The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0035] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0036] The present utility model provides a battery clip that is conducive to clamping, including a pair of clamping ends 1 that are hinged to each other. At least one first clamping section 11 for preventing the conductive line from detaching is provided at the front end of the clamping end 1. Second clamping sections 12 for clamping the conductive line are respectively provided on both sides of the first clamping section 11. The first clamping section 11 and any one of the second clamping sections 12 are arranged at an angle of 60° - 130°, and the first clamping section 11 protrudes from the second clamping section 12.
[0037] Please refer to Figures 1 to 2 , in this embodiment, in the technical solution provided by the present utility model, the angle setting of 60° - 130° between the first clamping section 11 and the second clamping section 12 and the protruding part of the first clamping section 11 relative to the second clamping section 12 together constitute a stable clamping space. When the conductive line shakes and collides with the first clamping section 11 and the second clamping section 12 at different angles, the resistance for the conductive line to slide towards both ends of the clamping end 1 is increased. At the same time, the protruding first clamping section 11 blocks the path for the conductive line to slide out from the front end of the clamping end 1, so that while the battery contact is clamped, it can be effectively locked in the clamping area. Even in the face of external force impacts at different large angles or long-term use wear, a stable connection state can be maintained, greatly reducing the risk that the conductive line of the battery electrode detaches from the clamping end 1 of the battery clip due to the shaking of the conductive line.
[0038] Please refer to Figure 2 , in this embodiment, one first clamping section 11 is provided at the front end of the clamping end 1, and the second clamping sections 12 on both sides are respectively arranged at 90° with respect to the first clamping section 11. When the first clamping section 11 and the second clamping sections 12 on both sides are respectively arranged at 90°, a better balance state is achieved, which not only ensures the stability of clamping but also facilitates operation and adjustment.
[0039] Please refer toFigure 2 , in this embodiment, the second clamping section 12 is provided with wavy first clamping sawteeth 121. Compared with a planar design, the wavy design has a larger contact area, which means better current transmission ability and lower resistance. Moreover, the wavy clamping sawteeth can more effectively disperse the clamping force and avoid excessive pressure at a single point. The wavy shape also forms multiple biting points between the clamping section and the conductive circuit. These biting points not only increase the friction force but also make the clamping more firm and stable.
[0040] Please refer to Figure 2 , in this embodiment, the first clamping section 11 is provided with a plurality of limiting sawteeth 111, and the limiting sawteeth 111 provided at two different clamping ends 1 are correspondingly meshed. The corresponding meshing of the limiting sawteeth 111 forms a stable locking mechanism. When the two clamping ends 1 are closed and bite with each other, the limiting sawteeth 111 will interleave with each other, forming an effect similar to gear meshing. This design enables the clamping ends 1 to support each other when subjected to an external force and resist the tendency of the conductive circuit to slip off from the front end of the clamping ends 1, thereby maintaining a firm clamping of the conductive circuit.
[0041] Please refer to Figure 2 , in this embodiment, the radius of curvature of the working surface of the first clamping sawteeth 121 is greater than the radius of curvature of the limiting sawteeth 111. By differentiating the radii of curvature of the first clamping sawteeth 121 and the limiting sawteeth 111 and combining their respective functions, the battery clamp can achieve effective clamping on the premise of ensuring the safety of the conductive circuit. The first clamping sawteeth 121 are responsible for providing a smooth clamping surface and dispersing the clamping force, while the limiting sawteeth 111 are responsible for enhancing the stability of the clamping and preventing the conductive circuit from falling off.
[0042] Please refer to Figure 1 , Figure 2 and Figure 8 , in this embodiment, the battery clamp that is conducive to clamping further includes a first clamp 2. The first clamp 2 is arranged on the end face of the clamping end 1. A plurality of second clamping sawteeth 21 having the same contour as the first clamping sawteeth 121 are respectively provided on both sides of the first clamp 2. The second clamping sawteeth 21 and the first clamping sawteeth 121 coincide in the direction perpendicular to the second clamping section 12. The setting of the first clamp 2 and the second clamping sawteeth 21 on both sides thereof significantly increases the contact area of the clamping end 1 when clamping the conductive circuit. This increased contact area not only helps to disperse the clamping force and reduce the pressure on the local area of the conductive circuit but also improves the stability and efficiency of current transmission.
[0043] Please refer to Figure 1 , Figure 2 and Figure 9, in this embodiment, the battery clip facilitating clamping further includes a second clip holder 4. The second clip holder 4 is disposed on the end face of the clamping end 1 facing the second clamping section 12. On the surface of the second clip holder 4 facing the first clip holder 2, a plurality of third clamping sawteeth 41 having the same profile as the first clamping sawteeth 121 are arranged in an array. The third clamping sawteeth 41 and the first clamping sawteeth 121 coincide in the direction perpendicular to the second clamping section 12.
[0044] Please refer to Figure 1 , Figure 2 and Figure 9 , in this embodiment, a fourth clamping sawtooth 42 is provided at the rear end of all the third clamping sawteeth 41. The radius of curvature of the acting surface of the fourth clamping sawtooth 42 is greater than the radius of curvature of the acting surface of the third clamping sawtooth 41. This design enables that during the clamping process, the conductive line is first preliminarily clamped by the third clamping sawteeth 41, and then further fixed by the fourth clamping sawteeth 42 in a more gentle manner. This differential clamping method helps to disperse the clamping force and reduce local stress concentration, thereby avoiding damage to the conductive line due to excessive clamping force.
[0045] Please refer to Figure 1 , Figure 2 and Figure 9 , in this embodiment, a fastening member 43 is provided at the front end of the second clip holder 4, and a fixing hole 112 corresponding to the protruding portion is provided on the first clamping section 11. The fastening member 43 is embedded in the fixing hole 112. The structures of the fastening member 43 and the fixing hole 112 effectively limit the movement range of the second clip holder 4 during the clamping process, thus avoiding the situation that the second clip holder 4 tilts or falls off due to the force generated during the battery clamping.
[0046] Please refer to Figure 1 , Figure 2 and Figure 9 , in this embodiment, an L-shaped elastic member 44 is connected to the rear end of the second clip holder 4. The L-shaped elastic member 44 includes a first end face 441 and a second end face 442 that are perpendicularly connected. The first end face 441 is connected to the rear end of the second clip holder 4, and the second end face 442 is installed on the end face of the clamping end 1. The L-shaped elastic member 44 causes a certain height difference between the second clip holder 4 and the clamping end 1, making it have a certain elastic effect. In addition to ensuring that the conductive line can be clamped in the clamping area, it can also reduce the wear or other force effects on the conductive line during the clamping of the battery clip, and prevent the conductive line from being cut off.
[0047] Please refer to Figures 4 to 7 , in this embodiment, the battery clip facilitating clamping further includes a clip sleeve 3 sleeved on the clamping end 1. The clip sleeve 3 is recessed with a receiving groove 31 for installing the clamping end 1, and at least one first fixing column 311 penetrating the end face of the clamping end 1 is provided in the receiving groove 31.
[0048] Please refer to Figures 4 to 7, in this embodiment, two first fixing columns 311 are provided in the receiving groove 31. The first fixing columns 311 sequentially penetrate through the end face of the clamping end 1 and the first clamping frame 2. During the clamping process, especially when facing conductive lines of different diameters or shapes, this design can ensure the relative position between the clamping end 1 and the first clamping frame 2 remains stable, avoiding loosening or displacement due to external forces.
[0049] Please refer to Figures 4 to 7 , in this embodiment, a second fixing column 312 penetrating through the clamping end 1 is provided in the receiving groove 31. The first fixing column 311 is located on one side of the second fixing column 312, and the second end face 442 is threadedly connected to the second fixing column 312. The L-shaped elastic member 44 is fixed by the second fixing column 312, which not only maintains its elasticity during the clamping process but also avoids failure due to excessive deformation. At the same time, the presence of the first fixing column 311 restricts the movement of the L-shaped elastic member 44 in a specific direction, ensuring the stability of the clamping structure.
[0050] Please refer to Figures 4 to 7 , in this embodiment, a third fixing column 313 penetrating through the clamping end 1 is provided in the receiving groove 31. The third fixing column 313 is located between the fastening member 43 and the second end face 442. The introduction of the third fixing column 313 adds a new support point to the clamping structure, especially between the fastening member 43 and the L-shaped elastic member 44. This layout helps to disperse the stress and impact force generated during the clamping process, reduce the deformation and wear of the components, and thus enhance the stability of the entire clamping structure.

[0052] The present utility model also provides a mobile power source, including a battery pack, a pair of conductive leads, and a battery clip that is conducive to clamping. The battery pack is connected to the conductive leads, and the conductive leads are connected to the clamping end 1.
