An elastic rubber block 18 is fixedly connected to the top of the inner wall of the fixed barrel 17, and the top of the detection cone 503 contacts the bottom of the elastic rubber block 18.

[0031] In this embodiment: By contacting the elastic rubber block 18 inside the fixed barrel 17, the detection cone 503 can have a space for moving up and down, achieving the effect of facilitating the detection cone 503 to have an upward movement space.

[0032] As a technical optimization solution of the present utility model, a limiting groove 12 is provided inside the fixing plate 2.

[0034] As a technical optimization solution of the present utility model, support blocks 7 are fixedly connected to both sides of the top of the sliding plate 501, and the placement box 6 is fixedly connected between the opposite sides of the two support blocks 7.

[0035] In this embodiment: By fixedly connecting the placement box 6 between the opposite sides of the two support blocks 7, the support blocks 7 can support the placement box 6, achieving the effect of supporting the placement box 6.

[0036] As a technical optimization solution of the present utility model, a connecting rod 13 is provided on the front side of the slider 502. The rear side of the connecting rod 13 is fixedly connected to the front side of the slider 502, and a pull ring 14 is fixedly connected to the surface of the connecting rod 13.

[0037] In this embodiment: By holding the pull ring 14 by hand, the slider 502 can be easily pulled, achieving the effect of facilitating the pulling of the slider 502.

[0038] As a technical optimization solution of the utility model, a clamping plate 8 is fixedly connected to the rear side of the top of the bottom plate 1, a fixing strip 15 is fixedly connected to the front side of the top of the bottom plate 1, a rotating rod 4 is arranged on the front side of the fixing strip 15, the rear side of the rotating rod 4 passes through the fixing strip 15 and extends to the rear side of the fixing strip 15, the surface of the rotating rod 4 is in threaded connection with the inside of the fixing strip 15, and a clamping block 16 is rotatably connected to the rear side of the rotating rod 4.

[0039] In this embodiment: By rotating the rotating rod 4, the clamping block 16 moves backward. At this time, the clamping block 16 and the clamping plate 8 can clamp and limit the touch screen, achieving the effect of conveniently clamping the touch screen.

[0040] As a technical optimization solution of the utility model, legs 9 are fixedly connected to the four corners of the bottom of the bottom plate 1, and handles 10 are fixedly connected to both sides of the bottom plate 1.

[0041] In this embodiment: By holding the handle 10, the bottom plate 1 can be conveniently moved to a stable place. At this time, the legs 9 at the bottom of the bottom plate 1 will stably support the bottom plate 1, achieving the effects of conveniently moving the bottom plate 1 and stably supporting the bottom plate 1.

[0042] Working principle: First, hold the handle 10 and move the bottom plate 1 to a stable place. At this time, the legs 9 at the bottom of the bottom plate 1 will stably support the bottom plate 1. Then, place the touch screen to be detected at the bottom of the detection cone 503. Then, rotate the rotating rod 4. Due to the threaded connection between the rotating rod 4 and the fixed strip 15, when the rotating rod 4 rotates, the rotating rod 4 can move backward, driving the clamping block 16 to move backward, so that the clamping plate 8 and the clamping block 16 clamp the touch screen. The rotating rod 4 is rotatably connected to the clamping block 16, so that the rotating rod 4 can rotate. Then, move the sliding plate 501 downward until the bottom of the detection cone 503 contacts the top of the touch screen. Then, according to the required force applied to the top of the touch screen, place counterweight blocks in the placement box 6 to press down, and then hold the pull ring 14 and pull it, which can drive the connecting rod 13 and the pulling block to move back and forth. At this time, the detection cone 503 can detect the scratch resistance of the touch screen. It should be noted that the hardness of the detection cones 503 gradually increases from left to right. When the detection cone 503 with low hardness cannot scratch the touch screen, due to the downward pressure of the counterweight block, the detection cone 503 with low hardness can squeeze the elastic rubber block 18, causing the detection cone 503 with low hardness to move upward. At this time, the detection cone 503 with high hardness can continue to test the scratch resistance of the touch screen. By pulling the pull ring 14, five sliders 502 and five detection cones 503 with different hardnesses can be driven to move, so as to simultaneously detect the scratch resistance of the touch screen in five levels, avoiding the problem that when most existing touch screens are detected for scratch resistance after production, different hardness detection cones 503 are used to scratch the touch screen separately to judge the scratch resistance of the touch screen, which is not convenient to control different hardness detection cones 503 to test the touch screen simultaneously, affecting the detection efficiency of the touch screen scratch resistance.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
