A detection method of a chemical detection instrument with a switch protection structure against false touch comprises the following steps:

A. before a user uses the instrument body 1, the user places a pre-recorded fingerprint on the fingerprint registration machine 71 for fingerprint identification registration in advance, after the fingerprint registration machine 71 authorizes the user with correct fingerprint identification registration, the fingerprint registration machine 71 sends a signal instruction to the controller 4, the controller 4 controls the electric push rod 73 to drive the push seat 74 to extend and retract backwards, the push seat 74 drives the first slide block 75 to slide in the first slide groove 72, so that the push seat 74 synchronously drives the three connecting rods 76 to adjust downwards, the three connecting rods 76 are gradually adjusted to be in an inclined state from an original vertical state, the three connecting rods 76 drive the support plate 78 to move downwards through the lifting seat 77, the support plate 78 drives the connecting seat 79 to move downwards, the connecting seat 79 drives the sliding sleeve 11 to slide downwards on the surface of the sliding column 12, and simultaneously drives the second slide block 14 to slide downwards in the second slide groove 13, therefore, the connecting seat 79 drives the shielding plate 710 to move downwards, the shielding plate 710 is gradually separated from the first limiting strip 16 and the second limiting strip 18, meanwhile, the shielding plate 710 drives the guide column 19 to slide downwards in the guide cylinder 20 until the shielding plate 710 completely leaves the surface of the operation switch key of the operation panel 6, a user can perform detection operation on chemical substances to be detected through the operation switch key, and the detection result of the chemical substances is displayed by the display 3 through the controller 4;

B. before the user detects the chemical substance, the user pulls the pull ring 810 outwards in advance, the pull ring 810 drives the slide rod 88 to slide outwards in the slide cylinder 87, the slide rod 88 drives the buffer spring 89 to compress, the slide rod 88 drives the clamping seat 811 to move outwards, then the user places the container containing the chemical substance to be detected in the placement groove 84 of the placement plate 83, then the user loosens the pull ring 810, the buffer spring 89 is restored to the reset state from the compression state, the buffer spring 89 drives the clamping seat 811 to clamp and fix the container containing the chemical substance to be detected, when the user needs to perform multi-angle observation and detection on the chemical substance, the user can rotationally cooperate in the bearing seat 81 through the rotating column 82, then the user can grip the handle 85 to drive the placement plate 83 to rotationally adjust, and then circumferentially slide-cooperate in the circular sliding groove 21 through the spherical slider 22, the placing disc 83 drives the container filled with the chemical substances to be detected to rotate, observe and detect, so that the visual detection operation of the chemical substances is realized;

C. after the chemical substance detection is completed, the user places the container in the positioning groove 101 in the placing seat 9 until the bottom of the container is clamped into the limiting groove 105, and meanwhile, in the downward placing process of the container, the container drives the limiting spring 103 to extrude into the groove 102 through the extrusion positioning head 104, and meanwhile, due to the fact that the force is mutual, the limiting spring 103 also elastically supports and positions the container through the positioning head 104.
