The invention is moved to a required position, then the large base 1 is pressed downwards, the left large arc-shaped slotting tool 4, the right large arc-shaped slotting tool 8 and the conical ring cutter 12 are inserted into the ground downwards, simultaneously the large inserted bar 2 is inserted into the ground, then the large inserted bar 2 is pressed downwards, the large inserted bar 2 drives the semicircular plate 3 to move downwards, the semicircular plate 3 drives the first large connecting rod 7 and the second large connecting rod 11 to move outwards, simultaneously the first large connecting rod 7 and the second large connecting rod 11 respectively drive the first clamping tool 6 and the second clamping tool 10 to move outwards, so that the first clamping tool 6 and the second clamping tool 10 firmly clamp the ground, thereby fixing the invention, simultaneously the large inserted bar 2 drives the left fixing plate 13 and the right fixing plate 18 to move downwards, and respectively clamp the left triangular clamping block 15 and the right triangular clamping block 20 through the left clamping plate 16 and the right clamping plate 21, the first plate spring 17 can enable the left triangular clamping block 15 to be in contact with the left clamping plate 16, meanwhile, the second plate spring 22 can enable the right triangular clamping block 20 to be in contact with the right clamping plate 21, so that the large insertion rod 2 can be fixed, then people can insert the lower end of the greenhouse arch bar into the large insertion hole 201, then people can screw the large screw 27, the large screw 27 drives the right pressing block 26 to move leftwards, meanwhile, the rectangular frame 24 drives the left pressing block 25 to move rightwards, and the left pressing block 25 and the right pressing block 26 clamp the greenhouse arch bar firmly together, so that the fixing is convenient and rapid.
People can promote left L shape push rod 32 and right L shape push rod 35 inboard respectively this moment, left L shape push rod 32 and right L shape push rod 35 can promote left little connecting rod 14 and the little connecting rod 19 inboard of right side respectively, thereby be convenient for with left triangle fixture block 15 and left cardboard 16, and right triangle fixture block 20 and right cardboard 21 separate, and convenient for operation, and left L shape push rod 32 and right L shape push rod 35 can block respectively on left L shape limiting plate 33 and right L shape limiting plate 36, it carries out other operations to be convenient for people to vacate the hand, and the strength is saved.
After big inserted bar 2 inserts a certain position in the soil downwards, people can hang couple 42 in pull ring 43 to carry out better fixed to big inserted bar 2, thereby through redundant fixed measure, provide better fixed for the big-arch shelter arch bar.
