[0026] Furthermore, the second movable bar 206 passes through the first groove 203 through a round bolt connection. One end of the limiting post 204 is fixedly installed on one side of the surface of the quick inspection instrument body 1. Through the setting of the first groove 203, the first groove 203 limits the position when the second movable bar 206 moves, thereby converting rotation into displacement in the horizontal direction.

[0027] Further, the adjustment mechanism 3 includes a main handle 301, a first square groove 302, a rotating block 303, a sub-handle 304, a rubber strip 305, a limiting block 306, and a second square groove 307. A main handle 301 is fixedly installed on one side of the surface of the rapid detector body 1. A first square groove 302 is formed on one side of the surface of the main handle 301. A rotating block 303 is installed on one side of the surface of the main handle 301. A sub-handle 304 is installed inside the main handle 301. A rubber strip 305 is adhered to one side of the surface of the rotating block 303. A limiting block 306 is installed inside the rotating block 303. A second square groove 307 is formed on one side of the surface of the sub-handle 304. Through the settings of the main handle 301, the first square groove 302, the rotating block 303, the sub-handle 304, the rubber strip 305, the limiting block 306, and the second square groove 307, the main handle 301 is the fixed part, and the sub-handle 304 can move inside the main handle 301. The rubber strip 305 on the surface of the rotating block 303 is used to increase the friction force for convenient rotation operation. When the rotating block 303 is rotated, the limiting block 306 inside rotates accordingly. One end of the limiting block 306 penetrates inside the first square groove 302 and can be fitted inside the second square groove 307 on one side of the surface of the sub-handle 304. By rotating the rotating block 303, the limiting block 306 is fitted with the second square groove 307 at different positions, thereby fixing the position of the sub-handle 304 inside the main handle 301 and realizing the adjustment of the handle length.

[0028] Further, the sub-handle 304 is installed on one side of the surface of the rotating block 303, and three groups of second square grooves 307 are formed. Through the setting of the rotating block 303, by rotating the operation, the limiting block 306 inside is driven to rotate, thereby changing the fitting position of the limiting block 306 with the second square groove 307 on the sub-handle 304, and realizing the adjustment and fixation of the position of the sub-handle 304 inside the main handle 301.

[0029] Further, one end of the limiting block 306 penetrates inside the first square groove 302, and one end of the limiting block 306 is fitted inside the second square groove 307. Through the setting of the limiting block 306, by switching and fitting between different second square grooves 307, the adjustment of the handle length or shape is realized.

[0030] Working principle: First, the fixing plate 201 is fixed on the rapid detector body 1 to provide support for the entire mechanism. The limiting posts 204 limit the moving ranges of the first slider 207 and the second slider 208, enabling them to slide only within the sliding grooves 202. The first movable bar 205 and the second movable bar 206 are cross-mounted, the third movable bar 210 and the fourth movable bar 211 are cross-mounted, and the fifth movable bar 216 and the sixth movable bar 217 are cross-mounted. When the first movable bar 205 and the second movable bar 206 rotate around their connection points, they will push the first slider 207 to slide along the sliding groove 202. When the third movable bar 210 and the fourth movable bar 211 rotate around their connection points, they will push the second slider 208 to slide along the sliding groove 202. When the fifth movable bar 216 and the sixth movable bar 217 rotate around their connection points, they will push the third slider 209 to slide along the sliding groove 202. The sunshade 215 at one end of the third slider 209 changes its position along with the movement of the first slider 207, the second slider 208, and the third slider 209, thereby realizing the shading of the detection area or adjusting the shading range. Among them, the detector body 1 is equipped with a WIFI module and can connect to the network independently, has the ability of automatic discrimination, does not need to rely on the computing power and networking ability of the mobile phone, and at the same time has the HTTP networking protocol, can automatically connect to the network to update the near-infrared model and upload the detection data and sample photos, which existing devices do not have. The main handle 301 is the fixed part, and the sub-handle 304 can move inside the main handle 301. The rubber strip 305 on the surface of the rotating block 303 is used to increase the friction force for convenient rotation operation. When the rotating block 303 is rotated, the internal limiting block 306 rotates accordingly. One end of the limiting block 306 penetrates inside the first square groove 302 and can be fitted into the second square groove 307 on one side of the surface of the sub-handle 304. By rotating the rotating block 303, the limiting block 306 is fitted with the second square grooves 307 at different positions, thereby fixing the position of the sub-handle 304 inside the main handle 301 and realizing the adjustment of the handle length.
