     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The device according to the present invention, as shown in FIGS. 1,2, and 3 is mainly composed of a front cover (1), a frame edge (2), a front holder (4), a base casing (5), an upper housing (3) and a lower housing (3)&#39;, a back holder (6) and a back cover (7). The structure of the front cover (1) is as shown in FIGS. 2,3,4 and 5. The reflecting mirror (41) according to the present invention, comprises three bearing plates (411) and three protruding rods (412) with said three bearing plates (411) mounted in the track (42) at the front inner side of the cylindrical front holder (4). Said reflecting mirror (41) is then inserted into the front cover (1) through the frame edge (2) letting the reflecting mirror (41) and the front end of the cylindrical front holder (4) be allocated inside the front cover (1) and letting the frame edge (2) be arranged between the front cover (1) and the locking channel (43) of the cylindrical front holder (4). Said cylindrical front holder (4) comprises at its front edge an elastic element (44) made of plastic material, having a hollow body for allocation of said base casing (5). Said base casing (5) comprises a lamp socket (51) at the front end for allocation of a lamp holder (512) and a bulb (511) and two troughs (52) and (53). Trough (52) is arranged for allocation of booster coil (521) while trough (53) is for allocation of a booster circuit board (531). The base casing (5) comprises a ring plate (54) for allocation of the base casing (5) with the upper housing (3) and the lower housing (3)&#39; by inserting the ring plate (54) into the locating channel (31)&#39;. Base casing (5) also comprises a battery holder (55) for allocation of battery. The battery holder (55) itself comprises of two springs. Spring (551) and (552) for respective connection of the positive and the negative end of the battery to the circuit. Two conductor rods (553) and (554) are arranged bilaterally with springs (553) and (554) firmly attached to make them (conductor rods 553 or 554) flexible. The back holder (6) according to the present invention, is made up of two conductor plates (61) and (61)&#39; for connection to the battery and an elastic locking edge (62) to match with the hole (71) or (72) for allocation of the back holder (6) with the back cover (7). 
     Please refer to the sectional view and the fragmentary view of the front cover in FIG. 4 and FIG. 5. A lens (11) is mounted on the front edge cover (1) with shock blocks (12) connected at the circumference at a proper interval, in the present preferred embodiment, three shcok blocks are arranged. Each shock block (12) is mounted in a groove (13) with a conductor rod (14) arranged thereto, said conductor rods (14) are turned on by means of contact plates (15) while revolving, the contact plates (15) are connected to the booster coil (521) by means of electric wires. Please refer to FIG. 6 and FIG. 7 for the arrangment of the elastic element (44) and the reflecting mirror (41) of the cylindrical front holder (4) and the sloping block (16). The protruding rod (412) pushes the reflecting mirror (41) backwards when it is turned to the lowest position at the sloping block (16) of the extreme inner side (61). When the protruding rod (412) of the reflecting mirror (41) reaches the peak point (162), the reflecting mirror (41) is forced to move forward by means of the elastic element (44), thereby controlling the condensation or dispersion of the light from the bulb (511). 
     The housing (3), according to the present invention, comprises a built-in press-button (32) separated from it by a groove channel (33), thereby making the application of the press button (32) difficult to fail. The press button (32) is directed to the switching element (45) of the cylindrical front holder (4)&#39;. The structure of the switching element (45) is shown in FIG. 8 and FIG. 9. When the housing (3) and (3)&#39; are turned to rotate the spring leaf (451) of the switching element (45) is driven to move, letting the upper contact plate (452) and the lower right contact plate (453) get in contact with the upper contact block (4511). The lower contact block (4512) of the spring leaf (451) is for electricity conducting and to let the connected bulb (511) be turned on (as shown in FIGS. 2 and 3). When turning to another angle, the arc-shaped portion (141) of the shock rod (14) of the front cover (1) is driven to contact with the contact block (15) and the spring plate (451) then is driven to span over the lower left contact plate (452) and the lower right contact plate (453). Therefore, by pressing on the press button (32), the booster circuit (531) is turned on to produce high voltage electric shock. 
     Please refer to FIGS. 2, 10 and 11 for the structure of the back holder (6) and the back cover (7). The conductor rods (553 and 554) are arranged to penetrate through the holes (63 and 63&#39;) and directly welded to the negative and positive end of the circuit board (64) at the trough (65) of the back holder (6). the circuit board (64) is to provide a buzzer circuit for alarm. It comprises of two conductor plates (not shown in the drawings). When the back holder (6) and the back cover (7) are turned to their allocation as allocated at the slot (71). They are forced to press on the spring leaf (73) letting two control noses (731) and (732) of the spring leaf (73) move away from the circuit board. When the back cover (7) is drawn from the housing, the two control noses (731) and (732) of the spring leaf (73) are forced to contact the copper foil for electricity conduction and to let the buzzer circuit produce acoustic alarm. The buzzer (67) buzzes through the hole (66) of the speaker. 
     The booster circuit board (531), according to the present invention, is attached to the base casing (5) by a bolt (532) through the bolt hole (553)&#39;. The other parts are allocated by means of hook joint. For instance, each housings (3) and (3)&#39; comprises of respective retainer hooks (34) and retaining grooves (35)&#39; for easy assembly. In the present invention, the condensation of the light from the bulb (511) is controlled by revolving the front cover. The electric shock is controlled also by revolving the cylindrical front holder (4) prior to pressing the press-button (32). The acoustic alarm is controlled by drawing the back cover (7) from the housing. Through the described arrangement, the present invention could be controlled to provide electric shock for self-protection, acoustic alarm for help and the respective long-range and short-range lightening for illumination.
