It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only. The terms "left", "right", "front" and "rear" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the indicated device or component must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 2 and 3, the utility model discloses a tooling clamp, which comprises a support 10, a pressing member 20 for pressing a workpiece, and a locking handle 30 for fixing the pressing member 20 and the workpiece; the support 10 is provided with a first groove 110 for placing a workpiece, a side wall 1101 of the first groove is provided with a plurality of through holes 1110, and the locking handle 30 fixes the pressing member 20 and the workpiece through the through holes 1110.

Specifically, the support may have a rectangular parallelepiped shape, and the length of the support 10 may be set according to the length of the machined part. The depth of the first groove is the same as the height of the processing surface of the workpiece to be processed, namely the processing surface of the workpiece to be processed, which is positioned in the first groove, is flush with the upper surface of the support or is slightly lower than the upper surface of the support, so that the workpiece can be processed and produced conveniently.

Further, a third groove 1103 for collecting the waste is provided at the bottom of the first groove, and the width of the third groove should be smaller than the width of the bottom of the first groove. Through setting up the third recess in order to collect clearance sweeps.

Second grooves 1120 penetrating through the side walls (1101, 1102) of the first grooves are formed between every two adjacent through holes, and the side walls of the first grooves are divided into a plurality of independent blocks by the second grooves. As shown in fig. 3, a second groove 11201 penetrating through the sidewalls (1101, 1102) of the first groove is opened between the adjacent through holes 11101, 11102, and the sidewalls (1101, 1102) of the first groove are divided into independent blocks 11011, 11021 by the second groove 11201. The cross section of the square 11011 is convex, and the cross section of the square 11011 is designed to be convex so as to be matched with a pressing piece, and a workpiece can be better fixed and positioned.
