     a latch  60  accommodated in the notch  55  of the deadbolt  50 , a lock fringe  61  formed on a side of the latch  60 , wherein a slanted guiding face  62  is formed on an edge of the locking lock fringe  61 , and the locking lock fringe  61  is movably engaged with the engagement segment  57  of the deadbolt  50 , wherein the latch  60  further includes a second location protrusion  63  extending from a distal end of the latch  60 ; 
     a first resilient element  70 , a first end of the first resilient element  70  is positioned on the second positioning segment  56  of the slide cylinder  40 , and a second end of the first resilient element  70  is fixed on the first positioning segment  47  of the deadbolt  50 ; and a second resilient element  80 , a first end of the second resilient element  80  is positioned on the first locating protrusion  48  of the slide cylinder  40 , and a second end of the second resilient element  80  is fixed on the second location protrusion  63  of the latch  60 . 
     Referring to  FIGS.  5 - 6   , the deadbolt  50  is driven electrically to extend outward. The motor  30  of the control structure of the door lock is driven by a controlling signal of an electric circuit of a control unit A 1  so as to drive the guide rod  31  to rotate, and the guide rod  31  actuates the guide orifice  42  of the slide cylinder  40  so that the slide cylinder  40  drives the deadbolt  50  to extend out of the open segment  16  of the body  10 , as shown in  FIGS.  7 - 8   , when the slide cylinder  40  moves forward, the slide cylinder  40  pushes the deadbolt  50  to extend out of the open segment  16  of the body  10  by way of the first resilient element  70 . 
     As illustrated in  FIGS.  9 - 10   , the deadbolt  50  is driven electrically to retract backward, wherein the motor  30  rotates reversely to actuate the guide rod  31  so that the guide rod  31  drives the guide orifice  42  of the slide cylinder  40 , and the slide cylinder  40  actuates the deadbolt  50  to retract back to the open segment  16  of the body  10 , as shown in  FIGS.  11 - 12   , when the slide cylinder  40  retracts backward, the at least one horizontal trench  46  of the slide cylinder  40  engages with the at least one locking tabs  58  of the deadbolt  50  so that the slide cylinder  40  drives the deadbolt  50  to retract back to the open segment  16  of the body  10 . 
     Referring to  FIGS.  13 - 14   , the deadbolt  50  is driven manually to extend outward, wherein the hole  26 A of the shaft  25 A and the drive orifice  26  of the seat  25  are noncircular and are connected with a driven column A 21 , wherein the driven column A 21  has two lock knobs A 2  on two free ends thereof. When the two lock knobs A 2  are rotated manually, the seat  25  and the shaft  25 A are driven to rotate clockwisely or counterclockwise. When the seat  25  and the shaft  25 A are rotated clockwisely, the second paw  28  actuates the second driving extension  22 A of the slide partition  20  so that the slidable partition  20  moves forward to drive the two retaining portions  54  of the deadbolt  50  to push the deadbolt  50 , and the deadbolt  50  extends out of the open segment  16  of the body  10 . 
     With reference to  FIGS.  15 - 16   , the deadbolt  50  is driven manually to retract backward. When the seat  25  and the shaft  25 A are rotated counterclockwise, the first paw  27  actuates the two first spaced driving extensions  22  of the slidable partition  20  so that the slide partition  20  moves backward to urge the two symmetrical hooks  24 , and the two symmetrical hooks  24  drive the two retaining portions  54  of the deadbolt  50  to retract backward. 
     As shown in  FIGS.  17 - 19   , the control structure of the door lock is accommodated in a door A 3 , and the deadbolt  50  and the latch  60  extend out of the door A 3 , wherein the door A 3  has the control unit A 1  arranged on an edge thereof, and the control unit A 1  has a control chip accommodated therein and configured to control the motor  30  to operate by using the controlling signal. The control structure of the door A 3  mates with the deadbolt  50  and a contact sheet A 6  of a door frame A 4  to open or close the door A 3 . When the deadbolt  50  moves into a receiving orifice of the door frame A 4 , the contact sheet A 6  forces the latch  60  to retract inward so that the lock fringe  61  of the latch  60  moves into the engagement segment  57  of the deadbolt  50  by using the guiding face  62 , such that the deadbolt  50  is locked by the lock fringe  61  of the latch  60 , and the deadbolt  50  does not move outward or backward with respect to the slide cylinder  40 . 
     While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
