[0038] Embodiment 2: Figure 5 , Figure 8 and Fig.10 As shown, when the latch 9 is pressed onto the inner bottom surface of the lower groove 14, by rotating the rotating part 27 and pulling the pressure plate 32, the pressure plate 32 drives the connecting strip 30 to move, and the connecting strip 30 compresses the spring three 31 until the pressure plate 32 is located above the top block 10, and then the pressure plate 32 is released, and the elastic force of the slide bar 29 drives the connecting strip 30 and the pressure plate 32 to press down, so that the pressure plate 32 presses the top block 10 and the latch 9, thereby further fixing the upper clamp 6 and the lower clamp 7, thereby improving the fixing effect.

[0039] During disassembly, the pressure plate 32 is disengaged from the top of the top block 10 by rotating the rotating part 27, and then the adjusting block 38 is rotated counterclockwise. The adjusting block 38 drives the rotating shaft 35 and the baffle 36 to rotate, so that the baffle 36 releases the limit on the tooth block 26, and the elastic force of the spring 25 drives the reset block 24 and the locking rod 19 to press down and reset, and the elastic force of the spring 1 22 drives the push block 16 to move and reset, so that the pin 9 and the upper clamp 6 can be pulled out, realizing convenient disassembly.

[0041] The top block 10 is pressed, and the top block 10 drives the latch 9 to be inserted into the top groove 33. The latch 9 continues to be inserted into the upper groove 13 and the lower groove 14 until the bottom end of the latch 9 abuts against the upper left inclined surface of the push block 16. The latch 9 squeezes the push block 16, causing the push block 16 to slide to one side of the locking rod 19. The push block 16 drives the pressure block 21 to move, and the pressure block 21 moves to compress the spring 22. When the push block 16 moves, it squeezes the bottom inclined surface of the locking rod 19, causing the locking rod 19 to rise.

[0042] The locking rod 19 drives the reset block 24 to rise, and the reset block 24 compresses the spring 25.

[0043] When the latch 9 is pressed onto the inner bottom surface of the lower groove 14, the rotating part 27 is rotated and the pressure plate 32 is pulled, so that the pressure plate 32 drives the connecting strip 30 to move, and the connecting strip 30 compresses the spring 31 until the pressure plate 32 is located above the top block 10. The pressure plate 32 is then released, and the elastic force of the slide bar 29 drives the connecting strip 30 and the pressure plate 32 to press down, so that the pressure plate 32 presses the top block 10 and the latch 9, thereby further fixing the upper clamp 6 and the lower clamp 7, thereby improving the fixing effect.

[0044] By rotating 27, the pressure plate 32 is disengaged from the top of the top block 10, and then the adjusting block 38 is rotated counterclockwise. The adjusting block 38 drives the rotating shaft 35 and the baffle 36 to rotate, so that the baffle 36 releases the limit on the tooth block 26, and the elastic force of the spring 25 drives the reset block 24 and the locking rod 19 to press down and reset, and the elastic force of the spring 1 22 drives the push block 16 to move and reset, so that the pin 9 and the upper clamp 6 can be pulled out, realizing convenient disassembly.
