Through above-mentioned technical scheme, after the position of adjusting the gag lever post, make it tightly contradict with the stand through twisting the second positioning bolt for the slider is fixed on the stand, makes the position of gag lever post can fix.

The utility model discloses further set up to: the side wall of the sliding block is provided with a limiting hole which penetrates through the sliding block and is horizontally arranged, the limiting rod is connected in the limiting hole in a sliding mode, the length of the limiting rod is larger than the depth of the limiting hole, and the sliding block is provided with a first positioning bolt which is used for fixing the limiting rod on the sliding block.

Through above-mentioned technical scheme, slide in spacing downthehole through letting the gag lever post for still can make it reach more accurate position through adjusting the gag lever post after the fixing base is fixed.

The utility model discloses further set up to: the stand is the cylinder.

Through the technical scheme, the upright column is arranged to be the cylinder, so that the sliding block can rotate along the axis of the upright column, the limiting rod and the end face of the workpiece can be opposite to the workpiece by rotating the sliding block when the workpiece faces the irregular workpiece of the end face, and the wide applicability of the device is improved.

The utility model discloses further set up to: the second positioning bolts are at least two, and the included angle between every two adjacent second positioning bolts is smaller than 180 degrees.

Through the technical scheme, because two adjacent second positioning bolts are not the same straight line any more, when the second positioning bolts are screwed down, the upright posts can be subjected to the extrusion forces applied to the upright posts by the second positioning bolts in different directions, so that the slide blocks and the upright posts are more firmly fixed.

The utility model discloses further set up to: the fixing base below is provided with the fixed block, be provided with the adjusting bolt who is used for adjusting interval between fixing base and the fixed block on the fixing base.

Through above-mentioned technical scheme, come the interval between control fixing base and the fixed block through rotating adjusting bolt, made things convenient for installation and dismantlement to the device on lathe or other equipment.

The utility model discloses further set up to: one end of the limiting rod is a pointed end.

Through the technical scheme, the one end of the limiting rod is processed into the pointed end, so that the situation that the machining precision of the workpiece is reduced due to the fact that the limiting rod is stressed and deviated because the end face of the limiting rod and the end face of the workpiece cannot be opposite to each other is avoided.

The utility model discloses further set up to: a plurality of standby holes are formed in the sliding block, and each standby hole is located below the positioning hole.

Through above-mentioned technical scheme, because the screw tooth junction atress between second positioning bolt and the location sky is too big, cause smooth silk easily after long-time the use, through setting up the spare hole, the life of this equipment has been prolonged to the change looks.

To sum up, the utility model discloses following beneficial effect has:

1. the degree of freedom of the workpiece is further limited by the interference of the limiting rod and the end face of the workpiece, and the machining precision of the workpiece is improved;

2. because the slider can rotate on the stand, when processing to the anomalous work piece in terminal surface, can make the gag lever post adjust to the suitable position and contradict with the terminal surface of work piece through rotating the slider for the device still can carry out further injecture to its degree of freedom when the anomalous work piece in terminal surface is faced.
