Description

Bicycle middle shaft split wrench tool

This creation department relates to a disassembling wrench tool for a bicycle center shaft, especially a wrench tool which can simultaneously disassemble a plurality of bicycle center shafts and achieve a simple and easy operation.

According to the wrench main body 10, the main shaft 1 of the bicycle is removed or assembled by the five-way pipe. As shown in FIG. 1 , most of the handles 11 are provided with a single-size wrenching port 12 at one end of a handle 11 for The bicycle center shaft 1 is disassembled or assembled. However, the conventional wrench body 10 can only be applied to a bicycle shaft 1 of a predetermined specification. If a bicycle center shaft of another different specification is to be disassembled, another basic configuration must be taken. The main body of the wrench with different handles and different diameters is not only troublesome to operate, but also time-consuming and labor-intensive and less efficient in operation, and it has not been able to provide various central axes with simple tools at the same time. The effect of splitting.

In view of the above-mentioned shortcomings of the above-mentioned practices, the author has exhausted his mind to study and design carefully, and has been adhering to the creative spirit of perseverance. After many discussions and trials and full improvement of the concept and improvement, the author has launched this creation.

The main purpose of the present invention is to provide a disassembling wrench tool for a bicycle center shaft, in particular, the main system of the wrench is provided with a wrench having a non-slip pattern on both sides of the surface for the operator to have a better grip effect on the hand. a handle, and one of the first tooth groove collars is disposed on one side of the wrench handle The sleeve end, the other side of the extension end is provided with a set of upper and lower sleeve sleeves formed by the second and second slotted ring sleeves, and the sleeve end is sleeved The second slotted ring sleeve and the third slotted ring sleeve of one of the slotted ring sleeve and the sleeved wrench are respectively provided with three kinds of perforation calibers, and can be respectively used for the fitting of three kinds of bicycle middle shafts of different size and size. In this way, it is easier, easier and more efficient to work with the hand-tool for the bicycle shaft maintenance work.

Please refer to FIG. 2 (please refer to FIG. 3 at the same time). The present invention provides a wrench tool for disassembling and assembling a bicycle center shaft. The wrench body 20 is provided with a non-slip pattern 211 formed on both sides of a surface. For the operator's hand, the wrench handle 21 with a better gripping effect is turned on, and one end of the wrench handle 21 is provided with a sleeve end 22 of the first toothed ring sleeve 221, and the other side is extended with a set of joints. The end 24 is sleeved with a sleeve 23 having a second and second slotted collar 231 and a third slotted sleeve 232, and the first slotted sleeve 221 and the sleeve of the sleeve 22 The second slotted ring sleeve 231 and the third slotted ring sleeve 232 of the head 23 are respectively provided with three kinds of perforation calibers, and can be used for the combination of three types of bicycle shafts 2, 2A and 2B of different sizes. And the set of 23 sets A plurality of engaging blocks 233 may be disposed around the outer side of the one end, and a plurality of engaging grooves 241 are disposed at opposite positions in the inner periphery of the socket end 24, and the engaging block 233 and the engaging groove 241 are welded by means of welding. The welding knot is fixed, and at an appropriate position of the wrench handle 21, an auxiliary rotating member 26 for taking out the outer cover of the bicycle middle shaft 2, 2A, 2B can be disposed.

When the user wants to disassemble or assemble the bicycle shaft, the operator can hold the wrench main The wrench handle 21 of the body 20 is provided with the first, second and third slotted collars 221, 231, 232 of different diameters by using the sleeve end 22 and the sleeve 23 on both sides of the wrench handle 21 The bicycle shaft 2 (as shown in Figure 4), 2A (as shown in Figure 5), and 2B (shown in Figure 6) of the size of the bicycle can be used to make the bicycle shaft 2, 2A, 2B After the first, second, and third slotted sleeves 221, 231, and 232 of the end 22 or the sleeve 23 are rotated, the bicycle five-way tube can be disassembled or disassembled or assembled, thereby achieving operation. The maintenance work using the hand tool can be more simple and easy, and the convenience of the selection tool can be greatly improved and the work efficiency can be improved.

In summary, when the knowledge of this creation can be widely used by related industries, and this In order to comply with the provisions of the Patent Law before the application, the company filed a new type of patent application according to law, and asked the bureau to inspect the patent and benefit the patent.

However, the above is only one of the possible embodiments of this creation. When it is not possible to limit the scope of the implementation of this creation, that is, the characteristics and spirit of the application as described in the scope of this application are equally changed or modified. It is still covered by this creation patent.
