As a specific embodiment of the present invention, a second auxiliary unit 18 is disposed at the third half-ring 152 and the fourth half-ring 154, and the second auxiliary unit 18 includes a first rope 181 and a swinging plate 182; the swinging plate 182 is rotatably mounted in a first groove formed in the fourth semicircular ring 154 through a rotating shaft, and a torsion spring is sleeved on the rotating shaft; one end of the first rope 181 is wound on the rotating shaft, and the other end of the first rope 181 is connected with the first auxiliary block 171.

By adopting the technical scheme, when the two first auxiliary blocks 171 move back to back, the rotating shaft can be pulled due to the existence of the first rope 181, so that the swinging plate 182 is close to one side of the turbine rotating shaft 14, the turbine rotating shaft 14 is further clamped, and the overall stability is improved.

In an embodiment of the present invention, each of the swing plates 182 has a rectangular elastic block 183 and a triangular elastic block 184 alternately disposed thereon.

By adopting the above technical scheme, when the swing plate 182 moves to a side close to the turbine rotating shaft 14, the rectangular elastic block 183 and the triangular elastic block 184 are extruded and deformed, so that the contact area with the turbine rotating shaft 14 becomes larger, the friction force is increased, the clamping degree of the turbine rotating shaft 14 is further improved, and the overall stability is improved.

The working principle is as follows: when the invention is used, firstly, the box cover 2 is opened, the turbine 10 is placed into the turbine rotating shaft fixing chamber 13, then the box cover 2 and the box body 1 are fixed through the four groups of screws 3, then the screws 122 in the first fixing device 12 are screwed, the lower end of the turbine 10 is fixed, the tightness of the connection between the box cover 2 and the box body 1 can be ensured through the four groups of screws 3, downward pressing force is generated, the turbine 10 is fixed by matching with the first fixing device 12, the fixing effect is improved, the welding parts at two sides can be ensured to be normally welded through the arrangement of the elliptical welding holes 16, the abutting effect is further improved through the practicability of the device, the second movable cavity 123, the abutting plate 124, the second movable plate 125, the first semicircular ring 126, the second semicircular ring 127 and the connecting plate 128 are arranged, the lower end of the turbine 10 is fixed on the outer surface of the fixed second semicircular ring 127 by the downward action of the moving first semicircular ring 126, so that the first fixing device 12 can be ensured to tightly support turbines 10 with different sizes, the tight equipment does not need to be replaced when the turbines 10 with different sizes are tightly supported, the practicability of the first fixing device 12 is improved, the first semicircular ring 126 and the second semicircular ring 127 are arranged to mutually clamp, the tight degree can be ensured when the turbines 10 are tightly supported, so that the welding effect of the turbines 10 and the turbine rotating shaft 14 is improved, the cylinder 151, the third semicircular ring 152 and the fourth semicircular ring 154 are arranged, when the turbine rotating shaft 14 is put in, the cylinder 151 drives the third semicircular ring 152 and the fourth semicircular ring 154 to move forwards, the turbine rotating shaft 14 is clamped, the turbine rotating shaft 14 can be well tightly supported and fixed, and the structures of the first fixing device 12 and the second fixing device 15 are simple, dismantle the convenience, the practicality is higher, through setting up first activity cavity 4, first spring 5 and first fly leaf 6, because first fly leaf 6 is through first spring 5, can be in first activity cavity 4 free activity, can guarantee on the one hand also can be supported tightly to vertical to turbine 10 to further improve the tight effect of supporting of integrated device, on the other hand need not change when supporting tight not unidimensional turbine 10 and support tight equipment, thereby improve the practicality of totality, the welding begins at last.
