After being squeezed, the drive sleeve will slide along the slide groove, and the drive sleeve will then drive the positioning rod to approach the automobile planetary carrier. When the four positioning rods are in contact with the automobile planetary carrier, the automobile planetary carrier can be positioned. After the positioning of the automobile planetary carrier is completed, the positioning state can be locked by the locking device. The positioning device has a simple structure, and the user can quickly position the automobile planetary carrier, which is convenient for the user to operate and improves the practicability of the device.
