The utility model discloses a saw blade clamping device, including saw blade, reciprocating rod and be used for connecting saw blade and reciprocating rod's clamping
device subassembly, and clamping
device subassembly includes guide, locking sleeve and first elastic part, and the upper end of reciprocating rod is provided with the first locking inclined plane along its periphery extension, and the inner wall of locking sleeve is provided with the second locking inclined plane along its periphery with first locking inclined plane corresponding cooperation, the outer
peripheral wall of reciprocating rod is provided with the limit protruding, and the inner
peripheral wall of locking sleeve is provided with the limit inclined plane with limit protruding corresponding cooperation. Its through clamping
device subassembly realizes the quick installation and disassembly of saw blade, and simple and convenient operation, through the abutting cooperation of limit protruding and limit inclined plane, limit locking sleeve to move down relative to reciprocating rod, through the abutting cooperation of first locking inclined plane and second locking inclined plane, limit locking sleeve to move up relative to reciprocating rod. Further realize the up and down limit of locking sleeve, avoid when not installing saw blade, and locking sleeve shakes relative to reciprocating rod.
