[0034] Figure 1 FIG. is a schematic view of a handheld spring hanging tool 100 clamping a spring 30 according to one embodiment of the present application. Figure 2 is Figure 1 a schematic view of the handheld spring hanging tool 100 in Figure 2 wherein Figure 1 the spring 30 in Figure 3 is Figure 2Exploded view of the handheld spring mounting tool 100 in

[0035] Please refer to Figures 1 to 3 , in some alternative embodiments, the handheld spring mounting tool 100 includes a plier mechanism 10 and a fixture 20.

[0036] The plier mechanism 10 has a first connection end 111 and a second connection end 121 spaced apart in the width direction on the same side in the length direction. Both the first connection end 111 and the second connection end 121 are connected to a fixture 20, and the fixture 20 forms a variable opening C for clamping a spring 30.

[0037] The fixture 20 is configured to be able to adjust the size of the variable opening C to fit springs 30 of different specifications, and the plier mechanism 10 is configured to be able to adjust the spacing between the first connection end 111 and the second connection end 121 in the width direction to drive the spring 30 held by the fixtures 20 at both ends to change its length.

[0038] In this embodiment, the handheld spring mounting tool 100 at least includes a plier mechanism 10 and a fixture 20. Among them, the plier mechanism 10 has two connection ends formed on the same side in the length direction, corresponding to the first connection end 111 and the second connection end 121 respectively. The first connection end 111 and the second connection end 121 are spaced apart in the width direction, and the plier mechanism 10 is configured to be able to adjust the spacing between the first connection end 111 and the second connection end 121 in the width direction.

[0039] Fixtures 20 are provided on both the first connection end 111 and the second connection end 121. The fixtures 20 are used to clamp the spring 30. Specifically, the fixture 20 forms a variable opening C, and the spring 30 is clamped in the variable opening C.

[0040] The fixtures 20 on the two connection ends can respectively clamp both ends of the spring 30. By adjusting the spacing between the first connection end 111 and the second connection end 121 in the width direction by the plier mechanism 10, correspondingly, the spacing between the two fixtures 20 on the first connection end 111 and the second connection end 121 changes, and thus the length of the spring 30 clamped by the fixtures 20 changes.

[0041] In this way, the assembler can use the handheld spring mounting tool 100 to adjust the expansion and contraction of the spring 30, facilitating the quick installation of the spring 30. And during the process of adjusting the expansion and contraction of the spring 30, the assembler does not need to directly contact the spring 30. Even if the spring 30 rebounds due to being not firmly installed during the assembly process, it will not hurt the hand, reducing the assembly risk. Moreover, since the size of the variable opening C in the fixture 20 is adjustable and can fit springs 30 of different specifications, the versatility of the handheld spring mounting tool 100 can be further improved.

[0042] It should be noted that, in the illustrated embodiment, the number of the jigs 20 is two, and they are respectively installed at the first connection end 111 and the second connection end 121. Thus, only one spring 30 can be assembled at a time. It should be noted that the jigs 20 can be arranged in pairs, that is, an even number, and are not limited to the illustrated embodiment. For example, they can also be four, six, etc. Thus, more than two springs 30 can be assembled at a time.

[0043] Figure 4 is Figure 3 a schematic diagram of the jig 20 in. Please refer to Figure 3 and Figure 4 In a further optional embodiment, the jig 20 includes a fixed clamping plate 21, a movable clamping plate 22, an adjusting member 23, and a jig pivot shaft 24.

[0044] The fixed clamping plate 21 and the movable clamping plate 22 are hinged through the jig pivot shaft 24, and a variable opening C is formed between the fixed clamping plate 21 and the movable clamping plate 22.

[0045] The fixed clamping plate 21 is connected to the pliers mechanism 10. The adjusting member 23 passes through the fixed clamping plate 21 and the movable clamping plate 22 and is used to control the pivoting angle of the movable clamping plate 22 relative to the fixed clamping plate 21 to adjust the size of the variable opening C.

[0046] In this embodiment, the jig 20 at least includes a fixed clamping plate 21, a movable clamping plate 22, an adjusting member 23, and a jig pivot shaft 24. Among them, the fixed clamping plate 21 and the movable clamping plate 22 are hinged through the jig pivot shaft 24, and the fixed clamping plate 21 is connected to the pliers mechanism 10. Thus, the movable clamping plate 22 can rotate relative to the fixed clamping plate 21.

[0047] In addition, a variable opening C is formed between the fixed clamping plate 21 and the movable clamping plate 22. During the process of the movable clamping plate 22 rotating relative to the fixed clamping plate 21, it is the process of changing the size of the variable opening C. Further, the movable clamping plate 22 can be locked by the adjusting member 23, so as to determine the pivoting angle between the movable clamping plate 22 and the fixed clamping plate 21, that is, to complete the adjustment of the size of the variable opening C.

[0048] In a specific application, the adjusting member 23 can be a screwed member, including, for example, bolts, screws, etc. Preferably, the adjusting member 23 can adopt a non-loosening screw.

[0049] It can be understood that when it is necessary to clamp the spring 30, the adjusting member 23 can be screwed out, and the movable clamping plate 22 is rotated away from the fixed clamping plate 21 to increase the variable opening C, so that the spring 30 can be placed into the variable opening C. Then, the adjusting member 23 is screwed in, so that the movable clamping plate 22 rotates close to the fixed clamping plate 21, and the variable opening C can be reduced, thereby completing the clamping of the spring 30. Obviously, the jig 20 can be adapted to clamp springs 30 of different specifications.

[0050] In a further optional embodiment, both the fixed clamping plate 21 and the movable clamping plate 22 include a straight plate section 201 and an arc plate section 202, and the arc plate section 202 extends downward from the straight plate section 201.

[0051] A variable opening C is formed between the arc plate sections 202 of the fixed clamping plate 21 and the movable clamping plate 22. The fixture pivot shaft 24 is located at the junction of the straight plate section 201 and the arc plate section 202, and the adjusting member 23 passes through the straight plate sections 201 of the fixed clamping plate 21 and the movable clamping plate 22.

[0052] In this embodiment, both the fixed clamping plate 21 and the movable clamping plate 22 have a straight plate section 201 and an arc plate section 202. Specifically, the shapes of the fixed clamping plate 21 and the movable clamping plate 22 are similar. The arc plate section 202 extends from the straight plate section 201 and is located below the straight plate section 201. The variable opening C is formed between the arc plate sections 202 of the fixed clamping plate 21 and the movable clamping plate 22.

[0053] The fixture pivot shaft 24 passes through the splicing joint of the fixed clamping plate 21 and the movable clamping plate 22 to hinge the fixed clamping plate 21 and the movable clamping plate 22, so that the movable clamping plate 22 is rotatably connected to the fixed clamping plate 21. Moreover, the splicing joint of the fixed clamping plate 21 is the junction of its straight plate section 201 and arc plate section 202, and the splicing joint of the movable clamping plate 22 is the junction of its straight plate section 201 and arc plate section 202.

[0054] The adjusting member 23 passes through the straight plate sections 201 of the two clamping plates, and the variable opening C is formed in the arc plate sections 202 of the two clamping plates. Therefore, the adjusting member 23 and the variable opening C are respectively located on the upper and lower sides of the fixture pivot shaft 24. By controlling the pivot angle between the straight plate sections 201 of the two clamping plates through the adjusting member 23, the size of the variable opening C is correspondingly adjusted.

[0055] Since the variable opening C is formed between the arc plate sections 202 of the two clamping plates, the variable opening C is a circular opening. Correspondingly, adjusting the size of the variable opening C can refer to adjusting the maximum diameter of the variable opening C.

[0056] In a further optional embodiment, both the fixed clamping plate 21 and the movable clamping plate 22 include a buffer pad 203. The buffer pad 203 is attached to the arc plate section 202 and is located on one side of the variable opening C.

[0057] In this embodiment, for the same fixture 20, buffer pads 203 are provided on the inner sides of the arc plate sections 202 of its two clamping plates. Through the buffer pads 203, the two clamping plates can be in flexible contact with the spring 30, avoiding damage to the spring 30, and also increasing the friction force and reducing the risk of relative sliding between the fixture 20 and the spring 30.

[0058] In a specific application, the buffer pad 203 can be attached to the inner side of the arc plate segment 202 by gluing or other processes, and of course, can also be detachably connected to the splint by Velcro, screw connectors, etc. The buffer pad 203 here can be made of elastic plastic, silicone, or other materials.

[0059] In some optional embodiments, the clamp mechanism 10 includes a first rod group 11 and a second rod group 12. The first rod group 11 and the second rod group 12 are hinged, and the same end of the first rod group 11 and the second rod group 12 in the length direction corresponds to a first connecting end 111 and a second connecting end 121.

[0060] The fixing clamp plate 21 is provided with a connecting block 211 located on the straight plate section 201 , and the first connecting end 111 and the second connecting end 121 can be hingedly matched with the connecting block 211 on the corresponding fixing clamp plate 21 .

[0061] In this embodiment, the clamp mechanism 10 may be formed by hingedly connecting two rod groups, which correspond to a first rod group 11 and a second rod group 12 respectively, so that the first rod group 11 and the second rod group 12 can rotate relative to each other.

[0062] One end of the first rod group 11 corresponds to the first connecting end 111, and the end on the same side as the first connecting end 111 in the second rod group 12 corresponds to the second connecting end 121. A connecting block 211 is provided at the straight plate section 201 of each fixed clamp 21 in each clamp 20, and the connecting block 211 in each clamp 20 is hingedly matched with the corresponding connecting end of the clamp mechanism 10.

[0063] In other words, the clamp 20 is movably connected to the clamp mechanism 10 . Specifically, the clamp 20 can swing relative to the clamp mechanism 10 , so that the spring 30 can be prevented from bending during the stretching process.

[0064] Figure 5 for Figure 3 See the exploded view of the clamp mechanism 10 in FIG. Figure 5 In a further optional embodiment, the first rod group 11 and the second rod group 12 both include a hand-held rod 101 and a transfer rod 102, and the hand-held rod 101 and the transfer rod 102 are spliced ​​in the length direction;

[0065] One end of the transfer rod 102 in the first rod group 11 away from the hand-held rod 101 is a first connection end 111 , and one end of the transfer rod 102 in the second rod group 12 away from the hand-held rod 101 is a second connection end 121 .

[0066] In this embodiment, the first rod group 11 and the second rod group 12 both adopt similar structures, and specifically, both rod groups are spliced ​​structures of the hand-held rod 101 and the transfer rod 102. In addition, the connection ends are both ends of the transfer rod 102, specifically, the first connection end 111 is the end of the transfer rod 102 in the first rod group 11 away from the hand-held rod 101, and the second connection end 121 is the end of the transfer rod 102 in the second rod group 12 away from the hand-held rod 101.

[0067] In a specific application, the hand-held rod 101 is detachably connected to the adapter rod 102. In this way, it is convenient to disassemble, does not take up space for storage, and is conducive to replacing the maintenance fixture 20.

[0068] In the illustrated embodiment, the hand-held rod 101 is threadedly connected to the transfer rod 102, a stud is provided at one end of the transfer rod 102 close to the hand-held rod 101, and a threaded hole is provided at one end of the hand-held rod 101 close to the transfer rod 102, and the two are threadedly connected. Of course, it is not limited to the illustrated embodiment.

[0069] In a further optional embodiment, the transfer rod 102 is provided with a splicing groove D, which is located at the connecting end and can accommodate the connecting block 211 .

[0070] The clamp mechanism 10 further includes a first latch 103 , which passes through the connection end and the connection block 211 located in the splicing groove D.

[0071] In this embodiment, the transfer rod 102 has a splicing groove D, which is located at the end of the transfer rod 102 away from the hand-held rod 101, that is, at the connection end of the clamp mechanism 10. The splicing groove D is used to receive the connection block 211 on the fixed clamp plate 21.

[0072] Furthermore, the clamp mechanism 10 also has a first latch 103, through which the connection end can be connected to the connection block 211 received in the splicing groove D, that is, the clamp 20 and the connection end are hinged.

[0073] In a further optional embodiment, the hand-held rod 101 includes a rod body 1011 and an ear plate 1012 , and the ear plate 1012 extends from the rod body 1011 along the width direction.

[0074] The clamp mechanism 10 further includes a second latch pin 104 . The ear plate 1012 on the first rod group 11 and the ear plate 1012 on the second rod group 12 are spliced ​​in the width direction and penetrated by the second latch pin 104 .

[0075] In this embodiment, the handheld rod 101 comprises a rod body 1011 and an ear plate 1012, wherein the ear plate 1012 is located at one side of the width direction of the rod body 1011. As can be seen from the foregoing, the first rod group 11 and the second rod group 12 are both spliced ​​structures of the handheld rod 101 and the adapter rod 102.

[0076] That is, both the first link group 11 and the second link group 12 are provided with corresponding ear plates 1012. Further, the clamping mechanism 10 is further provided with a second pin 104, and the second pin 104 connects the ear plate 1012 of the first link group 11 and the ear plate 1012 of the second link group 12 to realize the hinge connection between the first link group 11 and the second link group 12.

[0077] In this way, the first link group 11 and the second link group 12 can rotate relative to each other with the second pin 104 as the pivot axis, thereby driving the fixture 20 located at the first connection end 111 and the fixture 20 located at the second connection end 121 to move relative to each other in the width direction, so as to stretch the spring 30 clamped between the two fixtures 20 to assist in assembly.

[0078] Please refer to Figure 2 , in a further optional embodiment, the distance between the second pin 104 and the end of the rod body 1011 away from the fixture 20 in the length direction is a first distance L1.

[0079] The distance between the second pin 104 and the fixture 20 in the length direction is a second distance L2, and the first distance L1 is greater than the second distance L2.

[0080] In this embodiment, when the first link group 11 and the second link group 12 are hinged, a lever with the second pin 104 as the fulcrum is formed. Among them, the first distance L1 is the force arm, and the second distance L2 is the resistance arm. The first distance L1 is greater than the second distance L2, that is, it ensures that the force arm is greater than the resistance arm, which is more convenient for the assembler to operate.

[0081] In summary, through the handheld spring hanging tool 100 provided by the present application, it is convenient for the assembler to stretch the spring 30 to complete the assembly of the spring 30 and reduces the risk of injury caused by the stretching of the spring 30. Moreover, the handheld spring hanging tool 100 can adapt to different specifications of the spring 30 and has good versatility.

Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
