We claim: 
     
         1 . A continuous feeding mechanism, comprising:
 a rotatable indent roller which is circumferentially provided with a plurality of grooves adapted to receive and hold therein an object; each groove is provided with a post pin therein; the post pin is connected with a spring; the spring is arranged towards an interior of the indent roller; and the post pin is movable along the blanking grooves;   a feeding box, wherein a bottom is hollow, and the bottom is arranged above the indent roller or the bottom is fixedly connected with the indent roller;   a positioning shaft sleeve arranged in the indent roller and provided with a slide block; and   an adjusting rotating shaft which is circumferentially provided with an eccentric sleeve and arranged in the positioning shaft sleeve; the slide block contacts the eccentric sleeve; in a normal state, the slide block is contactable with the spring; the indent roller rotates to drive the post pin and the spring to rotate around the positioning shaft sleeve; and when the post pin rotates for a set angle, the spring contacts the slide block, and the slide block pushes out the post pin with the spring, so that the objects received in the grooves are pushed out.   
     
     
         2 . A continuous feeding mechanism, which is adapted to receive and transfer objects from a source to a designated conveying device, the continuous feeding mechanism comprising:
 a rotatable pulley, which has an external circumferential surface in which a plurality of grooves are formed, the plurality of grooves having openings formed in the external circumferential surface, such that rotation of the rotatable pulley brings the openings of the plurality of grooves to sequentially receive the objects from the source;   a plurality of pushing pins, which are respectively and movably received in the plurality of grooves, each of the plurality of pushing pins being connected to and supported by a spring to be set at a home position; and   a slide block, which is arranged at a working position relative to the rotatable pulley, such that the rotation of the rotatable pulley causes the plurality of pushing pins to sequentially approach and get in contact with the slide block at the working position, wherein the contact of the slide block with each pushing pin of the plurality of pushing pins causes a movement of said each pushing pin in the respective groove from the home position to a dump position, where the object received in the respective groove of said each pushing pin is forced out of the respective groove by the movement of the pushing pin.   
     
     
         3 . The continuous feeding mechanism according to  claim 2 , wherein the slide block is arranged in a hollow interior of the rotatable pulley to point toward an internal circumferential surface of the rotatable pulley in a radial direction, the slide block being movable in the radial direction, and wherein an eccentric cylinder is eccentrically arranged in the hollow interior of the rotatable pulley and is rotatable relative to the slide block, the eccentric cylinder having an outer circumferential surface that defines a camming contour, the slide block being in contact engagement with the camming contour of the eccentric cylinder, such that the slide block is movable in the radial direction with the rotation of eccentric cylinder. 
     
     
         4 . The continuous feeding mechanism according to  claim 3 , wherein the eccentric cylinder comprises a rotating shaft and an eccentric sleeve mounted on the rotating shaft, the eccentric sleeve defining the camming contour. 
     
     
         5 . The continuous feeding mechanism according to  claim 2 , wherein the rotatable pulley is of a hollow cylindrical form having a hollow interior defined and delimited by an internal circumferential surface that is opposite to the external circumferential surface in which the plurality of grooves are formed, the plurality of grooves having openings formed in the external circumferential surface, such that the rotation of the rotatable pulley brings the openings to sequentially correspond to and face the source for receiving the objects therefrom; and wherein the slide block at the working position is located in the hollow interior of the rotatable pulley and having an end pointing in a radial direction of the hollow cylindrical form toward the internal circumferential surface, the plurality of pushing pins being rotatable with the rotatable pulley to sequentially contact with the end of the slide block. 
     
     
         6 . The continuous feeding mechanism according to  claim 5 , wherein each pushing pin of the plurality of pushing pins is supported by a spring, such that said each pushing pin is restored from the dump position back to the home position by the spring. 
     
     
         7 . The continuous feeding mechanism according to  claim 2  further comprising a feeding box, which receives and holds the objects from the source, wherein the feeding box has an opening corresponding to and facing external circumferential surface of the rotatable pulley, such that the rotation of the rotatable pulley brings the openings of the plurality of grooves to sequentially correspond to and face the opening of the feeding box to receive the objects from the feeding box.
