[0002] Gears are a common power transmission method, and their structures are diverse and numerous. They can be classified according to their shape, tooth line shape, the surface on which the teeth are located, and the manufacturing method. According to their shape, they are divided into cylindrical gears, bevel gears, non-circular gears, racks, worm gears, etc.; according to the tooth line shape, they are divided into spur gears, helical gears, herringbone gears, bevel gears, and curved gears, etc.

[0003] For example, Chinese patent application No. 202420661839.9 provides a helical gear including a fixing component, an adjusting component, and a main body component. The fixing component includes a rotating shaft, a first groove, a first telescopic rod, a first spring, a first slide, a first slider, a first fixing block, and an external thread.

This technical solution allows the gear body to be installed on the rotating shaft by pressing the first fixing block into the first groove. By setting the first spring in the first groove, when the first fixing block is released, it pops out from the first groove, thus fixing the gear body. This utility model is simple to install, reduces the workload of workers, and improves the work efficiency of workers.

[0004] However, the following problems still exist in this technical solution: the length of the rotating shaft in this technical solution is fixed. Since different rotating shafts need to be installed on different shaft extruders, it has certain limitations in use. Summary of the Invention

[0005] The purpose of this invention is to provide a helical gear structure for a shaft extrusion press. The extension mechanism can extend the length of the first rotating shaft to make it applicable to different shaft extrusion presses and expand its application range.

The limiting mechanism includes a limiting ring provided on the outside of the first rotating shaft. The limiting ring has placement slots on both sides inside. A fixing block is inserted into each placement slot. One end of the fixing block passes through the limiting ring and extends out of one side of the limiting ring. The helical gear has installation slots on both sides inside. The fixing block is adapted to the installation slot for disassembling and installing the helical gear.

[0009] Preferably, a spring is fixedly provided at one end of the fixing block, and one end of the spring is fixedly connected to the inner wall of the limiting ring. A movable plate is fixedly provided on one side of the fixing block, and one side of the movable plate passes through the limiting ring and extends out of the limiting ring, for disassembling and installing the helical gear.

[0010] Preferably, the first rotating shaft is provided with an installation mechanism for fixing the helical gear. The installation mechanism includes a fixing ring on the first rotating shaft, a first fixing plate fixed on one side of the fixing ring, a second fixing plate passing through the outside of the first rotating shaft, and a third threaded hole on both the first fixing plate and the second fixing plate. The two connected third threaded holes are internally threaded with the same second bolt for fixing the helical gear.
