It is possible to form a screw hole in the housing 1 and to fasten the screw hole to the support shaft of the rotary shaft 102. However, when the thickness of the housing 1 forms a thread and is not thick enough to support the support shaft, the illustrated pusher support 105 is required, and the pusher support 105 is present according to the thickness of the housing 1. [ Can be determined.

A housing area 101, a guide 103, a fixed electrode 106, and a flow electrode 107 are disposed inside the housing 1.

The guide 103 restricts the flow electrode 107 from escaping from the accommodating region 101. [ The guide 103 can be formed so as to protrude toward the inside of the storage area 101 from the rim of the storage area 101. [

The fixed electrode 106 is in electrical contact with the electrode of the battery 5, and may include a metal plate or a spring. When the electrode is formed by a metal plate or a spring, it may protrude toward the electrode of the battery 5.

The flow electrode 107 is in electrical contact with the electrode of the battery 5, and may comprise a metal plate or a spring. However, the flow electrode 107 can flow in the storage region 101 in the direction D1 or D2 by means of the rotating bar 102. At this time, the flow direction of the flow electrode 107 is restricted by the guide 103 and does not leave the storage region 101. [

Fig. 3 shows the structure of the pivot support 105. Fig.

3, the pivot support 105 is a structure protruding from the outer periphery of the housing 101, and a support hole 105a is provided at the center.

A screw thread is formed on the outer periphery of the support shaft 102c and is fastened to the screw hole 105a on the side of the rotary support 105. [

That is, the rotary shaft 102 can be mounted on the housing 1 by the support shaft 102c and turned.

When the support shaft 102c is connected to the pad 102c (Fig. 4 (b)), the end of the support shaft 102c is screwed to the pad 102b. In this case, a thread is also formed on the inner peripheral edge of the pad 102b.

When the user rotates the rotary shaft 102 clockwise or counterclockwise in a state where the rotary shaft 102 is mounted on the housing 1 through the screw hole 105a, the rotary shaft 102 rotates in the direction D1 Or D2 direction. That is, the rotating bar 102 can advance or retract toward the fixed electrode 106. [

The pad 102b which is the end of the rotary shaft 102 is positioned adjacent to the flow electrode 107. When the rotary shaft 102 is advanced in the direction D1, the pad 102b is interlocked with the pad 102b and pushes the battery 5 in the direction D1.

Therefore, the distance between the two electrodes (positive electrode or negative electrode) of the battery 5 is reduced, and the battery is in close contact with the fixed electrode 106 and the flowing electrode 107 to be electrically connected.

On the other hand, when the battery 5 is to be detached from the storage area 101, the user retracts the rotating bar 102 in the direction D2. When the rotating bar 102 is retracted in the direction D2, the tension of the spring applied to the battery 5 is reduced, so that the battery 5 can be easily detached from the receiving area 101. [
