Roller 17, the inner wall of the sliding plate 3 is provided with a spring 18, the sliding plate 3 is fixedly installed with a limit rod 10 on the side close to the base 1, the inner wall of the mounting shell 7 is fixedly installed with a fixed rod 12, the inner wall of the mounting shell 7 is slidingly connected with the quadrupole body 13 and the fixed ring 14, the outer wall of the fixed ring 14 is fixedly installed with an extension block 15, the inner wall of the extension block 15 is rotatably connected with a threaded column 20, and the inner wall of the extension block 15 is slidingly connected with a locking pin 21. In the above structure, there are two limit rods 10, and the two limit rods 10 are symmetrically arranged on the outer wall of the sliding plate 3 close to the base 1. The limit rods 10 extend to the inside of the base 1, so that the base 1 limits the sliding plate 3 through the limit rods 10.
[0023] In a preferred embodiment, the diameter of the sealing ring 8 is the same as the inner wall diameter of the mounting shell 7, and the centers of the mounting shell 7 and the sealing ring 8 are on the same axis. In the above structure, when the box body 2 and the fixed shell 4 are fitted together, the mounting shell 7 is located outside the sealing ring 8, and the contact surface between the mounting shell 7 and the outside of the base 1 is sealed by the sealing ring 8.
[0024] In a preferred embodiment, the cylindrical roller 17 is located above the fixed pin 19, and the middle part of the wire rope 16 is overlapped on the outer wall of the cylindrical roller 17. In the above structure, by pulling one end of the wire rope 16, the middle part of the wire rope 16 moves on the outer wall of the cylindrical roller 17. At this time, the other end of the wire rope 16 drives the fixed pin 19 to rise vertically.
[0025] In a preferred embodiment, the inner wall of the base 1 is provided with two circular grooves, and the diameter of the circular grooves is the same as the bottom diameter of the fixing pin 19. The square grooves on the inner wall of the base 1 are respectively located on both sides of the inner wall of the base 1. In the above structure, the two different circular grooves on the inner wall of the base 1 are clamped by the fixing pin 19, so that the fixing points of the sliding plate 3 are different. When the fixing pin 19 is clamped with the inner circular groove, the fixed shell 4 on the top of the sliding plate 3 is fitted with the box body 2. When the fixing pin 19 is clamped with the outer circular groove, the box body 2 is separated from the fixed shell 4.
[0026] In a preferred embodiment, a notch is provided on the outer wall of the fixing rod 12, and the diameter of the notch is the same as the diameter of the locking pin 21. In the above structure, the position of the locking pin 21 is fixed by inserting the locking pin 21 into the inner wall of the fixing rod 12, thereby fixing the fixing ring 14 and the extension block 15.
[0027] In a preferred embodiment, the threaded column 20 passes through the locking pin 21, and the interior of the threaded column 20 and the locking pin 21 are threadedly connected. In the above structure, by rotating the threaded column 20, the thread on the outside of the threaded column 20 rotates, and then the threaded column 20 drives the locking pin 21 to move through the rotation of the thread.
[0028] Working principle: the test sample is put into the feed pipe 6 so that the test sample reaches the inside of the box body 2 through the feed pipe 6. The test sample reaching the inside of the box body 2 reaches the inside of the detection device 5 through the mounting shell 7. The detection device 5 detects the fipronil content inside it. When the equipment needs to be repaired, the pulling frame provided on the outside of the sliding plate 3 is pulled, and the fingers are passed through the inside of the handle 11 to make a fist. At this time, the handle 11 is pulled, and the handle 11 drives the pull rod 9 to move, and the pull rod 9 drives one end of the fixed pin 19 to move, thereby causing the other end of the wire rope 16 to drive the fixed pin 19 to move upward, thereby causing the fixed pin 19 to disengage from the circular groove on the inner wall of the base 1. At this time, the fixed relationship of the sliding plate 3 disappears, and the sliding plate 3 can be pulled. When the sliding plate 3 moves, the fixed pin 19 will follow The sliding plate 3 moves, and when the fixing pin 19 moves to above another circular groove on the inner wall of the base 1, the spring 18 pops out the fixing pin 19, so that the fixing pin 19 is fixed, and thus the sliding plate 3 is fixed. While moving, the sliding plate 3 drives the fixing shell 4 to move, so that the box body 2 and the fixing shell 4 are separated, thereby dividing the equipment into two modules, which is convenient for internal maintenance. When the quadrupole body 13 needs to be repaired or replaced, the quadrupole body 13 needs to be taken out first. By rotating the threaded column 20, the threaded column 20 drives the locking pin 21 to move, so that the locking pin 21 is separated from the circular groove on the outer wall of the fixing rod 12, thereby eliminating the fixing relationship of the fixing ring 14. At this time, the fixing ring 14 is taken out, so that the fixation of the quadrupole body 13 disappears, and the quadrupole body 13 is taken out for maintenance or replacement.
