[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Please refer to Figure 1 - Figure 5 The bottom of the support frame 2 is provided with a fixing seat 3, and the fixing seat 3 is connected with the fixing seat 3 by a clamping assembly, so as to facilitate the quick disassembly and installation between the fixing seat 3 and the fixing seat 3. The fixing rods 5 are fixedly provided at the four corners of the fixing seat 3. When sampling is required, the fixing seat 3 is placed at the sampling position, and then the fixing seat 3 is pressed to make the fixing rod 5 inserted into the ground, so that multiple fixing rods 5 can be fixed at one time, thereby avoiding the problem that personnel need to install pins or bolts one by one, and improving the efficiency of installation. The top of the fixing rod 5 is provided with a rotating groove 10, and an inner rod 7 is slidably provided in the rotating groove 10. The bottom end of the inner rod 7 is conically set, and the bottom ends of the inner rod 7 are slidably matched with limiting rods 6 on both sides. The inner rod 7 is placed on the side wall of the fixing rod 5. After the fixing rod 5 is inserted into the ground, the inner rod 7 is pressed downward, and the inner rod 7 moves through the conical structure to make the limiting rod 6 move toward the periphery of the fixing rod 5. Then, the limiting rod 6 is inserted into the soil outside the fixing rod 5, so that the fixing rod 5 is limited, thereby completing the fixation of the fixing seat 3. Then, the support frame 2 is installed on the fixing seat 3 through the clamping assembly. The operation is convenient. An arc groove 9 is provided in the rotating groove 10, and an arc plate 11 that slidably cooperates with the rotating groove 10 is provided on the side wall of the inner rod 7. The arc plate 11 can slide through the side wall of the inner rod 7. After the position of the fixing rod 5 is limited, the inner rod 7 can be limited by the cooperation of the arc plate 11 and the arc groove 9, so as to avoid the displacement of the inner rod 7 during the sampling process of the sampling tube 1, so that the limiting rod 6 shrinks in the fixing rod 5, thereby causing the sampling tube 1 to be unable to stably perform sampling work.

[0022] See also Figure 2 , Figure 4 Preferably, one end of the fixed rod 5 close to the rotating groove 10 slides into the rotating groove 10, and the side wall of the fixed rod 5 is symmetrically provided with a guide groove 13 along the center. The limiting rod 6 is installed on the fixed rod 5 through the guide groove 13, and a tension spring 12 is provided between the limiting rod 6 and the guide groove 13. When the inner rod 7 moves downward, the limiting rod 6 moves toward the periphery of the fixed rod 5 through the conical structure, and when the inner rod 7 moves upward, the limiting rod 6 moves and contracts within the side wall of the fixed rod 5 under the action of the tension spring 12.

[0023] Further, preferably, a circular groove is provided at the top end of the inner rod 7, a rotating shaft 4 is rotatably connected in the circular groove, and a knob is provided at the top end of the rotating shaft 4, which facilitates rotation by personnel.

[0024] Furthermore, preferably, a square frame can be fixedly provided on the top of the four groups of inner rods 7, so that multiple groups of inner rods 7 can be moved synchronously, thereby improving the efficiency of installation and disassembly of the inner rods 7. At the same time, belts or chains can be provided between the multiple groups of rotating shafts 4, so that when one group of rotating shafts 4 is rotated, multiple groups of rotating shafts 4 can rotate synchronously.

[0025] See also Figure 2 , Figure 3 , Figure 5 Preferably, multiple groups of arc grooves 9 are arranged in an array along the side wall of the rotating groove 10, and multiple groups of arc plates 11 are arranged in an array on the side wall of the inner rod 7, and the number of groups of arc grooves 9 is twice the number of groups of arc plates 11, so that after the inner rod 7 moves on the fixed rod 5, the relative limit between the two can be better completed by the cooperation of the arc plates 11 and the arc grooves 9. The arc plate 11 is arranged below the rotating shaft 4, and the end of the arc plate 11 away from the arc groove 9 slides into the circular groove, and both ends of the arc plate 11 are semicircular structures, so as to facilitate the cooperation with the arc groove 9, and also avoid the arc plate 11 from happening To solve the problem of getting stuck, springs are provided on the side walls of the arc plate 11 and the inner rod 7, so that when the arc plate 11 is not subjected to external force, it can automatically shrink inside the side walls of the inner rod 7, thereby not affecting the movement of the inner rod 7 on the fixed rod 5. A trigger rod 8 is fixedly provided at the bottom of the rotating shaft 4. The trigger rod 8 is specifically a cam structure. The outer edge of the trigger rod 8 slides with the end of the arc plate 11 away from the arc groove 9. When the trigger rod 8 rotates, it can contact the arc plate 11 and push the arc plate 11 to move toward the arc groove 9. It should be noted that the rotating shaft 4 and the inner rod 7 are preferably connected by a threaded structure.

[0026] When in use, in the initial state, the limiting rod 6 is retracted into the side wall of the fixing rod 5, and the arc plate 11 is retracted into the side wall of the inner rod 7. When sampling is required, the fixing seat 3 is placed in a predetermined position, and then the fixing seat 3 is pressed down so that multiple groups of fixing rods 5 are inserted into the ground at the same time, and then the inner rod 7 can be pressed down so that the end of the inner rod 7 slides with the limiting rod 6, and then the limiting rod 6 is pushed to move toward the periphery of the fixing rod 5 and inserted into the soil, thereby completing the limitation of the relative position between the fixing rod 5 and the ground, so as to locate the position of the fixing seat 3, and then the rotating shaft 4 is rotated, and the rotation of the rotating shaft 4 drives the trigger rod 8 to rotate, and the trigger rod 8 rotates and cooperates with the arc plate 11, thereby pushing the arc plate 11 to move toward the periphery of the inner rod 7 and extend into the arc groove 9, thereby realizing the inner rod The relative limitation between 7 and the fixed rod 5 prevents the inner rod 7 from moving during the subsequent sampling process, causing the limiting rod 6 to shrink inside the fixed rod 5, causing the fixed rod 5 to lose its limitation, thereby affecting the sampling work. After the fixing seat 3 is fixed, the support frame 2 can be installed on the fixed seat 3 to carry out the sampling work. When the sampling work is completed, the rotating shaft 4 can be rotated to reset, so that the trigger rod 8 is separated from the arc plate 11, and the arc plate 11 is contracted into the inner rod 7 under the action of the spring, and then the inner rod 7 is pulled upward to separate the inner rod 7 from the limiting rod 6, allowing the limiting rod 6 to move and shrink in the side wall of the fixed rod 5 under the action of the tension spring 12, and then the fixed seat 3 is pulled upward to complete the disassembly of the sampling device. The operation is simple and fast, and the efficiency is improved.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
