[0002] Heat-shrinkable insulation tubing, also known as heat-shrinkable insulation tubing, is a material widely used for wire and cable insulation protection. Primarily made from thermoplastic materials such as polyolefin (PE), it undergoes a special radiation cross-linking process, imparting the material's ability to shrink when heated. Heat-shrinkable insulation tubing rapidly shrinks at a certain temperature, tightly wrapping around the surface of the object being protected to form a solid protective layer with excellent insulation, waterproofing, and sealing properties.

[0003] A Chinese patent publication (publication number: CN219996999U) discloses a device for testing the heat shrinkage performance of a heat shrinkable tube, comprising a support plate, wherein the bottom surface of the support plate has two pairs of symmetrically distributed fixed mounting plates, and the top surface is provided with a combustion instrument body, and the back surfaces of the two pairs of mounting plates are provided with tooth grooves, and gears are placed on the inner sides of the tooth grooves; in the utility model, a device for testing the heat shrinkage performance of a heat shrinkable tube can adjust the use angle of the fixed tube by the coordinated use of the gears, connecting rods, positioning plates and return springs, which is beneficial for the staff to place the device on uneven ground for use and prevent the device from shaking, and at the same time, the coordinated use of the fixed tube, the adjustment plate and the bolt can facilitate the adjustment of the length of the support leg, which is beneficial for the staff to adjust the length of the support leg according to the grooves on the ground, so that the device is convenient to be placed on uneven ground for use;

[0004] However, when the above technology is used to perform fixed testing on some heat shrink tubes with larger or smaller diameters, it is difficult to fix them because the diameters of the testing slots are different. If the heat shrink tube cannot be stably fixed, the heat shrink tube will be offset during testing, and accurate data cannot be obtained.

[0005] Therefore, a heat shrinkage detection device for a heat shrinkage insulation box is proposed. Utility Model Content

By setting the limit ring 5, the height of the up and down movement of the connecting plate 303 can be limited to ensure the normal use of the entire device.

[0030] Example 2

[0031] like Figure 4-5As shown, in one embodiment, the top of the operating table 1 is movably connected with a detection slot 8, and the left and right sides of the top of the operating table 1 are fixedly connected with positioning blocks 9.
