[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a formwork support device for the edge of a water-stabilized crushed stone base, including a template 1 and a support frame 2. A rotating shaft 3 is movably connected inside the support frame 2. Guide grooves 4 are provided at both ends of the outer wall of the rotating shaft 3. Clamping plates 5 are movably connected to both sides inside the support frame 2. Gaskets 6 are fixedly connected to the opposite side of the two clamping plates 5. A protrusion 7 is fixedly connected to the side of the clamping plate 5 near the rotating shaft 3. A rotating rod 9 is fixedly connected to the middle of the rotating shaft 3. A round rod 10 is movably connected inside the rotating rod 9. A spring 11 is movably sleeved on the outside of the round rod 10. A base 12 is fixedly connected to the end of the round rod 10 away from the support frame 2. Circular grooves 13 are provided on both sides of the template 1. A bolt assembly 14 is provided in the middle of the support frame 2.

[0022] Adopt the above scheme: through the rotating rod 9 drive rotating shaft 3 rotates downward, and then make the protruding block 7 along the track of guide groove 4 sliding, and because the two guide grooves 4 are opposite, therefore, the protruding block 7 can only drive two clamping plates 5 to move horizontally and linearly under the limit of sliding groove 8, through the design of gasket 6, so that the clamping plate 5 moves, and drives two gaskets 6 to abut against the side wall of two templates 1 respectively, and extrudes two templates 1 to move towards each other, then, through the rotating rod 9 rotates and drives the base 12 to abut against the ground, and fixes the base 12 on the ground through the anchor, so as to fix the position of the rotating rod 9 after rotation, and then it is convenient to tightly splice and fix two templates 1.

[0023] As shown in Figures 2 to 4 , the two guide grooves 4 are opposite, the curvature of the guide groove 4 is ninety degrees, the protruding block 7 is movably connected in the guide groove 4, the gasket 6 is made of rubber material, the middle part of the support frame 2, the clamping plate 5 and the gasket 6 is provided with a circular hole with the same diameter as the circular groove 13, and the template 1 and the support frame 2 are fixedly connected through the bolt assembly 14.

[0024] Adopt the above scheme: the gasket 6 is made of rubber material, which can effectively buffer the pressure, avoid the template 1 directly bearing the rigid impact, and improve the stability between the template 1 and the gasket 6.

[0025] As shown in Figure 2 and Figure 3 , the inner wall of the support frame 2 is provided with a sliding groove 8 matched with the clamping plate 5, the sliding groove 8 is used for limiting the clamping plate 5 in horizontal direction, the rotating rod 9 rotates around the rotating shaft 3, the two ends of the spring 11 are fixedly connected with the rotating rod 9 and the circular rod 10 respectively, the side wall of the support frame 2 is provided with a square groove matched with the rotating rod 9, and one side of the base 12 is provided with a handle.

[0026] Adopt the above scheme: through the design of the circular rod 10 and the spring 11, the length of the rotating rod 9 after rotation may not be able to directly drive the base 12 to abut against the ground, at this time, through the design of the circular rod 10, the length between the rotating rod 9 and the base 12 is extended, so that the base 12 abuts against the ground smoothly, when the template 1 is used and needs to be disassembled, at this time, the base 12 is fixed with the ground, then, the circular rod 10 drives the base 12 to reset under the action of the spring 11, so as to facilitate the next use of the device.

[0027] The working principle and use process of the utility model: when two templates 1 need to be spliced, at this time, the operator places the support frame 2 between the intersection of the two templates 1, and abuts the top of the support frame 2 with the top of the inner cavity of the template 1, then the operator passes the bolt assembly 14 through the side wall of the two templates 1 through the round groove 13 and the round hole opened on the surface of the support frame 2, and then fixes the position of the support frame 2, then the operator holds the handle on one side of the base 12 and presses the base 12 downward, so as to drive the round rod 10 and the rotating rod 9 outside the round rod 10 to rotate downward together, while the rotating rod 9 rotates, the rotating shaft 3 is driven to rotate in the same direction, so that the two protruding blocks 7 slide along the trajectories of the two opposite guide grooves 4 respectively, and because the sliding groove 8 limits the horizontal movement of the clamping plate 5, the protruding block 7 can only drive the two clamping plates 5 to move horizontally and linearly towards each other, the clamping plate 5 moves together with the gasket 6, so that the two gaskets 6 abut with the side wall of the two templates 1 respectively and press the two templates 1 to move towards each other, so that the two templates 1 are connected more tightly, when the rotating rod 9 rotates to the predetermined position, the base 12 abuts with the ground at this time, then the operator fixes the base 12 on the ground by the anchor, and then fixes the position of the rotating rod 9 after rotation, so as to facilitate the splicing and fixing of the two templates 1.
