By controlling the action of the electric telescopic rod 6 and the second motor 9, the position of the cutting assembly and the rotation speed of the cutting knife 8 can be conveniently adjusted, and the operation is simple and easy.

[0026] In a further preferred embodiment of the utility model, the support assembly includes two electric guide rails 10 installed on the top of the base 1; a support plate 11 fixed on the moving parts of the two electric guide rails 10; a placement plate 12 installed on the top of the support plate 11, and the placement plate 12 is provided with a plurality of slots for limiting the pins of the thermal resistor; two positioning assemblies arranged on the support plate 11 for positioning the pins of the thermal resistor.

The support plate 11 provides stable support for the placement plate 12. The card slot is used to limit the thermistor pins to prevent the pins from moving or shaking during the cutting process. The positioning assembly is used to accurately position the thermistor pins, which can ensure that the thermistor pins maintain a stable position during the cutting process, further improve the cutting accuracy, and the operation is simple and easy.

[0031] In this embodiment, the cylindrical shaft 18 provides a support and rotation basis for the conveyor belt 19. This design allows the conveyor belt 19 to circulate around the cylindrical shaft 18. When the reciprocating motor is working, its output shaft will drive the cylindrical shaft 18 fixed thereto to rotate, and then drive the conveyor belt 19 to circulate, thereby keeping the thermal resistor pins clamped and fixed.

The design of the adjustment block makes it easier to rotate the adjustment bolt 16.

[0038] To sum up, compared with the related art, the present device can cut the thermistor pins by setting a cutting component, and can clamp the thermistor pins to be cut by cooperating with the supporting component and the conveyor belt 19 to prevent the thermistor pins from being offset when being cut, thereby affecting the cutting accuracy.
