An outer shell 14 is fixedly installed on the outer side of the sampler main body 1. Heat dissipation holes 15 are opened on the side of the outer shell 14.
[0033] Specifically, four installation holes 2 are symmetrically arranged. The outer shell 14 is specifically made of electromagnetic shielding material. The advantage is that when installing, bolts are passed through the installation holes 2 to fix the sampler main body 1, and the outer shell 14 improves the electromagnetic shielding effect of the sampler main body 1.
[0034] Specifically, two sliding grooves 5 are symmetrically arranged inside the groove 3 respectively. The baffle 6 is in an "L" shape structure. The advantage is that the sliding groove 5 plays a guiding role for the baffle 6.
[0035] Specifically, a convex block 16 is fixedly installed at the upper end of the baffle 6. The limiting block 8 fits with the inner side of the limiting groove 7. The baffle 6 is specifically made of electromagnetic shielding material. The advantage is that the staff moves the baffle 6 through the convex block 16. When the baffle 6 moves, the limiting block 8 moves inside the limiting groove 7 to prevent the baffle 6 from falling out, and the baffle 6 improves the electromagnetic shielding effect at the wiring terminal 4.
[0036] Specifically, the baffle 6 fits with the outer side of the sampler main body 1. The adsorption block one 9 and the magnetic adsorption block one 10 are magnetically connected. The advantage is that when the baffle 6 moves to the innermost side, the adsorption block one 9 and the magnetic adsorption block one 10 come into contact with each other and are adsorbed by magnetic force to prevent the baffle 6 from moving.
[0037] Embodiment Two:
