[0043] At the same time, each semicircular fixed plate 130 is provided with at least one arc-shaped sliding assembly; the arc-shaped sliding assembly also includes a connecting block 530, a lower push block 480, an upper push block 590 and a fixing component; the connecting block 530 is arranged on the sixth outer wall 510; the lower push block 480 is slidably connected to the connecting block 530, and the lower push block 480 is above the connecting block 530; a first spring 550 is arranged between the lower push block 480 and the connecting block 530; the first spring 550 is always in a compressed state, and the elastic force of the first spring 550 makes the lower push block 480 fit and contact with the lower surface of the arc-shaped blocking arm 160; the upper push block 590 is hinged to the upper surface 520 of the lower push block, and the upper push block 590 can be rotated to fit and contact with the upper surface of the arc-shaped blocking arm 160; the fixing component is used to fix the position of the upper push block 590 relative to the lower push block 480, so that the upper push block 590 and the lower push block 480 are clamped and fixed to the arc-shaped blocking arm 160.

[0044] Specifically, when it is necessary to slide the support slider 170 to adjust the position, the fixing component is released so that the upper stop block 590 and the lower stop block 480 are no longer clamped and fixed to the arc-shaped stop arm 160, and the support slider 170 can slide freely; when the support slider 170 slides to the target position, the position of the upper stop block 590 relative to the lower stop block 480 can be fixed by the fixing component, so that the upper stop block 590 and the lower stop block 480 are clamped and fixed to the arc-shaped stop arm 160, thereby fixing the position of the support slider 170 relative to the semicircular fixed plate 130.

[0045] In addition, the arc-shaped sliding assembly also includes a first sliding rod 540, a first baffle 560, a second rotating shaft 580 and a supporting column 570; the first sliding rod 540 is slidably arranged in the connecting block 530; one end of the first sliding rod 540 is connected to the upper stop block 590, and the other end of the first sliding rod 540 is connected to the first baffle 560; the lower stop block 480 and the first baffle 560 are respectively located on both sides of the connecting block 530; the first spring 550 is sleeved on the first sliding rod 540; the second The rotating shaft 580 is fixedly arranged in the middle of the upper block 590; the number of the supporting columns 570 is 2, and the 2 supporting columns 570 are both arranged on the upper surface 520 of the lower block; the two ends of the second rotating shaft 580 are rotatably connected to the 2 supporting columns 570 respectively; the second rotating shaft 580 is parallel to the upper surface 520 of the lower block; a torsion spring (not shown) is arranged at the second rotating shaft 580, and the torsion force of the torsion spring makes the upper block 590 have a tendency to move away from the arc-shaped blocking arm 160 (as shown in the attached figure). Figure 3 As shown, the torsion force of the torsion spring makes the upper stop block 590 have a tendency to rotate clockwise); the upper surface 520 of the lower stop block is parallel to the upper surface of the arc-shaped blocking arm 160.

[0046] The above technical solution improves the structure of the arc-shaped sliding assembly, that is, the upper surface 520 of the lower stop block slides and fits in contact with the lower surface of the arc-shaped stop arm 160 under the action of the first spring 550; but the contact here, as well as the fitting contact between the fifth outer wall 490 and the lower surface of the arc-shaped stop arm 160, will not hinder the sliding of the support slider 170 relative to the arc-shaped slide rod 150.

[0047] At the same time, the above-mentioned fixed components include a rotating block 610, a rotating arm 630, a second slide bar 650, a second baffle 660, an annular baffle 670 and a second spring 640; a groove 680 is provided on the upper surface 520 of the lower stop block; the groove 680 is rectangular in the top view; a second through hole 690 which passes through the groove 680 is also provided on the lower surface of the lower stop block 480; the central axis of the second through hole 690 is perpendicular to the upper surface 520 of the lower stop block; the rotating block 610 is a rectangular parallelepiped and can be fitted into the groove 680; one end of the second slide bar 650 is connected to the lower surface of the rotating block 610; the second slide bar 650 is rotatably penetrated in the second through hole 690, and the other end of the second slide bar 650 extends downward from the second through hole 690; one end of the second slide bar 650 extending downward from the second through hole 690 is connected to the second baffle 660, and the second baffle 660 is perpendicular to the second slide bar 650; the annular baffle 670 is movably mounted on the second slide bar 650, and the annular baffle 670 is between the second baffle 660 and the lower stop block 480; one end of the second spring 640 is connected to the lower surface of the lower stop block 480, the other end of the second spring 640 is connected to the annular baffle 670, and the second spring 640 is mounted on the second slide bar 650; the second spring 640 is always in a compressed state, and the elastic force of the second spring 640 makes the annular baffle 670 abut against the second baffle 660, so that the second slide bar 650 has a tendency to move downward.

[0048] The upper surface 520 of the lower stopper is also provided with a long waist groove 620 connected to the groove 680; the rotating arm 630 is connected to the rotating block 610; when the rotating block 610 rotates to completely overlap with the groove 680 in the top view, the elastic force of the second spring 640 causes the rotating block 610 to completely embed into the groove 680 (at this time, the lower surface of the rotating block 610 is in close contact with the inner bottom wall of the groove 680); when the rotating block 610 is completely embedded in the groove 680, the rotating arm 630 is completely embedded in the long waist groove 620 (at this time, the rotating arm 630 extends outward from the lower stopper 480) ; The rotating block 610 can also extend upward from the groove 680 and rotate until the lower surface of the rotating block 610 is in contact with the upper surface 520 of the lower abutment block; when the lower surface of the rotating block 610 is in contact with the upper surface 520 of the lower abutment block, the upper surface of the rotating block 610 is in contact with the lower surface of the upper abutment block 590 (at this time, the rotating block 610 and the arc-shaped blocking arm 160 are respectively located on both sides of the second rotating shaft 580), and the upper abutment block 590 is in contact with the arc-shaped blocking arm 160; a rubber layer (not shown) is provided on one side of the upper abutment block 590 for abutting the arc-shaped baffle.

[0049] Through the above technical scheme, the structure and function of the fixing component are improved; when it is necessary to fix the upper butt block 590 and the lower butt block 480 to the arc-shaped blocking arm 160, the operator holds the rotating arm 630 and pulls the rotating block 610 upward to make the rotating block 610 extend out of the groove 680, and then rotates the rotating block 610 to make the lower surface of the rotating block 610 fit and abut against the upper surface 520 of the lower butt block. At this time, the upper surface of the rotating block 610 abuts against the lower surface of the upper butt block 590, and then makes the side of the upper butt block 590 away from the rotating block 610 fit and press against the upper surface of the arc-shaped blocking arm 160, so that the upper butt block 590 and the lower butt block 480 are clamped and fixed to the arc-shaped blocking arm 160 (as shown in the attached figure). Figure 2 When the arc-shaped retaining arm 160 is no longer needed to be clamped, the rotating arm 630 is held by hand to rotate the rotating block 610, and the rotating block 610 is rotated until it completely overlaps with the groove 680 in the top view. At this time, the elastic force of the second spring 640 makes the rotating block 610 completely embedded in the groove 680, and the rotating arm 630 is completely embedded in the long waist groove 620; in this way, the rotating block 610 no longer supports the upper block 590, and the upper block 590 is no longer in contact with the arc-shaped retaining arm 160 under the action of the torsion spring (as shown in the attached figure). Figure 3 As shown), the arc-shaped blocking arm 160 is no longer clamped and fixed.

[0050] In addition, two second connecting plates 140 are respectively provided at both ends of the semicircular fixing plate 130; the two second connecting plates 140 of the same semicircular fixing plate 130 are in the same plane; when the two semicircular fixing plates 130 are buckled with each other, the two second connecting plates 140 of one semicircular fixing plate 130 correspond one to one with the two second connecting plates 140 of the other semicircular fixing plate 130; the two corresponding second connecting plates 140 are directly opposite to each other, and bolts are screwed in between the two corresponding second connecting plates 140, so that the two semicircular fixing plates 130 are fixedly buckled with the pile foundation 110. Through the above technical solution, the fixed connection solution between the semicircular fixing plates 130 is improved.
