Description

Ratchet wrench structure

The present invention is related to a ratchet wrench structure, and in particular to a ratchet wrench structure in which the ratchet only needs to be drilled with the second groove, and the manufacturing process of the ratchet is relatively simple and will not have cumulative tolerances.

As we know before, the commonly used ratchet wrench structure, such as Taiwan patent application number: 111209559, certificate number: M635472, patent name: torque tool quick release device, includes: a body, including a receiving hole, a connecting hole for assembling a driven part, and a through hole connecting the receiving hole and the connecting hole, the receiving hole and the connecting hole are respectively opened on two opposite sides of the body; a magnetic ring, fixed in the through hole; and a push rod, which can be relatively movably extended to penetrate the through hole and the magnetic ring.

However, the defects of this ratchet wrench structure are:

1. Please refer to Figure 4. When the main body 10 is processed and manufactured, first one end of the main body 10 must be drilled to form the receiving hole 11, and then the connecting hole 12 is drilled from the other end of the main body 10, and then the through hole 13 is drilled again at the connecting hole 12. The main body 10 is drilled three times and has two different directions of drilling. The main body 10 needs to be removed from the drilling machine and turned once before being assembled. The main body 10 has a complicated processing process, and the processing tolerance will be accumulated when the main body 10 is removed and assembled again.

2. The first flange 18 extending inward is provided at the edge of the hole 11. The first flange 18 can prevent the head 21 from escaping from the hole 11. However, the first flange 18 increases the processing procedures of the main body 10, and the punching machine is different from the drilling machine, and needs to be removed and assembled on the punching machine.

3. The magnetic ring 30 is assembled in the through hole 13 with a tight fit structure. The magnetic ring 30 is a magnetic structure and cannot have better strength. The magnetic ring 30 is easily damaged by mechanical pressure.

In view of the defects of the ratchet wrench structure in the above-mentioned conventional patent, the inventor, with many years of experience in the relevant industry, finally came up with a ratchet wrench structure product that can solve the conventional disadvantages.

In the conventional ratchet wrench structure, one end of the body must be drilled to form the receiving hole, and then the other end of the body must be drilled to form the connecting hole, and then the connecting hole must be drilled again to form the through hole, which is a complex process. In the ratchet wrench structure of the present invention, when the ratchet is manufactured, only the second receiving groove needs to be drilled, and the ratchet manufacturing process is simpler and will not have cumulative tolerances.

The present invention relates to a ratchet wrench structure, which includes: a main body having a first receiving groove; a ratchet wheel pivotally arranged in the first receiving groove, the ratchet wheel having a sleeve, a second receiving groove and a first abutment; a second main body assembled in the second receiving groove, the second main body does not come out of the second receiving groove, the second main body having a third receiving groove, a fourth receiving groove and a first abutment; A second abutment; a control rod is compatible with the second body, and the control rod is provided with a third abutment, a pressing portion, a rod body and a top surface; a magnetic block is accommodated in the second groove, and the magnetic block is accommodated between the second body and the first abutment. The magnetic block is limited by the second body, and the magnetic block does not escape from the second groove. The magnetic block is provided with a first through groove.

When manufacturing the ratchet, only the second groove and the first joint need to be drilled, and the machining directions are all in the same direction. The manufacturing process of the ratchet is relatively simple and there is no cumulative tolerance. The second body is provided with the second abutment, and the control rod is provided with the third abutment. The second abutment and the third abutment are mutually abutted, so that the control rod does not fall out of the second body. The magnetic attraction block is limited by the second body, and the magnetic attraction block only needs to be directly placed in the second groove. The control rod and the magnetic attraction block are limited by the second body and are assembled at the ratchet and the second body.

In order to enable the members of the Jun Bureau and those familiar with this technology to fully understand the effects of the present invention, the structure and composition of the present invention are explained below with diagrams and figure numbers. However, the following is only used to explain the implementation examples of the present invention and is not intended to limit the present invention in any form.
