1. A portable handheld work apparatus comprising:
a tool;
an electric motor for driving said tool;
a battery for supplying power to said electric motor;
a housing defining a battery shaft for receiving said battery;
said battery shaft having a removal opening delimited by an edge;
said battery being delimited by an end face in a removal direction of said battery in a state wherein said battery is received into said battery shaft;
said end face being delimited, in a direction radially with respect to said removal direction, at least partially by an edge region of said end face;
said edge of said removal opening projecting in said removal direction beyond said edge region of said end face of said battery received in said battery shaft;
said work apparatus having a normal state wherein said battery is removable from said battery shaft in said removal direction through said removal opening;
said work apparatus having a temporary impact state which can occur in response to an impact of said housing onto an impact surface;
said work apparatus further including a capture element;
said capture element being arranged in a region of said edge of said removal opening;
wherein, in said normal state, said capture element is configured to permit removal of said battery from said battery shaft; and,
said housing being configured to elastically deform so as to cause, in said impact state of said work apparatus, said capture element to prevent a movement of said battery out of said battery shaft because of the elastic deformation of said housing.
