The shaft 710 and the second slide shaft 720 are fixed to the lower ends of the third guide groove 651 and the fourth guide groove 661.

As shown in FIG. 14, as the cover 300 rotates to move the first slide shaft 710 and the second slide shaft 720 in contact with the cam surface 630, the friction member 900 may be formed. The first slide shaft 710 and the second slide shaft 720 respectively move in the opposite directions to compress the elastic member 800.

Subsequently, as shown in FIG. 15, when the first slide shaft 710 and the second slide shaft 720 pass the maximum bending point of the cam surface 630, the first elastic shaft 800 causes the first movement. The slide shaft 710 and the second slice shaft 720 automatically move to the top of the third guide groove 651 and the second guide groove 661.

As such, by inserting the elastic member 800 and the friction member 900 in the guide member 600, there is an effect that can increase the elastic force of the elastic member (800).
