Abstract
The present invention proposes a kind of jaw face shell pen type goose saw structure, including housing, motor, pendulum according to head main shaft, bearing, knife rest, saw blade and shift fork, motor is arranged in housing, pendulum is arranged on the rotor portion of motor according to head spindle eccentricity, knife rest is by bearing connection pendulum according to head main shaft, and the axial line perpendicular to pendulum according to head main shaft, saw blade is fixedly installed on knife rest, shift fork is coaxially fixedly installed on knife rest, the end of shift fork has groove, bearing is at least partly located in groove, the outer ring of bearing and the side of sidewall portion phase movable contact of groove.Motor driving pendulum is according to head main axis, because shift fork and pendulum are provided with bearing according between head main shaft so that shift fork is with putting one end reciprocally swinging contacted according to head main shaft, so that shift fork band movable knife rack and saw blade reciprocally swinging.Because shift fork is connected the CONTACT WITH FRICTION that can be avoided between swinging head main shaft and shift fork with knife rest, there is the advantages of intensity big stable drive, improve transmission efficiency and service life.
Description
Technical field
The invention belongs to technical field of medical instruments, specifically, more particularly to a kind of jaw face shell pen type goose saw structure.
Background technology
At present, in decorative sursery clinical operation, not yet special equipment at present, the conventional medical bone drill or micro- of generally use
Type power saws are bored, and these medicine equipments are not special for decorative sursery, therefore during use, cutting mouth is excessive, both causes
Doctor's waste of time, also result in the unnecessary pain of patient, especially child patient more very.
In bone surgery, it is often necessary to cut off the bone tissue to break down of patient with saw, in cutting, in order to avoid suffering from
Person bleeds excessively, and the wound of cut place is the smaller the better, and this requires medical swing saw to need the high speed swinging in less stroke to cut
Cut.Medical swing saw in currently available technology, without the special goose saw of decorative sursery.
The content of the invention
It is an object of the invention to provide a kind of jaw face shell pen type goose saw structure, have that simple in construction, cutting wound is small
And the advantages that convenient use.
To achieve these goals, the present invention proposes a kind of jaw face shell pen type goose saw structure, including：Housing, motor,
Put according to head main shaft, bearing, knife rest, saw blade and shift fork, wherein, the motor is arranged in the housing, and the pendulum is according to head main shaft
It is eccentrically arranged on the rotor portion of the motor, the knife rest connects the pendulum according to head main shaft by the bearing, and
Axial line perpendicular to the pendulum according to head main shaft, the saw blade are fixedly installed on the knife rest, and coaxially fixation is set the shift fork
Put on the knife rest, the end of the shift fork has groove, and the bearing is at least partly located in the groove, the axle
The outer ring held and the side of sidewall portion phase movable contact of the groove.
Further, in described jaw face shell pen type goose saw structure, the both ends of the bearing are consolidated by jump ring respectively
It is scheduled in the groove and pendulum is according on head main shaft.
Further, in described jaw face shell pen type goose saw structure, the inner ring of the bearing is fixed on the pendulum evidence
On head main shaft, the outer ring of the bearing and the side of sidewall portion phase movable contact of described groove.
Further, in described jaw face shell pen type goose saw structure, the shift fork and the knife rest are integrally formed.
Compared with prior art, the beneficial effects are mainly as follows：Motor driving is put according to head main axis, due to
Shift fork and pendulum are provided with bearing according between head main shaft so that one end reciprocally swinging that shift fork contacts with pendulum according to head main shaft, so that
Shift fork band movable knife rack and saw blade reciprocally swinging.Because shift fork is connected with knife rest, it is set to avoid between swinging head main shaft and shift fork
CONTACT WITH FRICTION so that the present invention has the advantages of intensity big stable drive, not only increases transmission efficiency, also improves using the longevity
Life.
Brief description of the drawings

Realize the advantageous effects of the present invention.Therefore, description below is appreciated that for the widely known of those skilled in the art, and
It is not intended as limitation of the present invention.
For clarity, whole features of practical embodiments are not described.In the following description, it is not described in detail known function
And structure, because they can make the present invention chaotic due to unnecessary details.It will be understood that opening in any practical embodiments
In hair, it is necessary to a large amount of implementation details are made to realize the specific objective of developer, such as according to relevant system or relevant business
Limitation, another embodiment is changed into by one embodiment.Additionally, it should think that this development is probably complicated and expended
Time, but it is only to those skilled in the art routine work.
More specifically description is of the invention by way of example referring to the drawings in the following passage.Will according to following explanation and right
Book is sought, advantages and features of the invention will become apparent from.It should be noted that accompanying drawing is using very simplified form and using non-
Accurately ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
Refer to Fig. 1 and Fig. 2, wherein, Fig. 2 be along Fig. 1 A to diagrammatic cross-section.In the present embodiment, it is proposed that one
Kind jaw face shell pen type goose saw structure, including：Housing 1, motor 2, put according to head main shaft 3, bearing 4, knife rest 5, saw blade 6 and shift fork 7,
Wherein, the motor 2 is arranged in the housing 1, described to put the rotor portions that the motor 2 is eccentrically arranged according to head main shaft 3
On point, the knife rest 5 connects the pendulum according to head main shaft 3 by the bearing 4, and the axle perpendicular to the pendulum according to head main shaft 3
Heart line, the saw blade 6 are fixedly installed on the knife rest 5, and the shift fork 7 is coaxially fixedly installed on the knife rest 5, described group
