[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown in the figure, the present invention provides a scratch-resistant mechanism for a diamond roller, including a roller body 1 and a protective cover 2. A receiving shell 3 is placed on the top of the roller body 1 and is bolted to the top of the roller body 1. A cavity 4 is opened inside the receiving shell 3, and a limiting component 5 is provided inside the cavity 4. The protective cover 2 is provided below the roller body 1, and a sleeve rod 6 is fixedly connected to the middle of the upper surface of the protective cover 2. The roller body 1 and the sleeve rod 6 cooperate with each other.

[0024] refer to Figure 2 The limiting component 5 includes a rotating disk 501, a limiting rod 502, a limiting frame 503, and a slider 504. The rotating disk 501 is rotatably connected to the middle of the lower surface of the cavity 4. The top of the rotating disk 501 in the four directions of front, back, left, and right is provided with a stroke groove 7. The four corners of the bottom of the cavity 4 are fixedly connected to the limiting frame 503. The limiting rod 502 is slidably connected inside the limiting frame 503. The top of the limiting rod 502 near the rotating disk 501 is fixedly connected to the slider 504. The slider 504 is slidably connected inside the stroke groove 7. The end of the limiting rod 502 away from the slider 504 passes through and extends out of the surface of the receiving shell 3.

[0025] By adopting the above solution, the limit component 5 can be set to achieve precise movement and stable limiting of the limit rod 502, ensuring the firm fixation of the roller body 1 and the protective cover 2, while improving the reliability and ease of operation of the device.

[0026] refer to Figure 3 The protective cover 2 has four through holes 8 on its surface. The through holes 8 are evenly distributed on the surface of the protective cover 2. The position of each through hole 8 corresponds to the position of each limiting rod 502. The limiting rod 502 is used in conjunction with the through holes 8.

[0027] By adopting the above solution, through holes 8 can be set to achieve precise fixation between the roller body 1 and the protective cover 2, thereby enhancing the stability of the device, simplifying operation, and improving the protective effect.

[0028] refer to Figure 1 The top of the rotating disk 501 is fixedly connected to a pull handle 9, the top of the housing 3 is provided with a guide groove 10, the bottom of the pull handle 9 is slidably connected to the inside of the guide groove 10, the top of the pull handle 9 is fixedly connected to a fixing block 11, and the inside of the fixing block 11 is provided with a receiving groove 12.

[0029] By adopting the above solution, by setting the pull handle 9 and the guide groove 10, the rotary disk 501 can be conveniently operated and accurately positioned, thereby improving the reliability and operating efficiency of the device.

[0030] refer to Figure 5 A spring 13 is fixedly connected to the top of the receiving groove 12, and a fixing rod 14 is fixedly connected to the bottom of the spring 13. The bottom of the fixing rod 14 extends through and out of the bottom of the pull handle 9. A pull rod 15 is fixedly connected to the top of the fixing rod 14. The top of the pull rod 15 extends through and out of the top of the fixing block 11. Fixing holes 16 are provided on both the left and right sides of the bottom of the guide groove 10. The fixing holes 16 are used in conjunction with the fixing rod 14.

[0031] By adopting the above solution, by setting spring 13, pull rod 15 and fixing hole 16, the fixing rod 14 can be automatically reset and stably locked, ensuring that the pull handle 9 is quickly fixed after operation, thus improving the convenience and reliability of the device.

[0032] refer to Figure 5 Limiting grooves 17 are provided on both the front and rear sides of the receiving groove 12, and the front and rear sides of the top of the fixing rod 14 are slidably connected to the limiting grooves 17.

[0033] By adopting the above solution, the movement direction of the fixed rod 14 can be restricted by setting the limiting groove 17, ensuring that the fixed rod 14 remains stable during sliding, avoiding deviation or jamming, thereby improving the operating accuracy and reliability of the device.

[0034] refer to Figure 3 and Figure 4 The top of the protective cover 2 is fixedly connected with four positioning rods 18, which are equidistantly distributed on the top of the protective cover 2. The bottom of the roller body 1 is provided with four positioning grooves 19, which are used in conjunction with the positioning rods 18.

[0035] By adopting the above solution, the positioning rod 18 and positioning groove 19 can be set to achieve precise positioning and stable connection between the protective cover 2 and the roller body 1, ensuring the alignment and fixation between the two, and improving the overall stability and ease of installation of the device.

[0036] The working principle of this utility model:

[0037] In use, first, the middle part of the roller body 1 is fitted onto the surface of the sleeve rod 6. Then, the positioning rod 18 is inserted into the corresponding positioning groove 19. After the roller body 1 is placed, the pull rod 15 can be pulled upwards. The pull rod 15 drives the fixing rod 14 to move upwards along the limiting groove 17. After the fixing rod 14 is removed from the fixing hole 16, the pull handle 9 is rotated along the guide groove 10. When the pull handle 9 moves to the far right, the pull rod 15 is released. The spring 13 will reset the fixing rod 14, allowing it to re-insert into the fixing hole 16. At this time, the pull handle 9 will be locked. Then, when the pull handle 9 is rotated, it will drive the rotating disk 501 to rotate. Since the limiting rod 502 is slidably connected to the inside of the limiting frame 503, the limiting rod 502 can only move along the direction of the limiting frame 503. When the rotating disk 501 rotates, the slider 504 will drive the limiting rod 502 to move due to the stroke groove 7. After the rotating disk 501 rotates a certain angle, the limiting rod 502 will extend out of the surface of the receiving shell 3. Due to the positioning groove 19 and the positioning rod 18, the position of the through hole 8 corresponds to the position of the limiting rod 502. When the limiting rod 502 is inserted into the through hole 8, the roller body 1 is fixed together with the protective cover 2, thereby effectively protecting the roller body 1.

[0038] In summary, this anti-scratch mechanism for diamond rollers, through the coordinated use of roller body 1, protective cover 2, receiving shell 3, cavity 4, limiting component 5, sleeve rod 6, stroke groove 7, through hole 8, pull handle 9, guide groove 10, fixing block 11, receiving groove 12, spring 13, fixing rod 14, pull rod 15, fixing hole 16, limiting groove 17, positioning rod 18, and positioning groove 19, solves the problems of complex connection between roller body and protective cover in existing equipment, inaccurate positioning, and cumbersome operation, which lead to unstable fixing effect, easy loosening or falling off of the protective cover, and inability to effectively protect the roller body, thus affecting the service life and safety of the equipment.
