[0024] Specifically, a first telescopic cavity 102 is formed in the fixed column 1 and located on the left and right sides of the plug slot 101, the cavity is used for accommodating a limiting plate 301 and the positioning rod 302 of the fixed assembly 3, and space is provided for sliding of the positioning rod 302 and telescoping of a first telescopic spring 304. A second telescopic cavity 103 is formed at the bottom end of the plug slot 101 and is used for accommodating the pop-up assembly, the pop-up assembly comprises a second telescopic spring 201 and a limiting seat 202, so that the plug rod 4 can be pushed out upward through the pop-up assembly after the positioning rod 302 releases the fixed plug rod 4, and the signboard can be quickly replaced by the staff.

[0025] The fixed assembly 3 includes a limiting plate 301 slidingly connected in the first telescopic cavity 102, which supports and guides the sliding of the positioning rod 302, and transmits the elastic force of the first telescopic spring 304. The center of the limiting plate 301 is fixedly installed with the positioning rod 302, one end of which penetrates the inner wall of the first telescopic cavity 102 and extends to the outside of the fixed column 1, and the outer end is fixedly connected with a pull ring 303. The pull ring 303 is used to facilitate the manual pulling of the positioning rod 302 by the staff, so as to pull out the positioning rod 302 from the positioning hole 401 of the plug rod 4, and release the limiting and fixing of the plug rod 4. The other end of the positioning rod 302 penetrates the inner wall of the first telescopic cavity 102 and extends into the plug slot 101, and is used to be inserted into the positioning hole 401 of the plug rod 4, and the limiting and fixing of the plug rod 4 is achieved by clamping. The middle part of the positioning rod 302 is sleeved with the first telescopic spring 304, one end of which is fixedly connected to the inner wall of the first telescopic cavity 102, and the other end is fixedly connected with the limiting plate 301, which provides a rebound force to make the positioning rod 302 automatically reset after the operation is completed.

[0026] The inside of the plug rod 4 is provided with a positioning hole 401 matched with the positioning rod 302, and the two positioning rods 302 located at the left and right sides of the positioning hole 401 in the plug slot 101 are inserted into the positioning hole 401 respectively, so as to realize stable limiting and fixing. The upper part of the plug rod 4 is cylindrical, and the bottom part is conical. The function of this design is that when the plug rod 4 is inserted into the plug slot 101, the gradually expanding part of the conical bottom part can push the positioning rod 302 to slide into the first telescopic cavity 102, and compress the first telescopic spring 304, so as to provide space for the insertion of the plug rod 4. When the plug rod 4 continues to extend into the positioning hole 401 and aligns with the positioning rod 302, the rebound force of the first telescopic spring 304 pushes the positioning rod 302 to insert into the positioning hole 401, so as to realize the limiting and fixing of the plug rod 4.

[0027] The elastic lifting assembly 2 includes a second telescopic spring 201 fixedly connected to the bottom wall of the second telescopic cavity 103. The spring provides an upward elastic force, which pushes the plug rod 4 to move upward by a distance after the positioning rod 302 releases the limiting and fixing of the plug rod 4, so as to facilitate the staff to take out the signboard. The top end of the second telescopic spring 201 is fixedly connected with a limiting seat 202. The limiting seat 202 serves as a supporting member for the bottom end of the plug rod 4, bears the plug rod 4 and transmits the elastic force of the second telescopic spring 201 to the plug rod 4, so as to realize the stable elastic lifting of the plug rod 4. The top end of the limiting seat 202 is provided with a limiting groove 202a for accommodating and positioning the bottom end of the plug rod 4, so as to ensure that the plug rod 4 remains stable and does not deviate during the up and down movement in the plug slot 101. The bottom end of the plug rod 4 is inserted into the limiting groove 202a, and the conical design at the bottom part is tightly matched with the limiting groove 202a, so as to provide stable support and guidance when the plug rod 4 is inserted or elastically lifted.

[0028] The working principle of the device is: when the sign needs to be replaced, the staff only needs to pull the pull ring 303 on both sides of the fixed column 1 at the same time, and then the clamping end of the two positioning rods 302 can be pulled out of the positioning hole 401, at this time, under the action of the rebounding force of the second extension spring 201, the insertion rod 4 can be pushed out a distance upward through the limiting seat 202, at this time, the insertion rod 4 can be separated from the positioning rod 302 in the insertion slot 101, and the limiting and fixing of the insertion rod 4 are released, so that the sign 5 can be removed and a new sign can be replaced; when the new sign 5 is installed, only the bottom end of the insertion rod 4 needs to be quickly inserted into the insertion slot 101, when the insertion rod 4 enters the insertion slot 101, the sharp end at the bottom of the insertion rod 4 can pass through the gap between the two positioning rods 302, and as the insertion rod 4 continues to penetrate, the cross section at the bottom gradually expands, which will force the clamping end of the two positioning rods 302 to move into the first extension cavity 102, the limiting plate 301 on the positioning rod 302 can press the first extension spring 304, so that the first extension spring 304 is compressed, and as the insertion rod 4 continues to penetrate, the bottom end of the insertion rod 4 can be inserted into the limiting groove 202a of the limiting seat 202 and drive the limiting seat 202 to move downward, the limiting seat 202 can force the second extension spring 201 to compress, when the bottom surface of the limiting seat 202 abuts against the inner bottom wall of the insertion slot 101, the positioning hole 401 opened in the insertion rod 4 can be on the same horizontal line with the two positioning rods 302, at this time, without the blockage of the side wall of the insertion rod 4, under the action of the rebounding force of the first extension spring 304, the two positioning rods 302 can be bounced back to the initial position, that is, the clamping end of the two positioning rods 302 can be inserted into the positioning hole 401, so that the insertion rod 4 is limited and fixed in the insertion slot 101, thereby completing the replacement work of the sign 5.
