Description

Tooth protecting bent angle capable of quickly replacing polishing cup Technical Field The utility model relates to the technical field of dental treatment apparatuses, in particular to a tooth protecting bent angle capable of quickly replacing a polishing cup. Background In oral medical services, the tooth care corner is widely applied to various oral treatment operations as a common dental treatment care device. At present, the conventional tooth protection bent angle in the market mostly adopts an integrated design, namely, a polishing cup is tightly combined with a bent angle main body and cannot be detached. This design exposes a number of problems during actual use. After each use, the polishing cup is difficult to separate, and the whole tooth protecting bent angle can be discarded as medical waste. Under a large number of oral treatment scenes, not only is considerable resource waste caused, but also the treatment capacity of medical waste is greatly increased. Further analysis, the corner body requires high cost from the processing of the parts to the final assembly during the manufacturing process due to the relatively complex transmission structure contained therein. Based on this, the operation of directly discarding the tooth care corner also increases the cost of oral treatment. Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present utility model. Disclosure of utility model The utility model aims to provide a tooth protecting bent angle capable of quickly replacing a polishing cup. In order to achieve the above purpose, the utility model adopts the following technical scheme: A tooth care corner for a quick change polishing cup comprising: A polishing cup and a bent angle main body; The first butt joint piece is arranged on the polishing cup; The second butt joint piece corresponds to the first butt joint piece and is arranged on the bent angle main body; The polishing cup is provided with a front end part and a rear end part which are integrally arranged, and the first butt joint piece is arranged on one side of the rear end part, which faces the bent angle main body; At least a portion of the rear end portion is movable relative to the front end portion; The tooth protection bent angle has an installation process and an installation state: In the installation process, the rear end part drives the first butt joint part, and the first butt joint part enters an installation position corresponding to the second butt joint part through movement in at least one direction; The first butt joint piece and the second butt joint piece form assembly positioning through resetting in the radial direction of the rear end part, so that the tooth protection bent angle enters an installation state. The first docking member and the second docking member form a docking structure, and in some embodiments described below, both form a quick-connect structure. In the scheme, through the butt joint and the separation of the first butt joint piece and the second butt joint piece, the polishing cup and the bent angle main body can be quickly assembled and disassembled, the polishing cup has higher convenience, the polishing cup can be replaced to keep the recycling of the bent angle main body, and the polishing cup has the effects of saving resources, reducing the oral cavity treatment cost and reducing the treatment amount of medical waste. The first butt joint piece is arranged on one side of the rear end part, which faces the bent angle main body, so that the blocking of the rear end part and the fitting of the bent angle main body can be avoided, and the occupation space of the tooth protection bent angle in the length direction of the bent angle main body is also prevented from being increased. In the installation process, the first butt joint part is driven by the rear end part, so that inconvenience in operation of the first butt joint part due to the position setting of the first butt joint part is avoided, the operation convenience is improved, and the situation that the first butt joint part and the second butt joint part cannot be separated due to the fact that the rear end part and the bent angle main body cannot be directly contacted after the rear end part and the bent angle main body are assembled in a fitting mode can be avoided. It should be emphasized that the working principle of the tooth protection corner is not changed, the corner main body can be provided with a shaft seat, and the second butt joint piece is arranged on the shaft seat. In some embodiments, the rear end portion is made of any one of medical silicone rubber (e.g., room temperature vulcanizing silicone rubber), thermoplastic elastomer, polyurethane. According to a further technical scheme, the first butt joint piece comprises two inserted bars, and the two inserted bars are arranged on one side of the rear end part, which faces the bent angle main body; The two i
