Abstract

A vise capable of perfectly, accurately, neatly and effectively clamping thereon a workpiece is provided. The vise includes a base having two side walls an angular scale-provided elongate body attaching thereon a first jaw member, a connecting rod pivotally connecting together the base and the body, a movable seat attaching thereon a second jaw member, two following gears rotatably but untranslatably attached to the body, two guiding screw rods mounted in the following gears and horizontally spacedly urging against the movable seat, a shaft rotatably mounted in the body and mounting thereon an active gear meshed between the following gears, a driving handle, a reinforcing locking member having a threaded hole, and a bolt passing through one of the side walls to be threaded into the threaded hole and capable of being rotated to tightly urge the body against the one side wall.

Claims

1. A vise comprising:

a base having two side walls and a base line for an aligning purpose;

an elongate body having a first end, a second opposite end having an intermediate hole and side holes, a middlely longitudinal through groove, and two end side plates one of which is provided with an angular scale capable of being utilized together with said base line to indicate an angle included by said base and said elongate body;

a connecting rod pivotally connecting together said base and said elongate body and capable of allowing said side walls to fixedly clamp therebetween said side plates;

a movable seat having a lower engaging piece which includes two side extensions and is capable of being slidably guided in said groove;

two following gears rotatably, untranslatably and horizontally spacedly attached to said second end;

two guiding screw rods respectively passing through two side holes, screwedly rotatably and respectively coaxially mounted in said following gears and respectively having one ends thereof capable of horizontally spacedly urging against said movable seat;

a shaft rotatably mounted in said second end and passing through said intermediate hole;

an active gear mounted on said shaft and meshed between said following gears;

a driving handle connected to said shaft;

a first jaw member attached to said first end;

a second jaw member attached to said movable seat;

a reinforcing locking member having a threaded hole; and

a bolt passing through one of said side walls to be threaded into said threaded hole and capable of being rotated to assistantly tightly urge one of said side plates against said one side wall.

2. A vise according to claim 1, further comprising a cover fixed to said movable seat and covering thereunder said movable seat, said second end, said guiding screw rods, said active and following gears and said shaft.

3. A vise according to claim 1 wherein said active and following gears are bevel gears.

4. A vise according to claim 1, further comprising another reinforcing locking member having another threaded hole, and another bolt passing through the other said side wall to be threaded into said another threaded hole.

5. A vise according to claim 1 wherein said side plates include therebetween a rib member.

6. A vise according to claim 1 wherein each of said following gears further includes a hollow shaft rotatably mounted in one respective said side hole.

7. A vise according to claim 1 wherein said movable seat includes two upper side blind holes fixedly receiving therein said one ends of said guiding screw rods respectively.

8. A vise according to claim 1 wherein:

said body has one end of said through groove been enlarged in order to put therefrom said lower engaging piece into said through groove;

the wall defining said one groove end includes a pair of opposite protrusions; and

said lower engaging piece has said two side extensions been provided with a pair of opposite indentations respectively capable of passing therethrough said protrusions.

9. A vise according to claim 8 wherein said side extensions are crosssectionally triangular.

10. A vise according to claim 8 wherein said side extensions are crosssectionally rectangular.

11. A vise comprising:

a base having two side walls and a base line for an aligning purpose;

a pivoting medium having a circular angle scale and two lower side plates one of which is provided with an angular scale;

a connecting rod pivotally connecting together said base and said pivoting medium and capable of allowing said side walls to fixedly clamp therebetween said side plates;

an elongate body conditionally rotatably mounted on said pivoting medium and having a first end, a second opposite end having an intermediate hole and side holes, a middlely longitudinal through groove and a second base line capable of being utilized together with said circular angle scale to indicate an angle that said body is rotated with respect to said pivoting medium;

a movable seat having a lower engaging piece which includes two side extensions and is capable of being slidably guided in said groove;

two following gears rotatably untranslatably and horizontally spacedly attached to said second end;

two guiding screw rods respectively passing through said two side holes, screwedly rotatably and respectively coaxially mounted in said following gears and respectively having one ends thereof capable of horizontally spacedly urging against said movable seat;

a shaft rotatably mounted in said second end and passing through said intermediate hole;

an active gear mounted on said shaft and meshed between said following gears;

a driving handle connected to said shaft;

a first jaw member attached to said first end;

a second jaw member attached to said movable seat;

a reinforcing locking member having a threaded hole; and

a bolt passing through one of said side walls to be threaded into said threaded hole and capable of being rotated to assistantly tightly urge one of said side plates against said one side wall.
