Description

Ratchet wrench set

The present invention relates to a ratchet wrench set, which is a hand tool used for tightening and loosening a target object (such as a screw).

A wrench is a very common hand tool, generally used to loosen and tighten screws, nuts, etc. However, common open-end wrenches require a larger operating space to be used smoothly and continuously. If used in a small room, it will be restricted by the environment. After the wrench is swung at a slight angle, it must be removed, and then the screw must be put back on to turn it, which is quite time-consuming. Therefore, the relevant technical field has further developed a ratchet wrench, which allows users to keep turning the wrench without removing it from the screw, which is very convenient to use in a small environment.

There are many kinds of wrenches available on the market for users to choose according to different situations. For example, there are ratchet wrenches that can be used for fast reciprocating operations in narrow spaces, socket extension wrenches that can be used in deep construction areas, and T-type wrenches that are used when greater construction force is required. However, construction workers often have to carry a variety of wrenches, which leads to the problem of carrying too much weight.

In view of the above problems, it is necessary to reduce the weight burden of wrenches carried by construction workers.

The present invention utilizes a structural design of a through hole with a twelve-pointed star-shaped opening and a hexagonal opening, so that when a construction piece with a hexagonal rod is inserted from one end of the star-shaped opening, if the rod is aligned with the corners of the hexagonal opening, it can pass through the through hole, thereby forming a T-shaped wrench. When the rod is further rotated 30 degrees, the rod can be inserted into the star-shaped opening but cannot pass through the through hole. This situation In this state, the present invention will present the form of a socket extension wrench. Combining the above content, it can be known that in practice, it is only necessary to switch the combination mode of the present invention and the construction piece and the switchable wrench type, so as to reduce the total weight of the wrench that the construction personnel need to carry. The present invention has indeed improved the problem that the construction personnel used to carry too heavy wrenches. The present invention is indeed novel and progressive.

To achieve the above-mentioned purpose and effect, the present invention provides a ratchet wrench set, which includes: a wrench, whose two ends are respectively a head and a working part; a ratchet, which is inserted into the head of the wrench, the ratchet includes a through hole, an annular groove, and a side opening, the side opening is located at the position of the ratchet having the annular groove, the through hole and the annular groove are connected with the side opening, one end of the through hole is a star-shaped opening with twelve corners with each angular position interval differing by 30 degrees, and the other end is a hexagonal opening with six angular positions corresponding to the star-shaped opening with intervals differing by 60 degrees; a C-shaped buckle, which is buckled in the annular groove, and a part of the C-shaped buckle corresponding to the side opening is located in the through hole.

In order to understand the implementation and effect of the present invention in more detail, please also watch with the drawings. As shown in the first to ninth figures, the present invention is a ratchet wrench set, which includes: a wrench 1, whose two ends are respectively a head 11 and a working part 12; a ratchet 2, which is penetrated through the head 11 of the wrench 1, and the ratchet 2 includes a through hole 21, an annular groove 22, and a side opening 23, and the side opening 23 is located at the ratchet 2 having the annular groove. The through hole 21 is connected to the annular groove 22 via the side opening 23. One end of the through hole 21 is a star-shaped opening 211 with twelve corners, each of which is spaced 30 degrees apart, and the other end is a hexagonal opening 212 with six corners corresponding to the star-shaped opening 211 and spaced 60 degrees apart. A C-shaped buckle 3 is buckled on the annular groove 22, and a portion of the C-shaped buckle 3 corresponding to the side opening 23 is located in the through hole 21.

There is also a construction member 4, which includes a connected rod 41 and a construction head 42. The rod 41 is hexagonal. When the rod 41 is aligned with the hexagonal opening 212, the rod 41 can movably pass through the through hole 21. When the rod 41 is inserted into the through hole 21 but not aligned with the hexagonal opening 212, the rod 41 cannot pass through the through hole 21.

The implementation method of the present invention is further described in detail following the above contents. It can be known from the above contents and the third and fourth figures that the present invention utilizes the structural design of the through hole 21 having a twelve-pointed star-shaped opening 211 and a hexagonal opening 212, so that when a construction piece having a hexagonal rod 41 is inserted from one end of the star-shaped opening 211 as shown in the fifth and sixth figures, if the corners of the rod 41 and the hexagonal opening 212 are aligned, it can pass through the through hole, thereby forming a T-shaped wrench. When the rod is further rotated 30 degrees so that the hexagon of the rod 41 cannot correspond to the hexagonal opening 212, as shown in the seventh figure, the rod 41 can be inserted into the star-shaped opening 211 but cannot pass through the through hole 21. , and the portion of the C-shaped buckle 3 located in the through hole 21 is pushed open by the rod 41, which will generate a clamping force on the rod 41 to make the insertion of the rod 41 more stable. In this state, the present invention will present the appearance of a socket extension wrench. Combining the above content, it can be seen that in practice, it is only necessary to switch the combination of the ratchet 2 and the construction piece 4 of the present invention and the type of switchable wrench 1, so as to reduce the total weight of the wrench 1 that the construction personnel need to carry. The present invention does improve the known problem that the construction personnel used to carry too heavy a wrench. The present invention is indeed novel and progressive.

A combination of a ratchet 2 and a wrench 1 is further disclosed, wherein the ratchet 2 includes a wide diameter section 24 and a narrow diameter section 25 connected to each other, the through hole 21 penetrates the wide diameter section 24 and the narrow diameter section 25, the narrow diameter section 25 penetrates the head 11 disposed on the wrench 1, the annular groove 22 is located at the position where the side opening 23 penetrates the narrow diameter section 25, and the head 11 is sandwiched between the wide diameter section 24 and the C-shaped buckle 3.

The present invention further discloses a C-shaped buckle 3 , wherein the C-shaped buckle 3 includes an arc segment 31 and a straight segment 32 connected to each other, and a portion of the straight segment 32 is located in the through hole 21 .

The above is only used to explain the preferred embodiments of the present invention, and is not intended to limit the present invention in any form. Therefore, any modifications or changes made to the present invention under the same spirit of the invention, which are other forms that can be implemented and have the same effect, should still be included in the scope of protection intended by the present invention.

In summary, the "ratchet wrench set" of the present invention is indeed fully in line with the needs of industrial development in terms of practicality and cost-effectiveness, and the disclosed structural invention is also an unprecedented innovative structure, so there is no doubt that it is "novel". In addition, the present invention can improve the effectiveness of the commonly used structure, so it is also "progressive". It fully complies with the provisions of the application requirements of invention patents under the Patent Law of our country. Therefore, a patent application is filed in accordance with the law, and we sincerely request the Jun Bureau to review and affirm it as soon as possible.
