[0031] Specifically, the adjusting seat 101 includes a first plate body 111, a second plate body 112, a third plate body 113, a guide rod 114, and a nut 115. The first plate body 111, the second plate body 112, and the third plate body 113 are arranged in order from top to bottom. The first plate body 111 has a guide rod 114 vertically arranged at the top end of the two ends of the horizontal top surface. The guide rod 114 penetrates the second plate body 112 and the third plate body 113 in order and is locked by the nut 115. A spring 116 is sleeved on the guide rod 114 between the first plate body 111 and the second plate body 112.
[0032] Through the cooperation of the guide rod 114 and the nut 115, the distance between the first plate body 111 and the third plate body 113 is adjusted by rotating the nut 115, and the lifting support is performed by the elasticity of the spring 116.
