Based on the embodiments of 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.

[0020] See also Figure 1-3 The utility model provides a technical solution: an intraoral three-dimensional scanning device, including a scanning head body 1, a mounting seat 2 is sleeved on the scanning head body 1, a slide groove 3 is opened on the outer wall ring of the mounting seat 2, a slide seat 4 is slidably sleeved in the slide groove 3, a moving mechanism for adjusting the slide seat 4 to slide in the slide groove 3 is arranged in the mounting seat 2, a rotating groove 9 is opened on the slide seat 4, a rotating ring 10 is rotatably sleeved in the rotating groove 9, a handle 11 is fixedly provided on the outer wall of the rotating ring 10, and the handle 11 is vertically arranged to the scanning head body 1, a card groove 14 is opened on the inner wall of the rotating groove 9, and a plurality of cards are evenly arranged along the inner wall of the rotating groove 9, a card block groove 16 is opened on the inner wall of the rotating ring 10, and a card block 15 for inserting into the card groove 14 to limit the rotation of the rotating ring 10 is arranged in the card block groove 16.

[0021] Specifically, the moving mechanism includes a screw rod 5 and a knob 7. The screw rod 5 is rotatably arranged on the inner wall of the slide groove 3 and passes through a mounting seat 2 on one side. One end of the screw rod 5 located outside the mounting seat 2 is coaxially fixedly connected with the knob 7. A threaded hole 6 for the screw rod 5 to pass through and threadedly connected to the screw rod 5 is opened on the slide seat 4. The screw rod 5 is rotated to rotate. The threaded connection between the screw rod 5 and the threaded hole 6 on the slide seat 4 allows the slide seat 4 to slide in the slide groove 3, thereby adjusting the position of the handle 11. The self-locking effect of the screw rod 5 and the threaded hole 6 can keep the slide seat 4 fixed, thereby keeping the handle 11 fixed.

[0022] Specifically, a limit column 8 rotatably connected to the mounting base 2 is fixedly provided coaxially at one end of the screw rod 5 away from the knob 7. The diameter of the limit column 8 is larger than the diameter of the screw rod 5. The setting of the limit column 8 prevents the screw rod 5 from axial movement.

[0023] Specifically, a stabilizing rod 12 is fixedly provided on the inner wall of the slide groove 3 on the side away from the screw rod 5, and a through groove 13 is opened on the slide seat 4 for the stabilizing rod 12 to pass through and is slidably connected to the stabilizing rod 12. The action of the stabilizing rod 12 and the through groove 13 improves the sliding stability of the slide seat 4.

[0024] Specifically, a block spring 17 for driving the block 15 to slide is fixedly provided at the bottom of the block groove 16. The block spring 17 is fixedly connected to one end of the block 15 located in the block groove 16. The end of the block 15 located outside the block groove 16 is an arc surface and fits tightly with the slot 14. The block 15 is inserted into the slot 14 to limit the swivel 10 to prevent the swivel 10 from rotating freely in the swivel groove 9. When the angle of the handle 11 needs to be adjusted, the mounting base 2 is fixed with one hand, and then the swivel 10 is turned forcefully. The block 1 The arc surface of 5 is acted upon by the inner wall of the card slot 14 so that the card block 15 compresses the card block spring 17 to slide out of the card slot 14 and slide into the card block slot 16. The swivel 10 loses its limit and can rotate in the rotating slot 9 until the card block 15 is directly opposite to the next card slot 14. Under the elastic force of the card block spring 17, the card block 15 is clamped into the card slot 14 to limit the swivel 10 again. This is repeated, so that the swivel 10 can be rotated on the rotating slot 9 and fixed at different angles, so that the angle of the handle 11 can be adjusted easily.

[0025] Specifically, a rubber sleeve is tightly fitted on the handle 11 to increase the friction between the doctor's hand and the handle 11 and improve the grip. The mounting base 2 is fixed to the scanning head body 1 by screws. The scanning head body 1 is provided with screw holes, and the screws can be used to facilitate the disassembly and assembly between the mounting base 2 and the scanning head body 1.

[0026] A specific application example of this embodiment is:

[0027] When the device is in use, the mounting base 2 can be fixed on the scanning head body 1 by screws, and the screw rod 5 can be driven to rotate by turning the knob 7. The screw rod 5 is threadedly connected with the threaded hole 6 on the slide seat 4, so that the slide seat 4 slides in the slide groove 3, thereby adjusting the position of the handle 11. The mounting base 2 is fixed by one hand, and then the rotating ring 10 is turned forcefully. The arc surface of the clamping block 15 is subjected to the force of the inner wall of the clamping groove 14 to make the clamping block 15 compress the clamping block spring 17 to slide out of the clamping groove 14 and slide into the clamping block groove 16. The rotating ring 10 loses the limit and can rotate in the rotating groove 9 until the clamping block 15 is directly opposite to the next clamping groove 14. Under the elastic force of the clamping block spring 17, the clamping block 15 is clamped into the clamping groove 14 to limit the rotating ring 10 again. This is repeated, thereby adjusting the angle of the handle 11, so that the handle 11 is adjusted to a comfortable gripping position for the doctor, and three-dimensional scanning in the oral cavity can be performed, which can prevent the doctor from slipping in the hand of the scanning head body 1 when directly gripping the scanning head body 1 for oral scanning, affecting the scanning work.
