The upper surface of the strip-shaped plate is fixedly provided with a semi-cylinder corresponding to the middle of the arc-shaped plate, and the front end surface and the rear end surface of the semi-cylinder are fixedly provided with semicircular limiting plates. Two sliding blocks are arranged on the arc surface of the semi-cylinder in a sliding fit mode, and guide blocks in sliding fit with the limiting plates are fixedly arranged at the front end and the rear end of each sliding block. The slider is fixedly provided with a guide sleeve, a telescopic plate is arranged in the guide sleeve in a sliding fit mode, and the end portion of the telescopic plate is fixedly provided with a mounting column which is arranged along the front-back direction. The positions of the guide sleeve and the telescopic plate are adjusted by pushing the sliding block to slide on the semi-cylinders, and the telescopic length of the telescopic plate in the guide sleeve is adjusted, so that the installation column is ensured to be adjusted in the position of the bottom surface of the arc plate under the state of being tightly attached to the bottom surface of the arc plate, and the support for different positions of the arc plate is realized. The front end face of the mounting column is aligned with the rear end face of the front end plate, and the rear end face of the mounting column is aligned with the front end face of the rear end plate. Set up the first screw hole of arranging along the fore-and-aft direction on the terminal surface around the erection column, set up a plurality of and first screw hole complex second screw hole on front end plate and the back end plate, the screw post is installed to second screw hole internal rotation. Make the screw thread post twist in second screw hole and first screw hole through rotating the screw thread post to wholly play the fixed action to erection column, expansion plate and uide bushing, give semicylinder and bar through erection column, expansion plate and uide bushing with the pressure transmission of arc, thereby play reinforced (rfd) effect to the arc.
The fixing mechanism comprises a square block, a square groove, a first oil groove, a sealing plate, an ejector rod, a limiting block, a first sliding groove, a first clamping block, a second sliding groove, a fixing block, a first spring, a second clamping block, a second spring and a magnet rod. Square piece fixed mounting is on arc board bottom end face, and the upper surface of strip shaped plate is seted up the square groove of mutually supporting with square piece. A first oil groove is formed in the square block, a sealing plate is arranged at one end of the first oil groove in a vertical sliding fit mode, and an ejector rod is fixedly arranged on the bottom face of the square groove in a vertical position corresponding to the sealing plate. The other end of the first oil groove is horizontally matched with a limiting block in a sliding manner, and a limiting groove matched with the limiting block is formed in the side wall of the square groove. One surface of the limiting block matched with the limiting groove is an inclined surface, and the other surface is a horizontal surface. The square block and the arc plate are internally positioned above the square groove and vertically provided with a first sliding groove communicated with the square groove, and the top surface of the sealing plate is fixedly connected with a first clamping block in sliding fit with the first sliding groove through a connecting rod. The top surface of the first clamping block is an arc surface, and the bottom surface of the first clamping block is a horizontal plane. The side wall of the first sliding groove is horizontally provided with a second sliding groove. A fixed block is fixedly arranged in the second sliding groove, and one end of the fixed block is connected with an iron second clamping block through a first spring. The top surface of the second fixture block is a horizontal surface, and the bottom surface of the second fixture block is an arc surface. The other end of the fixed block is connected with a magnet rod in sliding fit with the second sliding groove through a second spring. The installation process between the strip-shaped plate and the arc-shaped plate is as follows: the upper surface of the strip-shaped plate is attached to the end surface of the bottom of the arc-shaped plate, so that the square block is inserted into the square groove. In the process, the ejector rod pushes the sealing plate to move upwards along the first oil groove and extrude hydraulic oil in the first oil groove, and the hydraulic oil pushes the limiting block to be inserted into the limiting groove formed in the side wall of the square groove after being extruded.

Make screw thread post 13 twist in second screw hole 12 and first screw hole 11 through rotating screw thread post 13 to wholly play the fixed action to erection column 10, expansion plate 9 and uide bushing 8, give semicylinder 4 and bar 2 through erection column 10, expansion plate 9 and uide bushing 8 with the pressure transmission of arc 101, thereby play reinforced (rfd) effect to arc 101. When the single mounting column 10, the telescopic plate 9 and the guide sleeve 8 are disassembled, the threaded column 13 is only required to be screwed, so that the threaded column 13 is withdrawn from the first threaded hole 11.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
