[0012] 1. In the utility model, by setting a clamping device, when it is necessary to cut the brass rod, first place the brass rod on two brackets, and then rotate the rotating wheel. The rotation of the rotating wheel drives the threaded rod to rotate. Since the threads on the surface of the threaded rod are mutually reverse threads with the rotating wheel as the center, when the rotating wheel drives the threaded rod to rotate, the two movable plates connected by the threads on its surface will move toward each other on the surface of the vertical rod. The two movable plates move toward each other on the surface of the vertical rod, driving the two outer clamping rings to move toward each other. The two outer clamping rings move toward each other, driving the two inner clamping rings to move toward each other. The two inner clamping rings move toward each other to clamp and fix the brass rod. When the inner clamping ring contacts and clamps the brass rod, the inner clamping ring will be The clamping ring is subjected to force to drive the hinged plate to move, and the movement of the hinged plate pushes the two movable plates to move away from each other on the surface of the U-shaped rod. The movement of the two movable plates on the surface of the U-shaped rod away from each other will drive the spring to stretch, so as to utilize the resilience of the spring to avoid rigid contact between the inner clamping ring and the brass rod. At the same time, when the brass rod is clamped and fixed, the cylinder and the motor are started, and the cylinder starts to drive the support frame to move downward, and the support frame moves downward to drive the motor and the cutting knife to move downward. At the same time, the motor starts to drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the cutting knife to rotate. The cutting knife rotates to complete the cutting operation of the brass rod. Through the cooperation of the above-mentioned structure, the device can provide a buffer space when cutting the brass rod to avoid deformation of the brass rod during the cutting process, thereby ensuring the cutting effect.

[0013] 2. In the utility model, by setting a limit device, when it is necessary to adjust the distance between the two clamping devices, first loosen the bolt and screw it out from the inside of the threaded hole. The bolt and the threaded hole are separated, so that the sliding plate loses the limit in the inside of the sliding groove. At this time, the sliding plate can be moved. The movement of the sliding plate in the sliding groove drives the sliding plate to move in the long groove. The movement of the sliding plate in the long groove drives the U-shaped plate to move. When the U-shaped plate moves to a suitable position, the bolt is screwed into the corresponding threaded hole again to fix the position of the sliding plate in the sliding groove at this time. Through the cooperation of the above structure, the distance between the two clamping devices can be adjusted, thereby meeting the purpose of clamping and fixing brass rods of different lengths.

The setting of the spring 211 has the effect of limiting the position of the moving plate 210 on the surface of the U-shaped rod 209.

[0029] In this embodiment: an adjusting device 3 is provided on the side of two movable plates 207 , and the adjusting device 3 includes an L-shaped rod 31 , which is fixedly installed on the side of two movable plates 207 , and a bracket 32 ​​is fixedly installed on one end of the L-shaped rod 31 away from the movable plate 207 . When it is necessary to adjust the distance between the two clamping devices 2, first loosen the bolt 35 and screw the bolt 35 out from the inside of the threaded hole 36. The bolt 35 and the threaded hole 36 are separated, so that the sliding plate 34 loses its limit in the inside of the sliding groove 33. At this time, the sliding plate 34 can be moved. The movement of the sliding plate 34 in the sliding groove 33 drives the slide plate 202 to move in the long groove 201.

[0034] Working principle: By setting the clamping device 2, when the brass rod needs to be cut, first place the brass rod on the two brackets 32, and then rotate the rotating wheel 205. The rotation of the rotating wheel 205 drives the threaded rod 204 to rotate. Since the threads on the surface of the threaded rod 204 are reverse threads with the rotating wheel 205 as the center, when the rotating wheel 205 drives the threaded rod 204 to rotate, the two movable plates 207 connected by threads on its surface will move toward each other on the surface of the vertical rod 206. The two movable plates 207 move toward each other on the surface of the vertical rod 206, driving the two outer clamping rings 208 to move toward each other. The two outer clamping rings 208 move toward each other, driving the two inner clamping rings 214 to move toward each other. The two inner clamping rings 214 move toward each other to clamp and fix the brass rod. When the inner clamping rings 214 contact and clamp the brass rod, The inner clamping ring 214 is subjected to force to drive the hinged plate 213 to move, and the movement of the hinged plate 213 pushes the two movable plates 210 to move away from each other on the surface of the U-shaped rod 209. The movement of the two movable plates 210 on the surface of the U-shaped rod 209 in the direction away from each other will drive the spring 211 to stretch, so as to utilize the resilience of the spring 211 to avoid the rigid contact between the inner clamping ring 214 and the brass rod. At the same time, when the brass rod is clamped and fixed, the cylinder 5 and the motor 9 are started. The cylinder 5 is started to drive the support frame 6 to move downward. The support frame 6 moves downward to drive the motor 9 and the cutting knife 8 to move downward. At the same time, the motor 9 is started to drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the cutting knife 8 to rotate. The cutting knife 8 rotates to complete the cutting operation of the brass rod. Through the cooperation of the above-mentioned structure, the device can provide a buffer space when cutting the brass rod to avoid deformation of the brass rod during the cutting process, thereby ensuring the cutting effect. When it is necessary to adjust the distance between the two clamping devices 2, first loosen the bolt 35 and screw the bolt 35 out from the inside of the threaded hole 36. The bolt 35 and the threaded hole 36 are separated, so that the sliding plate 34 loses its limit in the inside of the sliding groove 33. At this time, the sliding plate 34 can be moved. The movement of the sliding plate 34 in the sliding groove 33 drives the slide plate 202 to move in the long groove 201. The movement of the slide plate 202 in the long groove 201 drives the U-shaped plate 203 to move. When the U-shaped plate 203 moves to a suitable position, the bolt 35 is screwed into the corresponding threaded hole 36 again to fix the position of the sliding plate 34 in the sliding groove 33 at this time. Through the cooperation of the above structure, the distance between the two clamping devices 2 can be adjusted, thereby meeting the purpose of clamping and fixing brass rods of different lengths.
