[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, the present invention provides a car muffler hook abrasive, including a transmission 1, a grinding table 2 and a grinding disc 3. A blocking cover 4 is movably connected to the top of the grinding table 2 via a shaft pin. A movable groove 5 is provided on the top of the blocking cover 4. The output end of the transmission 1 passes through the movable groove 5 into the interior of the blocking cover 4 and is fixedly connected to the top of the grinding disc 3. An adjustment hole 6 is provided on the left side of the blocking cover 4. An adjustment component 7 is fixedly connected to the back of the transmission 1. A collection component 8 is slidably connected to the bottom of the inner wall of the grinding table 2. A clamping adjustment mechanism 9 is provided on the left side of the blocking cover 4.

[0021] refer to Figure 3 The adjusting assembly 7 includes a screw 71, the top of the front of the screw 71 is fixedly connected to the top of the back of the transmission 1, and a screw sleeve 72 is threadedly connected to the bottom of the surface of the screw 71.

[0022] As a technical optimization of this utility model, by setting the adjustment component 7, when it is necessary to adjust the distance between the grinding disc 3 and the hook, the user can directly rotate the screw sleeve 72. By utilizing the threaded connection between the screw sleeve 72 and the screw rod 71, the screw sleeve 72 rotates and drives the screw rod 71 to move up and down for adjustment. Then, the screw rod 71 will drive the transmission mechanism 1 to move the grinding disc 3 up and down for adjustment, thereby conveniently adjusting the distance between the grinding disc 3 and the hook.

[0023] refer to Figure 1 and Figure 2 The collection component 8 includes a collection box 81, the two sides of which are slidably connected to the two sides of the inner wall of the polishing table 2, and a collection groove 82 is provided on the top of the polishing table 2.

[0024] As a technical optimization of this utility model, by setting up a collection component 8, the debris that is concentrated and blocked in the blocking cover 4 during the grinding of the hook can fall into the inside of the collection box 81 through the collection groove 82, and thus be collected by the collection box 81. When there is too much debris collected in the collection box 81, the user can move the collection box 81 to the front and pull it out to pour out or recycle the debris in the collection box 81.

[0025] refer to Figure 2 The clamping and adjusting mechanism 9 includes a rotating groove 91, which is located on the left side of the blocking cover 4. A rotating ring 92 is slidably connected inside the rotating groove 91. A stud 93 is threadedly connected to the back of the rotating ring 92. The front of the stud 93 extends into the interior of the rotating ring 92 and is movably connected to a clamping ring 94 via a pin.

[0026] As a technical optimization of this utility model, by setting up a clamping and adjusting mechanism 9, when the user inserts one end of the hook into the adjusting hole 6, that end of the hook will be inserted into the rotating ring 92. Then, by rotating the stud 93, the stud 93 is rotated and moved to the front by the threaded connection between the stud 93 and the rotating ring 92. Then, the stud 93 will push the clamping ring 94 to clamp the corresponding end of the hook. Then, by using the sliding cooperation between the rotating ring 92 and the rotating groove 91, the end of the hook can be rotated to adjust the grinding angle of the hook while being clamped.

[0027] refer to Figure 2 and Figure 3 Limiting grooves 10 are provided on both sides of the top of the blocking cover 4. Limiting blocks 11 are slidably connected inside the limiting grooves 10. The top of the rear limiting groove 10 is movably connected to the bottom of the screw sleeve 72 through a shaft pin.

[0028] As a technical optimization of this utility model, by setting a limiting groove 10 and a limiting block 11, the limiting groove 10 and the limiting block 11 can limit the transmission machine 1 in the front and back, so that the transmission machine 1 can also be adjusted left and right when it is turned on, thereby increasing the grinding range and improving the stability of the transmission machine 1 during left and right movement.

[0029] refer to Figure 1 A stabilizing telescopic rod 12 is fixedly connected to the top of the front side of the transmission machine 1, and the bottom of the stabilizing telescopic rod 12 is fixedly connected to the top of the front limiting block 11.

[0030] As a technical optimization of this utility model, by setting a stabilizing telescopic rod 12, the transmission machine 1 can be rotated and limited, thereby improving the stability of the transmission machine 1 when it drives the grinding disc 3 to rotate. Furthermore, by utilizing the telescopic effect of the stabilizing telescopic rod 12, the transmission machine 1 is stabilized without affecting its vertical adjustment.

[0031] refer to Figure 1 and Figure 3 A limit frame 13 is fixedly connected to the rear side of the bottom of the inner wall of the grinding table 2, and an anti-slip groove is provided on the surface of the screw sleeve 72.

[0032] As a technical optimization of this utility model, by setting a limiting frame 13, the maximum movement space of the collection box 81 can be limited, so that the collection box 81 can quickly correspond to the collection slot 82 when placed, and avoid the collection box 81 from deviating when placed, causing some debris to fall directly to the bottom of the inner wall of the grinding table 2.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to grind the hook, the user first opens the blocking cover 4, then inserts one end of the hook into the adjustment hole 6, and then closes the blocking cover 4. The user then holds one end of the hook through the adjustment hole 6 and starts the transmission machine 1, which drives the grinding disc 3 to rotate. The bottom of the grinding disc 3 will then contact the hook and grind it. Even if the hook being ground inside the blocking cover 4 is thrown off, it can be blocked by the blocking cover 4. The debris generated when the hook is being ground can also be blocked by the blocking cover 4. The debris will rotate and spread outwards and will not fly out from the movable groove 5, thus enabling the debris to be collected and processed.

[0034] If it is necessary to adjust the distance between the grinding disc 3 and the hook, the user can directly rotate the screw sleeve 72. By utilizing the threaded connection between the screw sleeve 72 and the screw rod 71, the screw sleeve 72 rotates and drives the screw rod 71 to move up and down for adjustment. Then, the screw rod 71 will drive the grinding disc 3 to move up and down for adjustment via the transmission mechanism 1, thereby conveniently adjusting the distance between the grinding disc 3 and the hook.

[0035] During the grinding of the hook, the debris that is concentrated and blocked in the shield 4 can fall into the collection box 81 through the collection groove 82 and be collected by the collection box 81. When there is too much debris in the collection box 81, the user can move the collection box 81 to the front and pull it out to pour out or recycle the debris in the collection box 81.

[0036] When the user inserts one end of the hook into the adjustment hole 6, that end of the hook will be inserted into the rotating ring 92. Then, the stud 93 is rotated, and the threaded connection between the stud 93 and the rotating ring 92 causes the stud 93 to rotate and move forward. Then, the stud 93 will push the clamping ring 94 to clamp the corresponding end of the hook. Then, by utilizing the sliding cooperation between the rotating ring 92 and the rotating groove 91, the end of the hook can be rotated to adjust the grinding angle of the hook while it is being clamped.

[0037] In summary, this automotive muffler hook grinding tool, by incorporating a baffle 4, prevents the hook from being flung off during grinding, even if it is within the baffle 4. Furthermore, the debris generated during grinding is also blocked by the baffle 4. This solves the problem of the hook being flung off due to rotational force during hand-held grinding, which is dangerous and makes the grinding process dangerous. Additionally, it addresses the issue of metal shavings flying haphazardly and being difficult to collect and process.
