18V Auto- quick chuck drill(ST-MCD001)

The present invention relates generally to tools and more particularly to a
powered drill for drilling holes using drill bits and/or power bits having
a hex shaped shank. Changing drill bits in a drill is a slow, time consuming procedure that essentially requires three hands. One hand is used to activate the tool's release mechanism (typically requiring a movement that requires the use of at least two fingers or a thumb and a finger), one hand is used to remove and insert a drill bit, and a third hand is required to hold and stabilize
the drill during the removal/insertion procedure. Because humans only have
two hands, the third hand is usually replaced by holding the drill in between the user's knees or between the user's arm and chest. Therefore, this procedure is very time consuming, awkward, and sometimes results in dropping the drill.

Accordingly, the present invention provides for a quick-release chuck
assembly that requires only two hands for the removal/insertion of a drill
bit where the release trigger is within finger's reach of the drill handle
and the release trigger can be activated with a single finger movement.
The present invention also provides for a powered drill that incorporates
the aforementioned quick-release chuck assembly.

 regarding the new product compare with  the old quick chuck drill  below:

a sleeve disposed about said spindle and spring biased in a locked position of said sleeve, said sleeve capable of being moved axially to an unlocked position to permit insertion and removal of such bit in said spindle, said sleeve being capable of returning to the locked position of said sleeve,and a trigger having a finger receiving portion and an actuator portion, said finger receiving portion extends from said housing in a position enabling the user to actuate said finger receiving portion of said trigger with a finger of the hand holding said handle portion of said housing, said actuator portion of said trigger being in physical communication with an engagement portion of said sleeve wherein the activation of said finger receiving portion of said trigger causes said sleeve to move axially to the unlocked position of said sleeve, said engagement portion of said sleeve comprises at least one ear that extends from an outer surface of said sleeve.
