[0025] Specifically, the embedded rail 1 is used to be pre-buried in the installation position, and the support plate 2 slides inside the embedded rail 1 to support the detachable rail 3. The detachable rail 3 can be removed for easy cleaning. Mounting blocks 4 are fixed at both ends of the embedded rail 1 to connect the two embedded rails 1 together. A push rod 7 is arranged inside the mounting block 4 to drive the support frame 8 on the push rod 7 to move. A connecting rod 9 is arranged on the support frame 8 to be connected to the sliding frame 10 to drive the sliding frame 10 to move when the support frame 8 moves. The sliding frame 10 is used to drive the sliding rod 12 to move on the sliding rod 11. The sliding rod 12 is used to clamp the inside of the latch 5, thereby fixing the latch 5.
