摘要

A hacksaw with an improved mechanism for adjusting the tension on the blade. The mechanism includes a lever for vertically moving a rod to pivot a rocker arm to place tension on the rocker arm-held blade. The rod has an adjustment knob at its lower end to precisely select final blade tension. The lever has a latch means for securely locking the lever closed, and the latch means has a safety feature which prevents accidental and sudden unlocking of the lever.
