[0023] The inner wall of the arc-shaped cylinder 3 is fixedly connected with a baffle 6, and the inner wall of the arc-shaped cylinder 3 is slidably connected with a first spring 7. One end of the first spring 7 is fixedly connected with the side wall of the adjacent baffle 6, and the other end of the first spring 7 is fixedly connected with the side wall of the adjacent short rod 5. Thus, when the short rod 5 is subjected to a reduced or disappeared tension, the short rod 5 can be quickly driven to move by the elastic action of the first spring 7, and the arc-shaped rod 4 forms a closed state with the arc-shaped cylinder 3.

[0024] The side wall of the short rod 5 is fixedly connected with a first pull rope 8. One end of the first pull rope 8 away from the short rod 5 is slidably connected through the wooden plate 1. The end of the first pull rope 8 away from the short rod 5 is fixedly connected with a first pull ring 9. The side wall of the wooden plate 1 is fixedly connected with a support plate 10. The side wall of the support plate 10 abuts against the side wall of the foam plate 2, so that the wooden plate 1 can quickly fix the foam plate 2 and support the foam plate 2 at the same time.

[0025] In this embodiment: when pouring the concrete strip foundation deformation joint, first, a deformation joint is reserved in the middle of each concrete strip foundation. The foam plate 2 and the wooden plate 1 that have been fixed need to be placed in the reserved deformation joint. The one side of the foam plate 2 is subjected to a concrete pouring operation. When the concrete pouring is completed and the foam plate 2 and the concrete are tightly attached together, the wooden plate 1 needs to be quickly disassembled. At this time, the first pull ring 9 is pulled, the first pull ring 9 drives the first pull rope 8 to move, the first pull rope 8 drives the short rod 5 to move, the short rod 5 drives the arc-shaped rod 4 to move and press the first spring 7, so as to expose the gap of the arc-shaped cylinder 3, so that the arc-shaped rod 4 no longer limits the foam plate 2. At this time, the foam plate 2 and the wooden plate 1 can be separated. The next segment of concrete pouring operation is performed at the position where the wooden plate 1 is originally located. The user can remove the foam plate 2 according to the actual situation or continue to keep it.

[0026] At this time, the wooden plate 1 can be repeatedly used. The wooden plate 1 is moved to the side wall of another foam plate 2. The first pull ring 9 is stretched, so that the arc-shaped rod 4 moves to the inside of the arc-shaped cylinder 3. After the side wall of the support plate 10 abuts against the side wall of the foam plate 2, the first pull ring 9 is loosened. At this time, under the elastic action of the first spring 7, one end of the arc-shaped rod 4 penetrates through the side wall of the foam plate 2 and is inserted into the inside of the arc-shaped cylinder 3 again, so as to quickly fix the wooden plate 1 and the foam plate 2.

A clamping plate 16 is fixedly connected with the side wall of the short column 15. Limiting plates are arranged on the side wall of the slide groove 13, so that the sliding plate 14 cannot move out of the inner wall of the slide groove 13, but the short column 15 and the clamping plate 16 are not limited.

[0028] The second spring 19 is fixedly connected to the inner wall of the wide slot 11, and the other end of the second spring 19 away from the inner wall of the wide slot 11 is fixedly connected to the side wall of the sliding plate 14, and the second spring 19 is telescopic deformed in the wide slot 11.
