[0042] like Figure 1-8 As shown, the portable wire feeder includes a vertical rod 1, which has an internal hollow structure to further reduce weight. The vertical rod 1 is preferably made of aluminum alloy, which is relatively lightweight, strong and corrosion resistant. The vertical rod 1 is provided with a wire feed structure and a support structure, with the support structure located below the wire feed structure.

[0043] The wire feeding structure includes multiple wire feeding components 2 with the same structure, and the multiple wire feeding components 2 are evenly distributed along the circumferential direction of the vertical rod 1;

[0044] Each wire feeding assembly 2 includes a support rod 201. One end of the support rod 201 is rotatably mounted on the vertical rod 1. The purpose of the rotatable mounting is to facilitate the folding and storage of the support rod 201. Generally, a U-shaped seat is used. The U-shaped seat is mounted on the vertical rod 1. One end of the support rod 201 is fixed to the two side walls of the U-shaped seat through a pivot, and the end of the support rod 201 is rounded to ensure that the support rod 201 can rotate freely around the pivot without causing interference.

[0045] The support rod 201 is provided with a first rope 208, which is generally made of metal chain. Metal chain is not easy to stretch and has a strong load-bearing capacity. The outside of the first rope 208 can also be covered with a protective layer made of rubber. The protective layer can effectively prevent the cable sheath from being worn during the cable laying process, and further ensure that the support rod 201 is horizontal and not pressed down by the cable roll. One end of the first rope 208 is set in the upper middle part of the vertical rod 1, and the other end of the first rope 208 is set on the side of the support rod 201 that is biased towards the vertical rod 1. When the first rope 208 is in a taut state, the support rod 201 is in a horizontal state. That is, the support rod 201 is kept in a horizontal state by the tension of the first rope 208 to support the cable roll.

[0046] The support structure includes multiple support legs 3 evenly distributed along the circumferential direction of the vertical rod 1. The upper end of each support leg 3 is rotatably mounted on the vertical rod 1. The purpose of the rotatable mounting is to facilitate the folding and storage of the support leg 3. Generally, a U-shaped base is used. The U-shaped base is mounted on the vertical rod 1. One end of the support leg 3 is fixed to the two side walls of the U-shaped base through a pivot, and the end of the support leg 3 is rounded to ensure that the support leg 3 can rotate freely around the pivot without causing interference.

[0047] A second rope 4 is installed between the lower end of each support leg 3 and the lower end of the vertical rod 1. The second rope 4 is generally made of metal chain, which is not easily stretched and has a strong load-bearing capacity. When the second rope 4 is taut, the corresponding support leg 3 is fully open. At this time, the second rope 4 is in a horizontal state and the lower end of the vertical rod 1 is higher than the lower end of the support leg 3. That is, only the lower ends of multiple support legs 3 are in contact with the ground, and the lower end of the vertical rod 1 is always suspended in the air and will not contact the ground.

[0048] like Figure 1-5 As shown, in this embodiment, in order to easily adapt to cable reels of different diameters, the support rod 201 includes a first round rod 2011 and a second round rod 2012, both of which have the same diameter.

[0049] One end of the first round rod 2011 is rotatably mounted on the vertical rod 1, and one end of the first rope 208 is located on one side of the middle of the first round rod 2011, biased towards the vertical rod 1;

[0050] A rectangular groove 202 is provided at the end of the first round rod 2011 away from the vertical rod 1. A connecting slide rod 203 adapted to the rectangular groove 202 is provided at the end of the second round rod 2012 near the first round rod 2011. The second round rod 2012 can only move horizontally and will not rotate, ensuring that the circular clamping rod 206 is in a vertically upward state. The length of the connecting slide rod 203 is less than the depth of the rectangular groove 202. The purpose of using the rectangular groove 202 and the connecting slide rod 203 is to ensure that the second round rod 2012 can only move horizontally and will not rotate. By using the connecting slide rod 203 in conjunction with the rectangular groove 202, the relative length between the first round rod 2011 and the second round rod 2012 can be adjusted, thereby adapting to cable rolls of different diameters.

[0051] A tension spring 204 is provided at the bottom of the rectangular slide groove 202. One end of the tension spring 204 is fixedly provided at the bottom of the rectangular slide groove 202, and the other end of the tension spring 204 is fixedly provided on the connecting slide rod 203. In the initial state, the connecting slide rod 203 is located inside the rectangular slide groove 202 and the tension spring 204 is in a naturally extended state. The first round rod 2011 and the second round rod 2012 are in contact.

[0052] A rectangular groove 205 is provided at the end of the second round rod 2012 away from the first round rod 2011, and one side wall of the rectangular groove 205 coincides with the end face of the second round rod 2012 away from the first round rod 2011.

[0053] A circular clamping rod 206 is rotatably disposed inside the rectangular groove 205. A connecting block 207 is provided at the lower end of the circular clamping rod 206. The lower end of the connecting block 207 is rounded and slides in contact with the bottom of the rectangular groove 205.

[0054] Both sides of the connecting block 207 are mounted on the side walls of the rectangular groove 205 via adjustable damping hinges 5. The adjustable damping hinges 5 can adjust the damping to ensure that the circular clamping rod 206 will not be squeezed down by the cable when it is vertical. The rotating design allows the circular clamping rod 206 to be folded for storage. In use, the circular clamping rod 206 is rotated to a vertical position, and then the second circular rod 2012 is pulled to pull the connecting slide rod 203 outward to ensure that the cable roll is located within the multiple circular clamping rods 206. At this time, the tension spring 204 is in a stretched state. Under the action of the tension spring 204, the circular clamping rod 206 is pressed against the cable. As the cable is unwound, the tension spring 204 will also shorten, so that the circular clamping rod 206 continues to press against the cable, preventing the cable from becoming loose and tangled, and further improving the unwound efficiency.

[0055] like Figure 6 , Figure 7 As shown in this embodiment, in order to enable the cable to rotate and be released easily during the release process, a first roller 6 is sleeved on the first round rod 2011 and the two can rotate freely relative to each other. One end of the first roller 6 is flush with the end of the first round rod 2011 that is close to the second round rod 2012. There is a gap between the other end of the first roller 6 and the corresponding first rope 208, that is, the first roller 6 will not contact the first rope 208 when it rotates to avoid interference.

[0056] The second round rod 2012 is fitted with a second roller 7 and the two can rotate freely relative to each other. The length of the second roller 7 is less than the length of the second round rod 2012. Generally, the length of the second roller 7 is slightly less than the length of the second round rod 2012. There is a gap between the second roller 7 and the first roller 6.

[0057] The circular clamp 206 is fitted with a third roller 8, and the two can rotate freely relative to each other. The length of the third roller 8 is slightly smaller than the length of the circular clamp 206. Through the arrangement of the first roller 6, the second roller 7, and the third roller 8, the cable roll rotates together with the cable roll when it is unloaded, which further reduces the resistance between the cable roll and the support rod 201 when the cable roll is unloaded, making the cable roll easy to pull and facilitate unloading.

[0058] like Figure 1 , Figure 6 , Figure 8 As shown in this embodiment, in order to facilitate the folding and storage of multiple support rods 201 and multiple support legs 3 and prevent them from falling apart, two elastic restraint straps 9 are provided on the upper end of the vertical rod 1. The multiple support rods 201 and multiple support legs 3 are tightly bound around the vertical rod 1 by the elastic restraint straps 9, so that they are fixed and will not fall apart at will, making them convenient to carry.

[0059] In this embodiment, it is preferred that the number of the plurality of cable laying components 2 is six. Too many will affect the weight, and too few will affect the cable laying efficiency. Six is ​​optimal.

[0060] In this embodiment, preferably, the number of the plurality of support legs 3 is three, which can both provide support and reduce their own weight.

[0061] In this embodiment, to avoid wear on the cable sheath during the cable laying process, the outer sides of the first roller 6, the second roller 7, and the third roller 8 are covered with a protective layer made of rubber. The protective layer can effectively prevent wear on the cable sheath during the cable laying process.

[0062] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
