Abstract:
Secateurs, comprising:a first and a second secateur limb in a pivotal relationship with each other for cooperative operation; a bearing screw coupled to the secateur limbs to provide the pivotal relationship; a cutting blade fixedly connected to the first secateur limb and coupled to the bearing screw to provide a pivotal motion for the cutting blade in relation to the second secateur limb; an anvil adjustably connected to the second secateur limb and positioned to adjust in relation to the cutting blade when the secateur limbs are pivoted; a bearing coupled to the anvil and the second secateur limb to provide a pivot axis for the anvil in relation to the second secateur limb; a first screw that extends through the anvil and the bearing and connects to the second secateur limb for maintaining a relationship between the anvil, the bearing, and the second secateur limb; an arcuate slot in the anvil arranged concentric with the pivot axis provided by the bearing; a second screw that extends through the arcuate slot for adjusting the anvil; a nut that extends through the second secateur limb and cooperates with the second screw to clamp the anvil to the second secateur limb; at least one of a head portion of the second screw and an end surface of the nut having an annular surface directed toward the anvil to provide an annular cutting edge, such that the annular cutting edge protrudes into a lateral surface of the anvil when the second screw and the nut are tightened, thereby preventing slippage in an adjustment of an alignment between the cutting blade and the anvil to provide a light-gap-free relationship.
