Claim:
A grip device for moving a front floor of a vehicle, comprising; a grip frame comprising a front frame and a rear frame integrally mounted at a rear end of the front frame and extending downwardly; a front clamping member mounted at each of both ends of the front frame through a front transverse moving member so as to hold a flange portion around a suspension mounting hole of the front floor; a rear clamping member mounted at each of both ends of the rear frame through a rear transverse moving member and an upper or lower fixing member so as to clamp a member flange portion of the front floor; a front guide rail mounted at each of both sides of the lower surface of the front frame along a length direction thereof; a front slider slidably movable along the front guide rail so as to slide the front clamping member; a front linear actuator mounted at each of both sides of the front surface of the front frame and provided with an operating rod connected to one side of a connecting bracket of the front clamping member; a cylinder housing connected to the front transverse moving member through the connecting bracket and provided with a piston integrally disposed to the piston rod therein; a link housing mounted at a lower portion of the cylinder housing, provided with a fixing pin therein and having an open bottom; a clamp arm disposed in the link housing, an upper end of which is hinged to a lower end of the piston rod and one side portion of which is provided with a bent slot to be engaged with the fixing pin; an upper self-aligning pad unit disposed to a lower end of the link housing, supported by resilient force of a spring, being able to move according to an angle of the flange portion around the suspension mounting hole of the front floor so as to clamp an upper surface thereof; and a lower self-aligning pad unit disposed to a lower end of the clamp arm so as to face the upper self-aligning pad unit, supported by resilient force of a spring, and being able to move corresponding to the angle of the flange portion around the suspension mounting hole so as to clamp a lower surface thereof.
