The utility model aims to provide a stair protection fixing device aiming at the prior art so as to solve the problems in the background art.
In order to solve the technical problems, the stair protection fixing device comprises a lower end plate, wherein an inclined section is arranged on one side of the outer wall of the lower end plate, a connecting rod piece is arranged on the inclined slope surface of the lower end plate, an upper end plate is arranged on the outer wall of the connecting rod piece, a torsion nut is arranged on the outer wall of the connecting rod piece, which is close to the upper end plate, and a protection sleeve rod is arranged on the top of the upper end plate.
Furthermore, the inner wall of the lower end plate is provided with a positioning hole, and the connecting rod piece is connected with the lower end plate through the positioning hole, so that the connecting rod piece is convenient to install.
Further, the end of the bottom of the connecting rod extending into the positioning hole is smaller than the outer end of the connecting rod, so that the connecting rod is prevented from penetrating through the lower end plate.
Furthermore, the top of the connecting rod piece is provided with threads, and the connecting rod piece is meshed with the torsion nut through the threads, so that the rotating and sliding of the toggle torsion nut are facilitated.
Furthermore, the bottom of the torque nut is mutually abutted with the top of the upper end plate, so that the upper end plate is conveniently fixed.
Compared with the prior art, the utility model has the beneficial effects that,
(1) Through being provided with lower end plate, connecting rod piece, upper end plate, torque nut and protection loop bar, realized the function of quick assembly to improved the convenience of operation, solved the time and energy that complex operation leads to, and overall structure is simple, the effectual manufacturing cost of having practiced thrift, and then satisfied people's work demand.
