[0006] A steel wire is bundled on the surface of the fixture, wherein a first end of the steel wire passes through the opening and is connected to the rod of any one of the screws.

[0007] A further improvement of the utility model is that a steel wire fixer for connecting the steel wire is installed on the screw, and the steel wire fixer includes a ring sleeved on the screw rod and a clamping plate fixed to the ring, and a clamping hole is provided on the clamping plate, and a clamping block for clamping in the clamping hole is provided at the first end of the steel wire, and the second end of the steel wire passes through the opening and passes out of the fixer.

[0008] A further improvement of the utility model is that the screw rod portion includes a threaded section and a sleeve section connected between the threaded section and the bolt head, the sleeve section has a rectangular cross section, and the inner annular surface of the sleeve ring matches the sleeve section.

[0009] A further improvement of the utility model is that the number of the steel wires is at least two, the first ends of the two steel wires respectively pass through the openings and are connected to the corresponding screw rods, and the second ends of the two steel wires are bundled together on the surface of the fixer.

[0010] The utility model provides a front shell and a rear shell of the fixer to accommodate the cross portion of the cross steel bars in the accommodating space of the fixer, and fixes the front shell and the rear shell of the fixer with screws and threaded tubes, so that the structure is stable. At the same time, one end of the steel wire is extended into the interior of the fixer and connected to the screw, and the other end is tied outside the fixer to reinforce the structure. The connection between the steel wire and the screw of the utility model is inside the fixer, which can effectively prevent the stability of the structure from being affected by external erosion of the connection part.
