An angle-adjustable fixture device for needles comprising:
- a body, multiple piston elements, multiple needle elements, multiple air valves, a fixing element, a rotatable element, a positioning element, a resilient element, and a support element;
- wherein a body includes multiple air chambers staggeredly defined on two sides thereof, and a respective one air chamber is configured to accommodate a respective one piston element, wherein the respective one air chamber has multiple through orifices extending from a lower end of the respective one air chamber and configured to receive the multiple needle elements, inner threads formed on an upper end of the respective one air chamber and configured to screw with the multiple connection elements, and two air orifices extending from the body to correspond to the upper end and the lower end of the respective one air chamber and configured to accommodate the multiple air valves, wherein a middle section of a top of the body receives the fixing element;
- wherein the respective one piston element includes a large-diameter disc and a small-diameter column, and two grooves respectively defined around the large-diameter disc and the small-diameter column to fit with the multiple washers, such that the piston element is airtight with the respective one air chamber, wherein the small-diameter column has two receiving orifices corresponding to the multiple through orifices and configured to receive the multiple needle elements;
- wherein a respective one needle element includes a tip formed on an end thereof;
- wherein an end of a respective one air valve is configured to screw with a respective one air orifice, and the respective one air valve includes an air feeding tube fixed on the other end thereof and configured to pressurize airs into the respective one air chamber so that the respective one piston element is pushed downward or upward by the airs to extend forward or extract backward;
- wherein the fixing element includes a non-circular orifice formed on a center thereof to connect with the positioning element;
- wherein the rotatable element includes an opening defined therein, and multiple cutouts equidistantly defined around the opening, wherein the rotatable element is screwed with the support element, and the rotatable element includes multiple third threaded orifices defined on a top thereof;
- wherein the support element includes multiple second spot-faced holes corresponding to the multiple third threaded orifices of the rotatable element and configured to fix the rotatable element;
- wherein the positioning element includes a shank extending from a bottom thereof, a coupling face formed on the shank to correspond to and to be received in the non-circular orifice of the fixing element, multiple stems extending from an outer wall of the positioning element to be received in the multiple cutouts, and an accommodation notch defined on a top of the positioning element to accommodate the resilient element;
- and
- wherein the support element includes a trench corresponding to the accommodation notch of the positioning element and configured to accommodate the resilient element.
