The invention provides an aeroponic virus-free seed potato breeding method and equipment. The breeding method includes the following steps: equipment cleaning and disinfection, greenhouse disinfection through a smoke drug, seedling hardening, planting and atomization, illumination and temperature management, seedling shedding, overgrowth and lodging control, nutrient solution concentration management, nutrient solution pH value management, nutrient solution temperature management, pest and disease damage prevention, and harvesting. The breeding equipment includes cultivation tanks, cultivation plates, a nutrient solution, a solution storage container, a solution delivery pipe, atomization nozzles, a circulating pump, and a nutrient solution return pipe, wherein each cultivation tank is a cuboid tank of which the length is much larger than the width, the inner surface of each cultivation tank is painted black, the outer surface of each cultivation tank is painted silvery grey, and each cultivation tank is supported from the ground through a bracket; the solution storage container is an underground solution storage pool, a temperature sensor is arranged in the solution storage pool, and a nutrient solution cooling thermolator is arranged outside the solution storage pool. The method provided by the invention can reduce the seedling time, prolong the collection period, and increase the yield; the number of stolons is increased, so as to lay a foundation for a higher yield of virus-free seed potatoes. The equipment provided by the invention is convenient to manage, can save energy, and runs reliably.

The invention provides a supporting and adjusting device for communication equipment and relates to the field of communication equipment. The supporting and adjusting device comprises a base. A firstfixed column is fixedly mounted on the left side of the top of the base. A second fixed column is fixedly mounted on the right side of the top of the base. A threaded shaft is mounted between the first fixed column and the second fixed column. A motor is fixedly mounted on the right side of the second fixed column. A rotating shaft of the motor is in transmission connection with the threaded shaft. The surface of the threaded shaft is sleeved with a lower fixed seat. According to the supporting and adjusting device for the communication equipment, through the motor, the motor can drive the threaded shaft to rotate and drive an upper fixed seat to be adjusted on the threaded shaft, so that a connecting rod can be driven to extend and contract, the height of a supporting table can be adjusted, the height of a supporting device can be conveniently adjusted, and the use is convenient; and the angle of the communication equipment can be conveniently adjusted through the rotating shaft, so that a user can conveniently adjust the inclination of the device according to the comfortable posture of the user, the shoulder fatigue can be avoided, and the comfort of the user can be greatly improved.

An apparatus for adjusting a tilt angle of a vertically positioned antenna on a pole that includes a top mounting assembly formed by a first link and a second link, the first and second link each including a top edge and a bottom edge, the top edges of the first link and the second link are pivotally connected together by a first hinge such that the second link is rotatable about the first hinge in relation to the first link to adjust an angle between the first link and the second link.

The invention relates to a reading newspaper rack, which comprises a rectangular bracket of a newspaper, two main fixed pieces on the bracket for fixing the newspaper and a support piece connected with the bracket. The reading newspaper rack is characterized in that each main fixed piece is a rectangular spring clamp of which the length of a clamping part is equal to the length of a centre joint of the newspaper and is arranged at the center of the bracket. After the rectangular spring clamps are used, the centre joint of the newspaper can be powerfully clamped, the straightness of the newspaper can be guaranteed, the newspaper is conveniently read, and the spring clamps are longer in service life. The spring clamps are clamped and embedded in a groove at the center of the bracket and can be independently withdrawn, so that the newspaper can be conveniently assembled and disassembled. The newspaper can be further fixed by two short rectangular spring clamps arranged at the top end of the bracket. Furthermore, the angle and the height of the bracket can be adjusted, so that the reading newspaper rack is more comfortable to use, and more in application occasions.
