Easy-to-assemble posters include arc-base easy-to-assemble posters, rectangular-base easy-to-assemble posters, and water-drop-base easy-to-assemble posters according to the different shapes of their bases. Each of the above types of easy-to-assemble posters mainly consists of a base, picture shafts 54, 62, 69, support rods 51, 59, 67, and feet 52, 60. The base is divided into an arc base, a rectangular base, and a water-drop base according to the cross-section and end-cover shapes, and mainly consists of a base shell, left end covers 48, 56, 65, and right end covers 53, 61, 68; the base shell is composed of an upper shell 50, 58, 66 and a lower shell 49, 57, 64. Assembly grooves 72, 81 are respectively made on the inner surfaces of the left end cover and the right end cover, and left-side picture-shaft seats 74 and right-side picture-shaft seats 80 are respectively made. Screw holes 71, 76, 83 are made on the outer circumferences; small feet 78, 85 are also made on the upper bottoms of the left end cover and the right end cover of the arc base, and picture-port grooves 73, 82 corresponding to the picture port are also made; chamfers are made on the left end cover and the right end cover of the rectangular base corresponding to the picture port; anti-rotation pin studs 55, 63, 70 are jointly arranged on the picture shaft and the right end cover. In the past, the assembly of the bases of various types of easy-to-assemble posters has been completely manually assembled for decades. This method is not only slow and inefficient, but more importantly, due to the relatively small manual assembly force, the left end cover and the right end cover are basically not assembled in place, ultimately resulting in insufficient connection of the base, easy loosening, deformation, and torsion, and poor structural stability, often bringing unnecessary troubles to users. In addition, in the past, due to the lack of a special tool for assembling the base, it was very inconvenient to fix the left end cover and the right end cover to the shell with screws. Usually, three people cooperated to place them randomly for operation, and the speed was even slower. How to improve the assembly method to improve the assembly speed and efficiency and improve the product quality has become the main topic for many easy-to-assemble poster manufacturers to think about.

[0003] After years of in-depth research and repeated tests, our company has independently developed a multifunctional assembling tool for the base of an easy-to-assemble poster. Using this tool to assemble the base of an easy-to-assemble poster, firstly, when assembling the left and right end covers, the machine replaces manual work, the force is controllable, the end covers are assembled tightly and in place, which can effectively improve the structural stability of the base; secondly, it provides an operation platform for screwing the screws, the operation is convenient and fast, and the speed is fast and the efficiency is high; thirdly, it is designed with multiple models, suitable for assembling multiple models of easy-to-assemble posters; generally, the assembly efficiency of the base of an easy-to-assemble poster is increased by more than six times, and it completely overcomes the deficiencies such as easy loosening, deformation, torsion, and poor stability existing in the previous assembly, and the product is deeply welcomed and praised by users.
