PURPOSE: A coupling structure of a knife shaft cover of a pulverizing drum for a hand blender is provided to increase the durability of a part where a receiving body and a cover are coupled by welding the receiving body and the cover to the inner side of a lid. CONSTITUTION: A coupling structure of a knife shaft cover of a pulverizing drum(10) for a hand blender comprises the pulverizing drum, a lid(20), a receiving body(30), and a cover(40). A receiving space part(11) of an object to be pulverized is formed in the pulverizing drum. An upper edge part(21) of the lid is placed and fixed on an inward holding part(12) of the upper part of the pulverizing drum. An upper placing part, a middle placing part, and a lower placing part are formed in the upper edge part of the lid. An upper holding part, a middle holding part, and a lower holding part are formed in the receiving body. A through-hole is formed at the center of the lower holding part to communicate with a through-hole of the lid. The cover has an edge part(42) having fixing holes(41) corresponding to coupling holes(34) of the receiving body. |
