[0005] Preferably, the handle is further provided with a guiding inclined surface, and the guiding inclined surfaces are symmetrically arranged on both sides of the positioning groove.

[0006] Preferably, the handle is also provided with a plurality of connection holes.

[0007] Preferably, the end of the positioning shaft is provided with an introduction cone surface.

[0013] The utility model is now further described with reference to the accompanying drawings.

[0014] like Figure 1 and Figure 2 As shown, a pinion assembly device for a planetary gear comprises a handle 5 and an upper magnet 6. The handle 5 is provided with a positioning shaft 52, a positioning groove 53, a positioning hole 51 and a guide slope 54. The positioning shaft 52 is arranged at the end of the handle 5, and is used to be inserted into the center hole 91 of the rotating disk 9, and matches the center hole 91. There is a clearance fit between the positioning shaft 52 and the center hole 91. The end of the positioning shaft 52 is provided with an introduction cone 521, and the introduction cone 521 is convenient for inserting into the center hole 91. The positioning groove 53 is located on one side of the positioning shaft 52, and the positioning groove 53 is used to be inserted into the connecting plate 95 of the rotating disk 9. The width of the positioning groove 53 matches the thickness of the connecting plate 95 to form a clearance fit. The top of the positioning groove 53 is symmetrically provided with two guide slopes 54, and the guide slopes 54 facilitate the positioning groove 53 to be inserted into the connecting plate 95. The positioning hole 51 is located on one side of the positioning groove 53, and the positioning hole 51 is used to be inserted into the rotating shaft 81 of the pinion 8 to realize the positioning of the pinion 8. The upper magnet 6 is installed in the magnetic hole 58 on the handle 5, and the magnetic hole 58 is located on one side of the positioning hole 51. The upper magnet 6 is installed in the magnetic hole 58, and the upper magnet 6 is arranged opposite to the functional magnet 7 on the pinion 8, and is used to attract the functional magnet 7 on the pinion 8 by magnetism. The functional magnet 7 is used to cooperate with the Hall sensor to detect the number of rotations of the pinion 8. The pinion 8 is arranged opposite to the sun shaft 92 on the turntable 9.

[0015] In order to facilitate connection with other devices, the handle 5 is further provided with a plurality of connection holes 56 .

[0016] When assembling the pinion 8, insert the rotating shaft 81 of the pinion 8 into the positioning hole 51, then rotate the pinion 8 so that the functional magnet 7 is adsorbed onto the upper magnet 6, and the pinion 8 is adsorbed onto the end of the handle 5 and will not fall off. Then align the positioning shaft 52 of the handle 5 with the center hole 91 of the turntable 9 and insert it into the center hole 91, and at the same time, make the positioning groove 53 and the connecting plate 95 arranged oppositely, and the positioning groove 53 is inserted into the connecting plate 95 under the action of the guide slope 54, and the positioning groove 53 and the center hole 91 make the pinion 8 and the sun shaft 92 on the turntable 9 in a coaxial state, and then insert the rotating groove at the bottom of the pinion 8 into the sun shaft 92 of the turntable 9, and since the position of the pinion 8 is fixed, the teeth of the pinion 8 can be accurately inserted into the tooth groove of the gear ring 93, and then the pinion 8 can be pressed with a tool, and the handle 5 can be pulled up to separate the functional magnet 7 of the pinion 8 from the upper magnet 6, and the installation of the pinion 8 is completed.

[0017] The small gear 8 is installed at an accurate position, has a high overall installation efficiency, saves effort, and does not hurt fingers.

[0018] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
