Abstract:
1. A loading mechanism, comprising: a fastening board defining a pivot hole at the center portion of the fastening board and a sliding guide adjacent to the pivot hole; a cam comprising a first surface and a second surface opposite to the first surface, the first surface defining a locating hole at the center portion thereof, and the second surface defining an annular guide, wherein the annular guide comprises a first annular sliding groove, a second annular sliding groove, a third annular sliding groove, and a fourth annular sliding groove communicating with each other in series to form a closed annular groove, the centers of the first and third annular sliding grooves coincide with the center of the locating hole; a rotary pivot; and a load module comprising two guiding poles, a follower fastened to one end of the two guiding poles, a clamping member fastened to the other end of the two guiding poles, wherein one end of the rotary pivot is rotatably fastened in the pivot hole of the fastening board, and the other end of the rotary pivot is fastened in the locating hole of the cam, the cam is capable of driven to rotate, and the cam drives the follower to slide along the first, second, third, and fourth annular sliding grooves in order to drive the load module to slide along the sliding guide; wherein a distance between the intersection of the first annular sliding groove and the sliding guide, and the locating hole is greater than the distance between the intersection of the third annular sliding groove and the sliding guide, and the locating hole, and the distance between the intersection of one of the second annular sliding groove and the fourth annular sliding groove and the sliding guide, and the locating hole is gradually decreased from the first annular sliding groove to the third annular sliding groove.
