Disclosed is a simple device for testing a pulling resistance force. The simple device includes a counterforce frame, the bottom part of which is provided with an expansion bolt used for fixing. The top end of the expansion bolt is provided with an indicating gauge. The counterforce frame is provided with a support at the front and back respectively. A sleeper beam is arranged between the two supports. A jack and a pressure sensor are arranged on the sleeper beam. The jack and the pressure sensor are located in the counterforce frame. The simple device for testing the pulling resistance force is simple in structure and convenient to use. Materials can be used locally and purchase of a large quantity of testing devices is not needed so that testing is easy to implement. The simple device is not only capable of testing force values which can be tested by instruments in the market, but also capable of enabling the maximum pulling resistance force and corresponding displacement of an anchoring part during work to be observed through a force-displacement curve chart so that whether work demands are met is judged.
