A cross bar 51 which is integrally formed with the telescopic column 5 is provided on the top of the telescopic column 5. A clamping device 7 is provided in the cross bar 51. A pair of clamping devices 7 are provided. The other clamping device 7 is vertically arranged inside the base 1. The movable column 2 is a hollow structure. A drawer 8 is slidably installed on one side of the movable column 2. Some mechanical spindle disassembly and assembly tools or parts that need to be replaced for the mechanical spindle can be placed in the drawer 8. The movable column 2 and the fixed column 3 are fixedly installed with protective pads facing the side of the supporting device. The protective pads are made of flexible materials such as rubber, which can effectively prevent the mechanical spindle from colliding with the movable column 2 or the fixed column 3 when fixed.

[0020] like Figure 2 Figure 3The supporting device shown includes a slider 4, a connecting column 41 is fixedly installed on the top of the slider 4, a clamp 42 is fixedly installed on the top of the connecting column 41, a lifting device 6 includes a threaded hole 61, the threaded hole 61 is opened inside the telescopic column 5, a threaded column 62 is threadedly connected to the threaded hole 61, a turbine 63 integrally formed with the threaded column 62 is provided at the bottom of the threaded column 62, a worm 64 is rotatably connected to one side of the turbine 63, the worm 64 passes through a wall of the fixed column 3 and is fixedly connected to a handle 65, the clamping device 7 includes a cylinder 71, one end of the cylinder 71 is large and the other end is small, the large end of the cylinder 71 is in contact with a support plate 72, a plurality of springs 73 are provided at one end of the support plate 72, one end of the spring 73 is fixedly connected to the support plate 72, and the other end is in contact with the inner wall of the cross bar 51. In actual use, if you want to horizontally fix the mechanical spindle, you only need to place the mechanical spindle on the clamp. The tool 42 is then slid into the movable column 2. The movable column 2 is slid to a suitable position and then fixed by the bolt 22 to fix the mechanical spindle in the horizontal direction. If you want to fix the mechanical spindle vertically, you only need to hold the handle 65 and rotate it. The rotation of the handle 65 drives the worm 64 to rotate, and the rotation of the worm 64 drives the turbine 63 to rotate, so that the threaded column 62 rotates in the threaded hole 61, and then the telescopic column 5 moves. At this time, the mechanical spindle is placed on the surface of the cylinder 71, and then the height of the telescopic column 5 is controlled by rotating the handle, so that the telescopic column 5 drives the cross bar 51 to squeeze the mechanical spindle, and the mechanical spindle will push the cylinder 71 of the appropriate size to squeeze the support plate 72 to compress the spring 73. At this time, the cylinder 71 not pushed by the mechanical spindle can effectively limit the left and right movement direction of the mechanical spindle, thereby improving the fixing effect and facilitating the disassembly and assembly of the mechanical spindle.
