[0011] 2. Beneficial effect:

[0012] The prior art solves the technical problem that the height of the existing electric pole is not adjustable, which leads to the need to select electric poles of different heights when erecting electric wires of different heights, and is not suitable for use in various environments and is inconvenient to popularize and produce by arranging a pole body, a threaded rod, a nut sleeve and a moving plate, but the prior art has the technical problem that further fixing of the pole body is relatively complicated, the limiting assembly is arranged in the utility model, the limiting assembly is inserted into the inside of the fixed pole after the height of the pole body is adjusted, thereby increasing the supporting force of the pole body and the stability when the pole body is raised, the adjusting assembly is arranged to adjust the limiting assembly, the limiting assembly can quickly separate from the fixed pole, thereby achieving the technical problem of reducing the height of the pole body.

When the device is in use, the motor is started to drive the driving bevel gear to rotate, the driving bevel gear drives the driven bevel gear to rotate, the driven bevel gear drives the screw to rotate in the process of rotating, and then the moving block drives the rod body to move upwards along the outer side wall of the fixed rod. When the rod body is moved to the appropriate height, the limiting rod is inserted into the corresponding limiting hole, so as to realize the clamping work of the rod body and the fixed rod, and prevent the rod body from being unstable only by the moving block when it is raised.
