In the same way, when carrying out the withdrawal force test, reverse promotion catch bar 432, the second removes seat 300 reverse movement, dynamometer 500 on the second removes seat 300 can stimulate first removal seat 200 reverse movement, the ammeter on the first removal seat 200 that will drive is separated with the ammeter plug connector on the fixed plate 800, and the setting of standing groove can carry on spacingly to the removal of ammeter plug connector, make the ammeter plug connector have a maximum sliding distance, when the lateral wall butt of ammeter plug connector and standing groove, the ammeter is extracted from the ammeter plug connector, the display screen department on the dynamometer 500 can show that ammeter and ammeter plug connector extract the momentary withdrawal force.

In one possible implementation, the mounting seat 100 has a rectangular plate shape, and the bottom of the mounting seat 100 is provided with a plurality of supporting columns for supporting the mounting seat 100.

Having described embodiments of the present application, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
