[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Please see attached Figure 1-4 A new type of metal-clad hose socket connection device in an embodiment of the utility model includes a hose 1 and a hose 2 3, wherein the hose 1 is connected to the outside of the hose 2 3, and a connecting mechanism 2 is connected between the hose 1 and the hose 2 3;
[0029] The connecting mechanism 2 includes a connecting sleeve 1 23 and a connecting sleeve 2 28. The connecting sleeve 1 23 and the connecting sleeve 2 28 are mutually limited.

When the internal thread of the fastening sleeve 21 is fully engaged with the external thread of the connecting sleeve 23, the arc ring 212 can be connected to the multiple arc grooves 221, thereby laterally limiting the fastening sleeve 21 and the arc grooves 221, effectively preventing the fastening sleeve 21 from separating from the arc grooves 221.
[0034] The outer side of the hose 1 is provided with a plurality of grooves 4 spaced equidistantly, and the plurality of grooves 4 cooperate with and connect with the plurality of arc-shaped clamping plates 22 and limit them, so that when the plurality of arc-shaped clamping plates 22 are connected to the hose 1, axial displacement of the plurality of arc-shaped clamping plates 22 is effectively avoided.
