of the second core 2202 is provided with four round through holes, the first core 2201, the support plate 2101 and the second core 2202 are matched and connected through a cross screw 2203, considering that the first core 2201 and the second core 2202 are matched and are symmetrical about the middle section of the fish body, and the support plate 2101 is arranged at an offset distance on one side of the middle section of the fish body, so the width of the first core 2201 is two offset distances greater than the width 2202, the upper part of the first core 2201 and the second core 2202 form a cabin body, one side of which is provided with a notch, the depth of the notch is larger than the width of a first elastic fiber material 2207, the width of the notch is equal to the thickness of the first elastic fiber material 2207, two through holes are respectively arranged at two ends of the first elastic fiber material 2207, a first rudder disk connecting block 2206 is placed in the

glue, the position of the first fixing piece 2209 in the glue is further reinforced, and then the first elastic fiber material 2207 is firmer, and considering that the first rudder disk connecting block 2206 needs to be connected with the first elastic fiber material 2207 fixed in the glue, and simultaneously needs to be connected with the driving module, the first rudder disk connecting block 2206 cannot be detached from a fish body after the glue injection operation is completed along with the first core 2201 and the second core 2202, and cannot be wrapped by the glue, so that a part for preventing the glue from entering the cabin body is arranged at the cabin body where the first rudder disk connecting block 2206 is placed, and considering that after the glue injection operation is completed, the part is conveniently taken out from the periphery of the first rudder disk connecting block 2206, so that the part is divided into two parts, namely the first rudder disk sleeve 2204 and the second rudder disk sleeve 2205, and the first rudder disk connecting block 2206 is wrapped by the first rudder disk connecting block 2206 sleeve and the second rudder disk sleeve, the first rudder disk sleeve 2004 and the second rudder disk sleeve 2005 are both provided with bosses which are matched with the rest part of the notch to seal the cabin body, and because the first rudder disk sleeve 2204 and the second rudder disk sleeve 2205 are required to be taken down after the glue injection operation is finished, the absolute tightness of the cabin body cannot be ensured through the matching of the first rudder disk sleeve 2204 and the second rudder disk sleeve 2205 with the cabin body, it is noticed that in the glue injection operation, the glue injection liquid level is from bottom to top, meanwhile, the viscosity coefficient of the glue injection is large, the air in the cabin body cannot be completely removed, a little glue injection enters the cabin body, but no influence is generated on the work of the first rudder disk connecting block 2206.
