A gas flow adjusting device is provided, which includes a tube body, a first horizontal shaft, a second horizontal shaft, two leaf structures, a torsional spring and two linkage assemblies. The first and second horizontal shafts are disposed in an accommodating space of the tube body and spaced apart from each other along an axial direction of the tube body. The leaf structures are pivoted on the first horizontal shaft and have a swinging direction identical to the axial direction. The torsional spring is sleeved around the second horizontal shaft and provides a resilient force along the axial direction. The linkage assemblies are connected to the leaf structures respectively, and each of the linkage assemblies is connected to the second horizontal shaft and the torsional spring. Therefore, when the leaf structures swing to different angles, the twisting amounts of the torsional spring are minimally varied.

1. A gas flow adjusting device, comprising: a tube body, including two openings and an accommodating space between the two openings;a first horizontal shaft and a second horizontal shaft, which are disposed in the accommodating space of the tube body and spaced apart from each other along an axial direction of the tube body;two leaf structures, pivoted on the first horizontal shaft and having a swinging direction identical to the axial direction;a torsional spring, sleeved around the second horizontal shaft and providing a resilient force along the axial direction of the tube body; andtwo linkage assemblies, connected to the two leaf structures respectively, wherein each of the two linkage assemblies is connected to the second horizontal shaft and the torsional spring,wherein each of the two linkage assemblies includes a first link and a second link, a first end of the first link is pivoted on the second horizontal shaft and a second end of the first link is rotatably connected to a first end of the second link, and a second end of the second link is rotatably connected to one of the two leaf structures, and the torsional spring includes two cantilever portions which are connected to a joint where the first and second links of the two linkage assemblies are connected together. 2. The gas flow adjusting device of claim 1, wherein each of the two leaf structures is spaced apart from an interior surface of the tube body to form a gas passage, such that parts of the accommodating space at both sides of the two leaf structures keep in communication by the gas passage. 3. The gas flow adjusting device of claim 2, wherein the two leaf structures are pivoted on the first horizontal shaft in a slidable manner. 4. The gas flow adjusting device of claim 1, wherein each of the two leaf structures includes a leaf portion and a rotary joint, and the rotary joint is disposed on a side surface of the leaf portion and is rotatably connected to the second end of the second link. 5. The gas flow adjusting device of claim 1, further comprising two position limiting sleeves which are sleeved around the second horizontal shaft and the torsional spring is located between the two position limiting sleeves; wherein the first links of the two linkage assemblies are sandwiched by the two position limiting sleeves and the torsional spring. 6. The gas flow adjusting device of claim 1, further comprising two cushion sleeves disposed on the two cantilever portions respectively. 7. The gas flow adjusting device of claim 1, further comprising two cushion blocks which are disposed in the accommodating space of the tube body and between the two leaf structures and one of the two openings respectively; wherein the two cushion blocks abut on the two leaf structures respectively. 8. The gas flow adjusting device of claim 1, further comprising two cushion blocks which are disposed on the two leaf structures respectively; wherein the two leaf structures are located between the two cushion blocks and the two linkage assemblies. 9. The gas flow adjusting device of claim 1, further comprising at least one or two cushion sleeves which are sleeved around the second horizontal shaft; wherein the torsional spring is sleeved around the at least one or two cushion sleeves. 10. The gas flow adjusting device of claim 1, further comprising a cushion block which includes a first end and a second end opposite to the first end, wherein the first end is disposed on the first horizontal shaft, and the second end extends along a direction departing from the second horizontal shaft. 11. A gas flow adjusting device, comprising: a tube body, including two openings and an accommodating space between the two openings;a first horizontal shaft and a second horizontal shaft, which are disposed in the accommodating space of the tube body and spaced apart from each other along an axial direction of the tube body;two leaf structures, pivoted on the first horizontal shaft and having a swinging direction identical to the axial direction;a torsional spring, sleeved around the second horizontal shaft and providing a resilient force along the axial direction of the tube body; andtwo linkage assemblies, connected to the two leaf structures respectively, wherein each of the two linkage assemblies is connected to the second horizontal shaft and the torsional spring,wherein each of the two linkage assemblies includes a first link, a second link and a third link, a first end of the first link is pivoted on the second horizontal shaft and a second end of the first link is rotatably connected to a first end of the second link, a second end of the second link is rotatably connected a first end of the third link, and a second end of the third link is rotatably connected to one of the two leaf structures, and the torsional spring includes two cantilever portions which are connected to a joint where the first and second links of the two linkage assemblies are connected together. 12. The gas flow adjusting device of claim 11, wherein the third link further includes a protrusion which extends towards the leaf structure from the first end and/or the second end of the third link; the protrusion is configured to make contact with the leaf structure when the leaf structure rotates to a predetermined angle. 13. The gas flow adjusting device of claim 11, wherein each of the two leaf structures includes a leaf portion and a rotary joint, and the rotary joint is disposed on a side surface of the leaf portion and is rotatably connected to the second end of the third link.
