The expansion frame includes a transverse telescopic rod 14 arranged on the inner side of the expansion plate 5. The bottom end of the transverse telescopic rod 14 is fixedly connected to the support block 15 on both sides. The top of the transverse telescopic rod 14 is slidably connected to the moving frame 13 on both sides. The inner side of the moving frame 13 is slidably connected to the traction slider 17. The inner side of the pull rod 18 is respectively rotatably connected to the inside of the traction slider 17. The inner sides of the bottom support frame 1 are provided with mounting grooves 20 on both sides. Figure 7 The interior of the mounting slots 20 are all slidably connected to the limiting rods 23, the exterior of the limiting rods 23 are all fixedly connected to the longitudinal telescopic rods 16, the top end of the longitudinal telescopic rods 16 are rotatably connected to the exterior of the support block 15, the fixing plate includes a mounting plate 4 located on the exterior of the expansion plate 5, the interior of the mounting plate 4 is interspersed with fixing bolts 3, and the exterior of the fixing bolts 3 are respectively threadedly connected to the exterior of the support L plate 2;

[0029] When the cam 14 is in the upright position, the cam 14 is moved to the left and right, and the cam 14 is moved to the right and left, so that the cam 14 can slide downwards and slide onto the top of the cam 14.

[0030] Reference Figure 2 、 Figure 5 and Figure 6, a positioning block 22 is inserted into the internal notch of the unfolding plate 5, and the outside of the positioning block 22 is fixedly connected to the toggle handle 6, and the outside of the unfolding plate 5 is fixedly connected to the positioning plate 7, and a spring telescopic rod is installed on the inner side of the positioning plate 7. Positioning holes 21 are provided on both sides of the toggle handle 6 for fixing the toggle handle 6, and positioning rods 10 are slidably connected to the two sides of the positioning plate 7, and the outside of the positioning rod 10 is fixedly connected to the dial block plate 9. The inner side of the dial block plate 9 is slidably connected to the outside of the unfolding plate 5, and one end of the positioning plate 7 is connected to one side of the dial block plate 9 by extrusion springs 11. The outside of the positioning rod 10 is respectively inserted into the inside of the positioning hole 21, and the outside of the positioning rod 10 is fixedly connected to the anti-slip sleeve 8, and the inner side of the anti-slip sleeve 8 is fitted on the other end of the positioning plate 7. One end of the positioning block 22 is fitted on the lower side of the force-bearing slider 19 to fix the force-bearing slider 19;

[0031] When the row fence needs emergency passage, the block plate 9 is pushed downward, thereby pulling the positioning rod 10 downward, and the positioning rod 10 moves downward inside the positioning hole 21, thereby releasing the positioning rod 10 from fixation. At this time, the toggle handle 6 is pushed outward to pull out the positioning block 22. At this time, the force-bearing slider 19 loses its fixation, and the force-bearing slider 19 slides downward. The moving frame 13 and the transverse telescopic rod 14 lose their parallel support fixation and move downward. The longitudinal telescopic rod 16 retracts as the transverse telescopic rod 14 moves downward, and the transverse telescopic rod 14 falls and is supported by the angle of the longitudinal telescopic rod 16, so that people can directly cross over and pass through, thereby improving the flexibility of the row fence and providing effective passage for special events.

[0032] Working principle: After fixing the position where the formwork is placed and installed, the expansion plate 5 is flipped outward by toggling the handle 6, so as to expand the expansion plate 5. As the expansion plate 5 expands, the force-bearing slider 19 generates an outward pulling force on the pull rod 18 and an upward pulling force on the traction slider 17, pulling the moving frame 13 upward. The transverse telescopic rod 14 also moves upward accordingly, thereby generating an upward pulling force on the inner side of the longitudinal telescopic rod 16. After the longitudinal telescopic rod 16 reaches the expansion limit, the bottom limiting rod 23 of the longitudinal telescopic rod 16 slides inward inside the installation chute 20 to expand. And as the expansion plate 5 expands, the traction slider 17 moves to support the outer limit of the moving frame 13, generating an outward pulling force on the moving frame 13, so as to slide on the top of the transverse telescopic rod 14. When the expansion plate 5 is completely vertical and the expansion is completed, the lower side of the expanded expansion plate 5 is placed on the top end of the support L plate 2, and the mounting plate 4 is attached to the outside of the support L plate 2 and is fixed by threading through the fixing bolt 3. When personnel need to pass through the formwork emergently, the toggle plate 9 is toggled downward, thereby pulling the positioning rod 10 downward. The positioning rod 10 moves downward inside the positioning hole 21, so as to release the fixation of the positioning rod 10. At this time, the handle 6 is toggled outward, thereby pulling out the positioning block 22. At this time, the force-bearing slider 19 loses its fixation, and the force-bearing slider 19 slides downward. The moving frame 13 and the transverse telescopic rod 14 lose the fixation of parallel support and move downward. And as the transverse telescopic rod 14 moves downward, the longitudinal telescopic rod 16 retracts. The transverse telescopic rod 14 falls and is supported by the included angle of the longitudinal telescopic rod 16, so that personnel can directly cross and pass through.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
