Abstract
A turret punch includes a first body, a second body, a third body, a pin, a first resilient member, a turret, function members, a second resilient member and a connector. The second rail portion of the third body is linearly movable along the first rail portion of the first body. When operating the first and second bodies, the function member that is located corresponding to the first function end moves linearly so as to be engaged with or to be disengaged from the first function end of the first body, such that the holes are punched along a straight line.
Claims8
A hand-held turret punch comprising:
- a first body having a first pivotal hole, a first function end formed at a distal end thereof, a first rail portion formed between the first pivotal hole and the first function end, each of two sides of the first rail portion having a first side and a second side which is parallel to the first side and faces the first side with a distance located therebetween, a third side formed between the first and second sides on each side of the first rail portion, a fourth side formed at an end of the first rail portion and being perpendicular to each of the first sides;
- a second body having a second pivotal hole which is located corresponding to the first pivotal hole, a control portion formed at a distal end of the second body and being a protrusion;
- a third body connected to the first body and having a second function end on a first end thereof, the second function end located corresponding to the first function end, a second rail portion formed in a second end of the third body, the first rail portion slidably engaged with the second rail portion, the second rail portion having inner portions each having a fifth side and a sixth side, the fifth sides slidably engaged with the first sides, the sixth sides slidably engaged with the second sides, a seventh side defined in each of the inner portions of the second rail portion and slidably engaged with the third sides, an eighth side formed at the second rail portion and slidably engaged with the fourth side, the second rail portion having a second control recess with which a portion with the second recess is accommodated, a third control recess defined in the second rail portion and communicating with the second control recess, the control portion being accommodated in the third control recess, when the second body is pivoted about the first pivotal hole, the control portion pushing the third control recess to linearly move the second rail portion along the first rail portion so as to move the second function end of the third body close to or away from the first function end;
- a pin extending through the first and second pivotal holes to pivotably connect the first body to the second body;
- a first resilient member located between the first and second bodies to resiliently bias the first and second bodies, and
- at least one function member located corresponding to the first function end of the first body, when a handle of the first body and a handle of the second body are pushed, the control portion of the second body controls and drives the second rail portion of the third body to move linearly along the first rail portion of the first body, so that the at least one function member located corresponding to the first function end is linearly engaged with the first function end to punch a straight hole.
