Specific embodiment:
Embodiment: the utility model provides a kind of miniature goose saw, makees below with reference to attached drawing to the embodiment further
Detailed description.
As shown in Figures 1 to 6, the present embodiment protects a kind of miniature goose saw, including sequentially connected cutter 5, cutter to lock machine
Structure 30 and transmission mechanism 40, tool lock system 30 lock cutter 5, and transmission mechanism 40 is swung with cutter 5.
Referring to figs. 1 to Fig. 4, tool lock system 30 includes cutter positioning shell 8, swing rod 11, foundation 1, top cover 7, limit
Bar 4, the first spring 6, bearing 2 and washer 3.Wherein, cutter positioning shell 8 is main support, including first annular set 81 and with the
The second vertical annular sleeve 82 of one annular sleeve 81.Foundation 1 is at least partly vertically threaded through in first annular set 81, and one end and the
One annular sleeve 81 pushes against, and the other end is connect with top cover 7.Foundation 1 includes the first flange 11 being successively disposed adjacent from the bottom up, the
Two flanges 12 and third flange 13, and diameter is sequentially reduced.First flange 32 therein is pushed against with first annular 81 lower end surface of set,
Second flange 33 is the shaft shoulder cooperated with bearing 2, third flange 34 and 11 secure fit of swing rod.Swing rod 11 is placed in first annular set
It on 81 and is vertically set on foundation 1, equipped with the first perforation cooperated with foundation 1.11 upper surface of swing rod and 5 company of engagement of cutter
It connects, the other end is connect with transmission mechanism 40.Cutter 5 includes groove 51, and swing rod 11 includes the protrusion 31 cooperated with groove 51, groove
51 include at least two.In the present embodiment, for the ease of the installation of cutter 5, groove 51 is usually uniformly arranged on the first perforation
For on the annulus in the center of circle, protrusion 31 is equally arranged.Cutter 5 is fixed on cutter lock in the way of engagement in the present embodiment
In tight mechanism 30, mode is compressed relative to traditional cutter, clamping force enhancing makes cutter not generate movement in Impact direction,
Improve the reliability of cutter.
Further, gag lever post 4 is at least partly arranged in foundation 1, and 4 one end of gag lever post is in clamping connection with top cover 7, another
End is movable end, is exposed to more than foundation 1 outer.First spring 6 is set in the on gag lever post 4 and one end and gag lever post 4
Four flanges 41 push against, and the top inner wall of the other end and foundation 1 pushes against.Bearing 2 is set between foundation 1 and first annular set 81, can
It is also possible to multiple to be one, in the present embodiment for two, 2 lower end of bearing and the second flange 33, which push against, to be cooperated, upper end
It pushes against and cooperates with washer 3.When 11 stress of swing rod is swung, band cutter 5 is swung simultaneously with foundation 1, therefore foundation is relative to foundation 1
Occur to relatively rotate toward renaturation.
Top cover 7 is located at cutter 5 and 11 junction of swing rod, equipped with gag lever post 4 cooperate first buckle 71 and with bottom
The second buckle 72 that column 1 cooperates.
When needing that cutter is installed, it is only necessary to jack up gag lever post 4 upwards, top cover 7 is jacked up and removed, and makes cutter 5 and swing rod
The exposure of 11 junctions, after the groove 51 of cutter 5 is aligned with protrusion 31, then top cover 7, then gag lever post 4 pushes up upwards again
It rises, and top cover 7 is connect with gag lever post 4, under the elastic force effect of the first spring 6, top cover 7 falls and is located at cutter 5 and pendulum
Cutting tool installation manner is completed in 11 junction of bar.Therefore the present embodiment can not needed by extraneous work by dexterously mechanical cooperation
In the case where tool, the dismounting of cutter 5 is easily carried out, it is time saving and energy saving.
- 2 and 5-6 referring to Fig.1, transmission mechanism 40 include the shift fork 14 connecting with swing rod 11, the bias connecting with power source
Axis 18 and set on 18 one end of eccentric shaft and the shifting component that cooperates with shift fork 14, shift fork 14 is at least partially disposed in the second annular sleeve
In 82, and swing rod 11 is at least partially disposed in the second annular sleeve 82, that is to say, that swing rod 11 passes through the second annular sleeve 82 and shift fork
14 connections.
It is connected between shift fork 14 and swing rod 11 by the second straight pin 10.Specifically, straight pin 10 is threaded through shift fork 14 1
In two perforation at end, 11 one end of swing rod is in clamping connection with the second straight pin 10, and therefore, shift fork 14 swings, by the
The swing is passed to swing rod 11, swing rod 11 is made to swing therewith by two straight pins 10.
Shifting component includes the connected ball 22 being set on the eccentric shaft 18, is set between connected ball 22 and eccentric shaft 18
Bearing 24, shift fork 14 include fluting 141, connected ball 22 be located at fluting 141 in realize eccentric shaft 18 rotation and drive shift fork
14 reciprocating rotations.Shifting component further include set on 24 side of bearing shaft block ring 27, be set to bearing 24 and shaft block ring 27 it
Between spacer ring 26 and hole elastic spring 21 set on 24 other side of bearing, to limit bearing 24 and connected ball 22
Position setting.
Transmission mechanism 40 further includes the first straight pin 13, and 13 both ends of the first straight pin are threaded through cutter positioning shell 8 simultaneously
And on shift fork 14.I.e. shift fork 14 is located in cutter positioning shell 8 and will be outside shift fork 14 and cutter positioning by the first straight pin 13
Shell 8 is fixed, in this way, shift fork 14 is that rotation center rotate toward renaturation with first straight pin 13.
With continued reference to Fig. 1-2, which further includes connected with outer casing 28, connected with outer casing 28 and 8 spiral shell of cutter positioning shell
Line connection, transmission mechanism 40 are at least partially housed in connected with outer casing 28.In the present embodiment, transmission mechanism 40 includes the first sealing
Circle 12 and the second sealing ring 9, wherein the first sealing ring 12 is set between shift fork 14 and cutter positioning shell 8, to lock to cutter
Being sealed property is handled between mechanism 30 and transmission mechanism 40.Second sealing ring 9 is set to connected with outer casing 28 and cutter positioning shell 8
Between, thus we are it is found that shift fork 14 is located at the rear end of cutter positioning shell 8 Yu 8 junction of cutter positioning shell, as a result, I
Cutter positioning shell 8 and being sealed property of the external world can be handled.Therefore, the transmission mechanism 40 of the miniature goose saw is by fine
Leakproofness protection, waterproofness is splendid, to prevent in operation and cleaning process, liquid flow into internal body, thus extend make
Use the service life.
18 rear end of eccentric shaft is connect with power source, equipped be set in connecting shaft 17 on eccentric shaft 18, connection connecting shaft 17 with
The straight pin 16 of eccentric shaft 18 connect lantern ring 15 with the transmission shaft before connecting shaft 17 set on eccentric shaft 18 and is sheathed on partially
In mandrel 18 and one end connect the second spring 19 of the abutting of lantern ring 15 with the eccentric shaft abutting other end with transmission shaft.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as protection scope of the present invention.
