[0042] Connection between the box body and the base: the bottom end of the rack is connected to the base.

[0043] 1. The implementation process of placing protective armor into the rack:

[0044] Pull the movable hook (8) upward, put the protective armor (10) into the fixed hook (7), and move the movable hook (8) downward to hook the protective armor (10). Turn the two knobs of the fixer (9) to lock in the left and right directions, so that the protective armor (10) is fixed to the storage rack (1).

[0045] 2. The process of moving the device to the working position:

[0046] Pull the pull rod (28) on the base (3) to drive the entire device to the working position, and use the wheel fixer on the wheel (27) to fix the position.

[0047] 3. The process of increasing the height:

[0048] The height crank (18) is rotated counterclockwise, and the height ratchet (20), pinion 1 (21) and the height crank (18) rotate coaxially, pinion 1 (21) and large gear 2 (22) are gear-driven, pinion 2 (23) and large gear 2 (22) are coaxially rotated, pinion 2 (23) and rack (24) are driven, rack (24) and rack track (25) move relative to each other, and since rack (24) is connected to base (3), it remains stationary with the earth in the height direction, and rack track (25) moves upward. The rectangular shell (11) in the box (2) is connected to rack track (25), and the box (2) moves upward as a whole to increase the height. The height ratchet (20) is limited to unidirectional movement, thereby preventing the box (2) and the storage rack (1) from falling due to gravity. The bottom end of rack (24) is "convex" shaped, which can play a limiting role at the maximum height.

[0049] 4. The process of realizing the rotation angle:

[0050] The angle crank (12) is rotated counterclockwise, and the angle ratchet (14), the large gear one (15) and the angle crank (12) rotate coaxially, and the large gear one (15) and the toothed arc plate (16) are transmitted. The toothed arc plate (16) is connected to the flat plate (4) in the storage rack (1), and the storage rack (1) rotates at an angle. The angle ratchet (14) is limited to unidirectional movement, thereby preventing the storage rack (1) from falling due to gravity. The two sides of the tail of the toothed arc plate (16) are raised, and the width is greater than the width of the rectangular hole on the front side of the rectangular shell (11), which can play a role in limiting the maximum angle.

[0051] 5. The process of realizing the rotation angle during recycling:

[0052] Pressing the pressure rod 1 (13), the pressure rod 1 (13) is connected to the spring of the angle ratchet (14), and the spring releases the locking claw of the angle ratchet (14), thereby releasing the one-way limit of the angle ratchet (14). The angle crank (12) is rotated clockwise, and the rack (1) is rotated back to the initial angle through the transmission of the large gear 1 (15) and the gear arc plate (16).

[0053] 6. The process of reducing the height during recycling:

[0054] Press down the second pressure rod (19), the second pressure rod (19) is connected to the spring of the height ratchet (20), and the spring is released to release the locking claw of the height ratchet (20), thereby releasing the one-way limit of the height ratchet (20). The height crank (18) is rotated clockwise, and through the transmission of the small gear (21) and the large gear (22), the small gear (23) and the rack (24), the rack (24) and the rack track (25) move relative to each other, and the rack track (25) moves downward. The rectangular housing (11) in the box body (2) is connected to the rack track (25), and the box body (2) moves downward as a whole to reduce the height.
