     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A preferred embodiment of a press-style auxiliary lock in the present invention, as shown in FIG. 1-6, includes an outer housing  1 , an inner housing  2 , an engage means  3 , a drive means  4 , a press member  5 , a grip  50 , a position guide plate  51 , two interactive rods  6  and  60 , a decorative cover  7 , a hook  8 , a connect rod  9  and a hook rod  10  as main components. 
     The outer housing  1  and the inner housing  2  are combined with each other to become integral. The outer housing  1  has a cylindrical member  12  extending to the front to combine with a press member  5  attached with the grip  50  (as shown in FIGS. 43,  44 ). Two projecting blocks  13  are provided in the cylindrical member  12  for the press button  5  to fit in to combine the press member  5 . Further, the cylindrical member  12  has a curved groove  14  formed in an inner lower wall to combine a position guide plate  51  therein. The outer housing  1  has a position room  15  respectively formed at two sides respectively for the left and the right interactive rods  6  and  60  to fit therein, and a semicircular aperture  16  formed at two side walls for a connect rod  9  located between the interactive rods  6  and  60  and the hook  8  to extend therein. 
     As shown in FIG. 3, the outer housing  1  and the inner housing  2  are combined together as integral, and the outer housing  1  has a hollow cylinder  12  fixed at the front for fitting the press member  5  with the grip  50  as shown in FIGS. 43,  44 . A curved groove  14  is formed in a lower wall of the cylindrical member  12  to combine a position guide plate  51 . Further, the outer housing  1  has a position room  15  respectively at two sides for the left and the right interactive means  6  and  60  to fit therein, and a semicircular aperture  16  respectively formed in two side walls for the connect rod  9  provided between the interactive rods  6 ,  60  and the hook  8  to extend therein. 
     The inner housing  2 , as shown in FIGS. 4-6, has a drive means room  21  to contain the drive means  4 , and a position room  22  formed each at two sides of the room  21 , and an aperture  23  formed respectively in two side walls for the connect rod  9  provided between interactive rods  6 ,  60  and the hook to extend therein, and an opening  24  formed in a front upper wall for the engage means  3  to move in and out. 
     Next, as shown in FIGS. 7-12, a threaded rod  52  is provided to extend forward from the press member  5  to screw in a threaded hole  501  of the grip  50  as one unit of a press structure as shown in FIGS. 43,  44 . The press member  5  has a guide block  53  on an upper side, and a guide hole  54  at two sides of the guide block  53  for the projecting blocks  13  of the hollow cylinder  12  to fit therein. The press member  5  further has a slope  55  formed in a rear portion for the drive means  4  to slide along upward, and a guide block  56  formed under the lower surface to fit and move in a guide rail  511  of the position guide plate  51  .to let the press member  5  pressed in and secured or released to move out. Further, a spring  57  is provided between the press member  5  and the inner wall of the inner housing  2  to let the press member  5  easily pushed outward elastically. 
     The engage means  3 , as shown in FIGS. 15-18, has a hole  31  opening downward each at two sides for a coil spring  30  located between the engage means  3  and the drive means  4  to fit and located therein, and a drive means room  32  formed in a front half portion for the drive means  4  to extend therein when the drive means  4  rises up, so the drive means  3  not only rotates for hooking when rises up, but also pushes up the engage means  3 , which then cannot descend and protrudes firmly up to insert. 
     The drive means  4  shown in FIGS. 19-22 has an upper block  41  to rise and extend in the room  32  of the engage mans  3  to push up the engage means  3  from under, and an aperture  42  formed each in two lower sides for receiving posts  61 ,  601  of the interactive rods  6 ,  60  therein stabilized, a curved contact surface  43  formed each at two sides of a center hole to contact with the slope  55  of the press member  5  to engage the drive means  4  to move up together in case of the drive means  4  pressed, and a hole  44  formed each at two upper sides for the coil springs  30  to fit in. 
     FIGS. 23,  24 ,  25 ,  26 ,  27  and  28  show the left and the right interactive rods  6  and  60 , which have the same but asymmetrical structure and different size and thickness according to the space planned, while they act in the same way. The left and the right interactive rods  6  and  60  respectively have a post  61 ,  601  on an inner side for the aperture  42  of the drive means  4  to fit with, and an insert hole  62 ,  602  opening outward for one end of the connect rod  9  between the interactive rods  6 ,  60  and the hook  8  to insert therein. 
     A restrain plate  3 A shown in FIGS. 29,  30 , and  31  is for the engage means to engage with, having two elongate slots  3 A 1  and at leans one through hole  3 A 2  to secure the restrain plate  3 A on a preset location of an object to install this lock, and a lower edge  3 A 3  projecting down for a preset length. 
     The position guide plate  51  shown in FIGS. 32,  33 , and  34  is for controlling the press member  5  to be pressed in and secured in its place and pressed again to release to move up, having a guide rail  511  of a nearly triangular sealed route forming a three triangle with three points A, B, C and another triangle with other three points B, O, C. And the side AB is longer than OB (AB&gt;OB) and the side AC is longer than the side OC (AC&gt;OC), and the side BC is common. The points B and O respectively have a recess  512 ,  513  and a guide angle  514 ,  515  opposite to the recess  512 ,  513 . Then when the press member  5  is pressed in, the guide block  56  moves along the side AB into the recess  512 . But when the press member  5  is pressed again to release, the guide block  56  is guided by the guide angle  514  to slide into the recess  153  to let the press member  5  pressed in to secure at its place. If the press member  5  is further pressed, the guide block  56  moves outward along the guide angle  515  to the point C and then returns to the point A via the side CA. In this way the press member  5  is controlled in pressing and releasing to stabilize to its position. 
     The hook  8  shown in FIGS. 35,  36 , and  37  is clamped by a constrictor  80 , having one end formed with a insert hole  81  for one end of the connect rod  9  located between the interactive rods  6 ,  60  and the hook  8  to insert therein, as shown in FIG.  47 . 
     FIGS. 38 and 39 show a passive rod  10  to be hooked by the hook  8 , having a ratchet-shape post  101  formed in a rear portion and a front portion for the hook  8  to hook as shown in FIGS. 40,  41  and  42 . 
     Next, in using, when the grip  50  is not pressed in, the guide block  56  of the press member  5  is located at the point A of the guide plate  51 , with the drive means  4  not yet rising up, and with the curved contact surface  43  located near under the slope  55  of the press member  5 . And the engage means  3  may be moved to extend or shrink by means of the coil springs  30  by opening or closing a door or a window. 
     As shown in FIG. 44, when the grip  50  is pressed in, the press member  5  moves in at the same time, letting the drive means  4  rise along the slope  55  of the press member  5 , pushing up the engage means  3 , forcing the aperture  42  rotate the two interactive rods  6 ,  60  for a certain angle at the same time as shown in FIG. 46, and letting the connect rod  9  move the two hooks  8  at two ends hook the passive rod  10 , as shown in FIG.  47 . 
     The press-style auxiliary lock in the invention has the following advantages. 
     1. When the grip is not yet pressed in, the engage means may move along with a door, a cabinet, or a drawer to open or close, freely receiving expansion and shrinkage. 
     2. When the grip is pressed in, the drive means rises up to let two hooks hook the passive rod and rise to push up the engage means, which then cannot descend, achieving inserting engagement and hooking engagement synchronously. 
     3. Its structure is simple, and a single press action can perform double fixing effect (engaging and hooking). 
     While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be mad therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
