Description

Technical Field

[0001] The invention relates to a multi-section bending joint which is installed on the head of a hand tool so as to facilitate a user to apply force to a target object (such as a screw). Background Art

[0002] Hand tools are essential tools for repairing and installing equipment. For example, the more common wrenches are generally used to loosen and tighten screws and nuts. However, common open-end wrenches require a larger operating space to be used smoothly and continuously. If used in a small space, it will be restricted by the environment. The wrench must be removed after swinging a slight angle, and then re-screwed and turned, which is quite time-consuming. Therefore, technicians in the relevant field have further developed the use of ratchet wrenches and socket joints, so that users do not need to remove the wrench from the screw to keep turning, and only need to replace the socket joint of the corresponding size to deal with screws of different specifications. It is faster and more convenient to use than ordinary open-end wrenches.

[0003] However, in conventional ratchet wrenches, the angle between the socket joint and the wrench body is fixed. Therefore, a spherical head is provided between the connection between the socket joint and the wrench body so that the socket joint can be bent relative to the wrench body. Although this structure can reach more positions compared to conventional wrenches without a bending structure, the current design still has a limited angle at which the socket joint can be bent relative to the wrench body, and there is still room for improvement.

[0004] In view of the above-mentioned problems, how to further improve the bending angle of the sleeve relative to the wrist body is a problem that needs to be actively overcome in the current industry. Summary of the invention

[0005] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a multi-section bending joint, which improves the existing problems by utilizing a structure in which the two ends of the joint part respectively have a first spherical head and a second spherical head. Since the two ends of the joint part respectively have a first spherical head and a second spherical head, the first spherical head and the second spherical head can be respectively assembled in the first joint groove of the first connecting part and the second joint groove of the second connecting part, so that the joint part can be bent once with the first connecting part, and the second connecting part and the joint part can also be bent once. In this way, when one of the first connecting part and the second connecting part is connected to the wrench body and the other is used as a socket, the socket and the wrench body can be bent twice, so the bending angle between the socket and the wrench body is larger than that of the existing products. Therefore, compared with the existing products, the present invention does further improve the bending angle of the socket relative to the hand body.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A multi-section bending joint comprises: a joint member having a rod portion, wherein two ends of the rod portion are respectively connected to a first spherical head and a second spherical head; a first connecting member, wherein two opposite ends of the first connecting member are respectively a first connecting portion and a first joint groove, wherein the first spherical head is located in the first joint groove; and a second connecting member, wherein two opposite ends of the second connecting member are respectively a second connecting portion and a second joint groove, wherein the second spherical head is located in the second joint groove.

[0008] Furthermore, the bending angle between the joint component and the first connecting component can be 0 degree to 22.5 degrees.

[0009] Furthermore, the bending angle between the joint component and the second connecting component can be 0 degree to 22.5 degrees.

[0010] Furthermore, the bending angle between the joint component and the first connecting component can be 0 degree to 45 degrees.

[0011] Furthermore, the bending angle between the joint component and the second connecting component can be 0 degree to 45 degrees.

[0012] The beneficial effect of the present invention is that it utilizes a structure in which the joint part has a first spherical head and a second spherical head at both ends to improve the existing problem. Since the joint part has a first spherical head and a second spherical head at both ends, the first spherical head and the second spherical head can be respectively assembled in the first joint groove of the first connecting part and the second joint groove of the second connecting part, so that the joint part can be bent once with the first connecting part, and the second connecting part and the joint part can also be bent once. In this way, when one of the first connecting part and the second connecting part is connected to the wrench body and the other is used as a socket, the socket and the wrench body can be bent twice, so the bending angle between the socket and the wrench body is larger than that of the existing products. Therefore, compared with the existing products, the present invention does further improve the bending angle of the socket relative to the hand body. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] To understand the embodiments of the present invention in more detail, please refer to the accompanying drawings. Figures 1 to 5 The present invention provides a multi-section bending joint, which includes: a joint part 1, which has a rod part 11, and the two ends of the rod part 11 are respectively connected to a first spherical head 12 and a second spherical head 13; a first connecting member 2, the two opposite ends of the first connecting member 2 are respectively a first connecting part 21 and a first joint groove 22, and the first spherical head 12 is located in the first joint groove 22; and a second connecting member 3, the two opposite ends of the second connecting member 3 are respectively a second connecting part 31 and a second joint groove 32, and the second spherical head 13 is located in the second joint groove 32.

[0046] The first spherical head 12 is arranged in the first joint groove 22 in such a way that the first spherical head 12 is completely immersed in the first joint groove 22, and the first connecting member 2 has a first through hole 23 that passes through the first joint groove 22 and the outer wall surface, and the aperture of the first through hole 23 is slightly reduced near the opening of the first joint groove 22, so that when the first anti-dropping bead 25 is placed in the first through hole 23, the first anti-dropping bead 25 is only slightly exposed in the first joint groove 22, thereby limiting the first spherical head 12 from escaping from the first joint groove 22 , the first connecting member 2 is connected to the outer periphery of the first through hole 23 with a first buckle 24 to prevent the first anti-falling bead 25 from falling out from the outside, and a first spring 26 is arranged between the first spherical head 12 and the deepest part of the first joint groove 22 to stabilize the bending angle between the first spherical head 12 and the first connecting member 2, and the second spherical head 13 is arranged in the second joint groove 32 in the same way as mentioned above to complete the installation by using the second through hole 33, the second buckle 34, the second anti-falling bead 35, and the second spring 36.

[0047] The first spherical head 12 has a plurality of curved surfaces around its circumference, so that the outer contour of the first spherical head 12 is polygonal. For example, a hexagon is used as an example in this embodiment, but it can actually be a quadrilateral, a dodecagon, etc. The structural design of the second spherical head 13 is the same as that of the first spherical head 12.

[0048] The above content further describes the implementation mode of the present invention. The present invention improves the existing problem by using the structure that the joint component 1 has a first spherical head 12 and a second spherical head 13 at both ends. Since the joint component 1 has a first spherical head 12 and a second spherical head 13 at both ends, the first spherical head 12 and the second spherical head 13 can be assembled in the first joint groove 22 of the first connecting member 2 and the second joint groove 32 of the second connecting member 3, respectively. Figure 4 As shown, the joint part 1 can be bent once with the first connecting part 2, and Figure 5 As shown, the second connecting member 3 and the joint member 1 can also be bent once, and in this embodiment, Figure 6 , Figure 7 What is presented is an example in which the first connecting portion 21 of the first connecting member 2 is connected to the mounting portion 101 of the wrench body 100, and the second connecting portion 31 of the second connecting member 3 is used as a socket for connecting the target object 200. Since the second connecting member 3 used as a socket and the wrench body 100 are bent twice, the bending angle between the second connecting member 3 used as a socket and the wrench body 100 is larger than that of existing products. Compared with existing products, the present invention does further improve the bending angle of the socket relative to the wrench body, which is novel and progressive.

[0049] In addition, the first and second described in this specification are used to facilitate the understanding of the content of the present invention, and can actually be changed according to design requirements and implementation methods.

[0050] Further Figure 4 As shown, the bending angle θ1 between the joint component 1 and the first connecting component 2 can be 0 degrees to 22.5 degrees. Figure 5 As shown, the bending angle θ2 between the joint component 1 and the second connecting component 3 can be 0 degrees to 22.5 degrees. In this way, a maximum angle of 45 degrees can be generated between the second connecting component 3 and the first connecting component 2, which is twice the bending angle of the previous single-stage bending structure.

[0051] Further Figure 4 As shown, the bending angle θ1 between the joint component 1 and the first connecting component 2 can be 0 degrees to 45 degrees. Figure 5 As shown, the bending angle θ2 between the joint part 1 and the second connecting part 3 can be 0 degrees to 45 degrees, so that a maximum angle of 90 degrees can be generated between the second connecting part 3 and the first connecting part 2. The first spherical head 12 and the second spherical head 13 of the present invention only need to change the curvature of their circumferential curved surfaces in implementation to produce a larger bending angle, and the two-stage bending method can produce twice the bending angle compared to the previous single-stage bending structure.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
