The invention discloses an aluminum support twisting device. The device comprises a base, wherein a left vertical plate is fixedly welded to the top of the base in the direction close to the left side, a right vertical plate is fixedly welded to the top of the base in the direction close to the right side, and a sliding rail groove is formed in the top of the base and located between the left vertical plate and the right vertical plate. The aluminum support twisting device is advantaged in that aluminum bracket plates are arranged in a twisting groove and a placing groove, after the position is adjusted, fixing bolts are screwed in threaded holes, movement of the aluminum bracket plates is limited by the fastening force of fixing bolts and fastening springs on the aluminum bracket plates,once twisted, the fixing bolts are screwed off, the fastening springs are pressed down, finished products are disassembled, and the convenient mounting and dismounting effect is achieved, when the aluminum bracket plates of different specifications need to be twisted, a movable base is moved to the designated position, a hand wheel is made to rotate to drive a clamping groove to clamp the aluminumsupport plates, a twisting motor is started to twist the aluminum support plates, and thereby the effect that the twisting device is adjustable is achieved.

The invention discloses an adjustable fixing device used for maintenance of motor shells and capable of achieving centering, and relates to the technical field of civil cleaning equipment. The fixing device comprises a mounting seat, the middle part of the mounting seat is rotatably connected with a rotary table, the middle part of the rotary table is provided with uniformly distributed limiting grooves, the middle parts of the limiting grooves are movably connected with limiting columns, and the back surfaces of the limiting columns are fixedly connected with movable blocks. According to the adjustable fixing device used for maintenance of the motor shells and capable of achieving centering, through cooperative use of the rotary table and the limiting columns, in an initial state, telescopic blocks are in a stretching-out state under the action of first springs, the movable blocks are located at the innermost side of the mounting seat, and when the shells are fixed, the shells are placed in the middle of the mounting seat firstly, then the rotary table is rotated, the movable blocks move towards the inner side of the mounting seat through the limiting grooves and the limiting columns, adjustment is performed according to the shells of different sizes, and the shells are clamped and fixed by clamping plates, so that the adjustable effect is achieved, the clamping range is increased, the cleaning cost is saved, and the cleaning efficiency is improved.
