Force adjustable spring-clamp capo

Abstract

The present utility model discloses a force adjustable spring-clamp capo, comprises a string-engaging arm and a damping arm, the string-engaging arm and the clamping arm are hinged together by a composite pressing rivet, wherein a pressure adjustment mechanism is further arranged in a middle of the clamping arm, including: a pressure spring, a regulation screw and a regulation nut, by the pressure adjustment mechanism, a collapsing length of the pressure spring is adjusted, making the force of the spring change (Hooke's law), which makes the clamping force of the capo adjustable, it can also be operated by a single hand of a player as the spring-damp capo, thus owns a simple and easy operation, making a player be able to adjust to a best clamping force according to a requirement of the instrument thereof, to achieve a role of a tune transfer assistance perfectly. By a planar thrust bearing embedded in the regulation nut, the present utility model further reduces the resistance generated by the friction between the regulation nut and the clamping arm greatly, thus simplifies the operation of a force adjustment, and achieves the purpose of effort saving.
