Gearbox structure with vice box

The invention provides a gearbox structure with a vice box. Two power sources and a gearbox are connected conveniently and reliably, power output cannot be interrupted, the number of output power gears is increased, and the vehicle demand is met. The gearbox structure with the vice box comprises double input shafts and a power output shaft arranged coaxially, wherein the double input shafts comprise a second hollow input shaft and a first input shaft; the first input shaft penetrates through a hollow inner cavity of the second hollow input shaft and is coaxial to the second hollow input shaft;the input end of the second hollow input shaft is connected with an external second power source; the input end of the first input shaft is connected with an external first power source; a second transmission gear is fixed to the output end of the second hollow input shaft in a sleeving way; the output end of the first input shaft is post-positioned relative to a second transmission gear and is sleeved with a coupling sy
