Problems solved by technology

However, in the prior art, each structural component is vertically arranged, and the overall longitudinal length is large, which is not conducive to the requirement of miniaturized products and is not easy to carry. In addition, the tensioning spring is prone to elastic decline and affects normal use.

Abstract

The invention discloses a handheld device and aims at being used for installing or removing a screw by loading a screwdriver bit. The handheld device comprises a shell, in which a mounting space is formed, and a torsion control device; the torsion control device comprises a bearing seat, an output shaft and an annular adjusting portion; the bearing seat comprises an outer seat body with a housingspace and an inner seat body arranged in the housing space; the outer seat body and the inner seat body are mutually driven to rotate by a locking element; a plurality of limiting grooves are formed in the outer surface of the outer seat body; an elastic biasing element is arranged between the outer seat body and the annular adjusting portion; and a limiting element is arranged between the elasticbiasing element and the outer seat body. When the handheld device rotates, the shell drives the outer seat body to rotate through the limiting element; and the annular adjusting portion is provided with a limiting block for being abutted against the elastic biasing element and adjusts the position of the limiting block abutting against the elastic biasing element, so that abutting pressure of theelastic biasing element to the limiting element is adjusted, the preset maximum torsion of the screw at the screwdriver bit is adjusted, and the structure is more miniaturized.

Description

[0001] 【Technical field】 [0002] The present invention relates to a hand-held device, in particular to a hand-held device for loading a bit to install or remove screws. [0003] 【Background technique】 [0004] China Utility Model Patent No. 208451473 announced on February 1, 2019 discloses an easy-to-use anti-overload screwdriver, which is sequentially provided with a top nut for loading the screwdriver handle in the longitudinal direction, and one side of the top nut is movable. The socketed card slot, the clamping steel ball located in the card slot, the clamping plate for clamping the steel ball, and the fixing plate that clamps the clamping plate with the clamping spring, the user can adjust the position of the fixing plate to adjust the clamping The degree of compression of the spring can adjust the pressure of the top clamping plate on the top clamping steel ball, and then adjust the friction force between the top clamping steel ball and the groove and the surface of the...
