When the insert plate 15 contacts the inclined surface of the locking block 21, the insert plate 15 pushes the locking block 21 upward, the second spring 20 is compressed, and the locking block 21 enters the limiting groove 19. When the locking groove 16 moves below the locking block 21, the locking block 21 enters the locking groove 16 under the elastic force of the second spring 20. At this time, the insert plate 15 is fixed, thus preventing the insert plate 15 from falling off and improving the stability of the connection.

[0025] Example 2, as Figures 1-4 As shown, further, a retaining ring 17 is fixedly installed at one end of the fixed base 4 near the connecting base 5, and a sealing groove 10 is opened at one end of the connecting base 5 near the fixed base 4, and a sealing ring 11 is fixedly installed on the inner wall of the sealing groove 10.

[0026] Furthermore, a storage slot 12 is provided at one end of the fixed base 4 near the connecting base 5. Three evenly distributed first springs 13 are fixedly installed on both sides inside the storage slot 12, and a shock-absorbing pad 14 is fixedly installed between the two sets of first springs 13.

[0027] Furthermore, batteries 18 are installed on both sides of the interior of the storage tank 12.

[0028] Furthermore, a motor 24 is installed inside the shock-absorbing pad 14. The output end of the motor 24 passes through the connecting seat 5 and enters the connecting seat 5, where a rotating frame 25 is fixedly installed.
