[0032] Reference Figure 2-Figure 3 The inner wall of the fixing frame 1 is detachably mounted with a shielding assembly 5, and the inner wall of the bottom end of the fixing frame 1 is provided with a supporting assembly 6. The shielding assembly 5 includes a connecting rod 51, and an empty groove is opened on the inner side wall of the fixing frame 1. The connecting rod 51 is plugged into the inner wall of the empty groove of the fixing frame 1. The plugging between the two can position and fix the upper and lower groups of connecting rods 51 after they are unfolded, so as to play a role of enclosure and shielding. The connecting rod 51 is provided with two groups, an upper and a lower groups, and a telescopic rod 52 is hinged between the two groups of connecting rods 51. The telescopic rod 52 is composed of three groups of rod bodies that are mutually sleeved, and the bottom end of the telescopic rod 52 is hinged to the inner wall of the bottom connecting rod 51, and the other end is hinged to the inner wall of the bottom end of the upper group of connecting rods 51. Through the extension and retraction of the telescopic rod 52, the two groups of connecting rods 51 can be brought closer to each other, thereby reducing the occupied space and facilitating carrying.

[0033] Reference Figure 2-Figure 3 The inner wall of the fixing frame 1 is elastically connected with the pull rod 53 through a limit spring 55, one end of the limit spring 55 is fixedly connected to the surface of the bottom end of the pull rod 53, and the other end of the limit spring 55 is fixedly connected to the inner wall of the bottom end of the fixing frame 1. The function of the limit spring 55 is to automatically reset the position of the pull rod 53 after it is pulled outward, so that the round block at its bottom can always be fixed in the position of the insertion of the through hole 54. The pull rod 53 passes through and is slidably connected to the inner wall of the fixing frame 1, and the right side outer wall of the pull rod 53 is inserted into the inner wall of the through hole 54. The insertion between the two can expand the upper two sets of connecting rods 51 and insert them into the position of the inner wall of the empty groove of the fixing frame 1 for fixing, so as to avoid the connecting rod 51 from detaching from the inner wall of the fixing frame 1 during use. Through holes 54 are provided on the surfaces of the two sets of connecting rods 51.

[0034] Reference Figure 1 and Figure 4The support assembly 6 includes a handle 61, which is rotatably connected to the outer wall of the bottom end of the fixed frame 1, and the bevel gear A62 is rotatably connected to the inner wall of the bottom end of the fixed frame 1. The end of the handle 61 is fixedly connected to the bevel gear A62. When the handle 61 rotates, the bevel gear A62 will be driven to rotate synchronously with it, so that the bevel gear A62 engages with the bevel gear B63. The top of the inner side wall of the fixed frame 1 is rotatably connected to the bevel gear B63, and the bottom end of the outer wall of the bevel gear B63 is fixedly connected to a threaded rod 64. When the bevel gear B63 rotates due to the engagement of the bevel gear A62, the threaded rod 64 will be driven to rotate synchronously with it, and the threaded rod 64 can only rotate in situ because the bevel gear B63 rotates on the inner wall of the fixed frame 1.

[0035] Reference Figure 4 The surface of the threaded rod 64 is threadedly connected with a tapered rod 65, and the inner wall of the tapered rod 65 is provided with an internal thread that fits the outer wall of the threaded rod 64, so that the threaded rod 64 will drive the tapered rod 65 to rotate synchronously with it when it rotates, and because the tapered rod 65 can only move up and down on the inner wall of the fixed frame 1, when the threaded rod 64 rotates, it will drive the tapered rod 65 to move up and down on the inner wall of the fixed frame 1, and it itself will not rotate. The bottom end of the bevel gear A62 is meshed with the left side of the bevel gear B63, and the tapered rod 65 penetrates and is slidably connected to the inner wall of the bottom end of the fixed frame 1. The inner wall of the bottom end of the fixed frame 1 is provided with guide blocks that fit on both sides of the tapered rod 65, so that the tapered rod 65 can only move up and down on the inner wall of the fixed frame 1 and cannot be separated from its inner wall.

[0036] Working principle: First, a mounting plate is provided at the bottom of the fixing frame 1, and the whole can be fixed on the flat ground by expansion screws on the flat ground, which plays a supporting role for the whole. The mounting foot 2 on the outer side wall of the fixing frame 1 can be detachably mounted with the warning plate 4 by bolts 3, and the bolts 3 are used to penetrate the inner wall of the mounting foot 2 and are threadedly connected with the inner wall of the warning plate 4 to fix the warning plate 4, thereby playing a warning role at the enclosure.

[0037] The inner side wall of the fixing frame 1 is provided with an empty slot, and the upper and lower connecting rods 51 can be plugged into the empty slot to achieve positioning and fixing of the unfolded state, which plays a role of enclosure and shielding. A telescopic rod 52 is hinged between the two connecting rods 51. The telescopic rod 52 is composed of three groups of rod bodies that are mutually sleeved. Its bottom end is hinged to the inner wall of the bottom connecting rod 51, and the other end is hinged to the inner wall of the bottom end of the upper connecting rod 51. Through the telescopic rod 52, the two connecting rods 51 can be brought closer to each other to reduce the occupied space and facilitate carrying. The inner wall of the fixing frame 1 is elastically connected to the pull rod 53 through a limit spring 55. The limit spring 55 can automatically reset the position of the pull rod 53 after being pulled outward. When the right outer wall of the pull rod 53 is plugged into the through hole 54, the upper two connecting rods 51 can be unfolded and inserted into the position of the inner wall of the empty slot of the fixing frame 1 to be fixed, so as to prevent the connecting rod 51 from being separated from the inner wall of the fixing frame 1 during use.

[0038] When fencing on the construction mud ground, first, the handle 61 is rotated to connect to the outer wall at the bottom end of the fixed frame 1, and its end is fixedly connected to the bevel gear A62. When the handle 61 is rotated, the bevel gear A62 will be driven to rotate synchronously, thereby engaging with the bevel gear B63. The bevel gear B63 is rotatably connected to the top of the inner side wall of the fixed frame 1, and the bottom end of the outer wall of the bevel gear B63 is fixedly connected to the threaded rod 64. When the bevel gear B63 rotates due to the engagement of the bevel gear A62, it will drive the threaded rod 64 to rotate synchronously, because the threaded rod 64 can only rotate in place on the inner wall of the fixed frame 1. The surface of the threaded rod 64 is threadedly connected to the tapered rod 65, and the inner wall of the tapered rod 65 is provided with an internal thread that fits the outer wall of the threaded rod 64, so that when the threaded rod 64 rotates, the tapered rod 65 will be driven to rotate synchronously, and the tapered rod 65 can only move up and down on the inner wall of the fixed frame 1 and will not rotate. When the bevel gear A62 is engaged with the bevel gear B63, the tapered rod 65 will move up and down on the inner wall of the fixed frame 1, thereby entering into the soil on the construction ground, thereby providing stable support for the whole.
