The second guide rod 13 moves upwards to drive the second rack 113 to move upwards, the second rack 113 moves upwards to drive the gear 112 to rotate anticlockwise, the gear 112 rotates anticlockwise to drive the first rack 111 to move downwards, so that the support plate 8 is driven to move downwards, and the roller 10 can be moved out of the second groove 6; when the box body 1 moves downwards, the box body 1 drives the gear 112 to move downwards, the gear 112 rolls on the first rack 111, the gear 112 rotates clockwise, the second rack 113 is driven to move downwards, when a user pushes the first slide bar 15 to move downwards to be in contact with the first slide hole 14 through the second handle 16, the second guide rod 13 drives the second rack 113 to continue to move downwards, the gear 112 can drive the first rack 111 to move upwards to drive the support plate 8 to move upwards, the support plate 8 moves upwards to retract the roller 10 into the second groove 6, the second slide bar 20 is clamped in the corresponding first clamping groove 17, and then the positions of the support plate 8 and the roller 10 can be fixed.
The first slide bar 15 moves upwards to enable the second clamping wheel 30 to be separated from the third clamping groove 31, the first spring 29 is stretched, when the first slide bar 15 moves upwards to be in contact with the fixed block 131, the second clamping wheel 30 is clamped in the fourth clamping groove 32 through the third guide rod 27 under the action of the first spring 29, the first slide bar 15 is further fixed, the first slide bar 15 is prevented from sliding into the first sliding hole 14 when a user loosens the second handle 16, the first slide bar 15 needs to be pulled out of the first sliding hole 14 again when the user needs to move, and therefore abrasion of the first slide bar 15 can be reduced.
When the user need close apron 2, the user alright promote slider 35 downstream, second spring 37 is compressed, afterwards through rotating apron 2, apron 2 drives in the hook 33 upward movement and the immigration is in first recess 4, close the back when apron 2, unclamp slider 35, under the effect of second spring 37, make slider 35 rebound catch hook 33, thereby fix apron 2, so can avoid being equipped with in the box 1 when enough instruments, apron 2 can not opened.
When the first handle 102 is not needed to be used, a user can push the first handle 102 to swing rightwards, so that the first handle 102 is located in the slotted hole 101, the third sliding rod 40 drives the third clamping wheel 42 to move rightwards, the third spring 41 is compressed, the third clamping wheel 42 is clamped in the fifth clamping groove 38, and therefore the first handle 102 is fixed, and the first handle 102 is prevented from being damaged due to the fact that the first handle 102 swings freely and collides with the box body 1 in the moving process.
