In one embodiment of the present invention, the fastening pins 136 are fixed and released by magnetic force. For this purpose, the components provided in the fixing member 139 are made of a metal material. For example, the ball 132, the support member 133 may be formed of a metal material, the fastening pin 136 is preferably made of a non-metal material. If the fastening pin 136 is made of a metal material, when the magnetic member 145 is disposed under the cover 135, the fastening pin 136 is also drawn by the magnetic member 145 so that the fastening pin ( 136) is not easy to disassemble. However, the ball 132 does not necessarily need to be a metal material. Because, when the support member 133 is moved, the ball 132 will move to the support member receiving portion 137, which is a wider space than the receiving groove 131a. However, in order to move the ball 132 more reliably, it is preferable to use a metal material.

holes

105a, 105b, and 105c formed in the fixing member 139, the elastic member 134 may cause the elasticity of the fastening pin 136. The ball 132 is in close contact with the receiving groove 131a, and if the pull pin 136 is pulled out, the fastening pin 136 is caused by the friction force between the ball 132 and the fastening pin 136. It will not be pulled out. In particular, the receiving groove 131a is formed to be inclined toward the withdrawal direction of the ball 132, so that the friction force between the ball 132 and the protrusion 136a becomes larger. That is, the receiving groove 131a extends from the inclined portion 131b and the inclined portion 131b which are inclined toward the first through hole 105a to move while the ball 132 is in contact with each other. It comprises a seating portion (131c). When the ball 132 is seated on the seating portion 131c, the ball 132 is exposed toward the first through hole 105a.

By this process, the ball 132 is released from the receiving groove 131a and positioned in the support member receiving part 137. In this state, the protruding portion 136a of the ball 132 and the fastening pin 136 is not in contact with each other or the friction force does not work even when the contact is in a state that the fastening pin 136 can be easily removed. That is, as shown in Figure 5b and 5c, when the magnetic member 145 is disposed on one side of the cover 135, the support member 133 is lowered while pressing the elastic member 134, the ball 132 is lowered together to reduce the friction provided by the ball 132 to the fastening pin. When the fastening pin 136 is pulled in this state, the fastening pin 136 is easily pulled out even with a small force, and the fastening pin 136 is pulled out through the through

holes

105a, 105b, and 105c. In this case, the support member receiving portion 137 may provide a passage for the support member 133 to move up and down, and the ball 132 may be positioned in the second state. In addition, the upper surface of the support member 133 is formed to be inclined downward toward the outside, in the second state the ball 132 is positioned to the outside of the support member receiving portion 137 and the fastening pin 136 ) To reduce friction. When the jig is removed, the supporting member 133 is returned to its original state by the elastic member 134.
