Description

Double sleeve with quick release structure

The present invention relates to a sleeve, and in particular to a double sleeve having a quick disassembly structure.

Generally, when the screw is unlocked, the screw is rotated by the pneumatic tool to complete the locking operation. When the size of the screw to be locked is different, the pneumatic tool must be equipped with a corresponding screw size sleeve to assist in the locking and unloading. In order to overcome the difficulty of different screw sizes, a sleeve structure is provided to assist people in locking and unloading.

Please refer to Figure 1. The sleeve structure is as follows, including:

a body 80 having a channel 81 and a through hole 82, the through hole 82 is through the outer wall of the body 80 to communicate with the channel 81;

a tool head 90, disposed in the channel 81 of the body 80, the tool head 90 has a card abutting portion 91;

a card plug 100 is inserted into the through hole 82 for abutting the card abutting portion 91;

a C-shaped buckle 110 is sleeved on the outer side of the body 80 at the perforation 82 for fixing the latch 100;

A spring 120 is disposed in the passage 81 of the body 80 for pushing against the tool head 90.

Thereby, the spring 120 pushes against the tool head 90, so that the locking portion 91 of the tool head 90 abuts against the latch 100, preventing the tool head 90 from coming off the channel 81.

However, the tool head 90 may cause damage after being used for a long time, and the tool head 90 must be replaced after the damage, and the plug 100 is also likely to rust under long-term use, resulting in the plug 100 being difficult to be detached from the body 80. The perforations 82 thus cause a lack of replacement of the tool head 90.

In view of this, the creators of the present invention have carefully studied and improved the above-mentioned deficiencies, resulting in the creation of a double-layer sleeve having a quick disassembly structure.

The purpose of the present invention is to solve the problem that the conventional sleeve is used for a long time, so that the rust of the plug causes the tool head to be easily separated from the sleeve.

In order to solve the above deficiency, the present invention is a double-layer sleeve with a quick disassembly structure, comprising:

a shaft tube having a perforation, a limiting wall and an axial passage extending through the shaft tube along an axial direction of the shaft tube, the perforation extending through the shaft tube and communicating with the axial passage The limiting wall is disposed on an outer wall surface of the shaft tube;

a tool head mounted in the axial passage, the tool head having a locking portion;

An inner elastic member is received in the axial passage, the inner elastic member is pushed against the tool head at one end, and the other end is pushed against the shaft tube;

a bead body movably mounted on the perforation, the bead body being used to abut or leave the locking portion of the tool head;

a sliding sleeve is slidably sleeved on the shaft tube, the sliding sleeve has a pressing portion and a dodging portion, the pressing portion is disposed from the sliding sleeve toward the axial passage, and the doping portion is disposed on the sliding portion Nested for the bead;

a positioning unit is disposed on the sliding sleeve for positioning the sliding sleeve;

Thereby, when in a combined state, the positioning unit positions the pressing portion at a position corresponding to the perforation, so that the bead body abuts against the locking portion of the tool head;

When in a disassembled state, the positioning unit positions the dodging portion at a position corresponding to the perforation, so that the bead body is separated from the locking portion of the tool head, and the tool head is detached from the axial passage.

With the above structure, the sliding sleeve is slid, and the bead body enters the dodging portion 403, and the tool head is not blocked by the bead body, and can be detached from the channel of the main body, thereby not only solving the difficulty of taking out due to rust. The problem with the tool head also makes it quicker and easier to replace the tool head.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this new model, please follow the brief description of the following:
