[0025] Working principle: When wearing the guard plate 1, first wrap the strap 9 around the user's arm, and pass the other end of the strap 9 around the outside of the installation frame 8, adjust the tightness of the strap 9, and stick the hook surface Velcro 11 to the suede Velcro 10. At this time, the guard plate 1 is worn. After the guard plate 1 is worn, each mounting plate 314 is pulled outward, which can drive the insertion rod 315 to move outward, so that the insertion rod 315 moves out of the slot 316. When the mounting plate 314 moves outward, it can drive the connecting rod 311 to move, and then drive the hexagonal head 31 0 moves in the direction of the mounting plate 314. When the hexagonal head 310 moves to the annular groove 309, the mounting plate 314 is rotated, and then the hexagonal head 310 can be driven to rotate through the connecting rod 311. Due to the setting of the rotating ring 312, when the hexagonal head 310 rotates, the push spring 313 will not produce motion interference. At this time, the hexagonal head 310 is engaged with the annular groove 309, and then the push spring 313 can be compressed, and the hexagonal head 310 can be prevented from driving the connecting rod 311 to move into the inside of the hexagonal groove 308. At this time, the insertion rod 315 and the slot 31 are released. 6 is engaged, and then the rotating base 303 can be rotated on the rotating sleeve 302, the rotating box 304 can be rotated on the rotating base 303, and the connecting plate 307 can be rotated on the inner plate 306.
