Dental force limiting wrench and assembling method thereof

Abstract

The invention relates to a dental force limiting wrench and an assembling method thereof. The dental force limiting wrench comprises a wrench body, an elastic part, a torsion block, a rotating shaft and a wrench head, wherein a rotating shaft assembling hole is formed in the front end of the wrench body; an installing hole communicating with the rotating shaft assembling hole is formed in the wrench body; the elastic part and the torsion block are arranged in the installing hole; one side of the rotating shaft is provided with a rotating shaft plane parallel to the axial direction of the rotating shaft; the front end of the torsion block is provided with a flat top end face; the edge of the wrench head is provided with a plurality of jaws; the bottom end of the rotating shaft penetrates through the rotating shaft assembling hole to be fixedly connected with the center of the wrench head during assembling, so that the rotating shaft can be rotationally arranged at the front end of the wrench body; and the elastic part abuts against the tail end of the torsion block, and the flat top end face of the front end of the torsion block enters the rotating shaft assembling hole to be attached to the rotating shaft plane, so that the torsion block can reciprocate in the axial direction of the installing hole when the rotating shaft rotates along with the wrench head.

Description

technical field [0001] The invention relates to the technical field of dental auxiliary equipment, in particular to a dental force limit wrench and an assembly method thereof. Background technique [0002] The form of the force limiting wrench in the traditional dental workshop is mostly the force limiting wrench in the form of a sleeve. Although it can achieve the function of complete force limitation, due to the different shapes of the workshops of dental equipment, the form of the sleeve is difficult for dismantling the workshop or installing work. It needs to be inserted from the head of the workshop during the process, so the operation is more inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dental force limiting wrench with simple structure and easy disassembly and an assembly method thereof. [0004] In order to solve the above technical problems, the dental force limiting wrench provided b...
