Problems solved by technology

[0002] During the construction or inspection of power system line laying, whether the line is tight is directly related to the normal use of the entire power line. If the power line is too loose, it will swing due to excessive sag, collide with each other and short-circuit. If the power line is too tight, then It is easy to break the wire or pull the pole. The wire tightening pliers play the role of tightening the wires. It can keep the power line at an appropriate tightness. However, the existing wire tightening pliers are more troublesome to use

Abstract

The invention relates to a wire tightening pliers, which comprises a base, a trapezoidal installation groove arranged in the middle of the base, a left slider and a right slider which are slidably arranged on the left and right side walls of the installation groove and have the same structure, and respectively arranged The extension spring between the left and right sliders and the top of the base is provided with grooves for the passage of wires on the corresponding side walls of the left and right sliders; the present invention makes the left and right sliders in a trapezoidal Slide in the installation groove, and then use the tension spring to make the left and right sliders always have an upward movement force. When the wires are inserted into the grooves of the left and right sliders from top to bottom, the left and right sliders will move under the action of the tension springs. It will hold the wire tightly to realize the function of preventing the wire from retracting. This method of holding the wire has a simple structure and can realize automatic tightening, which is very convenient to use.

Description

technical field [0001] The invention relates to electric fittings, in particular to a wire tightener. Background technique [0002] During the construction or inspection of power system line laying, whether the line is tight is directly related to the normal use of the entire power line. If the power line is too loose, it will swing due to excessive sag, collide with each other and short-circuit. If the power line is too tight, then It is easy to break the wire or break the wire pole. The wire tightening pliers play the role of tightening the wires, and it can keep the power line under a suitable tightness. However, the current existing wire tightening pliers are more troublesome to use. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a simple-to-use wire tightening pliers. [0004] The technical solution adopted in the present invention is: a wire tightening pliers, which includes a base, a trapezoidal mounting groove ...
