when the first clamping plate 6 and the second clamping plate 7 respectively abut against two side edges of the display screen, namely the display is clamped and fixed between the first clamping plate 6 and the second clamping plate 7, the pushing assembly 13 pushes the moving block 11 to move towards the side close to the limiting plate 3 under the action of the driving mechanism 9, so that a wiring socket of the display is in electric signal connection with the contact end 12, on the contrary, when the display is not fixed by the first clamping plate 6 and the second clamping plate 7, the moving block 11 can move reversely to the side far away from the display under the action of the pushing assembly 13, so that the electric signal connection of the display is released, and the contact switch 4 is firstly released when the contact end 12 is driven by the moving block 11 to leave the display, and at the moment of releasing, the contact end 12 is not pulled out from the socket of the display, so that the power is firstly cut off and the signal is cut off, and the whole process cannot cause damage to the display;

a release member 14 disposed on the driving mechanism 9 for manual operation, which is used to release the working state of the driving mechanism 9, i.e. when it is otherwise triggered, the driving mechanism 9 will stop applying the clamping force to the first clamping plate 6 and the second clamping plate 7, so as to separate the two, after the two are separated, the supply of the display signal to the display is naturally released by the action of the pushing member, and then the display can be directly removed;

therefore, an overall usage flow is that, a display is placed on the bearing surface 2, the display side faces upwards, the side with a port on the display faces towards the moving block 11, and the whole display is completely placed in the area between the two limiting plates 3, so that after the contact block 10 is pressed down by the gravity of the display, the driving mechanism 9 starts to work, so that the first clamping plate 6 and the second clamping plate 7 are close to each other to clamp and fix the display, then the moving block 11 moves under the action of the pushing assembly 13 to realize the electrical conduction of the display, so that the display is automatically turned on, here, referring to fig. 7, fig. 7 is an effect diagram when the display is clamped, namely, in the whole process, after the display is placed on the bearing surface 2, the display is automatically fixed and is automatically turned on, so that whether the display is abnormal or not can be directly observed, after the detection is finished, the release piece 14 is manually touched, so that the first clamping plate 6 and the second clamping plate 7 are separated from each other, the display is automatically turned on, so that whether the display is abnormal or not abnormal display, and a great amount of time is saved when the detection is finished, so that the detection of the whole hospital is directly detected, and the detection of the whole connection of the hospital, and the hospital is improved, so that the whole connection of the hospital, the hospital can be more, and the hospital, the whole detection efficiency is improved, and the hospital can be more, and the hospital can be detected more, and the hospital.

As shown in fig. 1 to 3, in some embodiments, the connecting mechanism 5 integrally includes an upper swing frame 501, a lower swing frame 502, an upper push frame 503 and a lower push frame 504, and since the two connecting mechanisms 5 are integrally symmetrically designed and accomplish the same, one of them is described here, where:

the lower swing frame 502 is hinged with the lower push frame 504;

taking the perspective of fig. 3 as an example, the connection mode is such that the whole forms a parallelogram structure, so that the parallelogram structure has the motion property of the fork, when the lower swing frame 502 moves, the first clamping plate 6 or the second clamping plate 7 moves horizontally, but the motion route is not horizontal, the first clamping plate 6 is taken as an example, when the lower swing frame 502 moves clockwise, the first clamping plate 6 is carried out to move towards the right side, namely towards the display placing position, when moving, the first clamping plate 6 also carries out clockwise motion with a small amplitude, so that when contacting the side edge of the display, the display has a horizontal downward force, so that the display is fixed and can be more stable, and when moving away, the first clamping plate 6 also moves obliquely upward.

As shown in fig. 3, in some embodiments, the height of the support surface 2 is located at the middle of the vertical height of the first and

second clamping plates

6 and 7, so that when the monitor is placed on the support surface 2 and the first and

second clamping plates

6 and 7 contact both sides of the monitor, the side of the monitor is located at the middle of the first and

second clamping plates

6 and 7, which makes the monitor more stable when the first and

second clamping plates

the other end of the hinged block 9038 is fixedly connected with the driving rod 23, and as one hinged position of the inclined rod 9037 and the sliding rod 9035 can only do linear motion, when the sliding block slides, the connecting position of the inclined rod 9037 and the hinged block 9038 moves, so that the driving rod 23 is rotated;

compared with the design of the first embodiment, in this embodiment, the first push rod is specifically designed in a vertical direction, so that the piston rod moves downward when working, and the overall working process is that when the piston rod works, it moves downward, the sliding rod 9035 is moved linearly through the action of the hinge rod 9036, so that the hinge block 9038 is pushed to swing through the inclined rod 9037, so as to push the driving rod 23 to move.
