The top front end of the supporting barrel 1 is fixedly connected to a positioning block 205, and the setting of the positioning block 205 can fix the two groups of connecting columns 208 when they are opened, and the top inner wall of the supporting barrel 1 is slidably connected to a positioning frame 201, which is provided with two groups, respectively located on the left and right sides of the movable column 203, and the inner walls of the two positioning frames 201 are provided with half-thread grooves, and the two groups can be assembled into a complete The left side of the sled is fixed with a socket 207, and the socket 207 is L-shaped. The right side of the sled is fixed with a socket 206, which plays a role in limiting the position of the sled. The right end of the sled is rotatably connected to the baffle 202, which is formed by two sets of hinged plates. When the sled moves, the baffle 202 is rotated. The inner wall of the support barrel 1 is slidably connected to the sampling tube 6, and the top of the sampling tube 6 is fixedly connected to the support column 5. The sampling tube 6 is used for sampling. This is the prior art and will not be explained in detail here. The top of the support column 5 is rotatably connected to the connecting plate 7. The setting of the connecting plate 7 can play a storage role. The top of the connecting plate 7 is rotatably connected to the threaded rod 3. The rotation of the threaded rod 3 can drive the sampling tube 6 to move vertically. The outer wall of the bottom end of the support barrel 1 is provided with a storage mechanism 4. The storage mechanism 4 can be folded to accommodate the whole, so as to achieve the effect of convenient transportation.

[0035] Reference Figure 2-Figure 4The outer arc surface of the movable column 203 is slidably connected to the inner wall of the top end of the supporting barrel 1, and the sliding of the two can drive the connecting column 208 to rotate. The bottom end of the rotating seat 204 is plugged into the inner wall of the positioning block 205, and the protrusion on the rotating seat 204 is plugged into the positioning block 205. At this time, the two sets of positioning frames 201 are in an open state, and the threaded rod 3 can be moved upward. The rear end of the connecting column 208 is rotatably connected to the front end of the positioning frame 201. The two rotate to avoid motion interference. The right end of the baffle 202 is rotatably connected to the inner wall of the top end of the supporting barrel 1. The rotation of the two makes it possible for the positioning frame 201 to move. At this time, the two hinged plates will rotate, and the inner wall of the connecting seat 206 is threadedly connected with a bolt 209. The bolt 209 plays a limiting role. The right end of the socket 207 is plugged into the inner wall of the connecting seat 206. The two are plugged together to achieve the effect of preliminary positioning. The bottom end of the bolt 209 is threadedly connected to the inner wall of the socket 207. The threaded connection can fix the two groups of positioning frames 201 after they are brought together. The outer wall of the threaded rod 3 is threadedly connected to the inner wall of the positioning frame 201. When the two groups of positioning frames 201 are fixed, the threaded rod 3 can be rotated to move the sampling tube 6 downward to perform the sampling operation.

[0036] Reference Figure 1 、 Figure 5 and Figure 6 The storage mechanism 4 includes a bottom plate 401, and the outer wall of the bottom plate 401 is rotatably connected to the outer wall of the bottom end of the support barrel 1. The two can be rotated to be in a horizontal state. At this time, the sampling operation can be carried out. The outer wall of the support barrel 1 is fixedly connected to the horizontal plate 402. The setting of the horizontal plate 402 makes the bottom plate 401 only able to rotate ninety degrees. The left end of the bottom plate 401 is fixedly connected to a connecting plate 404. The connecting plate 404 is set to a semi-ring setting near the side of the threaded rod 3, and the material is plastic. The front end of the bottom of the support barrel 1 is fixedly connected to a limit block 403, which plays a limiting role. The inner wall of the limit block 403 is elastically connected to a movable rod 406 through a connecting spring 407. The top of the movable rod 406 is fixedly connected to a plug-in column 405. The plug-in column 405 is U-shaped and consistent with the movement trajectory of the movable rod 406.

[0037] Reference Figure 5-Figure 6When the bottom plate 401 is rotated downward, due to the setting of the cross plate 402, the bottom plate 401 can only rotate ninety degrees. The outer arc surface of the threaded rod 3 is clamped with the inner side wall of the connecting plate 404. When the two sets of connecting plates 404 are in the retracted state, a plastic buckle is formed, which is then clamped with the outer arc surface of the threaded rod 3 to fix the threaded rod 3.

[0038] The working principle is as follows: when sampling is required, the movable column 203 is pushed to move inward, and the connecting column 208 connected to the rear end of the movable column 203 is rotated to open and rotate with the movement of the movable column 203, and then the rotating seat 204 is rotated so that the bottom end protrusion of the rotating seat 204 is plugged into the inner wall of the positioning block 205. At this time, the two sets of positioning frames 201 are in the open state, and then the threaded rod 3 can be moved upward to achieve the movement of the sampling tube 6 upward. The operation is simple and convenient. When the sampling operation is required, the rotating seat 204 is rotated to release the limit, and then the movable column 203 can be pulled outward to make the two sets of positioning frames 201 move toward the middle, thereby making the connecting seat 206 and the plug-in seat 207 plugged, and then the bolt 209 is screwed to fix the two sets of positioning frames 201. The half-thread grooves on the inner walls of the two sets of positioning frames 201 form a complete thread groove, and then the threaded rod 3 is screwed downward to make the sampling tube 6 move downward for sampling operation.

[0039] When storage is required, move the movable rod 406 downward, then rotate the bottom plate 401 to a horizontal state that fits the outer wall of the support barrel 1, and then loosen the movable rod 406. At this time, due to the elasticity of the connecting spring 407, the plug-in column 405 is plugged into the connecting plate 404 to complete the fixation. Then, the threaded rod 3 is rotated horizontally along the connecting plate 7, so that the outer arc surface of the threaded rod 3 and the plastic buckle composed of the connecting plate 404 are snapped together to complete the fixation, so as to facilitate the operation.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
