As shown in fig. 1, 2 and 3, as a preferred embodiment of the present invention, the driving assembly 1 includes:
a main drive shaft 2 for connection with a power take-off unit;
a first transmission shaft 3, one end of which is coaxially and rotatably disposed with the plurality of planetary gears 9, and the other end of which is relatively fixedly disposed with the main driving shaft 2 through the second connecting pin 601, wherein the second connecting pin 601 is in sliding fit with the first transmission shaft 3 along the axial direction, and when the second connecting pin 601 is far away from the main driving shaft 2, the first transmission shaft 3 is in sliding fit with the main driving shaft 2;
Further, as a preferred embodiment of the present invention, the first transmission shaft 3 is provided with an annular receiving groove 301 and a limiting groove 302 at the side wall position;

In an embodiment of the present invention, the structure of the driving assembly 1, the mutual matching between the structures, and the implementation of the switching tool are explained in detail, and in particular, in use, when the rock formation strength is too high to exceed the bearable range of the traveling bit 13, the pressure limiting member 5 is contracted (the pressure limiting member 5 and the switching control member 6 are in sliding fit and are not directly connected), and then the traveling bit 13 is driven by the switching control member 6 and the outer transmission gear 11 to slide (the three are fixedly connected as shown in fig. 1 and 2), and during the sliding process, the second connecting pin 601 up to the end (corresponding to the right end in the figure) of the switching control member enters the main driving shaft 2, (corresponding to fig. 3 below) will lock the freedom of relative rotation between the first driving shaft 3 and the main driving shaft 2 (because the limiting holes on the main driving shaft are spaced, and the second connecting pin 601 is of a discontinuous annular groove type, and when the second connecting pin 601 enters, the pin connection effect can be achieved), the second connecting pin 601 entering the main driving shaft 2 can push the first connecting pin 201 to slide, at this time, the first connecting pin 201 slides out from the tail end of the second transmission shaft 4, the main driving shaft 2 does not drive the second transmission shaft 4 to rotate through the first connecting pin 201, but drives the first transmission shaft 3 to rotate through the second connecting pin 601, at this time, in the planetary gear mechanism, the planetary gear 9 becomes a power gear, the breaking bit 14 is driven to stably rotate around the axis of the main driving shaft 2, so as to form a stable circular advancing area, and rock strata with higher strength are processed through the breaking bit 14 (it is necessary to supplement that the first connecting pin 201 is of a non-annular structure and cannot rotate around the axis of the main driving shaft 2, it may have any non-circular or circular configuration such as a cross shape, and the space of the main drive shaft 2 for receiving the first connecting pin 201 is a profile thereof) (in this case, if the power output is still performed by the second transmission shaft 4, the gear ring 10 cannot be stably fixed, and the guarantee that the revolution around the main drive shaft 2 cannot be stably maintained during the travel of the drill 14 is broken).
As shown in fig. 2, 3 and 5, as a preferred embodiment of the present invention, a first auxiliary drill 15 and a second auxiliary drill 16 are further included;
the first auxiliary drill bit 15 is coaxially and fixedly connected with the sun gear 8;
