Figure 8 As shown, the hinge cover 1 rotates around the hinge axis. When the hinge cover 1 rotates to the second position, the shift block 22 rotates in the opposite direction, and the pawl piece 21 rotates in the opposite direction synchronously. The bottom of the pawl piece 21 is clamped to the bottom of the other side of the hinge cover 1, as shown in FIG. Fig.10 As shown, locking is completed; when it is necessary to reset, the shift block 22 is rotated, the pawl piece 21 rotates synchronously, the bottom of the pawl piece 21 is disengaged from the bottom of the other side of the hinge cover 1, and the hinge cover 1 rotates around the hinge axis. When the hinge cover 1 is rotated to the first position, the shift block 22 is rotated in the opposite direction, the pawl piece 21 rotates in the opposite direction synchronously, and the bottom of the pawl piece 21 is engaged with the middle of the other side of the hinge cover 1, as shown in FIG. Figure 7 and Fig. 9 As shown, locking is completed; the operation is easy, the locking structure is simple, and locking and unlocking are easy to control.
