When the slider 1107 moves to the right side, the second pull rope 1302 is driven to move to the right side, the second pull rope 1302 drives the rack frame 1303 to move upwards through the guide wheel 1301, the fourth spring 1304 deforms, the rack frame 1303 drives the second gear 1306, the third rotating shaft 1305 and the bevel gear 1307 to rotate forwards, the bevel gear 1307 drives the fourth rotating shaft 1308, the transmission wheel 1309, the belt 1310 and the first reel 1203 to rotate forwards, the first reel 1203 drives the rubber belt 1205 and the protective screen 1206 to move to the left side through the guide roller 1204, the protective screen 1206 is opened, medical staff can conveniently store and take the medical staff, the protective screen 1206 drives the first pull rope 1211 to move to the left side, the first pull rope 1211 drives the second reel 1210 and the rotating rod 1208 to rotate forwards, the spring 1209 deforms, when the slider 1107 moves to the left side, the rack frame 1303 is driven to move downwards to reset under the reset action of the fourth spring 1304, the rack frame 1303 can drive the second gear 1306, the third rotating shaft 1305 and the bevel gear 1307 rotate reversely, the bevel gear 1307 can drive the fourth rotating shaft 1308, the transmission wheel 1309, the belt 1310 and the first reel 1203 rotate reversely, because under the reset action of the clockwork spring 1209, the second reel 1210 and the rotating rod 1208 rotate reversely, thereby the second reel 1210 can drive the first pulling rope 1211 and the protection net 1206 to move to the right side to reset, under the action of the protection net 1206, so that the movable frame 404 and the articles placed in the frame 402 can not fall, and the operation convenience of medical staff is improved.

The locking assembly 14 comprises a clamping block 1401, a fifth spring 1402 and a wedge block 1403, the clamping block 1401 is arranged in the middle of the fixing frame 1102 in a sliding mode, the fifth spring 1402 is symmetrically connected between the clamping block 1401 and the fixing frame 1102, the fifth spring 1402 is sleeved on the clamping block 1401, the wedge block 1403 is arranged on the top of the right rotating plate 1101 in a sleeving mode, and the wedge block 1403 is matched with the clamping block 1401.

When the right side changes board 1101 and upwards moves, can drive wedge 1403 and move, when wedge 1403 and fixture block 1401 contact, can drive fixture block 1401 rebound, fifth spring 1402 takes place deformation, when wedge 1403 cooperates with fixture block 1401, because under the reset action of fifth spring 1402, can drive fixture block 1401 rebound, thereby block wedge 1403, make medical personnel need not spur handle 1104 always, operation is convenient, when medical personnel upwards move fixture block 1401, the fixture block can break away from with wedge 1403, thereby change board 1101 and drive wedge 1403 rebound to reseing.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
