[0026] Regarding the movement of the fixed plates 21: as shown in Figure 4 The device further includes a driving assembly. The driving assembly includes a reversible lead screw 41 and two moving plates 42.

The reversible lead screw 41 is arranged below the fixed table 1 in the left-right direction and passes through the two moving plates 42, and the two moving plates 42 are respectively connected with the two segments of the reversible lead screw 41. The reversible lead screw 41 can rotate. As shown in Figure 1 The fixed table 1 has a moving opening 11 penetrating through its upper and lower surfaces. The upper ends of the two moving plates 42 pass through the moving opening 11 and are respectively fixed with the fixed plates 21 of the two sets of fixed assemblies. The reversible lead screw 41 rotates, and the two moving plates 42 respectively drive the fixed plates 21 to move in the opposite direction along the reversible lead screw 41, that is, the fixed plates 21 of the two sets of fixed assemblies move inward synchronously or move outward synchronously.

[0027] Specifically, as shown in Figure 4 The driving assembly further includes two mounting frames 43, two bearings 44, and a motor 45. The two mounting frames 43 are fixed on the two sides of the bottom of the fixed table 1. The two ends of the reversible lead screw 41 are installed in the two mounting frames 43 through the two bearings 44 and can rotate relative to the mounting frames 43. The motor 45 is installed below the fixed table 1 and located outside any one of the mounting frames 43, and the output shaft is connected with the reversible lead screw 41 to drive it to rotate.

[0028] As shown in Figure 3 In a preferred embodiment, the upper surface of the fixed table 1 has two guide grooves 211 arranged in the left-right direction and respectively arranged at the front and rear ends of the fixed table 1. Two sliding blocks 212 are slidingly connected in the guide grooves 211 and are respectively fixed with the fixed plates 21 of the two sets of fixed assemblies. The fixed plates 21 move inward or outward along the guide grooves 211 under the action of the sliding blocks 212, and the guide grooves 211 limit the movement direction of the fixed plates 21, making the movement of the fixed plates 21 more stable. The moving opening 11 is located between the two guide grooves 211, and the two guide grooves 211 and the moving opening 11 respectively limit the front, middle, and rear sections of the fixed plates 21, fully guaranteeing the stability of the fixed plates 21 during the inward / outward movement.

The electric wire 311 of the wireless power supply 31 penetrates out of the bottom of the mounting table 33 and is fixed by the wire binding ring 34. The wire binding ring 34 is used to arrange the electric wire 311 of the wireless power supply 31.

[0034] In use, first, the bionic fish is placed between the two fixed plates 21 on the fixed table 1, and the wireless charging receiver 32 at the bottom of the bionic fish is placed on the top of the wireless power supply 31 for contact. Then, the motor 45 is started, the motor 45 drives the lead-screw 41 to rotate, the lead-screw 41 rotates to drive the two moving plates 42 to move inwards until the fixed plate 21 contacts the surface of the widest part of the bionic fish, preliminarily fixing the bionic fish. Then, the electric hydraulic telescopic rod 51 is started, the electric hydraulic telescopic rod 51 drives the pressing plate 22 to move inwards until it contacts the surface of the bionic fish, further pressing and fixing the bionic fish, so as to realize the overall fixation of the bionic fish during power supplement, avoiding the wireless power supply 31 and the wireless charging receiver 32 from being separated, resulting in power supplement failure. After all fixation, the electric wire 311 of the wireless power supply 31 is connected to an external power supply for power supplement of the bionic fish.
