BACKGROUND OF THE INVENTION:

The present invention has made reference to the following information of the published and granted patents:

U.S. Patent Nos. 113, 656, 4, 240, 621, 171, 868 French Patent No. 471, 674
Australian patent No. 174, 872

1. Analysis on U.S. Patent No. 113, 656:

A: Structural character is that

-a transverse back arc clamping claw is placed from the front side to couple with the jaw which possesses an arc slot;
-an arc slot of clamping sheet at two sides is coupled with a pin at two sides of the jaw in order to avoid of the work piece the falling down;
-a work angle can be adjusted upward and downward with no special limitations.

B: Function: lt is used to clamp longitudinal non-parallel work piece.
C: Defect of the structure is that:

-the method of placing a work piece from front side must assemble clamping sheets h andh' and pins at two sides, therefore, it needs many parts, and easity loosens and increases the ineffective space, the fragile parts are exposed outside to be -collided and out of work;
-there is no design for limiting the upward facing angle, and when the clamp length of the clamping piece is shorter than radius H, it can not tightly clamp the work piece as shown in Figs. A-1, A-2.

2. Analysis on U.S. Patent No. 4, 240, 621:

A: The structural character is that:

-it possesses a movable clamping claw 28 and fixed jaw 26, both of them are opposite and possess a spherical concave socket and contain a steel ball 36 in the middle;
-due to the pulling join of springs 45, 46, it can make universal slide to clamp the work piece.

B: Function: It is used to clamp a longitudinal or transverse non-parallel work piece.
C: Defect of the structure is that

-it only submits the design of the single set clamp, therefore it can not pay attention to the auxiliary structure of sliding work piece away when the inclination angle is too long;
-there is no design of the multi-angular clamp for irregular-shaped work pieces.

3. Analysis on U.S. Patent No. 171, 868:

A: Structural character is that

-it possesses a two-sectional fixed jaw, wherein its one section near the clamp surface can make angular slides;
-one section near the clamp surface possesses an arc slot which joins with a pin on the fixed section, and between said two sections, there is an arc coupling surface.

B: Function; It is used to clamp the transverse non-parallel work pieces.
C: Defect of structure is that:

-The two-sectional structure can make the body of the vise become longer;
-two jaws the motion bodies which will affect the stability of itself after clamping.

4. Analysis for French Patent No. 471, 674:

A: Structural character is that:

-it possesses the multi-set of the twing-type Y-shaped arm;
-each branch joint possesses a movable pin.

B: Function: it is used to clamp irregular-shaped work pieces.
C: Defect of the structure is that:

-the terminal clamping claw does not possess any direct rigid support surface, and its clamping strength is lower;
-its structure is complicated;
-positions of four sets of support points 11 are constant, and its application on clamping irregular-shaped work pieces is limited.

5. Analysis on Australian Patent No. 174, 872:

A: Structural character is that:

-it possesses four sets of movable clamping claws 5 which join with arc movable jaw 4 by pin 6;
-distance between the clamping surface of movable clamping claw 5 and pin 6 is larger than radius of circular arc surface which is joined by blocks 5 and 4;
-arc-type movable jaw 4 possesses on inclined surface which couples with fixed jaw 2 and motion jaw 2' and has no limitation structure and can be taken down freely.
-as shown in Fig. 2, joint arc surfaces of movable clamping jaws 5 and 4 do not directly contact each other (as shown in the drawing by doubledotted lines)

B: Function: It is used to clamp irregular-shaped work piece.
C: Defect of the structure is that

-distance between the clamping surface of clamping claw 5 and pin 6 is larger than the radisus of the circular arc, the range which is suitable for work pieces is limited (as shown in Figs. B-1, B-2, B-3, B-4);
-arc-type movable jaw 4 has not been fixed yet, and will fall down from the front side (as shown in Fig. C-1);
-it possesses plural safety points (as shown in Figs. D-1, D-2, D-3) which will cause the balance of the working table unstable and make troubles when milling processing is mass-produced (as shown in Figs. D-4, D-4-1, D-5, D-5-1);
-movable clamping claws 5 and 4 are joined by pin 6, and the circular arc surface does not rigidly couple with claw 4, therefore, the clamping force is limited.

Therefore, the present invention is a structure of vise which is designed to point exactly against the above defects: it is characterized in that:

-at least one of the two sets of corresponding clamp jaws possesses stabley transverse directrix;
-Stably transverse directrix includes the line which is constituted by line of claw surface of plate-type clamping claw used for fixing position; or at least two sets of movable clamp jaws which have a metacentre respectively.

Therefore, the present invention can solve the problems and defects of the above each of the cited references and keep the orginal merits and posses further merits, and summing up the above characters, its combination includes the following types:

-it is constituted by two sets of corresponding clamp jaws which respectively possess two sets of movable jaws;

DETAILED DESCRIPTION OF THE INVENTION

The vice of Figure 1 has the following features:

1. The inner concave dove tail arc slot is installed on the back side of the half-circular clamping jaw and a limiting pin rod is installed at two ends of the said dove tail arc slot. Moreover:
- a) Screws coupled with the dove tail arc slot, and
- b) Screws and dove tail block penetrating through the back side of the jowl are installed on the back arc of the jowl.
2. There is no support seat on the bottom side of the moving jowl, thus the movable clamping jaw can directly slide on the guide track of the machine seat to increase the suitability for clamping the working piece.
3. The height of the bottom side of the movable clamping jaw of the fixing jowl is same as which of the sliding track on the machine seat.
4. The inner concave arc face between two arc slots on the jowl extend downwards through the bottom for penetrating the working piece.
5. The outer side of the jowl contracts toward the inside, thus the sliding motion of the clamping jaw can't be stopped, when it clamps the working piece with the concave shape on the middle section.

Fig. 2 is a perspective graphic view of the clamping claw 1001 as shown in Fig. 1, its front side is a plane, and two sides are reversed triangular and therefore, it forms a three-side clamping surface, its merit is alert and suitable for various shapes of the clamped pieces;
