The invention relates to the field of refrigerator equipment, in particular to a refrigerator of which a shelf can be adjusted in height. The refrigerator comprises a door, guide rails, a plurality of adjusting grooves, the shelf and limiting grooves in the shelf, wherein the guide rails are vertically formed on the door, and the adjusting grooves are formed in the guide rails. The shelf is assembled on the guide rails through the limiting grooves and can move up and down. The shelf is provided with guide parts, limiting blocks and resetting devices. The resetting devices drive the limiting blocks to enter the adjusting grooves along the guide parts so that the shelf can be supported at any height. Manipulation pieces are further arranged in the shelf. The manipulation pieces and the limiting blocks mutually push tightly through slopes to be in mutual linkage. The limiting blocks can be controlled to recede out of the adjusting grooves by controlling the manipulation pieces by hand so that the shelf can be moved to a new height at will. According to the refrigerator, the height of the shelf can be quickly adjusted without taking out the shelf, so that the problem that a traditional refrigerator door shelf is inconvenient to operate is solved. Besides, the refrigerator is simple in structure and convenient to operate.

The invention discloses a chemical device inspection maintenance teaching device which comprises an operating console. A chemical device body is arranged on the top side of the operating console.

One end, which is away from a fixed block, of each adjusting rod is slidably arranged ina slide groove. According to the invention, a number of operating consoles can be stably combined and arranged, which facilitates the teaching of single or multiple chemical devices; and the height of the operating console can be adjusted, which facilitates combination installation, facilitates the movement of the operating console and meets various height operating demands.

The invention discloses a stable and steady folded type camera support and belongs to the technical field of camera supports. The folded type camera support solves the problem that an existing devicecannot adjust the inclination angle of a camera. The camera support is characterized by comprising a support body, a lifting sleeve, a supporting column and a horizontal installing base. The supporting column is fixedly connected above the support body. The lifting sleeve is arranged on the upper portion of the supporting column in a sleeving manner. The horizontal installing base is fixedly connected to the upper end of the lifting sleeve. A supporting plate is fixedly installed on the upper surface of the horizontal installing base. The supporting plate is provided with a camera clamping base used for installing the camera. An angle adjusting mechanism is arranged on the right side of the camera clamping base. According to the folded type camera support, the inclination angle of the camera can be adjusted flexibly, meanwhile, the height and horizontal position of the camera can be adjusted stably, the photographing requirements in different environments can be met, meanwhile, a rolling wheel is convenient to store, and the support is flexible to move and stable in supporting.

The invention relates to the technical field of vegetable planting racks, in particular to a height-adjustable vegetable planting rack. The height-adjustable vegetable planting rack comprises a bottomplate, a motor is fixedly connected to one side of a box which is fixedly connected to the upper surface of the bottom plate, and one end of an output shaft of the motor penetrates the box and is rotationally connected with a bidirectional screw rod. Two sides of the outer surface of the bidirectional screw rod are in threaded connection with moving blocks respectively, slide sleeves are fixedlyconnected to lower ends of the two moving blocks respectively, and a guide rod is fixedly connected to the inner lower portion of the box. Connecting rods are hinged to two sides of the upper surfaceof each of the moving blocks, a planting plate is connected to upper ends of the four connecting rods, and a plurality of planting pots are uniformly placed on the upper surface of the planting plate.Mounting rods are fixedly connected to four corners of the upper surface of the planting plate respectively, and a humidifying mechanism is fixedly connected to upper ends of the four mounting rods and positioned above the multiple planting pots. The height-adjustable vegetable planting rack has advantages of simplicity in adjusting operation, convenience in use and high practicality.

The invention discloses a side drilling device for an electronic connector. The side drilling device comprises a base, a telescopic moving mechanism, a clamping plate and a driving mechanism. According to the side drilling device, through rotation of a driving cylinder, moving screw rods at the two ends of the driving cylinder are driven to move, so that a moving plate, a sliding clamping rod, a moving column, floating rods, transverse plates and a clamping plate are driven to transversely move together, and the clamping distance can be adjusted according to electronic connectors with different diameters, and driving screw rods are driven to rotate up and down in positioning threaded cylinders to drive the transverse plates and the floating rods to move up and down, so that the clamping height is changed, the height position of a drilled hole is adjusted, operation is convenient, and double movement adjustment of transverse movement and longitudinal movement can be achieved.
