The belt 8 facilitates the synchronous rotation of the several turntables 7. The ring wall of the several turntables 7 is fixedly fitted with abutment ring 20, and the belt 8 is fitted and abuts against the abutment ring 20 to prevent the belt 8 from detaching from the turntable 7;

[0037] The tapping secondary spindle 9 is mounted on the rear turntable 7 using the connecting assembly 10, and is installed on the rear slider 6 according to the processing requirements.

[0038] The lead screw 11 is screwed onto the crossbar of the support frame 1 using a bearing seat, and the right slider 6 is threaded onto the lead screw 11. The two ends of the connecting rod 12 are respectively screwed onto the two sliders 6 using hinge seats.
