Description
Technical field
The utility model relates to a kind of assistive device of musical instrument, relates in particular to a kind of violoncello eyelid retractor.
Background technology
Contrabass, as violoncello, bass bass, be mainly to rely on qin foundation by qin body bearing diagonal on the ground, and the bottom of violoncello qin foundation and the surface of contact on ground is very little when playing, substantially be a contact, tend to skid on the ground, be difficult to support qin body, affect playing effect.
Summary of the invention
The utility model provides a kind of violoncello eyelid retractor, described a kind of violoncello eyelid retractor can play the supporting role to violoncello, increased the contact area on qin foundation and ground, strengthened the friction force on qin body and ground, can prevent that violoncello from skidding with ground when playing, assurance playing effect.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of violoncello eyelid retractor, comprise perpendicular support, triangular groove, projection, axle ball, bolt, base, bearing diagonal, slipmat, described violoncello eyelid retractor, base is connected and fixed by bolt with perpendicular support, at the center of two supporting surface intersections, there is a ball recess, groove the inside is embedded with an axle ball that diameter is identical with groove, it between axle ball and groove, is clearance fit, groove inside surface is relative smooth with axle outer surface of ball, axle ball can rotate freely in groove, on axle ball, there is a columniform projection, the upper bottom surface of projection has a triangular groove, triangular groove is the cone groove with cylindrical protrusions coaxial cable, at the perpendicular support back side, it is bearing diagonal, perpendicular support with bearing diagonal is integrated, at base and bearing diagonal bottom surface, be fixed with scum rubber slipmat.
Compared with prior art, the beneficial effects of the utility model are:
A violoncello eyelid retractor, simple in structure, with low cost, increased the contact area on qin foundation and ground, strengthened the friction force on qin body and ground, can prevent that violoncello from skidding with ground when playing, assurance playing effect.
