The present invention is not limited thereto and the improved structure of the present invention may be applied to other kinds of applicators as well and is within the scope of the present invention.

As shown in fig. 2-7, the magazine assembly of a hair clip applier includes a magazine for housing a plurality of ligation clips, and a pusher jaw 4 for pushing the ligation clips. The plurality of ligation clips comprise a ligation clip 13 to be inserted (a ligation clip to be inserted into a jaw) which is positioned at the most distal end of the clip bin and ligation clips which are stored in a row at the near side of the ligation clip 13 to be inserted; openings of the ligation clamps are horizontally placed on a bottom plate of the clamping bin in sequence towards a clamp feeding direction, a first clamping arm 11 of each ligation clamp is attached to the left side wall of the clamping bin 3, a second clamping arm 12 of each ligation clamp is attached to the right side wall of the clamping bin 3, and a plurality of first elastic clamping pieces 33 which are tilted upwards along the clamp feeding direction are arranged on the bottom plate of the clamping bin at equal intervals; push away the clamping piece 4 including what connect gradually push away the clamping piece body 41 with push away the clamping piece head, push away the clamping piece head and push away clamping piece body 41 and to a lateral buckling relatively, push away clamping piece body 41 and cover in the top of the ligature clamp except waiting to go into pincers ligature clamp 13, push away the clamping piece head and stretch into the clamp storehouse 3 inside and be close to waiting to go into pincers ligature clamp 13 setting, push away the equidistant third elasticity card 411 that is provided with a plurality of edges and send the clamp direction and perk downwards that is pushing away clamping piece body 41.
