[0033] The staff controls the pen-type electric push rod 501 to push the fan-shaped plate 503, and the fan-shaped plate 503 pushes the thermistor to slide along the placement groove 1 6, so that the distance between it and the blade 14 can be automatically adjusted, and the shaping and cutting length of the pin can be quickly adjusted. Then, the cylinder 10 drives the pressing plate 11 to descend, and the pressing plate 11 drives the pressure component 12 and the blade 14 to descend at the same time. Since the height of the pressing block 1201 of the pressure component 12 is lower than the height of the blade 14, it can reach the base 2 before the blade 14. The pressing block 1201 limits the top of the thermistor through the placement groove 2 1205 and the pin groove 2 1206;

[0034] During this process, the spring 1204 is compressed and can transfer the pressure of the cylinder 10 to the pressure block 1201, and reduce the impact force between the pressure block 1201 and the base 2, so that the pressure block 1201 can fit tightly with the base 2 and will not hinder the continued descent of the blade 14.
