Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of folding stair climbing tower wagon as shown in Figs. 1-3, including holder 1, the two of 1 lower end of the holder
A inserting column interts sliding sleeve 16, sliding inner sleeve 5, supporting sleeve 6, tooth pipe sleeve 7, torsional spring 8 and tripod 9, and the two of 1 lower end of holder successively
A inserting column end is rotatably connected on the both ends of shovel board 10, and the torsional spring 8 is arranged in the inside of tripod 9, and the lower end of torsional spring 8 is fixed
In tripod 9, the tooth pipe sleeve 7 is fixed by screws on the inserting column of 1 lower end of holder, and the upper end of torsional spring 8 is fixedly connected on
It on screw, is connected by middle connecting tube 4 between the sliding sleeve 16, the outside of the sliding sleeve 16 connects the upper of connecting rod 11
End, the lower end of the connecting rod 11 are connected in shovel board 10, and the upper end of the side connecting support seat 12 of the supporting sleeve 6 is described
The lower end of the side connection moving block 13 of tripod 9, the lower end of the support base 12 is connected to the lower part of moving block 13, and is located at foot
