[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range of protection of the utility model.

[0017] As Figure 1 Shown, a three-edge quick woodworking clamp, including clamp pad 1, button 2, main body 3, cover plate 4, screw rod 5, knob 6, spring 7 and movable nut 8, the main body 3 is C type structure, both ends and the middle position of main body 3 are equipped with threaded hole, and the threaded hole is installed with screw rod 5, and the both ends of screw rod 5 are equipped with knob 6 and clamp pad 1 respectively, by rotating knob 6, screw rod 5 is rotated in threaded hole and drives clamp pad 1 to move forward and backward, and the main body 3 is equipped with locking structure for locking screw rod 5, and the locking structure is composed of button 2, spring 7 and movable nut 8, and the screw thread of nut 8 is separated or engaged with the screw thread of screw rod 5 by the action of button 2 and spring 7.

[0018] Working principle is as follows:

[0019] Push button 2 forward to make the screw thread of movable nut 8 separate with the screw thread of screw rod 5, and screw rod 5 can advance or retreat quickly, open clamp pad 9 to the maximum position, align the plane of three clamp pads to the surface of workpiece, push screw rod 5 forward, rotate knob 6 clockwise, three clamp pads clamp workpiece, complete the whole clamping process.

[0020] After completing clamping work, rotate knob 6 counterclockwise, exit three clamp pads, and take clamp from the workpiece.

[0021] The main body 3 adopts aluminum alloy material with high strength, and the left and right sides adopt quick clamping structure. Three clamping pads 1 in three directions can clamp three surfaces of the workpiece plane.

[0022] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
