[0024] Further, the directional locking mechanism includes a locking screw 201 rotatably connected to the outside of the housing 3, two locking disks 205 fixed at both ends of the rotating shaft 4, and two fixing blocks 203 fixed at both ends of the outside of the housing 3.

The outside of the locking screw 201 is rotatably connected to a moving plate 202 through a thread, and both ends of the moving plate 202 are fixed with latches 204 respectively adapted to the inner sides of the two guide holes 207. The rotating shaft 4 is locked through the directional locking mechanism, so that the rotating shaft 4 and the multiple rotating disks 101 outside it cannot rotate, so that the top rod 108 and the arc-shaped long groove 111 can be stably fitted to prevent the two from separating, thereby ensuring that the distance between the pressure plate 1 51, the pressure plate 2 52, the pressure plate 3 53 and the shell 3 does not change, so that the distance between the pressure plate 1 51, the pressure plate 2 52, the pressure plate 3 53 on both sides does not change, so that a stable clamping force can be applied to the sections of different diameters of the variable-diameter copper tube.

[0025] Furthermore, the three locking holes 206 are arranged in a circle, and the three locking holes 206 are arranged alternately with the three adjusting top blocks 103 located inside the same rotating disk 101; When the latch 204 is inserted into any one of the locking holes 206 on the locking plate 205 , the top of one of the adjusting top blocks 103 can be brought into contact with the top rod 108 , thereby improving the accuracy of the spacing adjustment.

[0026] Furthermore, each of the pressing plates 1 51, 2 52, and 3 53 is provided with a centering positioning mechanism of the same structure, such as the centering positioning mechanism provided on the pressing plate 1 51, which includes two hinge shafts 301 rotatably connected to the upper and lower sides of the pressing plate 1 51, a through slot 303 provided at the middle section of the pressing plate 1 51, and a trigger switch 312 installed on one side of the pressing plate 1 51, a clamping plate 302 is fixed on one side of the two hinge shafts 301, and a lever 307 is fixed at the middle section of the two hinge shafts 301, one end of the two levers 307 is provided with a sliding pin slot 308, and a fixed screw is fixed on the inner end of the through slot 303.

Two sliding pins 306 respectively matched with the inner sides of the two sliding pin grooves 308 are fixed on the upper and lower sides of the slider 305, and two armatures 309 aligned with the two electromagnets 310 are fixed on one side of the slider 305. One side of the slider 305 is elastically connected to the other end of the through slot 303 through a second spring 311. The trigger switch 312 is electrically connected to the two electromagnets 310 through a control circuit. A rubber pad 110 is provided on one side of each pressing plate 1 51, pressing plate 2 52, and pressing plate 3 53. When one side of the pressing plate 1 51, the pressing plate 2 52, and the pressing plate 3 53 is completely in contact with the outer side of the reduced diameter copper tube, the two clamping plates 302 respectively located on the upper and lower sides of the reduced diameter copper tube can be synchronously merged, and thrust can be synchronously applied from the upper and lower sides of the reduced diameter copper tube to center the reduced diameter copper tube in the middle position of one side of the pressing plate 1 51, the pressing plate 2 52, and the pressing plate 3 53, thereby improving the accuracy of the positioning of the reduced diameter copper tube and preventing the reduced diameter copper tube from shifting up and down during cutting, and further increasing the contact area between the pressing plate 1 51, the pressing plate 2 52, the pressing plate 3 53 and the reduced diameter copper tube, thereby better preventing the reduced diameter copper tube from deforming.

[0027] Furthermore, the clamping mechanism includes a motor 8 installed on one side of the base plate 1 and a threaded shaft 7 rotatably connected to the inner side of the base plate 1 at the middle position, the driving end of the motor 8 is fixedly connected to one end of the threaded shaft 7, two outer ends of the threaded shaft 7 are provided with two external threads in opposite directions, and the threaded shaft 7 is threadedly connected to the two slides 2 through the external threads at both ends, and two guide rods 6 are fixed at the inner side of the base plate 1 at the two ends, and the two guide rods 6 are both penetrated and slidably connected to the inside of the two slides 2; Through the clamping mechanism, the two slides 2 are driven to move in opposite directions so that the two slides 2 are merged with each other, and the two slides 2 respectively drive the two shells 3 to merge with each other, and the two shells 3 respectively drive the pressure plate 1 51, the pressure plate 2 52, and the pressure plate 3 53 on one side to merge, so that the two pressure plates 1 51, the two pressure plates 2 52, and the two pressure plates 3 53 on both sides can clamp and position the reduced diameter copper tube from both sides.

[0028] Working principle: When positioning a plurality of sections of a reducer copper tube with different diameters, the sections with different diameters of the reducer copper tube are aligned with two pressing plates 1 51, two pressing plates 2 52, and two pressing plates 3 53, respectively. Figure 2 As shown), according to the diameter of the different sections of the variable diameter copper tube, the spacing between the pressure plate 1 51, the pressure plate 2 52, and the pressure plate 3 53 on both sides is adjusted, and the cover plate 11 on the upper side of the housing 3 is opened. The debugging personnel rotate the adjusting screw 104 of the spacing adjustment mechanism (combined with the hexagonal wrench) Fig. 9 and Fig.10 ), the adjusting screw 104 rotates and drives the adjusting top block 103 to move inside the slide groove 102 through the thread. Since one side of the pressure plate 1 51, the pressure plate 2 52, and the pressure plate 3 53 are slidably connected to the shell 3 through two guide rods 106, and under the elastic force of the first spring 109, the baffle 107, the guide rod 106 and the top rod 108 can apply a thrust to the inside of the shell 3, so that the top rod 108 can be closely attached to the outside of the rotating disk 101, and the two sides of the directional locking mechanism are rotated. The locking plate 205 can drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the multiple rotating plates 101 on the outside thereof to rotate, and each rotating plate 101 drives the multiple adjusting top blocks 103 on the outside to rotate. When the push rod 108 slides from the outside of the rotating plate 101 to the upper side of an inclined surface 105 on one side of the adjusting top block 103, under the guidance of the inclined surface 105, the push rod 108 slides to the inner side of the arc-shaped long groove 111 located at the top of the adjusting top block 103. When the adjusting top block 103 moves toward the rotating plate 101, the push rod 108 is rotated. When adjusting the outside, the pressing plate 1 51, the pressing plate 2 52, and the pressing plate 3 53 can be moved away from the shell 3. When the adjusting top block 103 is adjusted toward the inside of the rotating disk 101, the pressing plate 1 51, the pressing plate 2 52, and the pressing plate 3 53 can be moved close to the shell 3. Thus, the distance between the pressing plate 1 51, the pressing plate 2 52, and the pressing plate 3 53 and the shell 3 can be adjusted by adjusting the position of the adjusting top block 103. Thus, the distance between the two pressing plates 1 51, the two pressing plates 2 52, and the two pressing plates 3 53 on both sides can be adjusted, so that the difference in the spacing between the two pressing plates 1 51, the two pressing plates 2 52, and the two pressing plates 3 53 on both sides is equal to the difference in the diameters of the different sections of the variable diameter copper tube. Thus, the clamping force can be applied to multiple positions of different diameters on the outside of the variable diameter copper tube at the same time through the two pressing plates 1 51, the two pressing plates 2 52, and the two pressing plates 3 53 with unequal spacings. While ensuring the positioning stability, the deformation of the variable diameter copper tube caused by the concentrated clamping force can be avoided, thereby facilitating the cutting of the variable diameter copper tube. Three adjusting top blocks 103 are arranged on the outside of each rotating disk 101, and each adjusting top block 103 can be adjusted to different positions, so that different distances can be maintained between the pressure plate 1 51, the pressure plate 2 52, the pressure plate 3 53 and the shell 3, so that the distances between the pressure plates 1 51, the pressure plates 2 52, and the pressure plates 3 53 on both sides can be adjusted. According to the reducer copper tubes of different sizes, the positions of the three adjusting top blocks 103 outside each rotating disk 101 are adjusted first. The three adjusting top blocks 103 can keep different distances between the pressure plates at the corresponding positions and the shell 3. When it is necessary to adjust the reducer copper tubes of different sizes, the pressure plates 101 at the corresponding positions can be adjusted. When clamping the copper tube, it is only necessary to rotate the rotating shaft 4 by 120°, and the rotating shaft 4 drives the multiple rotating disks 101 on the outside thereof to rotate by 120°, thereby driving the multiple adjusting top blocks 103 to rotate by 120°, and the adjusting top blocks 103 at different positions are brought into contact with the top rod 108, so that the distance between the pressing plates 1 51, 2 52, and 3 53 on both sides can be quickly adjusted, so that the variable diameter copper tubes of different sizes and specifications can be clamped and fixed, which greatly increases the use flexibility of the device, so that when positioning the variable diameter copper tubes of various sizes and specifications, the clamping efficiency of the variable diameter copper tubes can be greatly improved; After adjusting the angle of the rotating disk 101 each time, the locking screw 201 of the directional locking mechanism is rotated, and the locking screw 201 drives the movable plate 202 to move through the thread, and the movable plate 202 drives the two latches 204 to move, so that the two latches 204 move on the inner sides of the two guide holes 207 respectively. When the ends of the two latches 204 are respectively inserted into the inner sides of the locking holes 206 located on one side of the two locking disks 205, the two locking disks 205 can be locked, and the two locking disks 205 cannot rotate, so that the rotating shaft 4 and the multiple rotating disks 101 outside it cannot rotate, so that the push rod 108 and the guide rod 106 can be stably fitted to prevent the two from separating, thereby ensuring that the distance between the pressing plate 1 51, the pressing plate 2 52, the pressing plate 3 53 and the housing 3 does not change, so that the distance between the pressing plates 1 51, the pressing plates 2 52, and the pressing plates 3 53 on both sides does not change, so that a stable clamping force can be applied to sections of different diameters of the variable diameter copper tube, ensuring the reliability of the device when it is repeatedly used; When clamping the variable diameter copper tube, the motor 8 controlling the clamping mechanism drives the threaded shaft 7 to rotate. Since the outer side of the threaded shaft 7 is respectively penetrated and rotatably connected to the inside of the two slides 2 through two external threads in opposite directions at both ends, when the threaded shaft 7 rotates, the two slides 2 can be driven to move in opposite directions through the external threads, so that the two slides 2 are merged with each other, and the two slides 2 respectively drive the two shells 3 to merge with each other, and the two shells 3 respectively drive the pressure plate 1 51, the pressure plate 2 52, and the pressure plate 3 53 on one side to merge, so that the two pressure plates 1 51, the two pressure plates 2 52, and the two pressure plates 3 53 on both sides can clamp and position the variable diameter copper tube from both sides; When one side of each pressing plate 1 51, pressing plate 2 52, and pressing plate 3 53 contacts the outer side of the variable diameter copper tube, the rubber pad 110 can provide protection for the surface of the variable diameter copper tube to prevent indentations on the surface of the variable diameter copper tube. When one side of the pressing plate 1 51, pressing plate 2 52, and pressing plate 3 53 is completely in contact with the outer side of the variable diameter copper tube, the trigger switch 312 of the centering positioning mechanism can be triggered. The trigger switch 312 controls the two electromagnets 310 to be energized through the control circuit to generate electromagnetic attraction to the two armatures 309, so that the slider 305 can be attracted to the end where the electromagnet 310 is located, so that the slider 305 slides on the outer side of the fixed rod 304. Through the sliding cooperation between the two sliding pins 306 and the two sliding pin grooves 308, when the slider 305 drives the two sliding pins 306 to move, the two sliding pins 306 can be used to give the two dials The rod 307 applies thrust, and the two levers 307 respectively drive the two hinge shafts 301 to rotate in opposite directions at an equal speed. The two hinge shafts 301 respectively drive the clamping plates 302 on one side to rotate in opposite directions, so that the two clamping plates 302 are synchronously merged. The two clamping plates 302 are respectively located above and below the reduced diameter copper tube. When the two clamping plates 302 are synchronously merged, thrust can be applied synchronously from the upper and lower sides of the reduced diameter copper tube, so that the reduced diameter copper tube is centered in the middle position on one side of the pressure plate 1 51, the pressure plate 2 52, and the pressure plate 3 53, so that the reduced diameter copper tube contacts the rubber pad 110, thereby improving the positioning accuracy of the reduced diameter copper tube, preventing the reduced diameter copper tube from shifting up and down during cutting, and further increasing the contact area between the pressure plate 1 51, the pressure plate 2 52, the pressure plate 3 53 and the reduced diameter copper tube, so as to better prevent the reduced diameter copper tube from deforming.
