When the sliding ring gear 40 slides on the main shaft 30, the pull rod 50 can drive the ball socket 20 to rotate along the central shaft 31 on the main shaft 30.

In the structure of slidably assembling the sliding gear ring 40 on the main shaft 30, referring to fig. 5 and 6, two guide grooves 33 extending along the axial direction of the main shaft 30 are symmetrically arranged on the main shaft 30, two sliding bars 42 respectively slidably engaged with the guide grooves 33 are arranged on the sliding gear ring 40, and a short shaft 43 hinged to the pull rod 50 is arranged on each sliding bar 42.

When the main shaft 30 rotates, the ring gear 41 of the slide ring gear 40 can always mesh with the front drive spur gear 61 of the front drive shaft 60, and therefore the front drive shaft 60 does not interfere with the main shaft 30. The ball port 20 can be rotated to a certain angle, and then the front actuator 70 drives the ball port 20 to swing. For example, the ball port 20 is rotated to a position capable of swinging horizontally, and then the front actuator 70 drives the ball port 20 to swing horizontally, or the ball port 20 is rotated to a position capable of swinging vertically, and then the front actuator 70 drives the ball port 20 to swing vertically. In this way, the air flow direction adjustment range of the ball port 20 can be increased by superimposing the rotational movement of the main shaft 30 and the swing movement of the ball port 20.

In the tuyere reverse driving structure in this embodiment, after the rotation angle of the main shaft 30 and the swing angle of the tuyere 20 are superimposed, the wind direction of the tuyere 20 can be oriented in any direction.
