[0037] Working principle: Before using the alignment device for the cable butt joint of the sulfur hexafluoride electrical cabinet, the overall situation of the device needs to be checked to determine whether it can work normally, and according to Figure 1 - Figure 5 As shown, first, the sleeve 101 is placed between the first clamping plate 203 and the second clamping plate 204, and then the connecting sleeve 205 is pushed to slide together with the second clamping plate 204 in the stepped groove, so that the sleeve 101 is clamped between the first clamping plate 203 and the second clamping plate 204;

[0038] During the movement of the second clamping plate 204, the rack 210 drives the gear 208 to rotate, so that the connecting shaft 206 and the movable shaft 212 rotate together.

[0040] When it is necessary to release the locking of the sleeve 101, only the pull ring 217 needs to be pulled to make the movable shaft 212 slide with the connecting shaft 206, so that the limiting disc 213 moves away from the connecting shaft 206, and then the mounting disc 215 drives the clamping hook 220 to move outward through the connecting rod 219, until the clamping hook 220 is misaligned with the bevel gear ring 211, so that the connecting shaft 206 can rotate freely. At this time, the second clamping plate 204 can move freely, so that the sleeve 101 can be quickly disassembled;

[0041] After the sleeve 101 is fixed, the cable is placed between the driving roller 303 and the squeezing roller 307 by being attached to the bottom of the side plate 301, at this time the first motor 302 is started to make the driving roller 303 rotate, so that the cable is directly sent into the sleeve 101, avoiding the operation of fixing first and then butt joint.
