Its further technical scheme is: described input shaft gear comprises upper strata input shaft gear and lower floor's input shaft gear, the upper strata input shaft gear is connected by meshing transmission with the direct output shaft gear of wherein one group of relative arrangement, and lower floor's input shaft gear and another are organized direct output shaft gear and be connected by meshing transmission.

Its further technical scheme be: described power shaft is connected with casing with taper roll bearing by radial ball bearing, and radial ball bearing is positioned at box top, and taper roll bearing is positioned at Box Cover.

Described output shaft is connected radial ball bearing and is connected with casing with transition axis.

Described output shaft stretches out on the termination below the Box Cover and has for the bayonet socket that drill bit is installed.

Owing to take above technical scheme, a kind of six hole drill tools of the utility model have following beneficial effect:

1. use a kind of six hole drill tools of the utility model to cooperate with drilling machine, once can finish the processing of position, six holes, compare with traditional radial drilling machine, working (machining) efficiency has very big raising.

2. owing to a kind of six hole drill tools of the utility model, the mutual alignment between its six output shafts is all by the hole bit position set of the required processing of workpiece, and once finish in six holes, thereby can eliminate the one by one error brought of machining of every hole, both made easy for installationly, and can improve installation effectiveness again, reduced cost.

3. a kind of six hole drill tools of the utility model are reasonable in design, simple and compact for structure, economical and practical.

Be further described below in conjunction with the technical characterictic of drawings and Examples to a kind of six hole drill tools of the utility model.
