Frequency measurement clamp for medium and small gas turbine blades

The invention provides a frequency measurement clamp for medium and small gas turbine blades, which can solve the problem that the blade roots are easy to damage when the medium and small gas turbine blades use the existing frequency measurement clamp to detect the frequency. The clamp comprises a clamp body and a side face positioning block and further comprises a jacking block, a wheel groove which is matched with the blade root tooth shape of the medium and small gas turbine blade and is through left and right is machined in the top of the clamp body, and the side face positioning block is located on the left side or the right side of the wheel groove and fixedly connected with the clamp body. A jacking block mounting hole coaxially communicated with the wheel groove is further machined in the position, below the wheel groove, of the clamp body, the lower end of the jacking block is inserted into the jacking block mounting hole in a sliding fit mode, the upper end of the jacking block extends into the whee
