When the device is used, the stroke of the oil filling port of the charging port can not be larger than 3mm in the unlocking and locking processes of the switch. The hanging shell is pressed downwards, the second hanging column 613 is not moved, the process of moving upwards is relatively, the second hanging column 613 can enter a hanging point or be unlocked to leave the groove as long as the hanging column is cut to exceed the step edge by the upper inclined plane, the second limit step 6052 also plays a role of guiding the hanging column, the diameter and unlocking stroke range of the hanging column are wide, the diameter of the second hanging column 613 can be designed to be 1.5-2.5 mm, and the pressing stroke can be designed to be 1.5-3 mm.

Specifically, in this embodiment, the height of the second step 6035 is 0.5mm, the height of the third step 6036 is 0.5mm, and the height of the first step 6032 is 0.7mm (the height values of the first step 6035, the second step 6036, and the first step 6032 are not fixed, and a guiding function can be performed).

Since the initial guide groove 6034 has a 1mm drop from the third step 6036, the limit step behind the elastic sheet 611 needs to be free from the 1mm drop so as to avoid interference when the hanging column reaches the highest position. The locking point is located on the third step 6036, the third step 6036 has a fall of 0.7mm, the elastic piece 611 is in a backward deformation state in the locking state, and the second hanging column 613 is inclined by about 4 °.

When the guiding hanging shell 603 is pulled strongly, the elastic piece 611 is forced to deform backwards until it touches the second limit step 6052. After the high pulling force of more than 200N, the steel plate is easy to be pulled and deformed and cannot be recovered. And finally, the hung height value is less, the step is easily broken by the stress and the second limit step 6052 is easily broken by the stress, and the stress is less than 200N.

It can be understood that, in the embodiment, the unlocking stroke is smaller and is 1.5mm to 2.5mm, and the strong pulling force is larger and is less than 200N.
