Abstract: The invention provides a connecting structure and a Light-Emitting Diode (LED) display device having the same. The connecting structure comprises: a first pressing plate, which including a plate body and a lock sheet provided on the plate body slidably, a first mounting hole is provided on the plate body; a second mounting hole is provided on a second pressing plate; a connecting column, penetrating through the first mounting hole and the second mounting hole respectively, a lock groove matched with the lock sheet is provided on a first end of the connecting column, a force application part located below the second pressing plate is provided on a second end of the connecting column; a lifting mechanism, connected to the second pressing plate, the second pressing plate may move towards or away from the first pressing plate under an action of the lifting mechanism by operating the force application part.

Abstract: A spring loaded gripping device, having at least two hooks—one fixed and one moveable—extracts bait stations by engaging two portals on an internal cylindrical surface. The device is introduced into the station by adjusting the spring to a first retracted position, which causes the distance between the hooks do be less than the dimension defined by the distance between the portals of the bait station, thereby allowing entry of the hooks into the bait station. The spring is adjusted to a second extended position where the distance between the rods (hooks) is equal to or greater than the defined dimension. A tension is created between the portals which secures the station and allows its removal by a vertical lifting force applied to the device to which the hooks are secured.

Abstract: A swivel hook assembly includes a hook holder, a hook, which has a hook shank rotatably connected to the hook holder and a hook head for hooking, a barrel sleeved onto the hook holder and movable relative to the hook holder between a first position to close the hook head of the hook and a second position to open the hook head of the hook for hooking, and a spring member connected between the hook holder and the barrel to support the barrel in the first position.

Abstract: A bungee cord system, including, a bungee cord assembly, engaging locks, and universal anchors to safely secure, store, transport, and/or stack packages, containers and the like to surfaces. The bungee cord assembly includes an elasticized cord with first and second ends. An engaging lock assembly is fixed upon each of said first and second ends. The universal anchor includes at least one elongated member having anchor means that removably attach to the bungee cord assembly and/or the engaging lock assembly and/or a solid structure.

Abstract: Hanging hook including a hook section, a latch member, a spring, a restricting column, a ring body and a C-shaped latch ring. The hook section has a stem body a lower end of which is formed with an annular stop section. One side of the stop section is cut with a restricting split. The other side of the stop section is provided with a downward extending hook. An upper end of the stem body is pivotally connected with the ring body. An upper side of the latch member is formed with a receiving hole. A bottom face of the receiving hole is formed with a through hole. One side of the latch member is formed with a downward extending latch arm. A lower side of the restricting column is provided with a small diameter fitting post. A stop face is defined between the small diameter section and the large diameter section of the restricting column. The restricting column is formed with a central passage.
