[specific embodiment]

Can explain in more detail the present invention by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;

1～2 described Multifunctional bench clamp by reference to the accompanying drawings, described bench vice comprises base 1, leading screw 4 and active clamp block 5; Described base 1 is a rectangular panel blocks, be respectively equipped with an outstanding locating piece 2 in the termination of plate upper side two long ends, this locating piece 2 can be made as integrative-structure with base 1, or locating piece 2 and base 1 are fixed together by snap fit, again or by bolt locating piece 2 is fixedly connected on base 1, simultaneously, the plate body of rectangular panel blocks between two ends locating piece 2 that consists of base 1 has two at least has spacing and parallel groove 3, the interior rhizoid thick stick 4 that all is mounted with of each groove 3; Have influence on the regular event of leading screw 4 in the groove 3 for avoiding foreign material to drop, the bottom of groove 3 can be made as uncovered, thereby be more convenient for cleaning and leading screw 4 is installed; Described leading screw 4 is trapezoidal screw, thereby can utilize the auto-lock function of trapezoidal screw to reach the purpose that active clamp block 5 is accurately located;

for ease of installation and removal, the two ends of leading screw 4 can be bolted to connection the position in base 1 correspondence, for reaching the purpose of increasing work efficiency, can connect at least two active clamp block 5 on each rhizoid thick stick 4, be that the bottom of each active clamp block 5 all is positioned at corresponding groove 3 and is connected with leading screw 4, and each active clamp block 5 all can move or fix along corresponding leading screw 4 between the locating piece 2 at base 1 two ends, simultaneously, the conflict that all can coincide of corresponding surface between corresponding surface between two active clamp block 5 and active clamp block 5 locating piece 2 corresponding with it, thereby the active clamp block that two locating pieces 2 that make base 1 two ends can be adjacent respectively 5 forms the clamping jaw of an activity, and also can form the clamping jaw of an activity between every two active clamp block 5, this just makes active clamp block 5 on each rhizoid thick stick 4 all can form the clamping jaw of at least three activities, and then practicality and the operating efficiency of bench vice have effectively been increased,

3～4 described Multifunctional bench clamps by reference to the accompanying drawings, described active clamp block 5 comprises grip block 6, power transmission shaft 7, sleeve 8 and spiral bevel gear; Described grip block 6 middle parts are provided with for coincideing and lay the upright opening 9 of power transmission shaft 7, and the upper end of power transmission shaft 7 is drive end, and the termination, lower end of power transmission shaft 7 connects the first spiral bevel gear 10 by key 15 after running through upright opening 9; The bottom faces both sides of grip block 6 are respectively equipped with an outstanding pin 11 downwards, and two pins 11 of these both sides can corresponding be placed in same groove 3 on base 1, and namely each grip block 6 all can be placed in corresponding groove 3 by pin 11 cards; More steady for what active clamp block 5 was moved, can link together by the bottom faces of a contiguous block 14 with 6 two pins 11 of same grip block; For grip block 6 can be moved along leading screw 4, can with the corresponding horizontal center that is hinged on 6 liang of pins 11 of grip block of 4 sleeves that connect of leading screw, 8 two ends outer walls, two pin 11 correspondences that are grip block 6 are enclosed within on the outer wall at sleeve 8 two ends, in addition, because the position in sleeve 8 outer walls corresponding two pin 11 inboards connects a spacing interlock ring 12 by key 15 respectively, therefore, when moving along leading screw 3, the spacing interlock ring 12 on sleeve 8 outer walls can drive grip block 6 synchronizing movings when sleeve 8;

for ease of installing/dismounting, described spacing interlock ring 12 is made of the semicircular ring that is bolted two symmetries together, in addition, because the stack shell outer wall of described sleeve 8 between two spacing interlock rings 12 connects the second spiral bevel gear 13 by key 15, and the second spiral bevel gear 13 and the first corresponding engagement of spiral bevel gear 10, therefore, when the upper end of rotating drive shaft 7, power transmission shaft 7 has also driven the second spiral bevel gear 13 and has rotated when driving the first spiral bevel gear 10 rotations, and the second spiral bevel gear 13 has driven sleeve 8 rotations when rotating, when sleeve 8 rotates, related grip block 6 is made corresponding movement along leading screw 4, thereby reached by rotating drive shaft 7 and driven the purpose that active clamp block 5 moves, for simplifying fitting operation, spacing interlock ring 12 and second spiral bevel gear 13 of sleeve 8 outer walls corresponding pin 11 inboards can be made as integrative-structure, rotate thereby make the second spiral bevel gear 13 namely can drive sleeve 8, can also drive grip block 6 with sleeve 8 synchronizing movings simultaneously.

When implementing the conventional workpiece of Multifunctional bench clamp processing described in the utility model, only need to adjust the active clamp block 5 on every rhizoid thick stick 4, make it form a plurality of clamping jaws and namely can reach the purpose of a plurality of workpiece of clamping simultaneously; When the processing profiled workpiece of needs, also only need to be according to the Adjusting Shape of special-shaped workpiece active clamp block 5 positions on corresponding leading screw 4, finally jointly the special-shaped workpiece firm grip is got final product by a plurality of active clamp block 5, an end of active clamp block 5 holding workpieces on a rhizoid thick stick 4 for example, the other end of active clamp block 5 holding workpieces on another rhizoid thick stick 4, or described bench vice is erected, can more efficiently clamping associated workpiece.

The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
