Problems solved by technology
Since the saw blade is made of thin steel sheet, there is a problem that it is easy to break during the application process. At the same time, the thin steel sheet structure can only be sawed in a straight line or a large arc when processing plaster models, and complex curves and fine sawing cannot be completed. , and these saw blades are relatively expensive due to the complicated production
Not only brings inconvenience to clinic, also causes great waste

Embodiment Construction
[0008] Refer to attached picture ， The plaster saw for orthodontics includes a saw bow 1, a handle 2, a bolt holder 3 and a saw blade 4. The saw blade 4 is composed of two steel wires twisted together, and saw teeth are formed by the convex-concave structure formed by the twisted steel wires. The front end of the saw blade is provided with a hanging ring 5, and the rear end is strip-shaped. The saw bow 1 is made of a metal material with a certain length and thickness that meets the requirements. The front end surface of the saw bow 1 is provided with a hanging groove 6, and the rear end is provided with a bolt hole 8 with a thread 7 along the direction of the saw blade. The bolt holder 3 is prepared in the bolt hole 8, and a fixing device is provided at the front end of the screw rod of the bolt holder 3. The hole 9 is used to lead the other end of the saw blade. After twisting the two strands of steel wire to form the saw blade, one end is fixed in the hanging groove 6 at the...

The invention relates to a plaster saw special for orthodontics. The plaster saw comprises a saw bow (1), a handle (2), a bolt fixer (3) and a saw blade (4), and is characterized in that: the saw blade (4) is formed by stranding two steel wires; convex and concave structures formed by stranding the steel wires form saw-teeth; a suspension loop (5) is arranged at the front end of the saw blade, and the rear end of the saw blade is strip-type; a hook (6) is arranged at the front end of the saw bow (1), and a bolt hole (8) with a thread (7) is formed along the direction of the saw blade in the rear end of the saw bow (1); the bolt fixer (3) penetrates through the bolt hole (8); and a fixing hole (9) is formed in the front end of a threaded rod of the bolt fixer (3), and is used for threading and guiding the other end of the saw blade. The plaster saw has a simple structure, and is low in cost and convenient to use; and barrier-free linear sawing or complex sweep-sawing can be freely realized.
Description
technical field [0001] The invention relates to a special gypsum saw for orthodontics, which is mainly used for processing gypsum models in orthodontics, and can cut straight lines or complex curves without hindrance on the gypsum models as required. Background technique [0002] In the clinical work of orthodontics, it is often necessary to use a plaster saw to cut the plaster model as needed. The structure of plaster saws currently used in orthodontics is similar to our common hacksaws. It consists of a saw bow and a saw blade. The giant bow is shorter, and the saw blade is a narrow sheet-like structure. One side of the saw blade is sawtooth. , and the other side is straight. Since the saw blade is made of thin steel sheet, there is a problem that it is easy to break during the application process. At the same time, the thin steel sheet structure can only be sawed in a straight line or a large arc when processing plaster models, and complex curves and fine sawing cannot ...
