At the same time, the bolt drives the turntable to cooperate with the rotating shaft to rotate in place on the surface of the placement plate. At the same time, the support plate is driven to move toward the placement plate in conjunction with the principle of the threaded groove. At the same time, the support plate drives the two sliding rods to cooperate with the first slot hole on the placement plate to move toward the center of the placement plate. The sliding rod pushes the clamping plate to approach and fit the surface of the planetary reducer body. By rotating the bolt forward, the sliding rod pushes the clamping plate to cooperate with the placement plate to fit the planetary reducer body. The planetary reducer body is fixed and clamped by the clamping plates at both ends. The bolt can be stopped to complete the installation and fixation of the planetary reducer body.
