Description

Technical Field

[0001] The utility model relates to the technical field of orthodontic pliers, in particular to an orthodontic pliers capable of measuring torque angle. Background Art

[0002] Orthodontic pliers are a common instrument in the dental department. Their main function is to clamp and fix the arch wire to facilitate orthodontic doctors to perform tooth correction. During the correction process, orthodontists can use orthodontic pliers to bend the arch wire to fix the arch wire on the teeth and correct the teeth.

[0003] For example, the orthodontic pliers disclosed in the patent with patent number CN216675960U, although the orthodontic pliers are arranged by the main pin shaft and the cross arrangement of the first pliers head and the second pliers head, when the second pliers handle and the first pliers handle control the opening and closing of the two pliers heads, the force on the two pliers heads can be dispersed to the main pin shaft, thereby reducing the force on the connection between the pliers handle and the pliers head, avoiding deformation of the connection, and improving the service life of the pliers handle; however, when the orthodontic pliers are used to bend the arch wire, the operator needs to use two orthodontic pliers to clamp the arch wire and rotate them relative to each other. During this process, the operator needs to hold the second pliers handle and the first pliers handle all the time to control the two pliers heads to close all the time, which makes it inconvenient for the operator to use the orthodontic pliers to bend the arch wire, so it needs to be improved.

[0023] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0024] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0025] Combined with attachment Figure 1-Figure 5 In this embodiment, an orthodontic pliers capable of measuring torque angle includes a pliers body, which includes a first pliers handle 100 and a second pliers handle 110 hinged to each other, and first pliers beaks 200 and second pliers beaks 210 that fit together are respectively provided at one end of the first pliers handle 100 and the second pliers handle 110, and a locking assembly is provided on the first pliers handle 100 and the second pliers handle 110 for locking the first pliers beak 200 and the second pliers beak 210 when they are closed.

[0026] When this embodiment is actually used, Figure 1 As shown, when the operator uses the orthodontic pliers to bend the arch wire 140, two orthodontic pliers need to be used in conjunction with each other. The two orthodontic pliers are placed opposite to each other, and the corresponding first pliers beak 200 and second pliers beak 210 are used to clamp and fix the arch wire 140. The two orthodontic pliers are fitted together. At this time, the two orthodontic pliers are rotated relative to each other around the arch wire 140 to achieve bending of the arch wire 140.

[0027] In actual use, a corresponding mounting hole is provided between the first beak 200 and the second beak 210, and a rotating shaft 170 is rotatably provided in the mounting hole. The rotating shaft 170 is used to realize the rotational connection between the first beak 200 and the second beak 210, that is, to realize the opening and closing of the first beak 200 and the second beak 210. The arch wire 140 is placed between the first beak 200 and the second beak 210, and the first handle 100 and the second handle 110 are gripped and clamped. When the first handle 100 and the second handle 110 are brought close to each other, the first beak 200 and the second beak 210 can be driven to close, thereby clamping the arch wire 140, so that the arch wire 140 can be fixed.

[0028] The first beak 200 and the second beak 210 are provided with protrusions 300 opposite to each other, and a connecting portion 310 is provided on the side wall of one end of the protrusion 300. The first handle 100 and the second handle 110 are respectively connected to the corresponding connecting portions 310. The rotating shaft 170 is rotatably mounted on the connecting portion 310, thereby preferably forming a pliers body.

[0029] In actual use, in order to enable the first beak 200 and the second beak 210 to better clamp the arch wire 140, the first beak 200 and the second beak 210 are provided with limiting grooves 220 adapted to the arch wire 140 on the opposing inner side walls. The side wall of the other end of the protrusion 300 forms an arc-shaped arc portion 320, and the arc scale lines are distributed on the arc portion 320. The limiting groove 220 is located at the center of the arc portion 320. Therefore, when bending the arch wire 140, the relative rotation angle of the two orthodontic pliers can be measured according to the arc scale lines, that is, the orthodontic pliers can measure the torque angle when in use.

[0030] In order to facilitate reading the relative rotation angle of the two orthodontic pliers, indicator lines that match the arc scale lines are provided at both ends of the rotating shaft 170;

[0031] Among them, through the setting of the locking assembly, when the first clamp handle 100 and the second clamp handle 110 drive the first clamp beak 200 and the second clamp beak 210 to close, the locking assembly can keep the first clamp beak 200 and the second clamp beak 210 in a normally closed state, so that the operator does not need to hold and clamp the first clamp handle 100 and the second clamp handle 110 all the time, thereby facilitating the operator to bend the arch wire 140.

[0032] Combine Figure 2-Figure 5As shown, in this embodiment, the locking assembly includes a locking plate 120 arranged on the inner wall of the first clamp handle 100, a locking column 160 is provided on the side wall of one end of the locking plate 120, a mounting plate 130 is provided on the inner wall of the second clamp handle 110, and a locking hole 500 is provided on the side wall of the mounting plate 130. The mounting plate 130 slides toward the side of the locking column 160 to allow the locking column 160 to extend into the locking hole 500, thereby realizing the locking of the first clamp beak 200 and the second clamp beak 210 when closed.

[0033] When the first and second clamp handles 100 and 110 are clamped, the first and second clamp handles 100 and 110 are moved closer to each other, so that the first clamp handle 100 drives the locking plate 120 to drive the locking post 160 to move toward the position where the mounting plate 130 is located. When the first and second clamp beaks 200 and 210 are closed, the mounting plate 130 is pressed by the index finger to slide the mounting plate 130 toward the side of the locking post 160, so that the locking post 160 can extend into the locking hole 500, so that the locking hole 500 can limit and fix the locking post 160, thereby fixing the locking plate 120, so that the first and second clamp handles 100 and 110 cannot move away from each other, thereby keeping the first and second clamp beaks 200 and 210 in the normally closed state, which is convenient for the operator to bend the arch wire 140.

[0034] When the first beak 200 and the second beak 210 need to be released from the closed lock, the thumb presses the mounting plate 130, so that the mounting plate 130 drives the locking hole 500 to disengage the locking post 160, so that the first handle 100 and the second handle 110 can drive the first beak 200 and the second beak 210 to open;

[0035] The inner side wall of the second clamp handle 110 is provided with a mounting groove, and the upper side of the mounting plate 130 extends into the mounting groove. The side walls of the mounting groove are provided with through holes, which penetrate the second clamp handle 110. A sliding rod 230 is fixed in the through hole. The sliding rod 230 penetrates the mounting plate 130 along the moving direction of the mounting plate 130, thereby realizing the sliding installation of the mounting plate 130 in the mounting groove.

[0036] In actual use, in order to facilitate the operator to press the mounting plate 130 with the index finger or thumb, a fixing rod 150 is provided on the side wall of the mounting plate 130. The fixing rod 150 is set through the mounting plate 130, so that the fixing rod 150 can drive the mounting plate 130 to slide along the sliding rod 230, thereby facilitating the operator to drive the mounting plate 130 to open and close the first beak 200 and the second beak 210;

[0037] In actual use, a threaded hole 410 is provided on the side wall of the other end of the locking plate 120, and the locking plate 120 is fixed to the inner wall of the first clamp handle 100 by screws passing through the threaded hole 410, thereby better realizing the disassembly and assembly of the locking plate 120 on the inner wall of the first clamp handle 100;

[0038] In order to prevent the locking plate 120 from loosening during actual use when it is installed by screws, a fixing block 400 is fixed to the side wall of the other end of the locking plate 120. A groove that is compatible with the fixing block 400 is opened on the inner side wall of the first clamp handle 100. The fixing block 400 extends into the groove to limit the locking plate 120. The screw passes through the fixing block 400 to achieve the limited installation of the locking plate 120 on the first clamp handle 100.

[0039] Among them, through the setting of the groove and the fixing block 400, when the fixing block 400 extends into the groove, the fixing block 400 will not shake in the groove due to the adaptation of the groove and the screw will not shake in the groove, thereby better avoiding the screw from loosening during actual use.

[0040] Working principle: When the arch wire 140 needs to be bent, the operator drives the first clamp handle 100 and the second clamp handle 110 away from each other, so that the first clamp beak 200 and the second clamp beak 210 are opened, and the arch wire 140 is placed in the limiting groove 220, and the first clamp handle 100 and the second clamp handle 110 are gripped and clamped. At this time, the first clamp handle 100 drives the locking plate 120 to drive the locking column 160 to move toward the position of the mounting plate 130. When the first clamp beak 200 and the second clamp beak 210 are closed, by pressing the fixing rod 150 away from the locking plate 120, the fixing rod 150 can drive the mounting plate 130 to slide toward the locking column 160. The locking column 160 can be extended into the locking hole 500, so that the locking plate 120 is fixed, thereby keeping the first beak 200 and the second beak 210 in a normally closed state. Therefore, it is better to facilitate the two orthodontic pliers to clamp the fixed arch wire 140, and the arch wire 140 can be bent by rotating the orthodontic pliers relative to each other. When the bending is completed, by pressing the fixing rod 150 located on one side of the locking plate 120, the fixing rod 150 can drive the mounting plate 130 to drive the locking hole 500 to disengage from the locking column 160, so that the first pliers handle 100 and the second pliers handle 110 can drive the first pliers beak 200 and the second pliers beak 210 to open, thereby removing the arch wire 140.

[0041] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
