Abstract

The present invention relates to the pre-twisted helical fitting installation technology field, especially to a pre-twisted device. The pre-twisted device comprises a handle piece, an expansion piece, a crimping piece and a withstanding piece. One end of the expansion piece is connected with the crimping piece, the other end of the expansion piece is movably connected with the handle piece, the crimping piece has a first arc-shaped structure, pre-twisted strip jacks are arranged at two sides of the first arc-shaped structure, the withstanding piece is provided with a second arc-shaped structure being corresponding matching to the first arc-shaped structure, and the expansion piece performs telescoping movement under the driving of the handle piece to allow the first arc-shaped structure and the second arc-shaped structure to perform movement facing each other or separating from each other. The technical problem can be solved that a pre-twisted device is difficult to install by hands in the prior art, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of installation of pre-twisted hardware, in particular to a pre-twisted device. Background technique [0002] At present, all kinds of traditional fittings widely used in power and communication systems at home and abroad have been largely replaced by pre-twisted fittings with better performance, more stable operation and easier installation. However, there are also outstanding problems in the use of pre-twisted fittings, especially in the installation process: [0003] 1) Since the design of the pre-twisted fittings adopts the principle of preset internal stress in the spiral empty pipe, considering its application object is mainly aimed at the connection, connection, fixing and mounting of power transmission and distribution lines and communication lines, combined with the application object and The slightly flexible general characteristics of the pre-twisted fittings, coupled with the unique spiral hollo...
