Abstract: A tool display device includes a body having a top portion for being hanged on a wall. A mediate portion is connected to the top portion, and a bottom portion is connected to the meditate portion. A cylindrical connection portion is connected to the bottom portion. A slot is defined through the connection portion and extends from the top of the connection portion and ends before the distal end of the connection portion. An opening is defined in the top of the connection portion and communicates with the slot. The slot divides the connection portion into a left part and a right part. The right part has a protrusion extending from the outside thereof. An restriction member is connected between the mediate portion and the right part. A socket is mounted to the connection portion and can only be removed from the connection portion when the restriction member is cut.

Abstract: A blow gun includes a body with first and second paths, a trigger, a control unit, a first spring, a second spring and a first pin. The control unit includes a control member, a bar, a seal ring, an end member, a collar and a fastening member. The control member is received in the first room and has a slot located corresponding to the first hole. The end member is connected to the control member and the seal ring is mounted to the end member to seal the communication between the first and second paths. The first spring is biased between body and the control unit. The second spring is biased between the body and the trigger. The first pin extends through the first hole and is movable in the slot of the control member. The two springs share the force applied thereto to have a long service life.
