The bottom plate 23 has a plurality of limiting holes 231 spaced along the first direction X. In this embodiment, the first direction X and the second direction Y are perpendicular to each other, and the limiting holes 231 are in two rows.

The clamping unit 3 includes a fixed clamping mechanism 31 detachably disposed on the first base body 21, and a movable clamp that is movably disposed on the guiding rod 24 in cooperation with the fixed clamping mechanism 31. Holding mechanism 32, a carding machine capable of moving in the second direction Y to lock the movable clamping mechanism 32 The elastic member 34 is detachably connected to the movable clamping mechanism 32 and the second base 22, and the two are respectively detachably disposed in the corresponding limiting holes 231 to limit the movable clamping mechanism. The limit mechanism 35 of 32.

The movable clamping mechanism 32 has a movably disposed The clamping seat 321 on the guiding rod 24 and a clamping member 325 detachably corresponding to the fixing clamping mechanism 31 are disposed on the clamping seat 321 . The clamping seat 321 has two locking holes 322 that cooperate with the locking mechanism 33. Each of the locking holes 322 has a locking section 323 extending along the second direction Y, and a first direction X extends and communicates the stretch section 324 of the carding section 323.

In this embodiment, the elastic member 34 is detachable at both ends. The retaining seat 321 is connected to the tension spring of the second base 22, and the limiting mechanism 35 is a substantially convex type limiting block. In practical applications, there may be only one limiting mechanism. 35 can also achieve the same effect, and is not limited by the disclosure of this embodiment.

The clamping mechanism 33 has a movable position along the second direction Y The push rod 331 and the two push rods 331 are connected to the clip 332 which is engaged in the locking hole 322.
