Then a handle seat 9 is arranged, and a handle 10 is connected with a fixed rod 8 on a slide block 15. The handle 10 is pressed to drive the sliding block 15 and the pressing block 18 to move backwards together through the fixed rod 8.

3. Finally, the pressing handle 13 on the outer tube 6 is pressed and pulled, so that the connecting rod 14 drives the moving block 19 to move backwards at the same time, the inclined groove 191 on the moving block 19 enables the positioning pin shaft 17 to move outwards against the force of the third spring 20, the pressing block 18 loses the acting force of the positioning pin shaft 17 and swings reversely under the action of the second spring 16, the protrusion 181 of the pressing block is far away from the groove 111, at the moment, the brace 11 on the pull rod device 4 in the inner tube assembly penetrates through the rectangular hole of the slider 15 in the outer tube assembly, and the inner tube assembly can be installed in the outer tube assembly. After the inner pipe is assembled in place, the pressing handle 13 is released, the pressing handle 13 is reset under the action of the first spring 12, the moving block 19 is pushed to move forwards, the inclined groove on the moving block 19 enables the pin shaft 17 to move downwards under the elastic force of the third spring 20, the protrusion 181 of the pressing block 18 is pushed by the positioning pin shaft 17 and then pressed on the groove 111 of the brace 11, and meanwhile, the pin shaft 17 buckles the inner pipe and the outer pipe together to complete the assembly.

The telescopic adjustment of the inner pipe and the outer pipe is as follows:

when the pressing handle 13 in the fixed seat body 71 on the outer tube 6 moves backwards against the elastic force of the first spring 12 and the movable block 19 in the sliding pin seat body 51 is driven by the connecting rod 14 to move leftwards together, the inclined slot on the movable block 19 drives the positioning pin 17 to move outwards against the elastic force of the third spring 19 and the end part moves to the outside of the inner tube 3, meanwhile, the pressing block 18 on the sliding block 15 is bounced up by the second spring 16, the protrusion 181 of the pressing block 18 is separated from the groove 111 of the brace 11 of the pull rod device 4, at this time, the opposite positions of the inner tube and the outer tube can be moved and the pressing handle 13 is released, when the positioning pin 17 moves to the next through hole 31, the pressing handle 13 in the fixed seat body 71 moves forwards against the elastic force of the first spring 12, the inclined slot on the movable block 19 drives the positioning pin 17 to transmit into the through hole 31 on the inner tube 3, so that the protrusion 181 of the pressing block 18 moves downwards against the elastic force of the third spring 19 along with the positioning pin 17 to buckle the groove 111 of the brace 11, while pinning the inner tube 3.

The utility model adopts springs to position and reset at multiple positions, so that the telescopic mechanism can freely move in and out and is reliably positioned. Meanwhile, after the pull rod device hidden in the inner tube stretches in place along with the inner tube, the sampling clamp can be operated to open and close by moving the sliding block assembly to drive the pull rod device to move backwards through the movement of the pressing handle, and articles are convenient to collect.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. It will be understood by those skilled in the art that any modification, equivalent replacement, or improvement made on the technical solutions or parts of the technical features described in the above embodiments can be included in the scope of protection of the present invention within the spirit and principle of the present invention.
