This embodiment provides a double cassette connects first device, it is used for being connected with the body. In this embodiment, the body adopts the hose to with the butt joint of double cassette joint device. Referring to fig. 1, the dual ferrule adapter device includes a second ferrule, a limiting member, a connecting tube 7 centered symmetrically with the second ferrule 5, a plurality of clamping blocks, and a locking ring.

Referring to fig. 2, 3 and 4, the inner surface of the second ferrule 5 is provided with a first internal thread. The limiting piece is arranged in the second cutting sleeve 5, and two ends of the limiting piece are both positioned outside the second cutting sleeve 5; the limiting part is provided with a through hole coaxial with the second clamping sleeve 5. The outer surface of the connecting pipe 7 is provided with an external thread matched with the first internal thread; one end of the connecting pipe 7 is sleeved at one end of the limiting part outside the second clamping sleeve 5. The setting of joint piece 3 is kept away from 5 one end of second cutting ferrule at connecting pipe 7, the inner wall of joint piece 3 with the outer wall of locating part is laminated mutually, and is adjacent leave certain clearance between the joint piece 3 to affiliated joint piece 3 can be out of shape under the exogenic action. When the pipe body to be connected is sleeved outside the clamping block 3, the clamping block 3 can be pressed to deform. The inner wall of the locking ring 1 is provided with a section of second internal thread matched with the external thread. When the locking ring 1 is in threaded connection with the connecting pipe 7, one end of the pipe body to be connected is clamped between the outer wall of the clamping block 3 and the inner wall of the locking ring 1.
