Description
Technical field
The utility model relates to field of power tools more particularly to a kind of electric circular saws with flexible blade guard.
Background technique
Electric circular saw is a kind of very common electric tool, is usually used in the cutting and processing of metal product or woodwork.By
In being directed to high speed saw blade, therefore its safety is an important index.All having in existing electric circular saw can be automatic
The shield of closure, shield are made of casing and dynamic shield, for protecting saw blade, prevent injury accident when operation.
In saw blade is located at by shield, wherein dynamic shield can rotate around saw blade, and disc spring elastic force is leaned on to cover saw blade automatically.
Existing electric circular saw, dynamic shield are closed automatically when stopping using, and are covered saw blade and are realized protection, but due to
When electric circular saw carries out cutting operation, dynamic shield one end is connect with Electrotrephine case, and the other end is due to needing to be against work to be cut
On part, therefore the other end is located at below electric circular saw bottom plate, and casing is positioned at bottom plate above, dynamic this end of shield not with casing
Contact, dynamic shield only have one end to connect with casing.Therefore it finds in actual use, stores transportational process in electric circular saw
In inevitably collide extruding, leading to dynamic shield, deformation occurs, after especially dynamic shield closure merely by and casing
Link position is securing, is all easy to cause dynamic shield by the external force of a little in dynamic shield moving direction upright position
It bends, active path changes, and causes dynamic shield and saw blade to be bonded closely, is easily damaged saw blade, Er Qiedong instead
Shield deformation after rotation have some setbacks, noise it is big, or even saw blade rotation when with dynamic shield occur friction lead to safety accident.
Therefore, how existing electric circular saw is improved, make its overcome drawbacks described above be those skilled in the art urgently
The problem solved.
Summary of the invention
In view of the above-mentioned state of the art, have the technical problem to be solved by the utility model is to provide one kind and live

It is arranged on casing, the saw blade and the bottom plate are vertically arranged and pass through among the bottom plate, the casing and the electricity
Machine is mounted on above the bottom plate, the rotation of saw blade described in the motor driven, and saw blade top is stated in the chassis cover residence, described dynamic
Shield, which is located at below the casing, covers the saw blade lower part, and the dynamic shield is arc, the center of circle of the dynamic shield
Be overlapped with the saw blade center of circle, the dynamic shield can rotate on itself circular path, described dynamic shield one end with it is described
Casing connection, the other end electric circular saw using when offset company with product to be cut, the dynamic shield is as electric circular saw is to be cut
The cutting cut on product is advanced, and the dynamic shield, which can rotate, to be retracted in the casing, after the completion of cutting, the dynamic protection
Cover is no longer supported and is connected on product to be cut, and the dynamic shield produces described in covering out of described casing under the effect of disc spring elastic force
Then saw blade lower part can skid off one end of the support cover out of described dynamic shield, until the locking piece can will be described
The end that skids off of support cover is fixed, and the other end of the support cover is still located in the dynamic shield at this time, the dynamic shield
Both ends are fixed, and when electric circular saw storage is transported, the dynamic shield is not easy compressive deformation.
Further, the cross section of the dynamic shield and the support cover is in U-typed, and the support enclosure is located at
In the dynamic shield.
Specifically, the support cover is arc-shaped, the center of circle of the support cover is overlapped with the center of circle of the dynamic shield, described
Support cover can rotate on itself circular path.
Further, the both side plate of the dynamic shield is recessed arc-shaped guide rail, the side plate concave shaped of the support cover
Camber guide groove, the arc guide barrel and the arc-shaped guide rail form sliding cooperation.
Specifically, the center of circle of the arc guide barrel and the arc-shaped guide rail is overlapped with the center of circle of the dynamic shield.Together
When, arc guide barrel and arc-shaped guide rail are set, the intensity of the dynamic shield and the support cover is strengthened.
Further, the dynamic shield side offers short slot, and the support, which is covered, is fixedly installed driving lever, and described group
Bar one end is pierced by from the short slot.
Specifically, one end of the driving lever and the support cover are fixedly connected, the other end from it is described stir the driving lever can
The support is set to cover on sliding in the dynamic shield.
Further, the locking piece includes the locking seat being fixedly mounted on the bottom plate, setting in the locking seat
There is the locking pin of flexible installation, one end of the support cover is provided with fixation hole, and the locking pin forms slotting with the fixation hole
Pull out cooperation.
Specifically, being provided with shifting block in the locking seat, the shifting block lower end is fixedly connected with locking pin, and the shifting block can
It is slided in the locking seat along the locking pin telescopic direction, sliding the shifting block keeps the locking pin flexible.Work as electric circular saw
After use, when needing the support covering fixed, stretch out the locking pin in the fixation hole on the insertion support cover, it is real
The fixation of the existing support cover, using before electric circular saw, extracts the locking pin from the fixation hole, and make the branch next time
Support cover slides into the dynamic shield.
Further, the quantity of the fixation hole and the locking pin is two.
Specifically, using two parallel locking pins, it is stronger reliable after fixed.
The utility model has the advantages that
Using technical solution provided by the utility model, compared with prior art, have the following beneficial effects:
A kind of electric circular saw with flexible blade guard of the utility model, the dynamic interior sliding of shield are provided with support cover,
Support cover can be fixed after skidding off, and fix shield both ends can, overcome dynamic shield in traditional electric circular saw and there was only one end
The defect being capable of fixing, makes that shield will not deformation occurs, it is ensured that dynamic shield extends the use of electric circular saw using safe
Service life reduces noise when dynamic shield closure.
