The front end of the screw rod 31 is connected to an extension rod 32, and the two sides of the extension rod 32 are welded with limited insertion rods 33. The mounting seat 2 is fixed above the mounting plate 12 by bolts. The straight square tube 23 and the lateral square tube 24 cooperate with the extension rod 32 to support the reinforced concrete beam 11. The subsequent disassembly and assembly only needs to unscrew the bolts that fix the mounting seat 2 and the mounting plate 12. In this way, the device can be disassembled and reused, which can effectively reduce the construction cost. The mounting seat 2 and the mounting plate 12 are fixed by symmetrical bolts. The symmetrical bolts The bolt can make the connection between the mounting seat 2 and the mounting plate 12 more convenient and quick. The straight square tube 23 is provided with a slide groove near the position of the limit plug rod 33, and the slide groove can limit and guide the sliding of the limit plug rod 33. The side square tube 24 and the straight square tube 23 are arranged perpendicular to each other to form a cross-shaped structure, which can make the device support the reinforced concrete beam 11 more reliably. The straight square tube 23 is installed with a bearing near the hand crank 3, and the bearing can effectively reduce the friction when the hand crank 3 rotates. The hand crank 3 is hollow, and the hand crank 3 is hollow. The rocker 3 and the lead screw 31 are arranged with the axis coincident, and the hollow arrangement can facilitate the lead screw 31 to enter the interior of the hand rocker 3.
