Palm wrench structure

The present invention relates to a palm-type wrench structure. The body of the palm-type wrench structure of the present invention, the first driving member and the second driving member can have a large adjustment angle, and the system is provided with a notch. The flat-shaped operating state, the palm-type wrench structure of the present invention has a large adjustment angle and has a flat operating state, and has the best balance structure.

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 10 The body 10 is provided with a slot 11 in the body 10. The slot 11 is provided with a ratchet 20, and the ratchet 20 is provided with an active end 23; the periphery of the body 10 A blocking piece 40 is disposed between the blocking piece 40 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 portion. 12. The spiral portion 12 is configured such that the cover bodies 50 are screwed to each other such that the ratchet wheel 20 does not come out of the body 10.

However, the missing structure of the conventional hand-held wrench is: please supplement 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 rotation state, expansion is insufficient.

The patent application filed by us, Taiwan application number: 103119629, certificate number: I513549, patent name: rotary wrench structure, the structure of the patent system is provided with a body 10 and a driving head 30, the body 10 is provided with a notch 24, The driving head 30 is pivotally disposed with respect to the body 10. When the operation is performed, the axis of the driving head 30 can be adjusted to intersect with the axis of the body 10 at a point. The finger and the index finger can be supported on the outer peripheral surface of the driving member 30, and the palm rests on the outer peripheral surface 14 of the body 10. The body 10 can be used as a moment, and is more convenient for the grip of the hand and the palm wrench structure. The body 10 is provided with a notch 24 and has an advantage of being adjusted to be flat.

Another Taiwan patent application number: 102130941, certificate number: I522209, US patent application number: 13/604691, publication number: 2014/0060258, patent name: ratchet wrench tool, please supplement the figure 1 of the bulletin, with a grip The portion 12, the balance ring 24 and the ratchet member 28 are pivotally disposed with the grip portion. The ratchet member 28 is pivotally disposed with the balance ring 24, thereby forming a three-layer structure.

In the patent structure of Taiwan Application No. 102130941, the three can be adjusted to be in the state of rotation as shown in Figure 1. Compared with the patent application of Taiwan Application No. 103119629, the two-layer structure has a larger adjustment angle expansion, but the Taiwan application The patent structure of No. 102130941 cannot be adjusted to the operation state of the third figure of Taiwan Application No. 103119629, and the operation state of the third figure of Taiwan Application No. 103119629 is the rotation state of the maximum probability of the palm wrench, the general palm wrench The operational status of Figure 1 that needs to be adjusted to Taiwan Application No. 102130941 is quite low. The two applications have their own advantages and disadvantages, and the advantages and disadvantages between the two are in conflict, so there is a lack of both. .

In view of the above-mentioned lack of the structure of the conventional hand-held wrench, the inventor has been engaged in the manufacturing, design and production experience of related industries for many years, and finally has a product of a palm wrench structure that can solve the drawbacks of the conventional use.

The two applications in the conventional palm-type wrench structure have their own advantages and disadvantages, and the advantages and disadvantages between the two have conflicts. Therefore, there is a lack of both. The present invention relates to a palm wrench structure. The body of the palm-type wrench structure of the present invention, the first driving member and the second driving member can have a large adjustment angle, and the system is provided with a notch, so that the flat state of operation, the case The palm wrench structure has a large adjustment angle and has a flat operating state, and has the best balance structure.

A palm-type wrench structure includes: a body; a first driving member is arbitrarily adjustable in angle with respect to the body; the second coupling member is configured to pivot the first driving member on the body; and a second driving member is at one end The second driving member is disposed on the first driving member, and the second driving member is opposite to the first driving member. An umbrella-shaped movement adjustment angle; a pivoting rod pivots the first driving member and the second driving member, and the second driving member is umbrella-shaped with respect to the first driving member with the pivoting rod as an axis angle.

The first driving member is pivoted about the first pivot portion and the coupling member, so that the first driving member can be arbitrarily adjusted with respect to the body through the inner circumferential surface, and the second driving member is The first pivoting portion of the first driving member and the pivoting rod are axial centers, so that the universal seat is actuated in the receiving portion to adjust the second driving member relative to the first The angle of the driving member rotates the first driving member and the second driving member to adjust the angle, so that the palm wrench structure of the invention achieves multi-directional operation efficiency. The second driving member is disposed outside the first driving member, and the thumb and the index finger of the human hand can be supported on the outside of the second driving member, and the palm rests against the body and the first The end face of the driving member is more convenient for the grip between the hand and the palm wrench.
