[0020] The existing device cannot ensure the stability of the container when fixing the food container. If the force is too large or too small, the container may be deformed and the clamping may be unstable, which will affect the accuracy of the result.

[0021] In view of this, an anti-scratch testing device with good fixing effect is provided. Through the cooperation between a round rod, a pressure plate and a buffer spring, the device uses the elastic deformation of the buffer spring to fix the container, thereby ensuring stability while avoiding deformation of the container, improving the fixing effect, and solving the problem that the existing device cannot ensure the stability of the container when fixing the food container, and the container will be deformed and the clamping will be unstable due to excessive or insufficient force, thereby affecting the accuracy of the result.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: Figure 1 , 2As shown in Figure 4, a scratch resistance test device with good fixing effect comprises a bent plate 19, a cutter head 10 is arranged on one side of the bent plate 19, a positioning mechanism is arranged on the inner side of the bent plate 19, the positioning mechanism comprises a back plate 11, a transverse plate 12, a round rod 13, a pressure plate 14, a buffer spring 15 and a bottom plate 17, one side of the back plate 11 is fixedly connected to the inner side of the bent plate 19, one side of the back plate 11 is fixedly connected to the transverse plate 12, a through hole of the transverse plate 12 is movably connected to the round rod 13, the bottom of the round rod 13 is fixedly connected to the pressure plate 14, the outer side of the round rod 13 is movably connected to the buffer spring 15, the two ends of the buffer spring 15 are respectively fixedly connected to the bottom of the transverse plate 12 and the top of the pressure plate 14, after the pressure plate 14 contacts the container, the container is fixed by the elastic deformation of the buffer spring 15, and the bottom slide groove on one side of the back plate 11 is movably connected to the bottom plate 17;

[0024] In the specific implementation process, it is worth pointing out that, through the cooperation between the pressing plate 14, the buffer spring 15 and the bottom plate 17, the device uses the elastic deformation of the buffer spring 15 to fix the container, thereby ensuring stability while avoiding deformation of the container, improving the fixing effect, and solving the problem that the existing device cannot ensure the stability of the container when fixing the food container, and the container will be deformed and the clamping will be unstable due to excessive or insufficient force, thereby affecting the accuracy of the result;

[0025] Furthermore, the inner side of the bottom plate 17 is threadedly connected to a screw rod 16, and the outer side of the screw rod 16 is rotatably connected to a plate body 18 through a bearing. The screw rod 16 can rotate through the bearing, and the top of the plate body 18 is fixedly connected to the bottom of the back plate 11;

[0026] In the specific implementation process, it is worth pointing out that when the screw 16 is rotated, the bottom plate 17 below can be driven to move upward to fix the container;

[0027] Specifically, when using the anti-scratch testing device with good fixing effect, the user places the canned container between the pressure plate 14 and the bottom plate 17, and then rotates the screw 16. When the screw 16 is rotated, the bottom plate 17 below can be driven to move upward to fix the container. At this time, the container is fixed by relying on the elastic deformation of the buffer spring 15, which ensures the stability of the container and avoids deformation.

[0028] Embodiment 2: By Figure 1-3 It can be seen that the groove on one side of the curved plate 19 is movably connected to the plug plate 2, and the plug plate 2 can move in the groove on one side of the curved plate 19. A straight plate 3 is fixedly connected to one end of the plug plate 2. A slide groove 4 is processed on the top of the straight plate 3. A trapezoidal block 5 is slidably clamped on the inner side of the slide groove 4. A vertical cylinder 7 is fixedly connected to the top of the trapezoidal block 5. A curved rod 9 is movably connected to the inner side of the vertical cylinder 7. The curved rod 9 can move inside the vertical cylinder 7. A through hole on one side of the curved rod 9 is movably connected to the outer side of the cutter head 10, and the cutter head 10 can move in the through hole of the curved rod 9.

[0029] In the specific implementation process, it is worth pointing out that the user can pull the trapezoidal block 5 and the vertical cylinder 7 to drive the cutter head 10 to scratch the container, and the telescopic curved rod 9 can change the scratching position;

[0030] Furthermore, a first bolt 6 is pressed against the top of the plug plate 2, and the outer side of the first bolt 6 is threadedly connected to the inner side of the bent plate 19, and the front side of the vertical tube 7 is threadedly connected to a second bolt 8 pressed against the outer wall of the bent rod 9;

[0031] In the specific implementation process, it is worth pointing out that the first bolt 6 is used to position the lateral extension position of the cutter head 10 after being tightened, and the second bolt 8 is used to position the height of the cutter head 10 after being tightened;

[0032] Furthermore, a guide block 20 is fixedly connected to one end of the cutter head 10, and one side of the guide block 20 is fixedly connected to one end of the inner side of the curved rod 9 through a compression spring 1. The outer wall of the guide block 20 is slidably engaged with the inner side of the curved rod 9, and the guide block 20 can only move laterally inside the curved rod 9.

[0033] In the specific implementation process, it is worth pointing out that when the cutter head 10 contacts the container, the compression spring 1 is driven to contract, thereby avoiding hard contact between the cutter head 10 and the container surface, wherein the elastic force of the compression spring 1 is not limited and can be selected as needed;

[0034] Specifically, based on the above-mentioned embodiment 1, the scratch position can be adjusted as needed through the cooperation between the slide groove 4, the trapezoidal block 5 and the first bolt 6. At the same time, multiple sets of fixed structures are set to facilitate synchronous measurement, thereby improving work efficiency.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions.
