[0032] Reference Figure 1 - Figure 5 The utility model provides an embodiment of a city layout display device, comprising two support tables 1, which are slidably connected to each other. The support tables 1 are used to place and support a sand table 10. The two support tables 1 slide crosswise. A slide bar 2 is fixedly connected to the inner side of the two support tables 1 toward the side away from each other. A spring 3 is sleeved on the outer side of the slide bar 2. A push rod 4 is fixedly connected to the outer side of the spring 3. The top of the push rod 4 is rotatably connected to a rotating rod 5. The outer side of the rotating rod 5 is slidably connected to a sleeve rod 6. The inner side of the sleeve rod 6 is slidably connected to a rotating rod 2 7. The top of the rod 2 7 is rotatably connected with an insertion rod 9, and the inside of the insertion rod 9 is slidably connected with a slide rod 2 8. The slide rod 1 2 is used to limit the movement direction of the push rod 4 to ensure that the handle 17 can only move left and right and will not move around. The spring 1 3 is used to drive the push rod 4 to reset. The push rod 4 is used to facilitate manual pressing to drive the rotating rod 1 5 to deflect. The rotating rod 1 5 is used to drive the sleeve rod 6 to rotate and at the same time drive the rotating rod 2 7 to deflect. The rotating rod 1 5 and the rotating rod 2 7 both slide inside the sleeve rod 6. The insertion rod 9 is to be inserted into the inside of another support table 1 to lock the support table 1. The outer side of the sliding rod 8 is fixedly connected to the inside of the support table 1, ensuring that the sliding rod 2 8 remains stable and limits the movement of the insertion rod 9. The outer side of the insertion rod 9 passes through the inner side of one of the support tables 1 and is inserted into the inner side of the other support table 1 to achieve size change and lock.

[0033] Reference Figure 1 - Figure 5The fixing assembly includes multiple inner shells 11, the outside of the inner shell 11 is fixedly connected to the inside of the supporting table 1, the inner wall of the inner shell 11 is fixedly connected with a spring 2 12, the inside of the spring 2 12 is fixedly connected with a baffle 13, the inside of the baffle 13 is fixedly connected with a fixing plate 14, and the top of the fixing plate 14 is fixedly connected with a pull rod 15. The inner shell 11 is used to connect and protect internal parts, the spring 2 12 is used to push the baffle 13 to move, the baffle 13 is used to withstand the thrust from the spring 2 12 and drive the fixing plate 14 to move, the fixing plate 14 is used to block the sandbox 10 and fix the sandbox 10, the pull rod 15 is used to facilitate manual pressing of the fixing plate 14 to move, the outside of the baffle 13 is slidably connected to the inner wall of the supporting table 1, the outside of the fixing plate 14 is slidably connected to the inside of the inner shell 11, and the fixing plate 14 is slidably connected to the top edge of the sandbox 10, and the inner shell 11 limits the moving direction of the baffle 13 and the fixing plate 14 to ensure that it can only move left and right and block the top of the sandbox 10.

[0034] Working principle: When the sand table 10 needs to be displayed, the size of the support table 1 is first changed according to the size of the sand table 10, and the handle 17 is pressed to drive the push rod 4 to move. Under the limit of the slide bar 2, the spring 3 is compressed, and the rotating rod 15 is driven to deflect the sleeve rod 6, and at the same time, the rotating rod 2 is driven to move. Under the limit of the slide bar 2 8, the insertion rod 9 is moved outward to achieve unlocking. At this time, the support table 1 is pulled and adjusted to the appropriate position according to the size of the sand table 10. Then, the handle 17 is released. Under the action of the slide bar 2, the push rod 4 is pushed, and the rotating rod 15 is driven to make the sleeve rod 6 reverse. Rotate in the direction to let the rotating rod 2 7 push the insertion rod 9 to reset, reinsert it into the support table 1 and lock it, then move the pull rod 15 to drive the fixed plate 14 to move outward, so that the baffle 13 compresses the spring 2 12. At this time, place the sand table 10 between the two support tables 1, and then release the pull rod 15. Under the limit of the inner shell 11, the spring 2 12 pushes the baffle 13 to move, so that the fixed plate 14 is reset and blocked at the top edge of the sand table 10 to achieve fixation. When replacing, you only need to press the fixed plate 14 into the inner shell 11 to remove and replace the sand table 10.
