Abstract: A working machine includes a base having a working table for supporting a work piece and having a tool disposed on top for moving downward to machine the work piece. A block is secured to the base and has another tool for being selectively rotated to machine the side portion of the work piece. The another tool may be selectively driven by a motor which may drive the tool for moving downward to machine the work piece. The block has a screw driven slide to engage with the track and includes two followers for allowing the block to be secured to different vertical tracks.

Abstract: An assembly machine for implanting pins has a casing, a retarder, a hopper, a guide pipe, a guide recess, a seat, a chuck device, and a link. The hopper has spaced driving bolts, spaced chutes on the cone-shaped portion, a seat connecting the cone-shaped portion, a block on the seat, a shaft adjacent to the block, a rod connecting the shaft. A stretch spring connects a cylinder which is adjacent to the block and a bolt which is disposed on the driving rod. A rod which connects the shaft is adjacent to a notch. The seat has a slot communicating with the recess. A gap is at the bottom of the slot. A movable plate is at the bottom of the seat, and a spring is at the bottom of the movable plate. The chuck device has a bottom plate, a chuck, an extensible plate, a notch at the front end of the extensible platel, a rear board, an upper board and a lower board. A funnel matches a pin-guiding device which is supported by a seat. The funnel receives a plunger.
