One side of the movable gear row 16 is provided with a static gear row 17, and the movable gear row 16 and the static gear row 17 are arranged in a staggered mode.

The distance from the upper end of the oil cylinder 8 to the lower end of the oil cylinder 8 is a.

The distance between the tooth angle vertex of the movable tooth row 16 and the tooth angle vertex of the fixed tooth row 17 is c.

When the oil cylinder 8 is in a closed state, the distance of the eccentricity of the eccentric wheel 3 is b, and when the oil cylinder 8 is in an open state, the distance of the eccentricity of the eccentric wheel 3 is b2, and the eccentricity b is greater than the eccentricity b 2.

In the using process, when the oil cylinder 8 is in a closed state, that is, the distance a from the upper end to the lower end of the oil cylinder 8 is shortened, at this time, the left side of the second swing arm 10 is pulled downwards, meanwhile, the right side of the second swing arm 10 is lifted upwards and drives the left side of the third swing arm 11 to be lifted upwards, the pulling plate 12 on the right side of the third swing arm 11 is further driven to pull the eccentric wheel 3 upwards in an arc-shaped walking track, so that the eccentric distance of the eccentric wheel 3 is increased, at this time, the eccentric distance of the eccentric wheel 3 is b, so that the eccentric wheel 3 moves according to the elliptical track, and the upper friction wheel 13 is pushed, so that the pushing fixed platform 14 moves upwards and downwards according to the elliptical track, and the further driving movable tooth row 16 moves upwards and downwards according to the elliptical track, that is, the tooth angle of the movable tooth row 16 moves according to the elliptical track, that is, the distance c between the tooth angle vertex of the movable tooth row 16 and the tooth angle vertex of the static tooth row 17 is shortened, at this moment, when the movable rack 16 moves forward and upward, the bar is delivered forward, when the movable rack 16 moves forward and downward, the lowest point of the tooth angle of the movable rack 16 intersects with the waist of the tooth angle of the static rack 17, so that the bar falls at the waist position of the tooth angle of the static rack 17, and then the bar rolls to the corner clamping position of the static rack 17 through self weight, thereby realizing that the bar contacts the static rack in advance to roll, and the points of the driven rack falling on the static rack are always different from each other, thereby effectively avoiding the phenomenon that the black points are generated at the landing position of the bar.

In the process of lifting the fixed platform 14 up and down, the first connecting plate 7 moves along with the fixed platform, so that the connecting rod 6 is pulled to swing left and right, and the first swing arm 5 is further pulled to swing, thereby ensuring the stability of the fixed platform 14 in the process of lifting up and down.

As shown in fig. 2 and 6, when the oil cylinder 8 is in the open state, i.e., the distance a from the upper end to the lower end of the oil cylinder 8 increases, the left side of the second swing arm 10 is pushed upward, meanwhile, the right side of the second swing arm 10 pulls downwards and drives the left side of the third swing arm 11 to pull downwards, and further drives the pulling plate 12 on the right side of the third swing arm 11 to pull the eccentric wheel 3 downwards in an arc-shaped walking track, thereby reducing the eccentric distance of the eccentric wheel 3, at which the eccentric distance of the eccentric wheel 3 is b2, so that the eccentric wheel 3 moves according to a circular track, thereby pushing the upper end friction wheel 13, thereby pushing the fixed platform 14 to move up and down according to the circular track, further driving the movable gear row 16 to move up and down according to the circular track, that is, the tooth angle of the moving tooth row 16 moves along a circular trajectory, that is, the pitch c between the tooth angle vertex of the moving tooth row 16 and the tooth angle vertex of the stationary tooth row 17 increases.
