A fastening device is provided. The fastening device is composed of a case, a spool, a knob and a locking unit. The case includes a mounted portion. The spool is disposed at the case and a lace is wound around the spool. The knob includes an engaged portion for engaging with the mounted portion such that the knob is coupled to the case. The locking unit is coupled to the knob and is driven by the knob. The locking unit is switched from a first position to a second position by rotating the knob relative to the case. When the locking unit is at the first position, the locking unit is coupled to the spool to prohibit the spool from rotating toward a loosening direction. When the locking unit is at the second position, the spool is allowed to be rotated toward the loosening direction.

The invention discloses a device for transferring neodymium iron boron blank. The device comprises a material arranging box, a concave baffle and a convex baffle. The concave baffle is located in thematerial arranging box and is arranged parallel to a side plate of the material arranging box. A concave portion is formed in one end of the concave baffle in the length direction. The convex baffle is located in the material arranging box and perpendicular to the concave baffle, and a convex portion passing through the concave portion is arranged at the end, adjacent to the concave baffle, of theconvex baffle in the direction away from the convex baffle. When the concave baffle moves relative to the convex baffle in the length direction of the convex portion until the plate surface of the concave baffle abuts against the neodymium iron boron blank, and the convex baffle moves relative to the concave baffle in the length of the concave portion until the plate surface of the convex baffleabuts against the neodymium iron boron blank, the concave baffle and the convex baffle are fixed into the material arranging box separately through a set of fastening assemblies. The device for transferring the neodymium iron boron blank has the effects of reducing the proportion of edge breakage of the neodymium iron boron blank during transportation and improving the efficiency of material arranging.

A fluid-filled vibration damping device including: a rubber elastic body elastically connecting a first and second mounting member and partially defining a pressure-receiving chamber filled with a non-compressible fluid; a flexible layer partially defining an equilibrium chamber filled with the non-compressible fluid; an orifice passage permitting a fluid communication between the pressure-receiving chamber and equilibrium chamber; and a cushion surface situated opposite to an opening of the orifice passage to the pressure-receiving chamber in a first direction of flow of the fluid into and out of the opening, with a predetermined distance therebetween, while extending in a second direction approximately perpendicular to the first direction.

The invention provides an underwater emergency rescue system and an underwater rescue method based on the rescue system, relates to the technical field related to underwater rescue equipment, and aims to solve the problems that in the prior art, a traditional sunken ship chain type salvage method needs large rescue equipment and is low in rescue speed. The underwater emergency rescue system comprises hoisting equipment and an underwater welding device, wherein the underwater welding device is used for welding a stud on a sunken ship, a hanging ring is installed on the welded stud, the hoisting equipment is installed on a working ship or a coast, and a cable is connected with the hoisting equipment so as to hoist the sunken ship through the hoisting equipment. Underwater stud welding is adopted, a force exerting gripper is rapidly welded to an object to be fished, hoisting as soon as possible is facilitated, and rapid underwater emergency rescue is achieved.

A fastening structure including a base pillar, a pair of elastic arms, and a top pillar is provided. The base pillar is assembled to an object, the elastic arms are connected between the top and the base pillars, and a gap is provided between the elastic arms. The top pillar is adapted to stretch or compress the elastic arms when an external force is exerted to reduce or expand the gap. The top pillar and the elastic arms pass through a through hole of a connector when the elastic arms are stretched to reduce the gap to make the connector contact the base pillar. After the force is removed, the gap between the elastic arms is restored to fasten the fastening structure between the elastic arms and the base pillar in a floating state. An electronic assembly and an operating method of the fastening structure are also provided.
