As shown in fig. 1, the side surface of the protection cover 3 is provided with an opening, the protection cover 3 is provided with a limiting component for limiting the relative position of the host 1 relative to the protection cover 3, the limiting component comprises a stop block 31 which is rotatably connected to the side wall of the opening surface of the protection cover 3 and is used for abutting against the surface of the host 1, and the stop block 31 is provided with a plurality of stop blocks. When the host 1 is installed, the host 1 is placed in the protective cover 3, and the operation interface on the host 1 is arranged towards the opening. The stopper 31 is rotated to block the side of the main body 1 so that it does not slip out of the protection cover 3. The protective cover 3 is externally provided with a sunshade layer 32. The sunshade layer 32 includes an aluminum foil layer 321 and a polyester film layer 322. Can reflect solar radiation, obviously reduce the temperature of air and plants, and has more obvious effect on humidity regulation.

As shown in fig. 2, a sliding protrusion 41 is fixed on the sidewall of the sleeve 4, a sliding groove is formed on the mounting seat 5, and the sliding protrusion 41 is embedded in the sliding groove and is slidably connected to the sliding groove along the vertical direction. In this way, the sleeve 4 can only be moved in the vertical direction. The driving assembly 7 comprises a driven bevel gear 71 coaxially fixed at one end of the screw 6 far away from the sleeve 4, a driving bevel gear 72 meshed with the driven bevel gear 71, and a driving piece 73 installed on the mounting seat 5 and used for driving the driving bevel gear 72 to rotate, wherein the driving bevel gear 72 is axially fixed and is circumferentially and rotatably connected to the mounting seat 5. The driving member 73 is a hand-operated wheel coaxially fixed to the drive bevel gear 72.

The driving member 73 drives the driving bevel gear 72 to rotate, and the driving bevel gear 72 drives the driven bevel gear 71 to rotate, so that the screw 6 fixed to the driven bevel gear 71 rotates. The sleeve 4 sleeved and screwed on the screw 6 moves along the vertical direction. The protective cover 3 fixed to the sleeve 4 moves in the vertical direction. In this way, when the tripod 8 is spread apart and the height is not as desired, the height of the protective cover 3 is raised by the drive assembly 7.

As shown in fig. 1, tripod 8 includes three legs 81 hinged to mounting base 5, a fixing block 82 fixed to an end of each leg 81 remote from mounting base 5, an insertion rod 83 penetrating through fixing block 82 in a vertical direction and extending into the ground, and a spiral piece 84 fixed to a side wall of insertion rod 83. The number of the fixing blocks 82, the insertion rods 83, and the screw pieces 84 is the same as the number of the legs 81. The insertion rod 83 is pointed at one end. Still be fixed with stand 85 on the mount pad 5, coaxial cover is equipped with along stand 85 axial sliding connection in stand 85's installation cover 86 on the stand 85, and installation cover 86 circumference equipartition articulates there is three connecting rod 87, and the one end that installation cover 86 was kept away from to every connecting rod 87 is articulated with every stabilizer blade 81 one-to-one.

When the support is needed, the supporting feet 81 are moved outwards along the radial direction, the mounting sleeve 86 slides on the upright post 85, when the connecting rod 87 moves to be parallel to the horizontal plane, the opening angle of the three supporting feet 81 is the largest, and the total station is adjusted to start measurement. When the measurement is finished, the mounting sleeve 86 is slid downwards, the opening angles of the three supporting legs 81 are reduced along with the downward movement of the moving block until the three supporting legs 81 are folded to the minimum angle. The three legs 81 are connected together by the connecting rod 87, so the structure formed by the three legs 81 is more stable. After the tripod 8 is forked to a proper angle, the insertion rod 83 is inserted through the fixing block 82 and into the ground. Due to the spiral pieces 84 fixed to the side walls of the insertion rod 83, the insertion rod 83 can be firmly fixed to the ground by increasing the force bearing area between the insertion rod 83 and the soil and further increasing the friction force between the insertion rod 83 and the soil. So, when meetting the strong wind day, on tripod 8 firmly was fixed in the bottom surface under the effect of inserted bar 83, was difficult for being blown, guarantees the practical safety of sample thief.
