When the motor 100 is replaced by the replacement device provided by the embodiment of the present invention, when the motor 100 needs to be installed, since the guide groove 33 includes the tapered opening 331 and the strip-shaped slide groove 332, it is only necessary to align the two guide pins 24 substantially with the large end of the tapered opening 331. Under the action of gravity, the top of the sliding sleeve 11 abuts against the flange of the motor 100 to be replaced to support the motor 100 to be replaced, and then the mounting assembly 1 and the first docking assembly 2 are lowered so that the guide pin 24 gradually slides into the bar-shaped sliding groove 332 from the tapered opening 331 until the guide pin 24 moves to the bottom of the bar-shaped sliding groove 332, at which time each positioning ball 23 is aligned with the annular groove 32. Then, the installation component 1 is lowered continuously, so that the sliding sleeve 11 is displaced axially relative to the first positioning cylinder 21, and the positioning balls 23 are gradually pushed to move towards the annular groove 32 until the sliding sleeve 11 abuts against the first limiting flange 22, at this time, the output shaft of the motor 100 to be replaced is meshed with the input shaft of the power output device 200, and each positioning ball 23 is already located in the annular groove 32 and abuts against the inner peripheral wall of the sliding sleeve 11, thereby achieving the effect of locking the positioning ball 23 in the annular groove 32 (see fig. 3).
