BACKGROUND OF THE INVENTION 
     (a) Technical Field of the Invention 
     The present invention relates to a fluorescent tube seat, and in particular, a fluorescent tube seat, which can retains a fluorescent tube being mounted at any angle, without adjusting the angle of the fluorescent tube in the process of installation. 
     (b) Description of the Prior Art 
     A conventional structure of a light tube seat is shown in FIG.  1 . For such conventional fluorescent light tube seat, after it has been used for a period of time, it possesses the following shortcomings, which are required to be improved. 
     When a fluorescent light tube a is to be installed to a conventional tube seat, the tube pins b of the fluorescent tube at one end thereof have to be in alignment with the insertion holes  1  of a spring-support seat  2  by using one hand, and the other hand of the user is used to hold the spring-seat  2  for the other end of the light tube seat. In other words, both of the hands have to be used in installing the fluorescent light tube into the light tube seat. In addition, the light tube pins are not easily made in alignment with the insertion holes of the fluorescent tube seat. Thus, it is rather time consuming and inconvenience to mount the fluorescent light tube into the tube seats. 
     Another type of conventional light tube seat is the rotatable light tube seat, which is shown in FIG.  2 . When a fluorescent light tube is mounted, the light tube pins b of the light tube a are respectively in alignment with guiding slots  3  and then the pins b are rotated until the pins b are in contact with conducting plates at the light tube seat. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide an improved structure of a fluorescent light-tube seat comprising a base seat, a panel, an axle, an engaging peg, a spring, a hole cover, an “Π”-shaped member, two conducting copper plates, wherein two fluorescent light-tube seats are used as one module to facilitate the installation of the fluorescent light-tube tube by vertically pushing action of the fluorescent light-tube tube.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIGS. 3 and 4, there is shown an improved structure of a fluorescent light-tube seat comprising a base seat  10 , a panel  11 , an axle  12 , an engaging peg  13 , a hole cover  14 , a spring  15 , a “Π”-shaped member  16 , and two conducting copper plates  17 , wherein the base seat  10  having a front end being provided with a “Π”-shaped recess, and the bottom end of the lateral wall of the recess being a curved surface, and the center area of the top end of the seat body being a cylindrical slot in communication with the “Π”-shaped recess, the bottom end of the cylindrical slot being provided with a protruded edge, and the walls of the cylindrical slot being provided with two kinds of fibs of different height and thickness such that a lower rib is located in between two higher ribs, forming three ribs which are spaced apart and arranged on the walls; 
     As shown in the figure, the panel  11  has two parallel straight guiding slots  111  with a distance equals to the distance of the tube pins, and a mounting block  113  is provided in between two guiding slots  111 , the lateral sides of the mounting block  113  is provided with an engaging slot  114 , and the bottom edge thereof forms a slanting angle  115  toward the interior thereof. 
     The axle  12  is pivotally mounted at the hollow tube body of the cylindrical slot  104  and the top edge of the slot  104  is formed into 6 wave-like elements and the external edge surface of the tube body is formed into a plurality of corresponding teeth structures and a rail  123  is provided thereon. The engaging peg  13  is a hollow peg body mounted onto the top end of the axle  12 , and the top end of the peg  13  has a cap edge having a diameter smaller than that of the cylindrical slot  104 , and the circumferential edge of the cap edge is formed into tree engaging teeth structures  132 . 
     The hole cover  14  has a surface provided with openings  141  for wires. In accordance with the present invention, the spring  15  is urged between the top end of the engaging peg  13  and the hole cover  14 , and the “Π”-shaped member  16  is mounted at the bottom end of the axle  12 , and it reciprocates within the “Π”-shaped recess  101 . The two conducting copper plates  17  has a bottom end which form into an arch-shaped structure  171  and is mounted at the sides of the “Π”-shaped member  16 . 
     In accordance with the present invention, the operation of the structure of the bulb-seat is explained hereinafter. FIG. 7 shows the structure of the present invention where the fluorescent light tube has not been mounted. In accordance with the present invention, the engaging peg  13  compresses the engaging teeth  132  having the spring  15 , and the teeth  132  urges the top edge of the protruded rib d and is mounted at the “Π”-shaped member  16  between the mounting block  113  and the “Π”-shaped recess  101 . By mean of the arch-shaped corner  171  at the bottom end of the two conducting copper plates  17  and the curved surface face  103  at the two lateral sides of the “Π”-shaped recess  101 , sufficient support is provided to the mounting block  113  to allow the light bulb seat to be slightly pushed toward. In application, two tube seats are employed as a module and are located to face the panel  11 . To mount the fluorescent tube, as shown in FIGS. 7 to  9 , the angle of the tube pin may not be adjusted, but it is directly pushed to the end and release the pushing action. The mounting of the fluorescent tube is achieved by the guiding of the guiding corner  115  at the bottom end of the mounting block  113 , and the tube pins b smoothly slide into the two guiding slot  111 . When the “Π”-shaped member  16  is pushed to the end by the tube pins b, the engaging teeth  132  of the engaging peg  13  is blocked by the teeth  122  at the circular edge on the axle  12 , and rotated along the top edge of the protruded edge c such that the compressed spring  15  is released. 
     Thus, when the fluorescent tube is released, the engaging peg  13  which compresses the “Π”-shaped member  16  and the conducting copper plates  17  are lowered altogether. Before the tube pins b are lowered to the engaging slot  114 , the bottom end edge of the two conducting copper plate  17  protrude out earlier along the curved surface  103  and engage with the engaging slot  114  so as to cut off the forward movement of the fluorescent tube. The tube pins b located at the conducting copper plates  17  are appropriately pressed by the member  16  to ensure that the tube pins b are in contact with the conducting copper plates  17 . To disengage the fluorescent tube, the fluorescent tube is pushed upward to the end. In this operation, the “Π”-shaped member  16  is pushed to the top together with the conducting copper plates  17 , the axle  12 , and the engaging peg  13 . The teeth  132  is rotated and is located at the top edge of the protruded rib c as a result of the teeth  122  at the circular edge of the axle  12 , and urged against the top edge of the protruded rib. At the same time, the spring  15  is restored to its original shape and thus, the “Π”-shaped member  16  can maintain at the top position as a result of the arch-shaped corner at the bottom end of the copper plates  17  and the curved surface  103  which provides sufficient force to support the member  16 . Thus, when the fluorescent tube is pushed to the top end, it can be dismantled therefrom. 
     In accordance with the preferred embodiment, the connection of the power source wire of the two conducting copper plates  17  is achieved by allowing the wire to pass into the through hole  141  of the hole cover and then connected at the engaging peg  13 , or, the base seat  10  is provided with a through hole for the connection of power source wire. 
     While the invention has been described with respect to preferred embodiment, it will be clear to those skilled in the art that modifications and improvements may be made to the invention without departing from the spirit and scope of the invention. Therefore, the invention is not to be limited by the specific illustrative embodiment, but only by the scope of the appended claims.
