DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] Example 1:

[0035] The present application discloses an adjustable bag opener. Figure 1 The adjustable bag opener includes a base 1, a support rod 2 and a positioning rod 3. The support rod 2 is arranged on the base 1, and the base 1 mainly plays a supporting role; the support rod 2 is arranged on the base 1, and at least three support rods 2 are arranged at intervals along the edge of the base 1; the positioning rod 3 is an arc-shaped rod, which is arranged at the upper end of the support rod 2, and the upper ends of all support rods 2 are connected to the positioning rod 3. A storage space 4 for accommodating bags is formed between the base 1, the support rod 2 and the positioning rod 3; one end of the positioning rod 3 is open to form an outlet for the bag to enter and exit. When in use, the upper end opening of the bag can be flipped outward and put on the positioning rod 3, and the bag can be opened for loading; after the bagging is completed, the bag can be removed from the opening into the storage space 4. This structural design allows the bag to be conveniently filled with items in the opened state, thereby improving the filling efficiency and reducing labor costs.

[0036] Reference Figure 1 and Figure 2 In the embodiments of the application, the base 1 is arranged horizontally and can be a single metal plate or a plurality of welded metal rods. This ensures sufficient rigidity and stability while reducing the weight of the spreader. The lower surface of the base plate is provided with a pulley 5 for sliding the base 1. Multiple pulleys 5 are provided, preferably no fewer than four, to ensure stability during movement. Furthermore, a brake is preferably provided on the pulley 5 to stabilize the spreader during use.

[0037] Reference Figure 1 and Figure 2In the embodiment of the present application, a first mounting rod 11 is welded to the upper surface of the base 1, a second mounting rod 31 is welded to the lower surface of the positioning rod 3, and the support rod 2 is detachably connected between the first mounting rod 11 and the second mounting rod 31. Specifically, the first mounting rod 11 and the second mounting rod 31 are each provided with a mounting groove on one end facing the support rod 2, and the upper and lower ends of the support rod 2 are respectively inserted into the two mounting grooves with interference fit. The upper and lower ends of the support rod 2 are both provided with chamfers to facilitate insertion into the mounting grooves. This structural design allows the support rod 2 to be firmly fixed between the base 1 and the positioning rod 3, ensuring the stability of the entire device. The chamfered design facilitates the insertion and removal of the support rod 2, making it easy to maintain and replace.

[0038] Reference Figure 1 and Figure 2 In the embodiment of the present application, the support rod 2 optionally includes a first rod 21, a second rod 22, and a first positioning member 23. The lower end of the first rod 21 is connected to the first mounting rod 11, the lower end of the second rod 22 is inserted into the first rod 21 for vertical sliding, and the upper end of the second rod 22 is connected to the second mounting rod 31. The first positioning member 23 can limit the vertical sliding of the second rod 22 within the first rod 21. This design allows the support rod 2 to be flexibly adjusted in length, and thus the height position of the top positioning rod 3 to accommodate bags of different sizes.

[0039] For reference, the support rod 2 can be adjusted to a range of 30 cm, and the positioning rod 3 can be set to a maximum height of 90 cm and a minimum height of 60 cm, thereby adapting to the size of bags commonly used in daily life. In other special occasions, the length of the support rod 2 and its telescopic adjustment range can also be adjusted according to actual conditions.

[0040] Reference Figure 1 and Figure 2 In this embodiment, a threaded seat 211 is welded to the outer wall of the first rod 21 and is welded to the upper end of the first rod 21. A threaded hole is formed in the threaded seat 211, which connects to the interior space of the first rod 21. The first positioning member 23 is a positioning bolt, the rod of which is threaded into the threaded hole, and the end of the positioning bolt can abut the outer wall of the second rod 22. The head of the positioning bolt is preferably butterfly-shaped to apply force to it. This structural design ensures that when the second rod 22 slides up and down to the appropriate position, the positioning bolt can abut the outer wall of the second rod 22, thereby securing the second rod 22 and preventing it from loosening during use.

[0041] Reference Figure 1 and Figure 2In this embodiment, the positioning rod 3 is an arcuate steel tube with a vertical portion at each end of the opening. During use, the upper edge of the bag is first flipped over and placed over the arcuate portion of the positioning rod 3 for positioning. The entire bag is then placed over the positioning rod 3 along the extending direction of the two ends of the positioning rod 3. To improve the adaptability of the expander, the positioning rod 3 is slidably connected to the two ends of the opening. Two second positioning members 7 are provided on the positioning rod 3, corresponding to the two adjusting rods 6. The second positioning members 7 can be the same as the first positioning member 23, and are also provided with bolts to tighten the positioning and adjusting rods 6.

[0042] Reference Figure 1 and Figure 2 In the embodiment of the present application, a fixing post 8 is welded and fixed to the upper surface of the positioning rod 3. At least three fixing posts 8 are provided at intervals along the extension direction of the positioning rod 3. The function of the fixing posts 8 is to fix the bag during the filling process to prevent the bag from slipping.

[0043] The implementation principle of the adjustable bag opener in the embodiment of the present application is as follows: when in use, first slide the second rod 22 according to the needs of use, adjust the height of the positioning rod 3, and slide the adjustment rod 6 to adjust the size of the space enclosed by the positioning rod 3; then place the lower end of the bag in the accommodating space 4, and allow the lower surface of the bag to abut against the base 1; then flip the opening of the upper end of the bag over and put it on the positioning rod 3, and at the same time, the upper edge of the bag can be fixed by the positioning rod 3, thereby completing the bag opening process.

[0044] Example 2:

[0045] The difference between the embodiment of the present application and embodiment 1 is that a fixing clip 9 is used instead of the positioning rod 3 to position the bag. Figure 3 Specifically, the fixing clamp 9 is disposed on the upper surface of the positioning rod 3, with at least three fixing clamps 9 spaced apart along the extending direction of the positioning rod 3. The fixing clamp 9 includes a first block 91, a second block 92, a first fixing member 93, and a second fixing member 94. The first block 91 is hingedly connected to the positioning rod 3. When the first block 91 is rotated away from the receiving space 4, the first fixing member 93 can secure the first block 91 to the positioning rod 3. The second block 92 is hingedly connected to the first block 91. When the first block 91 is rotated toward the receiving space 4, the second fixing member 94 can secure the second block 92 to the side wall of the first block 91. During use, the upper side wall of the bag is placed against the side wall of the first block 91, and the second block 92 is tilted toward the receiving space 4. The bag is clamped between the first and second blocks 91, 92 by the second fixing member 94. The bag is then tilted away from the receiving space 4 and secured to the positioning rod 3 by the first fixing member 93. This effectively secures the edge of the bag and improves the stability of the loading process.

[0046] Reference Figure 3 and Figure 4 Specifically, the first fixing member 93 is a fixing protrusion, and the side wall of the positioning rod 3 is provided with a fixing groove for the fixing protrusion to be interference-engaged. This structural design allows the fixing protrusion to be firmly fixed to the positioning rod 3, preventing it from loosening during use. The second fixing member 94 is a fixing magnetic piece provided on the side wall of the second block 92. When the second block 92 rotates toward the first block 91, the fixing magnetic piece can be magnetically attracted to the side wall of the first block 91. This design allows the second block 92 to be firmly fixed to the first block 91, preventing it from loosening during use. At the same time, through magnetic attraction, operation is convenient and quick, and will not cause damage to the bag.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
