Description

Ratchet wrench construction

The creation system is related to a ratchet wrench structure, in particular, the control unit of the ratchet wrench structure can be pivoted at the third cavity by the first abutment surface limitation of the second cavity, and the twisting structure is convenient. Made by various methods.

As previously known by us, the conventional ratchet wrench construction, such as the US patent application number: 12/828315, certificate number: 7121170, Taiwan patent application number: 093200216, certificate number: M254305, patent name: ratchet wrench dial structure, The patented structure is: a dialing structure of a ratchet wrench, the ratchet wrench is mainly formed with a larger head 51 at the end of a handle 50, and a head 60 and a tool head are accommodated in the head 51. The ratchet block 65 and the ratchet block 65 are moved by a dial structure of the dial block 70; the dial block 70 of the dial structure is formed with a corresponding slot 71 corresponding to the ratchet block 65, and the dial block 70 is further provided. A positioning piece 75 is provided in the through slot 71. The positioning piece 75 is formed with two upper and lower corresponding slots 76 in the center of the rear portion of the positioning piece 75, and a guide piece 77 is formed between the two slots 76. The positioning piece 75 can be sleeved with a supporting spring 78 by the guiding piece 77, so that the positioning piece 75 can be stably supported on the ratchet block 65; thereby forming a ratchet wrench with a smooth and accurate positioning. Bit structure.

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

1. Please refer to Figure 3 of the U.S. Gazette, the dial 70 is provided with a through groove 71, a buckle groove 72 and a turn The disk 79, when the dial block 70 is formed, can only select the powder unpressed or the powder unejamping method, and the dial 70 is limited by the shape of the through groove 71, the buckle groove 72 and the turntable 79, and can only be opened before and after the mold. The upper and lower molds are opened, and the front and rear mold opening manners make the dial block 70 more difficult to mold. The cost of the dial block 70 is higher. If the dial block 70 is formed, the processing machine system cannot process the structure of the through groove 71. The dial block 70 molding method is limited.

2. The bottom of the dial block 70 is provided with a buckle groove 72, and a limit spring 73 is provided. The limit spring 73 is fastened to the buckle groove 72, so that the dial block 70 can be pivoted to the handle bar 50. At the block receiving groove 54, the block 70 is required to be pivoted at the dial pocket 54 by the limit spring 73, so that the cost of the limit spring 73 is increased.

In view of the lack of the above-mentioned conventional patented ratchet wrench, the creator has been engaged in the manufacturing experience of related industries for many years, and finally has a product that can solve the drawbacks of the ratchet wrench structure.

A new type of problem to be solved: the conventional ratchet wrench has the limitation of the manufacturing rule of the dial block. The ratchet wrench structure of the present system is provided with a control unit, which can be restricted by the first abutment surface of the second cavity.
