Specific implementation

[0021] The utility model will be further described below according to the drawings.

[0022] As Figures 1 to 5 shown, the front lower end of the base plate 3 is respectively provided with the first positioning shaft 1 and the second positioning shaft 2, the rear side of the base plate 3 is provided with the clamping device 4, the clamping device 4 includes the clamping rod 4-1, the rotating shaft 4-2, the spring 4-6 and the bolt 4-3 arranged on the left and right sides, the rear side of the base plate 3 is provided with the rotating shaft 4-2, the outer side of the rotating shaft 4-2 is respectively sleeved with one end of the clamping rod 4-1, the front side of the clamping rod 4-1 is provided with the bolt 4-3, one end of the bolt 4-3 is located on the outer side of the clamping rod 4-1 and is fastened through the nut 4-4, and the other end of the bolt 4-3 penetrates through the clamping rod 4-1.

[0023] The left and right sides of the base plate 3 are respectively provided with the L-shaped limiting seat 4-7, and the end close to the base plate 3 of the limiting seat 4-7 is in contact with the base plate 3. The outer side of the bolt 4-3 is provided with the sleeve 4-5, one end of the sleeve 4-5 penetrates through the limiting seat 4-7 and is sleeved with the shaft check ring 4-9 to prevent the sleeve 4-5 from loosening. The outer side of the sleeve 4-5 is sleeved with the spring 4-6, one end of the spring 4-6 abuts against the inner wall of the limiting seat 4-7, and the other end of the spring 4-6 abuts against the head of the bolt 4-3. In specific use, the limiting seat 4-7 and the spring 4-6 abut against one end of the spring 4-6, the clamping rod 4-1 drives the bolt 4-3 to move away from the base plate 3, and the spring 4-6 is extruded and shrunk.
