[0046] The support assembly 2 is provided with three, which are uniformly arranged in a circumferential array on the bottom surface of the mounting plate 1. Specifically, the support assembly 2 comprises an outer sleeve rod 201 fixedly installed on the bottom surface of the mounting plate 1 by bolts and an inner sleeve rod 202 movably arranged in the outer sleeve rod 201. The inner part of the outer sleeve rod 201 is concave to form a moving groove 207, which penetrates to the top of the outer sleeve rod 201. The top of the inner sleeve rod 202 forms an anti-drop block 208 corresponding to the moving groove 207. The inner sleeve rod 202 can be inserted into the inner sleeve rod 202 from the top of the outer sleeve rod 201. When the top of the inner sleeve rod 202 moves to the bottom of the outer sleeve rod 201, the anti-drop block 208 can abut against the bottom of the moving groove 207 to prevent the inner sleeve rod 202 from falling out of the outer sleeve rod 201. At the same time, the arrangement of the moving groove 207 and the anti-drop block 208 can avoid the rotation of the inner sleeve rod 202 relative to the outer sleeve rod 201, thereby improving the stability of the inner sleeve rod 202;

[0047] The bottom end of the outer sleeve rod 201 forms an annular mounting platform 210. A first limiting collar 203, coaxially arranged with the inner sleeve rod 202, is fixedly mounted on the 210 by screws. The bottom of the first limiting collar 203 forms a plurality of first abutting petals 204. The first abutting petals 204 are deformable. Specifically, the first abutting petals 204 are made of deformable PP material. The inner sleeve rod 202 is movably arranged inside the first limiting collar 203. A first tightening collar 205 is movably sleeved outside the first limiting collar 203. The inner wall of the first tightening collar 205 forms a frustum-shaped first abutting surface 206.

[0050] Specifically, the drive assembly 4 includes a connecting plate 401 movably mounted on the central vertical rod 3 and a second limiting collar 402 fixedly mounted below the connecting plate 401. The second limiting collar 402 has multiple second abutment flaps 403 formed on it. The second abutment flaps 403 are deformable. Specifically, the second limiting collar 402 is made of deformable PP material. A second tightening collar 404 is movably fitted onto the second limiting collar 402. The inner wall of the second tightening collar 404 forms a frustum-shaped second abutment surface 405. Specifically, the outer wall of the second limiting collar 402 has an external thread, and the inner wall of the second tightening collar 404 has an internal thread. The second limiting collar 402 and the second tightening collar 404 are threaded together. The connecting plate 401 is connected by a threaded joint. After rotating the second abutment sleeve, the second abutment surface 405 can press the second abutment petal 403 against the central vertical rod 3, thereby fixing the position of the connecting plate 401. The connecting plate 401 is hinged to the three first abutment rings 205 through the hinge rod 406. When the connecting plate 401 is moved upward, since the outer rod 201 is fixed, the hinge rod 406 will drive the first abutment rings 205 to move until the first abutment rings 205 press the first abutment petal 204 against the inner rod 202. Then, the second abutment ring 404 is rotated until the second abutment petal 403 is pressed against the central vertical rod 3.

[0052] Further, the fixed plate 301 is fixedly installed on the vertical rod 3, and the fixed plate 301 is connected with the connecting plate 401 through the reset spring 302, and the reset spring 302 is sleeved outside the vertical rod 3, by arranging the reset spring 302, after the second abutting ring 404 is unscrewed to release the limiting of the connecting plate 401, the reset spring 302 can automatically push the connecting plate 401 to move downward to release the limiting of the three inner sleeve rods 202;

[0053] The reset spring 302 is sleeved with the telescopic rubber sleeve 303, and the two ends of the telescopic rubber sleeve 303 are sealingly connected with the fixed plate 301 and the connecting plate 401 respectively, since the fixed support is usually used outdoors, the telescopic rubber sleeve 303 can protect the reset spring 302 from rusting, and also can prevent the reset spring 302 from being clamped to the hands of the worker after being compressed.

[0054] Further, in order to improve the stability of the connecting plate 401, the limiting rod 304 is fixedly arranged on the fixed plate 301, the limiting groove 305 corresponding to the limiting rod 304 is formed on the connecting plate 401, the limiting rod 304 is inserted into the limiting groove 305, and the limiting stop plate 306 is fixedly arranged at the bottom end of the limiting plate, the limiting rod 304 can prevent the connecting plate 401 from rotating to improve the stability of the connecting plate 401, and the limiting stop plate 306 can limit the lowest moving position of the connecting plate 401.

[0055] Further, the stepping plate 209 is fixedly installed on the inner sleeve rod 202 close to the bottom, so that the worker can move the inner sleeve rod 202 by stepping with the feet.

[0056] Further, the telescopic inner rod 307 is movably arranged in the vertical rod 3, the third limiting ring 308 coaxially arranged with the telescopic inner rod 307 is fixedly installed at the bottom end of the vertical rod 3, the third limiting ring 308 forms a plurality of third abutting petals 309, the third abutting petals 309 are deformable, specifically, the third abutting petals 309 are made of deformable PP material, the third abutting ring 308 movably sleeves the third abutting ring 310, the inner wall of the third abutting ring 310 forms a circular truncated third abutting surface 311, specifically, the outer wall of the third limiting ring 308 forms an external thread, the inner wall of the third abutting ring 310 forms an internal thread, and the third limiting ring 308 and the third abutting ring 310 are threadedly connected.

[0057] When using the fixing support, first rotate the third abutting ring 310 to release the third limiting ring 308 from limiting the telescopic inner rod 307, then extend the telescopic inner rod 307 to a suitable length, and finally tighten the third abutting ring 310 to fix the telescopic inner rod 307;

[0058] Take the bottom end of the telescopic inner rod 307 as a fulcrum, stand the fixing support on the ground, and support the fixing support to a substantially horizontal position;

[0059] Rotate the second abutting ring 404 to release the limiting of the connecting plate 401, and the reset spring 302 automatically drives the connecting plate 401 to move, which drives the first abutting ring 205 to release the limiting of the inner sleeve rod 202, and the inner sleeve rod 202 automatically falls to the position abutting against the bottom surface under the action of gravity;

[0060] The staff presses the pressing plate 209 downward with the foot, so that the inner sleeve rod 202 abuts against the bottom surface;

[0061] The staff manually pushes the connecting plate 401 upward to limit the inner sleeve rod 202, and then tightens the second abutting ring 404 to fix the position of the connecting plate 401.
