Preferably, the body 1 is provided with a groove 10 for fixing the terminal 5, so as to realize tight fit between the terminal 5 and the body 1.

Preferably, the second side of the terminal 5 is formed with a limit protrusion 11 cooperating with the second end of the spring plate 4. The elastic sheet 4 and one end matched with the wire can be positioned at the correct position when the wire is not inserted through the limiting protrusion 11, and in addition, the limiting protrusion 11 can also provide a better fixing effect for fixing the wire.

Preferably, the fixing buckle 3 is provided with a guiding oblique block 12 in a protruding manner, and the body 1 is provided with a guiding groove 13 matched with the guiding oblique block 12. Since the guide inclined block 12 is obliquely arranged, the posture of the fixing buckle 3 can be changed through the guide inclined block 12, so that a certain rotation displacement is provided when the locking state and the unlocking state are switched, and one-hand operation is conveniently realized.

Preferably, the operation end of the holder buckle 3 includes a top pushing surface 14 for moving the holder buckle 3 to the locked state, a vertical side pushing surface 15 for moving the holder buckle 3 to the unlocked state, the guide inclined block 12 is separated from the guide groove 13 in the locked state of the holder buckle 3, and the guide inclined block 12 is located in the guide groove 13 in the unlocked state of the holder buckle 3.

Preferably, the elastic sheet 4 is formed with an arc-shaped bending portion 16 matched with the lower end of the fixing buckle 3. The arc-shaped bent portion 16 provides a certain elastic force to enable the fixing buckle 3 to be clamped at the locking step portion 17 in the locked state.

Preferably, a convex hull 8 is formed on the first side of the terminal 5, a clamping hole 9 matched with the convex hull 8 is formed on the first end of the elastic sheet 4, and the first end of the elastic sheet 4 is connected with the terminal 5 through a clamping structure formed by the convex hull 8 and the clamping hole 9.
