DETAILED DESCRIPTION

[0025] The invention will be further described below with reference to the accompanying drawings and in combination with specific implementations, so that those skilled in the art can implement the invention with reference to the description. The protection scope of the invention is not limited to the specific implementations.

A locking mechanism is arranged between the second latch section 8 and the third latch section 9, and the locking mechanism includes two symmetrical Y-shaped buckles 11 which are elastically connected to the second latch section 8 respectively, and the Y-shaped buckle 11 includes a root 12 elastically connected to the second latch section 8 and a V-shaped foot. The third latch section 9 includes a side wall 13, and the V-shaped foot of the Y-shaped buckle 11 includes a first foot 14, and the first foot 14 protrudes from the side wall 13 in a direction away from the root 12. The latch hole 6 includes a slide groove 15 for the latch 5 to slide into, and the slide groove 15 includes a limiting groove 16 for limiting the movement of the latch 5, and the limiting groove 16 includes a limiting surface 17. The first foot 14 on the latch 5 includes a card point 18 that can resist on the limiting surface 17, and the latch seat 4 includes a limiting connection block 19 for limiting the movement of the latch 5 toward the spring piece 3. The latch 5 slides into the latch hole 6 along the slide grooves 15 on both sides of the latch hole 6. In this process, since the first clamping foot 14 on the Y-shaped buckle 11 protrudes relative to the side wall 13 of the third latch section 9, and the Y-shaped buckle 11 and the second latch section 8 are elastically connected, when the latch 5 slides in the latch hole 6, the Y-shaped buckle 11 will be squeezed by the groove wall of the slide groove 15, but this squeezing action does not affect the smooth sliding of the latch 5; when the latch 5 moves to the position where the first clamping foot 14 reaches the limiting groove 16, the squeezed Y-shaped buckle 11 will be released, and the first clamping foot 14 will recover in the direction of the limiting groove 16, so that the clamping point 18 on the first clamping foot 14 is just stuck on the limiting surface 17 of the limiting groove 16, thereby limiting the movement of the latch 5 in the direction away from the spring piece 3, that is, returning to the original path to disengage from the latch seat 4. At the same time, the limiting connection block 19 on the latch seat 4 limits the latch 5 from continuing to move in the direction of the spring piece 3.
