As the fixed plate 204 flips, the free end of the hinge plate 202 gradually opens. When the hinge plate 202 opens, the rotating shaft 202b-1 rotates along the axial direction of the shaft hole 201b-1; at this time, the torsion spring 202c is in a gradually compressed state; as the end of the fixed plate 204 approaches the first limit block 202e, the limit plate 202a and the side wall of the placement rack 103 become parallel, and as the end of the fixed plate 204 contacts the first limit block 202e, the distance between the two sets of hinge plates 202 is fixed; at this time, the side wall of the connecting rod 203 no longer limits the second limit block 303, and under the action of the rebound force of the spring 305, the second limit block 303 is driven to move to the end side of the connecting rod 203, so that the connecting rod 203 can be limited by the set second limit block 303; thereby ensuring that the limit plate 202a can be close to the side wall of the placement rack 103, so as to fix the position of the horizontal frame 201;

[0059] When the cross frame 201 needs to be disassembled, the knob 304 is pulled, and the knob 304 drives the second limit block 303 to move, so that the second limit block 303 gradually moves away from the end of the connecting rod 203, and the second limit block 303 gradually compresses the spring 305 during the movement; when the second limit block 303 moves to one side of the end of the connecting rod 203; at this time, under the rebound force of the torsion spring 202c, the two sets of hinge plates 202 are driven to rotate along the axis direction of the rotating shaft 202b-1, and as the hinge plates 202 rotate, the ends of the hinge plates 202 gradually move away from the ends of the hinge plates 202. The hinged plates 202 gradually approach each other; while the hinged plates 202 approach each other, they press the fixed plates 204 inwards, so that the fixed plates 204 gradually approach a vertical state; during the flipping process of the fixed plates 204, the connecting rod 203 is pushed to move, so that the connecting rod 203 slides along the inner wall of the circular hole 201c; then, the hand pulling the spring 305 is released; at this time, the two groups of limit plates 202a retract inwardly; the opening angle of the two groups of hinged plates 202 gradually decreases, so that the hinged plates 202 can be taken out from the inside of the mounting hole 103a; and then the disassembly of the cross frame 201 can be completed.

[0060] In summary, the support unit provided can improve the support effect of the cross frame, so that it is better to support more screwdrivers; the locking unit provided can limit the connecting rod, so that the two sets of hinged plates can be relatively unfolded, so that the position of the cross frame can be fixed by unfolding the hinged plates; thereby making it easier for staff to place screwdrivers.
