Firstly, an operator pulls the bracket 10 to rotate, the bracket 10 rotates to drive the slide rod 13 to rotate through the first support rod 11 and the second support rod 12, the slide rod 13 rotates to drive the second support plate 15 to rotate through the sliding sleeve 14, and then drives the first fixing plate 16 to rotate, when the first fixing plate 16 rotates to the rear side of the circular support plate 4, the bracket 10 stops being pulled, then the steel bar which is bundled into the shape of a circular well cover can be placed on the circular support plate 4, and the steel bar is moved to the lower side of the clamping part of the clamping device 5, then the steel bar is fixed through the clamping device 5, then the bracket 10 is rotated to the original position, the first cutting blade 20 and the second cutting blade 25 rotate to the upper side and the lower side of the steel bar, the bracket 10 is stopped being pulled, then the second support plate 15 is pulled to move left and right, the second support plate 15 moves left and right to drive the first fixing plate 16, when the first cutting blade 20 and the second cutting blade 25 move to the position for cutting the steel bars, the second support plate 15 is stopped to be pulled, the pressure rod 17 is pulled to swing downwards, the pressure rod 17 swings downwards to drive the roller 23 to move downwards, the roller 23 moves downwards to drive the first cutting blade 20 to move downwards through the second support 22, the second spring 21 is compressed, the first cutting blade 20 moves downwards to be contacted with the steel bars, the first cutting blade 20 is matched with the second blade to cut the steel bars, after the steel bars are cut, the pressure rod 17 is loosened, the first cutting blade 20 moves upwards to return to the original position under the action of the second spring 21, meanwhile, the pressure rod 17 also moves upwards to return to the original position, an operator rotates the circular support plate 4, the circular support plate 4 rotates to drive the steel bars which are tied into the circular well lid shape to rotate, and the next part of redundant steel bars rotates to a position between the first cutting blade 20 and the second cutting blade 25, and stopping rotating the circular supporting plate 4, pulling the pressure lever 17 to swing downwards again, and further enabling the first cutting blade 20 to move downwards to be matched with the second cutting blade 25 to cut off the steel bars, and repeating the operation so as to cut off all the redundant steel bars. After the redundant steel bars are completely cut off, the steel bars bundled into the shape of the circular well lid can be loosened through the clamping device 5, and then the steel bars bundled into the shape of the circular well lid are taken down.

Firstly, an operator puts a reinforcing steel bar which is bundled into a round well lid shape on a round supporting plate 4 and moves the reinforcing steel bar to the lower part of a fixed block 505, then shakes a left side poking rod 507 to rotate reversely and rotate the right side poking rod 507 to rotate forward, the left side poking rod 507 rotates reversely and drives a left side cam 508 to rotate reversely through a left side rotating shaft, the right side poking rod 507 rotates forward and drives a right side cam 508 to rotate forward through a right side rotating shaft, the left side cam 508 rotates reversely and the right side cam 508 rotates forward to contact with the round supporting plate 4, the cam 508 drives a first guide rod 502 to move downwards, a first spring 504 is compressed, the first guide rod 502 moves downwards and drives the fixed block 505 to move downwards, the fixed block 505 moves downwards and contacts with the reinforcing steel bar to be. Similarly, when the redundant steel bars are completely cut off, the left shifting rod 507 can be shaken to rotate forwards and the right shifting rod 507 rotates backwards, so that the cam 508 returns to the original position, and due to the action of the first spring 504, the first guide rod 502 moves upwards to drive the fixed block 505 to move upwards to loosen the steel bars bundled into the shape of the circular well lid, and an operator can take the steel bars down.

Firstly, an operator holds the bracket 10 to pull the handle 29 to move outwards, the third spring 28 is stretched, the handle 29 moves outwards to drive the second guide rod 27 to move outwards, the second guide rod 27 moves outwards to drive the first clamping block 31 to move outwards, the first clamping block 31 moves outwards to be separated from the first clamping groove 32 on the left side, the bracket 10 can be pulled to rotate to enable the first fixing plate 16 to move to the rear side of the circular supporting plate 4, then the handle 29 is loosened, due to the action of the third spring 28, the handle 29 moves inwards to drive the second guide rod 27 to move inwards, the second guide rod 27 moves inwards to drive the first clamping block 31 to move inwards to be clamped into the first clamping groove 32 on the rear side, the bracket 10 is fixed, and the operator can place the reinforcing steel bars which are pricked into the shape of the circular well cover on the circular supporting plate 4 to fix. After the reinforcing steel bars bundled into the shape of the circular well lid are fixed by the fixing block 505, the handle 29 can be pulled again to move outwards, so that the first clamping block 31 moves outwards to be separated from the first clamping groove 32 on the rear side, the bracket 10 is rotated again to return to the original position, the handle 29 is loosened, and the first clamping block 31 is clamped into the first clamping groove 32 on the left side to fix the bracket 10. Therefore, the support 10 can be prevented from freely swinging to influence the cutting of the first cutting blade 20 and the second cutting blade 25 on the redundant steel bars.

When the redundant steel bars move to a position between the first cutting blade 20 and the second cutting blade 25, the screw 34 can be twisted to move outwards, the screw 34 moves outwards to be separated from the second clamping groove 35, the second support plate 15 can be pulled to move left and right, the first cutting blade 20 and the second cutting blade 25 can move to the position where the redundant steel bars are cut, when the first cutting blade 20 and the second cutting blade 25 move to the position where the redundant steel bars are cut, the second support plate 15 stops being pulled, the twisted screw 34 moves inwards to be inserted into the second clamping groove 35, the twisted screw 34 is stopped, the screw 34 is matched with the second clamping groove 35 to fix the sliding sleeve 14, the second support plate 15 is fixed, and the cutting of the redundant steel bars can be started. Thus, the first cutting blade 20 and the second cutting blade 25 can be prevented from moving to affect the cutting accuracy.

When the first cutting blade 20 and the second cutting blade 25 cut off one of the redundant steel bars, an operator can step on the pedal 45 to move downwards, the pedal 45 moves downwards to drive the second clamping block 42 to move leftwards through the pulling rope 46, the fourth spring 41 is compressed, the second clamping block 42 moves leftwards to be separated from the third clamping groove 37, the circular supporting plate 4 can be rotated to drive the steel bars bundled into the shape of the circular well cover to rotate, when the next part of redundant steel bars rotate to a position between the first cutting position and the second cutting position, the circular supporting plate 4 stops rotating, the pedal 45 is released, the pulling rope 46 is loosened, and due to the action of the fourth spring 41, the second clamping block 42 moves rightwards to be clamped into the third clamping groove 37 to fix the rotary plate 36, and the circular supporting plate 4 is further fixed. So, can prevent to prick into the reinforcing bar of circular well lid shape and take place to remove the position that influences the truncation.
