The invention aims to provide an underwater diving propeller for a diver. The essence of the diver's underwater diving thruster is that the thruster is located above the scuba when in use and below the scuba when not in use. The replaceable battery pack is placed around the scuba diving apparatus. Rotation of the mover between the two positions is achieved by a contact hinge connecting the mover and the replaceable battery pack. By holding the control stick in hand, the diver can manage the device. There is a safety line with an annular snap hook attached to the control lever, which can be attached to a scuba diving inflatable life jacket. Thus, the diver can maneuver the device hands-free.)

2. Underwater vehicle for divers according to claim 1, characterized in that the thruster (SK) is moved about the hinge from the inactive position to the active position and vice versa only by the thrust of the thruster caused by the rotation of the propeller.

3. Underwater vehicle for divers according to claim 1 or 2, characterized in that the control joystick (UP) has two modes of operation, wherein the vehicle is controlled by pressing a button (up.11) and holding the press down, or by alternately pressing the button (up.16) to turn the vehicle on or off.

4. Underwater diving thruster for divers according to any of the previous claims, characterized in that the replaceable battery pack (BA) is placed at the bottom of the scuba diving apparatus (JE), so that the thruster (SK) and the replaceable battery pack (BA) can be connected at the rotating part of the contact hinge (sk.32) and the fixed part of the contact hinge (ba.20), without any extra cables outside the device.

5. Underwater submersible thruster for divers according to any of the preceding claims, characterized in that the contact hinge comprises a contact conductor, a hinge (sk.32) and a battery connector (ba.20) connecting the thruster (SK) and the replaceable battery pack (BA), the contact hinge being designed such that in the electrical connection between the thruster (SK) and the replaceable battery pack (BA) a rotation of the thruster (SK) about its transverse axis in both directions is provided between two positions, i.e. between an inactive position and an active position.

6. Underwater submersible thruster for divers according to any of the preceding claims, characterized in that a safety mechanism is also provided, comprising a quick release pin with spring ball (ba.19), a locking means (ba.18), two screws (ba.17), two safety screws (ba.15) and two spring plungers with ball (ba.16) on a replaceable battery pack (BA), a bolt plate with two bolt holes (sk.20) and a screw (sk.19) on the thruster (SK), which safety mechanism keeps the submersible thruster in the inactive position in case of transport, storage in a warehouse, preparation work before diving; wherein the quick release pin with spring ball (ba.19) must be removed before diving.

7. Underwater vehicle for divers according to any of the preceding claims, characterized in that it can only work in water, since two stainless steel contacts are inserted in the cradle (sk.30) for safety reasons and connected to the electric circuit of the motor controller, wherein water establishes an electric circuit between the stainless steel contacts, thus enabling the operation of the underwater vehicle.

8. Underwater submersible thruster for divers according to any of the preceding claims, characterized in that it is also provided with a locking mechanism, preferably with suitably shaped pin or screw balls, in order to lock the position of the thruster (SK) by interlocking them in a recess provided on the adapter bracket (ba.25) of the battery pack (BA); and wherein the connection between the pins or screw balls can be released by selecting an "inactive" button on the control lever (UP), pushing the pins or screw balls out of the grooves when the motor starts to rotate in the opposite direction.

9. Underwater submersible thruster for divers according to any of the preceding claims, characterized in that it is also provided with interchangeable inclined plates (ba.21) which in the active position ensure a proper lateral angle between the driving part of the submersible thruster, i.e. the thruster (SK), and the scuba diving (JE) of each diver.
