A connecting frame 4013 is fixedly installed on the top of the connecting ring 4014, and a connecting rope 405 is fixedly installed at the bottom of the fixed rod 407. A connecting block 404 is slidably installed on the connecting rope 405, and the connecting rope 405 passes through the connecting block 404 and extends to the outside. A sliding block 408 is fixedly installed on the side of the connecting rope 405 away from the fixed rod 407, and the connecting block 404 is fixedly installed on the bottom of the inner wall of the connecting frame 401.

[0030] Reference Figure 1 - Figure 5 A second through hole 4018 is provided at the bottom of the second installation frame 4016, and a first through hole 409 is provided at the bottom of the first installation frame 4017. The vertical midline of the second through hole 4018 coincides with the vertical midline of the first through hole 409. A plug-in nail 4010 is slidably installed in the second through hole 4018, and a plug-in nail 4010 is slidably installed in the first through hole 409. The plug-in nail 4010 passes through the connecting ring 4014 and extends upward. A snap-in bead 4015 is clamped in the storage groove 4011. The first through hole 409 and the second through hole 4018 are provided to facilitate the plug-in nail 4010 to enter the space where the snap-in bead 4015 is located.

[0031] Reference Figure 1 - Figure 5 The two receiving grooves 4011 are respectively connected with the first through holes 409, the mounting plate 403 is in a "concave" shape, the sliding block 408 is in a "T" shape, and the sliding block 408 is slidably installed inside the recessed groove in the mounting plate 403, so that the sliding block 408 can only slide vertically, and the space between the mounting plate 403 and the connecting frame 401 can store the connecting rope 405 to avoid the scattered lines.

[0032] Reference Figure 1 - Figure 5A plurality of connecting frames 401 are evenly distributed on the inner wall of one side of the paper bag body 1, and a plurality of fixing rods 407 are evenly distributed on the inner wall of the paper bag body 1 and the inner wall of the side on which the connecting frame 401 is installed. There is always a fixing rod 407 corresponding to one connecting frame 401, and the connecting frame 401 and the fixing rod 407 divide the side wall of the paper bag body 1 into small areas, thereby enhancing the force-bearing strength of the device.

[0033] Reference Figure 1 and Figure 7 The protection component 3 includes a first clamping frame 301 and a second clamping frame 305. A connecting shaft 302 is fixedly installed on the outer wall of the first clamping frame 301. A torsion spring 303 is sleeved in the connecting shaft 302. One end of the torsion spring 303 is fixedly installed on the connecting shaft 302, and the other end of the torsion spring 303 is fixedly installed on the second clamping frame 305.

[0034] Reference Figure 1 and Figure 7 The torsion spring 303 is in a "concave" shape, and the second clamping frame 305 is in a "concave" shape. A plurality of first clamping blocks 304 are evenly distributed on the bottom of the inner wall of the torsion spring 303, and a plurality of second clamping blocks 306 are evenly distributed on the bottom of the inner wall of the second clamping frame 305. The plurality of second clamping frames 305 and the plurality of first clamping blocks 304 are staggered with each other, and the pulling rope 2 is clamped between the plurality of second clamping frames 305 and the first clamping blocks 304. The plurality of second clamping frames 305 and the first clamping blocks 304 are staggered with each other to increase the contact area with the pulling rope 2 and improve the stability of the clamping.

[0035] Working principle: When the device is in use, the sliding block 408 is pulled to drive the plug-in pin 4010 to move upward, passing through the first through hole 409 and the second through hole 4018 in sequence. As the plug-in pin 4010 is inserted, the card beads 4015 are squeezed toward both sides. When the card beads 4015 are squeezed, they move toward the outside of the second installation frame 4016. When the card beads 4015 and the storage groove 4011 are in the same horizontal line, the card beads 4015 are squeezed by the spring 4013 and the connecting ring 4014 on the second installation frame 4016. The card beads 4015 are snapped into the storage groove 4011, realizing the plug-in pin 4010 and the connecting rope 405. As the sliding block 408 moves upward, the sliding block 408 will drive the connecting rope 405 to pull upward, thereby shortening the distance between the connecting frame 401 and the fixing rod 407, and achieving the benefit of folding the paper bag body 1. Because the plug-in nail 4010 is fixed, the paper bag body 1 will not be reset due to the kraft paper material after being folded, resulting in folding failure. When it is needed, the connecting frame 4013 is pulled upward to drive the connecting ring 4014 to move upward, so that the snap-in bead 4015 moves toward the direction of the first installation frame 4017, so that the sliding block 408 can slide downward, and then the paper bag body 1 is opened;

[0036] When the device is used by different people, in order to avoid cross infection and bacterial growth, the second clamping frame 305 is moved and flipped, which will drive the synchronous movement of the second clamping block 306 to release the clamping quick protection component 3 of the pulling rope 2, thereby solving the problem that the traditional device directly uses the pulling rope 2 for pulling, which is easy to cause bacterial growth and cross infection after being used by multiple people.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
