Transmission tool structure

The present invention relates to a transmission tool structure, comprising: a first system, a second receiving groove, and a second receiving groove; a first ratchet system is pivotally disposed in the first receiving groove and is provided a first tooth portion; a second ratchet system is pivotally disposed in the second cavity and is provided with a second tooth portion and meshes with the first tooth portion; a second system is coupled to the first body; The system has a rounded rod shape and is bonded to the second body.

As is known in the prior art, the conventional transmission tool structure, such as the U.S. Patent No. US Pat. No. 4,279,314, the patent name: ratchet wrench attachment, the structure of the patent is: a ratchet wrench attachment, mainly provided with: a first body The first body is provided with a first ratchet, a second ratchet and a third ratchet. The first ratchet is engaged between the second ratchet and the third ratchet, and the first ratchet, the second ratchet and the third ratchet The second portion of the second body is sleeved on the second sleeve portion; a wrench, the first sleeve portion of the wrench and the second body The bottom portion is sleeved; when the second body is rotated by the wrench, the third ratchet is rotated by the second body, and the first ratchet is rotated by the third ratchet, and the second ratchet is also subjected to The first ratchet engages and rotates.

However, the lack of structure of this patent is based on:

1. The first body interior is only provided with a first ratchet, a second ratchet and a third ratchet, the first The length of a body is not long. When the second body is rotated by a wrench, the torque of the wrench is very large, especially when the screw is to be screwed out by the screw hole, the torque of the wrench cannot be held by the hand. The first body is supported by the first body, and the automatic rotation loss is caused by the rotating torque of the wrench. Therefore, the first body needs to be provided with abutting bar against the wrench.

2. The length of the first body is not long. The structure of the patent is basically only used for the accessory tool of the wrench, that is, if the second sleeve of the third ratchet is fitted with a joint and the screw is screwed. When the hand is held on the first body, the rotational torque of the length of the first body is rather limited.

In view of the above-mentioned conventional patent transmission tool structure, the inventors have been engaged in the manufacturing and design experience of related industries for many years, and finally have a product that can solve the drawbacks of the transmission tool structure.

The conventional transmission tool is only a general tool accessory, and the invention has a relationship with a transmission tool structure, including: a first system having a first pocket, a second pocket and a through slot; a first ratchet The first hub is disposed in the first pocket and is provided with a first tooth portion; a second ratchet is pivotally disposed in the second pocket and is provided with a second tooth portion and meshes with the first tooth portion; The system is coupled to the first body; a third system is rounded and bonded to the second body.

A transmission tool structure includes: a first body, the first system is provided with a first receiving groove and a second receiving groove, wherein the first receiving groove and the second receiving groove are each a circular groove shape, the first a through slot is formed between the one and the second recess, and the through slot is The first pocket is in communication with the second pocket; the first ratchet is pivotally disposed in the first pocket, and the outer periphery of the first ratchet is provided with the first tooth of the annular array of teeth The first ratchet is provided with a first socket; a second ratchet is disposed in the second pocket, and the outer periphery of the second ratchet is provided with a second tooth of the annular array of teeth The second tooth portion is engaged with the first tooth portion at the through-groove, the second ratchet portion is provided with the second socket portion; a second body, the second body system is coupled to the first body; The third body, the third system is in the form of a long rod and is coupled to the second body.

When the transmission tool structure is sleeved and rotated by the first screwing member, the transmission tool structure can be extended to cooperate with a general ratchet wrench, and the transmission tool structure can be free from the limitation of insufficient rotation space. The second system is combined with the third body. When the ratchet wrench is rotated, the other hand can be held at the third body, so that the rotational torque of the ratchet wrench can be supported by the third body. The body does not have a rotation loss due to the rotational torque of the ratchet wrench.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention.
