The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As shown in Figure 1 and Figure 2, structural representation for the utility model embodiment one, the biasing assembly that this fast clamp mechanism mainly comprises the clamp assemblies of clamping nail and clamp assemblies can be moved between open position and closing position, wherein, clamp assemblies is made up of B jaw 4, A jaw 5, torsion spring 6 and pivotal axis 7, and A,

B jaw

5,4 are articulated on the pivotal axis 7, torsion spring 6 is enclosed within on the pivotal axis 7, one end inserts B jaw 4, and the other end inserts A jaw 5, can realize closed reduction to jaw; Biasing assembly comprises lining 8, slip cap 10, spring 11 and casing 12, slip cap 10 is packed into behind the casing 12, can in casing 12, endwisely slip, reset by spring 11, lining 8 is that mold insert is connected with slip cap 10, pivotal axis 7 is interference fit with slip cap 10, can not relatively rotate, A, B jaw left side are provided with

jump ring

3,3 pairs of jaws of jump ring carry out axial location, jump ring 3 is stuck on the pivotal axis 7, and A, B jaw right side and lining 8 butts, nail 2 are clamped between A, the B jaw and under impulse pin 9 effects and are driven into workpiece 1.

Middle part, composition surface when A of the present utility model,

B jaw

5,4 closures has the V-shaped groove 14 that is used to clamp nail, and each jaw faying face top is provided with inclined-plane 13, described inclined-plane 13 forms V-notch in the jaw engage top, be convenient to packing into of nail, the jaw right-hand member is provided with and the adaptive conical pilot hole of nail head, the Circularhole diameter that conical pilot hole forms in the jaw right side is a bit larger tham the diameter of impulse pin 9, is convenient to impulse pin 9 and backs down A,
