Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] See also Figures 1 to 4The utility model provides a technical solution: a fixing device for the lower support base of a cantilevered formwork frame, comprising a bracket 1 and two embedded tubes 2, a first clamping block 3 being fixed on the inner side of the embedded tube 2, two mounting holes 4 being provided on the outer side of the bracket 1, an inserting rod 5 being fixed inside the mounting hole 4, an installation groove 6 being provided on one end of the inserting rod 5 close to the embedded tube 2, a through groove 7 being provided on the inner bottom of the mounting groove 6, an elastic rod 8 being fixed on the inner side of the mounting groove 6, a second clamping block 9 being fixed on one end of the elastic rod 8, a second inclined surface 17 being provided on one end of the second clamping block 9, a handle 18 being further fixed on the outer side of the circumference of the eccentric block 14, a protrusion 10 being fixed on one side of the elastic rod 8 close to the first clamping block 3, a first inclined surface 11 being provided on one side of the protrusion 10, a movable rod 12 being slidably connected to the inside of the inserting rod 5, and the movable rod 12 One end of the rod 5 slides in contact with the outer side of the first inclined surface 11, and a groove 13 is provided at the end of the insertion rod 5 away from the embedded tube 2. The inner side of the groove 13 is rotatably connected with an eccentric block 14. The outer side of the eccentric block 14 slides in contact with the other end of the movable rod 12, and a first clamping groove 15 is provided on the outer side of the circumference of the eccentric block 14. A second clamping groove 16 is also provided on the outer side of the circumference of the eccentric block 14. The first clamping block 3 has a triangular structure, and one end of the insertion rod 5 is plugged into and matched with the inner side of the embedded tube 2. The outer size of the insertion rod 5 is the same as the inner size of the embedded tube 2. The first clamping groove 15 and the second clamping groove 16 are symmetrically arranged. The inner side of the first clamping groove 15 is snap-fitted with the other end of the movable rod 12, and the inner side of the second clamping groove 16 is snap-fitted with the other end of the movable rod 12. The second clamping block 9 is snap-fitted with the first clamping block 3;

[0023] When building a wall, the embedded tube 2 is buried in advance. After the wall is formed, the rod 5 on the bracket 1 is inserted into the embedded tube 2. During this process, the second inclined surface 17 on the second clamping block 9 contacts the first clamping block 3 on the embedded tube 2, and the two slip, causing the elastic rod 8 to bend, thereby allowing the second clamping block 9 to pass over the first clamping block 3 and then engage with it, thereby quickly completing the fixed installation of the bracket 1. When it is necessary to remove the support base, the eccentric block 14 is driven to rotate by the handle 18. During this process, the eccentric block 14 pushes the movable rod 12 to move, and the movable rod 12 squeezes the first inclined surface 11 on the protrusion 10, and slips between the two, causing the elastic rod 8 to The second clamping block 9 is bent, thereby separating the second clamping block 9 from the first clamping block 3. At the same time, the second clamping groove 16 on the eccentric block 14 is engaged with the other end of the elastic rod 8, thereby fixing the position of the elastic rod 8, so that the elastic rod 8 always keeps the state of squeezing the protrusion 10, so that the second clamping block 9 is always separated from the first clamping block 3. After that, the second clamping block 9 on the other side is opened to separate the bracket 1 from the embedded tube 2. Through the above process, the support base can be installed and disassembled quickly and conveniently, which solves the problem of the existing support base fixing device under the cantilever formwork frame, which is time-consuming and labor-intensive, and reduces work efficiency, by placing expansion bolts for fixing after punching holes in the wall.

[0024] The specific usage and function of this embodiment: When building a wall, the embedded tube 2 is pre-buried. After the wall is formed, the rod 5 on the bracket 1 is inserted into the embedded tube 2. During this process, the second inclined surface 17 on the second clamping block 9 contacts the first clamping block 3 on the embedded tube 2, and the two slip, causing the elastic rod 8 to bend, thereby allowing the second clamping block 9 to pass over the first clamping block 3 and then engage with it, thereby quickly completing the fixed installation of the bracket 1. When it is necessary to remove the support base, the eccentric block 14 is driven to rotate by the handle 18. In this process, In the process, the eccentric block 14 pushes the movable rod 12 to move, and the movable rod 12 squeezes the first inclined surface 11 on the protrusion 10, and slippage occurs between the two, causing the elastic rod 8 to bend, thereby separating the second block 9 from the first block 3. At the same time, the second card groove 16 on the eccentric block 14 is engaged with the other end of the elastic rod 8, thereby fixing the position of the elastic rod 8, so that the elastic rod 8 always keeps squeezing the protrusion 10, so that the second block 9 is always separated from the first block 3. After that, the second block 9 on the other side is opened to separate the bracket 1 from the embedded tube 2.
