[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0021] like Figures 1 to 5As shown, this utility model includes a detection mechanism 1, a sampling camera assembly 28, a device body 2, and a lifting mechanism.

The top of mounting plate 4 is connected to the bottom of detection mechanism 1. The top of fixed plate 3 is evenly connected to the bottom of four sets of mounting blocks. The tops of four sets of mounting blocks 8 are slidably fitted through buffer components and pressure block 9. First, the operator moves the detection mechanism and sampling camera component to a suitable position through the main body of the device. Then, the operator starts the power component, which makes the two sets of bidirectional screws rotate.

Two sets of second gears 12 are evenly arranged on the outer side of the rotating rod 14. One end of each set of second gears 12 meshes with one end of the first gear 11. When the operator starts the stepper motor, the stepper motor drives the second gears to select through the rotating rod. The meshing of the first and second gears causes the two sets of bidirectional screws to rotate, allowing the operator to quickly adjust the height of the detection mechanism, reducing the operator's workload and improving the convenience and practicality of the device.

The operator then starts the stepper motor, which drives the second gear to rotate via the rotating rod. The first and second gears mesh and engage, causing two sets of bidirectional screws to rotate. Four sets of first sliding holes slide the connecting plate via limit blocks and are hinged to the hinge seat and support rod, allowing the mounting plate to raise and lower the detection mechanism and sampling camera assembly until the desired height is reached.
