[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: The chopstick-style tape roller solves the problem that existing tape rollers, which are fixed to a tabletop, occupy a large amount of space, making them inconvenient to use and affecting ease of use. By rotating and fitting the first bracket 1 and the second bracket 2 together, the area to be rolled up can be reduced, thereby improving portability. The following is disclosed:

[0032] The left side of the first bracket 1 is connected to the second bracket 2 via a hinge; the second bracket 2 has a through hole 5 inside, and a guide wheel 6 is welded to the top of the second bracket 2. The left end of the second bracket 2 is connected to a pedal 4 via a hinge, and a handle 3 is welded to the right side of the first bracket 1. The second bracket 2 and the rear end of the first bracket 1 are connected by a latch 7; the rear end of the first bracket 1 is provided with a crank handle 10, and the front end of the first bracket 1 is rotatably connected to a tape clamp 13. The top of the first bracket 1 is welded with a limit hole 8, and a tape unloader 9 is slidably connected inside the limit hole 8. The height of the through hole 5 is greater than the height between the tape clamps 13, and the tape clamps 13 and the tape unloader 9 form a fitting sliding mechanism. The first bracket 1 and the second bracket 2 are made of 10cm x 5cm x 3mm high-strength steel, and the combined length of the first bracket 1 and the second bracket 2 is 1m.

[0033] refer to Figures 1 to 3 When it is necessary to carry it, by separating the buckle 7, the first bracket 1 and the second bracket 2 can be rotated by the hinge, so that the first bracket 1 and the second bracket 2 can fit together. The cable clip 13 will pass through the inside of the through hole 5, and the pedal 4 will fit against the surface of the second bracket 2 by the hinge. This reduces the volume after the first bracket 1 and the second bracket 2 are fitted together, making it easier to place inside the vehicle and avoid taking up too much vehicle space, thus achieving the purpose of easy carrying. Furthermore, by reversing the above operation, the first bracket 1 and the second bracket 2 can be fixed by the locking between the buckles 7, which makes it easier to reel in the water pipe later.

[0034] Example 2: The chopstick-type hose reel solves the problem of the large amount of physical effort required to reel in water pipes. Through the cooperation between the first gear 11 and the second gear 12, the force required can be reduced, thus facilitating the reeling of water pipes. The following is disclosed:

[0035] The front end of the crank handle 10 is connected to a first gear 11, and the left end of the first gear 11 is engaged with a second gear 12. The first gear 11 and the second gear 12 are rotatably connected inside the first bracket 1. The diameter of the first gear 11 is smaller than that of the second gear 12. The crank handle 10 is made of aluminum alloy and has a length of 20cm. The first gear 11 and the second gear 12 form a differential structure, and the speed ratio of the first gear 11 to the second gear 12 is 15 / 30.

[0036] refer to Figures 1 to 5 The second bracket 2 is brought into contact with the ground, causing the pedal 4 to rest against the ground. The water pipe is then passed through the guide wheel 6 into the tape clamp 13. The tape unloader 9 is pulled, disengaging it from the limiting hole 8. The tape unloader 9 is then inserted back into the tape clamp 13, thus limiting the water pipe. The second bracket 2 is secured by pressing the pedal 4 with the foot. The crank handle 10 is then turned, causing the first gear 11 to rotate. This rotation of the first gear 11 then drives the second gear 12 to rotate, thus... The second gear 12 can drive the tape clamp 13 to rotate, thereby winding the water pipe through the tape clamp 13. Since the first gear 11 and the second gear 12 form a differential, the crank handle 10 can be rotated with a weak force, thereby reducing the force required to wind the water pipe and making it easier to wind the water pipe. After winding, by pulling the tape release device 9, the tape release device 9 can be disengaged from the inside of the tape clamp 13. Then, by pulling the water pipe, the water pipe can be disengaged from the tape clamp 13, thus facilitating the subsequent placement of the water pipe.

[0037] Example 3: The chopstick-type tape reel solves the problem of poor stability and easy fall-off of the tape unloader 9 in Example 2. The use of the pin 14 can limit the tape unloader 9, thereby improving installation stability. The following is disclosed:

[0038] A pin 14 is slidably connected inside the limiting hole 8, and the middle part of the pin 14 penetrates the inside of the positioning hole 15. The positioning hole 15 is opened on the tape unloader 9. The bottom of the pin 14 is made of magnetic material, and the limiting hole 8 is made of iron material.

[0039] refer to Figure 1 and Figure 6 Pulling the pin 14 allows it to slide inside the first bracket 1, thus moving the pin 14 away from the positioning hole 15. This allows the tape unloader 9 to move inside the limiting hole 8. When the pin 14 is fixed to the tape unloader 9 through the positioning hole 15, the pin 14 is connected to the limiting hole 8 through a magnet, thus preventing the pin 14 from falling off. Therefore, the stability of the tape unloader 9 inside the limiting hole 8 can be improved.

[0040] Working principle: When using this chopstick-style tape reel, first, refer to... Figures 1 to 3 When it is necessary to carry it, by separating the buckle 7, the first bracket 1 and the second bracket 2 can be rotated by the hinge, and the cable clip 13 will pass through the inside of the through hole 5, and the pedal 4 will be attached to the surface of the second bracket 2 by the hinge, so that the first bracket 1 and the second bracket 2 can be attached together to reduce the volume, thus avoiding taking up too much vehicle space. And by reversing the above operation, the first bracket 1 and the second bracket 2 can be fixed by the locking between the buckles 7, which makes it easier to roll up the water pipe later.

[0041] refer to Figures 1 to 5 The second bracket 2 is brought into contact with the ground, and the pedal 4 is then placed against the ground. The water pipe is then passed through the guide wheel 6 into the webbing clamp 13. The unloader 9 is pulled, causing it to disengage from the limiting hole 8, thus limiting the water pipe. The second bracket 2 is fixed by pressing the pedal 4 with the foot, which causes the first gear 11 to rotate, driving the second gear 12 to rotate. The second gear 12 then drives the webbing clamp 13 to rotate. Since the first gear 11 and the second gear 12 form a differential, the force required to wind up the water pipe is reduced, making it easier to wind up the water pipe. After winding, the unloader 9 is pulled, causing it to disengage from the webbing clamp 13. The water pipe is then pulled, causing it to disengage from the webbing clamp 13, making it easier to place the water pipe later.

[0042] refer to Figure 1 and Figure 6 Pulling the pin 14 allows the pin 14 to slide inside the first bracket 1, which in turn allows the tape unloader 9 to move inside the limiting hole 8. When the pin 14 is fixed to the tape unloader 9 through the positioning hole 15, the pin 14 will be connected to the limiting hole 8 through a magnet, thus improving the stability of the tape unloader 9 inside the limiting hole 8.
