1. A power tool, comprising:
a housing; and
a hook assembly for hanging the power tool, wherein the hook assembly has a connection shaft with a first end and a second end opposite each other, wherein the connection shaft is supported in a mounting channel of the housing, wherein the first end is disposed within a mounting hole of a holding part of the housing, wherein the second end is connected to a hook member, and wherein the hook member comprises a handle part and a hook part extending from the handle part;
wherein an elastic component is disposed between the first end of the connection shaft and a bottom of the mounting hole of the holding part of the housing;
wherein the hook member is rotatable between a first position and a second position opposite the first position, wherein the first position is a position of the hook member when in a closed state and when the power tool is in use, and wherein the second position is an initial position of the hook member when in an open state and when the power tool is not in use such that the hook member extends outward from a body of the power tool to facilitate hanging of the power tool;
wherein the handle part of the hook member is connected at a first end of the handle part to the second end of the connection shaft by a pin such that the handle part is rotatable from the first position to the second position around the pin;
wherein when the power tool hangs from the hook assembly, the hook member is further rotatable from the second position around a central axis of the connection shaft to a final position by a weight of the hanging power tool overcoming a biasing force generated by the elastic component such that a lug of the connection shaft between the first end of the connection shaft and the second end of the connection shaft slides out of a slot on an end face of the mounting channel of the housing and the connection shaft rotates under an action of the weight of the hanging power tool until a direction of the handle part of the hook member coincides with a center of gravity of the hanging power tool.
