[0036] When the wire moves to the cutting position, the heating frame 152 is started, and the heating frame 152 heats the electric cutter 5. When the electric cutter 5 is heated to the appropriate time, the heating frame 152 is turned off. When the electric cutter 5 needs to move downward to cut the wire, the stepper motor 153 is started to drive the front shaft 151 to rotate forward. The forward rotation of the front shaft 151 drives the rear shaft 151 to reverse through gear transmission. The reverse rotation of the rear shaft 151 and the forward rotation of the front shaft 151 drive the front and rear heating frames 152 to swing upward by ninety degrees. The stepper motor 153 is turned off, and the heating frame 152 stops covering the electric cutter 5, and the heated electric cutter 5 can be started to cut the wire. When the electric cutter 5 moves upward to reset, the stepper motor 153 is started to drive the front shaft 151 to reverse, so that the front and rear heating frames 152 swing downward to reset and cover the electric cutter 5. The heating frame 152 is started to continue to heat the electric cutter 5. When the wire cutting is completed, the heating frame 152 is turned off. In this way, the resistance during the cutting process can be reduced, so that the electric cutter 5 can cut the wire more easily.

[0037] When the rodless cylinder 12 drives the guide plate 121 to move backward, the clamping plate 122 drives the wire to move backward for traction, and the rodless cylinder 12 drives the pull wire 165 to move backward, the pull wire 165 drives the winding wheel 164 to reverse, the winding wheel 164 drives the rotating rod 162 to reverse, the coil spring 163 is compressed, the rotating rod 162 reverses and drives the bevel gear 166 to reverse, the bevel gear 166 reverses and drives the bevel gear ring 167 to rotate forward, the bevel gear ring 167 rotates forward and drives the annular brush 16 to rotate forward, and the annular brush 16 rotates forward to remove impurities attached to the wire. When the rodless cylinder 12 drives the guide plate 121 to move forward and reset, the rodless cylinder 12 causes the pull wire 165 to be loosened, and due to the action of the coil spring 163, the rotating rod 162 rotates forward and drives the winding wheel 164 to rotate forward, and the winding wheel 164 rotates forward to rewind the pull wire 165 and reset it. In this way, impurities attached to the wire can be prevented from affecting subsequent use, thereby ensuring the subsequent normal use of the wire.

[0038] See also Fig.11 As shown, the wire cutting device for power construction also includes a limiting ball 18 and a connecting spring 19. The connecting spring 19 is symmetrically connected to the upper and lower sides of the right side of the placement roller 3. The tail ends of the connecting springs 19 on the upper and lower sides are fixedly connected to the limiting ball 18. The limiting ball 18 is slidably connected to the placement roller 3. When a roll of wire is put on the placement roller 3, the limiting ball 18 can limit the winding drum of the wound wire.

[0039] When the winding drum with the wire wound is placed on the placement roller 3, the limiting ball 18 contacts the winding drum, and then when the wire is pulled backward for transportation, the limiting ball 18 can limit the winding drum due to the action of the connecting spring 19. After the wire cutting is completed, the winding drum is pulled forward to contact the limiting ball 18, and the winding drum drives the limiting balls 18 on the upper and lower sides to move towards each other, and the connecting spring 19 is compressed. When the winding drum is removed, the winding drum is disengaged from the limiting ball 18, and the limiting ball 18 moves and resets due to the action of the connecting spring 19. In this way, the winding drum can be prevented from falling off the placement roller 3 to affect the transportation and cutting of the wire, thereby ensuring smooth electric cutting.
