[0035] Please refer to Figures 1-8 On the basis of the above embodiment, the anti-loosening device 12 is further included in another embodiment of the present application.

[0036] The anti-loosening device 12 includes a friction wheel 121, the friction wheel 121 is rotatably installed in the T-shaped leg 11 near one side of the irrigation mechanism 6, a screw rod 122 is fixedly installed on one side of the friction wheel 121 near the irrigation mechanism 6, the screw groove on the outer wall of the screw rod 122 is a non-self-locking screw groove, a limiting rod 123 is fixedly installed on one side of the T-shaped leg 11 near the screw rod 122, a Z-shaped plate 124 is movably installed through the outer wall of the screw rod 122, and an antiskid rubber pad 125 is fixedly installed on one side of the Z-shaped plate 124 below and near the irrigation mechanism 6.

[0037] The outer wall of the T-shaped leg 11 is in contact with the inner wall of the support frame 10, the outer wall of the friction wheel 121 has strong friction, and is in a non-slip state when in contact with the inner wall of the support frame 10, the Z-shaped plate 124 is internally and slidingly installed on the outer wall of the limiting rod 123, and the limiting rod 123 limits the horizontal movement of the Z-shaped plate 124, and the anti-skid rubber pad 125 is in contact with the outer wall of the irrigation mechanism 6 after the installation of the irrigation mechanism 6 and the spiral mechanism 5 is completed.

[0038] The top of the Z-shaped plate 124 is fixedly installed with an arc clamping column 126 near one side of the irrigation mechanism 6, the top edge of the irrigation mechanism 6 is fixedly installed with a U-shaped clamping plate 127, a plurality of limiting blocks 128 are symmetrically and slidingly installed in the U-shaped clamping plate 127 through springs, the top arc of the limiting block 128 is larger than the bottom, and the outer wall of the arc clamping column 126 is in contact with the top arc of the limiting block 128.

[0039] The anti-skid rubber pad 125 is slidingly connected to the irrigation mechanism 6 to ensure that the top of the irrigation mechanism 6 and the spiral mechanism 5 are always in a stable connection state when the body 1 flies up and down or turns, prevents the connection strength of the two from being reduced due to frequent changes in force, and avoids the possibility of increasing looseness caused by wear and tear of the connection end of the two; the limiting block 128 limits and blocks the arc clamping column 126, so that when the T-shaped leg 11 is impacted and disturbed by external objects during the flight of the body 1, the T-shaped leg 11 is limited by the limiting block 128, the movement amplitude of the T-shaped leg 11 is reduced, the limiting of the anti-skid rubber pad 125 to the irrigation mechanism 6 is avoided, further wear and tear between the irrigation mechanism 6 and the spiral mechanism 5 is avoided, and the safety of the equipment is improved.

[0045] A circular rod 137 is slidably installed in the sliding groove of the arc-shaped tough plate 135 through a spring, the circular rod 137 provides a force for sliding and resetting, a rubber roller 138 is rotatably installed on the outer wall of the circular rod 137, and the outer wall of the rubber roller 138 is in contact with the outer wall of the T-shaped leg 11 and the support frame 10 adjacent to the included angle after the body 1 ascends.

[0046] Through the support outer plate 136 overturns and the data transmission of the inductor, the worker can know that the equipment is normal operation, and when the machine body 1 lands, under the action of gravity, the T-shaped foot 11 resets, and the above structure resets synchronously, and the support outer plate 136 and the support inner plate 134 reset, the contact area of the bottom of the T-shaped foot 11 and the ground is expanded, and the support stability of the T-shaped foot 11 on the uneven ground is enhanced; through the close contact of the rubber roller 138 to the outer wall of the T-shaped foot 11, the T-shaped foot 11 always slides in the same direction when resetting after the machine body 1 rises, avoiding the loosening phenomenon of the T-shaped foot 11 in the long-term sliding process, reducing the smoothness of the T-shaped foot 11 in the sliding process in the support frame 10, increasing the wear of the outer wall of the T-shaped foot 11, thereby affecting the extension and resetting process.

[0047] When in use, the Z-shaped plate 124 pulls the gusset plate 133 to move synchronously, and the support frame 10 limits the fixed plate 131, and the fixed plate 131 limits the horizontal rod 132, under the limitation of the horizontal rod 132 and the pulling of the Z-shaped plate 124, the gusset plate 133 generates a rotating force and starts to rotate along the outer wall of the horizontal rod 132, at this time, the hinge shaft of the gusset plate 133 starts to rotate and pulls the support inner plate 134 to move synchronously, the support inner plate 134 starts to overturn with the hinge shaft between itself and the T-shaped foot 11 as the axis, the hinge shaft of the arc-shaped tough plate 135 starts to rotate when the support inner plate 134 overturns, the arc-shaped tough plate 135 is pushed by the support inner plate 134 and limited in the support frame 10, so that the other end of the arc-shaped tough plate 135 pushes the support outer plate 136 to overturn downward with the hinge shaft as the center, and the support outer plate 136 transmits the overturning data of itself through the built-in inductor; the arc-shaped tough plate 135 drives the circular rod 137 to move synchronously when sliding in the support frame 10, the circular rod 137 drives the rubber roller 138 to move towards the sliding connection between the T-shaped foot 11 and the support frame 10, when the rubber roller 138 contacts the outer wall of the T-shaped foot 11, a resisting force is generated, at this time, the circular rod 137 drives the rubber roller 138 to start to slide along the sliding groove of the arc-shaped tough plate 135, with the help of the elastic force of the spring, the outer wall of the rubber roller 138 is always tightly attached to the outer wall of the T-shaped foot 11 to rub, at this time, the rubber roller 138 starts to rotate along the outer wall of the circular rod 137 through the friction force.

[0048] According to the above embodiment, the data transmission of the support outer plate 136 is flipped over and inducted, so that the worker can know that the equipment is in normal operation. When the machine body 1 lands, the T-shaped supporting leg 11 is reset under the action of gravity, and the above structure is reset synchronously. The support outer plate 136 and the support inner plate 134 are reset, the contact area of the bottom of the T-shaped supporting leg 11 and the ground is expanded, and the supporting stability of the T-shaped supporting leg 11 on the uneven ground is enhanced. The rubber roller 138 is in close contact with the outer wall of the T-shaped supporting leg 11, so that the T-shaped supporting leg 11 always slides in the same direction when it is reset after the machine body 1 is lifted. The loosening phenomenon of the T-shaped supporting leg 11 in the long-term sliding process is avoided, the smoothness of the T-shaped supporting leg 11 in the sliding process in the support frame 10 is reduced, the abrasion of the outer wall of the T-shaped supporting leg 11 is increased, and thus the extension and reset process of the T-shaped supporting leg 11 is affected.

[0049] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
