[0024] 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.

[0025] See also Figure 1-8 The utility model provides a technical solution: a dental reciprocating forward and reverse polishing head, comprising a handpiece tube 1, a low-speed handpiece motor 2 is threadedly connected to the handpiece tube 1, a low-speed handpiece outgoing water straightener 3 is installed on the top of the low-speed handpiece motor 2, a polishing cup shell 4 is arranged on the top of the low-speed handpiece outgoing water straightener 3, a rotating groove 14 is opened on the front side of the polishing cup shell 4, a polishing head 5 is rotatably connected to the rotating groove 14, a fixing component for fixing the polishing cup shell 4 is installed on the top of the low-speed handpiece outgoing water straightener 3, and a reciprocating forward and reverse component for driving the polishing head 5 to reciprocate forward and reverse on the rotating groove 14 is installed inside the polishing cup shell 4.

[0026] When the dental reciprocating forward and reverse polishing head is in use, high-pressure gas flows into the low-speed handpiece motor 2 through the handpiece tube 1, causing the low-speed handpiece motor 2 to rotate in one direction. The low-speed handpiece motor 2 can also be manually selected to rotate forward or reverse. A low-speed handpiece outgoing water straightener 3 is installed on the low-speed handpiece motor 2, and the polishing cup shell 4 is fixed by a fixing component installed on the top of the low-speed handpiece outgoing water straightener 3. The reciprocating forward and reverse components installed inside the polishing cup shell 4 drive the polishing head 5 to reciprocate forward and reverse on the rotating groove 14, thereby reducing the heat generated by the friction of the unidirectional rotation of the polishing head 5, and also avoiding the problem of hair being drawn into the polishing head 5 when processing the animal's mouth, causing the polishing head 5 to be stuck.

[0027] The fixing assembly comprises a rotating rod 9, which is rotatably connected to the top of the low-speed mobile phone outgoing water straightener 3. The top of the rotating rod 9 is fixedly connected to a connecting column 10, and a limiting annular groove 11 is provided on the outer surface of the connecting column 10.

[0028] A positioning block 7 is fixedly connected to the top front side of the low-speed mobile phone outgoing water straightener 3, and a positioning groove 6 is opened on the bottom front side of the polishing cup shell 4.

[0029] A slot 21 is provided on the front side of the polishing cup housing 4 at the limiting ring groove 11 , and a buckle 8 is clamped on the slot 21 . The upper and lower sides of the rear of the buckle 8 are respectively in contact with the upper and lower inner walls of the limiting ring groove 11 .

[0030] When the fixing component is in use, it is positioned by the positioning block 7 at the top of the low-speed handpiece external water outlet straight machine 3 and the positioning groove 6 at the bottom of the polishing cup housing 4. A clamping groove 21 is formed on the polishing cup housing 4 and a limiting ring groove 11 is formed on the outer surface of the connecting column 10. The buckle 8 is clamped on the clamping groove 21, and the upper and lower inner walls of the rear part of the buckle 8 are abutted against the limiting ring groove 11. Since the connecting column 10 is rotatably installed on the low-speed handpiece external water outlet straight machine 3 through the rotating rod 9, the fixing of the polishing cup housing 4 on the low-speed handpiece external water outlet straight machine 3 is completed. When it is necessary to disassemble the polishing cup housing 4, only the buckle 8 needs to be removed to quickly complete the disassembly.

[0031] The reciprocating forward and reverse rotation component includes a connecting plate 15. The connecting plate 15 is fixedly connected to the top of the connecting column 10. A convex block 16 and a plug rod 17 are fixedly connected to the top of the connecting plate 15. A reciprocating rotating block 12 is arranged above the convex block 16. The front side of the reciprocating rotating block 12 is fixedly connected to the rear side of the polishing head 5. A groove 18 is formed on the bottom side of the reciprocating rotating block 12. A slot 19 is formed through the reciprocating rotating block 12, and the slot 19 communicates with the groove 18.

[0032] A limiting circular groove 13 is formed on the rear side of the reciprocating rotating block 12, and a limiting rod 20 is fixedly connected to the rear inner wall of the rotating groove 14.

[0033] When the reciprocating forward and reverse rotation component is in use, the connecting plate 15 is rotated through the rotating rod 9. Since the connecting plate 15 is circular and the convex block 16 on the top of the connecting plate 15 is on one side, the convex block 16 is driven to rotate on the connecting plate 15. The plug rod 17 on the connecting plate 15 is inserted into the slot 19 formed through the reciprocating rotating block 12, and the convex block 16 abuts against the groove 18 on the bottom side of the reciprocating rotating block 12. Since the groove 18 is high in the middle and low on both sides, the convex block 16 is low in the middle and high on both sides, and the limiting circular groove 13 on the rear side of the reciprocating rotating block 12 cooperates with the limiting rod 20 on the rear side of the rotating groove 14. Therefore, when the convex block 16 rotates to the left, it presses against the groove 18, causing the reciprocating rotating block 12 rotatably connected to the rotating groove 14 to rotate to the right. When the convex block 16 rotates to the right, the reciprocating rotating block 12 rotates to the left. Finally, the reciprocating rotating block 12 reciprocates forward and reversely on the rotating groove 14. Since the upper side of the slot 19 is fan-shaped, the plug rod 17 will not get stuck with the reciprocating rotating block 12 during the reciprocating forward and reverse rotation process.

[0034] Working principle: When the dental reciprocating forward and reverse polishing head is used, high-pressure gas flows into the low-speed handpiece motor 2 through the handpiece tube 1, so that the low-speed handpiece motor 2 rotates in one direction. The low-speed handpiece motor 2 can also be manually selected to rotate forward or reverse. A low-speed handpiece outgoing water straightener 3 is installed on the low-speed handpiece motor 2, and the positioning block 7 on the top of the low-speed handpiece outgoing water straightener 3 is matched with the positioning groove 6 at the bottom of the polishing cup shell 4 for positioning, and a card slot 21 is provided on the polishing cup shell 4 and a limit ring groove 11 is provided on the outer surface of the connecting column 10 , the buckle 8 is connected to the card slot 21, and the rear part of the buckle 8 abuts against the upper and lower inner walls of the limiting ring groove 11. Since the connecting column 10 is rotatably installed on the low-speed mobile phone outgoing water straightener 3 through the rotating rod 9, the polishing cup shell 4 is fixed on the low-speed mobile phone outgoing water straightener 3. When the polishing cup shell 4 needs to be disassembled, it can be quickly completed by removing the buckle 8, and then the connecting plate 15 is rotated by the rotating rod 9. Since the connecting plate 15 is circular, the protrusion 16 on the top of the connecting plate 15 is on one side, thereby driving the protrusion 16 on the connecting plate The plate 15 is rotated, the insertion rod 17 on the connecting plate 15 is inserted into the slot 19 through which the reciprocating rotating block 12 is opened, and the protrusion 16 abuts against the groove 18 on the bottom side of the reciprocating rotating block 12. Since the groove 18 is high on both sides and low in the middle, the protrusion 16 is low on both sides and high in the middle, and the limiting circular groove 13 on the rear side of the reciprocating rotating block 12 cooperates with the limiting rod 20 on the rear side of the rotating groove 14, so when the protrusion 16 rotates to the left, the groove 18 is squeezed, so that the reciprocating rotating block 12 connected to the rotating groove 14 rotates to the right. When the reciprocating rotating block 16 rotates to the right, the reciprocating rotating block 12 rotates to the left, and finally the reciprocating rotating block 12 reciprocates forward and reverse on the rotating groove 14. Since the upper side of the slot 19 is fan-shaped, the insertion rod 17 will not get stuck in the reciprocating rotating block 12 during the reciprocating forward and reverse process, and then the driving polishing head 5 installed on the front side of the reciprocating rotating block 12 reciprocates forward and reverse on the rotating groove 14, thereby reducing the heat generated by the unidirectional rotation friction of the polishing head 5, and also avoiding the problem of hair being rolled into the polishing head 5 when processing the animal's mouth, causing the polishing head 5 to get stuck.
