Specific embodiment
Below in conjunction with attached drawing, specific embodiment of the present utility model is described in further detail, so that the utility model skill
Art scheme is more readily understood and grasps.
With reference to Fig. 1, Fig. 2, a kind of gas chromatograph is present embodiments provided, including instrument body 1, the one of instrument body 1
Side is equipped with anti-theft device；Anti-theft device includes housing 21, and the middle part of housing 21 is vertically arranged with channel 211, channel 211 it is upper
The diameter of half part is less than its lower half portion, and recessed shoulder is formed between upper part and lower part；Motion bar 3 is installed in channel 211,
Motion bar 3, which is located on the side wall in the lower half portion of channel 211, has deck 31, and is arranged with spring 5；One end of spring 5 with
Deck 31 contradicts, and the table top of the other end and recessed shoulder contradicts；In its natural state, spring 5 by motion bar 3 towards the bottom of channel 211
Portion pushes, and is pushed out to outside housing 21.
The side of channel 211 has installation cavity, and inductor 61 is equipped on the installation cavity side wall adjacent with channel 211, blocks
There is the trigger unit 62 that can trigger the inductor 61 on seat 31；In the present embodiment, which uses tongue tube, trigger unit
Part 62 uses magnet.When the bottom end of motion bar 3 and desktop contradict, the trigger unit 62 is close to inductor 61.
