The size of the insertion rod 211 matches the size of the socket of the fixing block 208. When the staff pulls the operating plate 210, the operating plate 210 slides on the arc surface of the fixing rod 209. At this time, the limit plate 212 achieves the effect of limiting the maximum sliding distance of the operating plate 210 on the arc surface of the fixing rod 209, thereby preventing the staff from pulling the operating plate 211. 0, because the staff can not fully control their operating force, resulting in excessive pulling force when pulling the operating plate 210, causing the operating plate 210 to detach from the arc surface of the fixed rod 209. The arc surface of the fixed rod 209 is covered with a first spring 213, and the two ends of the first spring 213 are fixedly connected to the operating plate 210 and the protective bin 202 respectively. When the staff releases the operating plate 210, the rebound force of the first spring 213 drives the operating plate 210 to slide on the arc surface of the fixed rod 209. At the same time, the operating plate 210 drives the insertion rod 211 to move until the insertion rod 211 is inserted into the socket of the fixed block 208. At this time, the first spring 213 increases the insertion rod 211 against the fixed block. 208 is limited, thereby improving the stability of the protective bin 202 when it is limited as a whole. The arc surface of the rotating rod 205 is covered with two torsion springs 214, and the two ends of the torsion spring 214 are fixedly connected to the L-shaped frame 204 and the connecting plate 206 respectively.

When the staff uses When the palm of the hand holds the portable handle 32, the palm is in direct contact with the anti-slip pad 35. At this time, the anti-slip pad 35 achieves an anti-slip effect, so as to increase the friction between the portable handle 32 and the palm of the staff, and improve the stability of the staff when using the portable handle 32. Two anti-pinch rings 36 are fixedly connected to the side of the portable handle 32 away from the anti-slip pad 35. The anti-pinch ring 36 is slidably connected to the arc surface of the screw 33. When the staff holds the portable handle 32, the anti-pinch ring 36 will remind the staff whether the palm gripping position is correct, thereby preventing the staff from pinching the hand when adjusting the height of the portable handle 32.

[0032] Working principle: when the circuit board body 1 is idle or being transported, the staff needs to protect the circuit board body 1. At this time, the operating plate 210 is pulled to make the operating plate 210 slide on the arc surface of the fixed rod 209. The first spring 213 is stretched, and at the same time, the operating plate 210 drives the insertion rod 211 to move until the insertion rod 211 no longer blocks the circuit board body 1 from entering the protective bin 202. At this time, the protective bin 202 is pushed to make the protective bin 202 slide in the U-shaped frame 201. At the same time, the protective bin 202 drives the L-shaped plate 203 to slide on the lower surface of the circuit board body 1 until the protective bin 202 completely covers the circuit board body 1.

At this time, the circuit board body 1 is dustproof, waterproof and collision-proof, which prevents the circuit board body 1 from being affected by dust, liquid or external hard objects during idleness or transportation, resulting in damage to the circuit board body 1, which makes the circuit board body 1 unable to be used normally and wastes resources and costs, thereby improving the protection of the device.

[0033] When the staff needs to carry the circuit board body 1 with them, they rotate the support block 34, and the support block 34 moves on the arc surface of the screw rod 33. At the same time, the support block 34 drives the carrying handle 32 to slide on the arc surface of the screw rod 33, and the carrying handle 32 slides on the surface of the square block 31 until the height of the carrying handle 32 meets the staff's needs. At this time, the staff holds the carrying handle 32 with their palms, and the staff's palms directly fit into the anti-slip pad 35. The carrying handle 32 is pulled to drive the protective compartment 202 to move, and the protective compartment 202 drives the circuit board body 1 to move. At this time, the effect of making it convenient for the staff to carry the circuit board body 1 safely and easily is achieved, and the effect of adjusting the gripping space according to the size of the staff's palm is achieved, avoiding the situation where there is no suitable gripping point on the circuit board body 1 or the protective compartment 202 when the staff needs to carry the circuit board body 1 with them, causing the staff to have to hug or clamp their hands under their armpits, thereby increasing the staff's workload and improving the staff's work efficiency.
