Description

Tool tooth engagement structure

The present invention relates to a tool tooth engaging structure, in particular to a double-sided beveled edge designing through a tooth portion of a tool component, and in addition to being operable in a normal state, the working object of the broken corner can also be operated. When the tool component is reversed, each tooth portion can be in a good torsion state, so as to achieve the multi-purpose effect of the tooth portion.

For the conventional tool tooth portion, as shown in Figures 1, 2 and 3, the tool member (10) is preset with a receiving hole (11), and the receiving hole (11) is formed with a tooth portion (12). Therefore, after the corresponding work object (13) is placed in the receiving hole (11), the tool member (10) can reach the rotation control through the card of the tooth portion (12) and the work object (13); but sometimes In the state of the original size of the angled work (14), the original size tool tooth (12) will not be able to get stuck and idle.

Therefore, the manufacturer has developed a tooth structure for the cornering operation, as shown in Figures 4, 5, 6, and 7, the tool member (20) has a plurality of teeth (21) at the edge of the hole (25). The center of the tooth portion (21) forms a right sharp corner (22) or a left sharp corner (23) structure, and the left and right sharp corners (23) (22) are adjacently set, and the left and right sharp corners (23) (22) the rear end extends with a flat end (24), and the front end is formed with a concave portion (26); through the above structure, when the tool component (20) is directed to the work (27) or the cornering work (28) When operating, whether there are forward or reverse, there will be three right sharp corners (22) or The left side corner (23) and the side flat end (24) are snapped, which will provide a wider range of performance.

However, since the tool member (20) and the workpiece (27) or the cornering work (28) have only three points of application, the torque of the operation will be reduced, and the halving of the force point will force The force of operation needs to be increased, which may cause damage to the contact point of the work (27).

Furthermore, as shown in Fig. 5, when the tool member (20) is operated using a ratchet rotation, it will generate an idle distance of 10 degrees or more, so that if there is a need for a small space rotation, it may cause difficulty in use or inoperability. The state of the person.

In view of the fact that the tool tooth portion still has room for improvement in the operation of the cornering work, the inventor further develops the tooth engagement structure of the tool of the present invention, that is, the main purpose is to slant through the bilateral direction of the tooth portion of the tool member. The corner design makes it possible to operate the work with the corners in addition to the work in the normal state.

Secondly, regardless of the forward or reverse rotation of the tool parts, the beveling operation can be performed by the beveled edge of one side of each tooth, so that each of the rotating operation tool parts has six planes and the work objects are mutually offset. According to to achieve a good torque output state.

Thirdly, by the toothed portion and the surface of the workpiece and the surface of the workpiece, it is possible to protect the workpiece from damage caused by the operation.

Fourth, the idling angle of the sway is only 4 degrees, which will be beneficial to the operator of the small space.
