One end of the second positioning rod 22 is connected with one third positioning rod 23, and the other end is connected with the other third positioning rod 23.

[0033] As shown, Figure 7 In this embodiment, the first positioning rod 21 and the third positioning rod 23 are connected through a rotating buckle 30, and the second positioning rod 22 and the third positioning rod 23 are connected through the rotating buckle 30; the rotating buckle 30 comprises two buckle rings 31 connected through an axis 32 between the two buckle rings 31, and one of the two buckle rings 31 can rotate relative to the other buckle ring 31, and the maximum angle of rotation is 360°.

[0034] Through the rotation of one of the buckle rings 31, the axial directions of the two buckle rings 31 can be perpendicular to each other, so that the two buckle rings can be connected to two perpendicular positioning rods respectively, thereby realizing the connection of the two positioning rods.

[0035] The buckle ring 31 comprises two rotatably connected buckle parts 311, and the rotatable connection mode of the two buckle parts 311 is a common mode in the technical field, which is not limited here. The cross-sectional shape of the two buckle parts 311 is semicircular, and the two buckle parts 311 can be buckled to form a hollow cylindrical buckle ring, and the two buckle parts 311 are connected through a bolt 312. In use, one of the buckle parts 311 is rotated to open, the opened buckle ring 31 is buckled to the positioning rod, and then the buckle part 311 is rotated to close the buckle ring 31, and the two buckle parts 311 are locked through the bolt 312, so that the buckle ring 31 can be buckled and connected to the positioning rod.

[0036] When the first positioning rod 21 needs to be rotated, the buckle ring 31 connected to one end of the first positioning rod 21 can be opened, so that the one end of the first positioning rod 21 is separated from the buckle ring 31. The other end of the first positioning rod 21 is also connected with the buckle ring 31, and the buckle ring 31 is rotatable, so that the rotation of the first positioning rod 21 can be realized, and the first positioning rod 21 can rotate around the rotation shaft 32 of the rotating buckle 30 connected to the other end of the first positioning rod 21.

According to the width M of the flange plate 101, the spacing between the first positioning rod 21 and the second positioning rod 22 is adjusted to be 1-10mm more than the width M of the flange plate 101, so that the first positioning rod 21 and the second positioning rod 22 can limit the two sides of the flange plate 101 respectively. According to the sum N of the thickness of the two flange plates 101 and the width of the web plate 102, the spacing between the second positioning module 25 and the third positioning module 26 is adjusted to be 1-10mm more than N, so that the second positioning module 25 and the third positioning module 26 can limit the outer side of the two flange plates 101 respectively. Then the position of the first positioning module 24 is adjusted, so that the straight line formed by the first positioning module 24 and the second positioning module 25 is perpendicular to the first positioning rod 21, and the first positioning module 24 and the second positioning module 25 limit the outer side of the same flange plate 101.

[0043] By moving the positioning frame to above the target position, the type steel 100 is positioned in the positioning frame, so that the type steel 100 can be positioned above the target position, so that the type steel 100 can be aligned with the target position and accurately placed in the target position without deviation, thereby improving the accuracy of the type steel 100 in the placement positioning; so that the type steel 100 can be accurately placed in the target position, effectively avoiding that the type steel 100 deviates from the target position.

The connecting rod 41 is perpendicular to the plurality of third positioning rods 23, and the third positioning rods 23 are connected through the connecting rings 42 on the connecting rod 41, so that the plurality of positioning frames can be connected together.

[0049] The bottom of the connecting rod 41 is provided with a directional pulley 43, and the directional pulley 43 can slide along the sliding groove 10. Through the sliding of the directional pulley 43, the plurality of positioning frames can be simultaneously driven to slide along the sliding groove, so that the position of the positioning frame can be adjusted.

[0050] The bottom of the connecting rod 41 is provided with a brake switch 44, and the brake switch 44 controls the rotation of the directional pulley 43.
