Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the power output device includes a bracket 1, a motor 2 is mounted on the bracket 1, and the motor 2 is a servo motor.

The bracket 1 is also provided with a power shaft 3. Two mounting plates 11 are mounted on the support 1, two supporting bearings 4 are mounted on each mounting plate 11, and the power shaft 3 is sleeved in the supporting bearings 4.

The power shaft 3 has three parts: segment i 31, segment ii 32, and segment iii 33. The section II 32 and the section III 33 are respectively connected to two ends of the section I31, the section II 32 and the section I31 are connected through a universal shaft I34, and the section III 33 and the section I31 are connected through a universal shaft II 35.

Referring to fig. 3, fig. 3 is an enlarged view of a portion a of fig. 2, and a universal shaft i 34 shown in fig. 3 is connected between a segment i 31 and a segment ii 32. The two ends of the universal shaft I34 are provided with insertion holes 39, and the segment I31 or the segment II 32 is inserted into the insertion holes 39. The insertion hole 39 is further provided with a key groove (not shown), and the portions of the segments i 31 and ii 32 inserted into the insertion hole 39 are further provided with keys inserted into the key grooves, so that relative rotation between the segment i 31 or ii 32 and the universal shaft i 34 is restricted.

The periphery of the end part of the universal shaft I34 is also provided with a pin hole 36, an internal thread is arranged in the pin hole 36, the pin hole 36 extends into a plug hole 39, and a jackscrew 37 is screwed in the pin hole 36, so that the section I31 or the section II 32 is limited to be pulled out of the plug hole 39.

When it is necessary to separate the section II 32 or the section III 33 from the section I31, the section II 32, the section III 33 or the section I31 is extracted by screwing out the jackscrew 37.

The section II 32 and the section III 33 are respectively sleeved in the two support bearings 4, and a certain distance is reserved between the two support bearings 4 to improve the guiding effect.

As shown in fig. 2, the power output apparatus of this example further includes a synchronizing mechanism 5, and the synchronizing mechanism 5 includes a timing belt 51, a pulley i 52, and a pulley ii 53. Wherein, runner I52 sets up the output at motor 2, and II 53 settings of runner are on power shaft 3, specifically set up on II 32 of festival section, and hold-in range 51 cover is established in I52 and II 53 holistic periphery that constitute of runner to when I52 is rotatory in the drive runner of motor 2, it is rotatory to drive II 53 of runner through hold-in range 51, thereby it is rotatory to drive power shaft 3, reaches power take off's purpose.
