Description

Wrench structure improvement

This creation is about a "wrench structure improvement", especially a wrench that is suitable for loosening or tightening bolts of different sizes.

According to the conventional hand tool structure, there are many kinds of common tools; the common ratchet wrench is equipped with a gear in the hollow head, and a claw-shaped click structure is additionally installed in the head, which is made by the arrangement of the cassette structure. The teeth of the gear can be meshed to further determine that the head idly rotates around the gear, and the gears are driven to rotate synchronously for outputting torque. Thus, the ratchet wrench is driven by the head, so that the gears rotate synchronously and reach a certain amplitude. It is necessary to reverse the idling so that the user can continue to apply force.

However, the conventional ratchet wrench is not only complicated in structure, but also not easy for the user to assemble. Moreover, the ratchet wrench needs to be matched with sleeves of different sizes to loosen or tighten the bolts of different sizes; Therefore, the lack of the above-mentioned conventional structure is necessary to further improve it.

In view of the fact that there are still some improvements in the current structure, the creator has been engaged in the multi-year production and sales experience of related products, and has been thinking about the existing problems and pondering the improvement methods. After many improvements and tests, he finally created a wrench. Structural improvement.

Therefore, the main purpose of the present invention is to provide a wrench structure improvement that is not only simple in structure, easy to assemble, but also simple in operation.

Another object of the present invention is to provide a structural improvement of a wrench suitable for loosening or tightening bolts of different sizes.

In order to achieve the above object, the present invention proposes a structural improvement of a wrench, comprising: a body, the top mask of the body has a receiving space, and the two ends of the body respectively have a head with an operating hole, and each operating hole Separatingly with the accommodating space, the body has a first through slot at a set position of the accommodating space; a screw having an external thread at a position of the middle portion of the screw, and the screw system is disposed on the body a accommodating space; a rotating member, the rotating member is screwed on the external threaded portion of the screw, and the rotating member is located in the first through slot of the body; a cover body opposite to the body The first slotting position is provided with a second through slot, and the cover system is locked on the top surface of the body, so that the rotating member can protrude the second through slot.

Wherein, the rotating member is a screw sleeve with an internal thread portion, and the outer periphery of the screw sleeve has a slip preventing pattern.

The apertures of the operating holes at both ends of the body are apertures of different sizes.

The operating hole of the body is a polygonal hole.

The operating hole of the body is a hexagon socket.

Among them, the system is long strips.

The following is further described below with reference to the drawings of the preferred embodiment of the present invention, with a view to Those who are familiar with the technology related to this creation may be implemented in accordance with the statements in this manual.

First, with reference to the first to eighth figures, the present invention is an improved wrench structure, comprising: a body 10, the body 10 is elongated, and the top mask of the body 10 has a receiving space. The two ends of the main body 10 respectively have a head portion 12 of the operation hole 121. The operation holes 121 are respectively communicated with the accommodating space 11 , and the body 10 has a position at the set position of the accommodating space 11 . a first slot 111; a screw 20 having an external thread portion 21 at a position of the screw 20, and the screw 20 is received in the receiving space 11 of the body 10; a rotating member 30, the rotating member 30 The screw is disposed on the external threaded portion 21 of the screw 20, and the rotating member 30 is located in the first through slot 111 of the body 10; A cover 40 is disposed on the first slot 111 of the body 10, and a second slot 41 is defined. The cover 40 is locked to the top surface of the body 10 to enable the rotating member 30. The second through groove 41 is exposed.

The rotating member 30 is a screw sleeve with an internal thread portion (not shown), and the outer periphery of the screw sleeve has a slip preventing pattern 31.

The apertures of the operation holes 121 at both ends of the body 10 are apertures of different sizes.

The operation hole 121 of the body 10 is a polygonal hole.

The operation hole 121 of the body 10 is a hexagon socket.

With the above combination, please continue to refer to the first to eighth figures. When the user wants to use this creation to tighten or loosen the bolt (not shown), only one end of the body 10 is required. The operation hole 121 is sleeved on the head 50 of the bolt, and then the user can rotate the rotation member 30 to rotate the rotation member 30 to drive the screw 20 to the operation hole 121 of the body 10 until the end of the screw 20 is reached. After tightening the head 50 of the bolt (as shown in the sixth figure), the user can then use the long body 10 as the force arm for the force application, and then turn the bolt, so that the bolt can be tightened or loosened. The operation is not only simple in structure, easy to assemble, but also simple and convenient to operate, and practical.

In addition, the present invention is applicable to the head 50 of bolts of different sizes, as shown in the seventh and eighth figures, and the operation mode thereof is also as described above, and the overall use is simple, and is suitable for the heads of bolts of different sizes. It is convenient and practical.

In summary, the structure of the creative wrench is improved, effectively improving the various shortcomings of the conventional structure, and the main technical means of the creation are not found in any related publications. In accordance with the application requirements of the new patent, the application shall be filed in accordance with the law, and the application for patent rights shall be granted by the bureau.
