[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 The utility model provides an embodiment: a friction tester, comprising a body 1, a bottom plate 2 is fixedly connected to the lower surface of the body 1, a placement plate 3 is slidably connected to the outer wall of the body 1, a limiting hole 4 is provided inside the placement plate 3, a fixing block 1 5 is fixedly connected to the lower surface of the placement plate 3, a fixing block 2 6 is fixedly connected to the opposite side of the fixing block 1 5, a bidirectional screw rod 7 is rotatably connected inside the fixing block 2 6, one end of the bidirectional screw rod 7 is rotatably connected to the inside of the fixing block 2 6, and the other end of the bidirectional screw rod 7 is fixedly connected to The adjusting block 20, the outer wall of the bidirectional screw rod 7 is threadedly connected with a left-right symmetrical threaded sleeve 8, one side of the outer wall of the two threaded sleeves 8 is rotatably connected with a connecting plate 9, the outer wall of the connecting plate 9 is rotatably connected with a fixing plate 10, the outer wall of the fixing plate 10 is slidably connected to the inner wall of the limiting hole 4, and the upper surface of the fixing plate 10 is provided with a clamping assembly 11; the clamping assembly 11 includes a clamping block 1101, the lower surface of the clamping block 1101 is fixedly connected to the upper surface of the fixing plate 10, and the inside of the clamping block 1101 is slidably connected with a buffer plate 1102;

[0033] Specifically, first, place the tested product on the upper surface of the placement plate 3. Next, by rotating the adjustment block 20, the clamping device can be easily adjusted to adapt to products of different sizes. The design of the adjustment block 20 takes into account the ergonomic principle, making the operation more convenient and comfortable. The rotation of the adjustment block 20 is carried out by rotating the bidirectional screw 7 inside the fixed block 2 6. As the bidirectional screw 7 rotates, the connecting plate 9 on the outer wall of the threaded sleeve 8 will also rotate accordingly. The rotation of the connecting plate 9 is achieved through a precise transmission mechanism, which ensures the stability and accuracy of the rotation. The rotation of the connecting plate 9 further drives the fixed plate 10 to slide on the inner wall of the limiting hole 4. The design of the limiting hole 4 takes into account the size range and clamping accuracy requirements of the product, ensuring that the fixed plate 10 always remains stable during the sliding process. The fixed plate 10 is made of lightweight and high-strength material, which not only ensures the clamping force, but also reduces the overall weight of the device. Finally, the buffer plate 1102 inside the clamping block 1101 is driven by the fixed plate 10 to clamp and fix the product. The buffer plate 1102 is made of elastic material, which can effectively buffer the impact force during the clamping process and protect the product surface from damage. The clamping block 1101 and the buffer plate 1102 are detachably connected to facilitate replacement and maintenance.

[0034] Reference Figure 3 , Figure 4 , a mounting tube 12 is fixedly connected to the upper surface of the bottom plate 2, and a sliding rod 13 is slidably connected inside the mounting tube 12; a handle 14 is fixedly connected to one end of the sliding rod 13, and a block 16 is fixedly connected to the other end of the sliding rod 13; a spring 15 is sleeved on the outer wall of the sliding rod 13, one end of the spring 15 is fixedly connected to one side of the inner wall of the mounting tube 12, and the other end of the spring 15 is fixedly connected to one side of the outer wall of the block 16; an insertion rod 17 is fixedly connected to the surface of the placement plate 3, and the insertion rod 17 is slidably connected to the inner wall of the mounting tube 12; a protrusion 19 is fixedly connected to the lower surface of the insertion rod 17, and the protrusion 19 is slidably connected to the inside of the mounting tube 12; a groove 18 is provided inside the insertion rod 17, and the groove 18 is engaged with the block 16;

[0035] Specifically, when the placement plate 3 needs to be disassembled, the operator only needs to pull a specific handle 14, which is tightly connected to the sliding rod 13. By pulling the handle 14, the sliding rod 13 will drive the block 16 to retract into the interior of the mounting tube 12. In this process, the block 16 will squeeze the spring 15 in contact with it, causing it to deform. When the block 16 is completely retracted into the mounting tube 12, the operator can easily lift the placement plate 3. Since the insertion rod 17 is no longer restricted by the block 16 at this time, it will smoothly break away from the interior of the mounting tube 12, thereby realizing the rapid disassembly of the placement plate 3. During the installation process, the reaction force of the spring 15 will push the block 16 to re-engage on the inner wall of the groove 18 of the mounting tube 12. This engaging structure is not only stable and reliable, but also can ensure the stability of the placement plate 3 during use.

[0036] Working principle: When the friction tester is needed to test the product, the product is placed on the upper surface of the placement plate 3. At this time, the adjusting block 20 is rotated to drive the bidirectional screw 7 to rotate inside the fixed block 6. The rotation of the bidirectional screw 7 drives the connecting plate 9 on the outer wall of the threaded sleeve 8 to rotate. The rotation of the connecting plate 9 drives the fixed plate 10 to slide on the inner wall of the limiting hole 4. At this time, the buffer plate 1102 inside the clamping block 1101 is driven by the fixed plate 10 to clamp and fix the product, thereby achieving the effect of facilitating rapid clamping and fixing according to the size of the product.

[0037] Secondly, when the clamping device needs maintenance, the handle 14 is pulled to make the sliding rod 13 drive the block 16 to retract into the installation tube 12. The movement of the block 16 achieves the effect of squeezing the spring 15. The placement plate 3 is lifted to drive the insertion rod 17 out of the installation tube 12, thereby achieving the effect of quick disassembly. During installation, the reaction force of the spring 15 pushes the block 16 to engage with the inner wall of the groove 18, thereby fixing the placement plate 3.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
