The utility model relates to the technical field of medical orthopedics appliances, specifically relates to a
microvessel generation stimulator, include: the
fixed frame is installed with the stud and at least two support screws on it, the lifting frame is installed with at least one move screw on it, the lifting frame is equipped with the guide groove that support screw passes through, still include knob, the knob rotatablely installed on the lifting frame, the knob is equipped with knob inner thread through -hole, and the knob is connected with the stud through the knob inner thread through -hole, the knob includes operating part, and the operating part is located between the
fixed frame and the lifting frame, taking the plane perpendicular to operating part rotation axis, the projection of operating part on the plane is recorded as a, the projection of lifting frame on the plane is recorded as b, and the projection of
fixed frame on the plane is recorded as c, wherein, the projection b coincides with partial projection a, and the projection c coincides with partial projection a. The fixed frame and the lifting frame can form the shielding, the protection effect to operating part, thereby reduce the probability of false touch operating part.
