ABSTRACT:
A guiding device includes a connecting member, a first clamping arm, and a second clamping arm. The first clamping arm defines a first restricting groove and a first receiving groove in an end, and the first restricting groove communicates with the first receiving groove. The second clamping arm defining a second restricting groove and a second receiving groove in an end, and the second restricting groove communicates with the second receiving groove. The first clamping arm and the second clamping arm are rotatably connected to the connecting member. When the first clamping arm resists the second clamping arm, the first restricting groove and the second restricting groove cooperatively form a guiding portion. The first receiving groove and the second receiving groove cooperatively form a receiving portion. The receiving portion is substantially perpendicularly to the guiding portion to form a T-shaped groove.
