Embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below:

Embodiment 1:

According to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises pedestal 1 and pull and push dynamometer 2, offer first groove 11 in the pedestal 1, be placed with sliding seat 3 in first groove 11, offer second groove 31 on the sliding seat 3, pull and push dynamometer 2 is installed in second groove 31, and second groove, 31 edges are provided with " U " type notch, and the measuring staff head of pull and push dynamometer 2 " U " type notch thus ejects.

As Fig. 1, Fig. 2 and shown in Figure 3, test supporting seat 12 is set on the pedestal 1, this test supporting seat 12 be " L " type sheet metal, and the one side is installed on the upper surface of pedestal 1 by screw retention, and the measuring staff head of its opposite side surface and pull and push dynamometer 2 is vertical and should offer groove bar 121 in the middle part of the surface.
