Example Embodiment

[0066] Example 1:

[0067] Refer Figure 8 The U-shaped lock rod 2 is fixed to the positioning rod 21, the U-shaped lock rod 2 is square, the positioning rod 21 is circular, and the positioning rod 21 is less than the U-shaped lock rod 2 width. The fixing chamber 41 communicates with the positioning chamber 48 supplied with the positioning rod 21, and the positioning chamber 48 cannot be attached to the U-shaped lock bar 2. After the U-shaped lock rod 2 is inserted, the magnet 22 is positively locking the Hall sensor 11.

Example Embodiment

[0068] Example 2:

[0069] Refer Figure 9 The U-shaped lock rod 2 is square, and the U-shaped lock rod 2 includes a U-shaped portion 23, and three sequentially connected to the locking portion 24, and the adjacent locking portion 24 is rotated between the adjacent locking portions 24. The locking portion 24 and the U-shaped portion 23 are rotated. Each locking portion 24 is provided with a locking groove 25 that is bocked by the locking pin 65 and is equipped with a magnet 22. The fixing chamber 41 runs through the setting such that the U-shaped lock rod 2 can be passed through the bottom of the fixture 4.

[0070] According to the U-shaped lock rod 2, the depth of which is inserted, rotates the corresponding locking portion 24 to the magnet 22 toward the inside, and rotates the remaining locking portion 24 to 180 degrees to the outside, and then slowly insert the U-shaped lock rod 2 The fixing chamber 41, when the Hall sensor 11 induces the magnet 22, the lock pin 65 is inserted ...
