The invention discloses a combined aircraft composed of a fixed wing and an electric multi-rotor wing. The combined aircraft comprises a group of electric multi-rotor wing power systems and a general controller; a fixed wing power system and the electric multi-rotor wing power systems are independent in structure; the general controller comprises a fixed wing control system and an electric multi-rotor wing control system for controlling the electric multi-rotor wing power systems to work; the general controller is further used for controlling the fixed wing control system and the electric multi-rotor wing control systems to work independently or work cooperatively; and a rotor wing rotary plane of the electric multi-rotor wing power system is parallel to a central axis of a machine body. The combined aircraft disclosed by the invention can freely convert between two flying modes, can vertically ascend and descend and fly as a helicopter and can also ascend and descend and fly as a fixed wing airplane; and the flying of the combined aircraft can be realized by using a mode of the mixing work of the two power systems in ascending, descending and flying processes.

The invention relates to the technical field of riding suitcases, and in particular relates to a folding riding suitcase. The folding riding suitcase comprises a box body, idler wheels, a riding frontfork and a riding front wheel; the idler wheels are at the bottom of the box body, and used for supporting the box body to roll; the riding front wheel is below the riding front fork; a swing arm mechanism performing rotary folding towards the bottom of the box body is installed on the box body; the riding front fork is installed on the swing arm mechanism; the riding front fork is rotatably folded to the bottom of the box body through the swing arm mechanism; and a rotary folding mechanism is on the riding front fork, and used for folding the upper section of the riding front fork protrudingout of the bottom of the box body to the bottom of the box body in a rotary folding manner. The folding riding suitcase in the invention has the benefits that: compared with the riding suitcase thatthe riding front fork is parallel and telescopic, the riding front fork and the riding front wheel are rotatably folded to the bottom of the box body; the hiding performance is good; furthermore, theinternal storage space of the suitcase becomes large; simultaneously, the folding riding suitcase in the invention can be converted between a riding state and a hand pushing state conveniently, freelyand randomly; and thus, the folding riding suitcase is convenient for users to travel.

The present invention provides a piece of dual-purpose tableware. A spoon is disposed at the other end of an ordinary fork. When the dual-purpose tableware is used, and switch between the spoon and the fork can be rapidly and freely completed. Two kinds of tableware are combined into an integral body at the same time, and the expenditure is saved.

The invention discloses a connecting device and a connecting method between a submarine optical cable and a land optical cable. The connecting device comprises a cover plate, a shell, a long screw, a fiber fusion tray, a cone seat and a land cable clamp. One side of the cover plate is a plane, and the other One side is provided with a circular concave area and a circular groove with the center as the origin, the shape of the shell matches the cover plate, a circular edge is provided at the open end of the shell, and a plurality of hollow cylinders are provided on the cylindrical surface, One of the hollow cylinders is fixedly connected to the submarine optical cable through the cone seat, and an inner cone and an outer cone are arranged between the submarine optical cable and the cone seat, and the other hollow cylinder is fixedly connected to the land optical cable through a land cable clamp; There are several splice trays, and the splice trays are fixed by long screws. The device can effectively clamp the armored steel wire, so that the submarine optical cable does not come out and does not break under the condition of severe tension; was pulled out.

The invention provides a dual-use table ware. The other end of a common fork is provided with a spoon. During the use, switch between the fork and the spoon can be quickly and freely achieved; and two tableware articles are combined into one, so cost can be reduced.

The invention relates to the crossing field of diffraction optics and optical fiber optics, in particular to an optical fiber spatial transmission mode converting device and a converting method based on an optical phased array under free and flexible programmed control. According to the optical fiber spatial transmission mode converting device, two sets of optical fiber coupling interfaces, calibration beam expanders, beam splitters and reflectors are arranged in symmetry with an optical phased array acting surface or the perpendicular surface of the optical phased array acting surface, then a 4-f system is formed, the optical phased array 5 is arranged on the Fourier plan of the 4-f system, and thus the converting device is formed. The invention further discloses a converting method using the converting device. Free and flexible conversion of optical fiber spatial transmission modes is achieved.

The invention discloses a portable refrigerating device and a portable medical cold compress device. The portable refrigerating device comprises: a portable box body, a refrigerating storage cavity arranged in the box body for accommodating items to be refrigerated; and a refrigerating system and a control system; A rechargeable battery for power supply arranged in the box and connected with the refrigeration system and the control system; a charging interface connected with the rechargeable battery; a portable refrigeration device and a portable medical cold compress provided by the present invention The device is small in size and easy to carry. The portable refrigeration device can provide cold drinks conveniently. The portable medical cold compress device adopts the intermittent cold compress system that meets the needs of joint injury treatment, and can perform intermittent cold compress on the injured part in time, which greatly improves the cold compress effect. Effect. The intermittent cold compress system includes three straps for different cold compress parts, which can be freely switched according to needs during use, which is flexible and convenient.
