[0027] During use, through the setting of the spring 17, a downward elastic pressure can be applied to the activity block 4;

[0028] Limit blocks 13 are movably installed on the outer walls of the side frame body 3 at the position of the activity block 4. One end of the limit block 13 penetrates through the waist-shaped limit groove 12 and touches the outer wall of the activity block 4. Two positioning pins 14 are provided on the outer walls of the limit blocks 13. One end of the positioning pin 14 penetrates through the limit block 13 and is connected to the outer wall of the activity block 4. A bearing seat 6 is provided on the inner wall between the activity blocks 4. At the center position of the top end of the bearing seat 6, a butting seat 5 is provided.
