[0022] During operation, the existing automatic lifting bracket for glass liquid thermometer can only simply fix the glass liquid thermometer when in use. When people coming and going in the vegetable greenhouse carry out transportation operations, unpredictable collisions will occur to the thermometer, causing the glass liquid thermometer to be easily broken. The present application acts through an auxiliary positioning device to insert the thermometer rod body 413 to be positioned into the positioning groove 409 at the bottom of the positioning cavity 402. Under the action of the elastic clamping plate 410, auxiliary positioning of the bottom of the thermometer is achieved, and the elastic rod 412 on the fixing rod 411 is inserted into the structural ring at the top of the thermometer to avoid the tendency of the thermometer to move up and down.

[0024] During operation, according to the operating height of the thermometer, the retracting mechanism 416 is rotated so that the measuring tape 415 of a specified length extends from the inside of the fixed box 414. With the cooperation of the lifting mechanism 3, the lifting frame 401 moves to a suitable position so that the starting end of the measuring tape 415 is just in contact with the bottom structure of the fixed bracket 1, thereby achieving the effect of positioning and installing the glass liquid thermometer.

Under the action of the elastic splint 410, the auxiliary positioning of the bottom of the thermometer is achieved, and the elastic rod 412 on the fixing rod 411 is inserted into the thermometer. The structural ring at the top of the thermometer avoids the tendency of the thermometer to move up and down. Then, a rotational force is applied to the rotating button 408 on the lifting frame 401, the screw 404 rotates, and the moving block 405 drives the clamping plate 406 to move toward each other along the sliding rod 403.

With the cooperation of the lifting mechanism 3, the lifting frame 401 moves to a suitable position, so that the starting end of the tape measure 415 is just in contact with the bottom structure of the fixed bracket 1, thereby achieving the effect of positioning and installing the glass liquid thermometer.
