A ball bearing 18 is rotatably connected to the inner side wall of the hinge seat 17 through a shaft. A second electric telescopic rod 19 is fixedly connected to the inner side wall of the grinding device housing 2. One end of the telescopic rod of the second electric telescopic rod 19 is rotatably connected to the connecting rod 20.
[0032] The conveying module includes a spring telescopic rod 21 and a third motor 26. The spring telescopic rod 21 is rotatably connected to the inner bottom wall of the grinding device housing 2. A bracket 22 is fixedly connected to the telescopic end of the spring telescopic rod 21. A second motor 23 is fixedly connected to the outer surface of the bracket 22. A drive roller 24 is fixedly connected to the output shaft of the second motor 23. The third motor 26 is fixedly connected to the inner side wall of the grinding device housing 2.

A worm 28 is provided in the middle of the rotating shaft 27, and a worm gear 25 is provided on the outer surface of the spring telescopic rod 21.
[0033] Specifically, handle 1 is fixedly connected to the housing 2 of the grinding device. The grinding module is hinged to the upper surface of the housing via control cover 7. The control knob 8 is threaded to the housing to achieve opening and closing. The clamping plate 15 of the fixed module is slidably connected to the inner wall of the housing via a slide groove. The second electric telescopic rod 19 drives the clamping plate 15 to move via connecting rod 20. The spring telescopic rod 21 of the conveying module is rotatably connected to the bottom wall of the housing. The worm gear 28 and worm wheel 25 are connected to the spring telescopic rod 21. The drive roller 24 is fixed to the telescopic end of the spring telescopic rod 21 via bracket 22. Holding handle 1, the device is brought close to the billiard cue. The parameters are set via adjustment button 4. The second electric... The telescopic rod 19 retracts, driving the connecting rod 20 to open the clamping plate 15. After the billiard cue is inserted, the electric telescopic rod extends, and the ball bearing 18 is fixed tightly against the cue body. The first motor 9 drives the grinding disc 14 to rotate through the gearbox 10. The first electric telescopic rod 11 adjusts the grinding depth. At the same time, the third motor 26 adjusts the tilt angle of the spring telescopic rod 21 through the worm gear 28 and worm wheel 25. The second motor 23 drives the roller 24 to rotate and move the billiard cue, achieving full-circumference grinding. The overall structure is compact, and the handle 1 is designed in accordance with ergonomics. The weight is concentrated in the middle of the shell, and it can be operated with one hand when carried. It is smaller in size than traditional devices and meets the needs of on-site maintenance.
[0034] Two clamping plates 15 are symmetrically arranged on the inner wall of the outer shell via a sliding rail. A rotating ring 16 is nested inside the clamping plates 15. A hinge seat 17 is fixed to the inner wall of the rotating ring 16 and connected to the ball bearing 18 via a shaft. The two ends of the second electric telescopic rod 19 are rotatably connected to the outer shell and the connecting rod 20 respectively. The other end of the connecting rod 20 is hinged to the clamping plate 15, forming a parallelogram transmission structure. When it is necessary to fix billiard cues of different diameters, the second electric telescopic rod 19 is activated. Its telescopic rod extends and pushes the connecting rod 20, causing the two clamping plates 15 to slide in opposite directions along the sliding rail. When the rotating ring 16 moves with the clamping plates 15, the ball bearing 18 adapts to the curved surface of the cue through the hinge seat 17. The surface of the ball bearing 18 is coated with silicone to increase friction, ensuring that billiard cues of different thicknesses can be stably clamped, solving the cumbersome problem of manually replacing pads in traditional clamps.
[0035] The third motor 26 is fixed to the inner wall of the housing, and its output shaft is connected to the rotating shaft 27. The worm gear 28 is fixed to the middle of the rotating shaft 27 and meshes with the worm wheel 25 on the outer surface of the spring telescopic rod 21. The upper end of the spring telescopic rod 21 is fixed to the second motor 23 through the bracket 22. The drive roller 24 is coaxially connected to the output shaft of the second motor 23. When adjusting the grinding position, the third motor 26 drives the worm gear 28 to rotate in both directions. The worm wheel 25 causes the spring telescopic rod 21 to rotate around the bottom fulcrum, and the tilt angle of the drive roller 24 changes. For example, when the tilt angle is 0°, the billiard cue only rotates and does not move. When the tilt angle changes, it can be transported left and right. At the same time, the speed of the second motor 23 can be adjusted within the range by adjusting the button 4. In conjunction with the speed of the grinding disc 14, the mode switching between coarse grinding (low speed and large tilt angle) and fine grinding (high speed and small tilt angle) can be realized, and the grinding efficiency is improved compared with the traditional device.
[0036] In summary, when using the entire device: hold the handle 1 and adjust the grinding distance and grinding speed using the adjustment button 4 and display 3. After activation, the second electric telescopic rod 19 retracts, driving the two clamping plates 15 to move towards the center via two connecting rods 20. Then, the billiard cue is inserted from the inside of the two sets of clamping plates 15. Upon startup, the second electric telescopic rod 19 extends, causing the two clamping plates 15 to shift relative to each other via the connecting rods 20. At this point, multiple balls 18 on the inner side of the rotating ring 16 press against the outer surface of the billiard cue, thus fixing it in place. When the first motor 9 rotates, it drives the rotating cylinder 13 and grinding disc 14 to rotate via the gearbox 10, thereby grinding the outer surface of the billiard cue. The arrangement of the first electric telescopic rod 11 and connecting plate 12 allows for… The rotating cylinder 13 and the grinding disc 14 move up and down, thereby adjusting the grinding depth and force. At the same time, the spring telescopic rod 21 drives the bracket 22 and the drive roller 24 to lift upward, so that the inner side of the drive roller 24 presses against the lower surface of the billiard cue. When the second motor 23 drives the drive roller 24 to rotate, it drives the billiard cue to move left and right. When the third motor 26 drives the rotating shaft 27 to rotate, the spring telescopic rod 21 is driven to rotate through the transmission action of the worm gear 28 and the worm wheel 25, adjusting the tilt angle. At this time, the billiard cue can rotate and move left and right at the same time. The larger the tilt angle, the higher the speed of the billiard cue's left and right movement. The clamping plate 15 and the rotating ring 16 are set up so that after the billiard cue is clamped by the two rotating rings 16, it can cooperate with the conveying module to make the billiard cue move left and right and rotate.
[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
