screen in the groove 85 so as to be abutted and fixed with one side of the display screen, the lower pressing plate 3 continuously drives the probe 4 and the sleeve 5 to move downwards, the descending of the sleeve 5 can enable the limiting rod 10 to continuously slide and contact with the curved groove 51, the sleeve 5 is driven to rotate in the process that the limiting rod 10 slides along the curved groove 51, when the limiting rod 10 slides to the tail end of the curved groove 51, the limiting rod 10 does not drive the sleeve 5 to rotate, the sleeve 5 is rotated to finish, in the process, the probe 4 can be cleaned outside through the rotation of the sleeve 5, but in the state, the sleeve 5 still wraps the probe 4 in the process, if the probe 4 is required to be used for burning the display screen at the moment, the sleeve 5 needs to be manually moved upwards along the probe 4, the sleeve 5 can be driven to move upwards along the direction of the rotating groove 31 so as to compress the first spring 11, in this step, when the limit rod 10 slides to the tail end of the curve groove 51, the lower pressure plate 3 and the sleeve 5 can be continuously moved downwards, the sleeve 5 and the rotating plate 12 can be driven to move upwards along the rotating groove 31 by the abutting action of the limit rod 10, so that the probe 4 can leak out to conveniently detect the display screen, because the first spring 11 is not fixedly connected with the rotating plate 12, the rotation of the rotating plate 12 driven by the previous sleeve 5 cannot be influenced, the sleeve 5 can be driven to rotate to clean the probe 4 in the descending process of the lower pressure plate 3, the lower pressure plate 3 can be continuously descended to drive the sleeve 5 to move upwards, the probe 4 can leak out to conveniently burn the display screen, the operation is convenient, only the lower pressure plate 3 needs to be moved downwards, and meanwhile, the rotation of the sleeve 5 drives the lower pressure rod 17 to rotate, the height of the lower pressure rod 17 is also lowered while rotating, so that the initial height of the lower pressure rod 17 is higher than the height of the movable plate 14, when the sleeve 5 stops rotating, the lower pressure rod 17 is positioned right above the movable plate 14 and a small distance is reserved between the lower pressure rod and the movable plate, the sleeve 5 is driven to move upwards by the action of the limiting rod 10 to enable the probe 4 to leak, the lower pressure plate 3 continuously moves downwards to drive the sleeve 5 to move upwards to enable the probe 4 to leak, then the lowering of the lower pressure plate 3 is normally stopped, the burning operation is carried out on the display screen through the probe 4, but if the distance between the probe 4 and the display screen is controlled inaccurately by an operator, the lower pressure plate 3 is continuously moved downwards, the lower pressure plate 3 drives the lower pressure rod 17 to move downwards, although the sleeve 5 moves upwards relative to the probe 4 in the process, the sleeve 5 moves upwards to drive the down-pressing rod 17 to move upwards, but the ascending speed of the sleeve 5 is smaller than the descending speed of the down-pressing plate 3, finally, the down-pressing rod 17 moves downwards to drive the moving plate 14 to move downwards to drive the object placing plate 7 and the display screen to move downwards, so that the distance between the object placing plate 7 and the probe 4 is increased, in addition, the down-pressing rod 17 moves downwards to drive the moving plate 14 and the lifting rod 15 to move downwards to enable the object placing plate 7 to move downwards, the fixed block 81 and the rotating rod 83 are driven to move downwards by the descending of the object placing plate 7, the moving rod 83 is driven to move downwards along the notch 62 by the descending of the rotating rod 83, the limiting block 20 is made of elastic materials, in an initial state, the limiting block 20 is in a compressed state and is in contact with the inside of the notch 62, when the rotating rod 83 moves downwards to drive the moving block 19 to move downwards to the position of the limiting hole 18, the abutting acting force of the inner wall of the limiting block 20 and the limiting hole 18 is eliminated, at the moment, the rotating rod 83 cannot move downwards, the rotating rod 83 cannot move continuously, the object placing plate 7 cannot descend continuously, the probe 7 cannot descend continuously, the distance between the object placing plate 7 and the probe 4 cannot be lowered continuously, and the distance between the probe 4 cannot be kept continuously, and the object placing plate cannot be lowered continuously, and the probe 4 cannot be lowered, and the distance cannot be kept continuously, and the distance between the moving rod and the probe can be lowered continuously, and the probe can be lowered, and the display panel can be lowered continuously, and the distance can be lowered.
