Embodiment 2, on the basis of embodiment 1, as shown in fig. 1 and 8, an auxiliary structure 8 is disposed on a side wall of a frame 4, the auxiliary structure 8 includes two fixing plates 801, a surface of the fixing plate 801 is fixedly connected with the frame 4, the two fixing plates 801 are two in number, one ends of the two fixing plates 801 close to each other are rotatably connected with a rotating plate 803, a limiting rod 802 is slidably inserted inside the rotating plate 803, one end of the limiting rod 802 far from the rotating plate 803 is fixedly connected with a long plate 807, a surface of the long plate 807 is fixedly connected with a limiting block 806, one end of the limiting block 806 far from the long plate 807 is fixedly connected with a connecting rod 805, a position of the rotating plate 803 relative to the connecting rod 805 is fixedly connected with a rectangular block 804, the connecting rod 805 passes through the inside of the rectangular block 804, after a copper pipe is cut, the screw 5 is first screwed to make the screw 5 far from the copper pipe, at this time, the copper pipe is separated from a clamped state, at this time, by sliding the connecting rod 805, connecting rod 805 will drive long board 807 through stopper 806 and remove, thereby make long board 807 be close to the copper pipe, rotate this moment and change board 803, change board 803 will drive long board 807 through gag lever post 802 and rotate, because the copper pipe has some to stretch out from support column 62 after being cut, at this moment long board 807 will beat the one end that the copper pipe stretches out, thereby the copper pipe will be hit after hitting and fly to fall into in the box 812, base 1's lateral wall fixedly connected with pivot 810, the surface of pivot 810 rotates and is connected with and changes strip 808, the fixed surface of changing strip 808 is connected with footboard 809, base 1's surface rotates and is connected with box 812, the lateral wall fixedly connected with sand grip 811 of box 812, the bottom hole has been seted up to the one end that box 812 is close to fixed plate 801, the bottom fixedly connected with sack of box 812, change the surface and the sand grip 811 swing joint of strip 808.

The effect that its whole auxiliary structure 8 reaches is, through setting up auxiliary structure 8, after the copper pipe is cut, twist screw 5 first and make screw 5 keep away from the copper pipe, the copper pipe will break away from the state of being held at this moment, at this moment through sliding connecting rod 805, connecting rod 805 will drive long board 807 to move through stopper 806, thus make long board 807 close to the copper pipe, rotate and turn board 803 at this moment, turn board 803 will drive long board 807 to rotate through stopper 802, because there is a part that stretches out from support column 62 after the copper pipe is cut, at this moment long board 807 will beat the one end that the copper pipe stretches out, the copper pipe will be hit and fly and fall into box 812 after being hit, the workman is first sheathe gunny bag and fixed with the bolt at the bottom of box 812, at this moment the workman steps down footboard 809, footboard 809 will drive and turn the rotation of strip 808 through pivot 810, at this moment turn the strip 808 will lift box 812 through sand grip 811, box 812 will rotate through base 1 at this moment, and the bottom hole has been seted up to the one end bottom that box 812 is close to base 1, and the abandonment copper pipe in box 812 will pass through the bottom hole landing in the sack this moment to make things convenient for the workman to collect, whole structure has solved the workman when collecting the copper pipe of abandonment on support column 62, often need stretch out the hand and take on support column 62, and because cutting blade 10 is near frame 4, thereby the workman is if distracted easily by the problem that cutting blade 10 scratch influences follow-up work.
