[0002] The controller, DC power converter and AC power converter in the charger all include a housing and components such as a circuit board disposed inside the housing. For ease of description, the housing and components such as the circuit board disposed inside the housing can be referred to as target objects. In order to achieve a fixed connection between the target objects, bolts or U-shaped strapping buckles 18 are generally used. The common steps for connecting the target objects using the U-shaped strapping buckle 18 are: first, place the U-shaped strapping buckle 18 on the target object, such as Figure 1 As shown, the U-shaped packing buckle 18 is then pressed so that the U-shaped packing buckle 18 is initially stuck on the target object, and then the target object with the U-shaped packing buckle 18 initially stuck is placed under the pressure rod of the special press, and then the pressure rod is operated to move downward to squeeze the U-shaped packing buckle 18 until the U-shaped packing buckle 18 is completely buckled on the target. However, the relative position of the U-shaped packing buckle 18 and the pressure rod during the squeezing process is mainly visual, so it is easy to have deviations, resulting in the U-shaped packing buckle 18 tilting or twisting when the pressure rod squeezes the U-shaped packing buckle 18, and the connection cannot be completed smoothly, and the U-shaped packing buckle 18 may also be damaged.

Figure 1As shown, the bottom of the pad 4 is fixedly connected with a reset spring 15. When the U-shaped packing buckle 18 and the target object are placed on the pad 4, the reset spring 15 is first squeezed due to its overall thickness. After the U-shaped packing buckle 18 and the target object are aligned with the lower end of the pressure rod 5, the reset spring 15 can push the pad 4 until the U-shaped packing buckle 18 contacts the lower end of the pressure rod 5. At this time, the driving assembly drives the pressure rod 5 to move downward, squeeze the U-shaped packing buckle 18, so that the U-shaped packing buckle 18, the target object, and the pad 4 all move downward to squeeze the reset spring 15. When the reset spring 15 is squeezed and shrinks to the shortest state, the pad 4 and the target object cannot continue to move. At this time, the pressure rod 5 continues to move downward, which can push the U-shaped packing buckle 18 to move until the U-shaped packing buckle 18 is completely buckled on the target object. Even if the U-shaped packing buckle 18 is converted from the state of preliminary connection to the state of complete connection, the U-shaped packing buckle 18 and the target object placed on the pad 4 can be quickly positioned to improve work efficiency.
