The connecting screw rod 8 passes through the through hole 19 and extends into the interior of the threaded sleeve 11. At the top of the outer part of the connecting screw rod 8, a positioning piece 13 is fixedly connected;

[0026] The positioning piece 13 is movably connected to the first side plate 7, and the connecting screw rod 8 is threadedly connected to the threaded sleeve 11;

[0027] The center line of the first set of plates 6 and the center line of the second set of plates 9 are on the same vertical plane, and the support plate 5 is fixedly connected to the installation cylinder 1;

[0028] Specifically, as Figure 1 、 Figure 3 and Figure 4 shown, during installation, the second set of plates 9 are attached to one end of the pipeline, and then the first set of plates 6 on both sides of the installation cylinder 1 are attached to the other end of the pipeline. Then, the connecting screw rod 8 is passed through the interior of the through hole 19 and then turned into the interior of the threaded sleeve 11. The rotating handle 15 drives the connecting screw rod 8 to rotate through the turntable14. After the connecting screw rod 8 is tightened, the first set of plates 6 and the second set of plates 9 can be positioned. The pipeline is clamped by the first set of plates 6 and the second set of plates 9 to realize the positioning of the microscope, achieving the rapid installation and fixation of the device.

[0029] Embodiment 2: At the bottom of the first set of plates 6 and the top of the second set of plates 9, inclined surface grooves 21 are opened. On both sides inside the inclined surface grooves 21, anti-slip rubber pads 20 are fixedly connected. At the bottom of one side of the second set of plates 9, a connecting plate 10 is fixedly connected;

[0030] The center line of the inclined surface grooves 21 and the center line of the first set of plates 6 are on the same vertical plane, and the anti-slip rubber pads 20 on both sides inside the inclined surface grooves 21 are symmetrically arranged;

[0031] Specifically, as Figure 1 、 Figure 3 and Figure 4As shown, during installation, the first set of plates 6 and the second set of plates 9 are attached to both ends of the pipeline, and the connecting plate 10 can connect the two sets of second set of plates 9 to keep the two sets of second set of plates 9 parallel.

While the driving gear 17 is rotating, it drives the microscope support cylinder 2 to descend through the transmission tooth block 18, so that the microscope support cylinder 2 is attached to the outside of the pipeline to be detected to ensure the detection effect of the microscope. During the detection process, there is a high damping between the knob 4 and the installation cylinder 1, and the driving gear 17 can be positioned through the knob 4, thereby improving the stability of the detection of the microscope support cylinder 2 and realizing the rapid adjustment of the height of the microscope to make it fit on the pipeline for detection.

[0036] Working principle: When the utility model is in use, during installation, the second sleeve plate 9 is attached to one end of the pipeline, and then the first sleeve plates 6 on both sides of the installation cylinder 1 are attached to the other end of the pipeline. Then, the connecting screw rod 8 is passed through the inside of the through hole 19 and screwed into the inside of the threaded sleeve 11, and the connecting screw rod 8 is driven to rotate by the rotary handle 15 through the turntable 14. After the connecting screw rod 8 is tightened, the first sleeve plate 6 and the second sleeve plate 9 can be positioned. The microscope is positioned by clamping the pipeline through the first sleeve plate 6 and the second sleeve plate 9. During installation, the first sleeve plate 6 and the second sleeve plate 9 are attached to both ends of the pipeline, and the connecting plate 10 can connect the two groups of second sleeve plates 9 to keep the two groups of second sleeve plates 9 parallel. The two anti-slip rubber pads 20 inside the inclined groove 21 are attached to the outside of the pipeline, which can improve the anti-slip performance and the stability after installation. Moreover, because the anti-slip rubber pads 20 are at an inclined angle, they can fit pipelines of different sizes, thus improving the versatility. After installing the device, the knob 4 can be rotated to drive the driving gear 17 to rotate. While the driving gear 17 rotates, the microscope support cylinder 2 is driven to descend by the transmission tooth block 18, so that the microscope support cylinder 2 fits on the outside of the pipeline to be detected to ensure the detection effect of the microscope. During the detection process, there is a high damping between the knob 4 and the installation cylinder 1, and the driving gear 17 can be positioned through the knob 4, thereby improving the stability of the detection of the microscope support cylinder 2.
