Description

Adjustable wrench structure

This creation is about the “improvement of the structure of the adapter wrench”, especially the creation of an adapter wrench suitable for a construction site with a narrow operating space.

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. It can mesh the teeth on the outside of the gear to further determine that the head unidirectionally circulates around the gear, and reversely drives the gears to rotate synchronously for outputting torque.

In this way, the ratchet wrench is driven by the head, so that the gears rotate synchronously, and when a certain amplitude is reached, it is reversely idling, so that the user can continue to apply force.

However, in some work situations, especially in the construction site where the operation space is narrow, due to the limitation of the rotational position, the user feels difficult to use; therefore, the lack of the aforementioned conventional structure It is necessary to further improve it.

In view of the fact that the current structure still has improvement, the creator has been engaged in the multi-year production and sales experience of related products, and has focused on improving the existing problems. After many improvements and tests, he finally created a turn. The structure of the wrench is improved.

Therefore, the main purpose of this creation is to provide a suitable space for operation. At the construction site, the structure of the adapter is simple and convenient to use.

Another object of the present invention is to provide a time-saving and labor-saving adapter wrench structure improvement.

In order to achieve the above object, the present invention proposes an improvement of the adapter wrench structure, which includes: a first handle, the handle has a head having a first accommodating space and a second accommodating space, wherein the first and second accommodating spaces respectively have a hole; a first gear having a first operating portion in the center of the top surface of the first gear, and a first column in the center of the bottom surface of the first gear, and the first gear system is disposed in the first receiving space , the first column of the first gear is received in the hole; a second gear has a second column at the center of the top surface of the second gear, and a second operating portion is disposed at a center of the bottom surface of the second gear, and the second gear is disposed in the second receiving space Having the second operating portion of the second gear received in the hole and engaging the second gear with the first gear; a cover plate having a first hole and a second hole respectively, and the cover plate is fixed on the top surface of the head of the handle, and the first hole is for the first gear The first operating portion is threaded out, and the second hole is received by the second post of the second gear.

The first and second operating portions are quadrangular cylinders.

Wherein the second gear has fewer teeth than the first gear.

The following description of the preferred embodiment of the present invention is further described below in order to enable those skilled in the art to practice the present invention to be implemented in accordance with the present specification.

First, with reference to the first to sixth figures, the present invention is an improved structure of the adapter wrench, comprising: a handle 10 having a head 11 at one end thereof and two connected ends in the head 11 The first accommodating space 12 and the second accommodating space 13 respectively have a hole 14 at a set position of the first and second accommodating spaces 12 and 13; a first gear 20 and a top surface of the first gear 20 The first gear 20 is disposed in the center of the bottom surface of the first gear 20, and the first gear 20 is disposed in the first accommodating space 21 to make the first gear 20 The first column 22 is received in the hole 14; a second gear 30 has a second column 31 at the center of the top surface of the second gear 30, and a second operation is provided at the center of the bottom surface of the second gear 30. Part 32, and the second tooth The wheel 30 is mounted in the second accommodating space 13 so that the second operating portion 32 of the second gear 30 is received in the hole 14 and the second gear 30 is engaged with the first gear 20 a cover plate 40, the cover plate 40 has a first hole 41 and a second hole 42 respectively, and the cover plate 40 is fixed on the top surface of the head 11 of the handle 10, and the first cover A hole 41 is provided for the first operating portion 21 of the first gear 20 to be received, and the second hole 42 is received by the second post 31 of the second gear 30.

The first and second operating portions 21 and 32 are quadrangular cylinders.

The second gear 30 has fewer teeth than the first gear 20 .

With the above combination, please continue to refer to the first to sixth figures. When the user wants to use this creation to tighten or loosen the screw (not shown), only one The sleeve 50 is mounted on the first operating portion 21 of the first gear 20 and is mounted on the second operating portion 32 of the second gear 30 by another sleeve 60. The sleeve 60 can then be coupled by a ratchet wrench 70. (As shown in FIG. 6), the second gear 30 is rotated, and the second gear 30 can synchronously rotate the first gear 20 to rotate the first operating portion 21 of the first gear 20 to drive the sleeve 50. The lock member is screwed or unscrewed, and since the number of teeth of the second gear 30 is less than the first gear 20, when the user drives the second gear 30, the first gear 20 can be quickly and easily rotated, and quickly Complete the purpose of the operation rotation.

This creation is very suitable for use in a narrow operating space, or in a space where the cornering operation space is limited. The user can hold the handle 10 of the creation in one hand, the ratchet wrench 70 in the other hand, and the single wrench by the ratchet wrench 70. Operate, and use the second gear 30 to synchronously rotate the first gear 20 to make it effectively and quickly transfer the force end, that is, the force end It is not the same axis (as shown in the seventh to eighth figures). It is very suitable for use in some workplaces, especially for construction sites with narrow operation space. It is simple and convenient to operate and practical.

In summary, the structure of the transfer wrench is improved, and the various shortcomings of the conventional structure are effectively improved, and the main technical means of the creation are not found in any related publications, and the application requirements of the new patent are met. To file an application, the Department of Health is requested to grant the patent right.
