Palm wrench structure

The invention relates to a palm-type wrench structure, in particular to a palm-type wrench structure, which is provided with a body and a driving head group, wherein the driving head group is pivoted on the body, and the driving head group is rotatable relative to the body to each The angle makes the palm wrench structure of the present invention have multiple operations.

As is known in the prior art, the conventional palm-type wrench structure, such as U.S. Patent No. 6,976,408 B2, is based on a palm-type palm-type wrench structure, which mainly comprises: a circular body 10, the body The 10 series can be held by the user and rotated. The body 10 is provided with a receiving slot 11 . The receiving slot 11 is provided with a ratchet 20 . The ratchet 20 is provided with an active end 23 . The outer peripheral portion is provided with a blocking piece 40. The blocking piece 40 is pivoted between the body 10 and the body 10. The blocking piece 40 is for the user to manually move the body 10 to rotate. The body 10 is provided with a spiral. In the portion 12, the spiral portion 12 is configured such that the cover 50 is screwed to each other so that the ratchet 20 does not come out of the body 10.

However, the missing structure of the conventional structure is as follows: with the U.S. Patent No. 3, the body 10 and the working end 23 of the ratchet 20 are disposed on the same axial direction, that is, the conventional patented palm wrench structure is only single. A state of rotation, the expansion is insufficient.

In view of the lack of the structure of the above-mentioned conventional patented palm wrench, the inventor borrowed After years of experience in related industries, there has finally been a product that can solve the drawbacks of the palm-type wrench structure.

The body of the conventional hand-held wrench and the working end of the ratchet are disposed on the same axial direction, that is, the conventional palm-type wrench structure has only one single-rotating state, and the palm-type wrench of the present invention is provided with a body and a driving head. In the group, the driving head group can be rotated to various angles with respect to the body, so that the palm wrench structure of the present invention has multiple directional operational effects.

The utility model relates to a palm wrench structure, which comprises: a system having a first pivot portion, a first receiving groove, an inner circumferential surface and a first outer circumferential surface, and a notch; a driving head group can be accommodated on the inner circumferential surface of the body The driving head group is provided with a second pivot portion, the second pivot portion is pivoted with the first pivot portion, and the second pivot portion is internally provided with a third pivot portion and a first joint portion, the driving head Each of the two ends of the group is provided with a first working end and a second working end, the driving head set is provided with a first elastic-removing groove; the second connecting part is provided with a fourth pivoting portion, and the fourth pivoting portion is first The pivoting portion is pivotally disposed on the coupling member to be disposed in the first pivot portion, the second pivot portion and the third pivot portion, and the rod system is pivoted with the third pivot portion, the rod body The end portion is provided with a second joint portion to be screwed with the first joint portion, so that the drive head group is pivotally disposed on the first pivoting member by the two joint members; a pivot portion; the two coupling members and the first elastic member are symmetrical with respect to the driving head assembly.

The driving head group is rotated by the first pivot portion of the body and the coupling member. The driving head group can be operated in the same axial direction relative to the system, or can be arbitrarily adjusted relative to the body through the inner circumferential surface of the body. Angle or 90 degrees between the body and the axis In the operation mode, one of the driving ends of the driving head group is aligned with the positive notch, so that the palm wrench structure of the invention has multi-directional operation effect and has more practical use effect. The driving head group and the body have an axial 90-degree operation mode, and one of the driving ends of the driving head group is opposite to the positive notch, and the rotating body drives the driving head group and the rotating action end, the body and the driving When the head group is at ninety degrees, the first outer peripheral surface of the body and the outer peripheral surface of the driving head group are slightly combined in a circular cross shape to facilitate the rotation.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention.
