Technical Field

[0001] The utility model belongs to the technical field of dental tools, and in particular relates to a composite spiral reamer. Background Art

[0002] In dentistry, it is often necessary to replace a portion of a tooth after partially removing it. In this process, a composite spiral reamer is usually used to remove or replace the tooth, which is usually composed of a handle and a threaded cutting edge.

[0003] At present, when a composite spiral reamer falls, its spiral portion will hit the ground first and be subjected to a large impact force. Since the spiral portion of the composite spiral reamer used in dentistry is usually slender and lacks protective measures, the spiral portion is easily bent after being subjected to the impact force. During this process, the spiral portion is also easily worn, thereby affecting the normal use of the composite spiral reamer and being not conducive to protecting the spiral portion of the composite spiral reamer during placement. Utility Model Content

[0010] Preferably, a threaded annular plate is connected to the top of the annular plate, and the threaded annular plate is threadedly connected to the inner wall of the protective shell.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model sets a protective component structure, rotates the screw rod so that one end of the screw rod disengages from one of the thread grooves, so that the protective shell is released from the limit on the gripping part, and then pulls the protective shell downward so that the protective shell moves downward on the protrusion through the concave plate, so that the protective shell completely covers the spiral part, and then rotates the screw rod so that the screw rod is threadedly connected with another thread groove, thereby limiting the protective shell, realizing protection of the spiral part after use, which is beneficial to protecting the spiral part when it falls, and the normal use of the composite spiral auger, thereby improving the practicality of the composite spiral auger.

[0013] (2) The utility model provides a cleaning component structure. When it is necessary to clean the outer wall surface of the spiral part, the hollow rubber tube drives the cleaning pad to fully contact with the spiral part through the elastic force of the hollow rubber tube through the docking plate. When the protective shell moves, it drives the annular plate to move, so that the cleaning pad and the surface of the spiral part rub against each other, thereby realizing rapid cleaning of the surface of the spiral part, improving the cleaning efficiency of the surface of the spiral part, facilitating the use of operators, and improving the convenience of the composite spiral auger.
