Description
Technical field
This utility model relates to a kind of medical swing saw, particularly is used for the medical little goose saw mobile phone of osseous tissue cutting in the operation power set.
Background technology
In medical bone surgery, generally adopt goose saw to do the resection operation of osseous tissue by the saw blade of high speed swinging.Medical apparatus requires safe, reliable, easy to operate.Existing medical swing saw, the mode that the installation of saw blade normally adopts nut to compress, installing, change saw blade in operation process needs screw assembling or unscrew by instruments such as wrench to drive down, and not only inconvenient operation, and dismounting speed is slower.Simultaneously, owing in the goose saw work certain vibration is arranged, the situation of nut loosening might appear in the mounting means that adopts nut to compress, and reliability is relatively poor, and can influence operation safety.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of dismounting is convenient, the medical little goose saw mobile phone of good reliability.
The technical solution of the utility model is as follows: a kind of medical little goose saw mobile phone, in main body, be provided with eccentric shaft, its key is: the shift fork clamping mutually of the front end of described eccentric shaft and declutch shift shaft rear end, this declutch shift shaft supports with main body mutually by bearing, the front end of declutch shift shaft stretches in the front end body, and is connected with the front end body by pin; The head end of described front end body has disk body, and at front end body upper sliding sleeve gland is arranged, and this gland pushes against by the disk body of spring and front end body head end.
Adopt above technical scheme, saw blade is clamped between the disk body and gland of front end body, and the running of eccentric shaft drives the declutch shift shaft swing by shift fork, and declutch shift shaft drives the swing of front end body by pin, in the time of the swing of front end body, drives gland and saw blade and swings together.Under the effect of spring, saw blade is pressed between the disk body and gland of front end body all the time, and not only dismounting is convenient, easy operating, and also solid and reliable, even be subjected to the influence of saw blade operational vibration loosening phenomenon also can not occur, safety is secure.
Described shift fork and declutch shift shaft are one, to make things convenient for processing and manufacturing, guarantee structural strength; The little bearing clamping mutually that this shift fork and eccentric shaft front end are installed can effectively prevent wearing and tearing, increases the service life.
For simplified structure, be convenient to quick assembling, the square that upwards wears by the footpath between described front end body and the gland is connected, and the first oblong aperture specific pressure that supplier's piece passes on the front end body to put second oblong aperture that supplier's piece passes long.
Described spring is arranged in the endoporus of front end body, an end of this spring and declutch shift shaft butt, and the other end and limited block butt are formed with cylinder on the described limited block, in the breach on this cylinder embedding square.Spring is arranged in the front end body, dependable performance not only, and can not influence the outward appearance of mobile phone; Limited block cooperates with the square inlay card under the effect of spring, can avoid skidding off the breach of square on front end body and gland, when strengthening the connection fixing, can prevent that gland from rotating relative to the front end body.
In order to make the saw blade clamping more firm, the front end of described gland is formed with the awl dish that adapts with front end body head end disk body.
In order to prevent that saw blade from rotating relative to front end body and gland, be provided with by the equally distributed projection of circumference in the preceding card of described gland awl dish, have the groove that inserts for projection on the back card of described front end body disc body.
Beneficial effect: this utility model just can be realized the clamping of saw blade without instrument, has compact conformation, reliable, characteristics such as dismounting is convenient, and is easy to operate, even and loosening phenomenon can not appear in the influence that is subjected to the saw blade operational vibration yet, effectively improved the safety of operation.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
To shown in Figure 11, medical little goose saw mobile phone has main body 9 and eccentric shaft 10 as Fig. 1, and wherein eccentric shaft 10 is positioned at main body 9, and this eccentric shaft 10 is by bearing and bearing block 11 supportings, and bearing block 11 fixes with main body 9.The rear end of eccentric shaft 10 is connected with motor by drive mechanism, drives eccentric shaft 10 rotations by motor by drive mechanism.Drive mechanism is a prior art, does not do at this and gives unnecessary details.The little bearing 6 of front end suit at eccentric shaft 10, the shift fork 4a clamping mutually that this little bearing 6 is integrally formed with the declutch shift shaft rear end, described declutch shift shaft 4 supports with main body 9 mutually by bearing, the front end of declutch shift shaft 4 stretches in the front end body 1, and be connected with front end body 1 by the pin 5 that radially wears, and the axis of the axis of declutch shift shaft 4 and front end body 1 is on same straight line.
From Fig. 1 to Figure 11 as can be known, head end at front end body 1 is formed with disk body 1a, and gland 2 is arranged at front end body 1 upper sliding sleeve, the square 3 that upwards wears by the footpath between front end body 1 and the gland 2 is connected, and the first oblong aperture 1b that supplier's piece 3 passes on the front end body 1 grows than the second oblong aperture 2b that supplier's piece 3 on the gland 2 passes.Spring 7 and disc limited block 8 also are housed in the endoporus of front end body 1, the front end face butt of the rear end of its medi-spring 7 and declutch shift shaft 4, the back card of the front end of spring 4 and limited block 8 connects.The center of card is formed with cylinder 8a before limited block 8, in the breach 3a on this cylinder 8a embedding square 3, skids off to prevent square 3.Front end at described gland 2 is formed with the awl dish 2a that adapts with front end body head end disk body 1a, and the preceding card of this awl dish 2a is provided with by the equally distributed projection 2c of circumference, has the groove 1c that inserts for projection 2c on the back card of described front end body disc body 1a.Under the effect of spring 7, the disk body 1a of the awl dish 2a of described gland 2 and front end body head end pushes against.
Adopt said structure, saw blade is sleeved on the gland 2, and between the disk body 1a of the awl dish 2a of gland 2 and front end body, the projection 2c on the awl dish 2a passes the via hole on the saw blade and inserts among the groove 1c of disk body 1a, rotates relative to front end body 1 and gland 2 to prevent saw blade.The running of eccentric shaft 10 drives declutch shift shaft 4 by shift fork 4a and swings, and declutch shift shaft 4 drives 1 swing of front end bodies by pin 5, in the time of 1 swing of front end body, swings together by square 3 drive glands 2 and saw blade.When pulling back gland 2 as shown in Figure 1, square 3 can slide in the first oblong aperture 1b, and spring 7 is compressed, and the awl dish 2a of gland 2 leaves the disk body 1a of front end body, can unclamp the clamping to saw blade.
