The limiting block 12 is slidably connected in the slide 21. The notch of the slide 21 is an open-shaped inclined surface. When the limiting block 12 contacts the inclined surface during the process of sliding the limiting block 12 into the limiting groove 22, the limiting block 12 slides into the limiting groove 22 along the inclined surface. The operator can slide the limiting block 12 into the limiting groove 22 more smoothly, preventing the insertion rod 11 from sliding in the slide 21, and the insertion rod 11 can be more conveniently inserted into the slide 21.

[0031] Reference Figure 2 and Figure 3, a clamping structure for clamping the plug rod 11 in the slide groove 21 is provided in the sand blocking rod 2, and the clamping structure includes a clamping bolt 6, a threaded hole 61 perpendicular to the axis of the sand blocking rod 2 is provided on the surface of the sand blocking rod 2, and the threaded hole 61 is connected with the two slide grooves 21, and an arc groove 62 is provided on the surface of the plug rod 11.

Then the sand guard bar 2 is rotated to make the block 3 slide along the transverse slot 242. When the block 3 slides in the transverse slot 242 away from the vertical slot 241, the block 3 contacts the inclined surface of the bayonet 4, thereby pressing the bayonet 4 into the pin slot 42 until the block 3 reaches the end of the transverse slot 242.
