Design

Evaluation 3 of 5

Automatic claw hammer - head screwdriver to consists of a body and a wedge. The housing is a small segment of the small diameter pipe having a cut out portion of the wall.

By the end of the housing is welded washer. Wedge made the author of a small area and then welded to the spindle nut. Next to the body is inserted into the threaded rod, and it is screwed nut is a wedge. The free end of the rod is fixed in the screwdriver.

The design of this product seemed to me cumbersome. Pull out the nails of the nozzle can be only if the head protrudes slightly.

To pick up the head of a nail, claw tilt from side to side will not work: will interfere with the body. Therefore, the author receives only 3 points.
