[0039] The working principle of this embodiment: Figure 2-3 and Figure 8 When using the adjustable folding house installation protection device, the staff first moves the device to the side of the folding house that needs to be opened, rotates the adjusting screw rod 12 around the connecting shaft 133, and at the same time, the limiting rod 151 rotates on the outside of the lifting box 8. The adjusting screw rod 12 and the limiting rod 151 are parallel to the rotating sleeve shaft 11 at the same time. The adjusting screw rod 12 is used to drive the connecting shaft 133 to move inside the through groove 19, and the connecting shaft 133 moves outside the fixed shaft 131, and at the same time drives the reset spring 132, so that one end of the adjusting screw rod 12 is engaged in the through groove 19, and due to the force of the reset spring 132, the adjusting screw rod 12 will not slide to the outside of the through groove 19, so that its connection is stable, so that the connecting block 14 on the adjusting screw rod 12 drives the connected and installed support mechanism 16 to move downward;

[0040] according to Figure 1-3 and Figure 5-7, the staff installs the top of the folding house and hoists it, and the folding house is opened by the crane. After the folding house is partially opened, the support plate 161 is placed on the edge of the folding house, so that the support plate 161 is engaged with the wall of the folding house, and the support plate 161 rotates around the connecting rod 163 at the inclined angle of the folding house wall, so that the support plate 161 fits the wall of the folding house, and the limit block 164 and the card block 166 limit the reverse rotation of the support plate 161, and the drive motor 5 is turned on to drive the connected drive shaft 6 to rotate, and the drive shaft 6 drives the drive bevel gear 4 to rotate, so that the drive bevel gear 4 drives the driven bevel gear 3 to rotate The driven bevel gear 3 drives the lifting screw 2 connected and installed above it to rotate, so that the lifting box 8 rises on the outside of the lifting screw 2. At the same time, the driven bevel gear 3 on the other side drives the linkage rod 91 connected and installed above it to rotate, so that the linkage rod 91 drives the linkage sleeve shaft 93 to rotate inside the movable groove 95 through the engagement of the protrusion 92 and the groove 94. When the linkage sleeve shaft 93 rotates, it drives the worm wheel 17 fixedly installed outside it to rotate, so that the worm wheel 17 drives the worm 10 meshing with it to rotate, so that the worm 10 drives the rotating sleeve shaft 11 connected and installed at both ends to rotate, thereby driving the adjusting screw 12 inside the rotating sleeve shaft 11 to rotate;

[0041] according to Figure 2-4 When the adjusting screw rod 12 rotates, the connecting block 14 moves on the adjusting screw rod 12, and at the same time, the movable block 153 connected and installed on one side of the connecting block 14 slides in the limiting groove 152 inside the limiting rod 151. When the crane drives the folding house to open, the supporting plate 161 opens to the left and right sides accordingly, and as the angle of the folding house wall changes, the supporting sleeve shaft 162 at the bottom of the supporting plate 161 rotates outside the connecting rod 163, so that the supporting plate 161 always fits the wall of the folding house and supports the wall of the folding house. After use, the driving motor 5 rotates in the opposite direction to lower the lifting box 8, and the supporting plate 161 moves closer to the middle, holding The screw rod 12 is adjusted and pulled outwardly toward the through slot 19, so that the connecting shaft 133 on the screw rod 12 moves toward the slot 18 and squeezes the return spring 132. After the tail end of the screw rod 12 moves to the slot 18, the screw rod 12 is rotated to engage with the slot 18 and be parallel to the lifting screw rod 2. The knob 134 is rotated to engage with the slot 135 to limit the adjusting screw rod 12 and complete the storage. This device can be placed at both ends of the folding house to avoid the wall of the folding house falling due to the instability of the crane, and to avoid damage to the house or safety hazards to surrounding workers, thereby completing a series of tasks.
