Double sleeve with quick release structure

The present invention relates to a double-layer sleeve, and in particular to a double-layer 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 trouble of replacing the sleeve, 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 70, has a channel 71 and a perforation 72, the perforation 72 is through the outer wall of the body 70 to communicate with the channel 71;

a card plug 90 is inserted into the through hole 72 for abutting the card abutting portion 81;

a C-shaped retaining ring 100, sleeved at the outer side of the body 70 at the perforation 72 for fixing the latch 90;

A spring 110 is disposed in the passage 71 of the body 70 for pushing against the tool head 80.

The spring 110 is pushed against the tool head 80 such that the latching portion 81 of the tool head 80 abuts against the latch 90 to prevent the tool head 80 from coming out of the passage 71.

However, the tool head 80 may cause damage after being used for a long time, and the tool head 80 must be replaced after the damage, and the plug 90 is also likely to rust under long-term use, resulting in the card plug 90 being difficult to be detached from the body 70. The perforations 72 thus cause a lack of replacement of the tool head 80.

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.

a tool head capable of being mounted on the axial passage, the tool head having a locking portion at one end thereof, the engaging portion having an abutting surface and a clamping surface, the abutting surface being located at one end of the tool head The card surface is opposite to the abutment surface;

An elastic member is received in the axial passage, and the elastic member abuts against the abutting surface of the tool head;

a limit ring embedded in the positioning groove;

a bead body movably mounted to the perforation;

a sliding sleeve is slidably sleeved on the outer wall of the shaft tube, the sliding sleeve has a first limiting portion, a second limiting portion, a pressing portion and a dodging portion, the first limiting portion and The second limiting portion is recessed on the inner wall surface of the sliding sleeve, and the pressing portion protrudes from the sliding sleeve toward the axial passage, and the doping portion is formed by the sliding sleeve and the shaft tube For the shell

Thereby, the double sleeve with the quick disassembly structure can be actuated between a combined state and a disassembled state to position or disengage the bead;

When in the combined state, the limiting ring engages the first limiting portion of the sliding sleeve, and the pressing portion of the sliding sleeve is located at a position corresponding to the punching hole and is pressed against the bead body, so that the bead body abuts The card surface of the tool head;

When the detached state is in the disassembled state, the limiting ring is engaged with the second limiting portion of the sliding sleeve, and the dodging portion of the sliding sleeve is located at a position corresponding to the perforation, and the bead can be moved to the dodging portion to make the bead The body leaves the card face of the tool head.

With the above structure, the sliding sleeve is slid, and the bead body enters the dodging portion, 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 the rust due to the rust. The problem with the tool head also makes it quicker and easier to replace the tool head.
