Welding anti-slip device based on large-diameter PE pipe

The utility model discloses a welding anti-slip device based on a large-caliber PE pipe, which comprises an L-shaped connecting sleeve, a first PE pipe and a second PE pipe, the first PE pipe is connected to one side of the L-shaped connecting sleeve, the second PE pipe is connected to the bottom of the L-shaped connecting sleeve, the first PE pipe and the second PE pipe are both provided with anti-slip assemblies, and the anti-slip assemblies are connected with the L-shaped connecting sleeve. The two anti-disengaging assemblies are connected through two connecting assemblies. According to the anti-slip device, due to the arrangement of the two anti-slip assemblies, a PE pipe needing to be welded during machining can be clamped, the two anti-slip assemblies are connected through the two connecting assemblies, the stability of the two anti-slip assemblies is ensured, the welding stability is indirectly improved, the reusable anti-slip device is manufactured through the design, the working efficiency is effecti
