[0008] The raised arrangement forms a lever that saves effort, allowing the clip to be opened with less force.

[0009] On the other hand, the utility model provides a clip with a sheath, comprising a clip and at least one of the above-mentioned sheath bodies, wherein the sheath body is inserted into the handle of the clip through a groove.

[0010] The clip comprises:

[0011] The elastic body is provided with at least one first bending portion, and the elastic body at two ends of the at least one first bending portion forms opposite clamping portions;

[0012] At least two handles are arranged opposite to each other, the first end of the handle is connected to the elastic body, and the second end is sleeved with a sheath body. The two sheath bodies move toward each other to deform the elastic body and increase the distance between the two clamping parts.

[0013] The protrusion is arranged at a position close to the first curved portion. A rotating groove is arranged on the elastic body, and a rotating shaft matching the rotating groove is arranged at the first end of the handle. At least one second curved portion is arranged on the handle, and the handle at both ends of at least one second curved portion forms an elastic arm, and the rotating shaft is arranged at the end of the elastic arm.

[0014] The two elastic arms abut against the inner wall of the groove to achieve position limiting.

[0015] Through the above technical solution, the provision of the elastic arm can achieve stable installation of the sheath body.

[0016] Compared with the prior art, the advantages of the present invention are: the present invention has a simple structure, increases the contact area between the clip and the user's hand, reduces the contact surface pressure, and the raised setting on the sheath makes the clip more labor-saving when used, thereby improving the user experience.
