To install the lifting rod 17, only the fixing pins 16 need to be inserted at both ends of the lifting rod 17, and then the fixing pins 16 are inserted into the apertures of the two fixing pins 16.

[0033] Working principle: The transmission device includes a threaded rotating rod 10, a first fixed plate 12, a second fixed plate 18, a motor 8 and a support seat 14. When the equipment is used, the motor 8 is started to drive the threaded rotating rod 10 to rotate and the transmission device is running. The support seat 14 moves horizontally forward after being acted upon by the transmission device. At this time, the oil pump 11 is started, and the lubricating oil in the oil tank 9 is transported to the oil inlet of the oil pump 11 through the oil pipe 25. Then the oil pump 11 pumps the oil into the brush 24 located inside the cylinder 15 through the telescopic hose 13. During the movement of the brush 24 with the support seat 14, the lubricating oil is evenly brushed on the surface of the threaded rotating rod 10, completing the preliminary maintenance of the threaded rotating rod 10. The spring pin 20, as a fixing device, includes an outer box 21, a spring 22, a force plate 23, a positioning pin 26 and a handle 27. When in use, the outer box 21 is fixedly connected to the appropriate position of the support seat 14. When the positioning pin 26 is inserted into the appropriate hole diameter, the spring 22 changes from the squeezed state to the released state, giving the force-bearing plate 23 an upward force. The positioning pin 26 is firmly inserted into the hole. If the threaded pin 20 needs to be pulled out, just gently pull the handle 27.
