referring to fig. 1-7, a safety harness for overhead working according to an embodiment of the present utility model includes a base 10, a fixing ring 18 is fixed on a lower end surface of the base 10, a safety belt of an operator is hung on the fixing ring 18 during the overhead working, two bilaterally symmetrical hooks 11 are fixed on an upper end surface of the base 10, a sleeve 13 is arranged between the two hooks 11, a pressing block 12 is arranged between the two sleeves 13, one ends of the two sleeves 13 far away from the pressing block 12 are hinged with a sealing cylinder 15, sealing rods 16 are slidably matched in the two sealing cylinders 15, and a push rod 14 is arranged on a lower side of the pressing block 12.

The two hooks 11 are arranged in a C shape, and the two closing rods 16 are respectively fixed at the lower ends of the two hooks 11.

A gap is formed between the upper ends of the two closing rods 16 and the upper ends of the hooks 11 on the corresponding sides.

The two closing cylinders 15 can abut against the upper ends of the hooks 11 on the corresponding sides.

The end surfaces of the left side and the right side of the pressing block 12 are respectively fixed with 25, and the two 25 are respectively in sliding fit with the sleeves 13 on the left side and the right side.

The base 10 is internally provided with a push rod cavity 20 with an upward opening, the push rod 14 is in sliding fit with the push rod cavity 20, a supporting spring 21 is fixed between the push rod 14 and the lower side wall of the push rod cavity 20, the upper end surface of the push rod 14 can be abutted with the periphery of the press block 12, and when the push rod 14 is abutted with the periphery of the press block 12, the press block 12 cannot slide up and down.

The front side of the ejector rod cavity 20 is communicated with a limiting rod cavity 23, a limiting rod 19 is slidably matched in the limiting rod cavity 23, a limiting cavity 24 with a forward opening is arranged in the ejector rod 14, and the rear end of the limiting rod 19 can be clamped into the limiting cavity 24.

The front end face of the limiting rod 19 is fixed with a pull rod 17, the front side part of the pull rod 17 extends forwards to the outside of the base 10, the pull rod 17 is in sliding fit with the base 10, and a limiting spring 22 is fixed between the front end face of the limiting rod 19 and the front side wall of the limiting rod cavity 23.

Embodiment one:

the safety belt on the operator is hung on the fixing ring 18.

At this time, the pull rod 17 is pulled forward, so as to drive the limit rod 19 to move forward to be far away from the limit cavity 24, and then the pressing block 12 is pressed, so that the sleeves 13 on the left side and the right side simultaneously move downward, and the closed cylinders 15 on the left side and the right side are driven to simultaneously move downward to be abutted with the lower ends of the hooks 11 on the corresponding sides.
