[0056] Combination Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.11 as well as Fig.12 As shown, the roller body mounting plate 2050201 of the roller body 20502 is installed in the second open groove 2050101 of the open cylinder 20501, and the roller body mounting plate 2050201 is inserted into the clamping plate 2050103 through the clamping groove 2050205, thereby limiting the up and down displacement of the roller body 20502, and the two side surfaces of the roller body mounting plate 2050201 are abutted against the two side surfaces of the second open groove 2050101.

[0057] The open cylinder 20501 of the roller assembly 205 is installed in the cylindrical groove 20204, and the bottom surface of the open cylinder 20501 abuts against the bottom surface of the cylindrical groove 20204. The width dimension of the long strip opening 20302 of the lower support rod 203 is slightly larger than the diameter of the roller 2050204. The diameter dimension of the roller 2050204 is smaller than the axial length of the lower cylindrical rod 2050203 after the roller 2050204 is installed. The width dimension of the roller groove 20301 of the lower support rod 203 is larger than the axial length of the lower cylindrical rod 2050203 after the roller 2050204 is installed. The width dimension of the roller groove 20301 of the lower support rod 203 is larger than the width dimension of the long strip opening 20302 of the lower support rod 203.

[0058] The bottom surface of the roller body mounting plate 2050201 abuts against the bottom surface of the cylindrical groove 20204.

[0059] The roller 2050204 of the roller assembly 205 is installed in the roller groove 20301 and is rollingly connected to the roller groove 20301. The fixing nut 20503 is screwed and connected with the fixing stud 2050102 of the open cylinder 20501, and the bottom surface of the fixing nut 20503 abuts against the top surface of the upper support rod 202 to fix the open cylinder 20501.

The spring fixing bodies 20402 at the two ends of the telescopic spring assembly 204 are respectively installed in the spring assembly installation holes 20206 of the two upper support rods 202, and the screws 206 extend into the spring assembly positioning holes 20207 and are screwed and connected with the threaded holes 20403 to position the telescopic spring assembly 204. The reset tension of the telescopic spring 20401 of the telescopic spring assembly 204 can tighten the frame 101 on both sides of the packaging box, thereby increasing the strength of the packaging box. At the same time, the telescopic function of the telescopic spring 20401 makes the support rod assembly 2 applicable to packaging boxes of more sizes. Because the telescopic length of the telescopic spring 20401 is within a certain range, when the upper support rod 202 and the lower support rod 203 slide, the upper support rod 202 and the lower support rod 203 will not be disconnected.

[0061] like Fig.13As shown, when installing the roller assembly 205, first align the second opening groove 2050101 of the open cylinder 20501 with the first opening groove 20205, the second opening groove 2050101 and the first opening groove 20205 are equal in width, insert the roller body mounting plate 2050201 of the roller body 20502 into the second opening groove 2050101 of the open cylinder 20501, and then align the second opening groove 2050101 of the open cylinder 20501 with the first opening groove 20205. 1 is inserted into the card plate 2050103 through the card slot 2050205. At the same time, the roller 2050204 of the roller body 20502 enters the roller groove 20301 through the long strip opening 20302 of the lower support rod 203. The roller 2050204 abuts against the bottom surface of the roller groove 20301. The axial direction of the lower cylindrical rod 2050203 after the roller 2050204 is installed is parallel to the length direction of the roller groove 20301, and then rotated to The opening cylinder 20501 makes the second opening slot 2050101 of the opening cylinder 20501 perpendicular to the first opening slot 20205. At the same time, the opening cylinder 20501 drives the roller body 20502 to rotate 90°, so that the roller 2050204 of the roller body 20502 rotates 90°. At this time, the axial direction of the lower cylindrical rod 2050203 after the roller 2050204 is installed is perpendicular to the length direction of the roller slot 20301. At this time, the roller 2050204 is in contact with the upper top surface and the lower bottom surface of the roller groove 20301, the bottom surface of the roller body mounting plate 2050201 is in contact with the bottom surface of the cylindrical groove 20204, the fixing nut 20503 is screwed together with the fixing stud 2050102, and the fixing nut 20503 is tightened to limit the upper and lower positions of the lower support rod 203 in the upper support rod 202, so that the lower support rod 203 will not fall off in the upper support rod 202.

[0062] During operation, first clamp one end of the support rod assembly 2 on the frame 101 on one side. Because the upper support rod 202 is slidably connected to the lower support rod 203, and the telescopic function of the telescopic spring 20401 pulls the other end of the support rod assembly 2 and clamps the other end of the support rod assembly 2 on the frame 101 on the other side.

[0063] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
