In the embodiment, the folding section 2 rotationally connects the folding pipes 21 at the head and tail to the handheld piece 1 and the operating piece 3, so as to facilitate the overall storage of the folding pipes 21.

[0034] In some embodiments, the upper end of the first section of the folding tube 21 is rotationally connected with the handheld piece 1, the adjacent two folding tubes 21, and the lower end of the folding tube 21 of the tail section is rotationally connected with the operating piece 3 through the rotary connecting piece 4. Preferably, the rotary connecting piece 4 is a rotary connecting shaft. According to the use requirements, the rotary connecting shaft is connected to act on the connection of each part. The handheld piece 1, the folding tube 21, and the operating piece 3 are punched and installed. The upper end of the folding tube 21 of the first section is rotationally connected with the handheld piece 1 through the rotary connecting shaft. The adjacent two folding tubes 21 are rotationally connected through the rotary connecting shaft. The lower end of the folding tube 21 of the tail section is rotationally connected with the operating piece 3 through the rotary connecting shaft. It should be noted that the connection between the folding tube 21 of the tail section and the operating piece 3 can be selected as the rotary connecting shaft connection, and the connection between the operating piece 3 and the folding tube 21 must be firm and reliable. The shape of the rotary connecting shaft is wide at both ends and thin in the middle. When the folding tube 21 is punched and installed, the two ends of the rotary connecting shaft need to be larger than the manufacturing hole of the folding tube 21.

In the use state and when all the folding sections 2 are unfolded, the handheld square tube 11 and the folding sections 2 are arranged perpendicularly, that is, the handheld square tube 11 and the folding sections 2 are in T shape.

[0036] In some embodiments, the handheld square tube 11 is provided with a first opening 111 on one side along the length direction thereof. The first opening 111 extends to the two opposite sides along the length direction of the handheld square tube 11. The rotary connecting piece 4, that is, the rotary connecting shaft, is installed in the first opening 111. The two ends of the rotary connecting shaft are respectively installed on the two opposite side walls of the first opening 111. The upper end of the folding tube 21 of the first section extends into the first opening 111 and is rotationally connected with the handheld square tube 11 through the rotary connecting shaft. The folding tube 21 of the first section is matched with the first opening 111 of the handheld square tube 11. The length of the handheld square tube 11 should be longer than the length of the folding tube 21 of the first section. In this way, the folding tube 21 of the first section can be folded into the first opening 111 of the handheld square tube 11.

[0037] Please continue to refer to Figures 1-3 and Figure 5As shown in the figure, in this embodiment, it also needs to be pointed out that the folding section 2 is designed according to the actual use environment, the inspection opening of the manhole cover is different, and the number of the folding pipe 21 is determined according to different application scenarios.
