HACKSAW WITH HIGH TENSION SAW BLADE

摘要

Built-in sockets in the hacksaw-frame and handle at alternative angles in relation to the blade, constitute the fundamental key-structure of the invention. The resultant achievements in development, now cover the entire region of angles from 90 DEG to 180 DEG in relation with the blade. The socket - Fig. 1 -no. 6 serves as guide-socket for the tension bolt no. 5. The socket - no. 9 serves as guide-socket for the blade-setting bolt - no. 8. It should be noted that the nearer the socket-angle 6 of the tension bolt 5 to 90 DEG - the greater the ease of applying tension to the blade - as opposed to the opposite direction towards 180 DEG . The alternative socket-angles from 90 DEG to 135 DEG have therefore been implimented for tension-mechanism - fig. 1 - (5 and 6). Alternative angles from 136 DEG to 180 DEG have been utilized for blade-setting mechanisms.
