The drive assembly 100 is also coupled to the first carriage 300 for driving the first carriage 300 in a first direction.

As shown in fig. 1 and 2, the guide frame 400 is movably provided on the first carriage 300 in the first direction, and the drill box 500 is connected to the guide frame 400. Specifically, the drill box 500 and the guide frame 400 are detachably connected.

As shown in fig. 1 and 2, the direction changing assembly 600 includes a gear 610 and a rack 620. The gear 610 has an outer circumferential portion, the rack 620 has a side portion, and the outer circumferential portion of the gear 610 is engageable with the side portion of the rack 620. The rotator 700 includes a first body and a rotating portion rotatably provided on the first body with respect to the first body. The first body is provided on one of the guide frame 400 and the first carriage 300, and the rotation part is connected to the gear 610 so that the gear 610 is driven to rotate around the axis. A rack 620 is provided on the other of the guide frame 400 and the first carriage 300 to drive the guide frame 400 and the drill box 500 to move in a first direction with respect to the first carriage 300. The axis extends in a direction parallel to a second direction (e.g., a front-to-rear direction in fig. 1) perpendicular to the first direction.

That is, if the first body is mounted on the guide frame 400, the rack 620 is mounted on the first carriage 300. While the rotary part and the gear 610 rotate around the axis, the first body, the guide frame 400, and the drill box 500 move in a first direction with respect to the rack 620 and the first carriage 300.

If the first body is mounted on the first carriage 300, the rack 620 is mounted on the guide frame 400.
