It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] See Figure 1 , Figure 2 and Figure 3 This is a schematic diagram of the structure of this patent. An insulating operating rod for power construction includes a square tube 1 and a screw 6. A connecting ring 2 is fixedly installed at the bottom of the outer side wall of the square tube 1. A bearing 3 is fixedly installed on the inner side wall of the connecting ring 2. A rotating tube 4 is fixedly installed at the top of the inner ring of the bearing 3. A nut 5 is fixedly installed at the top of the rotating tube 4. Both the rotating tube 4 and the nut 5 are located inside the square tube 1. The bottom end of the screw 6 extends to the lower inner side of the square tube 1. The thread on the side wall of the screw 6 is screwed into the thread on the inner side wall of the nut 5.

[0021] A limiting slider 7 is fixedly installed on the side wall of the screw 6, and the outer side wall of the limiting slider 7 slides in relative contact with the inner side wall of the square tube 1.

[0022] The limiting slider 7 includes a square block 8, with a round hole 13 in the middle of the square block 8. The inner sidewall of the round hole 13 is fixedly installed on the sidewall of the screw 6. The left and right ends of the outer sidewall of the square block 8 are provided with mounting grooves 9. The mounting grooves 9 are connected to the limiting wheel 10 through a rotating shaft. The left and right ends of the inner sidewall of the square tube 1 are provided with wheel grooves 11. The wheel edge of the limiting wheel 10 is rolled and installed in the wheel groove 11. The outer sidewall of the square block 8 does not contact the inner sidewall of the square tube 1.

[0023] By rolling the limit wheel 10 within the wheel groove 11, the sliding limit in the traditional lead screw system can be changed to a rolling limit, which can greatly reduce friction and facilitate the rotation of the nut 5 by personnel.

[0024] A hook 12 is fixedly installed at the top of the screw 6.

[0025] Specifically, the top of the wheel groove 11 is in the open state.

[0027] Specifically, neither the rotating tube 4 nor the nut 5 comes into contact with the inner wall of the square tube 1.

[0028] Specifically, the inner wall of the round hole 13 is provided with connecting grooves 14 at all four ends, and the screw 6 is provided with connecting grooves 14 at all four ends.

[0029] The eight connecting grooves 14 are positioned in pairs, and the adhesives are positioned in the two connected connecting grooves 14, so as to facilitate the fixed connection of the round hole 13 and the screw rod 6.

[0030] Specifically, the inner side wall of the inner ring of the bearing 3 is fixedly installed with a T-shaped column 15, and the end of the T-shaped column 15 is located at the lower side of the bearing 3.

[0031] The T-shaped column 15 is arranged to facilitate the rotation of the inner ring of the bearing 3.

[0032] Specifically, the T-shaped column 15, the square tube 1, the connecting ring 2 and the bearing 3 are all externally provided with a glass fiber reinforced epoxy resin layer 16.

[0033] The glass fiber reinforced epoxy resin layer 16 has very strong insulation performance.

[0034] Working principle: when in use, the bottom end of the square tube is located near the eyes of the staff, then the T-shaped column 15 is rotated, the T-shaped column 15 drives the rotating tube 4 and the nut 5 through the inner ring of the bearing 3, and since the limiting wheel 10 rolls in the wheel groove 11, the screw rod 6 cannot rotate and can only move upwards to adjust the height of the hook 12.

[0035] It should be noted that the device structure and the drawings of the present patent mainly describe the principle of the present patent, and the arrangement of the power mechanism, the power supply system and the control system of the device is not completely described in the technical principle of the design, and the specific power mechanism, power supply system and control system can be clearly obtained by the person skilled in the art under the premise of understanding the principle of the above patent.

[0036] The present patent connects the bearing at the bottom end of the square tube through the connecting ring, the inner ring of the bearing is connected with the nut through the rotating tube, and the inner side wall of the nut is connected with the screw rod, at this time, only the inner ring of the bearing needs to be rotated to drive the screw rod and the hook at the top to move up and down, in use, the bottom end of the square tube can be located near the eyes of the staff, then the operation is performed, the height position of the hook is calibrated, the traditional sliding limit is changed into rolling limit by the square block and the limiting wheels on both sides, the friction effect is greatly reduced, and the personnel operation is facilitated.
