The hook is attached to the inner wall of the receiving groove in the initial state. A through groove is formed at the top edge position of the hook. A rotating shaft is installed on the inner wall of the through groove. A limiting rod is sleeved on the outer wall of the rotating shaft. A rotating shaft is fixedly connected between the limiting rod and the inner wall of the through groove.
[0008] Further, the limiting rod is perpendicularly arranged with the edge position of the hook in the initial state.
[0009] Further, the rotating shaft and the torsion spring are coaxially arranged, and the torsion spring surrounds the outer wall of the rotating shaft.
[0010] Further, the through groove is adapted to the limiting rod.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1
[0024] Refer to Figure 1-5 , a multifunctional portable weighing instrument, including a spring scale body 1, a display panel 2 and a bearing rod 15. A receiving groove 4 is formed on the outer wall of the spring scale body 1. A hook 3 is hinged at the bottom of the bearing rod 15. The hook 3 is attached to the inner wall of the receiving groove 4 in the initial state. A through groove 6 is formed at the top edge position of the hook 3. A rotating shaft 7 is installed on the inner wall of the through groove 6. A limiting rod 8 is sleeved on the outer wall of the rotating shaft 7. A rotating shaft 7 is fixedly connected between the limiting rod 8 and the inner wall of the through groove 6.
[0025] It should be noted that the overall shape of the receiving groove 4 formed at the edge position of the outer wall of the spring scale body 1 is circular, while the overall shape of the hook 3 that can be accommodated therein is semicircular. It should also be noted that the specific shapes of the hook 3 and the receiving groove 4 are not determined. The user can adjust the specific shapes of the hook 3 and the receiving groove 4 according to the shape of the spring scale body 1 so that the hook 3 can be more adapted to the spring scale body 1 itself.
[0026] Furthermore, the limiting rod 8 is vertically arranged with the edge position of the hook 3 in the initial state. The through groove 6 is adapted to the limiting rod 8. Under the action of the torsion spring 9, the limiting rod 8 is vertically arranged with the edge position of the hook 3 in the initial state, so that after the item to be weighed is hung on the hook 3, the vertically arranged limiting rod 8 can limit the edge position of the hook 3 to prevent the item to be weighed from slipping from the edge position of the hook 3, ensuring the safety of the weighed item.
[0027] The adaptation of the through groove 6 and the limiting rod 8 enables the limiting rod 8 to be folded into the interior of the through groove 6 when not in use, preventing the limiting rod 8 and related connected components from being damaged by external forces.
[0028] Furthermore, the rotating shaft 7 and the torsion spring 9 are coaxially arranged. The torsion spring 9 is wound around the outer wall of the rotating shaft 7. By setting the rotating shaft 7 and the torsion spring 9 to be coaxially arranged and arranging the torsion spring 9 to be wound around the outer wall of the rotating shaft 7, the torsion spring 9 is limited by the rotating shaft 7 and will not easily deviate from its position after the limiting rod 8 rotates.
[0029] It should be noted that a first mounting block 10 and a second mounting block 11 are fixedly installed on the outer wall of the spring scale body 1. A limiting hole is provided on the side wall of the first mounting block 10, and a plug pin 12 is slidably installed on the side wall of the second mounting block 11. The plug pin 12 is adapted to the limiting hole.
[0030] By providing the first mounting block 10 and the second mounting block 11, and installing a slidable plug pin 12 on the side wall of the second mounting block 11, and providing a limiting hole adapted to the plug pin 12 on the side wall of the first mounting block 10, after the plug pin 12 is inserted into the limiting hole, it will form a barrier to the hook 3, so that the hook 3 will not easily break away from the receiving groove 4.
[0031] The top end of the plug pin 12 is fixedly connected with a circular limiting piece 13. A return spring 14 is fixedly connected between the inner wall of the limiting piece 13 and the outer wall of the second mounting block 11. By providing the limiting piece 13 and fixedly connecting the return spring 14 between the inner wall of the limiting piece 13 and the outer wall of the second mounting block 11, the limiting piece 13 and the plug pin 12 will not easily open under non-human force, and after opening, the elastic force of the return spring 14 will drive the limiting piece 13 and the plug pin 12 to reset, so that the plug pin 12 can continuously limit the hook 3.
[0032] In addition, a rotatable hanging ring 5 is installed at the top end of the outer wall of the spring scale body 1. By providing the hanging ring 5, the whole device can be hung somewhere for use or carried by hand.
[0033] During specific implementation, in the normal state, when the spring scale body 1 is carried in a bag, the hook 3 for hanging heavy objects is easily bent under external force extrusion, affecting the normal use of the whole device.
[0034] In this utility model, when the user needs to place the device in a bag, the user can first rotate the limiting rod 8 into the through groove 6, and then rotate the whole hook 3 so that the hook 3 fits into the receiving groove 4 provided on the outer wall of the spring scale body 1, so that the hook 3 does not protrude outside the whole device. This makes the hook 3 not easily be squeezed during the carrying process, so that the hook 3 will not be deformed. At the same time, the hook 3 arranged in this way is not easily deformed.
[0035] When in need of use, only need to take out the hook 3 from the receiving groove 4 to use the whole device.
[0036] Meanwhile, a bolt 12 is provided on the outer wall of the spring scale body 1. Before the hook 3 fits into the receiving groove 4, the user needs to pull the limit piece 13 to pull the bolt 12 outwards so that the bolt 12 no longer restricts the rotation of the hook 3. At this time, the user can take out the hook 3 and use it. After the hook 3 fits into the receiving groove 4 again, the presence of the bolt 12 can prevent the hook 3 from disengaging from the receiving groove 4 under non-human force, so that the hook 3 can be continuously placed inside the receiving groove 4.
[0037] By arranging the hook 3 to be hinged at the bottom end of the load-bearing rod 15 and opening a receiving groove 4 adapted to the hook 3 on the outer wall of the spring scale body 1, the hook 3 can be rotated into the receiving groove 4 when not in use, so that the hook 3 is not easily damaged by external forces. While ensuring the portability of the device, the service life of the device is improved.
[0038] Working principle: In the normal state, when the spring scale body 1 is carried in a bag, the hook 3 used for hanging heavy objects is easily bent by external extrusion, affecting the normal use of the whole device.
[0039] In this utility model, when the user needs to put the device in a bag, the user can first rotate the limit rod 8 into the through groove 6, and then rotate the whole hook 3 so that the hook 3 fits into the receiving groove 4 opened on the outer wall of the spring scale body 1, so that the hook 3 does not protrude outside the whole device. This makes the hook 3 not easily squeezed during the carrying process, so that the hook 3 will not be deformed. At the same time, the hook 3 arranged in this way is not easily deformed.
[0040] When in need of use, only need to take out the hook 3 from the receiving groove 4 to use the whole device.
[0041] Meanwhile, a bolt 12 is provided on the outer wall of the spring scale body 1. Before the hook 3 fits into the receiving groove 4, the user needs to pull the limit piece 13 to pull the bolt 12 outwards so that the bolt 12 no longer restricts the rotation of the hook 3. At this time, the user can take out the hook 3 and use it. After the hook 3 fits into the receiving groove 4 again, the presence of the bolt 12 can prevent the hook 3 from disengaging from the receiving groove 4 under non-human force, so that the hook 3 can be continuously placed inside the receiving groove 4.
[0042] By arranging the hook 3 to be hinged at the bottom end of the load-bearing rod 15 and opening a receiving groove 4 adapted to the hook 3 on the outer wall of the spring scale body 1, the hook 3 can be rotated into the receiving groove 4 when not in use, so that the hook 3 is not easily damaged by external forces. While ensuring the portability of the device, the service life of the device is improved.
