In use, referring to fig. 6-10, the base 8 of the present invention is inserted into the fixing slot 83 of the fixing lug 82 at the bottom of the base 8 by the fixing screw B and screwed on the working table C (as shown in fig. 9 and 10), when an object a is to be clamped, only the holding rod 74 on the main screw 7 is held to rotate (as shown in fig. 7 and 8), the main screw 7 is screwed inwards by the external thread 70 to push the movable chuck 3 and the clamping chuck 5 towards the fixed chuck 21, when the clamping chuck 5 is contacted with the object a (as shown in fig. 8), the positioning nut 75 on the main screw 7 is firstly screwed to abut against the outer wall surface of the fixing base 2 to be positioned, so that the main screw 7 is not screwed, then the pulling rod 42 on the eccentric shaft 4 is pressed downwards (as shown in fig. 9), the pulling rod 42 drives the eccentric shaft 4 to rotate, so that the eccentric portion 40 of the eccentric shaft 4 eccentrically rotates and the boss 50 of the clamping chuck 5 slightly pushes outwards, the clamping chuck 5 is moved to the direction of the fixed chuck 21, and further the clamping chuck is clamped on the object A, so as to tightly clamp the object A, thus, when clamping the object A, only the pull rod 42 is needed to be pulled downwards, the eccentric part 40 is pushed against the clamping chuck 5 to finely adjust and move towards the fixed chuck 21, and the object A can be stably and tightly clamped, the object A is very convenient and fast to clamp, and the movable chuck 3 and the clamping chuck 5 of the invention are provided with the slide blocks 39 and 53 and the positioning plates 60 and 61, can be stably positioned in the slide groove 22 and the guide groove 23 of the fixed seat 2 to slide, so that the object A is very stable when moving and clamping the object, and the worry of shaking, deviation or falling-off is avoided.

The base 8 can be detached from the vice, the screw elements 28 on the positioning lugs 26 of the fixing base 2 are directly locked on the workbench, the vice can be horizontally arranged, and the base 8 is used for vertically arranging the vice, so that the vice can be conveniently constructed and operated for different processing requirements.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
