[0035] Please refer to Figure 8As shown, the clamping assembly 8 comprises a slot group opened on the two sides of the inner wall of the storage box 5, the slot group comprises grooves 801 arranged uniformly along the height direction of the storage box 5 and second connecting holes 12 communicated between each groove 801, the second chamber 502 is communicated with the groove 801 through the first connecting hole 11, the inside of the groove 801 is provided with a third piston 802, and the third piston 802 is connected with the inner side wall of the groove 801 through a second spring 803, and the side of the third piston 802 away from the second spring 803 is provided with a clamping plate 804 penetrating to the outside of the groove 801; the inner bottom of the second chamber 502 is provided with a third spring 10, the top of the third spring 10 is provided with a fourth piston 9, and the fourth piston 9 is connected with the placement plate 7 through a support rod; in use, after the demonstration appliance is placed on the placement plate 7, the placement plate 7 is appropriately pressed down, so that the placement plate 7 drives the fourth piston 9 to descend and compress the third spring 10, the descent of the fourth piston 9 can make the air below the fourth piston 9 enter the inside of each groove 801 through the first connecting hole 11 and the second connecting hole 12, and make the third piston 802 in the groove 801 drive the clamping plate 804 to move towards the demonstration appliance, so that the demonstration appliance is clamped; it should be noted that the elastic coefficient of the third spring 10 and the specific volume size of the groove 801 and the second chamber 502 can be appropriately adjusted according to the actual use of the demonstration appliance; at the same time, a corresponding protection pad can be arranged on the clamping plate 804, so as to further protect the demonstration appliance, and the use effect is better.

[0036] Please refer to Figure 8 and Figure 9 As shown, the locking assembly 14 comprises a third chamber 141 opened in the inside of the storage box 5 and located below the second chamber 502, the four corners in the inside of the third chamber 141 are provided with connecting blocks 142, the inside of the connecting block 142 and the inside of the storage box 5 are both provided with branch holes 143 for communication between the inside of the connecting block 142 and the first connecting hole 11, the inside of the connecting block 142 is also provided with a connecting cavity 144 communicated with the branch hole 143, the inside of the connecting cavity 144 is provided with a fifth piston 145, and one end of the fifth piston 145 away from the branch hole 143 is provided with a connecting rod 146 extending to the outside of the connecting cavity 144, the end of the connecting rod 146 is connected with an electromagnet 147, and every two oppositely arranged electromagnets 147 are magnetically attracted to each other; the unlocking assembly 15 comprises two push plates 151 arranged in the inside of the third chamber 141, the side edges of the two push plates 151 are slidably connected with the side edges of the connecting block 142, the opposite ends of the two push plates 151 are connected through a connecting rod 152, one of the two push plates 151 is connected with the inner side wall of the third chamber 141 through a fourth spring 154, the other push plate 151 is connected with a handle 153 penetrating to the outside of the storage box 5 at one end away from the connecting rod 152, the connecting rod 152 is provided with a trigger key 156, the inside of the third chamber 141 is also provided with a switch 155 matched with the trigger key 156, and the switch 155 and the electromagnet 147 are electrically connected.

[0037] When the fourth piston 9 is lowered by the placing plate 7, the air below the fourth piston 9 can also enter the inside of the connecting cavity 144 through the first connecting hole 11 and the branch hole 143 when the air below the fourth piston 9 enters the inside of the groove 801 through the first connecting hole 11 and the second connecting hole 12, so that the fifth piston 145 inside the connecting cavity 144 drives the connecting rod 146 and the electromagnet 147 to move towards the outside of the connecting block 142, as shown in the figure. Figure 8 As shown in the figure, the two electromagnets 147 on the left side will approach each other until they contact, and the two electromagnets 147 on the right side will also approach each other until they contact, thereby making the fifth piston 145 unable to return to the original position, so that the fourth piston 9 cannot return to the original position, ensuring that the placing plate 7 is always in the low end position, thereby facilitating the demonstration appliance to be always inside the storage box 5;

[0038] When the demonstration appliance needs to be taken out from the inside of the storage box 5, the handle 153 can be pressed, the handle 153 drives the push plate 151 to move towards the deep part of the second cavity 502 and compresses the fourth spring 154, so that the trigger key 156 on the connecting rod 152 contacts the switch 155, the switch 155 makes the electromagnet 147 lose power, at this time the second spring 803 inside the groove 801 and the third spring 10 below the fourth piston 9 will return to the original position, thereby making the clamping plate 804 and the demonstration appliance separate, and the placing plate 7 will rise and drive the demonstration appliance to rise, thereby facilitating the demonstration appliance to be taken out;

[0039] In addition, it is worth mentioning that after the placing plate 7 in the storage box 5 moves to the lowest end, the space above it that can be stored is only slightly larger than the height of the demonstration appliance that needs to be stored, so that after the unlocking assembly 15 unlocks the placing plate 7 and completely rises, the demonstration appliance will be exposed from the storage box 5, thereby making it more convenient for people to take out the demonstration appliance and use it more conveniently.

[0040] Please refer to Figure 8 As shown in the figure, the top of the clamping plate 804 is provided with a guide plate 13, and the longitudinal section of the guide plate 13 is arc-shaped structure, through the guide plate 13, the demonstration appliance can be placed into the inside of the first cavity 501 more conveniently, and the use effect is good.

[0041] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
