[0029] Example 1

[0030] Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, provides a flat spiral grounding wire, the device comprising:

[0031] The clamping mechanism 100 includes an operating head 101, a clamping portion 102 disposed on the operating head 101, a rotating portion 103 disposed on the operating head 101, an introduction portion 104 disposed on the operating head 101 and the clamping portion 102, an extrusion portion 105 disposed on the operating head 101, a spring portion 106 disposed on the operating head 101 and the clamping portion 102, and an anti-slip portion 107 disposed on the spring portion 106;

[0032] The replacement mechanism 200 includes an insulating portion 201 , a replacement portion 202 disposed on the insulating portion 201 and connected to the rotating portion 103 , and a limiting portion 203 disposed on the rotating portion 103 .

[0033] During use, the rotating part 103 is rotated to move the clamping part 102, thereby completing the flat-mouth clamping of the clamping part 102. When double-tongue clamping is required, the introduction part 104, the squeezing part 105, and the spring part 106 are installed on the operating head 101 and the clamping part 102. The squeezing part 105 clamps the cable through the elastic force of the spring part 106, so that the device can change the clamping mode according to different use environments, thereby increasing the applicability of the device;

[0034] The insulating part 201 is rotated to drive the replacement part 202 to rotate, and the insulating part 201 is disassembled, so as to replace the clamping mechanism 100 according to different voltage levels. After the clamping mechanism 100 is replaced, the limit part 203 is moved to limit the replacement part 202, and the insulating part 201 is continued to be rotated to drive the replacement part 202 to rotate the rotating part 103, so that the clamping part 102 can be adjusted to ensure the normal use of the clamping part 102. When the introduction part 104, the extrusion part 105, and the spring part 106 are assembled, the clamping part 102 is adjusted to extrude the spring part 106, so as to adjust the elastic force of the spring part 106 and increase the applicability of the device.

[0035] Example 2

[0036] Reference Figure 1 to Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the clamping portion 102 includes a clamping plate 102a, a clamping groove 102b arranged on the clamping plate 102a, and a limiting convex strip 102c arranged on the operating head 101 and adapted to the clamping groove 102b.

[0037] Preferably, through the cooperation between the clamping groove 102b and the limiting convex strip 102c, the clamping plate 102a can slide along the side of the operating head 101, thereby ensuring the normal use of the clamping function of the clamping plate 102a.

[0038] The rotating part 103 includes a threaded sleeve 103a disposed on the operating head 101, a threaded rod 103b disposed on the threaded sleeve 103a and connected to the clamping plate 102a, and a mounting head 103c disposed on the threaded rod 103b.

[0039] Preferably, the threaded sleeve 103a is fixedly arranged on the operating head 101, the threaded rod 103b is threadedly connected to the threaded sleeve 103a, and one end of the threaded rod 103b is rotatably connected to the clamping plate 102a, so rotating the threaded rod 103b can move the clamping plate 102a to ensure normal use of the device.

[0040] The introduction portion 104 includes an introduction installation piece 104a disposed on the operating head 101 and the clamping plate 102a, an introduction arc spring piece 104b disposed on the introduction installation piece 104a, and an introduction card 104c disposed on the introduction arc spring piece 104b.

[0041] Preferably, two introduction mounting pieces 104a are provided, one is fixed to the clamping plate 102a by bolts, and the other is fixed to the end of the opening of the operating head 101 by bolts, so that the two introduction parts 104 are arranged in a mirror image, so that the cable can enter the extrusion part 105 through the introduction arc spring piece 104b, which is convenient for the cable to be inserted. The setting of the introduction card 104c not only ensures that the cable can enter the extrusion part 105, but also limits the extrusion part 105 to prevent the two extrusion parts 105 from fitting closely. If the two extrusion parts 105 fit closely, the cable will not be able to enter the interior of the extrusion part 105, affecting the use of the device. Moreover, due to the setting of the introduction card 104c, when the cable squeezes the two introduction arc spring pieces 104b to expand, it can drive the introduction card 104c to make the two extrusion wave plates 105c move away from each other, which is convenient for the entry of the cable.

[0042] The extrusion part 105 includes an extrusion mounting plate 105a disposed on the limiting convex strip 102c, an extrusion chute 105b disposed on the extrusion mounting plate 105a and adapted to the limiting convex strip 102c, and an extrusion corrugated plate 105c disposed on the extrusion mounting plate 105a.

[0043] Preferably, the extrusion mounting plate 105a is slidably connected to the limiting convex strip 102c through the extrusion slide groove 105b, so that the extrusion mounting plate 105a can move, thereby ensuring the clamping function of the device. The extrusion wave plate 105c is arranged in a wave shape, so that the extrusion wave plate 105c has multiple notches, which can increase the contact area with the cable, thereby increasing the clamping stability. One end of the extrusion wave plate 105c is in close contact with the import card 104c, so that the import card 104c can drive the extrusion wave plate 105c to move.

[0044] The spring piece portion 106 includes a spring piece installation section 106a disposed on the operating head 101 and the clamping plate 102a, a spring piece bending section 106b disposed on the spring piece installation section 106a, and a spring piece contact section 106c disposed on the spring piece bending section 106b.

[0045] Preferably, the spring installation section 106a facilitates the installation and removal of the spring part 106, the bending of the spring bending section 106b provides clamping force for clamping, and the spring contact section 106c increases the contact area with the extruded wave plate 105c, so that the extruded wave plate 105c is subjected to more uniform force and the clamping is more stable.

[0046] The anti-dropout portion 107 includes an anti-dropout pin rod 107a disposed on the spring sheet abutting section 106c, and an anti-dropout pin hole 107b disposed on the extruded wave plate 105c and matched with the anti-dropout pin rod 107a.

[0047] Preferably, one end of the anti-slip pin hole 107b is fixedly set at the recess of the extruded wave plate 105c, so that the extruded wave plate 105c can be engaged with the spring portion 106 to prevent the extruded wave plate 105c from falling off, thereby ensuring the normal use of the device. If the anti-slip portion 107 is not provided, the extruded mounting plate 105a may be separated from the limiting convex strip 102c, which is more dangerous.

[0048] The remaining structures are the same as those of Example 1.

[0049] During use, when the clamping plate 102a needs to be used to directly perform a clamping operation, due to the limit convex strip 102c limiting the clamping plate 102a, the threaded rod 103b is rotated to drive the clamping plate 102a to move, and the clamping plate 102a moves to clamp the cable to complete the clamping operation;

[0050] When double-tongue clamping is required, the spring piece installation section 106a is fixed to the operating head 101 and the clamping plate 102a respectively by bolts, the anti-dropout pin hole 107b is inserted into the anti-dropout pin rod 107a, and the extrusion slide groove 105b is clamped with the limiting convex strip 102c to complete the assembly of the spring piece part 106 and the extrusion part 105, and the introduction installation piece 104a is fixed to the operating head 101 and the clamping plate 102a by bolts, thereby completing the assembly of the introduction part 104, and the threaded rod 103b is rotated to drive the clamping plate 102a to make the two spring piece contact sections 106c approach each other, thereby adjusting the elastic force of the spring piece contact section 106c, and the cable slides into the recess of the extrusion wave plate 105c through the introduction arc spring piece 104b and the introduction card 104c to complete the cable clamping operation.

[0051] Example 3

[0052] Reference Figure 1 , Figure 4 and Figure 5, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the insulating part 201 includes an insulating rod 201a and an insulating handle 201b arranged on the insulating rod 201a.

[0053] Preferably, the insulating rod 201a is made of insulating material, and the insulating handle 201b is made of rubber.

[0054] The replacement part 202 includes a replacement thread head 202a disposed on the insulating rod 201a, and a replacement internal thread 202b disposed in the mounting head 103c and matched with the replacement thread head 202a.

[0055] Preferably, the threaded head 202a is replaced and fixedly arranged at one end of the insulating rod 201a. Due to the replacement setting of the internal thread 202b, the insulating rod 201a is convenient to be assembled with the clamping mechanism 100, thereby facilitating the replacement of the clamping mechanism 100. Currently, most of the flat-mouth spiral operating heads on the market are fixed in design because the clamping plate 102a needs to be adjusted through the insulating rod 201a.

[0056] The limiting portion 203 includes a limiting cap 203a disposed on the mounting head 103c, a limiting rod 203b disposed on the limiting cap 203a, and a limiting hole 203c disposed on the replacement threaded head 202a and matched with the limiting rod 203b.

[0057] Preferably, the limiting cap 203a is designed in a cap shape and a through hole is provided at the center. The cap-shaped design facilitates the limiting cap 203a to move along the mounting head 103c. If it is designed in an annular shape, it is difficult to separate the limiting cap 203a and the mounting head 103c after they are fitted together. The through hole at the center facilitates the limiting cap 203a to move along the threaded rod 103b to prevent jamming. Several limiting rods 203b are provided, and one end of the limiting rod 203b passes through the mounting head 103c and extends to the interior of the mounting head 103c. Through the provision of the limiting hole 203c, the limiting rod 203b can limit the replacement of the threaded head 202a. After the limiting rod 203b is inserted into the limiting hole 203c, whether the insulating rod 201a is rotated clockwise or counterclockwise, it can stably drive the threaded rod 103b to rotate, thereby realizing the movement of the clamping plate 102a and completing the clamping operation or the elastic force adjustment operation.

[0058] The remaining structure is the same as that of Example 2.

[0059] During use, when the clamping mechanism 100 of a different voltage level needs to be replaced, the limit cap 203a is rotated to move the limit rod 203b away from the limit hole 203c, thereby releasing the limit on the replacement thread head 202a, and the insulating rod 201a is rotated to drive the replacement thread head 202a to rotate, so that the clamping mechanism 100 is disassembled and replaced;

[0060] When the position of the clamping plate 102a needs to be adjusted, the limit cap 203a is moved to drive the limit rod 203b to be inserted into the limit hole 203c, thereby limiting the replacement of the threaded head 202a, and the insulating rod 201a is rotated to drive the replacement threaded head 202a to rotate the installation head 103c, and the installation head 103c drives the threaded rod 103b to rotate. The rotation of the threaded rod 103b drives the clamping plate 102a to move, thereby adjusting the clamping plate 102a, which not only ensures the normal clamping of the clamping plate 102a, but also can adjust the elastic force of the spring bending section 106b by the movement of the clamping plate 102a.
