The invention discloses a tripod device convenient to operate and an operation method thereof, and belongs to the field of tripods. The tripod device comprises a supporting column and three groups ofsupporting legs, the supporting column is hollow, a platform is arranged at the upper part of the supporting column, an upper synchronous belt wheel is erected on the platform and is coaxially and fixedly connected to a worm gear arranged on the platform, the worm gear meshes with a worm arranged on the platform, the worm is connected to a hand wheel, a bottom support is arranged at the bottom ofthe supporting column, a lower synchronous belt wheel is arranged on the bottom support, the lower synchronous belt wheel and the upper synchronous belt wheel are in transmission connection through asynchronous belt arranged in the supporting column, a sliding hoop is arranged on the supporting column and penetrates through a sliding groove formed in the side wall of the supporting column to be connected to the synchronous belt, and the supporting legs are connected to the sliding hoop through connecting rods. The tripod device has the advantages that the folding and stretching operation is quite simple, an operator does not need to bend down to operate, and therefore the manual labor of the operator can be reduced.

The invention relates to a thin metal plate laser cutting device and a discharging method thereof. The cutting device comprises a machine base, a laser cutting head, a chain wheel type conveying piece used for conveying plates and a discharging frame, and the discharging frame comprises two transverse rods and a supporting plate located between the two transverse rods; one ends of the two transverse rods are slidably connected with the two sides of the machine base respectively, and the other ends of the two transverse rods are rotatably provided with supporting rods; the supporting plate can be vertically overturned, and when the supporting plate rotates to a horizontal state, the supporting plate is flush with the upper surface of the chain wheel type conveying piece; a driving assembly used for driving the supporting plate to rotate is arranged on the discharging frame; a material collecting opening is reserved between the supporting plate and the chain wheel type conveying piece; and a separating mechanism used for separating the products from a plate frame is arranged above the material collecting opening of the discharging frame. The device further comprises a material collecting box with an upward opening and a waste material box with an upward opening, wherein the material collecting box is located below the material collecting opening, and the waste material box is located below the supporting plate. The device disclosed by the invention has the effects that the product and the plate frame are automatically separated and collected, and the working efficiency is improved.

The invention discloses an unmanned aerial vehicle undercarriage and an unmanned aerial vehicle. The unmanned aerial vehicle undercarriage comprises a mounting base, a swing rod, a first elastic piece, a lifting piece and a driving piece. The mounting base is mounted on the unmanned aerial vehicle body, and the driving piece is arranged in the mounting base; the lifting piece is arranged on the mounting base in a liftable manner and is in driving connection with the driving piece; a first end of the swing rod is rotatably arranged on the mounting base, and a second end of the swing rod can besupported on the ground; two ends of the first elastic piece are connected to the lifting piece and the swing rod correspondingly; the lifting piece has a self-locking function; and lifting motion ofthe lifting piece can drive the first elastic piece to move up and down so that the swing rod swings, folding and storage of the swing rod can be achieved, meanwhile, due to a fact that the lifting piece has a self-locking function, the lifting piece can be lifted to any position to fix the position of the lifting piece, and the first elastic piece can further play an effective damping role.

The invention provides a telescopic infusion support, and belongs to the field of infusion supports. The telescopic infusion support comprises an infusion bag hanging arm, a telescopic rod, a sleeve and a base, wherein an arc-shaped infusion bag hanging groove is formed in the front end of the infusion bag hanging arm; the upper end of the telescopic rod is hinged with the back end of the infusion bag hanging arm; the sleeve is provided with a cavity for allowing the telescopic rod to move back and forth therein; the base is arranged at the lower end of the sleeve; a first accommodating groove, which is used for accommodating the infusion bag hanging arm when the infusion bag hanging arm is folded downwards, is formed in the telescopic rod; and the base comprises a plurality of supporting legs with inner ends in sliding connection to the outer wall of the sleeve. The telescopic infusion support provided by the invention, in comparison with the prior art, can greatly diminish a space occupied by the infusion support in a folded state, and the entire infusion support is represented as a cylindrical structure after being folded, so that transportation and storage of the infusion support are facilitated.
