Description

Ratchet wrench structure

The present invention relates to a ratchet wrench structure, and more particularly to a ratchet wrench structure, wherein the first buckle fixes the first cover to the ratchet, so that the ratchet, the tooth and the elastic component are accommodated thereto. In the body, the other side is closed by the second cover, the third cover and the second buckle.

As previously known to us, the conventional ratchet wrench structure, such as U.S. Patent No. 6,862,955, Taiwan Patent Application No. 092222517, patent name: improvement of a ratchet wrench, is based on an improvement of a ratchet wrench, including: a wrench The main body is provided with a first accommodating groove and a second accommodating groove; the positioning member has a positioning portion for arranging the spring, and is placed on the first accommodating groove and the second accommodating groove of the wrench body;掣 block: the two sides are provided with a card tooth and a top surface, and are placed in the second accommodating groove of the wrench body, and the top surface is placed on the spring; the ratchet: has a working end and is installed at the first In the accommodating groove, the card teeth of the card 啮合 block are engaged, and then a limit member is used for assembly and positioning to prevent the wrench body from coming off.

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

1. The opening of the first receiving groove is a single inner diameter, and the positioning member is matched with the first The shape of the accommodating groove and the second accommodating groove is a two-diameter plate shape, and the positioning member is placed in an oblique path plus a curved line path plus a horizontal path state. In the accommodating groove and the second accommodating groove, the action of inserting the positioning member is troublesome.

2. In addition, as shown in the third and fourth figures of the bulletin, the wrench system is provided with a second accommodating groove, and the upper and lower sides of the second accommodating groove are closed, so the second accommodating groove In the processing, it can only be formed by using a T-shaped knife. The use of the T-shaped knife processing has the disadvantage of expensive processing. The processing state of the T-shaped knife is that the T-shaped knife enters the first receiving groove and is tied to The second accommodating groove is displaced in the direction of continuous cutting, and finally the arbor of the T-shaped blade is slightly abutted against the inner circumferential surface of the first accommodating groove, and the knives of the T-shaped blade are formed by cutting the second The shank of the T-shaped blade is limited to the inner circumferential surface of the first accommodating groove, and the diameter of the arbor of the T-shaped blade cannot be too large, and the shank of the T-shaped blade is processed. At that time, it is easy to be broken by force, and the loss rate of the T-knife is quite high.

3. The bottom of the first accommodating groove is provided with abutting edge, that is, the first accommodating groove 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 drilling the first accommodating groove. The first accommodating groove 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 inner circumferential surface of the first accommodating groove of the wrench body is machined with a ring groove. Generally, if the inner diameter of the first accommodating groove is 15 MM or more, turning the ring groove system does not have much problem. If the inner diameter of the first accommodating groove is 12 mm or less, turning the ring groove is labor-intensive.

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

In the conventional ratchet wrench structure, the opening of the first accommodating groove is a single inner diameter, and the positioning member is configured to match the first accommodating groove and the second accommodating groove to have a two-diameter plate shape. The positioning member is placed in the first receiving groove and the second receiving groove by an oblique path plus a curved line path plus a horizontal path state, and the action of placing the positioning member is troublesome. The first buckle in the ratchet wrench structure of the present invention fixes the first cover to the ratchet, so that the ratchet, the tooth and the elastic component are received into the body, and the second cover is passed through the second cover The third cover and the second buckle are then closed on the other side to complete the assembly.
