The hole is further recessed in the middle of the front right side of the rotating disk and the middle of the front left side respectively, and an adjusting long groove extending in the left and right directions is respectively arranged, and the long groove is adjusted to the right side in the middle of the right side of the outer peripheral surface of the rotating disk and the middle of the left side. The right end and the left end of the left adjustment slot are provided with an adjustment screw hole, each adjustment screw hole is a screw hole extending in the left and right directions; and a spindle head is provided with a vertical and rear planar spindle head body, The width of the left and right sides of the spindle head body is narrower than the width of the left and right sides of the rotating disk, and a locking plate is protruded outwardly on the left and right sides of the rear side of the spindle head body, and the two locking plates are located on the rotating disk. Right in front of the right side, the two lock plates respectively are provided with a plurality of bolt perforations corresponding to a plurality of fixing screw holes on the left and right sides of the rotating disc, and a fixing bolt is arranged corresponding to each bolt through hole, and each fixing bolt passes through each bolt The perforation and the screw lock are positioned in the respective fixing screw holes, and two adjusting block insertion holes are fixed in the left and right positions corresponding to the two adjusting long grooves behind the main shaft head body, and the adjusting block insertion holes are embedded in the left and right sliding manners. In the long groove, an adjusting bolt is screwed into each adjusting screw hole, and the inner ends of the adjusting bolts are positioned against the side faces of the adjusting blocks.

Further, the present invention is disposed on the right side of the front side of the rotating disk a plurality of fixing screw holes are disposed on the circumference of the rotating disk and arranged in a circular arc shape; a plurality of fixing screw holes penetrating the right side of the rotating disk are also disposed on the periphery of the rotating disk Arranged in a circular arc.

Further, the present invention has two adjustment block insertion holes corresponding to the left and right positions of the two adjustment long grooves behind the spindle head body, and the shape of each adjustment block insertion hole is the same as each adjustment long groove and is located in each adjustment long groove. Directly in front of the adjusting block, the adjusting blocks are embedded in the middle of the adjusting block inserting holes, and the adjusting blocks are screwed through the adjusting blocks to be coupled to the middle of the front of the adjusting block inserting holes.

Further, the present invention is provided with an auxiliary long groove on the lower side of the front surface of the rotating disk, the auxiliary long groove is an elongated groove extending in the left and right directions; corresponding to the lower side behind the spindle head body An auxiliary block is fixed in the position of the auxiliary long groove, and the auxiliary block is embedded in the auxiliary long groove in a left and right sliding manner.

Further, the present invention is provided with an auxiliary block insertion hole corresponding to the lower side position of the auxiliary long groove behind the spindle head body, and the auxiliary block is embedded in the middle of each auxiliary block insertion hole, and the bolt passes through each auxiliary The blocks are combined with the auxiliary block screw locks in the middle of the front inside the auxiliary block insert holes.

When the present invention is used, the left and right positions of the spindle head body coupled to the front of the rotating disk of the tool body can be slightly adjusted so that the left and right positions of the center of the spindle head body and the left and right positions of the center of the rotating disk are After the alignment. In operation, the fixing bolts are first loosened to the positions of the fixing screws, and the fixing of the fixing bolts and the fixing screw holes has a tolerance of dimensional tolerance. After positioning the block, you can slightly adjust the left and right positions.

Then, one of the adjusting bolts is loosened, and the adjusting block and the main shaft head body are moved to the left or the right by rotating the other adjusting bolts, so that the main shaft head body can be adjusted along the two adjusting slots of the rotating disc by the two rear adjusting blocks. Perform a corrective movement slightly to the left or right. When the left and right positions of the center of the spindle head body are aligned with the left and right positions of the center of the rotary disk, the two adjustment bolts are locked, and the spindle head body is opposed to The position of the rotating disc is fixed. At this time, the fixing bolts can be fixed to fix the position of the main shaft head to the front of the rotating disc, and the operation of finely adjusting the left and right positions of the main shaft head body is completed.

The utility model has the advantages that the two adjusting bolts can be sequentially rotated to push the adjusting block to finely adjust the position of the spindle head body. In addition, after adjusting the left and right movement of the spindle head body to an appropriate position, the spindle head can be fixed by two adjusting bolts in advance. The position of the body is such that the final locking bolt binds the spindle head body to the front of the rotating disk. Since the spindle head body has been positioned by the two adjusting bolts pressing the two adjusting blocks, the position of the spindle head body will not be left again. Right offset, the center position of the spindle head body can be adjusted in a practical and simple manner.
