Since the second connecting block 28 and the bottom of the first extrusion adjustment arm 20 are limited, when the extrusion control plate 23 is pulled, the symmetrically arranged arc-shaped clamping ring 26 can be synchronously moved toward the middle of the clamping fixing device 19 through the second extrusion adjustment arm 22 and the first extrusion adjustment arm 20. At this time, the sliding support plate 25 pulls the buffer return spring 24 to extend and slide inside the two ends of the arc-shaped clamping ring 26.

[0044] When implementing this embodiment, auxiliary internal connecting pipe fittings 2 are fixedly arranged at both ends of the extension tube 4, and the auxiliary internal connecting pipe fittings 2 are sealed and clamped with the auxiliary external connecting pipe fittings 3 arranged outside, so that the extension tube 4 can be conveniently clamped and spliced ​​for use, so that the extension tube 4 can be simply operated and installed during the installation process. Two extrusion limit devices 8 are arranged in the middle of the extension tube 4, and the bottom clamping seat 11 and the top clamping seat 16 in the extrusion limit device 8 can be used to squeeze and clamp the outer wall of the extension tube 4, so that the extension tube 4 is not easy to slide and shake during the process of fixed connection and use. By setting a second stable limiting device 6, the clamping and fixing device 19 in the second stable limiting device 6 can be used to clamp and limit the extension tube 4, so that the extension tube 4 will not be displaced during use, ensuring that the extension tube 4 will not slide or displace during use, and will be firm and stable to use without offset or falling off.

[0045] Example 2

[0046] On the basis of Example 1, Fig.10 As shown, a rubber protective sheet 29 is fixedly mounted on the outside of the arc-shaped limiting block 27 by bolts.

[0047] When implementing this embodiment, since the rubber protective sheet 29 is fixedly installed on the outside of the arc-shaped limit block 27 by bolts, when the arc-shaped limit block 27 is clamped in the gap between the clamping baffle plates 7 by the rubber protective sheet 29, not only can the extension tube 4 be firmly clamped, but the outer wall of the extension tube 4 can also be protected, so that the arc-shaped limit block 27 will not squeeze and damage the outer wall of the extension tube 4.

[0048] Working principle: First, the auxiliary inner connecting pipe fittings 2 fixedly connected to the two ends of the extension tube 4 are clamped and connected with the auxiliary outer connecting pipe fittings 3 set on the external equipment, so that the extension tube 4 can be fixedly installed and used. After the extension tube 4 is fixedly installed, the hydraulic cylinders 18 in the two second stable limiting devices 6 are started, and the extrusion control plate 23 is pulled upward by the hydraulic cylinders 18. Since the second connecting block 28 and the bottom of the first extrusion adjustment arm 20 are limited, when the extrusion control plate 23 is pulled, the symmetrically arranged arc-shaped clamping ring 26 can be synchronously moved toward the middle of the clamping fixture 19 through the second extrusion adjustment arm 22 and the first extrusion adjustment arm 20. At this time, the sliding support plate 25 pulls the buffer reset spring 24 to extend on the arc-shaped clamping ring The two ends of 26 slide inside, at this time, the arc-shaped limit block 27 is clamped into the gap between the clamping baffle plate 7, and squeezes the outer wall of the extension tube 4, so as to limit the extension tube 4, so that the extension tube 4 will not be displaced and moved during use, and the fastening bolt 13 is screwed to make the fastening bolt 13 rotate and move the internal threads of the second fastening connecting plate 14 and the first fastening connecting plate 12, at this time, the fastening bolt 13 can be squeezed to make the top clamping seat 16 slide downward along the limited sliding support frame 15, so that the extension tube 4 is squeezed and clamped between the top clamping seat 16 and the bottom clamping seat 11, so as to clamp and limit the middle part of the extension tube 4 again, and finally both ends and the middle part of the extension tube 4 are clamped, limited and fixed. The installed extension tube 4 is stable and firm during use, and the hydraulic cylinder 18 presses the extrusion control plate 23 downward. At this time, the buffer reset spring 24 resets, so that the arc-shaped clamping ring 26 moves away from each other, so that the arc-shaped limit block 27 is separated from the gap between the clamping baffle plates 7. Since the rubber protective sheet 29 is fixedly installed on the outside of the arc-shaped limit block 27 by bolts, when the arc-shaped limit block 27 is clamped in the gap between the clamping baffle plates 7 by the rubber protective sheet 29, not only can the extension tube 4 be firmly clamped, but also the outer wall of the extension tube 4 can be protected, so that the arc-shaped limit block 27 will not squeeze and damage the outer wall of the extension tube 4. The device is fixedly provided with auxiliary inner The connecting pipe 2 is sealed and fixedly connected between the auxiliary inner connecting pipe 2 and the auxiliary outer connecting pipe 3 arranged outside, so that the extension pipe 4 can be conveniently fixed and spliced ​​for use, so that the extension pipe 4 can be simply operated and installed during the installation process. By setting two extrusion limit devices 8 in the middle of the extension pipe 4, the bottom fixing seat 11 and the top fixing seat 16 in the extrusion limit device 8 can be used to squeeze and clamp the outer wall of the extension pipe 4, so that the extension pipe 4 is not easy to slide and shake during the fixed connection and use. By setting a second stable limiting device 6, the clamping and fixing device 19 in the second stable limiting device 6 can be used to fix and limit the extension pipe 4, so that the extension pipe 4 will not be displaced during use.It ensures that the extension tube 4 will not slide or shift during use, and is firm and stable to use without deflection or falling off.
