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.

The utility model discloses even if the same puller is used in right insertion type and left insertion type open and separate insert part, and the claw part of the puller can not be easily hooked on the open and separate insert part of the insertion stick. The open and separate insert part (1, 2) of the utility model has an insertion stick (10, 60), a seat stick (20, 70) and at least one puller (40, 40a, 40b), the insertion stick has an insertion stick main body part (11, 61) and a base end insertion part (12, 62) and a claw through passage (13, 63) arranged at the base end part of the insertion stick, the claw through passage is arranged between the insertion stick main body part (11, 61) and the base end insertion part (12, 62), and is formed to allow the stop claw body (50) arranged at the puller (40, 40a, 40b) to pass through, and the passage bottom surface (13a, 63a) of the claw through passage is arranged lower than the position of the first surface (11a, 61a) of the insertion stick main body part in the thickness direction.

A combine harvester in which a plurality of dust delivery valves (30B) have a first dust delivery member (31) provided in an upper portion of a threshing chamber (16) in a state of extending in a left-right direction of the threshing chamber and being able to change a feed angle by swinging, and a second dust delivery member (32) provided at a position located on an upstream side in a rotation direction of a threshing cylinder with respect to the first dust delivery member (31) in a state of being fixed so as not to change the feed angle. A portion of a top plate (19) opposed to the second dust delivery member (32) is in an arc shape as viewed in a direction along a rotation axis center (P) of the threshing cylinder (20).
