By moving the transmission head upward or pushing the sliding rod downward, the receiving groove corresponds to the restriction member positionally so that the socket sleeved onto the transmission head can be unlocked to remove.

Description

Quick release drive tool

The present invention relates to a driving tool, in particular, to a driving tool that can quickly remove and attach a sleeve.

Press, generally the ratchet tool for connecting the sleeve is provided with a movable positioning mechanism on the exposed part of the ratchet head, so as to selectively insert into the positioning hole or positioning groove of the inner wall of the sleeve, so that the sleeve cannot be disengaged and ensure the driving operation. stability and security.

For example, as shown in patent TW M538442, a sliding member passes through the ratchet head and tends to move upward due to the elastic force of the elastic member. When the release button is pushed to move the sliding member down, the position of the groove corresponds to the ball, the ball can partially enter the groove without being exposed outside the ratchet head, and the sleeve can be released or inserted. On the contrary, when the groove The position does not correspond to the ball, the ball protrudes beyond the ratchet head, and the sleeve cannot be disengaged or inserted.

Currently on the market, as described in the above-mentioned patents, the sliding rod and the element that can control the sliding of the sliding rod are used to achieve the unlocking and locking functions. However, when the user needs to insert the sleeve, he must hold the tool at the same time. , It is very inconvenient to hold down the release button, and it is even difficult to operate with one hand. If you want to operate with one hand, the release button must be designed to be easier to press, which may lead to accidental touches.

One of the objects of the present invention is to provide a drive tool that can be quickly and easily unlocked to remove the sleeve.

In order to achieve the above object, the present invention provides a quick-release driving tool, which includes a main body, a ratchet head, at least one locking block, at least one steering mechanism, a sliding rod, an elastic member and a limiting member.
