This invention provides a special disassembly tool and method for abrasive rollers in automotive clutch steel sheet grinding equipment. The tool includes: a first fixing component mounted on the rotating shaft of the abrasive roller; a first disassembly component mounted on a first fixing nut on the rotating shaft of the abrasive roller; a second fixing component mounted on the back plate of the grinding equipment; and a second disassembly component fitted onto a second fixing nut on the rotating shaft of the abrasive roller. Both the first and second fixing components have contour holes that mate with the rotating shaft of the abrasive roller. The first fixing component manually restricts the rotation of the rotating shaft, and the second fixing component restricts the rotation of the rotating shaft by being fixed to the back plate and engaging with the contour holes. Both the first and second disassembly components have disassembly teeth, allowing the first and second fixing nuts to be disassembled by rotating the disassembly teeth. This invention solves the problems of inability to circumferentially lock the rotating shaft of the abrasive roller during disassembly and installation, and the inability of commonly used tools to achieve effective rotation in confined spaces.

The utility model relates to the technical field of windscreen wipers, and discloses a windscreen wiper for an automobile, which comprises a windscreen wiper arm and a brush strip, a mounting box is fixedly arranged at the front end of the windscreen wiper arm, the brush strip is arranged below the mounting box, adjusting components are arranged inside and outside the mounting box, a clamping seat is clamped at the middle end of the surface of the upper end of the brush strip, and the lower end of the adjusting component is connected with the clamping seat. According to the windscreen wiper for the automobile, by arranging the adjusting assembly, when the brush strip cannot be effectively attached to the front windshield of the automobile due to abrasion, an adjusting screw rod can be effectively driven to rotate synchronously by rotating a rotary knob, and under the limiting effect of a sliding block and a limiting sliding rod, an upper plate moves downwards in the vertical direction and pushes a lower plate to move downwards synchronously through a buffer spring; the lower plate pushes the brush strip to be tightly attached to the automobile front windshield through the connecting column, the brush strip does not need to be replaced, and the service life of the brush strip is prolonged.

The utility model relates to a partial composite beam-superposed composite column three-dimensional assembly type connecting joint which comprises a superposed composite column, a main beam and a secondary beam. The overlapped combination column comprises a steel pipe, and reserved pipes are arranged on the two faces, corresponding to the main beam, of the steel pipe. Each of the main beam and the secondary beam comprises an internal stress assembly and an external stress assembly, the internal stress assembly comprises H-shaped steel, and the external stress assembly is arranged between an upper flange and a lower flange of the H-shaped steel; the end, facing the laminated combination column, of a web of the H-shaped steel of the secondary beam protrudes and is provided with an open hole. The utility model has the beneficial effects that the prefabricated superposed combination column and the partial combination beam with the steel joint are adopted and can be quickly mounted after being transported to a site, the connection between beam and column members is convenient, quick, firm and reliable, the workload of on-site molding, mounting and welding is reduced, and only later concrete spraying construction is required after mounting and connecting, so that the construction efficiency is greatly improved. On the premise of ensuring the quality, the on-site construction procedure is simplified, and the construction time is saved.

The utility model discloses a regenerated paper pulp fiber separating device which comprises a separating box, a screen drum mechanism with an internal hollow structure is fixedly connected inside the separating box, the screen drum mechanism is used for separating paper pulp fibers, and screen hole assemblies are arranged inside the screen drum mechanism in an annular array mode.
