Used as a kind of improvement of the present utility model, the body is at the position between the emery wheel and the assist handle
It is provided with dust-blocking cover.
Using above-mentioned technical proposal, the utility model has the advantages that：
1st, by setting two handles so that user grips and more stablizes, while by the grip position in main handle
On be provided with the first inductive switch, the second inductive switch is provided with the grip position of assist handle, when user wherein
After one hand leaves corresponding handle, the inductive switch on the handle is to be opened and cause that motor power-off is shut down, it is to avoid ground at angle
Machine slip out of the hand after emery wheel still in the injury that is likely to result in user of rotation, security is of a relatively high.
2nd, by setting acceleration induction device, when angle grinder produces strenuous vibration in use, acceleration induction
By signal transmission to control module, control module controls master switch to close and causes that motor power-off is shut down device again, further improves
Security performance.

Specific embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the angle grinder with dual-handle that the present embodiment is provided, including body 10 and be arranged in body 10
Motor (not shown), one end of body 10 is provided with the emery wheel 30 being connected with motor, and the other end is formed with main hand
Handle 40, the side of body 10 be provided with the position of emery wheel 30 with the orthogonal assist handle 50 of main handle 40, it is above-mentioned
The position of motor, emery wheel 30, main handle 40 and assist handle 50 and its with the attachment structure between body 10 all with it is conventional
Dual-handle angle grinder is identical, no longer describes in detail herein.
Preferably, in the present embodiment, assist handle 50 is arranged in parallel with emery wheel 30, and body 10 is in emery wheel 30 and auxiliary
Dust-blocking cover 11 is provided with position between handle 50.The past auxiliary of particle goods dust being ground when so can avoid using
Clash into or fly away in the direction of handle 50.
Main handle 40 is provided with master switch 41, and the grip position of main handle 40 towards one end of emery wheel 30 and is provided with
First inductive switch 42, the grip position of main handle 40 that is to say the position contacted with each other with the hand of user on main handle 40,
Positioned at the medium position of main handle 40, in other words, after the hand of user is held on main handle 40, master switch 41
In user on hand, and the first inductive switch 42 then contacts with each other with the hand of user.
The second inductive switch 51 is provided with the grip position of assist handle 50, likewise, the grip position of assist handle 0
It is also the position contacted with each other with the hand of user on assist handle 50, positioned at the medium position of assist handle 50, when using
After the hand of person is held on assist handle 50, the second inductive switch 51 contacts with each other with the hand of user.
Master switch 41, the first inductive switch 42, the second inductive switch 51 and motor are sequentially connected in series, and and angle grinder
Attaching plug be collectively forming circuit loop, so, as long as master switch 41, the first inductive switch 42 and the second inductive switch 51
In any one switch be disconnected, motor be power-off shut down, it is impossible to drive emery wheel 30 to rotate again.Additionally, in the present embodiment, it is main
Control switch 41 is the switch that angle grinder is commonly used, and the first inductive switch 42 and the second inductive switch 51 are all normal open switch, and are all
When the hand of contact witch, i.e. operator is not in contact with the first inductive switch 42 or the second inductive switch 51, the first sensing is opened
The inductive switch 51 of pass 42 or second is off, only when the hand of operator is opened with the first inductive switch 42 or the second sensing
When pass 51 is in contact, the first inductive switch 42 or the second inductive switch 51 can just be in closure state.So, process is being used
In, when slipping out of the hand or because it is that corresponding inductive switch can be disconnected that other reasonses hand unclamps from corresponding handle for user,
Motor is stopped, it is ensured that use safety.
Additionally, in the present embodiment, acceleration induction device and control module (not shown) are additionally provided with body 10,
Acceleration induction device and control module are all conventional electronic component, directly can commercially be obtained.Control module is distinguished
It is connected with acceleration induction device and the communication of master switch 41.So, when angle grinder produces strenuous vibration in use, should
Vibrations can degree of being accelerated inductor detect, after acceleration induction device detects vibrations, by signal transmission to control module, control
Module controls master switch 41 to close and causes that motor power-off is shut down again, further improves security performance.Certainly, acceleration induction device
The vibration amplitude that can be detected needs the sensitivity by adjusting acceleration induction device to open control, it is contemplated that angle grinder is in work
During inevitably produce slight vibrations, the sensitivity of acceleration induction device can not be too small, and specific sensitivity needs root
It is adjusted according to being actually needed.
The utility model is described in detail above in conjunction with accompanying drawing, but implementation method of the present utility model and not only
It is limited to above-mentioned implementation method, those skilled in the art can make various modifications according to prior art to the utility model, such as will
Master switch 41 in above-described embodiment is arranged on that body 10 is first-class, and these belong to protection domain of the present utility model.
