The invention provides a tooth-implanting spanner realizing adjustment on torsion. The tooth-implanting spanner comprises a handheld unit, a drive unit, a fixing unit and a stopping unit, wherein the handheld unit is provided with a flexible holding part with flexibility, an open measuring space, a working part located at one end of the flexible holding part, and a handheld part located at the other side of the flexible holding part; the driving unit is arranged on the working part; the fixing unit is provided with a fixing part arranged in the open measuring space, a measuring part extending from the fixing part, and a plurality of positioning parts which are arranged on the measuring part and are distributed in sequence from the fixing part towards the direction of an abutting surface; the stopping unit can be located to any of the positioning parts, therefore, the stopping unit can be selectively located to one of the positioning parts, so that when the flexible holding part of the handheld unit is pulled to enable the abutting surface to abut against the stopping part, a driving part is enabled to achieve a preset torsion value.
Description
technical field [0001] The invention relates to a dental implant wrench, in particular to a dental implant wrench with adjustable torque. Background technique [0002] see figure 1 , is an implant wrench 50 in the prior art, which has a fixed part 51, a working part 52 from one end of the fixed part 51 and a pulling part 53 connected to the working part 52, and the fixed part 51 has a measuring part 54 Extends from this fixing portion 51 . When in use, the dentist combines the working part 52 with an artificial tooth root (not shown), and then holds the trigger part 53 to turn it, so that the operator can then compare the measurement when turning the trigger part 53 The indicated torque value of the measuring piece 54 is used to obtain the current output torque. When the wrenching part 53 is aligned with the predetermined torque indicating value of the measuring piece 54, it means that the operator has turned it to reach the predetermined torque value, that is, the rotatio...
