SPECIFICATION.

An improved claming device 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 failing down; -a work angle can be adjusted upward and downward with no special limitations.

B: Function: It is used to clamp longitudinal non-para)Iel 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: 40 A: The structural character is that: -it possesses a movable clamping claw 28 and fixed jaw 26, both of them are opposite and posses a spherical concave socket and contain a steel ball 36 in the middle; 45 - due to the pulling join of sprigs 45, 46, it 110 can make universal slide to clamp the work piece. B: Function: It is used to clamp a longitudinal or transverse non-parallel work piece. 50 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; 55 -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 sec- tions, there is an are 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 stab ' i - q - y 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.

13: Function: it is used to clamp irregular shaped work pieces.

C: Defect of the structure is that:

-the terminal clamping claw does not pos sess any direct rigid support surface, and its clamping strength is lower; - -its structure is complicated; -positions of four sets of support points 1 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 in clined surface which couples with fixed jaw 2 and motion jaw 2' and has no limitation struc ture 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 double-dotted lines) B: Function: It is used clamp irregularshaped 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, 13-4); -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 struc- ture of vise which is designed to point exactly 2 GB2171035A 2 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 original 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 posses two sets of movable jaws; -it is constituted by two sets of corresponding clamp jaws wherein on set can swing or move to face face upward; -two pairs of the clamping structure are constituted by two sets of jaws which possess the plate-type clamping claw, wherein one set can swing or move to face upward; -it is constituted by two sets of corresponding clamp jaws wherein ione set pos- sesses the plate-type clamping claw and the other set- possesses two sets of the movable clamping claw, -it is constituted by two sets of corresponding clamp jaws in which one set pos- sesses the plate-type clamping claw and the other set possesses two sets of the movable clamping claw, wherein one jaw can swing or move to face upward; -it possesses other similar functional combinations.

- Above-mentioned combinations and various novel movable clamping claw structure, swinging and facing upward jaw structure, fixing and locking structure of the movable clamping jaw, driving structure, vise base and auxiliary device are combined to constitute the present vise desigh.
