Detailed Description

In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.

The invention is explained in further detail with reference to the drawings, in which the reference symbols are: 1: a housing; 2: a cylinder; 3: a first rotating shaft; 4: a second rotating shaft; 5: a first clamping jaw; 6: a second clamping jaw; 7: a first tail handle; 8: a tail handle II; 9: a first crank; 10: a crank II; 11: a U-shaped connector; 12: a cylinder rod; 13: a guide rail; 14: a slider; 15: a drive shaft; 16: a long hole; 17: a bar workpiece.

The directions defined in this application are as follows: in FIG. 1, the bar is at the front and the cylinder is at the back; the bar stock is in the up-and-down direction. The above orientation definitions are for better explanation of the present application and do not represent installation and use orientations in actual production.

As shown in the attached drawings, the rotary bar clamp comprises a shell 1, wherein two rotating shafts distributed in the left and right directions are rotatably connected to the shell, and the two rotating shafts are a first rotating shaft 3 and a second rotating shaft 4; the clamping jaw mechanism comprises a clamping jaw, a clamping jaw I5, a clamping jaw II 6, a rotating shaft II 4, a crank I9, a crank II 10, a crank II 4 and two tail handles, wherein the clamping jaw I is fixedly connected to the rotating shaft I3, the crank II 9 is fixedly connected to the rotating shaft II 4, the two cranks are vertically distributed, two tail handles are arranged at the back of each clamping jaw, the tail handle I7 is arranged at the back end of the clamping jaw I, the tail handle II 8 is arranged at the back end of the clamping jaw II, and the back ends of the two tail handles are fixedly connected to the upper portion and the lower portion of a driving shaft on the corresponding side respectively.
