The limit plate is installed on one side of the fixture base. A support arm is arranged on the top of the limit plate, and a drill sleeve is arranged on the support arm. The drill sleeve is located above the avoidance hole. The conical block is pressed into the fixture base and the limit plate from the side through the side clamping mechanism.

[0006] The workpiece positioning groove is a V-shaped groove.

[0007] One end of the support arm is semicircular, and the other end of the support arm is detachably mounted on the top of the limiting plate through a set of screws.

[0008] One end of the support arm is provided with a drill sleeve mounting hole and a threaded hole, the drill sleeve is mounted in the drill sleeve mounting hole, and a clamping screw is screwed into the threaded hole to clamp and fix the drill sleeve.

[0009] The side clamping mechanism is a flat-mouth vise, the fixture base is placed in the flat-mouth vise, and the conical block is pressed tightly into the fixture base and the limit plate through the flat-mouth vise.

[0010] The limit plate is welded to one side of the fixture base.

[0011] The utility model has the advantages of accurate positioning of the conical block, fast drilling speed and reduced labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
