Detailed Description
The present invention will be described in detail with reference to specific examples.
Example 1: as shown in fig. 1, 2 and 3, an upper cover structure of a hand-operated coffee bean grinder comprises a main body 4, an upper cover 2 and a main shaft 3 positioned in a cavity of the main body. The upper part of the main body 4 is provided with an upper cover, the upper cover 2 is of an independent structure, the upper cover is provided with threads which can be screwed with the opening of the main body, the middle of the upper cover 2 is provided with a cover hole 21, the main shaft 3 passes through the cover hole, and the head 31 of the main shaft is positioned outside the cover hole 21; one end of the rocker arm is provided with a rotating head 1 which can drive the main shaft to rotate, the rotating head is sleeved at the head of the main shaft, and the rotating head can be detached from the head of the main shaft.
The lower end face of the head of the main shaft is provided with a turning hole matched with the head 31 of the main shaft in shape, and the turning head 1 is sleeved on the head of the main shaft through the turning hole. The head 31 of the spindle is non-circular in cross-section.
The middle of the upper cover is provided with a concave 22 which is sunk inwards, the bottom of the concave is provided with an inner hole step 23, and the cover hole 21 is arranged on the inner hole step. The rotary head extends into the recess, the surface of the upper cover corresponding to the lower end surface of the rotary head is the inner hole step, the lower end surface of the rotary head 1 is contacted with the inner hole step, and the top 101 of the rotary head hole is not contacted with the top 32 of the main shaft.
The lower end face of the rotary head 1 is in contact with the inner hole step and the lower end face of the rotary head, the top of the rotary head hole is not in contact with the top of the main shaft, and therefore when the rocker arm or the rotary head is impacted by external force, the bearing of the main shaft in the main body is impacted through the rotary head and the main shaft, the inner structure can be protected, and the service life of a product is prolonged.
