Preferably, the vibration conducting piece 3 is arranged perpendicular to the tool head holder 2.
Preferably, the vibration conducting plate 3 is connected to the upper end surface of the extruder 1.
Preferably, the tool head fixing seat 2 is provided with a connecting seat 5 in a protruding manner, and the vibration conducting piece 3 is connected with the bottom surface of the connecting seat 5.
Preferably, a signal acquisition and amplification circuit 6 is arranged on the tool head fixing seat 2, and the vibration sensor 4 is connected with the signal acquisition and amplification circuit 6.
Preferably, the vibration conducting plate 3 adopts a hollowed-out flat plate-shaped structure so as to better conduct vibration.
In the technical scheme, the extruder 1 and one end of the vibration conducting piece 3 are fixed together through the screws, the other end of the vibration conducting piece 3 is connected with the tool head fixing seat 2, and the vibration sensor 4 is adhered to the vibration conducting piece 3 through glue.
When an external force touches the extruder 1 from any direction, vibration is generated, and the vibration conducting sheet 3 is fixedly connected with the extruder 1, so that the vibration on the extruder 1 is also conducted to the vibration conducting sheet 3. When the hot bed 7 is in contact with the extruder 1, vibrations are generated, which are transmitted from the extruder 1 to the vibration-conducting sheet 3, and which cause a slightly recoverable elastic deformation of the vibration-conducting sheet 3. At this time, the vibration sensor 4 is triggered and generates an electrical signal, and the signal acquisition and amplification circuit 6 acquires and amplifies the electrical signal generated by the vibration sensor 4 and transmits the electrical signal to the external main control board, so that the main control board adopts a leveling manner known in the prior art to perform leveling, which is not described herein.
