[0032] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] See also Figure 5 In one embodiment of the present application, an adjustment tool 100 is provided, which can be used in dental treatment or in other scenarios. The adjustment tool 100 can clamp the second workpiece 210 and rotate the first workpiece 220 relative to the second workpiece 210. The adjustment tool 100 clamps the second workpiece 210, connects and drives the first workpiece 220 to rotate, so that the rotating member rotates in the second workpiece 210, thereby rotating the first workpiece 220 relative to the second workpiece. The adjustment tool 100 is applied to an annular forming sheet structure 200, which includes a shell, a rotating member and a forming sheet 230. The first workpiece 220 is a rotating member, and the second workpiece 210 is a shell rotatably sleeved on the outer periphery of the first workpiece 220. By clamping the shell, connecting and driving the rotating member to rotate relative to the shell, the forming sheet 230 is gradually wound around the rotating member to adjust the size of the ring surrounded by the forming sheet 230, so that the forming sheet 230 can be adapted to the patient's teeth.

[0034] Compared with the existing screwdriver, such an adjustment tool 100 has a clamping function, which can not only clamp the shell but also drive the rotating part to rotate, making it convenient for users to use and operate.

[0035] Please continue reading Figure 1The adjusting tool 100 includes a handle 10, an operating member 20 and a clamping member 30. The handle 10 is used to install the operating member 20 and the clamping member 30 and protect the operating member 20. The operating member 20 is used to drive the first workpiece 220 to rotate. The clamping member 30 is used to clamp the second housing so that when the operating member 20 drives the first workpiece 220 to rotate, the first workpiece 220 rotates relative to the second workpiece 210.

[0036] Please continue reading Figure 2 The handle 10 includes a gripping portion 11 and a curved tube 12. The gripping portion 11 is connected to the curved tube 12. The operating member 20 includes a rotating portion 21, an extending portion 22 and a cutter head 23. One end of the extending portion 22 is fixedly connected to the rotating portion 21, and the other end of the extending portion 22 is connected to the cutter head 23. The gripping portion 11 includes a cavity 111, and the curved tube 12 is provided with a channel 1201, and the cavity 111 is connected to the channel 1201. The rotating portion 21 is provided in the cavity 111, and the extending portion 22 is passed through the channel 1201. The gripping portion 11 also includes an opening 112, and the opening 112 is connected to the cavity 111. The user can move the rotating portion 21 relative to the gripping portion 11 toward the curved tube 12 along the first direction a through the opening 112, so that the cutter head 23 passes through an end of the curved tube 12 away from the gripping portion 11 and is connected to the first workpiece 220. The user can also use the opening 112 to make the rotating portion 21 drive the extending portion 22 and the cutting head 23 to rotate, so that the first workpiece 220 rotates relative to the second workpiece 210 around the axis b.

[0037] The clamping member 30 is disposed at one end of the curved tube 12 away from the holding portion 11 , and is used to clamp the second workpiece 210 to fix the second workpiece 210 , prevent the second workpiece 210 from rotating with the first workpiece 220 , and fix the positions of the first workpiece 220 and the second workpiece 210 by fixing the second workpiece 210 .

[0038] In the above design, the clamping member 30 clamps the second workpiece 210, and the user holds the gripping portion 11. The user moves the rotating portion 21 in the cavity 111 along the first direction a toward the curved tube 12 through the opening 112, so that the extension portion 22 drives the cutter head 23 to move, and the cutter head 23 extends out of the handle 10 and connects to the first workpiece 220. The user rotates the rotating portion 21 in the cavity 111 through the opening 112, so that the extension portion 22 drives the cutter head 23 to rotate around the axis b, and the cutter head 23 rotates the first workpiece 220 relative to the second workpiece 210 around the axis b, thereby adjusting the rotation of the first workpiece 220 relative to the second workpiece 210. The adjustment tool 100 can clamp the second workpiece 210 and enable the first workpiece 220 to rotate relative to the second workpiece 210.

[0039] In some embodiments, the cutter head 23 can be kept extending out of the curved pipe 12 without external force, thereby keeping the cutter head 23 connected to the first workpiece 220. The adjustment tool 100 also includes an elastic member 40. Figure 4, the elastic member 40 is disposed in the cavity 111. The two ends of the elastic member 40 respectively abut against the rotating portion 21 and the bottom wall of the cavity 111 to apply a force to the convex ring 211 to move toward the channel 1201. It can be understood that in other embodiments, the elastic member 40 can also be omitted.

[0040] As an illustrative example, the elastic member 40 is a spring.

[0041] In some embodiments, see Figures 2 to 5 The rotating part 21 includes a convex ring 211 and a connecting rod 212. The connecting rod 212 and the extension part 22 are respectively arranged at opposite ends of the convex ring 211. When the cutter head 23 is connected to the first workpiece 220, the convex ring 211 corresponds to the opening 112, so that the convex ring 211 can be rotated through the opening 112. The convex ring 211 can facilitate the operation of the user, and it is convenient for the user to drive the convex ring 211 to drive the extension part 22 to rotate or move the extension part 22 toward the curved pipe 12. The connecting rod 212 extends away from the extension part 22 along the first direction a, and the elastic member 40 is sleeved on the connecting rod 212, and the two ends of the elastic member 40 abut against the bottom wall of the cavity 111 and the convex ring 211. It is convenient to install the elastic member 40, and can prevent the elastic member 40 from shaking in the cavity 111.

[0042] In some embodiments, there is a gap between the outer periphery of the convex ring 211 and the inner wall of the grip portion 11. When the gap is smaller, it is easier to operate the convex ring 211, so that the convex ring 211 rotates in the cavity 111. It can be understood that if the gap is zero, the convex ring 211 and the inner wall of the grip portion 11 will rub against each other, which is not conducive to the rotation of the convex ring 211 in the cavity 111.

[0043] In some embodiments, see Figure 1 and Figure 2 The openings 112 are two oppositely arranged, so that the user can operate the convex ring 211 through the openings 112 .

[0044] In some embodiments, see Figure 1 and Figure 2 The outer periphery of the convex ring 211 is provided with anti-slip grooves to increase the friction between the user and the convex ring 211, making it easier for the user to operate.

[0045] In some embodiments, see Figures 2 to 5 , the cutter head 23 is a cross screwdriver head 23. In other embodiments, the cutter head 23 may also be a hexagonal screwdriver head 23. It is understandable that the cutter head 23 may also be other shapes that can be connected to the first workpiece 220 and can drive the first workpiece 220 to rotate. The first workpiece 220 is provided with a groove matching the cutter head 23, so that the cutter head 23 can drive the first workpiece 220 to rotate.

[0046] In some embodiments, see Figures 3 to 5, the curved pipe 12 also includes a connecting portion 1231. The connecting portion 1231 is connected to one end of the curved pipe 12 away from the gripping portion 11. The clamping member 30 includes a matching portion 31 and a chuck 32, and the matching portion 31 is connected to the chuck 32. Among them, the curved pipe 12 and the clamping member 30 are connected through the connecting portion 1231 and the matching portion 31. The chuck 32 is used to clamp the second workpiece 210, and the matching portion 31 is sleeved on the connecting portion 1231, so that the tool head 23 passes through the curved pipe 12 and the matching portion 31 and connects the first workpiece 220. It can be understood that the matching portion 31 can be fixedly sleeved on the connecting portion 1231. The matching portion 31 can also be rotatably sleeved on the connecting portion 1231, so that the orientation of the chuck 32 can be changed, which facilitates the chuck 32 to clamp the first workpiece 220.

[0047] In some embodiments, the peripheral side of the connecting portion 1231 is provided with an external thread, the matching portion 31 is cylindrical, the inner wall of the matching portion 31 is provided with an internal thread, and the external thread and the internal thread cooperate to make the clamping member 30 threadedly connected to the elbow 12. The elbow 12 and the clamping member 30 are threadedly connected through the connecting portion 1231 and the matching portion 31, so that the clamping member 30 can be connected to the elbow 12, and the orientation of the clamp 32 can be changed to clamp the second workpiece 210.

[0048] In some embodiments, see Figure 1 , Figure 2 and Figure 5 The chuck 32 includes a bending portion 321 and a clamping portion 322. The bending portion 321 is connected to the connecting portion 1231, and the bending portion 321 is connected to the clamping portion 322. The bending portion 321 is bent toward the side away from the curved tube 12, so that the clamping portion 322 corresponds to the channel 1201, and the clamping portion 322 is arranged below the channel 1201. The clamping portion 322 has a clamping groove 3221, and the clamping groove 3221 has a notch 3222. The second workpiece 210 enters the clamping groove 3221 through the notch 3222. The side wall of the clamping groove 3221 clamps the second workpiece 210, and the tool head 23 passes through the curved tube 12 and the clamping groove 3221 to connect the first workpiece 220. As an exemplary distance, the clamping groove is a U-shaped groove. The bending portion 321 is a U-shaped sheet metal part.

[0049] By changing the orientation of the clamping head 32 , the orientation of the notch 3222 of the engaging groove 3221 can be changed to change the position of the second workpiece 210 .

[0050] In order to facilitate user operation and use, the curved tube 12 is bent downward. Figure 1 and Figure 2The curved tube 12 includes a first section 121, an arc section 122 and a second section 123. The first section 121 is connected to the grip portion 11, and the first section 121 extends in a direction parallel to the first direction a. The first section 121 and the second section 123 are respectively connected to opposite ends of the arc section 122, and the arc section 122 is bent downward to form an arc. The second section 123 extends along the axis b, and the connecting portion 1231 is provided at one end of the second section 123 away from the arc section 122. The first direction a forms an angle α with the axis b, and the angle α is any preset angle between 90° and 180°. The curvature of the arc section 122 is between 60° and 90°, and the larger the curvature of the arc section 122, the greater the degree of curvature of the arc section 122. It can be understood that when the angle α is preset to a smaller angle, the degree of curvature of the arc section 122 that bends downward is greater. When the angle α is preset to a larger angle, the arc segment 122 bends downward to a smaller degree. It should be noted that when the angle α is preset to 180 degrees, the first direction a is parallel to the axis b, and the rotating portion 21, the extension portion 22 and the cutter head 23 are connected in a straight line at this time. The extension portion 22, the cutter head 23 and the first workpiece 220 are all rotated around the axis b by the rotating portion 21 rotating around the axis b. After the user clamps the second workpiece 210 with the clamping member 30, the user can hold the handle 10 and move the annular forming sheet 230 structure, so that the circular ring of the forming sheet 230 is sleeved on the patient's teeth, and drive the rotating portion 21 to rotate in the cavity 111, so that the cutter head 23 drives the first workpiece 220 to rotate relative to the second workpiece 210 around the axis b, thereby adjusting the size of the circular ring to adapt to the patient's teeth.

[0051] In some embodiments, the angle α is preset to 108°. When in use, the axis b is parallel to the vertical direction, and the angle α formed by the first direction a and the axis b is beneficial for the user to hold the grip portion 11, and is also beneficial for driving the convex ring 211 to rotate while holding the grip portion 11, or driving the convex ring 211 to move in a direction parallel to the first direction a, which can improve the user's comfort and facilitate user operation.

[0052] In some embodiments, the extension portion 22 can be bent freely and has elasticity to transmit the torque of the rotating portion 21 to the cutter head 23. As an exemplary example, the extension portion 22 is a flexible shaft.

[0053] The flexible shaft is a shaft with very low rigidity, elasticity and free bending transmission, which is used to connect the rotating member extending parallel to the first direction a and the cutter head 23 arranged along the axis b, and can transmit the torque of the rotating part 21 to make the cutter head 23 rotate around the axis b.

[0054] When in use, the grip portion 11 is held by hand, and the convex ring 211 is driven to move along the first direction a toward one end away from the channel 1201 through the opening 112, so that the cutter head 23 enters the channel 1201. Then, the housing is clamped to the clamping groove through the notch 3222, and the convex ring 211 is released. Under the action of the elastic member 40, the convex ring 211 moves along the first direction a toward one end of the channel 1201, so that the cutter head 23 passes through the elbow 12 and the clamping groove and is connected to the first workpiece 220. Finally, the convex ring 211 is driven to rotate in the cavity 111 through the opening 112, so that the cutter head 23 and the first workpiece 220 rotate around the axis b relative to the second workpiece 210.

[0055] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
