The utility model provides a grass mowing executing mechanism and a grass mowing machine, and belongs to the technical field of grass mowing equipment. The mounting shell is used for mounting one of a grass mowing blade or a grass mowing rope, a connecting clamping groove is formed in one of the mounting shell and the rotating head, a connecting buckle is arranged on the other one of the mounting shell and the rotating head, the connecting clamping groove and the connecting buckle are fixed in a clamped mode, meanwhile, the connecting clamping groove and the connecting buckle can be separated, and the rotating head can rotate in the axial direction of the rotating head. One of the rotating head and the mounting shell is provided with a mounting part, a mounting cavity is formed in the mounting part, an abutting elastic piece is arranged in the mounting cavity, one end of the abutting elastic piece abuts against the bottom wall of the mounting cavity, and the other end of the abutting elastic piece abuts against the other one of the rotating head and the mounting shell; the device has the advantages that the abutting elastic piece can be in a compressed energy storage state, that is, the abutting elastic piece exerts continuous pre-tightening force on the mounting shell and the rotating head, the connecting buckle and the connecting clamping groove are kept in close contact through the pre-tightening force, and the risk of loosening or disengagement caused by vibration or external force is reduced.

The utility model provides a kind of blade adjusting mechanism and bean grinder, it is related to the field of grinding equipment.The spacing between fixed grinding wheel and movable grinding wheel of bean grinder is adjusted, and adjusting mechanism includes: adjusting ring, its movable setting is in rack top;Driving ring is connected in the inside of adjusting ring, and its inside is provided with the annular limiting portion of inward bulge;First limiting part, abut on limiting portion, and rotationally set in the outside of driving shaft;And the top of first limiting part is in abutment with the limiting ring embedded in the outside of driving shaft;Guide sleeve, fixed in the inside of rack and with adjusting ring between there is adjusting spacing, its top inside is with the lower outside of driving ring screw connection, its bottom is embedded with second limiting part;Second limiting part rotationally set in the outside of driving shaft, and second limiting part and movable grinding wheel between abutment have elastic member, and elastic member set in the outside of driving shaft.This application can accurately adjust the spacing between two grinding wheels, compensate tolerance, satisfy different coffee grinding needs.
