DETAILED DESCRIPTION

[0022] The utility model will be further described in detail in combination with the drawings.

[0023] Example one, in combination with the drawingsFigure 1 A multifunctional fixing clamp for shell abrasive tools comprises moving seats 1 capable of moving towards each other, which are identical in structure and opposite in direction. Specifically, each moving seat 1 is provided with a threaded hole 2 penetrating through, and a double-threaded rotating rod is threadedly connected between the moving seats 1, capable of moving towards or away from each other. In actual use, the double-threaded rotating rod can be installed on a processing base, and the moving seats 1 can be adjusted in spacing by driving of a motor, so as to realize clamping.

[0024] The drawings will be described below Figure 1 , 2 , 3, an inclined extrusion assembly; located on the front of the moving seat 1, comprising an electric push rod 3, and a plane clamp is rotationally arranged at the output end of the electric push rod 3. Specifically, the output end of the electric push rod 3 is provided with a connecting plate, and the lower end of a connecting arm 5 is U-shaped, capable of being sleeved outside the connecting plate and rotationally connected with the connecting plate, so that the plane clamp can change the inclination angle when the electric push rod 3 is operated.

[0025] In addition, the plane clamp comprises a clamping panel 4 and the connecting arm 5, and the front of the moving seat 1 is provided with a support 6 capable of being connected with the connecting arm 5. The support 6 comprises a T-shaped mounting piece 7, and a support rod 8 is connected to the mounting piece 7. The end of the support rod 8 is U-shaped and rotationally connected with the connecting arm 5.

[0026] In the above structure, the support 6 plays a supporting and limiting role on the clamping panel 4, so that the clamping panel 4 can stably adjust the inclination angle and be uniformly stressed.

[0027] The drawings will be described below Figure 1 , 4 , 5, a round pipe fixing assembly; comprising a base plate 9 capable of being detachably connected with the clamping panel 4, and the base plate 9 is connected with the clamping panel 4 through bolts.
