Abstract: An anti-theft display card structure comprises a hanger portion, a connection portion and a stopper. The hanger portion has a fixing seat at an end thereof for the connection portion to clamp thereto and the fixing seat has a stop surface at each of two sides thereof The hanger portion has a clamping slot for receiving and securing the stopper. The clamping slot includes a receiving slot with a larger slot size, an engaging slot with a smaller slot size, and an arcuate seat formed between the receiving slot and the engaging slot. The arcuate seat is an engaging structure formed on two sides of the receiving slot, having arcuate surfaces, and tapering in one direction from the receiving slot towards the engaging slot, so that the stopper can only be pushed into the engaging slot from the receiving slot for being secured against theft.

Abstract: A quick switching hand tool comprises a driving head having a ratchet teeth portion; a control device having a control rod; the control rod being installed with a driving block which is interacted with a buckle unit; and the buckle unit is engageable to the ratchet teeth portion. When the control rod is pressed, the control rod will drive the driving block to rotate so that the buckle unit shifts with the driving block so as to switch the restoring direction of the driving head. Furthermore, in another design, the buckle unit has two buckle teeth blocks. Each buckle teeth block is pivotally installed to the driving head and the buckle unit is engageable to the ratchet teeth portion; an outer end of the driving block has an resisting rib for controlling positions of the buckle teeth block.

Abstract: A burglarproof socket exhibition assembly, comprises a head; a body installed to a lower end of the head; the body having a cylindrical structure; the body having a hollow channel; a front side of the hollow channel of the body having a first rib and a rear side of the hollow channel of the body having a second rib; the first rib having a position higher than that of the second rib; and each of two sides of the front end of the body having a protrusion; the two protrusions being at two opposite sides of the hollow channel, each of two sides of the rear end of the body having a protrusion; and the two protrusions being at two opposite sides of the hollow channel. It is very difficult to take the socket from the burglarproof socket exhibition assembly so that it has the effect of burglarproof.

Abstract: A socket retaining assembly comprises a retaining assembly having a seat, and a retaining post; the retaining post being installed at an upper end of the stopper; an outer periphery of the retaining post being installed with a confining projection and a plurality of trenches; a combination unit including a rotating assembly and a push unit; the stopper serving to confine the rotation range of the combination unit; the rotating assembly has a C ring at a lower end thereof; two ends of an opening of the C ring being concaved inwards so as to form with inward projections; an upper side of the C ring being installed with a rectangular protrusion unit; an interior of the protruding block being formed with a rectangular receiving groove; and the push unit being installed in the receiving groove of the protruding block.

Abstract: A returning assembly of a spanner includes a driving portion having a receiving space for receiving a driving head, a switch unit and an ejecting unit having a truncated conic shape; a radial direction of the driving head having a slightly inclined buckling surface; the buckling surface and an inner wall of the receiving space being formed with a semilunar buckling space for receiving the ejecting unit; the ejecting unit serving for controlling the returning directions of the driving head. A round cylindrical positioning portion extends from the larger end of the truncated conic ejecting unit. The driving head has a driving block which are arranged at an axial direction of the driving head for installing a socket or other driving assembly. A switch unit is installed in the driving head. The switch unit has a control end projected from the driving portion and a resisting end.

Abstract: A hollowed socket comprises a driving portion and an engaging portion; an outer side of the driving portion having a receiving groove; an elastic sheet being installed in the receiving groove; and a free end of the elastic sheet having a positioning block. An inner space of the driving portion is communicated to the receiving groove. The elastic sheet has a shape like “8” and one end of the elastic sheet is a fixing end which is fixed to the receiving groove. The elastic sheet is fixed to the receiving groove by using a fixing unit. The elastic sheet is tightly engaged to the receiving groove. An inner space of the driving portion is communicated to an inner space of the engaging portion.

Abstract: A ratchet tool includes a bar movably received in an operation space defined between an inner periphery of a cylindrical space in the head of the ratchet tool and a flat surface defined in an outer periphery of the cylindrical body of the driving mechanism. The bar is pushed toward two wedge-shaped areas in the operation space to control the effective direction of the driving mechanism. The bar is pushed to either one of the two wedge-shaped areas by two positioning units which are movably received in the cylindrical body. The tow positioning units are shifted alternatively by a shifting member mounted on the rod the quick release device which controls a bead for securing a socket mounted on the driving member of the driving mechanism. The efficient directions and the socket are both controlled by one-time operation of the quick release device.
