[0048] The arc scale 7 has one end connected to the first driven rod 6 through the connecting block 94 (the scale value at the connection between the first driven rod 6 and the arc scale 7 is 0), and the other end is a movable end and can move along the circumferential direction of the vertical plate 2.

[0050] The working principle of the above bending equipment that is easy to observe the bending angle is:

[0051] See also Figure 1 and Figure 2 First, draw a line at the copper bar to be bent to mark the position, then pull open the side push plate, place the copper bar flat on the two sets of rollers 3 and align the drawn line with the bending pressure head 4, and then move the bending pressure head 4 through the driving device, so that the bending pressure head 4 acts on the copper bar to bend the copper bar.

One end of the second driven rod 8 points to the arc scale 7.
