IMPROVEMENT METHOD OF ASSEMBLING SHOVEL CAPABLE OF ENHANCING THE CONVENIENCE OF SHOVEL ASSEMBLY AND PREVENTING THE NECK FRACTURE, AND ENDURANCE REINFORCEMENT OF THE SHOVEL THEREBY

摘要

PURPOSE: A shovel is provided to serve to the environmental protection by using less timber and to maximize the operational income by cutting the labor costs.;CONSTITUTION: A shovel includes: an iron cap(30) which is covered on a shovel handle(20); a shovel blade(10) which is inserted into an opening which has an iron cap on the top; and a pin which interlocks the iron-cap and the shovel handle. The reason for fitting the pin into the iron-cap is to prevent the phenomenon that the shovel handle is rotated when the iron-cap and shovel blade are welded without the pin. The pin does not move anymore because the pin is welded after the pin is fitted into the shovel blade in the state that the pin holds the shovel handle and the iron-cap.;COPYRIGHT KIPO 2010
