[0030] In this embodiment, the locking mechanism includes a base 1, a spring 2, a pin 3 and a main body 4. When in use, the main body 4 is inserted into the insertion hole 14 inside the base 1. At this time, after the main body 4 enters the base 1, it first contacts the pin 3, and then squeezes the pin 3 to slide in the sliding groove 9. During this process, the pin 3 squeezes the spring 2 and the through rod 12 on the pin 3 slides in the through hole 10 inside the base 1, while the pin 3 and the short rod 11 on the pin 3 slide in the sliding groove 9. When the main body 4 completely enters the base 1, the pin 3 is no longer blocked, and the compressed spring 2 exerts force to make the pin 3 directly enter the first hole 13 in the main body 4, completing the locking between the main body 4 and the base 1.
