Dental low-speed handpiece disassembling device

Abstract

The invention discloses a dental low-speed handpiece disassembling device. The disassembling device comprises a first sleeve, a first through hole and a second through hole which communicate with eachother are formed in the first sleeve, the diameter of the first through hole is smaller than that of the second through hole, a second sleeve is arranged in the first through hole in a matched mode,a limiting convex edge matched with the second through hole in diameter is arranged at the bottom of the second sleeve, a downward pressing convex edge is arranged on the inner periphery of the top ofthe second sleeve, a third sleeve is arranged at the bottom of the first sleeve in a thread fit mode, and an upper jacking convex edge is arranged on the inner periphery of the bottom of the third sleeve. The disassembling device is specially used for disassembling a NSK dental low-speed handpiece of the structure recorded in the background technology, the disassembling and maintaining time is shortened on the premise that parts are not damaged, and the maintaining quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of dental maintenance equipment, in particular to a dental low-speed mobile phone disassembler. Background technique [0002] Dental handpiece is a commonly used medical device in stomatology. It realizes the treatment of teeth or oral tissue by clamping various types of burs. The existing NSK dental low-speed handpiece uses a clamping sleeve and a mandrel to clamp the bur The holding structure, the disc spring that exerts thrust on the clamping sleeve is fixed and installed in the limit groove of the rotating shaft through the clamping spring. The installation of the air motor is fixed by a pressure ring with threads on the outer circumference. The overall structure is small and precise. If it is disassembled Different special tools are used for each different part. The actual operation is very troublesome, and even a slightly violent disassembly method is used, which is easy to cause damage to the parts an...

[0002] Dental handpiece is a commonly used medical device in stomatology. It realizes the treatment of teeth or oral tissue by clamping various types of burs. The existing NSK dental low-speed handpiece uses a clamping sleeve and a mandrel to clamp the bur The holding structure, the disc spring that exerts thrust on the clamping sleeve is fixed and installed in the limit groove of the rotating shaft through the clamping spring. The installation of the air motor is fixed by a pressure ring with threads on the outer circumference. The overall structure is small and precise. If it is disassembled Different special tools are used for each different part. The actual operation is very troublesome, and even a slightly violent disassembly method is used, which is easy to cause damage to the parts and affect the use of the dental handpiece. Currently, there is no special tool for this type of structure in the market. Repair tools, resulting in too long disassembly time, repair quality is not guaranteed
