Torsional angle and pressure detection device for windshield wiper arm

The utility model provides a torsional angle and pressure detection device for a windshield wiper arm, which can simultaneously measure a torsional angle and the pressure of the windshield wiper arm. The torsional angle and pressure detection device comprises a seat body, wherein the seat body is vertically provided with a scale plate with torsional angle scales, the scale plate is rotationally provided with a windshield wiper arm holder convexly provided with a pointer pointing to the torsional angle scales, a weightometer is arranged at the bottom of the seat body, and a working end of the weightometer is fixedly connected with the bottom of the seat body. When the torsional angle and pressure detection device is used, the end part of the windshield wiper arm is suspended on a windshield wiper arm holder and drives the windshield wiper arm holder to rotate, and the rotation angle is reflected on the scale plate through the pointer; simultaneously, the end part of the windshield wiper arm is pressed on the windshield wiper arm holder, and the weightometer at the bottom of the seat body displays a corresponding number value according to the born pressure so that the torsional angle and the pressure of the windshield wiper arm can be synchronously detected. The torsional angle and pressure detection device can be used for detecting the numerical values of the torsional angle and the pressure of the windshield wiper arm in one step; the operation is simplified, the time is saved, and the work efficiency is greatly improved.
