Description

Technical Field

[0002] The mouse pad is an auxiliary tool placed on the desktop to place the mouse and provide a smooth surface for mouse movement. The mouse pad is usually made of rubber, cloth, plastic or metal materials, which can effectively protect the desktop from scratches and provide comfort and precision when the mouse is operated. When the mouse pad is produced and shipped, it is necessary to take corresponding friction resistance test treatment for the mouse pad shipped, so as to avoid that the friction of some mouse pads after shipping does not meet the qualified standards, which affects the quality and durability in the later period. At present, there are still some problems in the use of the mouse pad friction resistance test device. The stability of the mouse pad is particularly important in the friction resistance test stage. When the mouse pad shakes during the friction resistance test, it is easy to cause the mouse pad to be out of the test range, resulting in test failure. The mouse pad out of the test range needs to be put back into the test area, which affects the corresponding friction resistance test efficiency. At the same time, the specifications of the mouse pad are different. When the friction resistance test device cannot be applied to mouse pads of different specifications and sizes, the test of the mouse pad friction resistance test device is limited, which reduces the universal effect of the mouse pad friction resistance test device and directly affects the use and test efficiency of the mouse pad friction resistance test device.

[0003] Therefore, it is necessary to develop a mouse pad friction resistance testing device. Utility Model Content
