Claim:
A hand held quick-clamping device, comprising an adjusting rod 1 , a retaining handle 2 , a driving handle 3 , a first clamping block 4 , and a second clamping block 5 ; the adjusting rod 1 penetrating through the retaining handle 2 , and a set of adjusting sheets 6 , wherein the adjusting rod is a long rod for locking the first clamping block at one end thereof; the retaining handle has a holding portion at a lower end thereof and an upper end of the retaining handle is formed by a front receiving chamber and a rear receiving chamber which are spaced by an isolating rib section; an upper side of the retaining handle is installed with the second clamping block; a through hole communicated to the rear receiving chamber is formed in the hold portion and is pivoted with a release buckle; the rib section, the front receiving chamber and the rear receiving chamber are formed with respective holes for the movement of the adjusting rod and for receiving a set of adjusting sheets and a set of stop sheets; the retaining handle is installed with one end of a movable top shaft; and another end of the top sheet is installed with an axial shaft which ejects to the adjusting sheets; a top end of the driving handle is installed with a pivoted shaft so that the driving handle is pivoted to the retaining handle; and a top portion of a body of the driving handle resists against a top of the retaining handle; the second clamping block is engaged to and locked to any predetermined end of the adjusting rod; the second clamping block is firmly secured to be in front of the retaining handle and is positioned corresponding to the first clamping block; each sheet in the set of the adjusting sheets and the set of stop sheets has a respective slot for receiving the retaining handle to be placed in the front receiving chamber and the rear receiving chamber; each sheet of the adjusting sheets and stop sheets has a respective spring; wherein by above mentioned elements, when the driving handle is pressed and thus is actuated, the top portion of the driving handle will push the top shaft and the axial shaft of the driving handle will press the adjusting sheets at a front end thereof; thus by displacement of the adjusting sheets, the adjusting rod will be driven to move in one direction; thus the first and second clamping block will have the function of clamping and extending; further, by the releasing buckle to buckle the stop sheets, the angle of the sheets are calibrated so as to release the buckling action between the adjusting rod and the adjusting sheets; thereby, respective positions between the adjusting rod and the retaining handle is adjustable.
