The side walls on both sides of the pressure plate 43 are respectively provided with first tooth portions that mesh with the two first gears 44, and the bottoms of the two clamping plates 3 are respectively provided with second tooth portions that mesh with the two first gears 44. When the identification plate pushes the U-shaped pressure plate 43 to move downward, the two first gears 44 on both sides are driven to rotate clockwise and counterclockwise respectively, thereby driving the two clamping plates 3 to move toward each other along the socket 11 to clamp and fix the identification plate.

[0023] The two clamping plates 3 are both slidably connected to the first support plate 12 having a through slot, the first support plate 12 is fixedly connected to the inner wall of the installation box 1 above the baffle plate 41, and the second latching teeth of the two clamping plates 3 respectively pass through the through slots and mesh with the two first gears 44. Two second support plates 13 are arranged opposite to each other between the first support plate 12 and the baffle plate 41, one end of the two second support plates 13 is fixedly connected to the inner wall of the installation box 1, and the other end is rotatably connected to the two first gears 44 respectively.

[0024] The bottom end of the first pressure rod 42 passes through the baffle 41 and is fixedly connected to a plurality of inverted trapezoidal limit blocks 5, and the plurality of limit blocks 5 are arranged at equal distances. A plug plate 6 is provided on one side of the first pressure rod 42, and one end of the plug plate 6 is connected to the inner wall of the installation box 1 below the baffle 41 through a second spring 7, and the other end has an inclined surface adapted to the side wall of the limit block 5, so that during the downward pressing process of the first pressure rod 42, the inclined surface of the plug plate 6 slides in contact with the side wall of the first limit block 5, so that the plug plate 6 compresses the second spring 7, and when the inclined surface of the plug plate 6 separates from the side wall of the first limit block 5, the plug plate 6 is inserted into the gap between the adjacent first and second limit blocks 5 under the elastic force of the second spring 7 to limit the upward movement of the first pressure rod 42.

[0025] A reset button 8 is provided on one side of the installation box 1 , and the reset button 8 is connected to the plug board 6 through a second linkage assembly 9 , so that when the reset button 8 is pressed toward the installation box 1 , the second linkage assembly 9 drives the plug board 6 to move toward the second spring 7 .

[0026] The second linkage assembly 9 includes a second pressure rod 91 passing through the side wall of the installation box 1 and slidably connected to the side wall of the installation box 1, and a second gear 92 installed below the plug board 6. One end of the second pressure rod 91 is fixedly connected to the reset button 8, and the other end is provided with a third latching tooth portion meshing with the second gear 92. The bottom of the plug board 6 is provided with a fourth latching tooth portion meshing with the second gear 92. The second gear 92 is rotatably installed on the third support plate 14, and the third support plate 14 is fixedly connected to the inner wall of the installation box 1 below the plug board 6 and slidably connected to the plug board 6.

[0027] The reset button 8 includes a sleeve 81 fixedly connected to the outer wall of the installation box 1, a T-shaped pressure block 82 slidably installed in the sleeve 81, and a third spring 83 connected between the pressure block 82 and the end wall of the sleeve 81. The second pressure rod 91 passes through the side wall of the installation box 1 and the end wall of the sleeve 81 in sequence and is fixedly connected to the pressure block 82.

[0028] When the present application is used, the installation box 1 is fixedly installed on the ground beside the highway through the support column 2, and the traffic sign for indicating or warning the highway is inserted into the box body 1 from the socket 11 of the installation box 1. In the process of the sign pushing the U-shaped pressure plate 43 to move downward, the two first gears 44 on both sides are respectively driven to rotate clockwise and counterclockwise, thereby driving the two clamping plates 3 to move toward each other along the socket 11 to clamp and fix the sign; the U-shaped pressure plate 43 simultaneously compresses the first spring 45 and drives the first pressure rod 42 to move downward, and the inverted trapezoidal limit block 5 at the bottom of the first pressure rod 42 is adapted to contact with the plug plate 6, and the inclined surface of the plug plate 6 is in sliding contact with the side wall of the first limit block 5, so that the plug plate 6 compresses the second spring 7, and when the inclined surface of the plug plate 6 is separated from the side wall of the first limit block 5 , the insert plate 6 is inserted into the gap between the first and second adjacent limit blocks 5 under the elastic force of the second spring 7 to limit the first pressure rod 42 from moving upward. When the identification plate is clamped and fixed, the insert plate 6 is inserted into the gap between any two adjacent limit blocks 5 to limit the first pressure rod 42 from moving upward in the opposite direction, thereby forming a stable clamped and fixed installation structure; when the identification plate is to be removed and replaced, the pressure block 82 is pressed in the direction of the installation box 1, the third spring 83 is compressed and the second pressure rod 91 is pushed to move leftward, driving the second gear 92 to rotate clockwise, thereby driving the insert plate 6 to disengage from the gap between the two adjacent limit blocks 5. At this time, the first pressure rod 42 moves upward under the resetting action of the first spring 45, loosening the two clamping plates 3, and removing the identification plate from the installation box 1, thereby completing the removal of the identification plate.
