Gridding cloth section elongation detection device

The utility model discloses a gridding cloth section elongation detection device which comprises a moving seat, a rectangular mounting frame is fixed at the top of the moving seat, a transverse plate is slidably mounted on the inner side of the rectangular mounting frame, and a driving mechanism used for driving the transverse plate to move vertically is arranged on the moving seat. A tension sensor is fixed to the bottom of the transverse plate, an upper fixing block is fixed to the force measuring end of the tension sensor, a lower fixing block is fixed to the inner wall of the bottom of the transverse plate, and fixing mechanisms are fixed to the lower fixing block and the upper fixing block; and a laser displacement sensor of which the measuring end faces the transverse plate is fixed on the inner wall of the top of the rectangular mounting frame. The whole device can be used for detecting the elongation of the section of the gridding cloth, the stretching length and the stretching strength can be observe
