[0022] The stabilizing mechanism 2 includes a stabilizing plate 201, a knob 202 and a pressure plate 203, and the stabilizing plate 201 is fixedly mounted on the upper surface end of the base 1, and the inner wall of the end of the stabilizing plate 201 is provided with a knob 202, and the lower end of the knob 202 is movably mounted with a pressure plate 203, so as to ensure the stability of the device during use through the stabilizing mechanism 2.

[0023] The stabilizing plate 201 is symmetrically distributed about the longitudinal center axis of the base 1, and the knob 202 is symmetrically arranged about the longitudinal center axis of the stabilizing plate 201, so as to increase the supporting area of ​​the device and ensure the stability of the device.

[0024] The stabilizing plate 201 and the knob 202 are threadedly connected, and the knob 202 and the pressure plate 203 form a rotating structure, which is convenient for the user to rotate the knob 202 so that the knob 202 moves downward relative to the stabilizing plate 201, thereby driving the pressure plate 203 to fit the ground, thereby increasing the support area of ​​the device.

[0025] The transmission rod 6 and the support rod 7 are threadedly arranged, and the clamping arm 9 and the clamping plate 4 form a sliding structure, which makes it convenient for the servo motor 3 to drive the transmission rod 6 to rotate, so that the support rod 7 moves vertically along the transmission rod 6, thereby adjusting the height of the device, and as the support rod 7 moves, the support rod 7 drives the clamping arm 9 to slide relative to the clamping plate 4, so that the support rod 7 can stably move in the vertical direction.

[0026] The inner wall of the positioning plate 10 is movably connected to the limit bolt 12, and the limit bolt 12 is threadedly connected to the card hole 5, the positioning plate 10 and the limit plate 11 respectively, so that after the height adjustment of the device is completed, the user rotates the limit bolt 12 so that the limit bolt 12 moves relative to the positioning plate 10, passes through the card hole 5 and is inserted into the limit plate 11, thereby supporting the support rod 7 and enhancing the supporting stability of the support rod 7.

[0027] Working principle: When using the fixed support of the crane, first Figure 1-3 As shown, the user moves the device to the working position, at which time the base 1 is in contact with the ground, and then the user rotates the knob 202, and then the knob 202 moves downward relative to the stabilizing plate 201, and then the knob 202 drives the pressure plate 203 to move downward in contact with the ground, and similarly operates the remaining knobs 202, thereby completing the positioning of the device, and then the user adjusts the height of the device according to needs, such as Figure 1 and Figure 3-4 As shown, at this time, the user starts the servo motor 3, and then the servo motor 3 drives the transmission rod 6 to rotate, and then the support rod 7 moves vertically along the transmission rod 6, and as the support rod 7 moves, the support rod 7 drives the clamping arm 9 to slide relative to the clamping plate 4. When the height adjustment of the support rod 7 is completed, the user rotates the limit bolt 12, and then the limit bolt 12 moves relative to the positioning plate 10, and then the limit bolt 12 passes through the clamping hole 5 and is inserted into the limit plate 11. The remaining limit bolts 12 are operated in the same way, thereby completing the height adjustment of the device. Next, the user installs the crane truss on the mounting plate 8, so that the device can easily allow the crane truss to be installed on mounting plates 8 of different heights, thereby completing the height adjustment of the crane truss, which is convenient for the device to adapt to different environments for use.
