[0002] like Figure 1 The spring clamp 4 shown includes a base 41, a rotating shaft 42, a control rod 43, and a spring 44. The control rod 43 is rotatably mounted on the base 41 via the rotating shaft 42, and the spring 44 is sleeved on the rotating shaft 42. The spring 44 is bent to form a control slot 45, and the control rod 43 is inserted into the control slot 45. This spring clamp 4 achieves corresponding movement by pressing the control rod 43 to rotate. After releasing the control rod 43, the control rod 43 returns to its original position under the reset action of the spring 44. Specifically, the spring 44 in the spring clamp 4 is preferably a torsion spring.

[0003] After a period of use, the spring 44 will wear out, causing its performance to deteriorate, requiring replacement of the spring 44. However, conventional methods for replacing the spring 44 typically involve disassembling the entire spring fixture 4 before replacing the spring. During installation, the two ends of the spring must be bent until they contact the inner bottom wall of the base 41. Because the force of the spring 44 is very strong and the width of the base 41 is significantly greater than the length of the spring 44, the bending process requires significant time and labor costs, making replacement very inefficient.

DETAILED DESCRIPTION

[0035] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the embodiments and the accompanying drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 7As shown, the present invention provides a spring clamp tool for replacing a spring, including a first fastener 1 and a second fastener 2. The first fastener 1 is provided with a buckle groove 13, and the second fastener 2 is provided with a make way groove 25 for making way for the spring 44. The second fastener 2 is installed on the first fastener 1, and the bottom of the make way groove 25 can be detachably installed in the buckle groove 13. The top of the make way groove 25 is provided with a resistance part 21 for resisting the two ends of the spring 44, and the width of the resistance part 21 is not greater than the length of the spring 44.

[0037] Specifically, the structure of the spring clamp 4 is as follows Figures 1 to 3 As shown, it has a base 41, a rotating shaft 42, a control rod 43 and a spring 44. The control rod 43 is rotatably set on the base 41 via the rotating shaft 42, and the spring 44 is sleeved on the rotating shaft 42; the spring 44 is bent to form a control groove 45, and the control rod 43 is inserted into the control groove 45.

[0038] The method of use of the present invention is:

[0039] EX. Disassemble the spring clamp 4, remove the old spring 44 of the spring clamp 4, and replace it with the spring 44 that needs to be installed later.

[0040] A. Install spring 44 into the clearance groove 25;

[0041] B. Install the control rod 43 on the second fastener 2 and insert the control rod 43 into the control slot 45 of the spring 44;

[0042] C. Fasten the first fastener 1 and the second fastener 2;

[0043] D. Bend both ends of the spring 44 between the first fastener 1 and the abutment portion 21 so that both ends of the spring 44 abut against the abutment portion 21 under stress;

[0044] E. Install the second fastener 2 on the base 41;

[0045] F. Install the shaft 42 to the base 41 so that it passes through the spring 44 from one end of the base 41 and protrudes from the other end of the base 41;

[0046] G. Remove the first fastener 1 and the second fastener 2.

[0047] That is, compared with the prior art, the present invention first assembles the spring 44 and the control rod 43 on the second fastener 2, and then covers the second fastener 2 with the first fastener 1 to fix the posture of the spring 44 and the control rod 43, and then uses a hollow rod to cover one end of the spring 44 to increase the force arm, so as to facilitate the bending of the spring 44. In this way, the two ends of the spring 44 are respectively bent from the two sides of the interference part 21 to the position between the first fastener 1 and the interference part 21, and then the hollow rod is released, so that the two ends of the spring 44 can be limited by the interference part 21. At this time, the base 41 and the rotating shaft 42 are installed and the first fastener 1 and the second fastener 2 are removed, and the two ends of the spring 44 are in the base 41.

[0048] The structure and method of the present invention are ingenious. After the first fastener 1 and the second fastener 2 are positioned once, the spring 44 can be more easily bent into the interference portion 21, and then the base 41 can be installed. Compared with the method of directly bending the spring 44 to install it on the base 41, it is better in terms of time and manpower, and improves the efficiency of replacing the spring 44.

[0049] In this embodiment, the first fastener 1 includes a main body 11 and a buckle portion 12. The buckle portion 12 is provided at one end of the main body 11. The buckle portion 12 is connected to one side of the main body 11 and is recessed inward to form a buckle groove 13. A limiting portion 16 is provided at the other end of the main body 11. The limiting portion 16 cooperates with the buckle portion 12 to limit the position of the second fastener 2.

[0050] A gap 14 is formed between the resisting portion 21 and the buckling portion 12 .

[0051] That is, in addition to cooperating with the clearance groove 25 to achieve the positioning of the first fastener 1 and the second fastener 2, the buckle portion 12 of the first fastener 1 is also used to cooperate with the limiting portion 16 to realize the assembly of the second fastener 2, so that the second fastener 2 and the first fastener 1 are not installed, thereby achieving the fixation of the spring 44 and the control rod 43.

[0052] Specifically, the main body 11 is provided with a first avoidance groove 15, which is used to make way for the spring clamp 4. The first avoidance groove 15 mainly avoids the control rod 43 to facilitate the subsequent removal of the first mouthpiece and the second fastener 2 from the spring clamp 4. The position other than the first avoidance groove 15 is aligned with the interference point between the control rod 43 and the control groove 45. The first fastener 1 and the second fastener 2 fix this position to facilitate the subsequent insertion of the rotating shaft 42.

[0053] In this embodiment, the give way groove 25 is arranged at one end of the second fastener 2, and the second fastener 2 is penetrated by a second avoidance groove 22, and the second avoidance groove 22 is used to give way to the spring clamp 4; anti-falling parts 23 are respectively provided on both sides of the second fastener 2, and the anti-falling parts 23 are used to prevent the spring 44 located in the give way groove 25 from escaping from the give way groove 25 from both sides.

[0054] The anti-falling portion 23 can be formed by protruding upwards on both sides of the second fastener 2. The two anti-falling portions 23 cooperate to reliably position the spring 44 to prevent it from falling off.

[0055] In this embodiment, the resisting portion 21 is fixedly connected to the second fastener 2 . A positioning portion 24 is provided at one end of the resisting portion 21 close to the second fastener 2 . Both sides of the positioning portion 24 are used to resist the spring 44 .

[0056] Specifically, the spring 44 described in this embodiment has two spiral portions 46, and the control groove 45 is located between the two spiral portions 46; and in step A, the positioning portion 24 is arranged corresponding to the control groove 45, and the positioning portion 24 is located between the two spiral portions 46. By clamping the positioning portion 24 between the two spiral portions 46, the spring 44 can be effectively prevented from being offset, thereby ensuring the assembly effect.

[0057] In this embodiment, the present invention further includes a rotating shaft 42, which is inserted into a spring 44 located within the clearance groove 25 for positioning. Specifically, the rotating shaft 42 is inserted into the buckle groove 13 after the first fastener 1 is engaged with the second fastener 2, and is limited in position by the gap between the buckle groove 13 and the clearance groove 25.

[0058] That is, between steps B and C, step B' is also included. A shaft 42 is mounted on one end of the second fastener 2, and the shaft 42 passes through the spring 44 and then protrudes from the other end of the second fastener 2. The shaft 42 acts as a series connection between the spring 44 and the control rod 43, allowing the two to be relatively fixed. The ends of the spring 44 are then bent into the gap 14, ensuring that the spring 44 does not move due to uneven force during the bending process.

[0059] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention are all within the scope of the technical solution of the present invention without departing from the content of the technical solution of the present invention.
