| description | The invention relates to the technical field of electric tool parts, and provides an electric pick shovel which comprises a pick body and a pick palm which are connected in a forging and pressing mode, an opening is formed in the lower end of the pick body, the center of the upper end of the pick palm is embedded into the opening and matched with the opening, a plurality of holes are formed in the center of the upper end of the pick palm, and the holes are communicated with the opening. The portions, on the two sides of the opening, of the pickaxe body permeate into the holes through high-temperature forging and pressing, and the external connecting position of the pickaxe body and the pickaxe palm is fixed in a welding mode. According to the electric pick shovel provided by the invention, the hardness and the structural strength are greatly improved, the use is convenient, the durability is realized, the service time can reach 2-5 times of that of an electric pick shovel on the market, and the cost is low.
