Cutter sharpener

A cutter sharpener, comprising:

• a housing, a height adjusting mechanism and a cutter clamping mechanism mounted on the housing, and a grinding mechanism rotatably connected to the height adjusting mechanism, wherein the housing comprises a first mounting location, the height adjusting mechanism is movably connected to the first mounting location, the height adjusting mechanism comprises a lifting body, a knob, and a screw rod fixedly connected to the knob;
• and the lifting body can move up and down relative to the first mounting location;
• the cutter sharpener further comprising a degree indicating mechanism fixedly connected to the lifting body;
• wherein the lifting body is internally provided with an internal thread matched with the external thread of the screw rod;
• when the knob is rotated to drive the screw rod to rotate, the lifting body moves up and down along an axial direction of the screw rod in the first mounting location, an axial direction of the knob is parallel with a moving direction of the lifting body;
• wherein the cutter sharpener further comprises a connecting mechanism, and the grinding mechanism is rotatably connected to the lifting body through the connecting mechanism;
• wherein the degree indicating mechanism comprises a degree indicating plate, and scales of the degree indicating plate are distributed circumferentially, the connecting mechanism being connected to the lifting body through a first connecting shaft, and an axis of the first connecting shaft passing through a center of a circle where the scale of the degree indicating plate is located;
• the first connecting shaft is connected with the degree indicating plate and the lifting body;
• the degree indicating plate is directly fixed connected with the lifting body;
• wherein the connecting mechanism comprises a first connecting member and a second connecting member rotatably connected to the first connecting member, a free end the first connecting member is opposite to a free end of the second connecting member, rotational directions of the first connecting member and the second connecting member are perpendicular to each other, and the first connecting member is coaxially and rotatably connected to the first connecting shaft;
• wherein the first connecting member is extended to form a pointer thereon for indicating the scale on the degree indicating plate which represents an angle of the grinding mechanism with respect to a horizontal plane, and an extending direction of the pointer is in opposite with an extending direction of the free end of the second connecting member;
• wherein the first connecting member is rotatably connected to the second connecting member through a second connecting shaft, an extension line of the pointer of the first connecting member forms a first plane with the axis of the first connecting shaft, a rotational plane of the second connecting member is a second plane, the first plane is parallel to or coincident with the second plane, and an axis of the second connecting shaft is perpendicular to the first plane and the second plane.
