[0026] Specifically, the outer wall of one end of the worm 10 is meshedly connected with a worm wheel 11, the left end of the worm wheel 11 is fixedly connected with a transmission rod 12, the left end of the transmission rod 12 is fixedly connected with a first gear 13, the outer wall of the first gear 13 is meshedly connected with a spur rack 14, the top of the tapping table 7 is slidably connected with a second slide bar 16, the front and rear ends of the second slide bar 16 are slidably connected with the first slide bar 15, the left end of the spur rack 14 is fixedly connected to the right end of the tapping table 7, and the bottom end of the first slide bar 15 is respectively fixedly connected to the front and rear parts of the left side of the top of the fixed plate 3.
