Abstract
This utility model Handheld electric circular saw guard shield protection device, has and is arranged on the magnetic piece of electrotrephine guard shield side, the Hall Plate being arranged on electrotrephine housing side and the master control circuit plate being arranged on electrotrephine housing, and Hall Plate is electrically connected with master control circuit plate；Magnetic piece is overlapping with Hall Plate when electrotrephine guard shield is closed and is locked on electrotrephine housing, Hall Plate senses magnetic piece magnetic and provide power on signal, master control circuit plate to control for master control circuit plate motor brings into operation, the reduction gear box of final its outfan of driven by motor operate and drives saw blade to do sawing and works；When electrotrephine guard shield is opened or is removed from electrotrephine housing magnetic piece separate with Hall Plate, Hall Plate provide power-off signal, master control circuit plate to cause for master control circuit plate in the case of sensing is less than magnetic piece magnetic motor is out of service, finally make saw blade stop sawing work.When removing or opening guard shield, electrotrephine cannot start, thus protects operator's personal safety.
Description
Technical field
This utility model relates to the technical field of Handheld electric circular saw, especially a kind of Handheld electric circular saw guard shield
Protection device.
Background technology
Existing hand-held circular saw on market, it includes electrotrephine housing and guard shield, guard shield by hinge axis and
Nut is positioned on electrotrephine housing, and the latch hook of guard shield is scheduled on fixing by the bolt lock with electrotrephine housing one
In rotating range, when operator dismantles guard shield or opens guard shield chip removal and change saw blade, instrument error starting
Operator can be caused personal injury by rear saw blade.
Utility model content
The technical problems to be solved in the utility model: in order to overcome deficiency of the prior art, it is provided that a kind of hands
Holding formula electrotrephine guard shield protection device, when removing or opening guard shield, electrotrephine cannot start,
Thus protect the personal safety of operator.
This utility model solves the technical scheme that its technical problem is used: the protection of Handheld electric circular saw guard shield fills
Put, have be arranged on electrotrephine guard shield side magnetic piece, be arranged on electrotrephine housing side Hall Plate and
The master control circuit plate being arranged on electrotrephine housing, Hall Plate is electrically connected with master control circuit plate；Work as electrotrephine
When guard shield is closed and is locked on electrotrephine housing, magnetic piece is overlapping with Hall Plate, Hall Plate senses magnetic piece
Magnetic and for master control circuit plate provide power on signal, master control circuit plate control motor bring into operation, finally electricity
Machine drives the reduction gear box of its outfan to operate and drives saw blade to do sawing work；When electrotrephine guard shield from
When opening or remove on electrotrephine housing, magnetic piece separates with Hall Plate, Hall Plate is sensing less than magnetic piece magnetic
Power-off signal, master control circuit plate is provided to cause motor out of service, final for master control circuit plate in the case of property
Saw blade is made to stop sawing work.
The beneficial effects of the utility model: this Handheld electric circular saw guard shield protection device, protect closing and locking
Under the state of cover, electrotrephine normally starts；When removing or opening guard shield, electrotrephine cannot open
Dynamic, thus protect the personal safety of operator.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are showing of simplification
Being intended to, basic structure of the present utility model is described the most in a schematic way, therefore it only shows and this utility model
Relevant composition.
See Fig. 1, Fig. 2 and Fig. 3, this utility model Handheld electric circular saw guard shield protection device, have and be arranged on
The magnetic piece 10 of electrotrephine guard shield 2 side, it is arranged on the Hall Plate 11 of electrotrephine housing 1 side and is arranged on
Master control circuit plate 12 on electrotrephine housing 1, Hall Plate 11 is electrically connected with master control circuit plate 12.Magnetic
Sheet 10 and Hall Plate 11 are respectively positioned on the same side of electrotrephine, can all be arranged on the left side of electrotrephine, it is possible to
To be all arranged on the right side of electrotrephine.
See Fig. 1 and Fig. 3, the magnetic piece 10 when electrotrephine guard shield 2 is closed and is locked on electrotrephine housing 1
Overlapping with Hall Plate 11, utilize hall principle Hall Plate 11 to sense the magnetic of magnetic piece 10 and for master control line
Road plate 12 provides power on signal, master control circuit plate 12 to control, and motor 13 brings into operation, final motor 13 carries
The reduction gear box 9 of its outfan dynamic operates and drives saw blade 6 to do sawing work, thus ensures electrotrephine
Normal work.
See Fig. 2 and Fig. 3, the magnetic piece 10 when electrotrephine guard shield 2 is opened or removed from electrotrephine housing 1
Separate with Hall Plate 11, utilize hall principle Hall Plate 11 in the case of sensing is less than magnetic piece 10 magnetic
Thering is provided power-off signal, master control circuit plate 12 to cause for master control circuit plate 12, motor 13 is out of service, finally make
Saw blade 6 stops sawing work, thus protects the personal safety of operator.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant
Staff can carry out various change completely in the range of without departing from this utility model technological thought
And amendment.The content that the technical scope of this utility model is not limited in description, it is necessary to root
Its technical scope is determined according to right.
