Wedge angle inclined-plane on limited block is with the matched effect of the first guide block:On the one hand, when the first spring is uncompressed
When, there is limited block the one end on wedge angle inclined-plane not enter in square type cylinder, and the first guide block is in contact with wedge angle inclined-plane, and such the
One guide block can be limited in the case of not by external force under the double action on the first spring and wedge angle inclined-plane;On the other hand,
First guide block is moved down along the first arc-shaped guide rail to be needed to meet, and external force is oblique more than the resistance of the first spring and limited block wedge angle
The limit power in face could make the first guide block move down.Such design is, preferably limits the first guide block.
Coil on sliding groove is with the matched effect of magnetic block:After coil is powered, under the action of electromagnetic induction,

Plate does arcuate movement around the axle center of flywheel;Arc-shaped limit plate can drive the second guide block to separate second spring through link block
It moves in direction.In addition the design of ladder-block and ladder type notch is advantageous in that, when magnetic block occurs moving by a small margin under electromagnetic induction
When dynamic, ladder-block can still enter in ladder type notch, and only ladder-block can not be completely into in ladder type notch;Due to ladder
Type block and ladder type notch are ladder type design, and the inclined-plane of ladder type incision can thus be allow to squeeze the inclined-plane of ladder-block,
Under the action of inclined-plane, ladder-block can be completely expressed in ladder type notch;It can thus generate in magnetic block and move by a small margin
When dynamic, magnetic block can drive ladder-block to enter in ladder type notch, and then ladder-block will not be easily detached from from ladder type notch,
And under the action of ladder type inclined-plane, ladder-block can be completely expressed in ladder type notch, and final flywheel drives ladder-block completely
Movement.Also since ladder-block and ladder type notch belong to trapezoidal-structure meshing relation, so flywheel drives ladder-block movement can more
The stabilization added.Third spring can be such that magnetic block movement resets.
There is sawtooth, arc-shaped limit plate to be evenly distributed latch on the arcwall face of ring-like saw blade on ring-like saw blade,

During arcuate movement, arc-shaped limit plate can be there are one upward moving process, and during arc-shaped limit plate moves up, arc
Shape limiting plate can be increasingly closer to ring-like saw blade;After engagement on latch and the ring-like saw blade on arc-shaped limit plate, arc
Shape limiting plate limits ring-like saw blade.
Magnetic block and ladder-block are much smaller for flywheel and ring-like saw blade in the present invention, thus in coil wink
Between be powered after, under electromagnetic induction effect, the much smaller magnetic block of quality can generate larger movement with moment, so that ladder type
Block generates cooperation with corresponding ladder type notch.But when utilizing electromagnetic induction principle so that ladder-block is directly produced with ring-like saw blade
Raw limit is designed with many flaws.For example, when weaker due to electromagnetic induction, ladder-block moment produces position by a small margin
It moves, but displacement by a small margin generates limit insufficient for ladder-block and ring-like saw blade, and then lose protection user's
Effect;In addition, in order to ensure that ladder-block can have significantly displacement, then just the quality of ladder-block is relatively made to become smaller, it can
It is that the small ladder-block of quality is not easy to generate rigid limit with the big ring-like saw blade of quality again, so this is a pair of very contradictory
Relationship.In order to avoid this pair of of contradictory relation, so introducing the design of flywheel in the present invention, such flywheel can be by small and exquisite
The movement of flexible magnetic block and ladder-block so that flywheel generates connection relation with arc-shaped limit plate, and such flywheel can incite somebody to action
The large energy of the storage of itself passes to arc-shaped limit plate, and then arc-shaped limit plate can obtain large energy, and can be with
Larger displacement is generated with flywheel, such arc-shaped limit plate just preferably generates limit with ring-like saw blade.
The axle center of central point and flywheel in the present invention where the first arc-shaped guide rail coincides, and wobble plate one end is mounted on first
On axis, the other end is mounted on the second axis, and the design that the second arc-shaped guide rail is mounted in wobble plate is, when ring-like saw blade is to moving down
In dynamic process, ring-like saw blade and the first guide block can be moved down along the first arc-shaped guide rail, and ring-like saw blade and first is led
The movement locus of block is to do arcuate movement around the axle center of this flywheel;In order to can guarantee that ring-like saw blade is moving down process
In, arc-shaped limit plate remains spacing relation with ring-like saw blade, so must assure that arc-shaped limit plate is generated with ring-like saw blade
Relative position after limit remains constant.Wobble plate in the present invention can surround the axle center of flywheel under the drive of first axle
Rotation, then the second arc-shaped guide rail can follow wobble plate around flywheel axle center rotate, can thus make arc-shaped limit plate with
It is rotated around the axle center of flywheel with the second guide block in the second arc-shaped guide rail, finally can be achieved with arc-shaped limit plate and ring-like saw blade
It generates the relative position after limit and remains constant.
When bench saw works normally, when the first spring is uncompressed, the first guide block is located at the top of the first arc-shaped guide rail;Limit
There is position block the one end on wedge angle inclined-plane not enter in square type cylinder, and the first guide block is in contact with wedge angle inclined-plane;Ladder-block not into
Enter into ladder type notch;When second spring is not stretched, the second guide block is located at the centre position of the second arc-shaped guide rail.Motor is through driving
Moving axis, driving wheel, the first belt, the first driven wheel drive first axle rotation, first axle to drive ring-like saw blade rotation;Motor is through driving
Moving axis, driving wheel, the second belt, the second driven wheel, Transmission gear drive the rotation of the second axis;Second axis drives flywheel rotation, flies
Wheel rotation energy storage;The direction of rotation of flywheel is opposite with the direction of rotation of ring-like saw blade.
When the hand of user touches annular blade in a flash, the relatively large capacitance of inside of human body will change telecommunications
Number, electric signal is passed to controller by identifier, after controller analyzes electric signal, is then controlled motor and is stopped.After motor stops,
Driving wheel stops rotating, but under ring-like saw blade and the rotatory inertia of first axle, annular blade will not immediately stop rotating.
Controller controls motor while stop, and controller moment gives coil to be powered, and under electromagnetic induction, magnetic block moment is to far from the
The direction of three springs is moved, and third spring is stretched;Ladder-block moment is inserted into the corresponding ladder type notch of flywheel;It is cut in ladder type
Mouthful and the ramp effect of ladder-block under, ladder-block moment is completely into in ladder type notch;In the case where the rotation of flywheel drives, ladder type
Block drives arc-shaped limit plate to do arcuate movement around the axle center of flywheel through magnetic block, and arc-shaped limit plate moves up;Arc limits
Position plate drives the second guide block to be moved to the direction far from second spring along the second arc-shaped guide rail through link block, and second spring is drawn
It stretches;And arc-shaped limit plate move up during, the latch on arc-shaped limit plate and the engagement on ring-like saw blade, arc
Limiting plate limits ring-like saw blade, arc-shaped limit plate moment stop motion, and then flywheel also moment stop motion.Ring-like saw at this time
Piece moment stops rotating, and then in the case where the angular momentum of ring-like saw blade drives, ring-like saw blade can there are one return to becoming in mechanism chamber
Gesture;Since the moment driving force of angular momentum offer at this time is more than the limit power of the resistance and limited block wedge angle inclined-plane of the first spring,
So ring-like saw blade drives the first guide block to be moved down along the first arc-shaped guide rail through first axle, the first spring is compressed;First
Guide block squeezes wedge angle inclined-plane, then there is limited block the one end on wedge angle inclined-plane to be extruded in square type cylinder, limit spring is compressed;
During the first guide block moves down, the first guide block drives wobble plate to be rotated around the axle center of flywheel through first axle, and then arc
The relative position that limiting plate is generated with ring-like saw blade after limit remains constant, finally during ring-like saw blade moves down
Always limited by arc-shaped limit plate, it is therefore prevented that ring-like saw blade move down during rotation.It was moved down in the first guide block
Cheng Zhong, the first guide block drive the first driven wheel to move down through first axle;During the first driven wheel moves down, first from
Driving wheel will be gradually reduced to the distance between driving wheel, and then the first belt would be at relaxed state, be avoided and be lost in motor
Still drive the rotation of the first driven wheel through driving wheel and the first belt under control, so avoid the first driven wheel after transmission according to
So so that the possibility of annular blade rotation, more protects the safety of user.The present invention is made using the moment of electromagnetic induction
It can firmly make ladder-block moment enter in corresponding ladder type notch, and flywheel and arc-shaped limit plate can be generated connection
Relationship, and then flywheel gives the energy transmission of storage to arc-shaped limit plate, flywheel driven after connection arc-shaped limit plate generate compared with
Big displacement, such arc-shaped limit plate just preferably generate limit with ring-like saw blade, finally so that ring-like saw blade moment stops, protection
The safety of user.In addition, making the time of the limit of ring-like saw blade extremely short using electromagnetic induction principle, matches in excellence or beauty and pacify in tradition
Full court saw utilizes the instant impact of gunpowder explosion;Simultaneously conventional security bench saw is also avoided using the design of electromagnetic induction principle
The middle complicated process dismantled machine and carry out filling gunpowder again, substantially increases the working efficiency of bench saw.
After the stopping of ring-like saw blade moves downward, under the reset force of the first spring, the first guide block is restored to home position,
And then the first guide block drives the first driven wheel and ring-like saw blade to be restored to home position through first axle;First belt is again by rubbish
Tightly;Under the reset response of third spring, magnetic block and ladder-block are restored to home position;In the reset response of limit spring
Under, limited block is restored to home position.After equal bench saws are completely recovered to normal condition, user makes again by motor is started
It obtains ring-like saw blade and continues rotary work.
Relative to traditional bench saw technology, user in the present invention touches high-speed rotating ring-like saw because burst is unexpected
When piece, motor is stopped, and coil moment is powered;Under electromagnetic induction effect, ladder-block moment is inserted into corresponding ladder type notch
In, so flywheel drive arc-shaped limit plate do arcuate movement around flywheel axle center, the latch on final arc-shaped limit plate with it is ring-like
The sawtooth of saw blade limits, and ring-like saw blade moment stops, and protects the safety of user;During ring-like saw blade moves down,
Ring-like saw blade is limited by arc-shaped limit plate always, more improves safety.During other first driven wheel moves down, the first skin
Band can gradually fluff, and avoid the first driven wheel after transmission still so that the possibility of annular blade rotation, is more protected
The safety of user.The configuration of the present invention is simple has preferable safety and using effect.
