The side wall of the slider 41 at the inner end of the bracket 2 is provided with a clearance opening 413 which is matched with the inner pin a, wherein the height of the clearance opening 413 in the up-down direction is slightly larger than the diameter of the inner pin a connecting the clamping power mechanism 42 and the bracket square tube 22, so that the inner pin a can enter the clearance opening 413, the length of the clearance opening 413 in the front-back direction can be used for enabling the end of the slider 41 facing the inner side of the bracket square tube 22 to avoid the inner pin a and slide to the middle of the bracket square tube 22.
The clamping power mechanism 42 is a telescopic oil cylinder, the clamping power mechanism 42 is arranged in the bracket square tube 22, the cylinder body is connected with the middle part of the bracket square tube 22 through an inner side pin shaft a, the telescopic rod extends out of the bracket square tube 22 and is connected with the sliding piece 41 through an inner side pin shaft a, and the clamping power mechanism 42 is used for driving the sliding piece to slide in the front-back direction. The clamping power mechanism 42 is arranged in the bracket square tube 22, so that the extending and contracting direction of the clamping power mechanism 42 can be limited, the clamping power mechanism 42 can only extend and contract along the extending direction of the bracket square tube 22, and the oil cylinder can be protected.
As shown in fig. 9, the clamping seat 43 is fixedly arranged on the sliding member, and the front end and the rear end of the clamping seat 43 are respectively provided with a claw 44. The claw 44 facing the inside of the bracket 2 is flush with the end of the slider 41 facing the inside of the bracket 2. When two sliding pieces 41 positioned on the same bracket square tube 22 are slid towards each other to the middle part of the bracket 2, the arch rings 61 of a plurality of arch segments 6 can be clamped and fixed by the cooperation of two clamping claws 44 on the two sliding pieces 41.
The distance L2 (see fig. 9) between the two ends of the two claws 44 on the clamping seat is smaller than the distance between the adjacent arch rings L1 (see fig. 3) in the arch sections 6, so that the sliding part can enter between the two arch rings of the arch sections 6.
In other embodiments, as shown in fig. 10, two sliding members 41 on the same side of the bracket may slide towards the outside of the bracket 2, i.e. the sliding member 41 on the front side slides forward, and the sliding member on the rear side slides backward, so that the claws 44 on the sliding member clamp the arch rings 61 of the arch segments 6 outwards.
Referring to fig. 4 and 11, the clamping devices 4 are provided with four, two of the clamping devices 4 are provided on the bracket square tube 22 located on the left side of the bracket 2, are oppositely provided in the front-rear direction, and the two clamping devices 4 are combined as a group to mutually cooperate and clamp the left side of the arch ring 61; the other two clamping devices 4 are arranged on the bracket square tube 22 positioned on the right side of the bracket 2, are oppositely arranged in the front-rear direction, and are used as a group to mutually match and clamp the right side of the arch ring 61.

By arranging the antiskid plates 24 on the bracket square tube 22, the antiskid plates 24 penetrate through the antiskid holes 411 on the sliding piece 41, the top surface of each antiskid plate 24 is higher than the top surface of the corresponding sliding piece 41, a plurality of arch segments 6 can be supported by the antiskid plates 24, and the friction force can be increased by arranging the convex stripes on the antiskid plates 24, so that the arch segments 6 can be prevented from sliding and inclining on the bracket square tube 22; the slide 41 is provided with the anti-slip holes 411 so as to avoid the anti-slip plate 24 when the slide 41 slides, thereby preventing the slide 41 from being affected.
By providing the escape openings 412 on the side surfaces of the sliding members 41, the bracket connection pipe 21 can be avoided when the sliding members 41 slide inward along the bracket square pipe 22, so that the sliding members 41 respectively positioned on both sides of the bracket square pipe 22 can slide to the middle part of the bracket square pipe 22, and the claws 44 arranged on the two sliding members 41 clamp the arch rings 61 on the arch segments 6 to fix the arch segments 6. By providing the receiving openings 221 in the left and right side walls at both ends of the bracket square tube 22, when the slider 41 slides inward of the bracket 2, the outer pin b connected to the slider 41 and the clamping power mechanism 42 can be made to enter the receiving openings 221, the slider 41 can slide to the middle of the bracket square tube 22 toward one end inside the bracket 2, the claws 44 provided on the slider 41 can clamp the arch rings 61 on the arch segments 6, and the arch segments 6 can be fixed.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims.
