The invention discloses a conveniently adjusted unmanned aerial vehicle camera support which comprises an unmanned aerial vehicle bottom plate. The lower end of the unmanned aerial vehicle bottom plate is fixedly connected with a positive and negative rotation motor, the end of an output shaft of the positive and negative rotation motor is fixedly connected with a connecting disk, two sides of thelower end of the connecting disk are fixedly connected with hanging racks, a camera is fixedly connected between the hanging racks through a fixing shaft and a bearing, one side of each hanging rackis fixedly connected with an adjusting motor, and an output shaft of the adjusting motor penetrates the hanging racks and is fixedly connected with the camera. According to the conveniently adjusted unmanned aerial vehicle camera support, the angle of the camera can be effectively adjusted without adjusting the position of an unmanned aerial vehicle, fine adjustment can be performed, the battery life of the unmanned aerial vehicle is prolonged, and the camera support is reasonable in design, simple in structure and suitable for production, popularization and application.

The invention relates to a drawer releasing device which can automatically release a drawer by simple braking on the position far away from the drawer. The drawer structure comprises a support frame and a locking device, wherein the support frame comprises a substrate and a sliding table; the sliding table and the substrate are in sliding fit and are installed on the substrate in an inclined mode; the locking device comprises a locking unit and a braking unit, wherein the locking unit comprises two locking arms which can be installed on the substrate in a rotatable mode; each locking arm is provided with a junction end and a driving end, wherein the driving end is connected with a brake cable; a magnetizer is arranged between two junction ends of the two locking arms and the sliding table correspondingly matched with the locking arms, so that the sliding table and the two junction ends of the two locking arms can mutually attract when the sliding table slides into the cavity of the drawer to lock the sliding table; and when a brake lock is driven to cause the two driving ends of the locking arms to oppositely move, two junction ends simultaneously rotate to cause the two junction ends to separate from the sliding table so as to realize that the sliding table can freely slide out of the cavity of the drawer. The locking unit is simple to assemble, assembling precision is lowered, and locking and releasing structure is reliable. The impact force of the substrate can be effectively eliminated, the substrate and a cabinet body are protected, and the service life of the substrate and the cabinet body can be prolonged.

The invention discloses a manufacturing method of a projector bracket with an adjusting function. The manufacturing method comprises the following steps of forming a first internal thread adjusting hole in an adjusting seat; forming a second internal thread adjusting hole in a first adjusting screw rod; determining that the first adjusting screw rod can be in screw-thread fit with the first internal thread adjusting hole for use; determining that a second adjusting screw rod can be in screw-thread fit with the second internal thread adjusting hole for use; determining that the thread pitch of the first adjusting screw rod is greater than that of the second adjusting screw rod; and mounting a roll ball at one end of the second adjusting screw rod. By means of the manufacturing method of the projector bracket with the adjusting function, the angle can be effectively adjusted, the service life is prolonged, the application range is wide, and the manufacturing method is simple.
