Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a hand tool.

Description of the Prior Art

Generally, to screw a screwing member on an object, a user uses a tool which has a grip and a driving bit, the user grips on the grip and inserts the driving bit on the screwing member to rotate the screwing member. In addition, the driving bit gradually wears out after being used for a period of time, and the screwing members in different specifications needs to cooperate with driving bits which correspond to the screwing members in dimension; therefore, the user needs to carry many driving bits in various dimensions for different requirements. For convenience, on the market, there is a grip which is formed with a receiving portion, and the receiving portion is for a plurality of driving bits to be received therein, so the user does not need to carry a driving bit storage box, and s/he only needs to take down the driving bits from the receiving portion of the grip to replace the driving bits. This type of screwdriver handle is disclosed in TW408663.

However, although the conventional screwdriver handle can receive the driving bits, the driving bits are tightly arranged in the receiving portion to save space, and it's hard for the user to take up just one driving bit. On contrast, if the driving bits are spacingly arranged in the receiving portion, the receiving portion will occupy too much space, and a volume of the grip will largely increase.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The major object of the present invention is to provide a torque driving tool which can save a space of a receiving device and for a user to take up a driving bit conveniently.

To achieve the above and other objects, a torque driving tool is provided, including a main body, a working portion, a grip portion and at least one receiving device. The main body has an axial direction. The working portion is disposed on one of two ends of the main body for being assembled to a driving bit, and when the working portion receives a torque which is greater than a set torque value, the working portion slips relative to the main body. The grip portion is disposed on one of the two ends of the main body opposite to the working portion and optionally rotatable relative to the main body to adjust the set torque value, and the grip portion has at least one receiving groove. Each said receiving device includes a cover and a receiving portion which is for at least one said driving bit to be received therein, the cover is pivoted to the grip portion, and the receiving portion is swingably pivoted to the cover.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
