The invention relates to a glutamine optical probe and its preparation method and application. In one aspect, the present invention relates to an optical probe comprising a glutamine-sensitive polypeptide or a functional variant thereof and an optically active polypeptide or a functional variant thereof, wherein the optically active polypeptide or a functional variant thereof is positioned at the glutamine-sensitive polypeptide or a functional variant thereof Within the sequence of the functional variant. The present invention also relates to the preparation method of the above-mentioned probe and its application in detecting amino acids. The glutamine optical probe provided by the invention has a relatively small molecular weight and is easy to mature, has large dynamic changes in fluorescence and good specificity, can be expressed in different subcellular organelles of cells, and can detect amino acids in a high-throughput and quantitative manner inside and outside cells.

The invention provides an electric heating frying pan with an automatic vegetable cutting device, which includes a base, a heating furnace, a pot body, a mounting part and a vegetable cutting machine. The middle part of the base is disc-shaped, and one end of the base is "L" , the other end is arc-shaped and extends upwards, and one end of the base is installed with a panel for controlling the heating furnace; The eddy current furnace body has a circuit board installed inside the furnace body, a coil is arranged on the circuit board, and the panel is connected to the circuit board through wires; the pot body is placed above the furnace body, and the partition plate divides the pot body into two grids; The vegetable cutting machine includes a housing, a feeding port, a motor, a cover plate, a cutter head, a switch and a feeding port, and the inside of the housing is a hollow vegetable cutting chamber. The invention has a novel structure and a reasonable design, and integrates a frying pan, a vegetable cutter and an electric heating furnace into one body, which not only saves space, but also is easy to manage and use, and improves work efficiency.

The invention discloses a box carrying clamp. The box carrying clamp is characterized by comprising a handle, an upper shell, an upper ratchet wheel, an upper cover, a reset spring, a lower ratchet wheel, a lower shell, a push rod, a main spring, a transverse rod, a left clamping assembly and a right clamping assembly. According to the box carrying clamp, through a ratchet wheel mechanism and a connecting rod mechanism, conversion from vertical displacement to horizontal displacement is achieved, and through the ingenious design of the ratchet wheel mechanism, the whole mechanism has self-locking performance; moreover, through the design, during carrying, the weight of goods is mainly borne on the shells of the clamp, thus the internal movement mechanism is stressed little, and the size and weight of the internal mechanism are reduced; meanwhile, the ratchet wheel mechanism can well adapt to repetition in the carrying process, the using frequency is high, the connecting rod mechanism is compact in structure, mature and simple, parts are easily machined and conveniently replaced, and the economical performance and reliability are greatly improved.
