[0040] In this embodiment, preferably, the top of the pedal 1071 is processed with anti-skid patterns to make the pedal 1071 more anti-skid, and the vertical rod 1075 is arranged on the inner side of the plurality of limit tubes 1074, and the bottom of the limit piece 1076 fixed to the top of the vertical rod 1075 and the top of the limit piece 1076 fixed to the bottom of the vertical rod 1075 are respectively attached to the top of the top limit tube 1074 and the bottom of the bottom limit tube 1074, that is, the limit piece fixed to the top of the vertical rod 1075 The lower surface of the stopper 1076 is fitted to the top of the stopper 1074 located at the top end among the multiple stopper tubes 1074 arranged on the outer wall of the vertical rod 1075, and the upper surface of the stopper 1076 fixed to the bottom end of the vertical rod 1075 is fitted to the bottom end of the stopper tube 1074 located at the bottom end among the multiple stopper tubes 1074 arranged on the outer wall of the vertical rod 1075.

Since the reinforcing frame 104 is arranged at the inner top end of the support pole 102, there is no need to worry that the support pole 102 will damage the corn plants planted on the top of the ridge when erecting the support pole 102, and the ladder frame 101 and the support pole 102 can be spread out in a herringbone shape to make the erected ladder frame 101 more stable. After supporting the ladder frame 101, first step on the pedal 1071 in the climbing member 107 at the bottom. If the pedal 1071 is not If it remains level with the ground, under the action of the applied pedaling force, the pedal 1071 will be driven to rotate with the shaft head 1073 as the axis, so that the support angle of the pedal 1071 can be adjusted, so that the pedal 1071 and the ground are kept level. When the pedal 1071 at the bottom rotates with the shaft head 1073 as the axis, the limiting plate 1076 at the bottom end of the vertical rod 1075 will be pressed through the limiting tube 1074, so that the vertical rod 1075 is driven to move as a whole through the limiting plate 1076, so that the support angles of the pedals 1071 in multiple climbing components 107 can be adjusted synchronously, so that all the pedals 1071 are kept level with the ground, which is convenient for subsequent climbing.

[0042] Embodiment 2

[0043] See also Figure 1 and Figure 6-Figure 7 As shown, on the basis of the first embodiment, the moving mechanism 2 includes a support plate 201, and a pressure plate 202 is fixedly connected to the outer side of the support plate 201, and the pressure plate 202 is used to drive the support plate 201 to move. The bottom end of the support plate 201 is threadedly connected with a universal wheel 203 through a bolt, and the universal wheel 203 is used to drive the support plate 201 to move, so that the support mechanism 1 can be driven to move as a whole through the support plate 201, which is convenient for walking between the ridges of the corn field. A blocking rod 204 is arranged on the outer side of the universal wheel 203, and the blocking rod 204 is used to clamp the support plate 201.

[0044] In this embodiment, preferably, a torsion spring is processed at the connection between the blocking rod 204 and the ladder frame 101, and the torsion spring is used to reset the blocking rod 204.

[0045] In summary, when it is necessary to drive the support mechanism 1 to move in the corn field, the pressure plate 202 in the moving mechanism 2 is stepped down, and while stepping on the pressure plate 202, the support mechanism 1 is lifted up by hand. By stepping on the pressure plate 202, the support plate 201 can be driven to slide downward, and the support plate 201 can be slid to the inner bottom end of the slideway opened at the bottom end of the side of the ladder frame 101. Through the mutual cooperation between the blocking rod 204 and the pressure rod 205, the top of the support plate 201 that slides to the bottom end of the slideway can be limited to prevent the support plate 201 from sliding back to the inner side of the ladder frame 101, and then the support plate 201 on the other side of the ladder frame 101 can be slid to the slideway opened at the bottom end of the other side of the ladder frame 101 in the same way. The bottom end of the ladder frame 101 can be supported by the two universal wheels 203, so that the two universal wheels 203 can be extended from the bottom end of the ladder frame 101, which makes it easy to carry the support mechanism 1 to walk between the ridges of the corn field. When the universal wheels 203 need to be retracted to the inner bottom end of the ladder frame 101, the fastening nut 206 is loosened so that the pressure rod 205 can rotate on the side of the ladder frame 101. After the fastening nut 206 cancels the clamping of the pressure rod 205, the support plate 201 can be pressed into the inner bottom end of the ladder frame 101 under the weight of the ladder frame 101 itself, so that the moving mechanism 2 can be quickly stored as a whole into the inner bottom end of the ladder frame 101. After the moving mechanism 2 is retracted to the inner bottom end of the ladder frame 101, the fastening nut 206 can be tightened again.
