Limiting and combining with the outer casing 5 1; then inserting the front end of the output shaft 53 from the rear end of the inner toothed seat 52, so that the output shaft 5 3 is passed through the bearing 5 2 2 which is sleeved on the front end of the inner toothed seat 52, and then Extending from the front end of the outer casing 5 1 , and engaging a C-shaped buckle 5 3 3 on the annular groove 5 3 1 of the output shaft 5 3 , the output shaft 5 3 and the inner adapter 5 201229405 ' 2 and the outer casing 5 1 The inner peripheral edge of the gear set 5 3 2 disposed at the rear end of the output shaft 5 3 is engaged with the internal teeth provided on the inner perforation 5 2 1 of the inner adapter 52; the planetary gear set 5 is further engaged. The 4 series is inserted into the rear end of the inner toothed seat 52 and installed at the rear of the output shaft 5 3 , and a gear 5 4 1 ' is disposed in the axial direction of the front end of the planetary gear set 5 4 to make the gear 5 4 1 set in the output. Gear set 5 3 2 with shaft 5 3 rear end As a salivation drive, the outer circumference of the entire planetary gear set 53 is engaged with the internal teeth provided on the inner perforation 5 2 1 of the inner adapter 52 (as shown in FIG. 9); then the spacer 5 5 In the rear of the star gear group 5 4, the gear box interface panel 5 6 is placed in the outer casing by the guide groove 5 2 4 provided at the periphery of the bottom end of the casing 5 1 by the front end of the casing. 5 1 rear end 'several fixing holes 5 6 3 of the gear box interface panel 5 6 can be aligned with the inner buckle 5 2 6 central perforation 5 2 7 The component 5 1 4 locks and bonds the outer casing 5 1 , the inner adapter 5 2 and the gear box interface panel 5 6; finally, the pressing piece 5 15 provided on the periphery of the bottom end of the outer casing 5 1 is disposed on the gear box interface panel 5 . The fitting groove 5 6 4 at the end of the 6 6 4 is press-embedded, so that the outer casing 5 1 can be further embedded and combined with the gear box interface panel 56 and constitute a micro reduction gear box 5. With the above-mentioned structural composition, the micro-shaped gearbox 5 can be integrally formed of plastic in the inner toothed seat 52 and directly aligns with the front end flange 5 2 2 of the outer casing 5 1 with the front end flange 5 2 2 . Limiting, and the inner toothed seat 5 2 is used to make a buckle 5 2 6 and the insert hole 5 1 3 provided in the rear part of the outer casing 5 1 is combined with the card to press the front end and the rear end of the inner toothed seat 5 2 The housing is integrated with the housing 1 5 1 ', and the outer casing can be assembled by the inner tooth holder 52. 201229405 5 1 is made of a metal material to increase the structural strength of the inner tooth holder 52, so that the inner tooth holder 5 m to the material thickness B can be greatly reduced 'relatively reduce the material cost of the inner tooth holder 52; then the fixing hole 563 at the periphery of the gear box interface panel 56 and the positioning buckle 526 of the inner tooth holder 52 are centrally perforated 5 2 7 pairs of down' can lock the outer casing 5 1 , the inner adapter 5 2 and the gear box interface panel 56 into a micro reduction gear box 3 ' with the locking element 5 1 4 and at the same time by the inner sill 5 2 The outer peripheral edge is sleeved in the metal outer casing 5 1 and the metal is preferably made of steel. When the outer end of the outer casing 5 1 has a plurality of screw holes 512 and the other is intended to be used together with the micro shape When the 5-speed gearbox means concludes mouth 'of the housing 5 so that the particular station can be in - a given structural strength to make the practical effect of binding specifically to the locking device. Moreover, the micro reduction gear box 5 composed of the above-mentioned members, as shown in the twelfth to fourteenth drawings, is provided when the self-gear box interface panel 6 is passed through the periphery of the lock member 6 through the periphery thereof. The hole 5 6 2 is combined with a small motor 7 at the rear, so that the transmission gear 7 2 of the front end of the rotating mandrel 7 i of the small motor 7 is inserted into the planet from the center of the gear box interface plate 65. After the center of the rear stage of the gear set 514 is engaged (as shown in Fig. 14), and the small motor 7 is further operated by the power supply connection, the rotating spindle 7 1 of the small motor 7 at a higher rotational speed is provided. The transmission gear 7 2 fixed to the front end of the rotating spindle 7 1 is further coupled with the planetary gear set 54 and the gear set 5 3 2 at the rear end of the output shaft 53 and the internal perforation 5 2 1 of the internal adapter 5 2 The inner tooth of the ring is used as a ringing transmission, and a speed reduction mechanism can be formed as in the conventional method to provide the output shaft 53 of the micro reduction gear box 3 as a rotary power output with low rotation speed and high torque. 10 201229405 The invention described above can solve the shortcomings of the similar products in use, and its efficacy and advantages are remarkable, and it has never been disclosed in the market publications. [Simple description of the diagram] The first figure is a three-dimensional exploded schematic diagram of the structure of the conventional micro-reduction gearbox.
