This device, by the principle of operation, resembles ordinary pliers, however, it has a number of certain advantages - here you can easily adjust the degree of clamping of the workpiece, depending on the thickness, and it is also much more convenient to use them when processing small parts.
To make such a manual clamp, you will need a steel strip, a round blank and bolts with nuts. For work, it is necessary to prepare the grinder, electric drill and welding machine. To make a cone-shaped handle, you need a lathe.
The main stages of work
First of all, marking is made on the plate, with the help of a grinder two identical workpieces are cut 12 cm long and 4 cm wide. The resulting workpieces are processed on emery. Then we find the center and drill a through hole in the plates.
At the next stage, on each plate we again make a marking with a caliper and cut off the two upper corners with a grinder. Then again, the details need to be processed on a sharpener to remove burrs. Clamping jaws are welded along the edges of the workpieces, which can be made from pieces of thick metal.
We cut two small segments from a strip 2 cm wide, drill holes at the edges of them, and then connect them to the manufactured parts using bolts and nuts. A stud is welded between narrow plates. Then, on a lathe, a cone-shaped handle is machined and screwed onto a hairpin. Thus, a very convenient manual clip was obtained.
