Description

Ratchet wrench structure

The present invention relates to a ratchet wrench structure, in particular, a ratchet wrench structure has a first cover body and a first buckle ring at one end of the ratchet wrench structure, and the second cover body and the second buckle ring are disposed at the other end of the ratchet wheel. The first cover system abuts the first flange, the second cover system abuts the second flange, the ratchet, the first cover, the first buckle, the second cover and the second A buckle ring assembly is disposed on the body.

As previously known, the conventional ratchet wrench structure, as shown in Fig. 15, is a perspective exploded view of the conventional ratchet wrench structure, which includes a body 91 having a handle at one end. The first recess 911 is formed in a through hole shape, and the bottom of the first recess 911 is provided with a flange. The first recess 911 is adjacent to the handle. The second receiving slot 912 is in contact with the second receiving slot 912. The diameter of the second receiving slot 912 is smaller than the first receiving slot 911. The second receiving slot 912 is The center of the second receiving slot 912 is closed. The first receiving slot 911 is provided with a first retaining ring slot 914, and the second receiving slot 912 is provided. The bottom of the ratchet wheel 92 is provided with a ring. The ratchet wheel 92 is pivotally disposed in the first receiving groove 911. The ratchet wheel 92 is seated at the flange. Arranging the ratchet portion 921 of the tooth, The ratchet wheel 92 is provided with a sleeve portion 922 which is formed in a polygonal groove shape for the sleeve screwing member to be rotated. The ratchet wheel 92 is provided with a second buckle ring groove 923, and the second buckle ring groove is provided. The 923 is opposite to the first buckle groove 914; a tooth 93 is received on the inner side of the second groove 912, and the front side of the tooth 93 is provided with a plurality of teeth 931. The engaging teeth 931 are engaged with the ratchet portion 921; an elastic member 94 is disposed at one end of the elastic member 94, and the elastic member 94 is elastically attached to the bottom end of the elastic groove 32. The engaging teeth 931 are engaged with the ratchet portion 921; the retaining ring 96 is a C-shaped ring body and is slightly elastic, and the retaining ring 96 is configured. The first buckle groove 914 and the second buckle groove 923 are disposed in the first groove 911.

However, the missing structure of this conventional ratchet wrench is:

1. Referring to the sixteenth and seventeenth drawings, the volume of the tooth 93 is about six tenths of the volume of the second cavity 912, so that the tooth 93 and the second cavity 912 will form a space 95. Sometimes the ratchet 92 is limited to the screwing member, and the screwing member is limited to the screw hole, so that when the ratchet wheel 92 has rotational resistance, when the body 10 is rotated counterclockwise, That is, when the ratchet wrench structure is retracted, the ratchet 92 directly drives the tooth 93 to be displaced at the second pocket 912, and the ratchet 92 and the toothing 93 do not cause tooth retreat. It is commonly known as the idling phenomenon of a ratchet wrench. When the space 95 is larger, the idling angle is larger. Generally, the idling angle of the idling phenomenon is at least ten degrees.

2. The body 91 is provided with a second receiving slot 912, and the upper and lower sides of the second receiving slot 912 are closed. Therefore, the second pocket 912 of the body can only be formed by using a T-knife during processing. The use of the T-knife processing has the disadvantage of expensive processing, and the processing state of the T-shaped cutter is the T. After the cutter enters the first pocket 911, the cutter is displaced in the direction of the second pocket 912 to continue cutting. Finally, the cutter of the T-knife is slightly abutted against the inner circumference of the first pocket 911. The knives of the T-knife are formed by cutting the second pocket 912, such that the shank of the T-knife is limited to the inner circumferential surface of the first pocket 911, and the diameter of the shank of the T-knife cannot be too Large, the T-bar blade is easily broken and broken during processing.

3. The bottom of the first receiving groove 911 is provided with abutting edge, that is, the first receiving groove 911 has an inner diameter and a diameter, and the drill of the larger diameter drill bit needs to pay attention to the stroke of the drill bit when the first receiving groove 911 is drilled. The first container 911 having a large diameter is processed, and the drill of the larger diameter is required to pay attention to the stroke, which is relatively labor-intensive.

4. The magazine 914 is substantially opposite to the tooth 30, and the drill tool is drilled to avoid the inner circumferential surface of the first container 911, and the project of drilling the magazine 914 is relatively After the drilling, the magazine 914 naturally has a slope of three directions of XYZ with respect to the axis of the first pocket 911.

U.S. Patent No. 6,382,051, Taiwan Patent Publication No. 519,017, Application No. 91,207,257, which is incorporated herein by reference in the second portion of the U.S.A.A., the main body of the wrench body 50 reveals a chamber 52 which is closed on the upper and lower sides of the chamber 52. The structure of the sixteenth figure of the prior art has the missing points of the second point and the third point, and the slot 53 is provided at the side surface of the chamber 52, and the slot 53 should not be drilled using a drill bit. For the processing, the slot 53 has more cost if it is processed by other methods.

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

The upper and lower sides of the second tank are closed, so that the second tank can only be formed by using a T-knife during processing, and the use of the T-knife processing has the disadvantage of expensive processing. The first container, the second container and the first container are provided, the first container and the second container are penetrating, and the first container is open at one end. The processing of the first pocket, the second tank and the first magazine can save cost.

The present invention relates to a ratchet wrench structure, which comprises: a body, a ratchet, a tooth, an elastic component, a first cover, a first buckle, a second cover, and a second buckle.
