Abstract

An adjustable sleeve comprises an outer cylinder body, an inner cylinder body, a connecting body, a jaw component and two return springs. The inner cylinder body and the outer cylinder body can relatively slip in the axial direction. The jaw component is packed by the outer cylinder body and can be opened or closed under the action of the outer cylinder body. The adjustable sleeve has simple structure and can replace a set of sleeves with the different specifications for use, thereby reducing the number of accessories and facilitating the use.

Description

technical field [0001] The invention relates to a hand tool component for tightening nuts and other parts, in particular to an adjustable sleeve. Background technique [0002] The adjustable wrench of the prior art generally has a worm gear mechanism, which is used to control the movement of the movable pliers to achieve different openings, and the user needs to spend time to rotate the worm gear; An adjustable wrench, which uses a battery-driven motor to speed up the movement of the pliers to adjust the opening and closing of the jaws, saving time for adjusting the jaws; both of the above tools require some mechanical drive or transmission to achieve adjustment Features [0003] The ratchet wrench of the prior art has a ratchet function, but it requires a group of sleeves of different specifications for supporting use. Different sleeves should be installed for different objects during use, and sleeves of different specifications correspond to different working objects, an...
