Problems solved by technology

[0011] Due to the processing error, the two pawls 94 are prone to jamming, and finally cause the lack of movement. If the problem is to be improved by improving the processing accuracy, the precision processing technology will lead to huge costs and costs. , and cannot be widely accepted by the market. In addition, problems such as processing errors or positioning position errors of the control parts can easily lead to the above-mentioned stuck problems. Therefore, the applicant proposes this patent application to solve the aforementioned problems question

Embodiment Construction

[0050] refer to Figure 1 to Figure 3 , is the first embodiment of the anti-seize ratchet wrench of the present invention. The ratchet wrench 10 of the present invention includes a body 20, a driving member 30, a ratchet device 40, a reversing switch 50 and a limiter 60, the limiter 60 prevents the ratchet device 40 from being stuck on the drive member Between 30 and the body 20, the problem of the ratcheting device 40 being stuck can be effectively avoided; wherein:

[0051] The body 20 includes a head 21 . The head 21 of the body 20 has a rotation axis CL. When the user operates the body 20 , the body 20 can be rotated around the rotation axis CL of the head 21 .

[0052] The head 21 includes a first surface 211 and a second surface 212 . The first surface 211 and the second surface 212 are parallel to each other and spaced apart along the rotation axis CL.

[0053] The head 21 is provided with a circular first accommodation space 22 extending along the rotation axis CL a...

Abstract

The invention discloses an anti-block ratchet wrench which comprises a wrench body. The wrench body is provided with a first containing space and a second containing space, a drive unit is disposed in the first containing space in a rotary mode, a ratchet device is disposed in the second containing space of the wrench body, the ratchet device comprises a first ratchet block, a second ratchet block and an elastic unit, a reversing switch is pivoted to a control groove and is capable of controlling engagement of the ratchet device and the drive unit, a locating unit is connected to the first ratchet block and the second ratchet block of the ratchet device, the locating unit enables the first ratchet block and the second ratchet block of the ratchet device to keep a distance as large as one restrained tooth number from the nearest two tooth parts of each, and the distance of the restrained tooth number is smaller than the distance of a blocking tooth number. Therefore, the ratchet device is prevented from being blocked.

Description

technical field [0001] The invention mainly discloses a ratchet wrench, especially a ratchet wrench capable of preventing a ratchet device from being stuck. Background technique [0002] Please refer to U.S. Patent No. 6,981,434 "Reinforcement structure for wrench head", which is a ratchet wrench (wrench). The wrench has a through hole for accommodating an engaging wheel. A recess and a space can accommodate two pawls, and the two pawls can be driven by a control member. [0003] As in Patent No. 6,981,434 image 3 , Image 6 and Figure 7 As shown, the control member can respectively switch the positions of the two pawls, so that one of the two pawls can be engaged with the combination wheel, so that the combination wheel can produce a function of unidirectional rotation relative to the wrench. [0004] This wrench with two pawls presents machining difficulties, see Figure 10 , which is a simplified diagram based on the 6,981,434 patent, Figure 10 Shown in the figure...
