Description

Multi-purpose electric wrench extension sleeve

Technical Field

The utility model relates to the technical field of hardware tools, in particular to a multipurpose electric wrench lengthening sleeve.

Background

The electric wrench is an electric tool for screwing and unscrewing the bolt and the nut, is a tool for screwing the high-strength bolt, and is used for initial screwing, final screwing and initial screwing of the torsional shear type high-strength bolt in the construction of mounting the large hexagon-head high-strength bolt on a steel structure bridge, a factory building, a chemical industry and power generation equipment, and occasions with strict requirements on the torque or the axial force of a bolt fastener. The electric wrench is generally used with a wrench socket, and in some environments, the wrench lengthening socket needs to be matched.

Electric spanner extension sleeve includes the telescopic link, the nut sleeve of telescopic link's one end for being equipped with interior hexagonal hole, the other end is for being used for assembling the connector on electric spanner, the center of connector is equipped with the assembly spliced eye. The utility model CN212497491U is filed by the applicant in 6.7.2020, and issued by 9.2.2021. The utility model discloses an electric wrench lengthening sleeve, the sleeve rod, the nut sleeve and the connector of the electric wrench lengthening sleeve are integrated into a whole formed by a die at one time, thereby not only saving the welding cost and shortening the production period, but also avoiding the phenomena of fracture and drop in the use process and having long service life; meanwhile, the concentricity is high, the head is not thrown, and the electric wrench can be effectively protected; the nut containing cavity is arranged in the nut sleeve, 3-4 nuts can be disassembled and then taken away together, so that the time is saved, and the efficiency is improved. However, the inner hexagonal hole of the nut socket of the electric wrench lengthening socket has a single aperture, and can only be used for dismounting one type of nut, so that the application range is small and needs to be improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a lengthening sleeve of a multipurpose electric wrench, and solves the technical problems.

In order to solve the problems, the technical scheme adopted by the utility model is as follows:

a multi-purpose electric wrench lengthening sleeve comprises a sleeve rod, wherein one end of the sleeve rod is a nut sleeve provided with a first hexagon socket, and a nut accommodating cavity for accommodating a plurality of nuts is arranged in the nut sleeve; the other end of the sleeve rod is a connector which is used for being assembled on an electric wrench, and an assembling insertion hole is formed in the center of the connector; the method is characterized in that: a nut sleeve ring is connected between the sleeve rod and the nut sleeve, and is provided with a second hexagon socket; the aperture of the second hexagon socket is smaller than that of the first hexagon socket.

Preferably, two U-shaped openings are symmetrically formed in the side wall of the top end of the nut sleeve.

Preferably, an annular groove is formed between the connector and the sleeve rod, two through holes are formed in the annular groove, and the centers of the two through holes are located on the same straight line.

Preferably, the assembling insertion holes are rectangular holes or square holes.

Has the advantages that: compared with the prior art, the nut sleeve ring is additionally arranged between the sleeve rod and the nut sleeve, and the nut sleeve ring is provided with the second inner hexagonal hole with the hole diameter smaller than that of the first inner hexagonal hole, so that the original performance of the nut sleeve is maintained, the nut sleeve ring can be matched with the nuts of two different models to be disassembled and assembled, the application range is expanded, and the practicability is improved.

Detailed Description

The utility model is further described with reference to the following figures and detailed description.

Example 1:

as shown in fig. 1 and 2, the extension socket for a multi-purpose electric wrench according to the present embodiment includes a socket rod 2, a nut socket 4 having a first hexagonal socket 6 is disposed at one end of the socket rod 2, and a nut receiving cavity for receiving a plurality of nuts is disposed in the nut socket 4. A nut ring 3 is connected between the sleeve rod 2 and the nut sleeve 4, the nut ring 3 is provided with a second hexagon socket 9, and the aperture of the second hexagon socket 9 is smaller than that of the first hexagon socket 6.

The other end of the sleeve rod 2 is a connector used for being assembled on the electric wrench, an assembling inserting hole 8 is formed in the center of the connector, and the assembling inserting hole 8 is a rectangular hole or a square hole. An annular groove 1 is arranged between the connector and the sleeve rod 2, two through holes 7 are arranged in the annular groove 1, and the circle centers of the two through holes 7 are on the same straight line.

Example 2:

referring to fig. 3 and 4, compared with embodiment 1, the extension socket of the multi-purpose electric wrench of the present embodiment is different in that: two U-shaped openings 5 are symmetrically arranged on the side wall of the top end of the nut sleeve 4.

Compared with the utility model CN212497491U, the multipurpose electric wrench lengthening sleeve is additionally provided with the nut ring 3 between the sleeve rod 2 and the nut sleeve 4, and the nut ring 3 is provided with the second inner hexagonal hole 9 with the aperture smaller than that of the first inner hexagonal hole 6, so that the multipurpose electric wrench lengthening sleeve not only keeps the original performance, but also can be matched with the dismounting and mounting of two nuts with different models, thereby expanding the application range and improving the practicability.

As an extension of the present invention, a plurality of nut rings 3 may be provided between the sleeve rod 2 and the nut sleeve 4, and the bore diameters of the hexagonal socket holes in the respective nut rings 3 decrease from top to bottom, so that more types of nuts can be matched.
