The above-mentioned auxiliary tool for making intermediate joints of cables, the base is provided with four brackets, a connecting seat is fixedly arranged in the middle of the base, a bearing is respectively embedded in the left and right end surfaces of the connecting seat, and the bases on the left and right sides of the connecting seat A lead screw is respectively arranged, and the inner end of the lead screw is fitted with a bearing, and two brackets are installed on each lead screw through a slide block.

In the aforementioned auxiliary tool for making intermediate joints of cables, a height adjustment mechanism for adjusting the height of cables is arranged between the iron plate and the hoop.

Due to the adoption of the above technical solutions, the technical progress achieved by the utility model is as follows.

When the utility model is in use, the tightness of the hoop can be adjusted according to the thickness of the cable to ensure that cables of different specifications can be fixed, and the height of the support frame can be adjusted according to the needs of the operator, so that the work can be carried out more comfortably and conveniently. At the same time, according to the position of the intermediate joint, the left and right positions of the hoop on the base can be changed by operating the handle, which not only ensures the stability of the cable head during the production process of the cable intermediate joint, but also improves the production quality of the cable intermediate joint.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

An auxiliary tool for making cable intermediate joints, its structure is shown in Figure 1 and Figure 2, including a base 1 and a bracket 2, the base 1 is set on the ground for stabilization. The base 1 is composed of two rectangular parallelepiped channel steels with the same height. The grooves on both sides of the channel steel are provided with slideways 3 for placing the bracket 2 and allowing the bracket 2 to move left and right in the base.

The bracket 2 includes an iron plate 4, a slider 5 at the bottom of the iron plate 4, and a hoop 6 for fixing cables above the iron plate 4. A height adjustment mechanism that can adjust the height of the hoop is arranged between the iron plate 4 and the hoop 6.
