DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: an auxiliary tool for making and installing a cold shrink cable terminal joint, comprising an auxiliary tool handle 1, an installation rod 2, a cable joint pre-expansion piece 3, an elastic material 4, a spiral support strip 5, a support assembly 6, an installation assembly 7 and a functional groove 8. The auxiliary tool handle 1 is arranged on the left side of the installation rod 2, and a functional groove 8 is also opened at the right end of the installation rod 2. The support assembly 6 is arranged in the functional groove 8, and the support assembly 6 is connected to the installation assembly 7. The inner layer of the cable joint pre-expansion piece 3 is provided with an elastic material 4, and a spiral support strip 5 is added to the elastic material 4 for support. The support assembly 6 includes a sleeve 61, a support plate 62, a spring ring 63, an inner rod 64, a small plug 65, a connecting rod 66 and an elastic plate 67, an inner rod 64 is connected to the sleeve 61, and a spring ring 63 is arranged between the upper and lower ends of the sleeve 61, a support plate 62 is installed on the inner rod 64, the elastic plate 67 is divided into two parts, and the elastic plates 67 of the two parts are both arranged on the spring ring 63, and the connecting rod 66 is assembled on the right side of the elastic plate 67, the installation component 7 includes a rear plate 71, a clamp 72, a small hinge 73, a movable plate 74, a limiting strip 75 and a movable spring rod 76, a clamp 72 is arranged on the surface of the rear plate 71, and the rear side of the rear plate 71 is connected to the top of the connecting rod 66, a small hinge 73 is assembled on the clamp 72, and the small hinge 73 divides the front end part of the clamp 72 into a movable plate 74, and a plurality of limiting strips 75 are added to the movable plate 74.

[0020] As the first embodiment of the utility model: the spring ring 63 is welded to the bottom of the sleeve 61, and the bottom side of the spring ring 63 is connected to the inner rod 64. The design uses the spring ring 63 to allow the inner rod 64 to stretch up and down in the sleeve 61 to achieve the supporting effect. The width of the functional slot 8 opened on the mounting rod 2 matches the size of the sleeve 61 in the support assembly 6. The design places the support assembly 6 by opening the functional slot 8, and the structure is reasonable. A small plug block 65 is also added to the left part of the connecting rod 66, and the small plug block 65 is located between the upper and lower elastic plates 67. The design adds a small plug Block 65 is used to push the upper and lower parts of the elastic plate 67 apart, which helps the spring ring 63 connected to the elastic plate 67 to achieve extended support for the upper and lower parts of the inner rod 64. Multiple limiting strips 75 are fixed to the surface of the clamp 72 by welding. This design prevents the movable plate 74 from opening by setting the limiting strips 75, and cannot achieve the clamping effect on the spiral support strip 5. Active spring rods 76 are added to the upper and lower ends of the small hinge 73, and the active spring rods 76 are also connected to the movable plate 74. This design further enhances the flexibility of opening and closing of the movable plate 74 on the clamp 72 by adding active spring rods 76.

[0021] As a second embodiment of the present invention: when connecting the cable, the construction personnel first hold the cable connector pre-expanding part 3, and then insert the installation rod 2 into the cable connector pre-expanding part 3 through the auxiliary tool handle 1, and the installation component 7 in the installation rod 2 will contact the spiral support bar 5. After the movable plate 74 contacts the spiral support bar 5, due to the extrusion effect, the small hinge 73 and the movable spring rod 76 will fold the movable plate 74 backwards, so that the spiral support bar 5 will be wrapped in the clamp 72. After the rear plate 71 contacts the spiral support bar 5, similarly, under the extrusion effect, the connecting rod 66 will be squeezed to the left, and the small insert block 65 will squeeze the upper and lower parts of the elastic plate 67, so that the elastic plate 67 will follow the spring ring 63 during the separation process. By compressing the upper and lower sides, the inner rod 64 is compressed by the elastic potential energy of the spring coil 63 to extend outward from the sleeve 61. In this way, with the support of the inner rod 64, the support plate 62 will support the elastic material 4 on the inner side of the cable connector pre-expansion part 3. With the support of the support plate 62, the spiral support strip 5 does not need support. At this time, the construction personnel connect the cable line to the supported cable connector pre-expansion part 3, and then quickly withdraw the installation rod 2. The movable plate 74 cannot be folded outward due to the obstruction of the limiting strip 75. In this way, the spiral support strip 5 is taken away by the clamp 72. The entire cable connector pre-expansion part 3 loses the support of the support assembly 6 and the spiral support strip 5, and the elastic material 4 will naturally shrink, so that the cables will be well connected together.
