Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-4 , a safety enclosure, including a protective plate 1, a second connecting plate 7 is fixedly connected to the right side of the protective plate 1, an extension plate 5 is arranged inside the second connecting plate 7, the extension plate 5 inside the extension plate 5, a first connecting plate 2 is fixedly connected to the left side of the extension plate 5, and convenient splicing and limiting structures are respectively arranged at the bottom end of the extension plate 5 and both sides of the protective plate 1;

[0024] The splicing limit structure includes a fixing plate 3, an extension plate 5, a limit chute 15 and a limit slider 17. The bottom end of the extension plate 5 is fixedly connected with the limit slider 17. The limit chute 15 is arranged at the bottom end inside the protection plate 1. The left side of the first connecting plate 2 is fixedly connected with the fixing plate 3. Slots 4 are respectively formed at the bottom end and the top end inside the fixing plate 3. Grooves 8 are formed on the right side inside the second connecting plate 7. Limit clamping blocks 22 are respectively fixedly connected to the bottom end and the top end inside the second connecting plate 7. The bottom ends of the first connecting plate 2 and the second connecting plate 7 are respectively fixedly connected with a base 13. A fixing rod 14 is arranged inside the base 13;

[0025] The limit slider 17 is arranged inside the limit chute 15. The limit slider 17 slides left and right inside the limit chute 15. The extension plate 5 slides inside the protection plate 1. The fixing plate 3 is embedded inside the groove 8. The limit clamping block 22 is embedded inside the slot 4;

[0026] Specifically, as Figure 1 and Figure 4 shown, when in use, pull the first connecting plate 2. The first connecting plate 2 drives the extension plate 5 to move inside the protection plate 1, so that one side of the extension plate 5 slides out from inside the protection plate 1, thereby the overall length of the safety enclosure can be adjusted. After adjustment, insert the fixing rod 14 into the base 13 and the soil to fix the enclosure. When two groups of safety enclosures need to be spliced, insert the fixing plate 3 into the groove 8, thereby the two groups of safety enclosures can be spliced together. When the enclosure needs to be transported, push the extension plate 5 into the protection plate 1 to reduce the occupied area of the safety enclosure, thereby facilitating the transportation of the safety enclosure.

[0027] Embodiment 2: Fixing grooves 6 are respectively formed on both sides of the top end inside the extension plate 5. A pulling block 10 is arranged on the left side of the top end of the protection plate 1. The bottom end of the pulling block 10 is fixedly connected with a limit rod 9. A spring 18 is fixedly connected between the pulling block 10 and the protection plate 1. The spring 18 is arranged at the top end outside the limit rod 9. The bottom end of the limit rod 9 is embedded inside the fixing groove 6;

[0028] Specifically, as Figure 1 and Figure 2 shown, when the extension plate 5 needs to be moved, pull the pulling block 10. The pulling block 10 drives the limit rod 9 to rise so that the bottom end of the limit rod 9 disengages from inside the fixing groove 6, thereby the extension plate 5 loses its fixation. After moving the extension plate 5 to the appropriate position, release the pulling block 10. The spring 18 makes the bottom end of the limit rod 9 embedded inside the fixing groove 6 through its own elasticity, thereby fixing the extension plate 5 to prevent the extension plate 5 from accidentally sliding.

[0029] Embodiment 3: Mounting plates 19 are provided at both ends of the protective plate 1. A first mounting block 21 is movably hinged between the mounting plates 19.

The protective sleeve 11 is sleeved outside the threaded rod 12 through the threaded groove 20, and the threaded rod 12 and the threaded groove 20 cooperate with each other;

[0030] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, after fixing the protective plate 1 and the extension plate 5, rotate the threaded rod 12. The threaded rod 12 rotates inside the threaded groove 20, so that the threaded rod 12 can drive the bottom plate 16 to lift and adjust the height of the bottom plate 16. After adjustment, rotate the protective sleeve 11 so that the bottom end of the bottom plate 16 contacts the ground, thereby supporting both ends of the protective plate 1 and preventing the protective plate 1 from tilting during use.

[0031] Working principle: When the utility model is in use, place the fence in a suitable position, then pull the pull block 10. The pull block 10 drives the limit rod 9 to rise, so that the bottom end of the limit rod 9 disengages from the inside of the fixing groove 6, thereby enabling the extension plate 5 to lose its fixation. After the extension plate 5 loses its fixation, pull the first connecting plate 2. The first connecting plate 2 drives the extension plate 5 to move inside the protective plate 1, so that one side of the extension plate 5 slides out of the inside of the protective plate 1, thereby adjusting the overall length of the safety enclosure. After adjustment, move the extension plate 5 to a suitable position and then release the pull block 10. The spring 18 makes the bottom end of the limit rod 9 fit into the inside of the fixing groove 6 through its own elasticity, thereby fixing the extension plate 5 and preventing the extension plate 5 from accidentally sliding. After adjustment, insert the fixing rod 14 into the inside of the base 13 and the soil to fix the enclosure. When it is necessary to join two groups of safety enclosures, insert the fixing plate 3 into the groove 8, thereby enabling the two groups of safety enclosures to be joined together. When it is necessary to transport the enclosure, push the extension plate 5 into the inside of the protective plate 1 to reduce the occupied area of the safety enclosure, thereby facilitating the transportation of the safety enclosure. After fixing the protective plate 1 and the extension plate 5, rotate the threaded rod 12. The threaded rod 12 rotates inside the threaded groove 20, so that the threaded rod 12 can drive the bottom plate 16 to lift and adjust the height of the bottom plate 16. After adjustment, rotate the protective sleeve 11 so that the bottom end of the bottom plate 16 contacts the ground, thereby supporting both ends of the protective plate 1 and preventing the protective plate 1 from tilting during use.
