Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of high cutting force electric shear, comprising: shell 1, the shell 1 be internally provided with power supply unit 2 and with the confession
The motor 3 that electric installation 2 is electrical connected, and cutting mechanism is provided on the right side of the shell 1, which is characterized in that the cutting mechanism
It include: the transmission shaft 4 being connected with the motor 3, the ledger-plate 8 being fixed on the shell 1 and hinged with the ledger-plate 8
Cutting blade 7；
The left-hand end of the cutting blade 7 offers sliding slot 9, and the right-hand end of the transmission shaft 4 is equipped with gear set 5, the gear set 5
Center be fixedly installed with connecting rod 6, the connecting rod 6 is interspersed in the sliding slot 9 by removable pin 10.
It further illustrates, the gear set 5 is made of bevel pinion and bevel gear wheel engagement, passes through bevel pinion and big vertebra
The rotary force of transmission shaft 4 is passed to connecting rod 6 by the engagement of the tooth of gear, to drive connecting rod 6 around gear set 5 and connecting rod 6
Junction move in a circle so that the rotation of gear set 5 is turned around, cutting mechanism, that is, retractable is primary, does not need promptly to stop
Only and commutation comes so that gear set 5 carries out drawback movement, so that the control of motor 3 is simpler.
Further illustrate, the cutting mechanism further includes the Hall Plate 11 being fixedly mounted in casing 1, the Hall Plate
11 upper end is equipped with upper position sensor 12, and the lower end of the Hall Plate 11 is equipped with lower position sensor 13, described upper
Setting sensor 12 and the lower position sensor 13 is Hall sensor.
Further illustrate, the left-hand end center of the cutting blade 7 is fixedly mounted magnet 15, and the magnet 15 is along Hall
Plate 11 is swung between the upper position sensor 12 and the lower position sensor 13；When upper position sensor 12 sense it is dynamic
When magnet 15 in 7 left-hand end of blade, cutting blade 7 and ledger-plate 8 are in best closed state, and position sensor 13 incudes instantly
To 8 left-hand end of ledger-plate magnet 15 when, cutting blade 7 and ledger-plate 8 are in maximum open configuration.
Further illustrate, the upper position sensor 12 and the lower position sensor 13 pass through Hall Plate signal wire 16
It is connected with Hall switch 14, the Hall switch 14 is electrically connected with the motor 3, when upper position sensor 12 and lower position pass
After sensor 13 senses magnet 15, Hall switch 14 is sent a signal to by Hall Plate signal wire 16, to open by Hall
14 are closed to control the opening and closing of motor 3.
Further illustrate, the power supply unit 2 is any one of built-in battery packet or circumscribed battery pack.
Present invention discloses a kind of high cutting force electric shears, specifically use principle as follows:
Firstly, operator's rapid double tap Hall switch 14, activation motor 3 is operated, so that transmission shaft 4 is driven to start to rotate,
Under the action of gear set 5, transmission shaft 4 drives connecting rod 6 to be rotated again, and connecting rod 6 is interspersed in the cunning further through removable pin 10
In slot 9, so that connecting rod 6 drives cutting blade 7 to be swung while rotating, at this time since connecting rod 6 can be in sliding slot 9
It is moved, so that it drives the arm of force to gradually increase, and reaches maximum value in middle position, it is final to realize 7 He of cutting blade
Closure and opening between ledger-plate 8.
It is to be understood that the magnet 15 of 7 left-hand end of cutting blade is also swung during cutting blade 7 is swung, when
When magnet 15 is rocked to the upper position sensor 12 in Hall Plate 11, upper position sensor 12 senses signal, and passes through Hall
Partitioned signal line 16 sends a cut-off signal to Hall switch 14, and Hall switch 14 controls 3 power loss of motor again and shuts down, from
And guarantee that cutting blade 7 stops swinging, so that cutting blade 7 and ledger-plate 8 are able to maintain in best closed state, it is final to keep shearing
Power, after the completion of shearing, the quick two-shipper Hall switch 14 of operator be can be used continuously；And it is passed when magnet 15 is rocked to lower position
When sensor 13, lower position sensor 13 senses signal, and sends one to Hall switch 14 by Hall Plate signal wire 16 and break
ON signal, Hall switch 14 shuts down in control 3 power loss of motor, to guarantee that cutting blade 7 stops swinging, so that cutting blade
7 and ledger-plate 8 be able to maintain in maximum open configuration, convenient for the storage of dead status.
It is different from the prior art, a kind of high cutting force electric shear of the present invention is interspersed in the sliding slot by using connecting rod 6
Drive mechanism in 9, for replacing existing crank link mechanism, so that when driving cutting blade 7, driving force
Arm gradually increases, and reaches maximum value in middle position, greatly improves cutting power.
In the description of the present invention, it should be noted that the instruction such as term " on ", "lower", "left", "right", "inner", "outside"
Orientation or positional relationship be based on the orientation or positional relationship shown in the drawings or the invention product using when usually put
