Iron 401b is powered with the battery 401i being arranged on 302 upper surface of the first support column and connects.
In the present embodiment, the application method of the compressed part 401 is as follows:
First, when the compressed part 401 is left unused, the electromagnet 401b is not powered on, and the iron core of the electromagnet 401b
Part be it is nonmetallic, be used only for fixed coiling electromagnet coil, the pressure plate 401c is pulled up by the tension spring 401e at this time
To a high position, facilitate the discarded circuit board 2 puts operation；
Second, after the discarded circuit board 2 is well placed, control is connected to the electromagnet 401b and battery 401i,
So that the electromagnet 401b generates the magnetic field to attract each other with the permanent magnet 401h, the related pressure of permanent magnet 401h
Tight plate 401c is moved down, and is finally pressed on the discarded circuit board 2, completes to compress operation；
Third when the discarded circuit board 2 needs to take out, disconnects the circuit of the electromagnet 401b, the pressure plate
401c returns a high position.
Therefore the compressed part 401 has the advantage that
First, the pressure plate 401c, as driving force is compressed, are had switch flexibly and intensity are enough excellent using magnetic force
Point；
Second, the ball 401g be used for guarantee the sliding ring 401a it is stable slide up and down movement, avoid the cunning
There is stuck problem on the limited post 301 in moving-coil 401a；
Third, the tension spring 401e lift for guaranteeing that the compressed part 401 has when idle to the discarded route
The advantages of plate 2 is placed, eliminates unnecessary opening operation when placement.
The weight portion 402 includes the installation circular groove 402a being arranged on 303 upper surface of the second support column, and setting exists
Pedestal 402b in the installation circular groove 402a, the hinged seat 402c and one end being arranged on the pedestal 402b are hingedly set
Set the weight plate 402d on the hinged seat 402c.
In the present embodiment, the weight portion 402 has the advantage that
First, the weight plate 402d are pushed by gravity, have the advantages that pressuring action is persistently effective；
Second, the weight plate 402d be vertical, horizontal direction can hinging rotary, expand weight effective range.
The linkage portion 403 includes the swivel mount 403a being arranged on 302 upper surface of the first support column, hinged to be arranged
Swivel plate 403b on the swivel mount 403a, it is hinged to be arranged on the inner end the swivel mount 403a and be used to install described
The conducting block 403c of electromagnet 401b conducting wire, and be arranged on the battery 401i and pass through and pull down the conducting block 403c
Mode is for electrode the tension spring 403d, the electrode tension spring 403d and the battery for being connected to the electromagnet 401b that be powered
A projected electrode of 401i is socketed.It is equipped on the swivel plate 403b different from the side that the conducting block 403c is arranged and passes through institute
Linkage when weight plate 402d is tilted and disconnected the electromagnet 401b circuit mode to take out for the discarded circuit board 2 is stated to beat
Open the pushing slot 403e in the compressed part 401 and weight portion 402.
In the present embodiment, there are two working morphologies for the tool of linkage portion 403:
First, the linkage portion 403 is connected to the electromagnet 401b during support compression, for being powered, at this time institute
It states conducting block 403c to be pulled down and withstood on an electrode of the battery 401i by the electrode tension spring 403d, guarantees entire electricity
Road is unobstructed, and the weight portion 402, which should also rotate, at this time is pressed on the discarded circuit board 2, cooperates the compressed part 401, complete
Operation is compressed at entire；
Second, when the discarded circuit board 2 needs to remove, lifts and rotate the weight plate 402d, and ride over corresponding position
On the pushing slot 403e set, the conducting block 403c is lifted away from the battery 401i at this time, and the compressed part 401 loses
Magnetic force simultaneously lifts to position to be compressed, and the entire fastening unit 4 is opened, and facilitates the loading or unloading operation of the discarded circuit board 2, therefore
The linkage portion 403 has the connection validity that is powered high, and control disconnects flexible two-fold advantage.
