[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model provides a portable right-angle bending device for earthing flat steel. Through its structural design, before bending the earthing flat steel, the interval between the axial tangents of the first bending disc and the second bending disc is adjusted according to the specification of the earthing flat steel to be bent. First, press the pressing rod. The pressing rod is pressed towards the adjusting block to drive the ratchet teeth to separate from the ratchet wheel. At this time, the screwing shaft can be rotated to drive the ratchet wheel to rotate in the reverse direction. At the same time, the rotation of the screwing shaft drives the gear to rotate, the rotation of the gear drives the rack to move, and the movement of the rack drives the clamping block to slide towards the inside of the adjusting block and be pulled out from the base. At this time, release the pressing rod, and the spring drives the pressing rod to reset to make the ratchet teeth and the ratchet wheel bite again, thereby changing the position of the adjusting block on the base.

After the interval between the axial tangents is adjusted, rotate the screwing shaft forward. The rotation of the screwing shaft drives the ratchet wheel and the gear to rotate forward. The ratchet teeth engaged with the ratchet wheel prevent the ratchet wheel from reversing, so that the screwing shaft cannot reverse. The forward rotation of the gear drives the rack to move, and the movement of the rack drives the clamping block to slide towards the base until the end of the clamping block is inserted into the base, and then the bending of the earthing flat steel can be started. During bending, pass the earthing flat steel through the midlines of the two bending discs. One end of the earthing flat steel is clamped in the first bending disc, and the other end of the earthing flat steel is clamped in the second bending disc and abuts against the stop block. Then rotate the handle. The rotation of the handle drives the second bending disc to rotate. The rotation of the second bending disc drives the rotating shaft to rotate on the base. While the handle is rotating, the stop block at the end of the handle clamps the earthing flat steel to cause its shape to change. When the earthing flat steel is bent into a right angle, take out the bent earthing flat steel and paint it, and then it can be installed.

[0030] In this embodiment: The utility model is transported to the construction site that is currently under construction. Before bending the grounding flat steel, the interval between the axial tangents of the two bending discs 3 is adjusted according to the specification of the grounding flat steel to be bent. The grounding flat steel can pass through the gap between the upper flange 301 and the lower flange 303 through the interval between the axial tangents of the central axes 302 of the two bending discs 3 that conform to the specification of the grounding flat steel, so that the upper flange 301 and the lower flange 303 clamp the grounding flat steel in the middle. When adjusting the interval, first press the pressing rod 7. Pressing the pressing rod 7 towards the adjusting block 4 drives the ratchet tooth 9 to separate from the ratchet wheel 6. At this time, the screwing shaft 5 can be rotated to drive the ratchet wheel 6 to rotate in the reverse direction. At the same time, the rotation of the screwing shaft 5 drives the gear 10 to rotate. The rotation of the gear 10 drives the rack 11 to move. The movement of the rack 11 drives the clamping block 12 to slide into the adjusting block 4 and be pulled out from the base 1. Through the cooperation of the guiding groove 18 in the adjusting block 4 and the guiding block 19 on the clamping block 12, the clamping block 12 can slide more stably in the adjusting block 4 along the guiding groove 18. At this time, release the pressing rod 7, and the spring 8 drives the pressing rod 7 to reset to make the ratchet tooth 9 engage with the ratchet wheel 6 again, thus changing the position of the adjusting block 4 on the base 1. The change in the position of the adjusting block 4 drives the change in the position of the rotating shaft 13. The change in the position of the rotating shaft 13 drives the change in the position of the bending disc 3 on the rotating shaft 13, so that the interval between the axial tangents of the two bending discs 3 conforms to the specification of the grounding flat steel to be bent. Through the scale 16 located on the base 1, it is convenient for the construction personnel to judge the specification of the grounding flat steel corresponding to the interval between the axial tangents of the current two bending discs 3. After the interval between the axial tangents is adjusted, rotate the screwing shaft 5 forward. The rotation of the screwing shaft 5 drives the ratchet wheel 6 and the gear 10 to rotate forward. The ratchet tooth 9 engaged with the ratchet wheel 6 prevents the ratchet wheel 6 from reversing, so that the screwing shaft 5 cannot reverse. The forward rotation of the gear 10 drives the rack 11 to move. The movement of the rack 11 drives the clamping block 12 to slide towards the base 1 until the end of the clamping block 12 is inserted into the base 1, and then the bending of the grounding flat steel can be started. When bending, the construction personnel pass the grounding flat steel through the midlines of the two bending discs 3. One end of the grounding flat steel is clamped in the gap between the upper flange 301 and the lower flange 303 of the first bending disc 3a, and the other end of the grounding flat steel is clamped in the gap between the upper flange 301 and the lower flange 303 of the second bending disc 3b and abuts against the stop block 15 and is stably clamped. Then rotate the handle 14. The rotation of the handle 14 drives the second bending disc 3b to rotate. The rotation of the second bending disc 3b drives the rotating shaft 13 to rotate on the base 1. While the handle 14 is rotating, the stop block 15 at the end of the handle 14 causes the shape of the grounding flat steel to change. Through the limiting rod 17 located on the first bending disc 3a, when the handle 14 rotates to contact the limiting rod 17, the grounding flat steel is just bent into a right angle, which improves the work efficiency of the construction personnel. After the grounding flat steel is bent into a right angle, take out the bent grounding flat steel and paint it, and then it can be installed.
