[0027] This device has the effect of preventing concrete from entering the interior of the electrical conduit and fixing the electrical conduit, specifically:

[0028] The cylinder 2 is a cylindrical structure with round holes at both ends. The cylinder 2 is installed on the surface of the box body 1, and the four surfaces of the box body 1 are all provided with cylinders 2. The structures of the four cylinders 2 are completely consistent. A slider 3 is penetrated through the surface of one side of the cylinder 2. The slider 3 is slidably connected to the inner wall of the cylinder 2. A block 9 is provided at one end of the slider 3. The surface of the block 9 is a spherical convex surface. A push rod 4 is connected to one side of the slider 3, and gear blocks are provided on both sides of the push rod 4. A gear 5 is provided for rotation inside the cylinder 2. One side of the gear 5 is meshed with the gear block on the surface of the push rod 4. A rack 6 is provided on the other side of the gear 5. The rack 6 is slidably arranged It is mounted on the inner wall of the cylinder 2, and the gear 5 is meshed with the rack 6. A push block 7 is arranged at one end of the rack 6, and the push block 7 penetrates the side surface of the cylinder 2. A clamping block 8 is slidably arranged on the side surface of the cylinder 2. The clamping block 8 is a semicircular ring structure, and a convex block is arranged on one side of the clamping block 8 to contact the push block 7. The gear 5, the rack 6, the push block 7 and the clamping block 8 are symmetrically arranged inside the cylinder 2. The two clamping blocks 8 constitute a circular ring structure. A lever 11 is penetrated on the upper surface of the box body 1, and the lever 11 is slidably connected to the upper surface of the box body 1. The lower end of the lever 11 is connected to a push rod 10, and one end of the push rod 10 is aligned with the push rod 1 4.

[0029] like Figure 1-Figure 4 As shown, taking the cylinder 2 on the right side of the box body 1 as an example, when the electrical conduit needs to be fixed, the conduit is brought into contact with the block 9 from the right side of the cylinder 2, so that the block 9 is located on the inner wall of the electrical conduit to block the open end of the conduit, to prevent cement leakage from blocking the conduit, thereby affecting the qualified rate of the pre-buried electrical conduit, and the electrical conduit is continued to be pushed to the left, and the conduit pushes the slider 3 to move to the left on the inner wall of the cylinder 2, and the slider 3 drives the push rod 4 to move to the left, and the upper and lower parts of the push rod 4 are respectively in contact with the gear 5, driving the gears 5 on both sides to rotate, and the rotation of the gear 5 drives the rack 6 to move, and since the push rod 4 and the rack 6 are respectively meshed with the two sides of the same gear 5, The movement directions of the rack 6 and the push rod 1 4 are opposite.
