[0023] The temperature sensor 13, vibration sensor 14, sound sensor 15 and torque sensor 16 are installed inside the cylinder 1. When in use, the elastic movable sleeve 3 can be extended and retracted by pushing the pullable movable rod 4; when the multi-parameter sensor device is connected to the motor shaft using the threaded coupling 18, the movable limit rod 5 knob can fix the elastic movable sleeve 3; when disassembly is required, the threaded coupling 18 in the cylinder is rotated in the opposite direction to separate the multi-parameter sensor device and the motor shaft.

[0026] The temperature sensor 13, the vibration sensor 14 and the sound sensor 15 are connected to the torque sensor via a fixed shaft 17, and the fixed shaft is connected to the motor shaft via a threaded coupling 18, so that the torque sensor 16 is driven to rotate through the rotation of the motor to transmit relevant parameters.
