Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, and more specifically to a lithium battery type electric pick. Background Art

[0002] In various working conditions such as infrastructure construction, municipal engineering maintenance and emergency repair, heavy-duty electric picks are commonly used as tools, playing an important role in heavy-duty operations such as demolition of concrete and asphalt pavements and stone excavation. Most of the existing heavy-duty electric picks are designed to be connected to a household AC power supply (220V), which will encounter great limitations in outdoor construction. For example, in municipal emergency repairs or water pipe breaks, small-area concrete and asphalt ground collapses, stone removal, mountain honey collection, emergency rescue and other occasions, users often face problems such as difficulty in power connection, inconvenience in mobility, and power supply line restrictions.

[0003] In order to solve the problem of power connection, it is common to use generators. However, generators are not only heavy and inconvenient to carry, but also noisy when running and need to be refueled frequently, which brings additional labor intensity and inconvenience to on-site workers. In addition, although traditional mobile power supplies can provide portability to a certain extent, large-capacity mobile power supplies are often large in size and weight, making them difficult to move. Moreover, when the wires are pulled far away, the power transmission efficiency will decrease, which cannot meet the needs of high-efficiency work of heavy electric picks.

[0004] Although the existing lithium-ion small electric picks / hammers are light and easy to carry, their low voltage (21 volts) design makes the energy output insufficient and difficult to handle high-load operations, so they are far less efficient than heavy electric picks. These limitations significantly affect work efficiency and operational convenience, so there is an urgent need for a new type of portable and efficient heavy electric pick. Utility Model Content
