Also, when the semiconductor package integrated circuits are stacked and transported and transported on the diagonal lines of the upper and lower surfaces when viewed on the plane of the main body 100, the semiconductor package integrated circuits are prevented from being freely moved or released to the outside The stopper 170 is inserted into the surface of the main body 100 when the stopper 170 is rotated so as not to interfere with the semi-finished product of the semiconductor integrated circuit device on both sides of the diagonally opposite sides of the upper surface and the lower surface, Receiving grooves 160 are formed to prevent the stopper 170 from protruding from the surface of the main body 100 to the outside while preventing contact interference with other adjacent magazines.

The stopper 170 may include a stopper 170 for holding the rotation shaft of the upper end of the stopper 170 by an elastic restoring force of a spring (not shown) inserted into a shaft not shown in the upper surface of the main body 100, Can always be positioned at the uppermost position in the rotatable range and can maintain a state in which the lower portion of the stopper 170 is in close contact with the bottom surface of the main body 100 as long as the stopper 170 is not depressed downward, It is needless to say that a conventional structure such as a method in which a slider cover structure is applied may be selectively adopted.

The handle 200 is formed with hinge shafts 210 at both ends in the longitudinal direction and the hinge shafts 210 are connected to the upper surface of the main body 100 by hinge joints.

That is, the knob 200 is folded horizontally with respect to the upper surface of the main body 100 while being rotated within a range of about 180 degrees in the width direction of the main body 100 with the hinge shaft 210 at both ends thereof as the center, And is mounted on the upper surface of the main body 100 so as to be spread and erected.

The handle 200 is bent horizontally with respect to the upper surface of the main body 100 in a "C" shape and a shape when the bar having a circular shape in cross section is viewed in a plan view, And the hinge shaft 210 is integrally formed by bending both ends of the portion in parallel with the original rod portion so as to bend back into an "a" or "b" shape and a shape.

The hinge hole 120 has a hinge shaft The hinge shaft 210 and the hinge hole 120 are simultaneously covered with the clamp plate 121 holding the inserted state of the clamp plate 121 and the clamp plate 121 is mounted on the upper surface of the main body 100 by means of bolts or screws. The handle 200 and the upper surface of the main body 100 are hingedly connected to each other so that the handle 200 is positioned on the upper surface of the main body 100, The permanent magnets 130 can be fixed at positions in the 0 ° and 180 ° directions opposite to the knob 200 when the knob 200 is folded in parallel in the 0 ° and 180 ° directions.

The permanent magnets 130 are symmetrically fixed to each other at positions adjacent to the hinge shaft 210 at both ends of the handle when viewed on the plane of the upper plate of the main body 100, The permanent magnets 130 multiply the pulling force of the knob 200 and the state in which the knob 200 is more firmly in contact with the upper surface of the main body 100 .

On the other hand, it is preferable that the permanent magnet 130 employs a heat resistant magnet such as a magnetic magnet having excellent heat resistance and corrosion resistance due to the characteristics of the semiconductor manufacturing process.

When the handle 200 is folded horizontally with respect to the upper surface of the main body 100, the permanent magnet 130 is strongly attracted to the upper surface of the gear main body 100 by the magnetic force, So that the handle 200 is not freely rotated unless the operator manually manipulates the handle 200 to rotate the magnet 200 out of the range of the magnetic force of the permanent magnet 130. [

Therefore, even if the upper and lower surfaces of the main body 100 are turned upside down in the semiconductor package manufacturing process, the handle 200 can be prevented from being freely rotated or hanged by its own weight.

That is, when the knob 200 is folded horizontally or vertically with respect to the upper surface of the main body 100, a part of the interference ball 400 is pulled by the tension force of the spring 300 on the bottom surface of the hinge shaft 210 So that the grip 200 is not freely rotated by its own weight unless the operator manually forcibly rotates the grip 200. As a result,

Here, it is preferable to use a compression coil spring made of stainless steel as the spring 300, but any one having the same effect can be used.
