Description
Technical field
The present invention relates to a kind of electric tool, more particularly to a kind of hand held electric tool.
Background technology
A kind of currently known electric tool with detachable battery packet, especially hand held electric tool.This is electronic
Tool due to vibration, may result in the connection of the leading-out terminal and electric tool connected to it of battery pack in use
Poor contact is generated between terminal, it is also possible to electric tool and battery pack can be caused to generate thermal deformation.In particular, when battery pack connects
When continuing by stronger vibration, it is possible to cause cell device and circuit inside battery pack to be damaged, and then influence battery
The service life of packet and security performance.
If in working at height, the high vibration of electric tool or unexpected touching are also possible to lead to battery pack and electricity
Being fixedly connected between power driven tools, which loosens, to be even resulted in battery pack and falls, and is at this moment easier to bring security risk.
Invention content
If in working at height, the high vibration of electric tool or unexpected touching are also possible to lead to battery pack and electricity
Being fixedly connected between power driven tools, which loosens, to be even resulted in battery pack and falls, and is at this moment easier to bring security risk.
To achieve the above objectives, a kind of electric tool of the invention, including：Shell can accommodate the master of the electric tool
Body；Battery pack is movably connected with the shell, and provides electric energy to the electric tool；Operating unit is located at the electricity
Pond is wrapped, and the battery pack can be made to be unlocked from the shell；Battery pack secondary locking unit, the secondary locking unit packet
At least one locking member and at least one holding member are included, wherein at least one locking member may be provided at the shell or institute
It states in battery pack, at least one holding member is arranged in the battery pack opposite with the locking member position or the shell
On body, the battery pack secondary locking unit further includes the connector for connecting the locking member with the holding member,
The holding member can be set as raised buckle, and the locking member is mounted on the screw pole of the housing base, the locking member
It can be resilient tightening band.
Further, the connector is annular steel ring.
Further, when the resilient tightening band, which is in, draws high state, the connector is because by the elastic tension
The pulling force of band and with the buckle realization be fastenedly connected.

The present invention will be further described below with reference to the drawings.
Fig. 1 is the electric tool structure figure of one embodiment of the present of invention.
Fig. 2 is the electric tool structure figure of second embodiment of the present invention.
Fig. 3 is the electric tool locking state structure chart of second embodiment of the present invention.
Fig. 4 is the electric tool structure figure of the third embodiment of the present invention.
Fig. 5 is the battery pack structure figure of the present invention.
Specific implementation mode
The electric tool of the present embodiment is related to a kind of electric tool, especially hand held electric tool.The electric tool packet
Shell 1 is included, the main body for accommodating the electric tool, such as motor and gear-box.
Electric tool as shown in Figure 1, the housing of electric tool 1 include the gripping handle 2 being disposed below and shell bottom
Seat 3.Housing base 3 is equipped with the screw pole 4 for fastening left and right shell.There are one can give its offer electricity for electric tool tool
The battery pack 6 of amount.6 shell of battery pack corresponding direction vertical with screw pole 4, which is set, several protrusion buckles.As shown in Figure 5
Battery pack 6, which is configured to sliding battery pack, when battery pack 6 is moved to final position along glide direction 12
When, battery pack 6 is locked at by main locking system 10 on the housing base 3 of 2 lower end of handle.10 clamping lock of main locking system is in shell
In the lactch groove that body pedestal 3 is not shown specifically.It, can be single by operating operation when battery pack is moved along removing direction 13
Member 11 makes battery pack 6 be unlocked from electric tool, can separate the battery pack 6 and electric tool after the unlock of battery pack 6.
Glide direction 12 and removing direction 13 are substantially vertical in handle orientations.
Electric tool 1 further includes battery pack secondary locking unit, which includes 5 He of at least one locking member
At least one holding member 8.Wherein, at least one locking member 5 is fixed on the screw pole 4 of housing base 3, and holding member 8 is set
It sets on battery pack case.Holding member 8 in the present embodiment is that at least one protrusion buckles, and locking member 5 is preferably elasticity
The elastic force of taut band, the tension band is selected by many experiments.
After battery pack is packed into electric tool along glide direction 12, before not actuated switch trigger, pull downward on elastic
Band elongates elastic band until on the protrusion buckle on battery pack case, battery pack and machine can be may be implemented with hanging buckle
Auxiliary fastening.
Electric tool as shown in Figure 2, it is preferably that annular steel ring is set on locking member to have a connection piece 7.
As shown in figure 3, when pulling downward on elastic band, gradually elastic band is elongated until can be by 7 hanging buckle of connector in electricity
On protrusion buckle on the incrustation of pond, at this time since connector 7 is by the pulling force of elastic band so that itself and the protrusion in battery pack
Buckle firmly coordinates, and will not loosen.It is further ensured that battery pack is auxiliarily fixed on electrician tool shell 1.
Even if the whole of electric tool generates high vibration or generates unexpected touching volume, it is also ensured that battery pack will not
It falls, causes danger.
Obviously the fixed form of locking member is not limited to this, and locking member 5 can also be directly fixedly clamped by shell.It keeps
Component can also be set as groove.Connector is set as a plug connector and is inserted into realizing in the holding member and being connected and fixed.This field skill
Art personnel are not difficult to be inferred to that locking member is mounted in battery pack and raised bayonet is arranged on shell similarly to may be implemented
Fastening effect same as the present embodiment.So other similar fixing means, different installation positions, the recess of holding member
It is related to also belonging in the scope of the present invention.
As shown in figure 4, another embodiment of the present invention.Locking member 5 can be a rotary part.The rotary part is rotatable
It is supported on the screw pole 4 of housing base 3.In the embodiment, the connector 7 being connected with locking member 5 is preferably opened
Choma shape steel ring.
After battery pack is packed into electric tool along glide direction 12, before not actuated machine switch trigger, rotary part 9
Top be located remotely from the side of housing base 3, there is no be connected with the protrusion buckle in battery pack for connector 7.Work as rotation
When rotation member 9 is towards close to housing direction rotation, rotary part 9 moves up to the card in battery pack with follower link 7
In button 8, when rotary part 9 moves to extreme position, connector 7 and buckle 8 are realized and are fitted close, and then battery pack is fixed
On shell 1；When rotary part 9 is rotated away from 1 direction of shell, rotary part 9 moves downwardly to de- with follower link 7
From the protrusion buckle in battery pack, the fastening between battery pack 6 and shell 1 at this time is released.
Those skilled in the art are not difficult to infer that other, similar to fixing means, are also belonged in the scope of the present invention.Locking member
It is also belonged in the scope of the present invention with the evolution of holding member.
Facts have proved a kind of electric tool provided by the invention, due to secondary locking unit, when vibrate it is too drastic or
When unexpected touching occurs, the relative friction between electric tool and battery pack can be significantly reduced, prevents the accident of battery pack from falling
It falls, ensure that the stability of electrical connection, more extend the service life of battery pack.
