DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the device includes a mounting plate 1 and a mounting hole 2. The mounting hole 2 is integrally arranged inside the mounting plate 1. The mounting hole 2 is a through hole design. A displacement component 3 is arranged inside the mounting hole 2. The displacement component 3 includes a slide 301 slidably connected to the inside of the mounting hole 2. A slide rod 302 slides through the top of the slide 301. A bracket 303 is fixedly arranged at the bottom of the slide rod 302. The bracket 303 is slidably connected to the slide 301. A rotating rod 304 transferred inside the bracket 303 passes through the slide 301. A spring 305 is sleeved on the upper end of the outer side of the slide rod 302. The bottom of the spring 305 is fixedly connected to the slide 301, and the top of the spring 305 is fixedly connected to the slide rod 302. A roller sleeve 306 is fixedly sleeved on the outer side of the rotating rod 304.

[0026] The staff first pulls the slide bar 302, so that the slide bar 302 drives the bracket 303 together with the rotating rod 304 and the rolling sleeve 306 to move in the opposite direction of the mounting plate 1, and the spring 305 is deformed. The staff then puts the packaging bag on the mounting plate 1 and releases the slide bar 302. The rebound force of the spring 305 resets the rolling sleeve 306. At this time, the reset rolling sleeve 306 exerts a clamping force on the packaging bag. The staff then pulls the slide 301, so that the slide 301 drives the rolling sleeve 306 to move in the direction of the mounting hole 2, thereby making the rolling sleeve 306 and the packaging bag in a state of rolling friction. At this time, the rolling sleeve 306 smoothes the packaging bag. In this way, the packaging bag can be prevented from wrinkling after being clamped. Example 2

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the front and rear ends of the slide 301 are integrally provided with clearance holes 4, which are through-holes, and are sleeved on the outside of the rotating rod 304. The lower side of the front end of the mounting plate 1 is provided with a plurality of jacks 5 in a horizontal array, and the jacks 5 are blind holes. The front end of the rotating rod 304 is integrally provided with a limiting hole 6, which is a blind hole, and the cross section of the limiting hole 6 is square. The front end of the rotating rod 304 is sleeved with a slide plate 7, which is connected to the mounting plate 1 by sliding connection, and the top of the slide plate 7 is fixedly connected to the slide 301. The upper and lower sides of the front end of the slide plate 7 are fixed with a placement Plate 8, the two placement plates 8 are in a parallel design state, and a connecting plate 9 is slidably connected between the two placement plates 8. A limit pin 10 is fixedly provided on the upper side of the rear end of the connecting plate 9, and the cross-section of the limit pin 10 is square design, and the limit pin 10 and the limit hole 6 are in a design of overlapping with each other, and a plug pin 11 is fixedly provided on the lower side of the rear end of the connecting plate 9, and the plug pin 11 and the plug hole 5 can be plugged in for disassembly and assembly. A swivel pin 12 is connected to the lower side of the front end of the slide plate 7, and the swivel pin 12 is threadedly inserted into the connecting plate 9, and an avoidance hole 13 is integrally provided at the lower end of the interior of the slide plate 7, and the avoidance hole 13 is a through hole design.

[0028] According to the operation method in Example 1, when the slide bar 302, together with the bracket 303, the rotating rod 304 and the rolling sleeve 306, moves along the longitudinal direction of the slide 301, the displacement hole 4 makes way for the displacement space of the rotating rod 304. When the packaging bag is flattened, the staff rotates the rotating pin 12. Through the threaded transmission of the rotating pin 12 and the connecting plate 9, the connecting plate 9 drives the limiting pin 10 to be inserted into the limiting hole 6. Because the cross-sections of the limiting pin 10 and the limiting hole 6 are both square in design, the limiting pin 10 limits the rotation of the rotating rod 304. At this time, The rotating rod 304 controls the roller sleeve 306 to be in a locked state, preventing the roller sleeve 306 from rotating, ensuring the strength of the roller sleeve 306 in clamping the packaging bag, that is, ensuring the effect of the packaging bag being fixed. At the same time, the connecting plate 9 in displacement drives the latch 11 to be inserted into the current corresponding socket 5, thereby locking the state of the slide 301 after displacement. In this way, the limit pin 10 and the socket 11 are inserted into the corresponding limit hole 6 and the socket 5 in a synchronous moving manner, which improves the convenience of the staff in operating the device. The avoidance hole 13 makes room for the latch 11 to be inserted into the socket 5.
