Description

Wrench and double gauge sleeve combination device

The invention provides a device for combining a wrench with a double-size sleeve, which specifically refers to a technical field in which the sleeve has the function of facilitating the connection of the wrench and has better structural properties.

Generally, the sleeve is mainly provided with a hexagonal sleeve hole at one end and a square joint hole at the other end, and the sleeve hole is a screw-locking component (nut or bolt head) of a matching size. The coupling hole is a wrench joint assembly whereby the wrench can be tightened through the sleeve to secure the coupling or fastening function in the mechanical structure or building component.

Since the sleeve has only a single-sized sleeve hole, it can only be applied to a single-size screw-locking element, which makes it necessary for us to prepare ten sets of sleeves of different sizes to be sufficient, which is quite space-consuming and unacceptable. In addition, it also increases the inconvenience that we have to change the different sleeves one by one.

Therefore, there is a kind of "Structural Improvement of the Sleeve" as disclosed in China's Announcement No. 256148, which mainly has two sleeve holes of similar size coaxially recessed at one end of the sleeve, and a square joint hole at the other end. The two sets of holes can provide two kinds of similar screw-locking component inserts to simplify the number of sets of sleeves. However, the sleeve is limited by the structural design and cannot integrate the two large differences in size. The fit hole has its limitations in configuration, and it also makes it difficult for us to distinguish between the two sets of hole sizes.

As for the invention patent No. I359061 of the "Double-Specific Sleeve" invention, the size limitation of the 256148 patent case can be improved. According to the two-size different size, the sleeve hole is integrated into one end of the sleeve, and is not similar in size. Restriction, however, the structure of the invention patent is not streamlined, resulting in a price that is not economical. More importantly, the two different sizes of the sleeve holes are also provided at one end of the sleeve, and the visibility is not easy. problem.

In view of this, the inventors have proposed a device in which a wrench and a double-size sleeve are combined, thereby simultaneously eliminating the many problems in the use of the prior patents.

The main content of the present invention is to provide a device for combining a wrench and a double-size sleeve, comprising: a wrench having a driving hole penetrating therethrough; a sleeve having a first end and a second end opposite to each other The first end is concavely provided with a first sleeve hole capable of driving the screw lock component, and the second end is recessed with a second sleeve hole, the second sleeve hole diameter is larger than the first sleeve hole pitch diameter, It is capable of driving another large-sized screw-locking element, and the outer circumference of the sleeve is provided with a tilting portion matched with the driving hole, and one end of the tilting portion can extend with the first end or the second end of the sleeve. So that the swaying portion can be detachably coupled in the driving hole in the axial direction; and a fastening device, which is used as the cocking portion, cannot be easily taken out of the driving hole.

The present invention has the following advantages:

1. The sleeve of the invention has two first and two sets of different holes corresponding to the two sizes corresponding to the two ends of the sleeve, so that the similar size of the conventional one can be overcome, and it is important that the first and second sets of holes have the first and second sets of holes. The advantages of distinguishing between categories.

2. The outer diameter of the sleeve sway portion of the present invention is naturally larger than the conventional joint hole The diameter can be more easily inserted into the driving hole of the wrench, and the force applying area of the swaying portion can be larger than that of the conventional coupling hole, so that the cocking portion has a less deformable structure under the same stress state. .
