Embodiment 1

[0067] refer to Figure 8 , U-shaped locking bar 2 ends are fixedly connected with positioning rod 21, U-shaped locking rod 2 cross-section is square, positioning rod 21 cross-section is circular, positioning rod 21 diameter is less than U-shaped locking rod 2 width. The fixing cavity 41 communicates with a positioning cavity 48 for the positioning rod 21 to snap in, and the positioning cavity 48 cannot allow the U-shaped locking rod 2 to snap in. After the U-shaped locking rod 2 is inserted, the magnet 22 is facing the Hall sensor 11 for locking.

Embodiment 2

[0069] refer to Figure 9 The cross section of the U-shaped lock bar 2 is square, and the U-shaped lock bar 2 includes a U-shaped part 23 and three locking parts 24 sequentially connected to the ends of the U-shaped part 23, and the adjacent locking parts 24 are connected by rotating shafts. The locking part 24 is rotationally connected to the U-shaped part 23 . Each locking portion 24 is provided with a locking groove 25 for engaging the locking pin 65 and embedded with a magnet 22 . The fixing cavity 41 is provided through, so that the U-shaped locking rod 2 can pass through the bottom of the fixing seat 4 .

[0070] According to the insertion depth of the U-shaped locking rod 2, turn one of the corresponding locking parts 24 until the magnet 22 faces inward, and turn the other locking parts 24 180 degrees until the magnet 22 faces outward, and then slowly insert the U-shaped locking rod 2 In the fixed cavity 41 , when the Hall sensor 11 senses the magnet 22 , the locking ...
