[0035] As a preferred embodiment, the limiting component is a latch 6, a through hole is provided on the knob I5, and a pin hole 102 is provided on the support rod 1. The latch 6 passes through the through hole and fits in the pin hole 102. When the knob I5 needs to be rotated, the latch 6 can be pulled out.

[0036] As a preferred embodiment, the function of the above-mentioned limiting assembly is to limit the rotation of the knob I5, and is not limited to the pin limiting, but can also be limited by bolts.

[0037] As a preferred embodiment, a threaded rod Ⅱ14 is rotatably installed at the lower end of the partition 101, and one of the bevel gears of the bevel gear set Ⅲ15 is sleeved on the threaded rod Ⅱ14. When the bevel gear rotates, it can drive the threaded rod Ⅱ14 to rotate. The other bevel gear is rotatably installed inside the support rod 1 through the rotating shaft Ⅲ16. The rotation of the rotating shaft Ⅲ16 can drive the bevel gear to rotate.

[0039] As a preferred embodiment, the end of the fixing pile 18 close to the ground is conical, and the conical tip can reduce the resistance of the fixing pile 18 when inserted into the soil.

[0040] The operating principle of this utility model:

[0041] When in use, first turn the knob III17, and drive the bevel gear set III15 to start transmission through the rotating shaft III16, drive the threaded rod II14 to start rotating, and the fixed pile 18 moves downward and pushes into the soil to enhance the stability of the climbing frame. Then stop the rotation of the knob III17. Before the worker climbs up the climbing frame, he puts the tool into the tool box 13, tightens the fastening bolt 124 and the fastening nut 125, so that the clamping plate 121 tightly clamps the threaded sleeve 8, and then the bevel gear set II7 fixed with the threaded sleeve 8 cannot be transmitted. At this time, turn the knob I5, and drive the bevel gear set I3 to start transmission through the rotating shaft I4, drive the threaded rod I2 to rotate, and under the support of the retaining ring 9, the working box 13 is sent to the approximate height position of the construction, and then the pin 6 is inserted into the pin hole 102, so that the bevel gear set I 3 cannot transmit, and thus the threaded rod I2 cannot rotate. When the worker climbs to the height of the tool box 13, he loosens the fastening bolts 124 and the fastening nuts 125, so that the distance between the clamping plates 121 becomes larger and no longer tightly clamps the threaded sleeve 8. At this time, he turns the knob II11, and drives the bevel gear set II7 through the rotating shaft II10 to start transmission. The threaded sleeve 8 rotates, and the threaded rod I2 cannot rotate at this time. Under the support of the retaining ring 9, the tool box 13 rises or falls with the rotation of the threaded sleeve 8 until it is adjusted to the precise position for construction. After the construction is completed, he tightens the fastening bolts 124 and the fastening nuts 125 again, climbs down the climbing frame, pulls out the pin 6, and turns the knob I5 to make the tool box 13 fall. He takes out the tools and turns the knob III17. The fixed pile 18 moves up and off the ground, and the use is finished.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
