It has the advantages of high protection performance, convenient disassembly and assembly, low implementation cost, and easy promotion and implementation.
[0028] Preferably, the anti-slip layer 300 is made of silica gel, and is provided with anti-slip patterns on a side thereof close to the liquid dispensing tube 2 .
[0029] In the actual implementation process, by providing anti-slip grooves on the side of the anti-slip layer close to the liquid dispensing pipe, when the protective cover is arranged on the liquid dispensing pipe, the friction between the liquid dispensing pipe and the protective cover is increased, thereby improving the installation stability.
