By setting the first horizontal plate 411, the first vertical plate 412, the second horizontal plate 423, and the second vertical plate 424, and connecting the first horizontal plate 411 and the second horizontal plate 423 with screws, and connecting the first vertical plate 412 and the second vertical plate 424 with screws, the upper connector 41 can be connected to the left part 421 and the right part 422, which is convenient for assembly.

[0041] The left part 421 and the right part 422 are each provided with a third vertical plate 425 on the front side of their lower ends, and a fourth vertical plate 426 is provided on the rear side of their lower ends. The third vertical plate 425 and the fourth vertical plate 426 are both connected to the lower connector 43 by screws. By setting the third vertical plate 425 and the fourth vertical plate 426, and by connecting the third vertical plate 425 and the fourth vertical plate 426 to the lower connector 43 by screws, the left part 421 and the right part 422 are both connected to the upper connector 41, which facilitates assembly.

[0042] One of the fourth vertical plates 426 is provided with a first positioning groove 427. The opening of the first positioning groove 427 is open in the left-right direction and penetrates the front and rear surfaces of the fourth vertical plate 426. The other fourth vertical plate 426 is provided with a first positioning block 428. During assembly, the first positioning block 428 extends into the first positioning groove 427. By setting the first positioning groove 427 and the first positioning block 428, the two can cooperate to position the left part 421 and the right part 422, improving the assembly accuracy. At the same time, the opening of the first positioning groove 427 is open in the left-right direction and penetrates the front and rear surfaces of the fourth vertical plate 426, so that the first positioning block 428 can extend into the first positioning groove 427 in the left-right direction or the front-back direction, making assembly more convenient.

[0043] The lower end of the right part 422 has a second positioning groove 4221 on the right side. The opening of the second positioning groove 4221 is downward and extends through the left and right surfaces of the right part 422. The upper end of the lower connector 43 has a second positioning block corresponding to the second positioning groove 4221. During assembly, the second positioning block extends into the second positioning groove 4221. It can be understood that the lower end of the left part 421 also has a second positioning groove 4221 on the left side. By setting the second positioning groove 4221 and the second positioning block, the opening of the second positioning groove 4221 is downward and extends through the left and right surfaces of the right part 422, so that the right part 422 and the lower connector 43 have high assembly accuracy and are easy to assemble.

[0044] The inner wall of the upper end of the sleeve 31 is formed with a radially inward extending connecting plate 312. The connecting plate 312 is connected to the upper connecting member 41 by screws. For example, there are two connecting plates 312. Specifically, the connecting plate 312 is connected to the first horizontal plate 411 by screws. By forming a radially inward extending connecting plate 312 on the inner wall of the upper end of the sleeve 31, the sleeve 31 can be installed and fixed by connecting it to the upper connecting member 41 by screws. The assembly is convenient, and the connecting structure is located inside the sleeve 31, making the sleeve 31 simple and beautiful in appearance.

[0045] The inner top wall of the end cap 32 is formed with a plurality of elastic hooks 321, and the upper connector 41 is provided with a plurality of locking holes 413. The elastic hooks 321 cooperate with the corresponding locking holes 413 so that the end cap 32 is locked with the upper connector 41.

[0046] The upper connector 41 is provided with a mounting groove 414, which is located above the first horizontal plate 411. The opening of the mounting groove 414 is open upward. A constant force spring 60 is provided in the mounting groove 414. The free end 61 of the constant force spring 60 extends downward and is connected to the lifting seat 51. The constant force spring 60 is prior art, and its function is to keep the display fixed on the mounting part 53 at the current height position.

[0047] A concealing member 70 is provided between the left part 421 and the right part 422. The concealing member 70 has a left side part 71 and a right side part 72. The left side part 71 is detachably connected to the left part 421, and the right side part 72 is detachably connected to the right part 422.

Both the left side part 71 and the right side part 72 are provided with elongated holes 75 extending in the vertical direction and communicating with the receiving groove 73. The slide rail assembly 52 is located in the corresponding elongated holes 75. The receiving groove 73 has first openings 7 on both the front and rear sides extending in the vertical direction. 4. The sleeve 31 has a second opening 311 on both the front and rear sides, corresponding to the first opening 74. The mounting part 53 on the lifting seat 51 extends forward beyond the first opening 74 and the second opening 311. The lifting seat 51 and the mounting part 53 are connected by bolts. The axis of the bolts extends in the front-rear direction. When the lifting seat 51 and the mounting part 53 are assembled or disassembled, the first opening 74 and the second opening 311 on the rear side can allow the bolts to enter and exit. By setting the concealing part 70, the internal structure of the left part 421 and the right part 422 is concealed to avoid exposure, making the column 20 look simpler and more beautiful.

[0048] The right side component 72 is provided with a plurality of elastic locking blocks 76 distributed in the vertical direction, and the right part 422 is provided with a plurality of locking slots 4222. The elastic locking blocks 76 cooperate with the corresponding locking slots 4222 so that the right side component 72 is engaged with the right part 422. The installation structure of the left side component 71 is the same as that of the right side component 72, so it will not be described in detail.

[0049] It should be noted that the snap-fit ​​method and the screw connection method of this utility model can be substituted for each other. In addition, in order to facilitate the disassembly of the end cap 32, multiple annularly distributed notches (not shown) can be provided between the periphery of the end cap 32 and the sleeve 31, and an inclined surface (not shown) can be provided on the elastic hook 321. When the disassembly tool is inserted into the notch and the end cap 32 is pried upward with a little force, the end cap 32 is subjected to external force, which can cause the elastic hook 321 to disengage from the locking hole 413 under the guidance of the inclined surface, thereby facilitating the disassembly of the end cap 32.
