[0013] Preferably, the method comprises the following steps:

[0014] Step 1: Turn on the power, and then place the car lock body in the installation slot opened by the rotating plate. At this time, the installation plate set on the car lock body passes through the through slot opened by the rotating plate, and the installation plate is inserted into the installation block. Then, the bolt is inserted into the installation block and passes through the installation plate. Then, the bolt is rotated to make the bolt and the installation block spirally connected, and then adjusted up and down to make the lock opening set on the car lock body correspond to the hook ring;

[0015] The second step is to push the cross bar, which pushes the card plate to move toward the car lock body on the outside of the slide plate and the slide column. At this time, the slide bar drives the limit column, the plug rod and the connecting plate to move.

At this time, the plug rod pushes the connecting plate to move on the outside of the limit column, and the first spring is compressed. At the same time, under the action of the cross bar, the card plate moves downward. When the arc position in front of the limit plate set in the card plate contacts the car lock body, the car body pushes the card plate to move. At this time, the card plate drives the slider to move on the outside of the guide rod through the connecting block. At the same time, the second spring is compressed. After the cross bar moves to the appropriate position, part of the limit plate is pushed into the card plate, and another part of the card plate is set on the side of the car lock body to limit the car lock body laterally until the cross bar moves to the appropriate position.

Under the action of the car lock body, the rotating plate rotates around one side of the fixed plate through the rotating block, and the car lock body is removed from the hook ring;

[0017] Step 4: The electric telescopic rod is extended by the controller, and the electric telescopic rod drives the mounting block and the mounting plate to move through the connecting column, so that the rotating plate and the rotating block rotate on one side of the fixed plate in the opposite direction of step 3. At this time, the baffle plate fixedly connected to the rotating plate enters the buffer groove opened by the buffer shell. At this time, the baffle plate pushes the buffer plate, and the buffer plate pushes the rubber ball. At this time, the rubber ball is deformed under the action of the first deformation groove and the second deformation groove. At the same time, the positioning block and the positioning plate can fix the buffer plate on the rubber ball, so that the buffer plate will not fall off when the rubber ball is deformed. After the car lock body is stuck on the outside of the hook ring, the car lock body can be locked;

[0018] Step 5: Repeat the above steps to lock and open the car lock body multiple times to test the opening and closing life of the car lock body.

At this time, the arc end of the limiting plate in part of the card plate contacts the automobile lock body, and the automobile lock body is pushed into the card plate through the arc end of the limiting plate. At this time, the card plate drives the slider to slide on the outside of the guide rod through the connecting block. At this time, the second spring is compressed by force, and the other part of the limiting plate is arranged on the side of the automobile lock body to prevent the automobile lock body from moving. After the cross bar moves to the appropriate position, the first spring pushes the hemispherical section of the plug rod through the connecting plate to be stuck in the groove opened by the slide plate to realize the positioning of the cross bar, so as to position automobile lock bodies of different specifications, which is convenient for testing the durability of automobile lock bodies of different specifications;

[0022] 3. In the present application, by setting the fixed block, electric telescopic rod, connecting column, mounting block, bolts and mounting plate, the mounting plate can be directly inserted into the mounting block, and then the mounting plate can be limited by the bolts.
