In order to understand the technical features and practical effects of the present invention in detail, and can be implemented in accordance with the content of the invention, the preferred embodiment shown in the drawings is further described in detail as follows: The hand-held electric chain crane provided by the present invention For a preferred embodiment, please refer to FIG. 1 to FIG. 4. The hand-held electric chain crane includes a crane body 10, a chain 20, a control box 30, an electric wire 40 and a hook 50. Among them: the crane The body 10 is provided with a structure such as a motor and a gear set. Since the crane body 10 is a common structure on the market, it will not be repeated here. The top end of the chain 20 extends into the inside of the crane body 10 to allow the chain 20 to wind. The gear set.

The control box 30 is fixed to the bottom end of the chain 20. The control box 30 is an upright rectangular body, and the control box 30 includes a hanging portion 36, a control panel 37, a back plate 38, and a rising button 31. , A lowering button 32, an emergency switch 33, a speed control button 34, and a protective cover 35, as shown in Figs. 2 and 3, the hanging portion 36 is provided in the middle portion of the control box 30 and is a straight plate body And fixed to the bottom end of the chain 20, the control panel 37 is coupled to one side surface of the hanging portion 36, and the back plate 38 is coupled to the side surface of the hanging portion 36 opposite to the control panel 37, the The up button 31 and the down button 32 are mounted on the control panel 37 of the control box 30 at intervals, and the emergency switch 33 is also mounted on the control surface of the control box 30. The speed control button 34 is disposed on the back plate 38 of the control box 30 and is a knob, and the protective cover 35 is disposed on the back plate 38 of the control box 30 and is located on the plate 37.
