[0024] See also Figure 1 Combined with Figure 2 The tightening tool 1000 includes a first pliers body 1, a second pliers body 2, a clamping portion 3, a labor-saving device 4 and an elastic member 5. The first pliers body 1 and the second pliers body 2 are cross-arranged, and the first pliers body 1 and the second pliers body 2 are rotatably connected. The clamping portion 3 is arranged at one end of the first pliers body 1 and the second pliers body 2, the labor-saving device 4 is located at the intersection of the first pliers body 1 and the second pliers body 2, the elastic member 5 is located between the first pliers body 1 and the second pliers body 2, and the elastic member 5 is located on one side near the intersection of the first pliers body 1 and the second pliers body 2.

[0025] In some embodiments, the labor-saving device 4 can be a ratchet and a transmission gear. The ratchet and the transmission gear are arranged at the intersection of the first pliers body 1 and the second pliers body 2, and the force transmission is realized through the meshing between the gears. The number of teeth of the gears can also be proportionally set according to relevant actual work needs, so as to achieve a deceleration effect and avoid excessive force applied to the first pliers body 1 and the second pliers body 2 during manual operation, causing the first pliers body 1 and the second pliers body 2 to approach each other too quickly, thereby causing damage to the gold-plated connectors.

[0026] In some embodiments, the rotational connection method at the intersection of the first pliers body 1 and the second pliers body 2 includes but is not limited to the following connection methods: a rotation hole may be opened at the intersection of the first pliers body 1 and the second pliers body 2, and a bearing is provided at the rotation hole for rotation, or the labor-saving device is provided at the rotation hole at the intersection of the first pliers body 1 and the second pliers body 2 to realize rotation; it can be understood that the intersection of the first pliers body 1 and the second pliers body 2 can also be provided with a rotation column on one pliers body and a rotation blind hole on the other pliers body, and the rotation column is inserted into the rotation blind hole to realize rotational connection.

[0027] For the above-mentioned clamping part 3, please refer to Figure 3The clamping part 3 includes a first clamping part 31, a second clamping part 32, a receiving groove 33, an abutting groove 34, an abutting platform 35 and a flexible part (not shown). The first clamping part 31 and the second clamping part 32 are symmetrically arranged about the cross position of the fastening tool 1000. The first clamping part 31 is fixed to one end of the first pliers body 1, and the second clamping part 32 is fixed to one end of the second pliers body 2. The first clamping part 31 and the second clamping part 32 are located on the same side of the first pliers body 1 and the second pliers body 2. The clamping part, i.e., the first clamping part 31 and the second clamping part 32, is also provided with a receiving groove 33 and an abutting groove 34. The abutting groove 34 is connected to the receiving groove 33, and the cross-sectional area of ​​the abutting groove 34 is different from the cross-sectional area of ​​the receiving groove 33, so as to form an abutting platform 35 between the receiving groove 33 and the abutting groove 34. The flexible part is attached to the inner walls of the receiving groove 33 and the abutting groove 34.

[0028] In the embodiment of the utility model, preferably, the cross-sectional area of ​​the abutment groove 34 is smaller than the cross-sectional area of ​​the receiving groove 33, thereby limiting the orientation of the abutment platform 35. Since the first clamping part 31 and the second clamping part 32 are symmetrically arranged about the intersection position of the fastening tool 1000, the abutment platform 35 of the first clamping part 31 and the abutment platform 35 of the second clamping part 32 are symmetrical in orientation. When the two gold-plated connectors are respectively received in the abutment groove 34 of the first clamping part 31 and the abutment groove 34 of the second clamping part 32, the two gold-plated connectors respectively abut the abutment platforms 35 of the first clamping part 31 and the second clamping part 32. By rotating the first clamp body 1 and the second clamp body 2, the first clamp body 1 and the second clamp body 2 respectively drive the first clamping part 31 and the second clamping part 32, so that the first clamping part 31 and the second clamping part 32 are close to each other, and under the action of the abutment platform 35, the two gold-plated connectors form a stable connection.

[0029] In some embodiments, the receiving groove 33 can be omitted. For example, only an abutment platform 35 is set at the outer edge of the clamping portion 3 of the fastening tool 1000, and the cable connected to the gold-plated connector is suspended in the air, leaving only the abutment groove 34, which can also achieve a fastened connection of the gold-plated connector.

[0030] The receiving groove 33 is V-shaped, and the abutment groove 34 is V-shaped. The V-shaped receiving groove 33 and the abutment groove 34 help the fastening tool 1000 to adapt to gold-plated connectors and cables of different sizes. The setting of the V-shaped groove makes the contact surface of the gold-plated connector and the cable and the fastening tool 1000 fit more closely, reducing the shaking of the gold-plated connector and the cable in the groove, thereby reducing the possible wear on the gold-plated connector and the cable.

[0031] In some embodiments, the shapes of the receiving groove 33 and the abutment groove 34 include but are not limited to U-shape, V-shape, etc., as long as it is ensured that the gold-plated connector and the cable can be respectively received in the abutment groove 34 and the receiving groove 33.

[0032] The inner walls of the receiving groove 33 and the abutting groove 34 are provided with flexible parts, and the flexible parts include but are not limited to the following materials: engineering plastics, hard rubber, etc. The provision of the flexible parts protects the cables received in the receiving groove 33 and the gold-plated connectors received in the abutting groove 34, thereby avoiding wear of the gold-plated connectors and cables due to direct contact between the fastening tool 1000 and the gold-plated connectors and cables, thereby affecting the aesthetics.

[0033] For the first clamp body 1 and the second clamp body 2, please refer to Figure 1 Combined with Figure 4 The first pliers 1 is provided with a first rotation groove 11 at the intersection of the first pliers 1 and the second pliers 2, and the second pliers 2 is provided with a second rotation groove 21 at the intersection of the first pliers 1 and the second pliers 2, wherein the first rotation groove 11 and the second rotation groove 21 are engaged with each other. A certain rotation space is reserved in the first rotation groove 11 and the second rotation groove 21, so that the first pliers 1 and the second pliers 2 rotate in the first rotation groove 11 and the second rotation groove 21 after being engaged, and the groove wall of the first rotation groove 11 and the groove wall of the second rotation groove 21, during the rotation of the first pliers 1 and the second pliers 2, respectively limit the second pliers 2 and the first pliers 1, so as to prevent the first pliers 1 and the second pliers 2 from having an opening too large during the rotation and opening, which is inconvenient for the next tightening work, or to prevent the first pliers 1 and the second pliers 2 from having an opening too small during the rotation and convergence, which causes the first clamping part 31 and the second clamping part 32 to collide, causing damage to the tightening tool 1000.

[0034] The first pliers body 1 is provided with a first blind hole 12, the second pliers body 2 is provided with a second blind hole 22, and the first blind hole 12 and the second blind hole 22 are arranged opposite to each other; one end of the elastic member 5 is received in the first blind hole 12, and the other end of the elastic member 5 is received in the second blind hole 22, and the elastic member 5 is in a slightly compressed state in the tightening tool 1000. The elastic member 5 exerts a force on the first pliers body 1 and the second pliers body 2 to make the two move away from each other. When the tightening tool 1000 is tightened by an external force, the elastic member 5 is compressed and continues to be compressed until the tightening tool 1000 completes the tightening work. At this moment, the elastic potential energy of the elastic member 5 is the maximum, the external force disappears, the elastic potential energy of the elastic member 5 is released, and the tightening tool 1000 is restored to its original state under the action of the elastic potential energy of the elastic member 5.

[0035] In some embodiments, the elastic member 5 may be a component such as a spring or a spring sheet that can store and release elastic potential energy. In some embodiments, the elastic member 5 may be omitted. After the tightening tool 1000 completes the tightening work, it is restored to its original state by manpower. The elastic member 5 may be located on either side of the left or right side of the intersection of the first pliers body 1 and the second pliers body 2. The utility model preferably arranges the elastic member 5 on the side away from the clamping portion 3.

The embodiment of the utility model can accommodate two cables with gold-plated connectors in the clamping part 3, and both cables are accommodated in the accommodating groove 33. Both gold-plated connectors are accommodated in the abutting groove 34 and abut the abutting platform 35. The rotation of the first clamp body 1 and the second clamp body 2 drives the rotation of the clamping part 3, and the elastic part 5 is compressed and contracted to accumulate elastic potential energy. The two clamping parts 3 located at one end of the first clamp body 1 and the second clamp body 2 are close to each other to achieve a fastened connection between the two gold-plated connectors. After the fastening work is completed, the compressed elastic potential energy is released, and the fastening tool 1000 returns to its original state. In addition, due to the presence of the labor-saving device 4, the user can save the physical strength required for manually plugging the gold-plated connectors when using the fastening tool 1000 to perform the fastening operation of the gold-plated connectors, thereby improving work efficiency and improving the stability of the cable connection.
