[0032] Reference Figure 1-Figure 2 The inner walls of the front and rear sides of the clamping arm 6 are respectively fixedly connected with a group of limit slide rails 7, and the clamping arm 6 is internally slidably connected with a limit block 8. The left side of the limit block 8 is provided with a rough texture to increase the friction force. The left end of the limit block 8 contacts the right side of the rightmost limit strip 2. At this time, when the limit block 8 is squeezed, friction will be generated between the limit strip 2, so that the sliding sleeve 5 cannot slide up and down. A group of transverse sliding grooves 9 are respectively opened on the front and rear sides of the limit block 8. The outer periphery of the limit slide rail 7 is slidably connected to the inside of the transverse sliding groove 9. The limit slide rail 7 limits the limit block 8 to only slide left and right along the outer wall of the limit slide rail 7. An elastic extrusion block 10 is fixedly connected to the right side of the limit block 8. The elastic extrusion block 10 can produce a A certain degree of elastic deformation is generated, compression is generated, and elastic force is generated. An extrusion rod 11 is hinged inside the clamping arm 6. The distance between the hinge point of the extrusion rod 11 and the top is greater than the distance between the left and right sides of the extrusion rod 11.

When the extrusion rod 11 rotates, the top end of the extrusion rod 11 will squeeze the elastic extrusion block 10 and the lower positioning block 13.

At this time, pull the extrusion rod 11 to the upper right, and the extrusion rod 11 rotates counterclockwise. The elastic extrusion block 10 is squeezed on the left side of the extrusion rod 11. The elastic extrusion block 10 is deformed and generates elastic force, which squeezes the limit block 8, so that the limit block 8 squeezes the limit strip 2 to the left, so that the sliding sleeve 5 is fixed. At the same time, the top of the extrusion rod 11 squeezes the lower positioning block 13, so that the lower positioning block 13 is lifted, and the workpiece is squeezed to fix the workpiece, thereby conveniently completing the positioning and clamping of the workpiece at a low cost. When you want to replace a support column 1 of a different length, unscrew the bolts on the mounting plate 14, lift the support column 1 upward, remove the old support column 1, and then insert the support column 1 of the new height between the four groups of support rods 17. After the knob bolts are installed, the height of the support column 1 can be adjusted without changing the position of the base assembly, thereby achieving positioning and clamping at different heights.
