[0024] Please see Figure 1 and Figure 3 The two telescopic outriggers 5 at the bottom of the second support plate 2 are each equipped with a first traveling wheel 7 and a second traveling wheel 8. The first traveling wheel 7 and the second traveling wheel 8 are respectively installed on the upper rod 501 and the lower rod 502. The setting of the first traveling wheel 7 and the second traveling wheel 8 allows personnel to push the tool to move on the ground, reducing the difficulty of carrying and providing users with new carrying options.
[0025] The working principle and usage process of this utility model are as follows: When unfolding, first unfold the first support plate 1 relative to the second support plate 2, then rotate the tool 180° and place it on the ground. Then open the telescopic support legs 5 at the bottom of the first support plate 1 and the second support plate 2. Then rotate the adjusting wheel 604, which drives the threaded rod 603 to pass through the second threaded sleeve 602 and the first threaded sleeve 601 in sequence, thereby locking the two support plates. Then adjust the length of the telescopic support leg 5. (When the span between the two fixed ladder rods 11 is large after adjustment, the movable ladder rod 12 can be inserted into the threaded hole 10 on one side of the telescopic support leg 5, and then rotate...) Connect to the threaded hole 10 of another telescopic support leg 5 on the same side to reduce the span between adjacent ladder bars, making it easier for users to climb. After adjustment, lock it with bolt 9. Finally, rotate the tool 180° and place it flat on the ground for use. After use, first store the two telescopic support legs 5 to their shortest length, and then fold the telescopic support legs 5 to the bottom of the support plate. At this time, the telescopic support legs 5 will be attracted by the magnetic block 14 installed at the bottom of the support plate. Then fold the first support plate 1 and the second support plate 2. Move the tool on the ground by the walking wheels installed on the telescopic support legs 5 at the bottom of the second support plate 2, or carry the folded tool by hand.
