Embodiment Construction

[0064] Regarding the technology, means and effects of the present invention, a preferred embodiment is given in conjunction with the drawings in detail as follows, refer to Figure 2 to Figure 4 ,as well as Figure 7 to Figure 12 , The open-end wrench 10 of the present invention includes a body 20, a slider 30 and an elastic device 40; wherein the body 20 has a gripping portion 21 and a jaw 22 provided at the front end of the gripping portion 21. The jaw 22 can be connected to the work piece 90, such as the hexagonal head of a bolt. When the work piece 90 is the hexagonal head of the bolt, the six force-bearing surfaces are arranged in a counterclockwise ring at the six o'clock direction of the hexagonal head. A positive force receiving surface 91A to a sixth positive force receiving surface 96A, similarly, also has a first reverse force receiving surface 91B to a sixth reverse force receiving surface 96B. The user can hold the grip 21 and pull the main body 20 so that the jaw 2...

Abstract

The invention discloses an open end wrench capable of being wrenched to and fro. The open end wrench comprises a body which is provided with a grip jaw; a sliding chute is formed in the grip jaw; a chute body of the sliding chute can be processed at one time; a sliding block can slide along an arc in the sliding chute and is provided with a guide slot through which a guide column can pass to ensure a structure is reinforced and does not fall off easily; two sides of a first wrenching plane of the sliding block are provided with a first expanding surface respectively; a first jaw and a second jaw of the clamping jaw, the first wrenching plane of the sliding block and an inner circle diameter formed between two expansion surfaces can rotate relative to an axis position of a working substance and do not generate clamping interference; and the areas of the expansion surfaces of the two sides of the sliding block are expanded outward from the first wrenching plane to two side walls of a first support wall and a second support wall of the body, so the contact area of the first wrenching surface and a fourth forward-direction stress surface of the contacted working substance is increased.

Description

Technical field [0001] The invention relates to an open-end wrench, especially an open-end wrench that can be turned on a work object and can be moved back and forth relative to the axis position of the work object. Background technique [0002] Among the existing structural designs in the technical field of the present invention, there was previously a structural design of US Patent No. 1,320,668. The wrench discloses a stationary jaw and a movable jaw. The movable jaw passes through a spring ) Can slide back and forth on the guide. When the user wants to turn the nut, turning the wrench allows the fixed claw and the movable claw to drive the nut to rotate. When the user wants to move the wrench to the next turning position, turning the wrench in the opposite direction allows the movable pawl to retreat and compress the spring without driving the nut to rotate. Repeated operation of the aforementioned actions can achieve the effect of locking or loosening the nut. However, si...
