Embodiment Construction

[0018] exist figure 1 , 2 and 3, a ratchet wrench includes a wrench head 2, a wrench body 7 with an extended handle, and a ratchet pawl mechanism. The head of the ratchet wrench is provided with a lateral rectangular opening. The outer cylindrical surface of the wrench head 2 is provided with a rectangular ratchet to cooperate with the inner cylindrical surface of the head of the wrench body 7 with an extended handle, and is fixed in the inner cylindrical surface of the head of the wrench body 7 through the axial limit of the cover plate 1. The wrench head 2 can rotate freely in the inner cylindrical surface of the head of the wrench body 7 . The cover plate 1 is a sheet-shaped ring structure, and is fixed on the wrench body 7 through the cover plate positioning pin 9 . The center of the wrench head 2 is provided with a regular hexagonal inner hole, which is used to cooperate with the hexagonal nut. The radius of the inner circle of the sheet-shaped annular structure cover p...

Abstract

The invention relates to a ratchet wrench. The ratchet wrench comprises a wrench body with an extending handle, and a wrench head, wherein the wrench head is assembled in the head portion of the wrench body in a rotary mode through a ratchet-and-pawl mechanism, a through hole is formed in the center of the wrench head, and is matched with a nut in shape, an outer sideward opening channel is formed in the head portion of the wrench body, and extends from the outer circumferential surface to the inner circumferential surface, and an inner sideward opening channel is formed in the wrench head, extends from the outer circumferential surface to the interior of the hexagonal-socket-shaped through hole, and corresponds to the outer sideward opening channel. Due to the fact that sideward openings are formed in the head portion of the ratchet wrench body, the ratchet wrench has the advantage that an open type wrench can be inserted from the side face, and further has the advantages that a ratchet wrench can work continuously, and the needed assembly space is small.

Description

technical field [0001] The invention relates to a work tool in the mechanical field, in particular to a ratchet wrench. Background technique [0002] In the hydraulic system, the hydraulic equipment is connected by hydraulic pipelines. With the miniaturization of products, the design of the hydraulic system needs to make full use of the space. The hydraulic system begins to use module integration to shorten the pipeline. The increasingly compact structure of the hydraulic system and the shortening of the pipeline lead to the reduction of the assembly space and increase the difficulty of assembly. In the hydraulic system, when connecting the pipe fittings or connecting the pipe fittings to the pipe fittings on the equipment, it is necessary to tighten the hexagonal connecting nut. To tighten the nut, use the existing adjustable wrench tool in the market. When assembling, the wrench needs to be turned 60° , with the increase of the nut specification, the space required for th...
