Claim:
A multi-spindle gearbox system, comprising: a gearbox comprising: a base comprising a first sidewall and a second sidewall substantially perpendicular to the first sidewall, the first side wall defining an assembly hole therethrough, the assembly hole being a stepped hole with an aperture decreasing inwardly from an outer surface of the first sidewall toward an inner surface of the first sidewall, thereby forming a stepped inner wall; and a sealing cover detachably covering the base and forming a hollow box space together with the base, the sealing cover comprising an end wall positioned opposite to the first sidewall of the base, the end wall defining a guiding hole therethrough coaxially with the assembly hole of the base, a hollow output sleeve spindle comprising a spindle body and a connecting shaft formed at one distal end of the spindle body, the connecting shaft being rotatably assembled to the assembly hole of the base, wherein the connecting shaft is a stepped hollow shaft with a diameter thereof decreasing away from the spindle body corresponding to an inner diameter of the assembly hole of the base, the spindle body comprises a hollow first output shaft, a hollow second output shaft and a hollow third output shaft; the first output shaft, the second output shaft, and the third output shaft are sleeved on together, the second output shaft is sandwiched between the first output shaft and the third output shaft; a gear assembly received within the assembly hole of the base to rotatably assemble the output sleeve spindle to the base of the gearbox, wherein the gear assembly comprises a first gear, a second gear, and a third gear respectively rotatably assembled to the corresponding first output shaft, the second output shaft, and the third output shaft; and a cable-receiving barrel assembled within the gearbox with a first end fixed to the assembly hole and an opposite second end exposed to the outer side of the gearbox by passing through the guiding hole of the sealing cover.
