Abstract
The utility model discloses a double-thread labor-saving bench vice, which consists of a fixed jaw fixedly connected with a base and a movable jaw matched with a lead screw. The lead screw consists of a front section and a rear section. The anterior segment matches with movable vice jaw, is connected through the screw thread head and the screw hole of mutually supporting between anterior segment and the back end, and the tip of screw thread head is equipped with the locating piece, and threaded hole is equipped with the set screw with locating piece matched with. A spring is sleeved between the front section and the rear section. The spring rotates in the same direction as the vise clamp. The bench vice can save labor and does not damage workpieces.
Description
Technical field
The utility model relates to a kind of small tool, especially a kind of bench vice.
Background technology
Bench vice be in the small tool a kind of, it be mainly used in clamping work pieces so that processing.Existing bench vice is by forming with fixedly connected regular jaw of base and the moving jaw that matches with leading screw.One end of leading screw is provided with crank, when clamping, rotates crank leading screw is rotated, and the moving jaw that matches with leading screw just moves forward workpiece is clamped.When unclamping workpiece, leading screw is rotated in the opposite direction get final product.Because existing leading screw is the big trapezoidal threaded lead screw of helical pitch, when clamping work pieces, require great effort very much, also easily workpiece clamp is out of shape simultaneously.When unclamping workpiece, require great effort equally very much.
Summary of the invention
Laborsaving when the purpose of this utility model is to provide a kind of use, be difficult for making simultaneously the bench vice of workpiece deformation again
For reaching above-mentioned purpose the utility model bench vice by forming with fixedly connected regular jaw of base and the moving jaw that matches with leading screw.Leading screw is made up of leading portion and back segment.Leading portion matches with moving jaw, is connected with screwed hole by the thread head that cooperatively interacts between leading portion and the back segment, and the end of thread head is provided with locating piece, is provided with the dog screw that matches with locating piece in the screwed hole.Be set with spring between leading portion and the back segment.The direction of rotation of spring is identical with the clamping direction of bench vice.
After adopting said structure, when clamping work pieces,, be set with spring between leading portion and the back segment because leading screw is divided into leading portion and back segment.The direction of rotation of spring is identical with the clamping direction of bench vice.So be provided with the leading portion rotation of the leading screw of handle the moving back segment of springlock taut band is rotated.When clamping work pieces, because resistance has surpassed the coupling mechanism force of spring more greatly, at this moment back segment just can not rotate, thread head that cooperatively interacts and screwed hole between leading portion and the back segment relatively rotate, make the moving jaw of the bench vice clamping work pieces that travels forward, so both laborsaving, can not make workpiece deformation again because of strength is excessive.When unclamping workpiece, rotate the handle of leading portion, thread head that cooperatively interacts and screwed hole between leading portion and the back segment at first relatively rotate, and at this moment workpiece unclamps and need not require great effort.The locating piece of end that relatively rotates to thread head when thread head and screwed hole is when dog screw in the screwed hole matches, and thread head and screwed hole can not relatively rotate, and leading portion just can drive back segment and rotate together.This bench vice has avoided the rotation with the bigger leading screw of pitch to clamp and when unclamping workpiece, though the moving jaw displacement is fast, the shortcoming of effort, but utilize the little threaded engagement of pitch to finish the work both can be laborsaving, again defective work piece not.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1: the utility model bench vice is by forming with fixedly connected regular jaw 10 of base 4 and the moving jaw 1 that matches with leading screw.Leading screw is made up of leading portion 2 and back segment 9.Leading portion 2 matches with moving jaw 1, is connected with screwed hole 7 by the thread head 6 that cooperatively interacts between leading portion 2 and the back segment 9, and the end of thread head 6 is provided with locating piece 11, is provided with the dog screw 8 that matches with locating piece 11 in the screwed hole 7.Be set with spring 5 between leading portion 2 and the back segment 9.The direction of rotation of spring 5 is identical with the clamping direction of bench vice.When clamping work pieces,, be set with spring 5 between leading portion 2 and the back segment 9 because leading screw is divided into leading portion 2 and back 9 sections.The direction of rotation of spring 5 is identical with the clamping direction of bench vice.Make spring 5 lockings drive back segments 9 rotations so be provided with leading portion 2 rotations of the leading screw of handle 3.When clamping work pieces, because resistance has surpassed the coupling mechanism force of spring 5 more greatly, at this moment back segment 9 just can not rotate, thread head that cooperatively interacts 6 and screwed hole 7 between leading portion 2 and the back segment 9 relatively rotate, make the moving jaw 1 of the bench vice clamping work pieces that travels forward, so both laborsaving, can not make workpiece deformation again because of strength is excessive.When unclamping workpiece, rotate the handle 3 of leading portion 2, thread head that cooperatively interacts 6 and screwed hole 7 between leading portion 2 and the back segment 9 at first relatively rotate, and at this moment workpiece unclamps and need not require great effort.When thread head 6 and screwed hole 7 relatively rotate to the locating piece 11 of end of thread head 6 when dog screw 8 in the screwed hole 7 matches, thread head 6 and screwed hole 7 can not relatively rotate, and leading portion 2 just can drive back segment 9 and rotate together moving jaw 1 is unclamped fast.This bench vice has avoided the rotation with the bigger leading screw of pitch to clamp and when unclamping workpiece, though moving jaw 1 displacement is fast, and the shortcoming of effort, rational in infrastructure, easy to use.
Claims (2)
1, a kind of pair of laborsaving bench vice of screw thread, it is by forming with fixedly connected regular jaw of base and the moving jaw that matches with leading screw, it is characterized in that described leading screw is made up of leading portion and back segment, leading portion matches with moving jaw, be connected with screwed hole by the thread head that cooperatively interacts between leading portion and the back segment, the end of thread head is provided with locating piece, is provided with the dog screw that matches with locating piece in the screwed hole, is set with spring between leading portion and the back segment.
2, according to claim 1 pair of laborsaving bench vice of screw thread is characterized in that the direction of rotation of the spring of suit between the leading portion of described leading screw and the back segment is identical with the clamping direction of bench vice.
