3. the structure-improved of positioning device according to claim 1 is characterized in that, this pedestal is provided with skewed ring inclined-plane in the containing groove outside.

4. the structure-improved of positioning device according to claim 1, it is characterized in that, the positioning rod of this positioning rod group is convexly equipped with baffle ring in placing the body inboard, and the baffle ring opposite side is provided with the slippage body of rod with two long relatively side cuts and concave ring groove, and outside the slippage body of rod sheathed this elastomer, two long side cut outer side surfaces in the slippage body of rod are provided with inner bolt hole again, the relative interlocking of screw rod that protrudes out for bar head side.

5. as the structure-improved of positioning device as described in the claim 4, it is characterized in that this positioning rod is provided with the slippage body of rod of reduced outside diameter in baffle ring in placing the body opposite side relatively, for sheathed elastomer, and the neutral position of the slippage body of rod is concaved with concave ring groove.

6. the structure-improved of positioning device according to claim 1 is characterized in that this positioning rod group set spacing hole in limit body is the elliptical aperture shape, and oval poroid spacing hole is provided with the contraction lateral margin in relative both sides.

7. the structure-improved of positioning device according to claim 1, it is characterized in that, the limit body of this positioning rod group, inside has the contraction lateral margin towards the relative inner reduced width, long side cut for positioning rod cooperates the contraction lateral margin to become axial slide displacement, and the rotation positioning bar utilizes concave ring groove temporarily to be equipped in the spacing hole of limit body when sliding.

8. the structure-improved of a positioning device comprises pedestal and positioning rod group, it is characterized in that:

This base interior has through hole, and through hole one side is provided with the sidewall of tool spacing hole, and the outside side of pedestal is provided with the fixing part that outwards protrudes out;

This positioning rod group activity is arranged in the through hole of pedestal, and this positioning rod group is provided with and is arranged in the through hole side and extends outside positioning rod to place body, and be convexly equipped with the baffle ring that ammunition feed gonosome one side supports in the positioning rod outer rim, and elastomer in addition side promptly be held in the inner edge surface of sidewall of the through hole of pedestal, cooperate through hole to cut edge in the positioning rod outer installment again in the long of spacing hole shape of sidewall, and positioning rod is concaved with the concave ring groove for blocking spacing hole after the turn on long the side cut, then in the bar head of long side cut outer side surface in conjunction with the activity displacement in through hole of drive positioning rod.

9. as the structure-improved of positioning device as described in the claim 8, it is characterized in that this pedestal set spacing hole in sidewall is the elliptical aperture shape, and oval poroid spacing hole is provided with the contraction lateral margin in relative both sides.
