[0073] A stabilizing component is arranged at the top and bottom of the assembly frame 27 and one side of the transmission plate 26, and is used to limit the rotation of the transmission shaft A28 or the transmission shaft B30;

[0074] In this embodiment, the stability maintenance component includes:

[0075] Two stabilizing rods 37, the two stabilizing rods 37 are respectively connected to the top and bottom of one end of the stabilizing rod 37 in a transverse sliding manner, a pushing frame 38 is fixedly connected to the middle of the stabilizing rod 37, and a linkage column 39 is fixedly connected to one end of the pushing frame 38;

[0076] An extension frame A40, the extension frame A40 is fixedly connected to one side of the transmission plate 26, one end of the extension frame A40 is fixedly connected to a positioning shaft rod 41, one end of the positioning shaft rod 41 is fixedly connected to an adjustment plate 42, the top and bottom ends of the adjustment plate 42 are both provided with linkage grooves 43, and two linkage columns 39 are movably connected to the inside of the two linkage grooves 43;

[0077] A positioning ear 44 is fixedly connected to one side of the bottom end of the adjustment plate 42, and a conductive plate 45 is rotatably connected to one side of the adjustment plate 42. A linear guide rod 46 is vertically fixedly connected to the bottom end of the inner side of the assembly frame 27, and a support plate 47 is slidably connected to the outer side of the linear guide rod 46, and the linkage shaft 33 is also rotatably connected to one end of the support plate 47;

Since the limiting strip is also slidably connected to the inside of the limiting groove, when the driving shaft 32 rotates, the linkage shaft 33 will follow the rotation of the driving shaft 32, and when the linkage shaft 33 moves into the transmission shaft A28 or the transmission shaft B30, the transmission shaft A28 or the transmission shaft B30 will follow the rotation;

[0081] In this embodiment, one side of the positioning ear 44 and one end of the extension frame B48 are fixedly connected with a pin, and the conductive plate 45 is rotatably connected between the two pins. The setting of the pin can stably assemble the conductive plate 45 and improve the smoothness of the linkage of the conductive plate 45.

[0082] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0083] Working principle: See Figure 8 and Fig. 9First, insert the assembly shaft 19 into the assembly cylinder 3 until the transmission spur gear 29 is meshed with the guide toothed disc 4, then pull up the limit plate 16 to move the positioning card rod 15 out of the matching lock hole 18, thereby unlocking one of the stabilizing frames 6, and then push one of the stabilizing frames 6 to drive the stabilizing plate 7 close to the assembly shaft 19. Since the linkage pin 11 is also movably connected to the inside of the push slot 13, when one of the stabilizing frames 6 is displaced, the linkage pin 11 can be used to move in the push slot 13 to push the linkage plate 7. The moving ring 9 rotates and pulls the other stabilizing frame 6 through another linkage pin 11, so that the two stabilizing plates 7 are close to each other until they fit the surface of the assembly shaft 19, and the assembly shaft 19 is positioned. Then, the force on the limiting plate 16 is released, and the coil spring 17 is deformed when the limiting plate 16 is pulled. Then, when the limiting plate 16 is released, the positioning card rod 15 can be pulled downward with the help of the coil spring 17, so that the positioning card rod 15 is connected with the corresponding matching lock hole 18, so as to lock the position of the stabilizing frame 6;

[0084] The PMN-PT crystal is bonded to the bonding seat 24, and then the electric push rod 49 is started to push the support plate 47 to move downward under the limit of the linear guide rod 46. Under the connection between the support plate 47 and the linkage shaft 33, the linkage shaft 33 can follow the displacement of the support plate 47, and cooperate with the connection between the support plate 47 and the extension frame B48. When the extension frame B48 follows the displacement of the support plate 47, the positioning ear 44 can be pushed by the conductive plate 45, so that the adjustment plate 42 is rotated under the support of the positioning shaft 41. Since the two linkage columns 39 are movably connected in the two linkage slots 43 respectively, when the conductive plate 45 pushes the adjustment plate 42, the linkage slot 43 under the adjustment plate 42 can be used to push the linkage column 39 under the assembly frame 27, so that the stabilization rod 37 below is away from the transmission shaft A28, thereby releasing the restriction on the transmission shaft A28.

[0085] At the same time, the linkage column 39 above the adjustment plate 42 will follow the rotation of the adjustment plate 42, driving the upper stabilizing rod 37 to move toward the transmission shaft B30 until the stabilizing rod 37 is in close contact with the transmission shaft B30, increasing the friction force of the transmission shaft B30 to form a rotation lock of the transmission shaft B30, and then starting the drive motor 34 to drive the driving spur gear 35 to rotate, prompting the driving spur gear 35 to shift the reduction spur gear 36, thereby driving the driving shaft 32 to rotate, and under the connection between the driving shaft 32 and the linkage shaft 33, the linkage shaft 33 can transmit the power of the driving shaft 32 to the transmission shaft A28, prompting the transmission shaft A28 to drive the transmission spur gear 29 to rotate, and under the connection between the transmission spur gear 29 and the guide toothed disk 4, the transmission spur gear 29 moves along the guide toothed disk 4, thereby adjusting the contact position between the PMN-PT crystal and the cutter of the cutting device body 1;

[0086] When it is necessary to adjust the cutting angle of the PMN-PT crystal, first start the electric push rod 49 to pull the linkage shaft 33 upward until the linkage shaft 33 moves into the transmission shaft B30. At the same time, under the linkage of the conduction plate 45, the stabilizing rod 37 above the assembly frame 27 is moved away from the transmission shaft B30, and the stabilizing rod 37 below the assembly frame 27 is tightly fitted with the transmission shaft A28. Then start the drive motor 34 to cause the drive shaft 32 to rotate, so that the power of the drive shaft 32 is transmitted to the transmission shaft B30 with the help of the linkage shaft 33, so that the transmission bevel gear 31 moves the drive shaft 32, and then the guide seat 23 is driven to rotate with the help of the adjustment shaft 21. Under the connection between the guide seat 23 and the bonding seat 24, the bonding seat 24 can be adjusted to the corresponding angle, so as to adjust the cutting angle of the PMN-PT crystal. After the PMN-PT crystal is adjusted, it can be cut by the cutting device body 1.
