One end of the locking lever 9 is provided with a baffle 91 for abutting against the outer wall of one side of the sliding lever 3, and the other end is provided with a pair of elastic hooks 92 for hooking the outer wall of the other side of the sliding lever 3.

As shown in fig. 3 and 4, a mutually communicated limit hole 93 penetrates between the shutter 91 and the lock lever 9, and a limit rod 94 is slidably connected to the limit hole 93. One end of the limiting rod 94 is provided with a pull ring 95, the other end is hinged with a plurality of pull rods 96, and the pull rods 96 are respectively hinged on the inner side walls of the elastic clamping hooks 92.

When the sampling tube 5 is installed, the installation rod 6 above the sampling tube 5 is inserted into the installation hole 7 below the sliding rod 3, then the elastic hook 92 is embedded into the locking hole 8, and then the baffle 91 is driven to drive the locking rod 9 and the elastic hook 92 to slide along the inner wall of the locking hole 8. Until the baffle 91 is abutted against the outer wall of one side of the sliding rod 3, the elastic hook 92 is sprung open and hooks the outer wall of the other side of the sliding rod 3 tightly, thereby realizing the fixation of the sampling tube 5.

When the sampling tube 5 is disassembled, the pull ring 95 is pulled to drive the limiting rod 94 to move outwards, at the moment, the limiting rod 94 slides outwards along the inner wall of the limiting hole 93, and the pull rods 96 are pulled to move synchronously. Meanwhile, the pull rods 96 pull the elastic hooks 92 to approach each other, and pull the baffle 91 to drive the locking lever 9 and the elastic hooks 92 to slide outwards after the elastic hooks 92 are embedded into the locking holes 8. After the locking rod 9 and the elastic hook 92 are completely separated from the locking hole 8, the sampling tube 5 is pulled to move downwards, so that the sampling tube 5 is detached.

As shown in fig. 5, the sampling tube 5 includes a top plate 51 and a pair of wall plates 52 provided on the lower end surface of the top plate 51, the wall plates 52 are provided in a semicircular shape in cross section, and the pair of wall plates 52 are engaged with each other to form a circular shape.
