[0028] The base 1 includes a limiting protrusion 11 and a support block 12, the limiting protrusion 11 is fixedly connected to one end of the upper part of the base 1, the four corners of the lower part of the base 1 are respectively fixedly connected to the support block 12, a first through hole 13 is formed through the center of the base 1, the first through hole 13 is fixedly connected to the positioning column 2, and second through holes 14 are formed through the support block 12 at the four corners of the base 1, and a plurality of limiting threaded holes 15 are formed through the base 1, and the plurality of limiting threaded holes 15 are evenly spaced along an arc with the center of the first through hole 13 as the center of the circle, and the angle limiter 7 is installed on one of the limiting threaded holes 15. Preferably, the angle limiter 7 is threadedly connected with the limiting threaded hole 15, and the limiting threaded hole 15 is arranged at one end of the bottom plate away from the limiting protrusion 11 and close to the edge of the circular chassis 3. The base 1 enables the lightning strip bending tool to be well fixed and not move. When the angle limiter 7 is located in different limiting threaded holes 15, the round steel 8 is pushed into the V-groove 42 of the positioning wheel 4 by adjusting the limiting component 5. At the same time, the limiting component 5 limits one end of the round steel 8, and then the round steel 8 is bent. The other end of the round steel 8 is bent to the angle limiter 7. Different angles can be bent, and they are obtuse angles, which can be used for the production of lightning strips of different types.

[0029] The thickness of the limiting protrusion 11 is the same as that of the circular chassis 3. One end of the limiting protrusion 11 is a square end, and the other end is an arc-shaped end. A gap is left between the arc-shaped end of the limiting protrusion 11 and the edge of the circular chassis 3, so that the circular chassis 3 is not affected by the arc-shaped end of the limiting protrusion 11 when rotating. A first limiting hole 111 is provided through the limiting protrusion 11 near the arc-shaped end. The first limiting hole 111 is fixedly connected to the limiting component 5. The setting of the limiting protrusion 11 is used to lift the limiting component 5 so that the limiting component 5 extends above the circular chassis 3 to limit the round steel 8; the upper part of the limiting protrusion 11 is fixedly connected to the limiting component 5, and one end of the limiting component 5 extends to the upper part of the circular chassis 3. A gap is left between the lower part of the limiting component 5 and the upper part of the circular chassis 3, so that the limiting component 5 does not affect the rotation of the circular chassis 3.

[0030] A first positioning hole 31 is formed through the center of the circular chassis 3 , and the first positioning hole 31 is rotatably connected to the positioning column 2 . A second limiting hole 32 is formed through the circular chassis 3 near the edge, and the second limiting hole 32 is fixedly connected to the bending component 6 .

[0031] The center of the positioning wheel 4 is penetrated by a second positioning hole 41 corresponding to the positioning column 2, and a V-shaped groove 42 is provided on the outer side of the positioning wheel 4. When the round steel 8 is bent, the V-shaped groove 42 of the positioning wheel 4 plays a role of limiting and guiding.

[0032] The limiting assembly 5 includes a first outer frame 51, a first inner frame 52, a first adjusting bolt 53, a first baffle 54, a first limiting bolt 55, a first limiting nut 56 and a first gasket 57. The first outer frame 51 and the first inner frame 52 are both U-shaped. The first outer frame 51 is fixedly connected to the limiting protrusion 11. The first inner frame 52 is arranged in the first outer frame 51 and is slidably connected to the first outer frame 51. The first baffle 54 is fixedly arranged at the U-shaped opening of the first inner frame 52. The first limiting bolt 55 passes through the first inner frame 52 and is fixed in the first limiting hole 111. The first limiting bolt 55 is sleeved with a first gasket 57 on the upper part and is locked by the first limiting nut 56. The first gasket 57 is square, and the lower surface of the first gasket 57 is simultaneously fixed to the first outer frame 51. The first inner frame 52 is abutted against the upper part of the first inner frame 52, and the first inner frame 52 can be pressed. After the first inner frame 52 is slidably adjusted to the position, the first limiting nut 56 and the first gasket 57 can limit the first inner frame 52. The first outer frame 51 is centrally penetrated by a first threaded hole 511 at one end away from the U-shaped opening. The first threaded hole 511 is threadedly connected with the first adjusting bolt 53. After the first inner frame 52 is slidably adjusted to the position, the first adjusting bolt 53 is tightened to make the first adjusting bolt 53 abut against the first inner frame 52. By sliding the first inner frame 52, the first baffle plate 54 is driven to move. At the same time, the first baffle plate 54 drives the round steel 8 to move into the V-groove 42 of the positioning wheel 4, and the first adjusting bolt 53 and the first limiting nut 56 are tightened to make the first baffle plate 54 limit the round steel 8.

[0033] The bending assembly 6 includes a second outer frame 61, a second inner frame 62, a second adjusting bolt 63, a handle 64, a second baffle 65, a second limiting bolt 66, a second limiting nut 67 and a second gasket 68. The second outer frame 61 and the second inner frame 62 are both U-shaped. The second outer frame 61 is fixedly connected to the circular chassis 3. The second inner frame 62 is arranged in the second outer frame 61 and is slidably connected to the second outer frame 61. The second baffle 65 is fixedly arranged at the U-shaped opening of the second inner frame 62. The second limiting bolt 66 passes through the interior of the second inner frame 62 and is fixed in the second limiting hole 32. The upper part of the second limiting bolt 66 is sleeved with a second gasket 68 and is locked by the second limiting nut 67. The second gasket 68 is square. The lower surface of the second gasket 68 abuts against the upper parts of the second outer frame 61 and the second inner frame 62 at the same time, so as to press the second inner frame 62. After the second inner frame 62 is slidably adjusted to the position, the second limiting nut 67 and the second gasket are fixedly arranged. 68 can limit the second inner frame 62, and a second threaded hole 611 is centrally provided at one end of the second outer frame 61 away from the U-shaped opening, and the second threaded hole 611 is threadedly connected with the second adjusting bolt 63. After the second inner frame 62 is slid to adjust the position, the second adjusting bolt 63 is tightened so that the second adjusting bolt 63 abuts against the second inner frame 62, and the handle 64 is fixedly connected to one side of the second outer frame 61, and a fourth through hole 612 is centrally provided at one side of the second outer frame 61, and the fourth through hole 612 is fixedly connected to the handle 64. The bending component 6 is rotated by the handle 64, and the bending component 6 drives the circular chassis 3 to rotate. The bending component 6 pushes the round steel 8 to rotate in an arc with the positioning column 2 as the axis through the second baffle plate 65 until the rotation stops at the angle limiter 7, so that the round steel 8 can be bent to a fixed angle. At the same time, the second baffle plate 65 can increase the contact area between the bending component 6 and the round steel 8 to avoid damage to the round steel 8 when bending the round steel 8.

[0034] The working principle of a lightning protection strip bending tool is as follows: a round steel bar 8 is placed on the upper part of a circular chassis 3, and a handle 64 is turned to make the bending assembly 6 close to the limiting assembly 5. By adjusting the limiting assembly 5 and the bending assembly 6, the first baffle plate 54 and the second baffle plate 65 are made flush, and the round steel bar 8 is jointly pushed into the V-shaped groove 42. At the same time, the first baffle plate 54 limits one end of the round steel bar 8. Subsequently, the bending assembly 6 is rotated by the handle 64. The bending assembly 6 drives the circular chassis 3 to rotate in an arc with the positioning column 2 as the axis. When the circular chassis 3 rotates, one end of the round steel bar 8 is limited by the first baffle plate 54 and cannot rotate, while the other end of the round steel bar 8 rotates in an arc around the positioning column 2 under the push of the second baffle plate 65. The round steel bar 8 rotates to the angle limiter 7. Under the limiting action of the angle limiter 7, the round steel bar 8 is bent to the set angle.

[0035] The round steel 8 can be galvanized round steel, which can better achieve the lightning protection effect.

[0036] The utility model provides a lightning strip bending tool. By adjusting the first baffle 54 of the limiting component 5 and the second baffle 65 of the bending component 6, the lightning strip bending tool can be suitable for round steels 8 of different models. By rotating the bending component 6, the round steel 8 is pushed to rotate to the angle limiter 7 with the positioning column 2 as the center axis, and the round steel 8 is bent out at a set angle at one time. The angle limiter 7 can be selectively set in a certain limiting threaded hole 15, which is suitable for the production of lightning strips with different bending angles.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
