Description

A two-force rod type combined hook device

Technical field

The invention relates to the technical field of household hook devices, in particular to a two-force rod type combined hook device.

Background technique

Now home decoration is not suitable for hanging items by nailing, and hooks are one of the commonly used utensils for hanging items in the home. But when there is a hook to hang some key items, the hook is easy to fall off from the wall. At present, the patent "a hook with strong load-bearing capacity (CN202579603U)" discloses a hook including three suction cups. Although the load-bearing capacity of the hook is improved, the number of suction cups is simply increased and the cost is high; the patent "vacuum suction cup hook (CN2634175Y) " discloses a kind of vacuum sucker formula hook that has hook support, although can avoid air leakage and better keep the stability of vacuum sucker vacuum state, has improved the load-bearing capacity of hook, but the hook support function is single.
