Rotate at the same time, so that the four sleeves move inward at the same time. At this time, the limit plate can prevent the rotation of the sleeves, thereby driving the four splints to move and clamp the wheel hub. The operation is simple, the use is convenient, the use efficiency is increased and the work is greatly reduced. Labor intensity of personnel;

In the utility model, under the cooperation of the mounting plate and the screw rod, the mounting plate is installed at the designated position through the screw rod. At this time, the tops of the four mounting plates are respectively inserted into the corresponding screw rods, and the four screw rods are screwed together. To the corresponding installation frame and installation plate, the chuck can be fixed conveniently, and the installation and disassembly are more convenient, which makes the device easy to use, thereby increasing the practicability of the device.
