[0038] like Figures 1-6 As shown, a telescopic mechanism of a warning fence comprises: a fixed rod 1 for being set on the ground; a plurality of positioning rods 2, the positioning rods 2 and the fixed rod 1 being arranged at intervals; a warning fence 3, which is made of flexible material, one end of which is wound around the fixed rod 1 and the other end of which extends outward from the fixed rod 1; a plurality of positioning sleeves 4, each of which is provided with two positioning sleeves 4 opposite to each other up and down on each positioning rod 2, the positioning sleeve 4 having two locking grooves 401, the locking groove 401 having an entrance 4011, the entrances 4011 of the locking grooves 401 on the upper and lower sides being opposite to each other up and down, and the upper and lower side edges of the warning fence 3 are respectively inserted into the locking grooves 401 from the entrances 4011 on the upper and lower sides; a plurality of pressing plates 5, each of which is movably provided with a pressing plate 5, which abuts against one side of the warning fence 3 after moving, and is used for fixing the part of the warning fence 3 extending outward on the positioning sleeve 4.

[0039] When in use, the fixing rod 1 is fixed on the ground, one end of the warning fence 3 is pulled out from the fixing rod 1 to a suitable length, the number of positioning rods 2 and the fixed position of the positioning rods 2 on the ground are selected according to the terrain and fixing requirements, and then the extended warning fence 3 is fixed using the positioning sleeve 4.

[0040] Taking linear warning as an example, the warning fence 3 extends to the right, the positioning rods 2 are arranged at intervals between them and between the positioning rod 2 and the fixed rod 1. Both the front and rear sides of each positioning sleeve 4 have locking grooves 401. When conducting linear warning, the warning fence 3 passes through the locking groove 401 at the rear side, and then the pressing plate 5 is used to press against the warning fence 3 to fixedly connect the warning fence 3 and the positioning sleeve 4. On one positioning rod 2, two positioning sleeves 4 are symmetrically arranged up and down, and the entrances 4011 on the upper and lower sides are also symmetrically arranged up and down. The entrance 4011 of the upper positioning sleeve 4 faces downward, and the entrance 4011 of the lower positioning sleeve 4 faces upward, so that the upper side edge of the warning fence 3 enters the upper locking groove 401 from the downward entrance 4011, and the lower side edge of the warning fence 3 enters the lower locking groove 401 from the upward entrance 4011. The locking groove 401 runs through the positioning sleeve 4 from left to right.

[0041] As Figure 6 shown, when it is necessary to set a restricted space for entering the warning area, after the fixed rod 1 and the positioning rod 2 are both set up, it can be set between the two positioning rods 2. When the warning fence 3 passes by the left positioning rod 2, it first passes through the locking groove 401 at the rear side for fixation, and then enters the locking groove 401 at the front side for fixation. And the warning fence 3 between the front and rear locking grooves 401 is in a slack state, not a taut state, with a redundancy. Then the warning fence 3 extends to the right positioning rod 2 for fixation, and is fixed in one of the locking grooves 401 on the right positioning rod 2. And the warning fence 3 between the two positioning rods 2 is in a taut state for use as a restriction of the area during normal warning. When it is necessary to enter the warning area with restrictions, the locking groove 401 at the rear side of the left positioning rod 2 is loosened, and the fixation of the pressing plate 5 is removed, then the redundant warning fence 3 between the front and rear locking grooves 401 of the left positioning rod 2 is released, and a restricted space concave into the warning area can be formed. Similarly, this usage method can be used for opening a door. By releasing a sufficient amount of the warning fence 3 made of a flexible material, the warning fence 3 between the two positioning rods 2 can be lifted upward or lowered to the ground to open the area between the two positioning rods 2 for convenient free entry and exit, etc.

[0042] The warning fence 3 is made of a flexible material, such as cloth, plastic, etc. The upper and lower sides of the warning fence 3 are used for fixation with the locking groove 401, and the middle part can be provided with a hollow.

[0043] Furthermore, it further includes: locking bolts 501, there are several of them, each locking groove 401 is correspondingly provided with a locking bolt 501.
