By above technical scheme, the top cap upper surface of described jack is cambered surface, and in cambered surface, circumferentially direction is provided with U-shaped groove.
By above technical scheme, the angle of described mounting ear and platform steel plate is 65 ° ~ 80 °.
Contrast prior art, beneficial features of the present invention is:
1), when laying reinforcing bar, mounting ear is plugged pin and is fixed muscle body both sides, then to jack pressurization, top cap pushes up outward, reinforcing bar is bent, can reinforcing bar be made fast and effectively to bend;
2), platform steel plate is provided with two to the mounting ear about jack symmetry, when laying reinforcing bar, mounting ear is plugged pin be fixed reinforcing bar both sides, the hand-held dowel bending machine of workman is not needed to fix in bar bending process, safer, after reinforcing bar bending terminates, extract pin and can take off dowel bending machine, easy to use;
3), the top cap upper surface of jack is cambered surface, and in cambered surface, circumferentially direction is provided with U-shaped groove, and reinforcing bar is bent along U-shaped groove, can prevent from sliding in bar bending process, and efficiency is high, security is high;
4), platform steel plate lower end is provided with to be connected with between the triangular steel plate of support platform steel plate, two pairs of mounting ears and two pairs of mounting ears can be stoped to be provided with the end stiffener be connected with platform steel plate for strengthening mounting ear because of stressed outwardly limit stiffener, often pair of mounting ear root, ensure that rigidity and the intensity of dowel bending machine, security is high.

Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.
Please refer to Fig. 1 to Figure 10, embodiment of the present invention dowel bending machine, it comprises jack 1, the cylinder body 1-1 upper surface arranged outside of described jack 1 has platform steel plate 2, described platform steel plate 2 lower end is provided with and connects jack cylinder body 1-1 with the triangular steel plate 3 of support platform steel plate 2, described platform steel plate 2 is provided with two to the mounting ear 4 about jack 1 symmetry, limit stiffener 5 is connected with between two pairs of described mounting ears 4, described limit stiffener 5 can stop two pairs of mounting ears 4 outwards to open because of stressed, be flexibly connected by pin 6 between often pair of mounting ear 4, often pair of mounting ear 4 root is provided with the end stiffener 7 be connected with platform steel plate 2 for strengthening mounting ear 4, the cylinder body 1-1 side of described jack 1 is also provided with carrying handle 8.
Concrete, the top cap 1-2 upper surface of described jack 1 is cambered surface, and in cambered surface, circumferentially direction is provided with U-shaped groove.
