The disposable restraint strap is small in size, light in weight, reliable in restraint and convenient to carry, and the problems that metal handcuffs are large in weight and size, inconvenient to carry and have escape risks can be solved.

The utility model relates to a technical field of hanger, concretely is a socket type reinforced concrete pipe hanger, including gallows, the lifting lug that sets in the middle part of gallows upside, the load bearing chain that sets in the both ends of gallows downside respectively, and the C type lifting hook that is connected with two load bearing chain lower end respectively and symmetrical layout, still including the unhooking tensioning mechanism that sets in the inside upside of two C type lifting hooks, the telescopic drive mechanism that sets in the middle part of gallows downside, and the inside support clamping mechanism that sets in the downside of two C type lifting hooks respectively and symmetrical layout, the output of telescopic drive mechanism is connected with the upside middle part transmission of unhooking tensioning mechanism, this hanger can form reliable restraint from inside and outside two sides through the cooperation of inside support clamping mechanism, unhooking tensioning mechanism and telescopic drive mechanism, eliminates the hidden danger of pipe body slip in the hoisting process, improves the operation safety.

The invention relates to the technical field of household appliances, and discloses a food processor which comprises a cup base assembly. The cup body assembly is rotationally connected with the cup base assembly; the rotation stopping assembly comprises a containing groove, a rotation stopping structure and a control structure, the rotation stopping structure has a rotation stopping state in which the rotation stopping structure is inserted into the containing groove and a receding state in which the rotation stopping structure is pulled out of the containing groove, and the control structure is suitable for forcing the rotation stopping structure to be switched between the rotation stopping state and the receding state; the rotation stopping structure comprises a spring bolt base and a spring bolt formed at the bottom of the spring bolt base, a guide cavity extending in the movement direction of the control structure is formed in the spring bolt base, and the control structure is arranged in the guide cavity in a penetrating mode. According to the food processer, only one action of rotating the cup body assembly is needed when the food processer is installed, disassembly can be completed only by pressing the button and rotating the cup body assembly at the same time, so that a user is prevented from mistakenly disassembling the food processer in the operation process, the user can conveniently clean the lower portion of the cup body assembly, and food residues are prevented from being accumulated at the cup bottom and going bad.

The application provides a high altitude balloon launching method and a composite high altitude balloon. The high altitude balloon launching method comprises the following steps: putting the high altitude balloon into a windproof air bag, and connecting the high altitude balloon, a cable and a gondola in sequence; arranging winch pull ropes on the periphery of the windproof air bag, and arranging cutters on the winch pull ropes respectively; filling air into the windproof air bag and filling helium into the high altitude balloon, and controlling the pressure difference between the windproof air bag and the high altitude balloon within a preset pressure difference range after the filling is completed; releasing the windproof air bag and synchronously releasing the winch pull ropes; cutting the winch pull ropes by using the cutters when the distance between the gondola and the ground is greater than a first safety height; and detaching the windproof air bag to make the windproof air bag separate from the high altitude balloon when the distance between the gondola and the ground is greater than a second safety height. The high altitude balloon launching method and the composite high altitude balloon provided by the application aim to solve the problem that the wind resistance of the high altitude balloon is weak and the high altitude balloon is easy to be damaged in the launching process in the prior art.

The utility model relates to a connecting node of a prefabricated rail top air duct and a middle plate, which comprises a hanging bar pre-buried in a hanging wall, the upper end of the hanging bar penetrates out of a reserved hole of a main body middle plate and is screwed with a fixing nut, and a clamping ring base plate is clamped between the bottom of the fixing nut and the top of the main body middle plate. The periphery of the hanging bar between the top of the hanging wall and the bottom of the main body middle plate is filled with a macromolecular foaming fixed template; grouting materials are injected among the hanging bar, the reserved hole of the main body middle plate and the macromolecular foaming fixed template; the clamping ring base plate comprises two hinged steel base plates, semicircular through holes are formed in the middles of the butt joint faces of the two steel base plates, the hanging bar penetrates through a circular hole formed by the two semicircular through holes, and the two steel base plates are connected through a connecting gasket, a fixed screw and a movable screw. According to the utility model, the rail top air duct and the main body middle plate can be stably connected; traditional formwork erecting and dismantling are not needed during grouting material filling, time is saved, and the construction progress is accelerated; the joints can be adjusted up and down, and the assembling precision and the mounting quality of the rail top air duct are improved.

The application discloses a SAM2 small sample segmentation method based on semantic-visual double memory fusion, constructs semantic query memory, visual query memory and query related support visual memory, fuses the semantic query memory and the visual query memory through a memory refinement module guided by the query related support visual memory, and combines SAM2 dense matching and decoding module end-to-end training.
