In the slot of pipe sleeve, the groove of bar shaped is formed on the penholder outer wall on rear side of boss, after protecting the rear end of pipe sleeve to be distributed in boss
Side and sleeve are fixed with lasso, and lasso thickens block towards forming on the inner wall of protection pipe set slot-side, thicken grafting on block
It is fixed with acute angle-shaped elastic piece, elastic piece elasticity presses on the bottom surface of penholder groove.
Preferably, the protection pipe covers the coning angle that upper taper protection head cone angle is equal to the connector of penholder front end
The front end face of degree, taper protection head is distributed in the front side of electrode tip.
Preferably, the minimum inner wall aperture that the protection pipe covers upper conical protection head is greater than the maximum gauge of electrode.
Preferably, the width that the protection pipe puts on slot is equal to the spacing between the side wall of boss two sides.
Preferably, the inner diameter of the protection pipe sleeve is equal to the diameter of penholder outer wall.
Preferably, the upper slot of protection pipe set of the penholder upper groove is parallel, and the length of groove is greater than slot bottom surface
To the distance of boss.
The beneficial effects of the present invention are：Its structure is simple, can protect to the working electrode of electric knife, reduces sudden and violent
The working electrode of dew is injured caused by doctor and patient when not in use；It will not influence the replacement of its working electrode simultaneously.
Detailed description of the invention：
Fig. 1 is the three-dimensional structural schematic diagram of the present invention；
Fig. 2 is the partial schematic sectional view of side view of the present invention.
In figure：1, penholder；11, connector；12, boss；13, groove；2, button is cut；3, coagulation button；4, electrode；5, it protects
Protective pipe sleeve；51, taper protects head；52, slot；6, lasso；61, block is thickened；7, elastic piece.
Specific embodiment：
Embodiment：As shown in FIGS. 1 and 2 a kind of telescopic high-frequency electrotome pen, the penholder 1 including high-frequency electrotome pen, penholder 1
Front end form the connector 11 of taper, electrode 4 has been plugged and fixed on connector 11, has been formed on the penholder 1 of 11 rear side of connector convex
Platform 12, cutting button 2 and coagulation button 3 are provided on boss 12, and the front end of penholder 1 is inserted with protection pipe sleeve 5, protects pipe sleeve 5
Front end forms the taper protection head 51 opposite with connector 11 and sleeve is in the front end of electrode 4, the middle and back of the protection pipe sleeve 5
The slot 52 through protection 5 rear end of pipe sleeve is formed, boss 12 is plugged in the slot 52 of protection pipe sleeve, the pen of 12 rear side of boss
