Description

Technical Field

[0001] The present application relates to the technical field of dental instruments, and in particular to a pair of tweezers for processing dental dentures. Background Art

[0002] When processing dentures, porcelain needs to be applied to the denture surface, and tweezers need to be used to clamp the denture to avoid interference with the coating work.

[0003] Conventional tweezers are always open and require the operator to hold them tightly to clamp objects. The operator needs to hold them tightly at all times, which requires the operator to apply continuous force and is prone to mistakes.

[0004] To this end, the present application provides a pair of tweezers for dental denture processing. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a pair of tweezers for dental denture processing, which overcomes the shortcomings of the existing technology and aims to solve the problem that conventional tweezers are always open and require the operator to hold them tightly to clamp objects, and the operator needs to pinch them tightly at all times, requiring the operator to exert continuous force, which is prone to mistakes.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a pair of tweezers for dental denture processing, comprising a first tweezers rod, a second tweezers rod installed on one side of the first tweezers rod, an automatic clamping mechanism provided on the top of the first tweezers rod and the second tweezers rod, the automatic clamping mechanism comprising an oblique rod, the oblique rod being fixedly installed on the top of the first tweezers rod, an adjusting piece being fixedly installed on the top of the second tweezers rod, an adjusting hole matching the oblique rod being provided inside the adjusting piece, one end of the oblique rod being passed through the adjusting hole and fixedly connected to a first clamping rod, the end of the adjusting piece away from the second tweezers rod being fixedly installed with a second clamping rod, the second clamping rod and the top of the first clamping rod being fixedly connected to a clamping portion.

[0007] By adopting the above technical solution, when the denture to be processed has multiple crowns, the top of the first tweezers rod and the second tweezers rod are pressed at the same time to move the oblique rod in the adjusting member, so that the oblique rod and the adjusting member move in opposite directions at the same time, thereby driving the first clamping rod and the second clamping rod away from each other, so that the second clamping rod and the first clamping rod can be respectively extended into the two crowns. After loosening, since the crowns separate the first clamping rod and the second clamping rod, the oblique rod cannot move in the direction away from the adjusting member, so that the tweezers automatically clamp the inner side of the crown, and the operator does not need to continue to exert force, which is convenient for subsequent processing or operation. When loosening, it is only necessary to press the top of the first tweezers rod and the second tweezers rod at the same time again to increase the distance between the first clamping rod and the second clamping rod, and the tweezers can be taken out. After taking out, the first tweezers rod and the second tweezers rod are released, and the oblique rod moves in the adjusting member, so that the first clamping rod and the second clamping rod automatically fit together and recover, which helps to reduce the burden on the operator and greatly improves work efficiency.

[0008] As a preferred technical solution of the present application, a soft pad is provided on the side of the first tweezers rod away from the second tweezers rod, and the material of the soft pad is rubber.

[0009] By adopting the above technical solution, the cushion is made of rubber, which can absorb the pressure when the hand is holding it, thereby improving the comfort of holding it.

[0010] As a preferred technical solution of the present application, the top of the clamping portion is rounded.

[0011] By adopting the above technical solution, the top of the clamping part is rounded to reduce the pressure concentration point on the denture surface, achieving gentle clamping, which is beneficial to protecting the denture surface from accidental scratches.

[0012] As a preferred technical solution of the present application, a plurality of groups of anti-slip strips are fixedly installed on the side wall of the soft cushion, and the plurality of groups of anti-slip strips are evenly distributed along the side wall of the soft cushion.

[0013] By adopting the above technical solution, the friction between the hand and the soft pad is increased by the anti-slip strip, which prevents the tweezers from slipping during use, and is conducive to the stable grip of the tweezers during the denture processing operation.

[0014] As a preferred technical solution of the present application, two groups of T-shaped soft card blocks are fixedly installed on the side of the soft pad away from the anti-slip strip, and two groups of card slots are opened inside the first tweezers rod and the second tweezers rod, and the two groups of T-shaped soft card blocks are clamped inside the card slots.

[0015] By adopting the above technical solution, the T-shaped soft card block is clamped in the card slot to achieve a detachable connection between the soft pad and the first tweezers rod or the second tweezers rod, which facilitates cleaning of the soft pad.

[0016] As a preferred technical solution of the present application, the second clamping rod is fitted with the first clamping rod.

[0017] By adopting the above technical solution, the second clamping rod and the first clamping rod are fitted together without being subjected to external force, so that the two sets of clamping parts of the first clamping rod and the second clamping rod are in a precisely aligned position when preparing to clamp the denture, thereby improving the accuracy and consistency of clamping.

[0018] As a preferred technical solution of the present application, the first tweezers rod and the second tweezers rod are made of titanium alloy.

[0019] By adopting the above technical solution, the titanium alloy material has the advantages of high strength, corrosion resistance, and no allergies, ensuring the durability and precision of the tweezers.

[0020] Beneficial effects of this application:

[0021] After removal, release the first tweezers rod and the second tweezers rod, and the oblique rod moves in the adjusting member, so that the first clamping rod and the second clamping rod are automatically fitted and restored, thereby reducing the burden on the operator and greatly improving work efficiency.

[0022] 2. The cushion material is rubber, which can absorb the pressure when holding the hand and improve the comfort of holding. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] When the denture to be processed has multiple crowns, the tops of the first tweezers rod 1 and the second tweezers rod 2 are pressed at the same time to move the oblique rod 301 in the adjusting member 302, so that the oblique rod 301 and the adjusting member 302 move in opposite directions at the same time, thereby driving the first clamping rod 4 and the second clamping rod 5 away from each other, so that the second clamping rod 5 and the first clamping rod 4 can be respectively extended into the two crowns. After loosening, since the crowns separate the first clamping rod 4 and the second clamping rod 5, the oblique rod 301 cannot move in the direction away from the adjusting member 302, so that the tweezers automatically clamp the inner side of the crown, without the operator having to exert force continuously, which is convenient for later use. For continued processing or operation, when releasing, it is only necessary to press the top of the first tweezers rod 1 and the second tweezers rod 2 at the same time again to increase the distance between the first clamping rod 4 and the second clamping rod 5, and the tweezers can be taken out. After taking them out, release the first tweezers rod 1 and the second tweezers rod 2, and the inclined rod 301 moves in the adjustment part 302 to make the first clamping rod 4 and the second clamping rod 5 automatically fit together and restore, which helps to reduce the burden on the operator and greatly improves work efficiency; by setting the top of the clamping part 6 as a rounded corner, the pressure concentration point on the denture surface is reduced, and gentle clamping is achieved, which helps to protect the denture surface from accidental scratches.

[0031] Reference Figure 4 A soft pad 7 is provided on the side away from the first tweezers rod 1 and the second tweezers rod 2, and the material of the soft pad 7 is rubber; a plurality of groups of anti-slip strips 8 are fixedly installed on the side wall of the soft pad 7, and the plurality of groups of anti-slip strips 8 are evenly distributed along the side wall of the soft pad 7;

[0032] Because the soft pad 7 is made of rubber, it can absorb the pressure when the hand is holding it, thereby improving the comfort of holding it; the anti-slip strip 8 increases the friction between the hand and the soft pad 7, preventing the tweezers from slipping during use, which is conducive to the stable holding of the tweezers during the denture processing operation.

[0033] Reference Figure 2-4 Two groups of T-shaped soft clamping blocks 9 are fixedly installed on the side of the soft pad 7 away from the anti-slip strip 8. Two groups of card slots 10 are opened inside the first tweezers rod 1 and the second tweezers rod 2, and the two groups of T-shaped soft clamping blocks 9 are clamped into the inside of the card slot 10; the first tweezers rod 1 and the second tweezers rod 2 are made of titanium alloy; by clamping the T-shaped soft clamping block 9 into the inside of the card slot 10, the soft pad 7 is detachably connected to the first tweezers rod 1 or the second tweezers rod 2, which is convenient for cleaning the soft pad 7; the titanium alloy material has the advantages of high strength, corrosion resistance, and no allergies, ensuring the durability and precision of the tweezers.

[0034] Reference Figure 1 , the second clamping rod 5 is fitted with the first clamping rod 4; the second clamping rod 5 is fitted with the first clamping rod 4 without receiving external force, so that the two sets of clamping parts 6 of the first clamping rod 4 and the second clamping rod 5 are in a precisely aligned position when preparing to clamp the denture, thereby improving the accuracy and consistency of clamping.

[0035] Working principle: When the denture to be processed has multiple crowns, press the top of the first tweezers rod 1 and the second tweezers rod 2 at the same time to move the inclined rod 301 in the adjusting member 302, so that the inclined rod 301 and the adjusting member 302 move in opposite directions at the same time, thereby driving the first clamping rod 4 and the second clamping rod 5 away from each other, so that the second clamping rod 5 and the first clamping rod 4 can be respectively extended into the two crowns. After loosening, the crowns separate the first clamping rod 4 and the second clamping rod 5, so that the inclined rod 301 cannot move away from the adjusting member 30 2, so that the tweezers automatically clamp the inner side of the crown. When releasing, it is only necessary to press the top of the first tweezers rod 1 and the second tweezers rod 2 at the same time again to increase the distance between the first clamping rod 4 and the second clamping rod 5, and then the tweezers can be taken out. After taking out, the first tweezers rod 1 and the second tweezers rod 2 are released, and the oblique rod 301 moves in the adjusting member 302, so that the first clamping rod 4 and the second clamping rod 5 are automatically fitted and restored. The soft pad 7 is made of rubber, which can absorb the pressure when the hand is holding, thereby improving the comfort of holding;

[0036] The top of the clamping portion 6 is rounded to reduce the pressure concentration point on the denture surface, and the anti-slip strip 8 increases the friction between the hand and the soft pad 7;

[0037] At the same time, the T-shaped soft clamping block 9 is clamped into the inside of the clamping slot 10 to achieve a detachable connection between the soft pad 7 and the first tweezers rod 1 or the second tweezers rod 2; the second clamping rod 5 is fitted with the first clamping rod 4 in the absence of external force, so that the first clamping rod 4 and the second clamping rod 5 are in a precisely aligned position when the two clamping parts 6 are ready to clamp the denture;
