The working principle is as follows: one end of a mechanical shaft is fixedly inserted into the clamping joint 202, the mechanical device shaft drives the rotating shaft 201 to rotate for a certain angle through the clamping joint 202, so that the rotating shaft 201 drives the adapter rod 203 to rotate to the other end in the middle of the movable opening 100, the external rod drives the sliding column 313 at the bottom of the external rod to slide in the annular groove 110, the bottom of the sliding column 313 slides on the tops of a plurality of movable balls 112 in the installation cavity 111, at the moment, the sliding column 313 drives the lantern ring 312 to rotate, the lantern ring 312 elongates the extension spring 311 until one side of the adapter rod 203 abuts against the buffer block 101 on one side of the inner wall of the movable opening 100, meanwhile, the adapter rod 203 drives the upright column 320 at one end of the bottom of the adapter rod to rotate in the annular cavity 12, the upright column 320 drives the sliding rod 321 to rotate along the external connection hole 120, so that the sliding rod 321 drives the movable column 332 and the sliding block 331 to slide on the two sliding rails 3210 of the sliding column 332, until the sliding block 331 moves to one end of the carrying seat 330 and abuts against the two limiting columns 334, therefore, the assembly state is achieved, when the mechanical device shaft is separated from the clamping head 202, the extension spring 311 contracts to pull the adapter rod 203 to reset, the moving block and the sliding block 331 move to the other end of the carrying seat 330 in the same way, the cushion 3310 on one side of the sliding block 331 props against the two touch switches 341, the received electric signals are transmitted from the two information transmission ports through the information module 340, and therefore the mechanical signals are converted into the electric signals.
