The same principle is adopted, so that the downward moving process of the lifting operation platform of the tower mast structure can be realized.
As shown in fig. 6 and 7, the working process of the telescopic oil pump is as follows: in this embodiment, the end face of the electromagnet 18 is in a folded shape, the included angle formed between the folded surfaces is the same as the included angle formed between two adjacent side surfaces on the tower body, the end face of the electromagnet 18 faces the tower body, when the lifting operation platform needs to be fixed on the tower body, the output shaft 13 stretches out, the end face of the electromagnet 18 contacts with the tower body, the electromagnet 18 is electrified, the electromagnet 18 can be adsorbed on the tower body, and when the lifting mechanism needs to be moved, the electromagnet 18 is powered off, and the output shaft 13 retracts. Because the tower body is of a structure with a narrow upper part and a wide lower part, the electromagnet 18 is a folded surface and is matched with the shape of the tower body, and therefore, when the electromagnet 18 is powered off under the unexpected condition, the electromagnet 18 cannot slide down along the tower body in a short time.
