Taking JP 5598637B and CN 105008628B as an example, the nozzle system disclosed in the patent is assembled on the nozzle bracket in a suspended manner, so that the nozzle body can be placed in the nozzle bracket. It is easy to cause structural instability and yaw during displacement. In addition, the nozzle device only uses a single gear to drive the rack to displace the nozzle body, but conventionally uses a single gear to be driven by the motor, which is easy to cause the conventional patent to be unable to prolong the life of the motor by changing the gear ratio.

Furthermore, although the structure disclosed in JP5565707B uses a plurality of gears to drive the nozzle so that the nozzle body can be displaced relative to the nozzle support, and a space for storage is formed on one side of the nozzle body, the space is used for the driving gear and rack of the nozzle body. Store it in when not in use. However, according to the drawings in the specification, it can be found that the space does not have any guiding structure, that is, when the rack is accommodated in the space, the rack is not restricted in its position, and the rack is There is a possibility of shifting or inadvertent interference with other components.

In addition, according to the structure disclosed in TW I426959, it can be found that the rack track of the nozzle bracket is linear, so that the conventional rack cannot be accommodated when the nozzle body is not driven to extend relative to the nozzle bracket, resulting in a larger overall volume of the nozzle device. A larger assembly space is required, which makes the conventional nozzle device difficult to install.

In view of this, the applicant of this case tried his best to think about an improvement method in order to overcome the defects of the previous patent, and thus the present invention came into being.
