The specific embodiment
Referring to Fig. 1 to Figure 14, a kind of medical chest bone saw mobile phone described in the utility model, comprise that the bearing block 30 that is located by connecting on handle tube 29 upper ends, an end are engaged in the handle tube by the bearing location and the other end cooperates with the bearing block location and the eccentric shaft 1 of projecting shaft bearing, be located by connecting on bearing block both sides and the driving lever 3 that is connected with reciprocating shaft 5 by driving lever pin 4 with the vertical stack shell 13 of handle tube, the capacity eccentric bearing 2 that is located at the eccentric shaft upper end, right-hand member and capacity eccentric bearing cooperation and left end, be threaded with the reciprocating shaft left end compress spin nut 8; The left end of reciprocating shaft 5 is provided with a seam 16 along axial line, is provided with an annular groove 17 at the direction middle part perpendicular to this seam, and the right of annular groove is provided with dog chart sheet positioning chamber 18 and reed dowel hole 20, and the right-hand member of reciprocating shaft is provided with a circular hole 24;
One end of one dog chart sheet 9 inserts in the square hole 27 of saw blade pin 10, the saw blade pin inserts in the circular hole 28 of saw blade 19 right-hand members, reed alignment pin 15 inserts in the arcuate socket and the reed dowel hole 20 on the reciprocating shaft 5 of dog chart sheets 9 right-hand members, thereby the dog chart sheet is positioned in the dog chart sheet positioning chamber 18 on the reciprocating shaft;
One connector, 7 left ends by screw thread with protect sheath 11 and be connected, the connector right-hand member is connected with attaching nut 6 by screw thread, three steel balls 12 are loaded on respectively along in three spherical pores 21 of connector 7 circumference uniform distributions; Align with the left surface of stack shell right part boss in the right side of connector 7, one protects sheath alignment pin 14 inserts with hole on the stack shell 13 from the breach 31 of connector and cooperate; The circular hole 26 of driving lever 3 left parts is connected by the circular hole 24 of driving lever pin 4 and reciprocating shaft 5 right-hand members, and the positioning chamber 25 of driving lever right-hand member is by being connected with capacity eccentric bearing 2 and eccentric shaft 1.
Saw blade mounting or dismounting step is: unscrew earlier and compress spin nut, saw blade pin bullet under the elastic force effect of dog chart sheet forms the slit from the reciprocating shaft median plane, and saw blade is inserted into the bottom locating surface along the slit, screw spin nut again; Thereby the saw blade pin overcomes the elastic force of dog chart sheet under the pressure effect that compresses the spin nut conical surface enters locking saw blade in the saw blade circular hole, unscrews when pulling down saw blade and compresses the spin nut taking-up.
Protecting sheath parts installation steps is: protect sheath and connector by thread connection and beat thread locking adhesive and fix, be pressed into the attaching nut and screw screw thread after putting into steel ball in 3 spherical pores on the connector circumference, protect the installation of sheath parts.
Protecting the sheath parts stack shell step of packing into is: unscrew the attaching nut earlier, the spherical pore of steel ball on the connector circumference enters in attaching nut's the cannelure 23, breach on the connector 31 is aimed at close-fittings on stack shell, protect the left surface that sheath alignment pin 14 pushes stack shell right part boss, screw nut again, thereby steel ball enters in the spherical pore on the connector and enters in the cannelure 22 on the stack shell and is locked on the stack shell from attaching nut's cannelure.Unscrewing attaching nut's taking-up when pulling down gets final product.
The elongated rod-shaped structure of protecting sheath can protect that to implement operator unlikely injured, also can guarantee that bone that saw blade is not cut clamps simultaneously and influence fortune association is smooth and easy.The hook formation that protects the sheath left end can catch on the breastbone bottom in the process of saw, thereby guarantees that saw blade is unlikely damage chest soft tissue.Protect upper and lower symmetry on the sheath parts connector and drive locating slot and help protecting 0 ° and 180 ° of two positions assemblings on stack shell of sheath parts, thus help described chest bone saw forwards, backwards both direction implement sawing.
