Description

Technical Field

[0001] The utility model relates to the application field of an electric wrench socket, in particular to an electric wrench socket tool with a larger specification. Background Art

[0002] Electric wrench is an electric tool for tightening and loosening bolts and nuts. It is a tool for tightening high-strength bolts. It is used for the initial tightening and final tightening of large hexagonal high-strength bolts installed in steel structure bridges, factory buildings, chemical industry, power generation equipment, and the initial tightening of torsion shear type high-strength bolts, as well as occasions with strict requirements on the torque or axial force of bolt fasteners.

[0003] In the prior art, when an electric wrench and a socket head are used to tighten larger hexagonal bolts (M36 and above), when the electric wrench is lifted, the socket head is easily separated from the driving shaft of the electric wrench due to various factors such as gravity, which is a technical defect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to solve the problem that a socket head with a larger specification is easy to fall off from an electric wrench.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a larger-sized electric wrench socket tool, including an electric wrench and a socket head, the socket head is movably sleeved on the output shaft of the electric wrench, and also includes a mounting sleeve, a spring lug and a pulling spring, the mounting sleeve is installed on the output shaft of the electric wrench, the spring lug is arranged on the socket head, and the pulling spring is suspended between the mounting sleeve and the spring lug.

[0006] Furthermore, the mounting sleeve is provided with a groove, and the tension spring suspension is located in the groove.

[0007] Furthermore, the grooves are provided in two groups, the lifting springs are provided in two groups, and the spring ears are provided in two groups.

[0008] Preferably, the mounting sleeve is a set of components, consisting of a symmetrical mounting frame, mounting bolts and nuts.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows: an external mounting sleeve, a spring lug and a lifting spring are provided, an additional connection is added to the electric wrench and the socket head, the cost is not increased, the structure is simple, the existing problems can be solved, and disassembly and assembly are also very convenient.

[0014] like Figure 1~Figure 3 As shown, the utility model is a larger-specification electric wrench socket tool, comprising an electric wrench 1 and a socket head 2. The socket head 2 is movably sleeved on the output shaft of the electric wrench 1. Products of appropriate specifications can be selected according to actual needs. It also includes a mounting sleeve 3, a spring lug 4 and a pulling spring 5. The mounting sleeve 3 is mounted on the output shaft of the electric wrench 1, the spring lug 4 is arranged on the socket head 2, and the pulling spring 5 is suspended between the mounting sleeve 3 and the spring lug 4. The specifications of the pulling spring 5 need to be determined according to the actual weight of the socket head 2.

[0015] The mounting sleeve 3 is provided with a groove 6, and the lifting spring 5 is suspended in the groove 6 to prevent the lifting spring 5 from shifting. There are two groups of grooves 6, two groups of lifting springs 5, and two groups of spring hanging ears 4.

[0016] When using it specifically: first install the installation sleeve 3 on the output shaft of the electric wrench 1, install the socket head 2 on the electric wrench 1, then insert one side of the tension spring 5 into the groove 6, and buckle the other side into the spring ear 4.

[0017] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
