[0025] Through the coordinated arrangement of the bottom plate 1, bending wheel 2, abutment column 3, mounting tube 4, driving handle 6, connecting plate 5 and limiting plate 7 in the above structure, it is convenient to limit one end of the handlebar body through the coordination of the limiting plate 7 and the bending wheel 2, and then the driving handle 6 is rotated, and the driving handle 6 drives the connecting plate 5 to drive the handlebar body to rotate, and the abutment column 3 can block the handlebar body, so that the handlebar body can be bent around the bending wheel 2.

[0026] Embodiment 2

[0027] Based on the first embodiment, combined with the attached Figure 2 The connecting plate 5 is detachably connected to the bending wheel 2, and a plurality of limit columns 16 are connected to the connecting plate 5. A limit groove cooperating with the limit column 16 is relatively connected to the bottom end of the bending wheel 2. A sliding rod is slidably connected in the mounting tube 4, and a pressure plate 17 is connected to the top of the sliding rod. A spring 18 is connected between the pressure plate 17 and the mounting tube 4. An annular groove 19 is circumferentially connected to the middle part of the sliding rod, and a plurality of through holes 20 are circumferentially connected to the mounting tube 4. Limit beads 22 are arranged in the through holes 20, and a rolling groove 21 is relatively connected to the bending wheel 2.

[0028] The matching arrangement of the bending wheel 2 in the above structure makes it easy to quickly disassemble the bending wheel 2 and replace the bending wheel 2 according to the needs of different bending radii.

[0029] The specific usage is as follows:

[0030] Firstly, the positioning of the bending wheel 2 is facilitated by the coordinated arrangement of the limiting column 16 and the limiting groove. The slide bar moves upward under the elastic force of the spring 18, so that the annular groove 19 and the through hole 20 are not opposite to each other, and the limiting bead 22 is abutted by the outer wall of the slide bar and passes through the through hole 20 and cooperates with the rolling groove 21 to limit the bending wheel 2.

[0031] Then, the threaded rod 9 is driven by the turning handle to drive the limit plate 7 to slide along the slide groove 11, and the limit plate 7 cooperates with the bending wheel 2 to limit one end of the handlebar body; and the other side of the handlebar body abuts against the abutment column 3;

[0032] Next, the connecting plate 5 is driven by the driving handle 6 to drive the bending wheel 2 to rotate. The connecting plate 5 can stably rotate with the mounting tube 4 as the axis through the matching arrangement of the sliding column 13, the arc groove 14 and the ball 15. The handlebar body rotates around the bending wheel 2 under the obstruction of the abutment column 3 to bend. The arrangement of the heater 8 is convenient for heating the handlebar body, enhancing the plasticity and ductility of the handlebar, and can improve the deformation capacity of the steel plate, making the bending smoother. At the same time, it can reduce the probability of cracks in the bending process, and improve the bending quality and durability.

[0033] When the bending radius needs to be changed, the bending wheel 2 can be replaced by pressing the pressure plate 17, which drives the slide rod downward so that the annular groove 19 cooperates with the limiting bead 22. At this time, the bending wheel 2 can be quickly disassembled, making it convenient to disassemble the bending wheels 2 with different wheel diameters.
