The value of the attention is due to the number of teeth of the planetary teeth 3〇3a and the second external gear 3G3b (7) "An external gear external gear 303a and the second outer same are the same or different, if the first same speed, in other words: , =^ The difference in the number of 'and thus obtain a variety of different designs' can be borrowed. In addition, due to the difference device 3 (); 2: the planetary gears 303, the first, the palpitations, which are differently caught, the area of the sun gear 304, the mutual. S-coupling, so it can effectively reduce the difference between the main body 302 and the differential device 30 that can be carried out by the larger device: the stress that must be withstood, so the horsepower is lost, and the high-definition horsepower loses 9/18. It is not easy to be friends, it has the advantages of compact structure and good stability. - Ligang, 'Fig. 3' Fig. 3 is a top-section profile of the precision quantitative peristaltic pump. 9mt) The speed device 30 rotates, so that the rollers are cocked and the two J 敕 tube 4G 'and then the hose 4G — The end of the fluid is subjected to the hose 4〇=::: Na, and the hose 4 is taken between the rollers 3〇lb. - ———————————————————————————————————————————————————————————————————————————————————————————— The smoothness on the rim and the fluid outflow dose and FIG. 5 'Fig. 4 is the creation of the precision quantitative nucleus device: Yi Er Benz = coffee pumping device 2, the above-mentioned fine: fixed = provided - species Precision 蹲, 精 — θ, 疋 蠕 蠕 蠕 蠕 蠕 不同 不同 蠕 〇 〇 〇 〇 〇 〇 〇 〇 〇 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦 浦Moreover, the structural features of 4〇 have been revealed in the above, and soft officials.

The above-mentioned missing member can be changed by changing the structure of the elastic fixing member 60. In the present embodiment, as shown in FIG. 4, the end of the missing member 7 can be formed. The two oppositely disposed sweet-skinned structures 70 and the other end of the clamping member 70 form a u-shaped inflammatory body', and the two ends of the squeezing body 7〇2 are respectively connected with two curved pliers structures 7〇ι, which are shaped like Lost structure; then the butterfly member 60 can be a collar (10). The actual assembly method of the above-mentioned projectiles, such as 6 〇, 好 4 〇, and 7 夹持 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ A schematic plan view of the top view; a plurality of hose limit ports / can be formed between the flat body structure 20 and the second body 3〇2 of the precision quantitative screwing fruiting device 2, and the housing structure shown in FIG. 20 and the second body meet to form two hoses ^ position S ' so that the human water end of the hose 40 4Q] one of the technical basins of the second tube limit π S ' then the hose 4 〇 Wei, the roller fiber, so that the water outlet end 402 of the hose protrudes from the other hose limit port s. At this time, the jacket 60丨 is sleeved on the soft water end of the soft f (10) and the water outlet end. Department, finally = U-shaped inflammatory body 7〇2 with clamping member 7〇 from the housing structure 2〇 toward the mountain = 6Q direction to clamp the collar 6G1 at the water inlet end 4〇] The part between the good and the ^° 〇2 is such that the collar 601 is subjected to the shuttle press of the sweetener 7〇2 and is owed to the official 〇2, so when the rollers are pressed and the hose is released, The water inlet end and the water outlet end of the hose 4Q 4 The influence of = on the flow and direction of the fluid in the hose 40 increases the accuracy. Since the position of the hose is more limited between the hose limit ° S, the bottom edge 703 of the U-shaped a 2 of the clamping member 7 will be abutted. In the limiting portion R, it is more effective to prevent relative movement of the 11/18 70 relative to the rollers 3〇113. In addition, since one end of the clamping member forms two oppositely disposed sweet-scented structures 701, and the other six-clamped clamping body 7〇2 of the holding member 7〇, when the clamping member 70 is to be clamped The collar structure 7〇1 needs to be simply applied to the sides of the U-shaped clamp body 702, and the two curved clamps #€ 702 are relatively slid. When the water inlet end 401 and the water outlet end 402 are not covered by the hose cover 1 and the hose 40 is applied to the hose 40, the contact area between the collar 601 and the hose 40 is large, and the e 40 tube 40 is connected to each other. Hand h knife 旯", add 裱 601 and soft, which will affect the amount of fluid in the hose 4G; This creation of the heart & ^ 1 material f can be Na. In summary, the clamping member 7〇 and the elastic solid in the 60 il r Lipu device 2 are simple to manufacture, easy to assemble, not easy to malfunction, and the kiss is simple and convenient.
