First steel ball and connecting portion are against installation, so be may be implemented in when turning cutter and screwing switch, cutter screw switch relative to
Connector is rotated, and rotary switch and connector are constantly in relatively because of the effect of the first spring and the first steel ball
Firm state.
The cutter fixed cover has for the nested hole of the second steel ball.
In the tool lock system, the cutter axis of guide clamps cutter by cutter fixed cover and the second steel ball.
When installing cutter, turn cutter and screw switch, cutter screws switch with the second steel in cutter fixed cover hole
Pearl rotates, and then is moved with cutter fixed cover, and the inclined-plane of the inclined-plane squeezing knife tool axis of guide inside cutter fixed cover forces knife
Has axis of guide clamp-on tool.The tool lock system is simple in construction, cutter convenient disassembly.
During using the reciprocating saw, the power of driving shaft transmission drives arc drive bevel gear, and arc driven wheel of differential passes through
Engagement passes motion to arc driven wheel of differential, so as to drive eccentric shaft while carry out coaxial rotating motion, is enclosed on eccentric shaft
On swing rod, moved together by the straight pin band cutter axis of guide, eccentric shaft moves a circumference, cutter carry out one it is reciprocal
Back and forth, cut so as to complete the high-speed smooth in bone tissue resection operation.
Beneficial effects of the present invention：
Medical reciprocating saw provided by the invention, its guiding mechanism load is small, and can realize high-precision easy motion, cutter
Locking mechanism structure is simple, and cost is low, cutter convenient disassembly.
