AI Technical Summary
Technical Problem
The threaded connections of existing dental handpieces are difficult to clean and cumbersome to disassemble and assemble, increasing the time cost and operational difficulty of cleaning and maintenance.
Method used
The screw and transmission assembly are designed to be parallel to each other. The axial positioning of the head assembly is achieved through the limiting groove and the tapered groove. The screw can be locked or unlocked simply by turning it, preventing impurities from entering the threaded connection.
Benefits of technology
It reduces the difficulty of cleaning dental handpieces, simplifies the operation of changing the handpiece head and maintaining the equipment, and improves work efficiency.

Abstract
The utility model relates to the technical field of medical instruments, in particular to a dental bent handpiece which comprises a handpiece assembly, a transmission assembly, a lining assembly, a screw rod and an elbow handle, the transmission assembly and the lining assembly are arranged in the elbow handle at a preset bending angle; the bottom end of the lining assembly abuts against the elbow handle, and the top end of the lining assembly abuts against the transmission assembly. One end of the machine head assembly is in meshed transmission with the transmission assembly, and the other end extends out of the top end of the machine head assembly; a limiting groove is formed in the outer wall of the machine head assembly; one end of the screw abuts against the limiting groove, and the other end of the screw is arranged in the bottom end of the elbow handle. The screw is in threaded connection with the transmission assembly, and the axes of the screw and the transmission assembly are parallel. The included angle between the screw rod and the machine head assembly is the preset bending angle, then the top end of the screw rod can stretch into the limiting groove, the screw rod abuts against the inner wall of the limiting groove and / or the groove bottom corner of the limiting groove, axial limiting of the machine head assembly is achieved, and the situation that the machine head assembly is disengaged from the elbow handle in the treatment process is avoided.
