[0030] Figure 1 is the overall structure schematic diagram of the clamp of the embodiment of the present application. Referring to Figure 1The clamp of the embodiment comprises a first part 10, a second part 20 and an elastic member 30. The first part 10 comprises an angularly arranged first handle 11 and a first clamping part 12, and the second part 20 comprises an angularly arranged second handle 21 and a second clamping part 22. The first clamping part 12 is arranged at a first end of the first handle 11, the second part 20 is rotationally arranged at a second end of the first handle 11, and the second handle 21 is below the first handle 11. The elastic member 30 is connected between the first part 10 and the second part 20. When the second handle 21 rotates relative to the first handle 11 and the second handle 21 approaches the first handle 11, the second clamping part 22 also rotates relative to the first handle 11 and moves towards the first clamping part 12. When the first clamping part 12 and the second clamping part 22 approach each other, the distance between them is reduced, thereby being able to clamp the module on the ammeter. At the same time, the elastic member 30 deforms to generate a driving force that can drive the first part 10 and the second part 20 to reset.

[0031] When using the clamp, the operator controls the clamp through the first handle 11 and the second handle 21 to align the ends of the first clamping part 12 and the second clamping part 22 with the grooves on both sides of the module. Since the first handle 11 and the second handle 21 are arranged above and below each other, the operator can control the first handle 11 to rotate relative to the second handle 21 by gripping the palm or pinching up and down, thereby driving the second clamping part 22 to rotate and approach the first clamping part 12. The first clamping part 12 and the second clamping part 22 approach each other to firmly clamp the module, and then the operator can pull out the module. When the operator releases his hand, the elastic member 30 can drive the first part 10 and the second part 20 to rotate and reset relative to each other for the next operation. The clamp has a simple structure and is easy to operate, effectively avoids long-time pressing of the fingers, greatly reduces the burden of the operator, and improves the work efficiency.

[0032] Reference Figure 1 A first abutting part 13 is arranged at an end of the first clamping part 12 away from the first handle 11. A second abutting part 23 is arranged at an end of the second clamping part 22 away from the second handle 21. The first abutting part 13 is bent upwards towards the second clamping part 22, and the second abutting part 23 is bent upwards towards the first clamping part 12. When the first clamping part 12 and the second clamping part 22 approach each other, the first abutting part 13 and the second abutting part 23 abut in the grooves on both sides of the module, respectively, and tightly abut with the groove walls to firmly clamp the module. The bent first abutting part 13 and the second abutting part 23 can be clamped with the protrusions in the module grooves when the module is pulled upwards, further ensuring the connection strength between the clamp and the module when the module is pulled out.

[0033] Further, the first abutting portion 13 and the second abutting portion 23 have a predetermined thickness respectively to increase the contact area of the first abutting portion 13 and the second abutting portion 23 with the module. The contact surface of the first abutting portion 13 with the groove and the contact surface of the second abutting portion 23 with the groove are both vertically arranged, which can better fit the groove wall to increase the stress area and enhance the clamping force. Alternatively, the thickness can be adjusted according to the groove depth of the module to be disassembled to adapt to different modules. In addition, the inner side of the first abutting portion 13 and the inner side of the second abutting portion 23 are provided with anti-skid pads respectively, which can effectively increase the friction and prevent the clamp from disengaging from the module during pulling.

[0034] When the first clamping portion 12 and the second clamping portion 22 are close to each other, one end of the second clamping portion 22 connected with the second handle 21 is fixed, and the other end provided with the second abutting portion 23 is relatively swung and close to the first clamping portion 12. Referring to Figure 1 , the second end of the first handle 11 is bent downward to form a connecting portion 15. The junction of the second handle 21 and the second clamping portion 22 is rotationally connected with the connecting portion 15 through a connecting piece 40. At the same time, the second handle 21 is located below the first handle 11, and the second handle 21 is spaced apart from the first handle 11 by a certain distance through the connecting portion 15, leaving space for the rotation of the second handle 21. The second handle 21 and the second clamping portion 22 are fixedly connected, and when the operator controls the position of the second handle 21 relative to the connecting piece 40 to rotate, the second clamping portion 22 is simultaneously driven to rotate relative to the position of the connecting piece 40, and then the second abutting portion 23 is close to the first abutting portion 13 to clamp the module. Alternatively, the connecting piece 40 can be provided as a bolt, a pin shaft or a hinge connecting device.

[0035] Further, the first handle 11 and the second handle 21 are arranged relatively parallel, and the first handle 11 and the second handle 21 are arranged in the same direction, which is convenient for the operator to grasp and control. The parallel arrangement between the first handle 11 and the second handle 21 can save the operating force in the vertical direction when the operator pulls, thereby reducing the operating fatigue. In addition, the first clamping portion 12 is perpendicular to the first handle 11, and the second clamping portion 22 is perpendicular to the second handle 21. The length of the second handle 21 is less than the length of the first handle 11, and the first clamping portion 12 and the second clamping portion 22 are arranged at both ends of the first handle 11 and the second handle 21. That is, the first clamping portion 12 and the second clamping portion 22 are symmetrically arranged relative to the first handle 11. The symmetrical structure can improve the balance of the clamp during use and improve the control accuracy of the operator on the clamp. At the same time, the symmetrical structure also helps to ensure that the force applied to the module during clamping is uniformly distributed, thereby improving the stability of clamping.

[0036] Further, the end of the first clamping part 12 is inwardly bent to be provided with a first bent part 14, and the first abutting part 13 is arranged at one end of the first bent part 14 away from the first clamping part 12. The end of the second clamping part 22 is inwardly bent to be provided with a second bent part 24, and the second abutting part 23 is arranged at one end of the second bent part 24 away from the second clamping part 22. The arrangement of the first bent part 14 and the second bent part 24 makes the distance between the first clamping part 12 and the second clamping part 22 and the distance between the first abutting part 13 and the second abutting part 23 be able to be set according to specific requirements. For example, the distance between the first clamping part 12 and the second clamping part 22 can be set according to the use mode and use habit of the operator, and the distance between the first abutting part 13 and the second abutting part 23 can be set according to the size of the groove between the two sides of the to-be-pulled module, effectively improving the practicability and portability of the clamp.

[0037] Further, the first bent part 14 is arranged perpendicularly to the first clamping part 12, and the second bent part 24 is arranged perpendicularly to the second clamping part 22, which helps to improve the connection strength and structural strength between the structures. At the same time, the perpendicular arrangement makes the force transmission path more direct, effectively guaranteeing the stability of the force exerted when the module is clamped, and further improving the reliability of the clamp. In addition, the first bent part 14 and the second bent part 24 are arranged along the same line, so that the structures at both ends of the first handle 11 are symmetrically arranged, thereby guaranteeing that the force exerted by the clamp on the two sides of the module is uniformly distributed, so as to improve the clamping force.

[0038] Further, the two ends of the elastic member 30 are respectively connected with the second handle 21 and the first bent part 14. When the second handle 21 rotates towards the first handle 11, the distance between the second handle 21 and the first bent part 14 increases, so that the elastic member 30 deforms, thereby generating a driving force for driving the second handle 21 and the second clamping part 22 to reset. Figure 1 The elastic member 30 is arranged relatively parallel to the first clamping part 12 and the second clamping part 22. That is, the elastic member 30 is arranged vertically between the second handle 21 and the first bent part 14 to reduce the force transmission path and provide stability of the elastic member 30. Alternatively, the elastic member 30 of the present embodiment can be a tension spring or an elastic rope that can elastically deform in a stretched state.

[0039] In an alternative embodiment, the elastic member 30 is arranged between the first handle 11 and the second handle 21. In the present embodiment, the first handle 11 and the second handle 21 can compress the elastic member 30 when they are relatively close, so that the elastic member 30 elastically deforms to provide a reset driving force. The elastic member 30 of the present embodiment can be arranged as a compression spring.

[0040] In another alternative embodiment, the elastic member 30 is arranged between the second handle 21 and the connecting portion 15. When the second handle 21 rotates relative to the connecting portion 15, the elastic member 30 is compressed to be elastically deformed, and the elastic member 30 can provide a reset driving force. The elastic member 30 in this embodiment can be a torsion spring.

[0041] The clamp provided by the embodiment can be clamped to the module by rotating the first handle and the second handle, so that the operator can control the clamp to clamp and pull the module by a simple gripping or pinching action. The parallel arrangement between the first handle and the second handle can save the operating strength of the operator when pulling, reduce the operating fatigue of the operator, and the elastic member arranged between the first portion and the second portion can automatically reset the clamp, thereby significantly improving the work efficiency.

[0042] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
