The present disclosure relates to a sleeve structure. More particularly, the present disclosure relates to a sleeve structure that can grip a working tool to form a working tool assembly.
With the development of science and technology, when operating tools such as screws, the users often use a sleeve to engage the tool to increase the convenience of operation. However, when using the sleeve to engage the tool, the tool is often fallen off from the sleeve due to the excessive force exerted by the users, resulting in a waste of time.
At present, many sleeves that are convenient for the users to operate have been launched on the market, and in order to increase the stability of the sleeve engaging the tool, many accessories used with the sleeve have been developed, but the additional manufacturing costs are often increased.
Therefore, how to improve the gripping effect and the stability of the sleeve for gripping the tool, which is the goal of the relevant industry.
According to one aspect of the present disclosure, a sleeve structure includes a sleeve body, a tooth structure, a stopping structure, an elastic component and a resisting component. The sleeve body has a central axis, and includes an opening hole, the opening hole is opened at one end of the sleeve body. The tooth structure is disposed around an inner wall of the sleeve body, and the tooth structure includes a first groove and a second groove. The first groove is disposed around the tooth structure. The second groove is disposed around the tooth structure, and the first groove is closer to the opening hole than the second groove. The stopping structure is disposed around the inner wall of the sleeve body, and the stopping structure is farther from the opening hole than the tooth structure. The stopping structure includes a through hole and an inner surrounding wall. The through hole corresponds to the opening hole and is passed through the inner surrounding wall. The elastic component is disposed in the first groove and slightly protruded from the first groove. The resisting component is disposed in the second groove and protruded from the second groove toward a direction of the central axis.
According to another aspect of the present disclosure, a working tool assembly includes a sleeve structure and a working tool. The sleeve structure includes a sleeve body, a tooth structure, a stopping structure, an elastic component and a resisting component. The sleeve body has a central axis, and includes an opening hole, the opening hole is opened at one end of the sleeve body. The tooth structure is disposed around an inner wall of the sleeve body, and the tooth structure includes a first groove and a second groove. The first groove is disposed around the tooth structure. The second groove is disposed around the tooth structure, and the first groove is closer to the opening hole than the second groove. The stopping structure is disposed around the inner wall of the sleeve body, and the stopping structure is farther from the opening hole than the tooth structure. The stopping structure includes a through hole and an inner surrounding wall. The through hole corresponds to the opening hole and is passed through the inner surrounding wall. The elastic component is disposed in the first groove and slightly protruded from the first groove. The resisting component is disposed in the second groove and protruded from the second groove toward a direction of the central axis. The working tool is combined with the sleeve structure, and the working tool includes an abutting portion. A shape of the abutting portion corresponds to a shape of the tooth structure. When an abutting width of the abutting portion is L1, an abutting thickness of the abutting portion is L2, the following condition is satisfied: 0.1 ≤ L2/L1 ≤ 0.63.
The present disclosure can be more fully understood by reading the following detailed description of the embodiment, with reference made to the accompanying drawings as follows:
The embodiments of the present disclosure will be described below by referring to the figures. For clarity, many practical details will be explained in the following description. However, the readers should realize that these practical details are not limited to the present disclosure. That is, in some embodiments of the present disclosure, the practical details are not necessary. In addition, in order to simplify the figures, some of the conventional structures and elements will be shown in the figures with simplified schematic; and the repeated elements will be shown by the same reference numerals.
Furthermore, in the present specification, when one element (or, structure and module) “is connected to”, “is disposed on” or “is linked to” another element, it means the element can be directly connected to, disposed on or linked to another element or be indirectly connected to, disposed on or linked to another element (that is, there is an element disposed between the aforementioned element and another element). In other words, if an element is exactly illustrated as being “directly connected to”, “directly disposed on” or “directly linked to” another element, there is without an element disposed between the aforementioned element and another element. Furthermore, the terms of “first”, “second” and “third” are only for illustrating different elements or components and not used to limit the elements or components themselves. Thus, the first element/component can be named as the second element/component. Moreover, the combination of the elements/component/structures/modules described in the present specification are not well-known, conventional or common combination in the field, and it is hard for the person skilled in the arts to determine whether the combination relationship is obviousness or not based on the elements/components/structures/modules themselves are conventional or not.

In particular, the sleeve body 110 has a central axis X, and includes an opening hole 111. The opening hole 111 is opened at one end of the sleeve body 110. The tooth structure 120 is disposed around an inner wall 112 of the sleeve body 110, and includes a first groove 121 and a second groove 122. The first groove 121 and the second groove 122 are disposed around the tooth structure 120, and the first groove 121 is closer to the opening hole 111 than the second groove 122. The stopping structure 130 is disposed around the inner wall 112 of the sleeve body 110, and the stopping structure 130 is farther from the opening hole 111 than the tooth structure 120. The stopping structure 130 includes a through hole 131 and an inner surrounding wall 132, wherein the through hole 131 corresponds to the opening hole 111 and is passed through the inner surrounding wall 132.

The resisting component 150 is disposed in the second groove 122 and protruded from the second groove 122 toward a direction of the central axis X. Therefore, when a working tool (not shown) is inserted in the sleeve structure 100 from the opening hole 111, the sleeve structure 100 can grip the working tool by the elastic component 140, and block the working tool from entering the inner space of the sleeve structure 100 by the resisting component 150.
In the embodiment of
Furthermore, a distance between the first groove 121 and the stopping structure 130 is smaller than a distance between the first groove 121 and the opening hole 111 of the sleeve body 110. The elastic component 140 is used for gripping the working tool, and the gripping ability of the elastic component 140 can be increased by the distance relationship between the first groove 121 and the stopping structure 130. Moreover, the elastic component 140 can be but not limited to a C-shaped ring, which can increase the uniformity of the elastic component 140 for gripping the working tool, and facilitate the assembly of the elastic component 140.
