The invention belongs to the technical field of display screen processing, in particular to a manufacturing method of a special-shaped transparent display screen. During design of parallelogram, the parallelogram must be supplemented to be rectangular for machining; a supplementation direction is selected, poor connection caused by the fact that the same line is divided into different laser headsfor processing is avoided; the direction should be noticed when the parallelogram is completed; during pattern design, designing is carried out by taking an etching pattern as a reference; film cutting is carried out, under limitation by the working principle of a bonding machine (only the glass edge can be machined within the range of 3-5 mm, and the advancing direction is a straight line). The supplemented rectangle must be cut; the FPCB edge can be processed only after being manufactured into the glass edge, and in order to protect the pasted LED CHIP from being damaged, an anti-adhesive tape and a film are adopted to cover the part above the FPCB line, and then cutting, breaking and subsequent processing are carried out until binding is finished, and differentiated production of the parallelogram and a standard product is completely finished.

The invention relates to the technical field of manure leakage plate cleaning, and discloses an automatic cleaning brush device for manure leakage plate cleaning. The automatic cleaning brush device comprises a brush disc and a fixing plate, a circular through hole is formed in the middle of the top surface of the fixing plate, and an annular groove is formed in the inner side wall of the circular through hole. A plurality of balls are movably connected to the inner top wall and the inner bottom wall of the annular groove, a mounting plate is movably connected to the inner side of the circular through hole, L-shaped rods are fixed to the two sides of the brush disc, the bottom ends of the L-shaped rods are sleeved with sleeve rods, and the bottom ends of the sleeve rods are fixed to the top of the mounting plate. According to the automatic cleaning brush device, sleeves and multiple removing pieces are arranged, the sleeves can effectively gather brush sets composed of multiple bristles so that the removing pieces can conveniently remove impurities in the brush sets, and the removing pieces composed of long rods and cones in the shape of the parallelogram can effectively avoid the phenomenon that the bristles are bent when the brush sets move up and down.

The invention relates to the technical field of balance cars, and discloses a balance car with a deformable frame. The balance car comprises a first frame body, second frame bodies, handlebar assemblies, elastic parts and two wheels; the second frame bodies are correspondingly arranged below the first frame body at intervals; the handlebar assemblies are rotationally installed on the first frame body and the second frame body respectively. When the handlebar assemblies swing leftwards and rightwards, the first frame body can move leftwards and rightwards in parallel relative to the second frame bodies along with the handlebar assemblies. One ends of the elastic parts are connected with the first frame body, and the other ends of the elastic parts are connected with the second frame bodies;the two wheels are rotationally installed on the left side and the right side of the first frame body respectively and rotationally connected with the left sides and the right sides of the second frame bodies respectively.
