The guiding piece 77 is sleeved with a supporting spring 78, so that the positioning piece 75 can be stably supported on the ratchet block 65; thereby forming a dial structure with a smooth and well-positioned ratchet wrench.

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

1. Please refer to the fifth and sixth figures of the bulletin. The total length of the positioning piece 75 is usually smaller than the outer diameter of the dial 70, and many users will rotate the tool head by pressing the dial 70. 60 to test the topping sound of the ratchet block 65, the positioning piece 75 may be pressed by the ratchet block 65 against the top stay spring 78, and the positioning piece 75 will completely fall into the dial block 70, such as 19 is a cross-sectional view of a conventional ratchet wrench, the positioning piece 75 does not protrude to the spine pocket 53 so that the positioning piece 75 follows the dial 70 to the dial block. The cavity 54 can be rotated by three hundred and sixty degrees, and the rotation of the positioning piece 75 will be hidden inside the dialing pocket 54, that is, the excessive operation is lost.

2. In the state in which the nineteenth figure is excessively rotated, if the user rotates the dial 70 clockwise, the dial 70 and the positioning piece 75 can be returned, and the ratchet wrench structure can still be used. However, some users will continue to rotate the toggle 70 counterclockwise. When turning to the angle of the twentieth diagram, the twentieth diagram is a cross-sectional view of the conventional ratchet wrench, and the spine 65 and the spine pocket 53 are When there is a gap, the positioning piece 75 is elastically attracted to the gap by the elastic force of the top spring 78, and the ratchet block 65 and the positioning piece 75 are simultaneously accommodated in the spine pocket 53, and the ratchet wrench structure can no longer be continue to use.

Another conventional ratchet wrench structure, which is the patent application filed by the applicant, Taiwan Patent Application No.: 101102061, certificate number I409144, patent name: ratchet wrench structure, please be accompanied by the first figure of the bulletin, The patent case has the disadvantage of avoiding over-switching, but the steering member 41 needs to be fastened by the first buckle 44, so that the body 10 is to process the first buckle groove 131, and the diameter of the third cavity 13 is generally It may not be too large. If the body 10 is two-pointed, the diameter of the third pocket 13 may be 6 mm, and the first pocket is processed in the third pocket 13 of the diameter of 6 mm. The buckle groove 131 is relatively labor-intensive and processed, and the cutter system of the first buckle groove 131 is very small and causes another defect.
