Ratchet wrench structure

The present invention is related to a ratchet wrench structure, and particularly the system of the ratchet wrench structure is provided with the first pocket, the second pocket and the third pocket, the first pocket is penetrating, the first The second tank and the third tank are open at one end.

As previously known by us, the conventional ratchet wrench structure, such as US Patent No.: US6282992B1, Taiwan Patent Application No.: 089202280, Bulletin No.: 408653, Patent Name: Throat Tool (1), its patent structure is: The wrench body 10 has a head portion 11 at one end and a handle portion 12 at the other end. A first receiving portion 13 is formed in the head portion 11, and a third receiving portion is disposed in the handle portion. A second accommodating portion 14 is disposed between the first and third accommodating portions 13 and 15; a reversing switch 50 is inserted into the third accommodating portion 15 of the wrench body 10 and rotatable relative to the shank portion 12 Positioning; a top cymbal device 60 is inserted into the reversing switch 50 and can be rotated and positioned with the reversing switch 50; a latching member 40 is provided with a tooth portion 41 on one side thereof, which is inserted into the wrench body 10 The second accommodating portion 14 is coupled to one side of the non-toothed portion 41 and can be moved by the top cymbal device 60 to the second accommodating portion 14; a ratchet member 70 is attached In the shape of a cylinder, the peripheral ring is provided with a tooth portion 71 which is fixed to the first receiving portion 13 of the head portion 11 and can be phased. 11 as a rotary head, wherein the teeth on the toothed portion 40 and the engaging member 71 line 41 was bonded state.

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

1. The second housing portion 14 is disposed between the first receiving portion 13 and the third receiving portion 15 of the wrench body 10, as shown in the first figure of the U.S.A. The upper and lower sides of the 14 are closed, so that the second receiving portion 14 can only be formed by using a T-shaped knife during processing, and the T-shaped cutting process has the disadvantage of expensive processing, and the processing of the T-shaped knife is processed. The state is that the T-shaped knife enters the first accommodating portion 13 and is displaced in the direction of the second accommodating portion 14 to continue cutting. Finally, the arbor of the T-shaped blade is slightly abutted against the first accommodating portion. The inner surface of the inner surface of the first accommodating portion 11 is deformed by the knives of the T-shaped knives, and the knives of the T-shaped knives are limited to the inner circumferential surface of the first accommodating portion 11 The diameter of the cutter bar of the type cutter cannot be too large, and the cutter bar of the T-shaped cutter is easily broken by force during processing.

2. In addition, as shown in the second figure of the U.S. Gazette, the first accommodating portion 13 has an inner diameter and a diameter, and the drill of the larger diameter drills the first accommodating portion 13 to pay attention to the stroke of the drill bit. The first accommodating portion 13 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.
