Preferably, a guide hole 21 is arranged below the support seat 2; the elastic means 3 comprise: the guide rod 31 is arranged in the guide hole 21, the upper part of the guide rod 31 is not contacted with the bottom of the guide hole 21, and the needle pressing device 4 is welded and fixed below the guide rod 31; a spring 32 mounted on the guide rod 31, wherein the outer diameter of the spring 32 is larger than the aperture of the guide hole 21, the length of the spring 32 is equal to the length of the guide rod 31 exposed out of the guide hole 21, or the length of the spring 32 is slightly larger than the length of the guide rod 31 exposed out of the guide hole 21, so that the needle pressing device 4 is slightly pressed downwards; the needle pressing device 4 is located above the upper knitting needle 121, when the upper knitting needle 121 is flat, the pressure of the upper knitting needle 121 is small, the operation of the upper knitting needle 121 is not affected, when the front end of the upper knitting needle 121 is pried upwards, the needle pressing device 4 is jacked up to drive the guide rod 31 to move upwards, meanwhile, the spring 32 is compressed, the spring 32 is deformed, then, the needle pressing device 4 is forced downwards, the needle pressing device 4 is returned, and the upper knitting needle returns to the horizontal operation position.
Preferably, as shown in fig. 1 and 3, a plurality of the guide holes 21 are symmetrically arranged below the support seat 2; the elastic devices 3 are arranged in the plurality of guide holes; so that the pressure generated by the needle pressing device 4 is more balanced when the needle is floated.
Preferably, as shown in fig. 2 and 4, the needle pressing device 4 is a fan-shaped piece, and rounded corners are arranged on two sides in the width direction, so that the problem of collision between the upper knitting needle and the needle pressing device 4 during operation is avoided.
Preferably, as shown in fig. 2 and 4, the needle pressing device 4 is a fan-shaped piece, and both sides in the width direction are provided with round corners, and both sides in the length direction are provided with round corners (not shown in the figure); when the upper dial rotates and passes through the gap between two adjacent needle pressing devices 4, if the upper dial is in plane butt joint, the upper knitting needle has a certain probability of being clamped into the gap during rotation, and the risk of breaking the upper knitting needle exists; and both sides of both ends in the length direction are provided with round corners, the gap obviously moves upwards, and the upper dial can not be clamped into the gap at the height during the rotary motion, so that the problem of breaking the upper knitting needle during the operation is solved.
