Lock-bar thrust tester

The utility model discloses a thrust tester for a lock tongue, which is used for testing thrust of the lock tongue and comprises a base plate, and a lock body fixing plate used for simulating installation and fixation of a lock body on a door body and the lock tongue is vertically installed on the front side of the base plate. The rear side of the base plate is provided with a pressure gauge for monitoring the thrust value of each extending distance of the spring bolt; a displacement adjusting assembly is arranged on the lower side of the pressure gauge and used for adjusting the placing position of the pressure gauge in the linear direction relative to the spring bolt so as to control different extending distances of the spring bolt relative to the pressure gauge. Different extending distances of the pressure gauge relative to the spring bolt are controlled through the displacement adjusting assembly, thrust value monitoring of the pressure gauge on all extending distances of the spring bolt is achieved, the
