When the first adjusting screw 301 is rotated, the two first clamping plates 302 are driven to move. Since the internal thread directions of the two first clamping plates 302 are opposite, the distance between the two first clamping plates 302 can be adjusted, which makes it convenient to use samples of different thicknesses and improves the application range of the device.

[0023] A fixing frame 4 is welded and fixed on the top of the base 1, and a lifting device 5 is arranged on the inner wall of the fixing frame 4. The lifting device 5 comprises a first motor 501, and the output shaft of the first motor 501 is inserted into the inner wall of the fixing frame 4 and is rotatably connected with the inner wall of the fixing frame 4.

At the same time, the second clamping plate 602 and the sample clamped between the second clamping plate 602 are driven to move, so that the sample can be stretched, and the peeling strength is detected by using the detection device, which is convenient for users to operate and improves the convenience of the device.

[0024] A second fixing device 6 is provided on the inner wall of the lifting block 503, and the second fixing device 6 includes a second adjusting screw 601, and the second adjusting screw 601 is inserted into the inner wall of the lifting block 503 and is rotatably connected to the inner wall of the lifting block 503.
