Specific embodiment

The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-5:

A kind of Electric scalpel, including knife handle 1 and the electric knife head 5 for being fixed on 1 front end of knife handle, 1 side wall of the knife handle is equipped with recessed Hole 3, pit 3 is interior to be equipped with operation button 4；Sliding is arranged with protective jacket 2 on knife handle 1, and axial slide 6, sliding slot are offered on knife handle 1 6 are located at 3 rear of pit, and sliding slot 6 is connected to 1 inner cavity of knife handle, and 2 inner wall of protective jacket is connected with sliding block 8, and sliding block 8 protrudes into knife handle by sliding slot 6 1 inner cavity is simultaneously connected with drive rod 10, and drive rod 10 extends towards 1 front end of knife handle and is connected with electric knife set 7, electric knife set 7 on head Sliding is set on electric knife head 5, the annular opening 18 that there is 1 front end of knife handle power supply broach shell 7 to stretch out；10 tail portion of drive rod is connected with Compressed spring 9；1 side wall of knife handle is equipped with mounting groove 12, and limited block 15 is combined in mounting groove 12, and limited block 15 is limited in mounting groove In 12 and head can pass through 12 mouthfuls of stretching 1 side walls of knife handle of mounting groove；Radial spring 14 is equipped between limited block 15 and mounting groove 12, 15 outer end face of limited block is the inclined surface towards 5 direction of electric knife head.

So set, when need to use, protective jacket 2 pushes backward, so that the operation button 4 in pit 3 exposes, protection Set 2, so that electric knife set 7 acts backward together, exposes electric knife head 5 by driving the synchronization of drive rod 10 to move backward；Protective jacket 2 is got over It crosses after limited block 15,15 head of limited block is stretched out under the effect of radial spring 14, to block protective jacket 2, while drive rod The compressed spring 9 of 10 tail portions is again to force is played, so that protective jacket 2 is pushed against on limited block 15；When storing electric knife, pass through pressing Limited block 15, limited block 15 overcome 14 active force of radial spring to inside contract, and protective jacket 2 loses limit, the court under the effect of compressed spring 9 It is mobile to 5 direction of electric knife head, and drive electric knife set 7 to move together by drive rod 10, it only is against 6 front end of sliding slot to sliding block 8, Anti-slip cover covers pit 3 at this time, and electric knife set 7 entangles electric knife head 5, to realize effective protection, avoids maloperation and dust is thin Pollution of the bacterium to electric knife head 5.

In conjunction with Fig. 3 and Fig. 4, the mounting groove 12 is made of the support 13 to arch upward towards 1 inner cavity of knife handle, and support 13 supports institute State drive rod 10.13 inner surface of support can be used to support drive rod 10, guarantee the operation stability of drive rod 10, while appearance Face may be constructed mounting groove 12 again, realize that space rationally utilizes.

Wherein, 8 rear end of sliding block is connected with protective cover plate 16, and protective cover plate 16 is fitted on 1 internal chamber wall of knife handle. Protective cover plate 16 can cover sliding slot 6 when protective jacket 2 covers pit 3, and dust is avoided to enter intracavity of handle.

1 cross section of knife handle is ellipse combined with Figure 1 and Figure 2, and 2 cross section of inboard wall of protective jacket is ellipse.It is ellipse Circular configuration can limit protective jacket 2 and circumferentially rotate, and cooperate closer.

Specifically see Fig. 5,1 front end of knife handle is equipped with the screw thread mouth 17 concentric with annular opening 18, and the electric knife head 5 is waist Shape, the annular opening 18 are kidney-shaped, and the screw thread mouth 17 is greater than the outer diameter of electric knife head 5 and is less than the outer diameter of annular opening 18. Screw thread mouth 17 can be spirally connected the screw 11 of inner hollow, block 7 Forward of electric knife set by screw 11, cooperate with limited block 15, rise To double protection, avoid in surgical procedure accidentally by limited block 15.
