Description

Multifunctional wrench

The utility model relates to a kind of hand tools of industrial use, especially a kind of improvement of monkey wrench.

Existing monkey wrench comprises handle, movable head, fixing head, promotes the movable head motion by worm screw, can not clamping work pieces, and function singleness.

The purpose of this utility model provides a kind of monkey wrench of energy clamping work pieces, can realize multiple function.

The utility model comprises handle, fixing head, movable head and the worm screw that can promote movable head, difference is that fixing head and movable head are provided with one can the cephalomotor screw rod of pulling activity, screw rod and worm screw axially parallel, the clamping face in opposite directions of fixing head and movable head is provided with two mutually perpendicular V-shaped grooves.

Movable head and fixing head are provided with fixing hole in the such scheme.

The utility model is except that the function with normal activity spanner, and rotating screw bolt can clamp small workpiece, and V-shaped groove can help fixation workpiece.If the clamping saw blade can replace saw bow to use.

Fig. 2 is the utility model vertical view.

Fig. 3 is Fig. 2 A-A cutaway view.

Fig. 4 is Figure 1B-B cutaway view.

Fig. 5 is 1 place's enlarged drawing of Fig. 3.

Originally draw together wrench and comprise handle 5, fixing 1, movable head 2 and worm screw 3, screw rod 7 passes fixing head and movable head, this screw rod and movable head pass through thread connection, and establish catch in the fixing head outside, can spur the movable head motion, on fixing head and the movable head face in opposite directions, be provided with two mutually perpendicular V-shaped grooves 8, movable head and fixing head are provided with among fixing hole 9, the figure 6 and are the anchorage bar to the screw rod reinforcing, and 4 is the worm screw trip bolt.

It is exactly the normal activity spanner that the utility model is not loaded onto screw rod, needs to do to clamp when being used for clamping work pieces, and dismounting trip bolt 4 takes off worm screw 3, loads onto screw rod 7, rotates anchorage bar, gets final product clamping work pieces.As mainly making spanner usefulness, the interim work do not dismantled worm screw the pincers time spent, and rotary worm is clamped work gently during use, rotates anchorage bar again workpiece is clamped.When loosening, earlier loosening anchorage bar, little more loosening worm screw, workpiece can become flexible.Fixing hole 9 can be used to install various jaws, prevents to crush workpiece.

Claims (2)

1, a kind of multifunctional wrench, comprise handle, fixing head, movable head and the worm screw that can promote movable head, it is characterized in that fixing head and movable head are provided with one can the cephalomotor screw rod of pulling activity, screw rod and worm screw axially parallel, the clamping face in opposite directions of fixing head and movable head is provided with two mutually perpendicular V-shaped grooves.
