Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] attached figure 1 The wrench according to the present invention includes a wrench body 1; the wrench body 1 is a dismounting tool for disassembling round nuts; the wrench body 1 is a hollow tube, and the inner wall at one end rotates along it Four strip-shaped bosses with the same size as the four grooves on the round nut are evenly distributed in the center, and two parallel planes are symmetrically arranged on the outer peripheral surface of the other end, and there are also two parallel planes on the two parallel planes. A through hole perpendicular to it.

[0014] as attached figure 2 As shown, when used in a narrow space, the four strip-shaped bosses on the wrench body 1 can be inserted into the four grooves on the round nut 2 correspondingly, and the two parallel surfaces can be clamped and rotated with a tool. Realiz...

Abstract

The invention relates to a wrench. The wrench comprises a wrench body which is a hollow pipe; four stripe-shaped bosses, which are identical to four slots of a round nut in size, are uniformly and circularly formed on the inner wall of one end of the hollow pipe and around the rotating center of the hollow pipe; flat surfaces are formed on the external circumference of the other end of the hollow pipe and provided with perpendicular through holes. According to the wrench, the external circumference of one end of the wrench body is provided with the two flat surfaces in parallel and meanwhile the two parallel flat surfaces are provided with the perpendicular through holes, so that the wrench can achieve various application manners to adapt to various application conditions.

Description

technical field [0001] The invention relates to an improvement of a dismounting tool, in particular to a wrench adaptable to various working conditions. Background technique [0002] Common wrenches do not have multiple ways of use and cannot adapt to different working environments. During use, different wrenches need to be replaced according to various working conditions, which is a waste of time. Contents of the invention [0003] The purpose of the present invention is to provide a wrench adaptable to various working conditions in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a wrench, including a wrench body; the wrench body is a hollow tube, and the inner wall at one end is uniformly distributed with four circular nuts along the rotation center. The upper four strip-shaped bosses with the same groove size are provided with a plane on the outer peripheral ...
