Referring to FIGS. 1 to 3 , a clamp for quick adjustment includes a base 1 and a connecting column 2, the base 1 is connected with the lower end of the connecting column 2, and the upper end of the connecting column 2 is connected with a support plate 3, A cylinder 4 is installed on the top surface of the base 1, and a push plate 5 is installed on the push rod of the cylinder 4. The push plate 5 is hinged with a connecting rod 7 through the first rotating shaft 6, and the upper end of the connecting rod 7 passes through. The second rotating shaft 8 is hinged with a claw body 9, a rotating shaft 10 is installed in the middle of the claw body 9, and a hollow part 11 is arranged in the middle of the support plate 3, and the edge of the hollow part 11 is regularly surrounded by a number of installation parts 12, so The upper end of the claw body 9 passes through the mounting portion 12, and is hinged with the support plate 3 through the rotating shaft 10; the push plate 5 is driven or retracted by the air cylinder 4 and through the connecting rod 7. Conducting force, so that the claw body 9 rotates around the rotating shaft 10 to realize the clamping or loosening of the claw body 9, so as to satisfy the same driving effect as the crank-rocker mechanism.

Both sides of the mounting portion 12 are provided with mounting holes 13 penetrating the support plate 3 laterally, the rotating shaft 10 is mounted in the mounting holes 13 , and the bottom surface of the support plate 3 corresponds to the opening position of the mounting hole 13 . A fixing screw hole 14 is provided, the fixing screw hole 14 passes through the mounting hole 13, and the fixing screw hole 14 is threadedly connected with a fixing screw 15; when assembling, first insert the rotating shaft 10 into the mounting hole 13 Then, pass through the claw body 9 to hinge the claw body 9 on the support plate 3, and finally tighten the fixing screw 15 in the fixing screw hole 14; The technical effect of the axial displacement of the rotating shaft 10 is that both ends of the connecting column 2 are internally provided with threads; A second fixing bolt 17 is threadedly connected to the lower end through the base 1; this design structure is firm and reliable.
