The top end of the sliding rod 2 is movably connected with a connecting head 3. A positioning hole is opened on the top side of the connecting head 3. The top end of the connecting head 3 is fixedly connected with a rod head 4 through a fastener. Insulating sheaths are arranged on the outer surfaces of the adjusting tube 1 and the sliding rod 2. An assembling and disassembling mechanism 6 is installed between the connecting head 3 and the sliding rod 2. The assembling and disassembling mechanism 6 includes a functional block 602 fixedly installed at the top of the sliding rod 2. Two groups of plug - in blocks 603 are symmetrically and slidably installed on the outside of the functional block 602. Two groups of positioning columns 601 are fixedly installed at the top of the sliding rod 2, and the positioning columns 601 are inserted into the positioning holes.

[0027] Among them, the assembling and disassembling mechanism 6 further includes two groups of movable grooves opened on the outer surface of the sliding rod 2. The inner wall of the movable groove is connected with a push block 604 with a downward slope and extends to the outside of the sliding rod 2. An installation groove is arranged at the top end of the sliding rod 2. A first spring 605 is fixedly installed on the inner bottom wall of the installation groove. The top end of the first spring 605 is fixedly installed with a movable block 606, and one end of each of the two groups of push blocks 604 abuts against the movable block 606, enabling the operator to quickly replace the connecting head 3 and improving the versatility of the insulating operating rod.

[0028] Among them, a limiting rod 607 is fixedly installed at the top of the movable block 606. Fixed blocks 608 are fixedly installed on the outer surfaces of the two groups of plug - in blocks 603. Two groups of second springs 609 are fixedly installed inside the functional block 602. The two ends of the second spring 609 respectively abut against the fixed block 608 and the inner wall of the functional block 602. One ends of the plug - in block 603 and the limiting rod 607 are both arc - shaped, and the arc - shaped ends of the plug - in block 603 are all attached to the outer surface of the limiting rod 607, realizing quick assembly and disassembly, saving the time required for operation, and improving the reliability of the device in use.

[0029] Among them, a fixing groove 10 matching the functional block 602 is opened at the bottom of the connecting head 3. Inclined surfaces facing the rod head 4 are opened on the outer surfaces of the two groups of plug - in blocks 603. Two groups of plug - in slots are opened on the inner wall of the fixing groove 10, and the two groups of plug - in slots are all adapted to the plug - in blocks 603, with reliable connection and effectively improving the safety of the operator.

[0030] Among them, the lifting mechanism 5 includes a screw rod 501. The top end of the screw rod 501 is threadedly connected to the nut inside the sliding rod 2. The bottom end of the screw rod 501 is rotatably installed inside the bottom end of the adjusting pipe 1. A worm gear 502 is installed at the bottom end of the screw rod 501. A worm 503 is engaged with one side of the worm gear 502. One end of the worm 503 extends to the outside of the adjusting pipe 1. The settings of the worm gear 502 and the worm 503 not only play a role in lifting, but also have a self-locking function, making it more stable during use.

[0031] Among them, a retaining ring 504 is fixedly installed inside the bottom end pipe body of the adjusting pipe 1, and the retaining ring 504 is fixed at the top ends of the worm gear 502 and the worm 503. A circular handle 505 is fixedly installed at the other end of the worm 503. Just by shaking the circular handle 505, the lifting of the sliding rod 2 can be directly adjusted, which is convenient and fast.

[0032] Among them, a chute 7 is vertically opened on one side of the sliding rod 2. A limiting block 8 is slidably connected inside the chute 7. A threaded column is fixedly connected to one side of the limiting block 8, and the threaded column extends to the outside of the adjusting pipe 1. One end of the threaded column outside the adjusting pipe 1 is connected with a knob 9, which can fix the sliding rod 2 to prevent rotation and improve safety.

[0033] Working principle of this embodiment: Before the insulating operating rod is used, first rotate the circular handle 505 at the bottom end of the adjusting pipe 1. Under the action of the worm gear 502 and the worm 503, the screw rod 501 at the center of the worm gear 502 rotates and drives the sliding rod 2 to move upward to a suitable height position. During the upward movement, to prevent the sliding rod 2 from rotating, a limiting block 8 is connected in the chute 7 on one side of the sliding rod 2 and fixed by the knob 9, which can effectively prevent the sliding rod 2 from rotating; when it is necessary to replace the rod head 4 at the top end of the insulating operating rod, the push block 604 can be pressed to drive the movable block 606 to move downward. The downward movement of the movable block 606 can drive the limiting rod 607 to move, so that the limiting rod 607 disengages from the inside of the functional block 602. When the limiting rod 607 disengages from the inside of the functional block 602, the fixed block 608 and the plug-in block 603 can be pushed by the spring two 609 to move, and then the plug-in block 603 disengages from the inside of the plug-in slot, so that the connection head 3 and the rod head 4 connected to the connection head 3 can be quickly disassembled. Then, a suitable rod head 4 is selected and inserted into the top end of the sliding rod 2 through the positioning post 601. During the insertion process, the plug-in block 603 will slide into the plug-in slots on both sides of the fixed slot 10 and be fixed, solving the problem that the traditional insulating operating rod is inconvenient to replace the rod head 4.
