The invention discloses special teaching auxiliary equipment for business administration, and relates to the technical field of teaching equipment. The special teaching auxiliary equipment comprises abox body. The bottom surface of the box body is fixedly connected with a base; and universal wheels are fixedly mounted at four corners of the bottom surface of the base. According to the special teaching auxiliary equipment for business administration, through cooperation of a driving motor, a bidirectional screw rod, a second threaded sliding block, a lifting plate, a sliding groove and a second connecting plate, lifting of the lifting plate can be effectively controlled, the lifting plate can be more stable during lifting, and the lifting plate is prevented from deviating during lifting, so that the effect of adjusting the height of a main teaching board is effectively realized; and through cooperative arrangement of a fixing frame, a rotating base, a limiting hole, a limiting rod, a fixing column, a universal ball, a sliding groove plate, a second fixing frame and a telescopic spring, adjustment of the left-right angle of the main teaching board can be effectively controlled, therotating base with the adjusted angle can be limited, and therefore, the stability of the main teaching board is guaranteed.

The invention discloses a display screen supporting frame with the adjustable height and angle. The display screen supporting frame comprises a display screen, a first supporting platform and a bottombox body. When the display screen supporting frame works, a second rack can be pushed to move horizontally under the action of an electric cylinder, and because the second rack is engaged with a second gear, the second gear is driven to rotate, and thus a first gear rotates; because the first gear is engaged with a first rack, the first rack slides in the vertical direction, and thus the first supporting platform is driven to lift, and the lifting function of the display screen is achieved; a sliding block slides, so that a connecting rod pushes the display screen to rotate around the centerof a second connecting part, the angle adjustment function of the display screen is achieved, and the angle of the display screen can be fixed simply by tightening a locking bolt after adjustment is completed; and the operation is simple and convenient, the display screen can be simply adjusted to a reasonable position according to the height and the working state of a user, the user can feel comfortable during work, and the working efficiency is improved.

The invention discloses shot blasting cleaning equipment for manufacturing a water pump shell and a using method of the shot blasting cleaning equipment, and belongs to the technical field of shot blasting cleaning equipment. A shot blasting cleaning device for manufacturing a water pump shell comprises an upper tank body and a lower tank body which are communicated with each other and provided with a cabin door, and further comprises a shot blasting mechanism arranged in a cavity of the upper tank body, the shot blasting mechanism comprises a driving motor mounted at the top of the upper tank body, a driving shaft which is mounted at the output end of the driving motor, extends towards the inner cavity of the upper tank body and has a rectangular cross section, shot blasting parts which are connected to the outer wall of the driving shaft in a sliding manner and are distributed at equal intervals, and adjusting rods which are connected between the adjacent shot blasting parts and are automatically stretched and reset; the shot supply part is communicated with the shot blasting part; the clamping mechanism is arranged in the cavity of the upper tank body and annularly distributed on the periphery of the shot blasting mechanism; the rotary adjusting mechanism is mounted on the clamping mechanism and used for adjusting the clamping angle; dispersion adjustment of the shot blasting mechanism can be carried out according to the size of a workpiece, and the applicability is improved.
