Problems solved by technology

[0002] Power pull rods are frequently used in the process of transmission lines and equipment operation and maintenance. In order to facilitate the storage and carrying of power pull rods, the power pull rods are generally designed as a three-section or four-section pull rod single-unit structure. The docking and assembly steps are cumbersome; in addition, the tie rods are easily lost after being disassembled, and three or four tie rods need to be bundled together, which increases the workload of management personnel

Abstract

An electric pull rod is used for solving the problem that after a traditional screw opening pull rod is split, pull rod single bodies can be lost easily. The electric pull rod comprises a set of pull rod single bodies, and the number of the pull rod single bodies is three or more. The electric pull rod is characterized in that the two ends of the pull rod single bodies are provided with square connecting seats, two adjacent pull rod single bodies are connected through hinged mechanisms arranged on the square connecting seats, a positioning and locking mechanism is arranged between two adjacent pull rod single bodies, and the positioning and locking mechanisms and the hinged mechanisms are arranged on the two opposite side faces of the square connecting seats. The electric pull rod has the advantages of being simple in structure and convenient to assemble, the occupied space is small, storing and carrying are convenient, and standardized management to electric tools can be better achieved.

Description

technical field [0001] The invention relates to an electric pull rod, in particular to a foldable and stored electric pull rod, which belongs to the technical field of basic electrical components. Background technique [0002] Power pull rods are frequently used in the process of transmission lines and equipment operation and maintenance. In order to facilitate the storage and carrying of power pull rods, the power pull rods are generally designed as a three-section or four-section pull rod single-unit structure. The docking and assembly steps are cumbersome; in addition, the tie rods are easily lost after being disassembled, and three or four tie rods need to be bundled together, which increases the workload of management personnel. Contents of the invention [0003] The object of the present invention is to aim at the disadvantages of the prior art, and provide an electric pull rod with simple structure, convenient assembly, and avoiding the loss of the pull rod after be...
