Clamp of high-frequency reciprocating measuring machine

The utility model discloses a clamp of a high-frequency reciprocating measuring machine. The clamp comprises the high-frequency reciprocating measuring machine and a clamp body. Through cooperative use of the high-frequency reciprocating measuring machine, the clamp, the positioning block, the shell, the supporting hole, the supporting rod, the clamping rod, the clamping groove, the fixing groove, the positioning assembly and the control assembly, a user drives the positioning rod to leave the interior of the positioning groove through cooperation between the control assembly and the positioning assembly; and then the position of the positioning block can be adjusted along the track of the supporting hole, so that the bottom of the positioning block is in close contact with the top of an article to be clamped for fixation, and then positioning is performed through the positioning assembly, thereby solving the problem that the existing high-frequency reciprocating tester needs to use a clamp to position the ar
