Automatic releaser with wireless controls

Automatic releaser with wireless controls, comprising a housing (8), rechargeable batteries (5), wireless controls, an electromagnetic mechanism, and a release mechanism, which is characterized in that

• the housing (8) is provided with a cylindrical configuration having a upper cavity (801) and a coaxially lower cavity (802) therewith, wherein said upper cavity (801) is communicated with the lower cavity (802) through a center hole (803), a top cover (2) and a bottom cover (12) are disposed at the top and bottom portions of the housing (8) respectively, an upper hanging ring (1) is fixed into the central portion of the top cover (2), the rechargeable batteries (5) are arranged within the upper cavity (801);
• the wireless controls includes a remote control, a control switch (19), antennas (21), and a wireless control module (3), wherein the control switch (19) and the antennas (21) are arranged into the top cover (2), the wireless control module (3) is disposed within the upper cavity (801);
• the electromagnetic mechanism includes an electromagnet (4) and an iron core (6), wherein the electromagnet (4) is arranged into the central portion of the cavity (801), the iron core (6) is disposed within the electromagnet (4);
• the release mechanism includes a release pin (13), a movable sleeve (10) and a release sleeve (9) sequentially suited to one another from inside to outside, wherein the release sleeve (9), of which top portion being connected with the iron core (6) and on which lateral wall two radial thru holes (901, 904) all in same size being arranged nearby the bottom cover (12), as well as on which outer wall an upper and a lower semicircle grooves (902, 905) being formed, are arranged within the lower cavity (802), wherein the upper semicircle groove (902) passes through the thru hole (901) in its diameter direction, and the lower semicircle groove (905) passes through the lower thru hole (904) in its diameter direction, a plurality of rubber rings are embedded within said two semicircle grooves (903, 906) respectively;
• the movable sleeve (10), on which lateral wall a pair of conical bores (1001) being symmetrically formed, is arranged within the release sleeve (9), wherein the external diameter of the conical bore (1001) adjacent to the release sleeve (9) is same as the thru holes (901, 904) and the internal diameter is smaller than the external diameter, a steel ball (11) of which diameter being smaller than the said inner side and bigger than the wall thickness of the movable sleeve (10) is disposed within each conical bore (1001);
• the release pin (13), at outer lateral of which a pair of semicircular grooves (1301) being symmetrically formed and of which lower end being connected with a lower hanging ring (16), is penetrated into the movable sleeve (10) through a release hole (1201) of the bottom cover (12), wherein the section radius of the semicircular groove (1301) is same as the steel balls (11).
