[0028] As Figure 1 , Figure 5 , Figure 6 , Figure 7As shown, the support part 3 includes a support screw rod two 306 for moving the auxiliary clamping head 202. Two threads with different turning directions are arranged on the support screw rod two 306. One end of the support screw rod two 306 is fixedly arranged on the output shaft of the support motor two 305, and the other end of the support screw rod two 306 is fixedly arranged on the support rotating column two 307. The support rotating column two 307 is rotatably arranged on the support bottom plate 304.

[0029] As Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the support part 3 further includes a support screw rod one 302 for moving the auxiliary clamping head 202. Two threads with different turning directions are arranged on the support screw rod one 302. One end of the support screw rod one 302 is fixedly arranged on the output shaft of the support motor one 301, and the other end of the support screw rod one 302 is fixedly arranged on the support rotating column one 303. The support rotating column one 303 is rotatably arranged on the support bottom plate 304.

[0030] As Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the auxiliary clamping head 202 meshes with the threads on the support screw rod two 306 and the support screw rod one 302; the clamping nuts 102 and the clamping blocks 103 are circumferentially arrayed along the center of the clamping ring 101, and the auxiliary clamping ring 201 is circumferentially arrayed along the center of the auxiliary clamping head 202; a plurality of protruding cross bars are arranged on the contact surface of the clamping block 103 and the cable; a plurality of protruding cross bars are arranged on the contact surface of the auxiliary clamping ring 201 and the cable.

[0031] Embodiment 2:

[0032] As Figures 1 - 7 As shown, for an installation device of a cable hot-melt metal fireproof joint disclosed by the present utility model, its working principle is as follows: First, the cable to be installed with the fireproof joint passes through the centers of the auxiliary clamping head 202 and the clamping ring 101, so that the cable extends out of the auxiliary clamping ring 201. The operator manually turns the clamping nut 102, and the rotation of the clamping nut 102 drives the clamping block 103, so that the clamping block 103 approaches the cable in the clamping ring 101 and tightly adheres to the surface of the cable, fixing the cable on the clamping ring 101.

[0033] After the cable is fixed, the pulling force of the cable causes the clamping ring 101 to approach the inclined surface on the auxiliary clamping ring 201. When the clamping ring 101 and the auxiliary clamping ring 201 approach each other, the auxiliary clamping ring 201 rotates. The end of the auxiliary clamping ring 201 with a rib is pressed against the cable surface to fix the cable again. That is, the pulling force of the cable pulls the clamping ring 101 to fit with the auxiliary clamping ring 201. The clamping ring 101 pushes the auxiliary clamping ring 201, causing the auxiliary clamping ring 201 to rotate and press the cable again to complete the re-fixation. The greater the pulling force exerted by the cable on the clamping ring 101, the greater the clamping force of the auxiliary clamping ring 201 on the cable.

[0034] After the cables on the clamping part 1 and the auxiliary clamping part 2 are fixed, the motor drives the support screw 302 and the support screw 306 to rotate. The rotation of the support screw 302 and the support screw 306 causes the auxiliary clamping part 2 and the clamping part 1 symmetrically arranged on the support part 3 to approach each other, making the two cables fixed on the auxiliary clamping part 2 and the clamping part 1 approach each other, and finally aligning the end faces of the two cables. Then the operator installs the fireproof joint.

[0035] After the installation is completed, the operator turns the clamping nut 102 to drive the clamping block 103 to move the clamping block 103 away from the cable in the clamping ring 101. At this time, the cable is not fixed, the clamping ring 101 and the auxiliary clamping ring 201 are disengaged, the clamping ring 101 no longer pushes the auxiliary clamping ring 201 to rotate, and the end of the auxiliary clamping ring 201 with a rib does not contact the cable. Finally, the cable connected with the fireproof joint is pulled out to complete the whole working process.

[0036] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
