A plurality of support rods 32 are fixedly connected inside the cleaning groove 31 at the bottom end of the cross rod 4, a plurality of ball heads 33 are found on the top surface of the support rods 32 in a rotating mode, a flat plate 34 is fixedly connected to the top end of each ball head 33, a plurality of cleaning needles 35 are fixedly connected to the top end of each flat plate 34, a plurality of convex teeth are fixedly connected to the outer ring of each cleaning needle 35, the cleaning needles 35 and the convex teeth are in sliding fit with latticed grooves of the grinding balls 17, a second spring 36 is fixedly connected to the bottom surface of each flat plate 34, the bottom end of each second spring 36 is fixedly connected to the top surface of the support rod 32, and the second spring 36 is sleeved on the outer ring of each ball head 33; when the thread sleeve seat 16 is moved to the cleaning groove 31 in a rotating mode, the latticed groove of the polishing ball 17 is in sliding fit with the needle points and the convex teeth of the cleaning needle 35, iron rust in the latticed groove of the polishing ball 17 is removed, the second spring 36 is matched with the ball head rod 33, when the polishing ball 17 is in sliding fit with the cleaning needle 35, the ball head rod 33 is rotated, the cleaning needle 35 is attached to the polishing ball 17 more tightly, and after the thread sleeve seat 16 is moved out of the cleaning groove 31, the second spring 36 is reset, the cleaning needle 35 is reset, and therefore the polishing effect of the polishing ball 17 is improved; meanwhile, when the threaded sleeve seat 16 rotationally moves to the cleaning groove 31, a worker uses an injection needle to penetrate through the cleaning groove 31 to add lubricating oil into the oil cavity 23, so that the worker can add the lubricating oil in time.

A plurality of accommodating grooves 37 are formed in the inner ring of one end, far away from the upright post 1, of the cross rod 4, a dirt removing knife 38 is rotatably mounted inside each accommodating groove 37, an arc-shaped round hole 39 is formed in the outer ring of each accommodating groove 37, an arc-shaped push rod 40 is slidably mounted inside each arc-shaped round hole 39, the bottom end of each arc-shaped push rod 40 is fixedly connected with the dirt removing knife 38, a third spring 41 is arranged inside each arc-shaped round hole 39, a plurality of oblique tooth grooves are formed in the inner ring of each dirt removing knife 38, and the inner ring of each dirt removing knife 38 is in sliding fit with the cross rod insertion tube 5; during the use, No. three spring 41 promote arc push rod 40 and slide to accomodating the inslot 37 along arc round hole 39, promote the sword 38 of decontaminating and hug closely horizontal pole intubate 5 for when horizontal pole intubate 5 inserts horizontal pole 4 inside, the sand and stone etc. that are stained with on the surface of horizontal pole intubate 5 are blockked by the clearance of sword 38 of decontaminating, have avoided in sand and stone along with horizontal pole intubate 5 entering horizontal pole 4, cause the slip of horizontal pole 4 to block, thereby further improved the slip smoothness nature between horizontal pole intubate 5 and the horizontal pole 4.

Example two

As shown in fig. 9, a connecting disc 42 is fixedly connected to the bottom end of the upright post 1, and the connecting disc 42 is fixedly connected to the disc buckle 2 through a bolt 7; through using bolt 7 to detain 2 rigid couplings with connection pad 42 and dish, the staff of being convenient for installs a plurality of stands 1, has improved the convenience of staff's installation.

The working principle is as follows: during installation, the upright post 1 is fixed to the outer side of a building, the buckle joint 3 is fixedly connected with the disc buckle 2 by using the bolt 7, the cross rod inserting tube 5 is drawn out from the cross rod 4, so that the limiting iron plate 6 contacts the wall of the building, the top end of the first inclined rod 8 is fixedly connected with the bottom end of the cross rod 4 through a bolt, the arc-shaped iron plate 9 at the bottom end of the first inclined rod 8 is clamped on the outer side of the upright post 1, the arc-shaped iron plate 9 is locked by using the bolt, the vertical rod 10 is connected with the first inclined rod 8 and the cross rod 4 through the bolt, then the thumb bolt 14 is screwed, the cross rod inserting tube 5 is fixedly locked with the cross rod 4, the pipe sleeve 11 is fixed on the outer side of the cross rod inserting tube 5, and the second inclined rod 12 is connected with the residual arc-shaped iron plate 9 of the pipe sleeve 11 by using the bolt; when the distance between the tripod and the building needs to be adjusted, the thumb bolt 14 is loosened, then the bolt of the second inclined rod 12 is loosened, the cross rod insertion tube 5 is pushed to slide along the inside of the cross rod 4, and after the distance between the tripod and the building is adjusted, the thumb bolt 14 and the bolt of the second inclined rod 12 are tightened; the distance between the tripod and the building is adjusted, the repeated disassembly and assembly of the tripod by workers are avoided, the workload of the workers is reduced, the working efficiency is improved, and the labor cost is reduced;

during recovery, the thumb bolt 14 is unscrewed, the bolts of the first inclined rod 8, the second inclined rod 12 and the vertical rod 10 are dismounted, and the first inclined rod 8, the second inclined rod 12 and the vertical rod 10 are dismounted; the cross rod insertion tube 5 is pushed to slide into the cross rod 4 to drive the threaded sleeve seat 16 to rotate and slide along the screw rod 15, the sliding column 20 is pushed to slide upwards along the circular groove 18 by the elasticity of the first spring 21, the grinding ball 17 is always attached to the inner wall of the cross rod 4, and the grinding ball 17 polishes and derusts the inner wall of the cross rod 4; meanwhile, when the threaded sleeve base 16 rotates, lubricating oil extrudes the rubber elastic sheet 29 and the lug 30 under the action of centrifugal force, the rubber elastic sheet 29 and the lug 30 rotate towards two sides to expose gaps, the lubricating oil enters the annular groove 25, the lubricating oil wets the sponge ring 27, the surface of the brush 28 adsorbs the lubricating oil, the brush 28 is in sliding fit with the inner wall of the cross rod 4, and the lubricating oil is smeared on the inner wall of the cross rod 4; meanwhile, the third spring 41 pushes the arc-shaped push rod 40 to slide towards the accommodating groove 37 along the arc-shaped round hole 39, and pushes the dirt removing knife 38 to cling to the cross rod insertion tube 5, so that when the cross rod insertion tube 5 is inserted into the cross rod 4, sand and stones on the surface of the cross rod insertion tube 5 are removed and blocked by the dirt removing knife 38, and the sand and stones are prevented from entering the cross rod 4 along with the cross rod insertion tube 5; when the threaded sleeve seat 16 rotates and moves to the cleaning groove 31, the latticed groove of the polishing ball 17 is in sliding fit with the needle point and the convex tooth of the cleaning needle 35, rust dust in the latticed groove of the polishing ball 17 is removed, the second spring 36 is matched with the ball head rod 33, and when the polishing ball 17 is in sliding fit with the cleaning needle 35, the ball head rod 33 rotates, so that the cleaning needle 35 is attached to the polishing ball 17 more tightly, and the polishing effect of the polishing ball 17 is improved; the rust of 4 inner walls of horizontal pole is polished through the ball of polishing, and the needle point and the protruding tooth of clearance needle 35 clear up the recess on ball surface of polishing, and lubricating oil lubricates 4 inner walls of horizontal pole to and the sword 38 of decontaminating clears up the surperficial gravel and sand of horizontal pole intubate 5, improved the smooth nature of sliding between horizontal pole intubate 5 and the horizontal pole 4, reduced the degree of difficulty that the staff retrieved the tripod.
