Description

Lengthened socket wrench

Technical Field

The invention relates to the technical field of machining tools, in particular to a lengthened socket wrench.

Background

In the existing electric equipment maintenance process, a wrench is often needed to screw or unscrew the bolt. The conventional spanner is inside because of the limited phenomenon such as not opening of executing of position, consequently often enlarges the scope of overhaul, dismantles peripheral equipment and the part that hinders, just can dismantle the bolt, greatly increased personnel's work load and maintenance cost.

Disclosure of Invention

The invention aims to provide a lengthened socket wrench, which solves the technical problems that the use of a conventional wrench is limited by environment and the torque is too small when a single person uses the wrench. The technical effects that can be produced by the preferred technical scheme in the technical schemes provided by the invention are described in detail in the following.

In order to achieve the purpose, the invention adopts the following technical scheme:

an extension socket wrench; the wrench comprises a wrench sleeve head and a hand wheel type handle, wherein at least one extension bar which can be connected with each other is connected between the wrench sleeve head and the hand wheel type handle.

Through setting up the connecting rod between spanner sleeve head and the hand wheel formula handle into extension bar that can interconnect, can adjust the quantity of extension bar between spanner sleeve head and the hand wheel formula handle, increase the holistic length of spanner to adapt to the condition that some bolt positions are narrow and small, the space is not enough to be difficult to the dismantlement.

Furthermore, a first connecting groove and a second connecting lug boss are respectively arranged at two ends of the extension bar.

The first connecting groove and the second connecting boss are respectively arranged at two ends of the extension bar, so that the extension bar can be connected with each other, and the first connecting groove and the second connecting boss can also be used for connecting a sleeve head of a wrench and a hand wheel type handle.

Furthermore, one end of the wrench sleeve head is provided with a first connecting boss connected with the first connecting groove.

A first connecting boss arranged at one end of the wrench sleeve head is connected with a first connecting groove of the extension rod, and a spring is further arranged in the first connecting boss.

And furthermore, a second connecting groove connected with a second connecting boss is formed at the lower end of the hand wheel type handle.

Preferably, a plurality of extension bars between the wrench socket and the hand wheel type handle are connected with each other through a first connecting groove and a first connecting lug boss to increase the distance between the wrench socket head and the hand wheel type handle.

Preferably, the hand wheel type handle is additionally provided with a knocking rod on the excircle of the handle round wheel; the people can use the tup to strike the pole, increases the moment to the spanner.

Preferably, springs are arranged in the first connecting groove and the second connecting boss.

Based on the technical scheme, the following technical effects can be generated:

the lengthened socket wrench provided by the invention can be used for treating bolts which are not suitable for a conventional wrench at a narrow position. The lengthened socket wrench provided by the invention has the advantages that the traditional wrench plate is changed into the lengthened rod which can be lengthened infinitely, and the hand wheel type handle is arranged, so that the technical problems that the conventional wrench is limited by environment in use and the torque is too small when a single person uses the wrench are solved.

The lengthened socket wrench has the following advantages:

1. the extension bar can be infinitely lengthened and is suitable for processing various bolts positioned at narrow positions.

2. The wrench rod is lengthened, so that the wrench is prevented from deviating when the wrench is loosened and loosened due to overlong length, the handle is arranged in a round wheel mode, operators can apply force uniformly and symmetrically, and the wrench can be operated by two persons at the same time.

3. To the bolt that is difficult to dismantle, this product has extended on the basis of hand wheel, has increased the pole of strikeing to the round wheel excircle, and personnel can strike with the tup, have increased the moment to the spanner.
