The oil chamber 302 is a closed chamber and is only communicated with the oil outlet hole 05.

The specific implementation mode and principle are as follows:

during the utility model discloses a device, to insert the towing ring 02 and inject in pipeline 1, support the towing ring 01 and support on the cement wall at the pipeline mouth in the well, then twist fixed hand wheel 06, through driving gear 104 and the meshing of drive gear 103, drive gear 103 and the meshing of bevel gear 102, bevel gear 102 cover is outside screw thread telescopic link 101 and rather than threaded connection, final drive screw thread telescopic link 101 stretches out, support the firmware 107 top on the pipeline 1 inner wall of opposite side with screw thread telescopic link 101's outer end, ensure that the device is firm.

When the cable is laid, the cable is abutted against the abutting wheel 03, and the abutting wheel 03 rotates like a pulley to assist in the laying. When the cable is clamped, the force between the cable and the supporting wheel 03 is increased, so that the supporting wheel 03 sinks inwards, the angle is adjusted, and the cable is promoted to be laid. If the cable is still clamped, as long as the motor at the terminal end is not stopped, the force between the cable and the resisting wheel 03 is continuously increased, and finally the expansion bracket 04 presses the pressing rod 204 to move downwards, so that the first piston 205 moves downwards to change the air pressure in the closed cavity 208, so that the second piston 206 in the rack movable cavity 209 moves outwards, and the rack 207 is driven to move to drive the driving gear 305 to rotate;

the driving gear 305 rotates to drive the threaded push rod 304 in the driving gear to ascend, the threaded push rod 304 ascends to enable the piston III 303 to move upwards, lubricating oil in the oil cavity 302 is extruded out at the corresponding position, the connecting position is lubricated, and cables can conveniently and smoothly pass through the connecting position.

After the force between the cable and the resisting wheel 03 is reduced, the buffer spring 203 enables the expansion bracket 04 and the resisting wheel 03 to ascend, the pressing rod 204 is loosened, the pressing rod 204 resets under the action of a reset spring (not shown in the figure), so that the first piston 205 resets, the second piston 206 in the rack movable cavity 209 resets through air pressure change, the driving rack 207 moves back, but the one-way bearing 306 is arranged in the driving gear 305, so that the driving rack 207 only moves back to enable the driving gear 305 and the one-way bearing 306 to rotate relatively, and the threaded push rod 304 cannot be driven to descend.
