Automatic clip driver

An automatic clip driver comprising:

• an upper case having a downwardly-opened rectangular box shape, the upper case including a cover coupling section formed with a longitudinally-extending spring receiving slot and a clip insertion hole arranged at the rear of the spring receiving slot, and a knob mounting section arranged at the front of the cover coupling section while being integral with the cover coupling section, the knob mounting section having a knob slide slot for receiving a pushing knob while allowing the pushing knob to be longitudinally slidable, and a pair of guide rails respectively arranged at opposite side surfaces of the knob mounting section and adapted to guide the sliding movement of the pushing knob;
• a lower case coupled to the upper case while being mated with the upper case, the lower case being mounted with a pair of V-shaped plate springs at a front end thereof;
• an opening/closing cover hingably coupled to a rear end of the upper case to selectively open the cover coupling section of the upper case;
• the pushing knob received in the knob slide slot of the knob mounting section to be slidable along the knob slide slot;
• a clip pushing member interposed between the upper and lower cases, the clip pushing member being in contact with the guide rails of the upper case to be longitudinally slidable along the guide rails and serving to forwardly urge clips received in a clip receiving space defined between the upper and lower cases;
• a first elastic member connected between the opening/closing cover and the clip pushing member and adapted to forwardly or rearwardly urge the clip pushing member in accordance with an opening or closing movement of the opening/closing cover;
• and
• a second elastic member connected between the pushing knob and the upper case and adapted to urge the pushing knob to be always positioned at a rear end of the knob slide slot.
