[0033] As a technical solution of the present invention, a square opening is opened at one half of the inner tube of the electric telescopic rod 41 near one end of the hydraulic rod 3;

[0034] The size of the storage groove 42 is the same as that of the cutter 34 , and a ratchet 2 421 is fixedly connected to the upper third of the inner wall of one end of the storage groove 42 close to the hydraulic rod 3 .

[0035] As a technical solution of the present invention, the detection mechanism 5 includes a turntable 51, a connecting rod 52 and a gear 53. The turntable 51 is rotatably connected to one side of the fuselage 1 and is located on one side of the square hole 11. One side of the center of the turntable 51 is rotatably connected to the connecting rod 52. A slide groove 54 is provided on the connecting rod 52. A rotating rod 56 and a fixed rod 57 are rotatably connected in the slide groove 54. The fixed rod 57 is located on one side of the rotating rod 56. A controller 55 is provided at one end of the slide groove 54 away from the rotating rod 56. One end of the rotating rod 56 away from the sliding groove 54 is connected to the fixed rod 57, and a side of the fixed rod 57 away from the rotating rod 56 is slidably connected with a ball 58, and a small part of the side of the ball 58 away from the fixed rod 57 is embedded in the cutter 34. One end of the connecting rod 52 away from the turntable 51 is rotatably connected to the center of the gear 53, and the gear 53 is connected to the fuselage 1. A track is provided at the connection between the gear 53 and the fuselage 1, and a fixing block three 59 is connected to the bottom of the gear 53.

[0036] As a technical solution of the present invention, the bottom plate of the chute 54 facing the cutter 34 is a semicircle with the same size as the ball 58;

[0037] A plurality of square grooves 591 are provided in the fixing block 59 . The size of the square grooves 591 is larger than the size of the teeth on the gear 53 , but the spacing between each square groove 591 is smaller than the spacing between each tooth on the gear 53 .

[0038] Working principle:

[0039] First, if Figure 1-2 and Figure 4-5 As shown, the staff adjusts the distance between the fixed block 2 32 and the limit block 33 by turning the bolt 321 according to the size of the metal wire passing through, and then according to the hardness of the metal wire and the required truncation length (if the hardness of the metal wire is harder and the truncation length is longer, the slope of the connecting rod 52 is slowed down, otherwise the slope of the connecting rod 52 is steepened), the staff turns the turntable 51 to adjust the slope of the connecting rod 52, one end of the connecting rod 52 rotates with the turntable 51, and the other end of the connecting rod 52 drives the gear 53 to slide on the fixed block 3 59 synchronously. At this time, the rotating shaft on the gear 53 is located as shown in FIG. Figure 3The upper half of the track in the middle, so the teeth on the gear 53 will not be stuck in the second square groove 591 during the rolling process. When the slope of the connecting rod 52 is adjusted to a suitable level, the staff pulls the gear 53 outward and then inserts the rotating shaft of the gear 53 into the lower half of the track, so that the teeth on the gear 53 are stuck in the second square groove 591 and cannot continue to rotate, thereby fixing the connecting rod 52 and the turntable 51; when the connecting rod 52 moves, the rotating rod 56 and the fixed rod 57 follow the movement of the connecting rod 52. The rotating rod 56 is in an inclined state at this time, and its end is against the fixed rod 57, supporting the fixed rod 57; when the staff starts the hydraulic rod 3, the hydraulic rod 3 presses the cutter 34 downward to cut the metal wire, and at the same time drives the ball 58 to slide and move downward on the fixed rod 57. If the cutter 34 is not worn, the cutter 34 will quickly and directly cut the metal wire when it contacts it. If it is worn, the hydraulic rod 3 will still press the cutter 34 downward according to the original pressure. At this time, the cutter 34 When it contacts the metal wire, it will first pause and then press downward. At the same time, the ball 58 is in the slide groove 54, and the cutter 34 is in a paused state and cannot drive the ball 58 to continue moving. Since the ball 58 is partially embedded in the cutter 34, the ball 58 cannot fall downward on its own. However, since the slide groove 54 is in an inclined state and the fixing rod 57 is partially away from the bottom of the slide groove 54, the side of the ball 58 loses the restriction of the fixing rod 57, and the gravity of the ball 58 itself causes the ball 58 to roll downward along the slope of the slide groove 54, pushing the rotating rod 56 to rotate in the direction of the electric telescopic rod 41 during the rolling process. The other end of the rotating rod 56 pushes the upper end of the fixing rod 57, causing the fixing rod 57 to slide into the slide groove 54, thereby causing the fixing rod 57 and the rotating rod 56 to be both received in the slide groove 54. At the same time, the ball 58 rotates to the bottom of the slide groove 54 to push the switch of the controller 55, notifying the staff that the cutter 34 is worn, thereby reducing the work of the staff to check the wear degree of the cutter 34 every day.

[0040] Then, if Figure 2-6The ball 58 shown in the figure turns on the controller 55, so that the straightening roller 2 stops moving, and the electric telescopic rod 41 and the electromagnet 43 are started. At this time, since half of the cutter 34 in the inner tube of the electric telescopic rod 41 is located below the square opening and lower than the position of the second ratchet 421, when the electromagnet 43 is turned on, the cutter 34 will not be attracted by the electromagnet 43. The magnetic force emitted by the electromagnet 43 repels the magnetic force on the magnetic plate 343, thereby pushing the magnetic plate 343 to move away from the electromagnet 43, and at the same time stretching the spring 421. The electric telescopic rod 41 is retracted to the electromagnetic field, and the cylinder 342 is driven to move with it, so that the cylinder 342 is separated from the cutter 34 and loses the fixation of the cutter 34; at the same time, the electric telescopic rod 41 extends toward the cutter 34, and the cutter 34 is stuck in the inner tube of the electric telescopic rod 41, and the ratchet 2 421 is engaged with the ratchet 1 341. At the same time, the cutter 34 pushes the cutter 34 in the inner tube of the electric telescopic rod 41 to compress the spring. When the electric telescopic rod 41 is retracted, the cutter 34 is driven to move in the same direction. When the electric telescopic rod 41 is retracted to the electromagnetic field, the electric telescopic rod 41 is retracted to the electromagnetic field, and the cutter 34 is retracted to the electromagnetic field. When the cutter 34 is directly below the iron 43, the cutter 34 is attracted by the electromagnet 43 and connected to the electromagnet 43. At this time, the spring 2 ejects the cutter 34, and the electric telescopic rod 41 extends again, and the cutter 34 in the inner tube of the electric telescopic rod 41 is stuck on the inner tube of the hydraulic pipe. Since the position of the cutter 34 is lower than that of the original cutter 34 at this time, the cutter 34 will not be stuck by the ratchet 1 341. When the cutter 34 is stuck in the hydraulic rod 3, it is attracted by the magnetic block 311, so that the cutter 34 moves toward the magnetic block 311. , and the electromagnet 43 and the electric telescopic rod 41 are turned off at the same time. At this time, the magnetic plate 343 loses the repulsive magnetic force of the electromagnet 43, and the spring 1 332 moves the magnetic plate 343 toward the cutter 34, so that the cylinder 342 is stuck in the hydraulic rod 3, and then the cutter 34 is fixed. The device can automatically replace the cutter 34 after the wear of the cutter 34 is detected, which reduces the workload of the staff and also reduces the waste of wire caused by the wear of the cutter 34, which makes the metal wire cut in different sizes.
