[0023] In this example, the fixing mechanism also includes a baffle 15, and the baffle 15 is sleeved on the outside of the pull rod 14, and a sliding rod 16 is symmetrically provided on the outside of the baffle 15, and a sliding block 17 is sleeved on the corresponding position of the outside of the sliding rod 16, and one end of the sliding block 17 is movably connected to the pull rod 14 through a connecting rod 18, and connecting blocks 13 are symmetrically provided on the relative outsides of the two sliding blocks 17 in the chamber 12, and the relative inner walls of the connecting blocks 13 are symmetrically provided with card grooves adapted to the sliding blocks 17, and the lower ends of the two connecting blocks 13 pass through the bottom of the knife seat 7 and are fixedly connected to the cutter 9, one end of the pull rod 14 is connected to a fixing plate 19, and the other end of the pull rod 14 is connected to a pull handle outside the knife seat 7, and a spring 20 is sleeved on the outer wall of the pull rod 14 between the baffle 15 and the fixing plate 19. Through the fixing mechanism, the cutter 9 can be easily and quickly disassembled and installed, so that when the cutter 9 is worn or damaged or needs to be disassembled for maintenance and repair, it is convenient to disassemble, maintain, overhaul or replace it, which is convenient to use and more practical. In this example, the tensioning and positioning assembly includes a flexible rubber block 10, and the flexible rubber block 10 is symmetrically arranged on both sides of the cutting knife 9 at the bottom of the knife seat 7, and a support plate 21 is symmetrically arranged on the top of the base 1. Two guide wheels 22 are distributed up and down on one side of the support plate 21, and the upper guide wheel 22 is rotatably connected to the support plate 21 through a connecting shaft. A slide groove 2 is opened at a symmetrical position on one side of the two support plates 21, and a slide rod 23 is arranged in the slide groove 2. A slider 24 and a spring 25 are sleeved on the outer side of the slider 23, and the spring 25 is located above the slider 24. The guide wheel 22 located below is rotatably connected to the slider 24 through a connecting shaft. Then, in this example, when the enameled wire passes between the two guide wheels 22, the enameled wire is pulled during transportation, which causes it to transmit part of its force to the guide wheel 22 located below, so that it drives the connected slider 24 to slide and squeeze the spring 25, so that the two guide wheels 22 pull the enameled wire passing through up and down, thereby making the enameled wire tight for subsequent cutting processing. Through the tensioning positioning component, the enameled wire can be kept in a tight and straightened state while being transported, and the flexible rubber block 10 is used to realize the positioning and fixing of the enameled wire during cutting, thereby avoiding displacement during cutting and affecting the cutting effect. In this example, the pull rod 14 is movably connected to the knife seat 7, the baffle 15 is annular, and the baffle 15 is slidably connected to the pull rod 14, the two ends of the connecting rod 18 are respectively hinged to the slider 17 and the side wall of the pull rod 14, and the two ends of the spring 1 20 are respectively fixedly connected to the baffle 15 and the fixed plate 19, so as to transmit power, and the baffle 15 cooperates with the elastic force generated by the spring 1 20 to act on the fixed plate 19 to drive the pull rod 14 to reset. In this example, the guide wheel 22 is I-shaped, and the outer side of the guide wheel 22 is wrapped with a rubber layer. The two ends of the spring 25 are respectively fixedly connected to the slider 24 and the inner wall of the slide groove 2 to guide and limit the enameled wire. In this example, the transmission rod 5 is inclined, and the two ball heads 6 are distributed on the left and right to drive the knife seat 7 to move up and down to achieve the cutting operation.

[0024] The working principle of the utility model is as follows: when in use, the enameled wire is passed from the top of the guide wheel 22 on one side, then passed under the guide wheel 22 located below, and then passed through the guide wheel 22 on the other side, and then turned to the top of the guide wheel 22 on the other side. The guide wheels 22 distributed up and down are used to keep the enameled wire taut for cutting operation. When cutting, the motor 3 can be started to drive the turntable 4 to rotate, and the turntable 4 cooperates with the ball head 6 and the transmission rod 5 to drive the knife seat 7, so that the knife seat 7 moves up and down, so that the knife seat 7 drives the cutter 9 to move down and cooperate with the cutting seat 11 to cut the enameled wire. At the same time, the flexible rubber block 10 will press the enameled wire below to achieve its positioning and fixation, so as to avoid displacement during cutting and affect the cutting effect. After long-term use, if the cutter 9 is worn or the knife becomes stiff, the pull handle can be pulled to drive the pull rod 14 to move, so that the pull rod 14 will drive the fixing plate 19 to move synchronously. The pull rod 14 is released to move the fixing plate 19 to cooperate with the baffle plate 15 to squeeze the spring 20, and at the same time, the pull rod 14 drives the connecting rod 18 to pull the connected sliding block 17 to slide relatively inwardly along the sliding rod 16, so that the sliding block 17 moves out of the slot, and then the cutter 9 is pulled to drive the connecting block 13 to move downward and separate from the knife seat 7 to complete the disassembly of the cutter 9, thereby facilitating the maintenance or replacement of the cutter 9. When installing the cutter 9, the above steps can be repeated to move the sliding block 17 between the notches of the installation connecting block 13, and then the connecting block 13 is inserted into the corresponding notch, and the pulling force applied to the pull handle is released, so that the fixing plate 19 drives the pulling rod 14 to reset under the elastic force of the spring 20, thereby driving the connecting rod 18 to push the connected fixing plate 19 to slide along the sliding rod 16, so that the sliding block 17 is stuck in the slot, realizing the restriction and fixation of the connecting block 13, thereby completing the installation of the cutter 9, which is convenient to use and practical.
