The utility model provides a following technical scheme is:

a portable bench clamp is composed of four parts, namely a base, a movable jaw, a screw rod and a fixing screw, wherein the base comprises a guide rail, a screw hole and a mounting hole. Greatly simplifying the structure of the bench clamp.

Moreover, the guide rail and the base are integrally designed, and the base is provided with four pillars for supporting the concave guide rail.

And the screw hole is positioned on the base, so that the screw rod is convenient to mount, and the screw rod and the base are integrally designed.

And when the workpiece is clamped, the workpiece is placed on the concave guide rail but is not contacted with the guide surface of the guide rail, so that the abrasion of the workpiece to the guide surface is avoided, and the precision and the service life of the bench clamp can be well protected.

In addition, the movable jaw is integrally designed, so that the installation of the bench clamp is simplified, and the stability is improved.

Moreover, two sliding blocks are arranged at the bottom of the movable jaw and are used for matching with the guide rail to move, and the movable jaw is positioned.

And the screw hole is arranged at the head of the screw rod, so that the movable jaw and the screw rod are convenient to fix, the arrangement that the conventional screw rod penetrates through the whole base is changed, the position of the screw rod is lifted to the upper side of the base, and the bench clamp is convenient to install.

Moreover, the fixed clamp body is integrally designed, so that the installation of the bench clamp is facilitated, and the weight of the fixed clamp body is reduced.

Moreover, the base is integrally designed, so that the number of parts is greatly reduced.

The beneficial effects of the utility model are that, carried out a large amount of integrated designs to the bench vice structure, made things convenient for the installation, the dismantlement, the removal of bench vice, the part quantity that has significantly reduced to the operation of having simplified the bench vice makes easy operation.

The present invention will be described in further detail with reference to the drawings and specific examples.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings, and the following embodiments are illustrative only, not limiting, and should not be construed as limiting the scope of the present invention.

In order to describe the present invention in detail, first, the bench clamp of the present invention will be described specifically.

The core of the utility model is to provide a portable bench vice, which changes the prior base 1 structure, screw 6 structure and arrangement mode, and movable jaw 4 structure. The bench clamp base comprises a fixed jaw 9, a concave guide rail 3, a screw hole 7 and a mounting hole 10. The concave guide rail 3 is placed on the base through four support columns, the guide surface of the concave guide rail 3 is used for being matched with the sliding block at the bottom of the movable jaw 4 to work, and a workpiece is placed on the upper surface of the concave guide rail 3, so that even if the concave guide rail 3 is abraded or deformed in the using process, the sliding fit between the movable jaw 4 and the guide rail 3 is not influenced, and further the working precision and the service life of the bench clamp are improved. Screw holes 7 are also arranged on the base for positioning the screw rods 6 and providing clamping force for the screw rods 6, mounting holes 10 are used for mounting bench clamps, and the fixed jaw 9 is used for matching with the movable jaw 4 to clamp parts. The arrangement of the screw 6 is changed from the prior structure of crossing the base into the arrangement of directly matching with the screw hole of the base and the movable jaw 4, and the top of the screw 6 is provided with a screw hole for matching with a fixed screw 8 to fix the movable jaw.
