Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

Referring to fig. 1 to 5, the novel folding wrench according to an embodiment of the present invention includes a wrench head 1, a first connecting member 2, a second connecting member 3, and a handle 4, wherein the wrench head 1, the first connecting member 2, and the second connecting member 3 are all flat, two end portions of the first connecting member 2 are respectively rotatably connected to the wrench head 1 and the second connecting member 3, the handle 4 is cylindrical, and the handle 4 is fixedly connected to the second connecting member 3.

Preferably, the wrench head 1 includes a working portion 11 and a connecting portion 12, the working portion 11 is fixedly connected to the connecting portion 12, and a first through hole 121 is formed in the connecting portion 12.

Preferably, both ends of the first connecting member 2 are concave, the depressions at both ends of the first connecting member 2 are respectively provided with a first connecting rod 5 and a second connecting rod 6, and the first connecting rod 5 and the second connecting rod 6 are fixedly connected with the first connecting member 2.

Preferably, the first connecting rod 5 penetrates the first through hole 121 to be sleeved and connected with the connecting part 12. I.e. the first attachment member 2 is rotatable in a direction perpendicular to the plane in which the wrench head 1 is located.

Preferably, a second through hole 31 is formed in the left end of the second connecting member 3, and the second connecting rod 6 penetrates through the second through hole 31 to be connected with the second connecting member 3 in a sleeved mode. I.e. the second connecting element 3 can rotate in a direction perpendicular to the plane of the first connecting rod 5;

furthermore, if only the first connecting rod 5 is provided, a user can hold the first connecting rod 5 to rotate when rotating the wrench, so that the phenomenon of low efficiency is caused easily without exerting force, and therefore the second connecting piece 3 is arranged, and the user can take down parts by holding the handle 4 on the second connecting piece 3.

Preferably, the diameter of the first connecting rod 5 is smaller than the inner diameter of the first through hole 121, and the length of the first connecting rod 5 is greater than the length of the first through hole 121. I.e. it is ensured that the first connecting rod 5 is rotatable through the first through hole 121.

Preferably, the diameter of the second connecting rod 6 is smaller than the inner diameter of the second through hole 31, and the length of the second connecting rod 6 is greater than the length of the second through hole 31. I.e. to ensure that the second connecting rod 6 is rotatable through and within the second through hole 31.

Preferably, reinforcing ribs 7 are arranged at the joints of the first connecting piece 2, the first connecting rod 5 and the second connecting rod 6. When the folding wrench is used, the stress borne at the connecting position of the first connecting piece 2, the first connecting rod 5 and the second connecting rod 6 is larger, so that the structure of the reinforcing rib 7 is increased, the stability of the folding wrench is improved, and the service life of the folding wrench is prolonged.

From the above, for the part in the narrow space, after the first connecting piece 2 is rotated to a proper angle, the working part 11 in the wrench head 1 is aligned with the part and sleeved on the part, and then the second connecting piece 3 is rotated to a proper angle, the user grips the handle 4, and the folding handle is rotated counterclockwise integrally, so that the part can be taken down. The folding wrench can complete work in a narrow environment; the second connecting piece and the handle are matched with each other, so that a larger moment can be obtained during rotation, and parts can be taken down more easily; the arrangement of the reinforcing ribs improves the service life of the folding wrench.
