The upper shed structure with the nip portion of concave structure that the utility model is arranged and hook portion have the under shed structure of hook-shape structure, these two kinds of structures can be good at being interlocked, and card line can be made to settle at one go, easily easily, save the operating time, increase work efficiency.And when implementing, the screw rod of lower positioning end being rotated up and down in the clip of upper stiff end, card line can be completed.
Further, the upper shed that described nip portion comprises left side, right side, underframe and is arranged between left side and right side, described left side and right side shape and structure symmetry, left side and right side are provided with groove all in the horizontal direction, the under shed coupling of described groove and hook-type bar.Setting accurately the carrying out advantageously in card line of this groove.
Further, described hook-type bar comprises hook-type position and shank, and hook-type position is connected with shank, and the left surface of shank is vertical plane.Described nip portion both sides vertically all offer chute, and the left side of chute opening and shank matches.The setting of nip portion both sides chute vertically can move ahead spacing for lower positioning end on a vertical direction, can not deflection, can complete card lineman fast and do.
The under shed of described hook-type bar is provided with nonskid coating.
The upper shed of described nip portion is provided with nonskid coating.Arranging of nonskid coating on the one hand prevents line from occurring possible slippage, can also alleviate upper stiff end and lower positioning end on the other hand to the wearing and tearing of line, play the effect of protective wire.
Lower positioning end also comprises a gag lever post, and described gag lever post passes across screw rod lower end.
To sum up, the beneficial effects of the utility model are:
The snap-in structure that the utility model is arranged can carry out a friendly screens for the external diameter of line to line, and line is fresh less shifting phenomena occurs, and line card can be lived by this set accurately, easily finishes the work, and alleviates handling time, increases work efficiency.
