Description

Simple wrench

Technical Field

The utility model relates to a hardware tool especially relates to a simple and easy type spanner to adapt to the application in special place.

Background

The invention discloses a wrench disclosed in Chinese invention patent application (publication number: CN 103639972A). A wrench comprises a handheld part and a fork opening connected to one end of the handheld part, wherein the fork opening is used for forking screws, an illuminating device is further arranged on the handheld part and comprises a bulb, a battery and a switch, the bulb is arranged on the handheld part and close to the fork opening, a lamp holder of the bulb is opposite to the fork opening, a groove is formed in the handheld part, the battery is placed in the groove, and the bulb is electrically connected with the battery and the switch. The wrench provided by the invention is provided with the lighting device, so that the function of needing to operate the wrench under the condition of a dark surrounding environment or poor light can be realized, and the wrench can be used as a flashlight.

The wrench has no difference in function with a common wrench, but the wrench is obviously inconvenient to use in some special application places. For example, in the tightening operation of a lock nut of a faucet shaft of an electric vehicle, particularly in the maintenance of a structure on the faucet shaft of the electric vehicle, because the electric vehicle is provided with the faucet shaft rear baffle, when an ordinary wrench operates the lock nut, the rear baffle can block the action of the wrench, so that the operation of the lock nut on the faucet shaft can be influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem who needs the solution: provided is a simple wrench which is convenient for one-side operation and can be well adapted to work in some specific occasions.

For solving the technical problem, the technical scheme of the utility model: the simple wrench comprises a body and is characterized in that a fork opening is formed in the inner side edge of the body, two parallel side faces are arranged in the fork opening and are arranged at intervals, and a plurality of connecting structures used for being connected with a rod body are arranged at the outer side edge of the body.

The prong is adapted to mate with a prism, typically a hexagonal prism, such as a hexagonal nut or screw, and has a pair of spaced parallel sides that engage a pair of parallel surfaces on the mating object. The rod body is connected with the connecting structure, and the body drives the nut or the screw to rotate by pulling the rod body, so that the screwing or loosening of the thread is realized.

Further, the side faces are proximate the open ends of the jaws. This makes the body easy to cooperate with a nut or a screw, facilitating the operation.

Furthermore, a plurality of notches are arranged on the outer side edge of the body, and the connecting structure is formed in the notches. Through being provided with the breach, and the hookup between the body of rod and the body of being convenient for, and the breach is a plurality of, and through the hookup between the body of rod and the breach of difference, and conveniently pulls the body.

Furthermore, a plug is arranged on the bottom surface of the notch, and a gap is formed between the plug and the notch. The end part of the hollow rod body can be sleeved on the plug, so that the rod body is connected with the connecting structure, and the connecting stability between the rod body and the body is good.

Furthermore, a plurality of jacks are arranged on the outer side edge of the body, and the jacks form the connecting structure. The rod body is inserted in the jack, so that the connection between the rod body and the body is realized, and the connection firmness between the rod body and the body is good.

Therefore, the utility model has the advantages that: the simple wrench has the advantages that the simple wrench is structurally a body which can be a sheet-shaped body or a block-shaped body, the body is compact in structure, and accordingly cooperation between the body and an expected operation part in a narrow space is facilitated. Set up a plurality of draw bail on the outside edge of body, promote the body through the body of rod and draw bail's cooperation and rotate from the outside of body, made things convenient for the operation to the body for this simple and easy spanner can fine adaptation work demand.

Detailed Description

In the figure, the simple wrench is used for driving objects to rotate so as to realize the screwing or loosening of threads between the objects. The main structure of the simple wrench is a body 1, the body 1 is a plate-shaped body and has a certain thickness, and the shape of the body 1 is similar to a semicircle. A fork 2 is arranged at the diameter part of the body 1, namely the inner side edge of the body 1, and the fork 2 is used for matching with a nut or a screw rod of a hexagonal prism. The fork 2 has two parallel side surfaces 21, the two side surfaces 21 are arranged at intervals and are positioned at the opening end of the fork 2, and the two side surfaces 21 are used for being in cross joint with a pair of parallel surfaces on the nut or the screw rod so as to realize the relative circumferential fixation of the body 1 and the screw rod or the nut.

The outer circumferential surface of the body 1 is also provided with a plurality of connecting structures at the outer edge of the body 1, the connecting structures are used for connecting with the rod body, and the rod body is used for pushing the body 1 to enable the body 1 to drive the nut or the screw rod to rotate.

In one embodiment, a plurality of notches 3 are formed on the outer edge of the body 1, the notches 3 are uniformly distributed on the outer edge of the body 1, and the connecting structure is formed in the notches 3. The method comprises the following steps: the bottom surface of the gap 3 is provided with a plug 4, a gap is arranged between the plug 4 and the gap 3, the plug 4 is generally in threaded connection with the body 1, and the plug 4 and the body 1 can also be integrally formed. When the rod body is connected with the connecting structure, the end part of the hollow rod body is positioned in the gap 3 and is sleeved on the plug 4.

In another embodiment, a plurality of insertion holes 5 are formed on the outer edge of the body 1, the insertion holes 5 are uniformly distributed on the outer edge of the body 1, and the insertion holes 5 form the connecting structure.
