When sliding, the elastic deformation of the hanging sleeve 37 can be artificially hooked to the hook 36; When sliding toward the main body 21 again, the hanging sleeve 37 can automatically bounce outwards to release the locking effect on the hook 36 without affecting the normal operation of the fuse tube removal and hanging device 2 .

Method of use: when the operating rod head is in use, it is installed on the upper end of the insulating operating rod, and the suitable angle position of the fuse tube removal and hanging device 2 body 21 hinged on the rod head main body 1 is adjusted. Then the insulating operating lever is opened and stretched, and the operator lifts the operating lever so that the clamping arm ends of the first clamping arm 22 and the second clamping arm 23 face the drop switch fuse tube after the fuse is blown and dropped. When the clamp arm of the second clamp arm 23 crosses the fuse tube of the drop switch, the inner arc surface of the arc fork one 28 also leans against the outer wall of the fuse tube, and the insulating rod is pushed upward along the fuse tube to make the arc fork two 29 supports the lifting ring of the fuse tube upwards, under the pressure of the weight of the fuse tube, the gravity lowering device 25 of the fuse tube lifting device 2 will slide downward on the body 21 through the slide bar 31, and the V-shaped fork 26 The inner sides of the two forked arms produce opposing pressure on the two pulleys 30 on the first clamping arm 22 and the second clamping arm 23, so that the first clamping arm 22 and the second clamping arm 23 are folded and tightly hugged the fuse tube. Continue to lift the insulating rod upwards, and the fuse tube can be taken off from the drop switch and safely placed in the hands of the operator on the ground. The operator holds the fuse tube and lifts it so that the fuse tube no longer presses the arc-shaped fork 29, and the first clamp arm 22 and the second clamp arm 23 can be automatically opened to take off the fuse tube.

After replacing the upper fuse for the fuse tube, the fuse tube is leaned against in the clamp arm openings of the first clamp arm 22 and the second clamp arm 23 and on the arc fork one 28, and the hanging ring of the fuse tube is pressed on On the arc-shaped fork 2 29 , under the action of the gravity of the fuse tube, the V-shaped fork 26 makes the first clamping arm 22 and the second clamping arm 23 gather to embrace the fuse tube. The fuse tube is hung on the drop switch by lifting the insulating rod, and then the insulating rod is pulled down so that the hanging ring of the fuse tube no longer exerts pressure on the arc-shaped fork 29. 21 automatically springs up and slides upwards, the V-shaped fork 26 releases the restriction of the pulley 30 on the first clamp arm 22 and the second clamp arm 23, and under the action of the torsion spring 24, the first clamp arm 22 and the second clamp arm 23 Flap open to release fuse tube. Then push the pull-close ring on the fuse tube through the pull-close rod on the operating rod head to close the drop switch, and the operation process of replacing the fuse is completed. When pulling the fuse tube of the drop switch, push the closing wheel 3 of the fuse tube of the drop switch to a position close to the body 21 on the pulling rod 13 or keep it at this position, which will not affect the normal switching of the pulling rod 13 . When the fuse tube is pushed and closed, the limit steel ball on which the drop switch fuse tube closing wheel 3 is pulled is matched with the position of the limit groove 131 on the pulling rod 13 away from the body 21, and the drop switch fuse tube closing wheel 3. It can rotate freely on the pulling rod 13 without axial movement. In the process of controlling the upward turning of the fuse tube, the ring groove on the switch fuse tube closing wheel 3 and the pulling ring of the fuse tube can be dropped. Cooperating with the inner circumference can effectively prevent the pull ring on the fuse tube from moving laterally on the pull rod 13 when the ordinary pull rod 13 is used to close the switch, thereby ensuring the dynamic contact on the fuse tube when the fuse tube is pushed and closed. The head is accurately aligned with the upper fixed contact on the drop switch, thereby greatly improving the success rate of closing. It is convenient and simple to operate, saves time, and guarantees safety.
