As shown in  FIGS. 1 to 7 , the terminal  100  of the present invention is used to connect to a conducting wire, the terminal  100  includes a base body  110 , a movable part  120  and a metal elastic part  130 . The metal elastic part  130  is disposed in the base body  110 , the movable part  120  is movably displaced reciprocally relative to the base body  110 . 
     Continuing, the base body  110  described above includes a casing  111  and a side cover  112 . The casing  111  has an accommodating space  101 , the accommodating space  101  forms an opening  102  on one side of the casing on one side of the casing  111 . The other side of the casing  111  has a first through hole  103 . 
     Additionally, the bottom of the casing  111  has at least one pin hole  104 , one end of the casing  111  has a passage bore  105  used for being passed through by the conducting wire, the passage bore  105  in in communicated with the accommodating space  101 . 
     Therefore, the side cover  112  is connected to the side of the casing  111  forming the opening  102  and covers the opening  102 , the side cover  112  has a second through hole  106  corresponds to the first through hole  103 . 
     One end of the movable part  120  is a pressing end  121 , the other end extends to form two arms  122 , one of the arms  122  is coupled to the side of the casing  111  having the first through hole  103 , the other arm  122  is coupled to the side cover  112 , and the inner side of two arms  122  respectively corresponds to the first through hole  103  and the second through hole  106  to form an abutment hole  123 . 
     The metal elastic part  130  is disposed in the accommodating space  101 , one end of the metal elastic part  130  has two abutments  131 , one of the abutments  131  passes through the first through hole  103  and abuts against one of the abutment holes  123 , the other abutment  131  passes through the second through hole  106  and abuts against the other abutment hole  123 ; the other end of the metal elastic part  130  has at least one pin  132 , and at least one pin  132  respectively passes through the corresponding pin hole  104 . The metal elastic part  130  may have a bent portion  133 , and two ends of the bent portion  133  each respectively extend to the end of the metal elastic part  130  having the abutment  131  and the other end having at least one pin  132 ; additionally, the casing  111  has a limiting convex portion  114 , and the metal elastic part  130  is set up around the limiting convex portion  114 . 
     In practical application of the terminal  100  of the present invention, when the conducting wire is to be inserted into the passage bore  105 , the pressing end  121  of the movable part  120  is pressed first, such that the movable part  120  is rotationally displaced downward relative to the base body  110 . During the rotation, due to abutment hole  123  of the inner side of two arms  122  in the movable part  120  abut against the abutment  131  of the metal elastic part  130 . Therefore, when the movable part  120  is rotationally displaced downward, the abutment hole  123  presses down on the abutment  131 , which allows one end of the metal elastic part  130  to approach the other end and to free up a space above, and then, when the conducting wire passes through the passage bore  105 , it can continue to penetrate into the upper space. 
     Next, the pressing end  121  can be loosened, and one end of the metal elastic part  130  which is originally pressed down, will be displaced upward due to not being pressed, and further abut against the conducting wire. 
     As shown in  FIG. 4 , the side of the casing  111  forming the opening  102  may have a plurality of engagement parts  107 , and the side cover  112  may have a plurality of engagement holes  108  corresponding to the plurality of engagement parts  107 . When the side cover  112  is connected to the casing  111 , each of the engagement holes  108  is engaged with the corresponding engagement part  107 . 
     Continuing to refer to  FIG. 4 , the other side of the casing  111  may have a shaft hole  109 , and the side cover  112  has the other shaft hole  109  corresponding to the shaft hole  109  of the casing  111  (As shown in  FIG. 5 ), the two arms  122  have axis parts  124  respectively corresponding to the shaft hole  109  of the casing  111  and the shaft hole  109  of the side cover  112  (as shown in  FIG. 6 ). When the movable part  120  is coupled to the base body  110 , the axis part  124  of one of the arms  122  is coupled to the shaft hole  109  of the casing  111 , and the axis part  124  of the other arm  122  is coupled to the shaft hole  109  of the side cover  112 . Wherein, the shaft hole  109 ,  109 ′ is disposed adjacent to one end of the passage bore  105 . 
     Referring to  FIG. 4  again, two sides of the casing  111  extend toward the top end to form an extension part  113 . When the pressing end  121  of the movable part  120  is not pressed, the movable part  120  will be rotationally displaced upward relative to the base body  110 , and two arms  122  will respectively abut against the corresponding extension parts  113 , and the movable part  120  stops the rotational displacement. However, the above are only illustrative examples and are not limiting. 
     According to the above description, terminal of the present invention works by pressing the movable part to press the metal elastic part downwards, resulting in the conducting wire being able, after entering the accommodating space through the passage bore, to penetrate more deeply in the space created by pressing the metal elastic part downwards; after releasing the movable part, the metal elastic part lifts up and clasps the conducting wire, thus achieving a more efficient method of connecting the conducting wire. 
     The above-mentioned embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement them according to the scope of the patent. That is, the equal changes or modifications made by the general in accordance with the spirit revealed by this creation should still be covered by the legal claims of this creation.
