The right surface of the round rod 53 is fixedly connected with a pull ring 52.

[0038] Reference Figure 1 - Figure 3The L-shaped groove 301 is opened on the lower surface of the support plate 1. The L-shaped groove 301 is opened in an L shape. The handle 42 is fixedly connected to the upper surface of the slide plate 41. The slide plate 41 and the handle 42 will move synchronously. The handle 42 passes through and is slidably connected to the upper surface of the support plate 1. The front surface of the stopper 44 is set as an inclined surface. The inclined surface of the stopper 44 is squeezed, and the stopper 44 moves upward. The stopper 44 is clamped on the front side of the card block 33, which can limit the card block 33 to ensure the stability of the position of the display board 31. The slide plate 41 is slidably connected to the inner wall of the support plate 1. One end of the compression spring 43 is fixedly connected to the upper surface of the slide 41, and the other end of the compression spring 43 is fixedly connected to the inner wall of the top end of the support plate 1. When the slide 41 slides upward, it will squeeze the compression spring 43 to generate a reaction force. The display board 31, the block 33, the pull buckle 32, and the stopper 44 are provided in two groups, and the L-shaped groove 301 is opened in two groups. The two groups of L-shaped grooves 301, the display board 31, the block 33, the pull buckle 32, and the stopper 44 are arranged in a circular array with the center point of the slide 41. The two groups of display boards 31 are opened from the left and right sides of the support plate 1.

[0039] Reference Figure 1 、 Figure 4 、 Figure 5 The right end of the supporting leg 51 is rotatably connected to the left surface of the supporting plate 1, one end of the limiting spring 55 is fixedly connected to the inner wall of the right side of the supporting plate 1, and the other end of the limiting spring 55 is fixedly connected to the right surface of the round block 54, and the round block 54 is slidably connected to the inner wall of the supporting plate 1. When the round block 54 moves to the right, it will squeeze the limiting spring 55 to produce a reaction force, and the round rod 53 passes through and is slidably connected to the right surface of the supporting plate 1. The round rod 53 is inserted into the inner wall of the limiting groove 502, and the limiting block 56 is inserted into the inner wall of the limiting groove 502. When the round rod 53 moves to the right, it will drive the limiting block 56 to move to the right, and the limiting block 56 moving to the right will be disengaged from the limiting groove 502 to release the limit on the supporting leg 51, and two groups of fixing components are provided, which are symmetrically distributed left and right with the center line of the supporting plate 1.

[0040] Working principle: When using this device, first place the support plate 1 at the designated location, then pull the pull ring 52 to drive the round rod 53, the round block 54, and the limit block 56 to move toward the left and right sides of the support plate 1. When the round block 54 moves, it squeezes the limit spring 55 to generate a reaction force. When the limit block 56 and the round rod 53 move, they will disengage from the limit groove 502 to release the limit on the support leg 51, so that the support leg 51 can be rotated open. When the support leg 51 is rotated open, the protrusion on the limit groove 502 will engage with the limit block 56. After alignment, release the pull ring 52, and the reaction force of the limit spring 55 will push the pull ring 52, the round rod 53, the round block 54, and the limit block 56 toward the middle of the support plate 1. The round rod 53 and the limit block 56 will be plugged into the limit groove 502, and the limit block 56 will be inserted into the protrusion on the limit groove 502 to limit the support leg 51 to ensure stability. At this time, parts such as fixing piles or expansion bolts can be installed on the fixing holes 501 to complete the fixation of the support leg 51 and the ground to ensure the stability of the device.

[0041] Then, the pull buckle 32 is moved to the left and right sides to drive the display board 31 and the block 33 to move synchronously. When the block 33 moves to the left and right edges of the L-shaped groove 301, and then moves in the front and back directions, the block 33 will squeeze the inclined surface of the block 44, and the block 44 will drive the slide plate 41 to move upward. The upward-moving block 44 will release the blockage, and the upward-moving slide plate 41 will squeeze the compression spring 43 to generate a reaction force. When the block 33 moves to the edge of the L-shaped groove 301, the squeezing of the block 44 will be released, and the reaction force of the compression spring 43 will push the slide plate 41 and the block 44 to move downward. The downward-moving block 44 will engage the block 33 for limiting. At this time, the display board 31 is in the expanded state, which is convenient for posting warning posters.

[0042] After the device is used, the handle 42 is pulled upward to drive the slide 41 and the stop block 44 to move upward to release the limit on the block 33, and then the block 33 is moved in the opposite direction along the track of the L-shaped groove 301 to store the display board 31, thereby reducing the space occupied when the device is idle.

[0043] Finally, remove the fixing piles and other fixing parts from the fixing holes 501, and pull the pull ring 52 to drive the round rod 53, the limit block 56 and the limit groove 502 to disengage and release the limit on the support leg 51. After the limit is released, rotate the support leg 51 in the opposite direction to store the support leg 51. After storage, release the pull ring 52. Under the action of the limit spring 55, the limit block 56 and the round rod 53 will be plugged into the limit groove 502 to limit the support leg 51, completing the storage of the device for easy carrying.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
