For achieving the above object, the technical scheme adopted by the present utility model is:

A working tool on a V-series connection fitting, comprising a universal socket and a socket wrench, the socket wrench comprises a cylindrical part and a conical part connected in sequence, the universal socket is fixed on the free end of the cylindrical part of the socket wrench, The cylindrical part of the socket wrench is provided with at least two positioning cards along the circumferential direction. When the positioning cards are in a natural state, part of the positioning card extends out of the socket wrench, and enters the socket wrench after being subjected to radial pressure, and the positioning card extends out of the socket wrench in the natural state. It forms a triangle with the socket wrench, and the angle between the side close to the universal socket and the socket wrench is not more than 90°, and the angle between the other side facing the conical part of the socket wrench and the socket wrench is greater than 90° °.

As an improvement of the utility model, the universal sleeve is a GATOR GRIP universal sleeve. This new socket can fit any type of screw.

Compared with the prior art, the beneficial effects of the present utility model are:

1. The conical part set at one end of the socket wrench is easy to insert into the connecting hole of the fitting, and flexible installation and disassembly are realized through the elastic positioning card, which is convenient for the operator to use this tool as a temporary foot nail to enter and exit the insulator string fitting.

2. The universal socket set at the other end of the socket wrench can be used to fasten the bolts of the pressure equalizing ring after reaching the working position, which solves the problem that one set of tools can complete the relevant work, and greatly reduces the problems caused by too many tools. Risk of falling objects.

Detailed ways

In order to make the above objects, features and advantages of the present utility model more clearly understood, the present utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , a working tool on a V-series connection hardware includes a universal socket 1 and a socket wrench 2 . The socket wrench 2 includes a cylindrical portion 21 and a conical portion 22 which are connected in sequence. One end of the cylindrical portion 21 is provided with a mounting hole, the universal sleeve 1 is sleeved in the mounting hole and fixed by welding, and the other end of the cylindrical portion 21 is smoothly connected with the conical portion 22 .

The universal socket 1 adopts the GATOR GRIP universal socket, which uses 54 retractable high-hardness steel columns inside. When it is placed on the screw, the steel column inside it can tighten the screw. Hold, no matter what shape the screw is, it can be firmly locked. In this way, when the operator arrives at the working position, it can be used to tighten the bolts of various specifications of the pressure equalizing ring, and a set of tools can be used to complete the relevant work. The problem of operation greatly reduces the risk of falling objects caused by too many tools.

The other end of the socket wrench 2 is provided with a conical portion 22, which not only facilitates the alignment of the upper and lower mounting holes during the installation process of the hardware clip, but also allows the working tool to be inserted into the connecting hole of the hardware to connect it as a temporary foot nail. Enter the ladder and other tools to facilitate the operator to enter and exit the insulator string fittings.

When the working tool is used as a temporary foot nail, it is not prevented from coming out of the connection hole and needs to be positioned. The present application adopts the design of the retractable buckle of the umbrella. In the natural state, the positioning clip 3 partially protrudes from the outer wall of the cylindrical portion 22. After receiving radial pressure, it enters into the cylindrical portion 22. The portion of the positioning clip 3 protruding from the cylindrical portion 22 in the natural state and the socket wrench 2 A triangle is formed, and the angle between the side close to the universal socket 1 and the socket wrench 2 is not greater than 90°, and the angle between the other side facing the conical part 22 and the socket wrench is greater than 90°. In this way, when the socket wrench 2 is inserted into the connecting hole through the conical portion 22, the positioning card 3 retracts, so that the cylindrical portion 22 passes through the connecting hole, and is finally caught by the universal sleeve 1, which becomes a temporary foot nail, and the positioning card 3 After passing through the connecting hole, the socket wrench 2 can be prevented from being pulled out, and the reliable positioning of the socket wrench 2 can be ensured. When the socket wrench 2 is to be pulled out, it is only necessary to press and retract the positioning card 3 by hand to retract it into the inside of the socket wrench 2 .

Fig. 2 shows a connection method of the positioning card 3. A section of the cylindrical portion 22 is hollow, a pin shaft 4 is arranged in the hollow portion near the upper end of the universal sleeve 1, and the upper end of the positioning card 3 is rotatably connected to the pin through elastic components such as a torsion spring. On the shaft 4, the lower end of the hollow portion is provided with two rectangular through grooves for the lower end of the positioning card 3 to pass through, so that the extension and retraction of the positioning card 3 can be realized. Of course, the connection method of the positioning card 3 is not limited to this. One end of the positioning card 3 is elastically hinged inside the cylindrical portion 22, and the other end is partially extended.

It can be seen that, in the working tool of the present application, the conical portion 22 provided at one end of the socket wrench 2 can facilitate the alignment of the upper and lower installation holes during the installation process of the fitting card plate, and the setting of the positioning card 3 is convenient for the socket wrench 2 For the connection with the fittings, use it as a temporary pin to get in and out of the insulator string fittings. The universal socket 1 set at the other end of the socket wrench 2 can be used to fasten the bolts of the pressure equalizing ring after reaching the working position, which solves the problem that one set of tools can complete the related work, and greatly reduces the trouble caused by too many tools. Risk of falling objects.

The above detailed description is a specific description for the feasible embodiments of the present invention, and the embodiments are not intended to limit the scope of the patent of the present invention. Any equivalent implementation or modification that does not depart from the present invention should be included in this case. within the scope of the patent.
