Abstract

The invention provides a movable sleeve. The movable sleeve comprises a barrel body and a plurality of clamping pieces. The barrel body is provided with an axial mounting hole used for mounting a driving rod and a plurality of eccentric arc grooves, wherein the eccentric arc grooves are located outside the axial mounting hole and uniformly distributed in the circumferential direction. The multipleclamping pieces are arranged in the barrel body and correspondingly and slidably arranged in the multiple eccentric arc grooves, the multiple clamping pieces are sequentially buckled head to tail, the inner side walls of the multiple clamping pieces are combined to a regular polygon locking hole, and under the action of the driving rod, each clamping piece slides along the corresponding eccentricarc grooves and moves relative to the adjacent clamping pieces to change the inner diameter of the locking hole.

Description

technical field [0001] The invention relates to the field of hardware tools, and in particular to a movable sleeve. Background technique [0002] The sleeve is a common tool for nut assembly. The diameter of the ordinary sleeve is fixed, so it is only suitable for the assembly of nuts of one specification. However, in actual production, a product usually includes nuts of various specifications; in this case, the operator needs to be equipped with multiple sleeves with different diameters; there are so many tools that it is very uncomfortable to use and carry. convenient. [0003] In order to solve this problem, some sleeves that can match nuts of different specifications have appeared on the market, such as a nut gun that is convenient for installing multiple nuts provided by Chinese patent CN207447828U. Hexagonal socket, so that multiple nuts of different types can be quickly installed. Although the integration of multiple inner hexagonal sockets with different diameters...
