[0002] Earthwork excavation is a key process in the early stage of the project and even during the construction process. Before construction, it is necessary to study and select the excavation method based on the scale and characteristics of the project, natural conditions such as topography, geology, hydrology, and meteorology, construction diversion methods and project progress requirements, construction conditions, and possible construction methods. Open excavation includes full excavation, partial excavation, layered excavation, and segmented excavation. After the construction of a building, some narrow spaces will be generated. When excavating earth in a narrow space, machinery cannot enter, and excavation can only be done manually with a shovel. For example, the Chinese utility model patent with application number CN202321992063.0 discloses an earth excavation device, including a first earth excavation shovel handle, the bottom end of the first earth excavation shovel handle is threadedly connected with a first threaded connection port, and the bottom of the first threaded connection port is fixedly connected to a water tank, and the side of the water tank is integrally connected with a water inlet, the bottom of the water tank is connected to a water outlet nozzle, and a loosening needle is arranged on the side of the water outlet nozzle, a second threaded connection port is arranged on the side of the first threaded connection port, and a foot plate is fixedly connected to the outside of the second threaded connection port, a convex point is integrally connected to the top of the foot plate, and the bottom of the foot plate is fixedly connected to the earth excavation shovel head; the above excavation device is convenient for use in places where a small area of ​​earth excavation is required.

[0003] However, the temperature is low in winter, and a frozen layer will form on the upper layer of the soil, making manual excavation difficult. Since the soil is hard, it is easy for the shovel head to be clamped, making it impossible to pull out the shovel head. It is more laborious to lift the excavated soil. The method of spraying water to loosen the soil by the above-mentioned excavation device is not applicable in winter. Utility Model Content

[0010] Furthermore, a universal ball is connected to the end of the piston rod of the electric telescopic rod, and the end of the piston rod of the electric telescopic rod is connected to the pressure plate through the universal ball.

[0011] Compared with the prior art, the utility model has the following technical effects:

[0012] 1. The utility model can quickly dig up the frozen soil layer by hammering the shovel head with an electric pick. When the shovel head is clamped by the soil, the electric telescopic rod is moved to the end of the fixed frame away from the electric pick with the cooperation of the slide seat and the slide slot. The electric telescopic rod is parallel to the electric pick.

A plug-in rod 12 is welded on the top of the shovel head 4, and the plug-in rod 12 is plugged into the plug-in groove 11. An annular groove 13 is provided on the top surface of the plug-in rod 12. A locking screw 14 is threadedly connected to the bottom surface of the electric pick 1. After the plug-in rod 12 is matched with the plug-in groove 11, the locking screw 14 is matched with the annular groove 13.

[0024] It should be noted that the shovel head 4 is connected to the plug-in slot 11 through the plug-in rod 12, and the locking screw 14 is rotated at the same time. The end of the locking screw 14 is plugged into the annular groove 13, which can fix the shovel head 4 and also realize the rapid replacement of the shovel head 4.
