Description

One-way ratchet tool set

The invention relates to a tool set, and in particular to a tool set having a one-way ratchet joint.

According to the conventional hand tool, a sleeve is often used for a socket. For example, a screwdriver driver commonly used in the market has a handle, and a front end of the handle is axially connected with a shaft, and the free end of the shaft is sleeved with the sleeve. The sleeve system can be equipped with different screwdriver heads for different screw heads, so as to facilitate the user's operation. When the user wants to tighten or loosen a screw, the corresponding screwdriver head must be installed on the sleeve. The front end of the screwdriver head is engaged with the groove of the screw head, and the screwdriver can be rotated clockwise or counterclockwise, thereby allowing the user to tighten the screw or loosen the screw, which is common in the market. A T-wrench can also be used with this sleeve.

However, the screw driver and the T-wrench used in the above-mentioned matching sleeve have the following defects:

The screw driver and T-wrench used in the matching sleeve can be used to replace different screwdriver heads with different screw heads, and the purpose of tightening the screws and loosening the screws is achieved. However, when it is intended to be tightened or loosened, it is located in a narrow length. When the screw in the space is used, the shaft of the screwdriver or the insertion rod of the T-wrench must be inserted into the narrow space. The angle after the rotation is not convenient for the user to continue to rotate, and the user must turn the hand. The handle of the screwdriver and the handle of the T-wrench are released, and then re-held, in order to continue to rotate to achieve the purpose of tightening or loosening the screw, therefore, The hand tools that lead to the use, such as screwdrivers and T-wrenches, have the disadvantages of inconvenient operation and poor efficiency.

In view of the above, the inventors have observed that the above-mentioned shortcomings are considered to be necessary for further improvement of the conventional hand tools, and the present invention has been produced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a one-way ratchet tool set which improves the operational efficiency of a hand tool and further improves the convenience of the hand tool.

The ratchet teeth 331 rotate counterclockwise, so that the screwdriver bit sleeved on the second connecting portion 332 is reversely rotated to release the screw. When the counterclockwise rotation is performed to prevent the user from rotating the angle of the knob 121, the ratchet teeth 331 can be rotated. The handle 121 rotates clockwise. At this time, the oblique sides of the first reverse ratchets 322 will be slid away from the oblique sides of the second reverse ratchets 331 to make the driving member 32 idle without taking The ratchet member 33 is rotated, and the first reverse ratchet teeth 322 and the second reverse ratchet teeth 331 are kept in mesh with the spring 36, and the knob 121 is rotated clockwise to facilitate the user. When the position is operated, the user can rotate the handle 121 counterclockwise again to continue to loosen the screw, so that the user does not need to release the handle 121 and then re-hold during the loosening of the screw, thereby The user can connect the driving portion 11 of the operating member 10 to the forward joint unit 20 or the reverse joint unit 30, and through the first forward ratchet 222 and the second forward ratchet 231. The effect of the forward rotation is achieved, or the reverse rotation effect is achieved by the first reverse ratchet 322 and the second reverse ratchet 331, and the hands need not be removed during the forward rotation or the reverse rotation. The operating member 10 is continuously operated, thereby improving the efficiency of the operating hand tool and further improving the convenience of the hand tool.

Hereafter, the features of the present invention and its achievable efficacy are stated as follows:

The unidirectional ratchet tool set of the present invention can connect the driving portion 11 of the operating member 10 to the forward joint unit 20 or the reverse joint unit 30 according to user requirements, and pass through the first forward ratchet 222. And the second forward ratchet 231, the effect of the forward rotation is achieved, or the first reverse ratchet 322 and the second reverse ratchet 331 are achieved, and the reverse rotation effect is achieved, and the forward or reverse rotation is performed. During the process, the hands are not required to be removed, and the operation is continuously performed, thereby improving the efficiency of the hand tool and further improving the convenience of the hand tool.

In summary, the present invention has excellent advancement and practicability in similar products, and at the same time, the technical materials of such structures are frequently investigated at home and abroad, and the same structure is not found in the literature.
