Detailed description of the invention
The manual hold down gag of a kind of inclined-plane self-locking double as depicted in figs. 1 and 2, comprise the mount pad 1 play fixed supporting role, also comprise for workpiece pressing 1 and upside be provided with groove one 2-1 wedge pressure head 1, for workpiece pressing 27 and upside be provided with groove two 8-1 wedge pressure head 28 and for driving the slide-bar 5 of described wedge pressure head 1 and described wedge pressure head 28, described mount pad 1 is provided with vertical installing hole 1-1, horizontal installing hole one 1-2 and horizontal installing hole two 1-3, slide in described vertical installing hole 1-1 and be provided with described slide-bar 5, described slide-bar 5 sidewall symmetry is provided with cammed surface one 5-1 and cammed surface two 5-2, sliding in described horizontal installing hole one 1-2, being provided with matches with described cammed surface one 5-1 forms the described wedge pressure head 1 of self-locking inclined-plane pair, sliding in described horizontal installing hole two 1-3, being provided with matches with described cammed surface two 5-2 forms the described wedge pressure head 28 of self-locking inclined-plane pair, side, described mount pad 1 upper end is installed with the flexible member 1 resetted for ordering about described wedge pressure head 1 to the right, described mount pad 1 upper end opposite side is installed with the flexible member 26 resetted for ordering about described wedge pressure head 28 left, described mount pad 1 lower end sidewall is rotatablely equipped with the crowbar 9 for upwards prizing described slide-bar 5.
In the present embodiment, described flexible member 1 and described flexible member 26 are reseting plate spring, and flat spring is compared with traditional cylindroid helical-coil compression spring, and structure is simple, takes up room less.
In the present embodiment, described flexible member 1 upper end is welded on described mount pad 1 upper end, and described flexible member 1 lower end is arranged in groove one 2-1 on the upside of described wedge pressure head 1.
