Problems solved by technology

[0002] During the production and construction of existing wrenches, most of them are hexagonal wrenches. This kind of wrench has the characteristics of cumbersome operation, labor-intensive and time-consuming, and serious wear and tear, and its service life is extremely short, which brings great inconvenience to our production and life. For some rusty fixing screws, the strength of a construction worker is limited, and the process of exerting force is limited, which delays the work efficiency. In the setting of the handle of the wrench, many wrenches are rigid and inflexible, and the torque cannot be changed, resulting in excessive force. use cannot be reasonably allocated

Embodiment Construction

[0010] Such as figure 1 As shown, a new type of wrench includes a wrench body, the wrench head is composed of a spike 1 and a circular fork 2, a wrench handle is arranged on the lower part of the wrench body, and an afterburner rod 4 is left on the wrench handle, and the afterburner There is a round hole on the rod 4, and the booster rod 4 and the wrench handle are connected by the bolt 3.

[0011] The spikes 1 are conical and irregularly arranged in the mouth of the circular fork 2 .

[0012] During use, the handle of the wrench is lengthened, and the torque is lengthened, which is convenient for the operator to use force to remove the rusty fixing screw, and the afterburner rod 4 can be used or not according to the needs, which does not affect the use of the wrench alone. The round fork 2 and the pointed For the matching of thorn 1, you only need to align with the round nut and twist it.

[0013] An embodiment of the present invention has been described in detail above, bu...

Abstract

The invention relates to a novel wrench. The novel wrench comprises a wrench body. The novel wrench is characterized in that a wrench head consists of a spine and a circular fork; a wrench handle is arranged on the lower portion of the wrench body; a stress application rod is reserved on the wrench handle; a circular hole is formed in the stress application rod; and the stress application rod is connected with the wrench handle through a bolt. The novel wrench is convenient to operate and is simple; the labor is saved; the work efficiency is improved; and moreover, the novel wrench is low in cost and is suitable to be produced in batches.

Description

technical field [0001] The invention relates to a new type of wrench. Background technique [0002] In the production and construction process of existing wrenches, most of them are hexagonal wrenches. This kind of wrench has the characteristics of cumbersome operation, labor-intensive and time-consuming, and serious wear and tear, and its service life is extremely short, which brings great inconvenience to our production and life. For some rusty fixing screws, the strength of a construction worker is limited, and the process of exerting force is limited, which delays the work efficiency. In the setting of the handle of the wrench, many wrenches are rigid and inflexible, and the torque cannot be changed, resulting in excessive force. Use cannot be allocated reasonably. Contents of the invention [0003] The purpose of the present invention is to provide a novel wrench which is convenient to operate, labor-saving and simple, improves work efficiency, is low in cost, and is...
