[0013] As a further description of the above technical solution:

[0014] The bottom end of the U-shaped plate is vertically fixedly connected with a mounting rod, and the mounting rod is installed inside the mounting hole.

[0015] By adopting the above technical solution, the horizontal movement of the U-shaped plate is limited by the mutual cooperation between the mounting rod and the mounting hole.

[0022] By means of the above technical solution, the new soft-pack lithium battery of the utility model has at least the following beneficial effects:

[0023] 1. Compared with the prior art, the novel soft-pack lithium battery has a connecting component. When connected, the connecting wire is inserted into the inside of the connecting cylinder so that the conductive column fits with the pole ear. Then, the knob is turned to drive the two-way screw rod to rotate. The two-way screw rod makes the two L-shaped rods move closer to each other under the action of the loose hole, so that the two L-shaped rods drive the two arc-shaped clamping plates to clamp and fix the outer wall of the connecting wire. When the connecting wire and the lithium battery body rotate, the connecting wire will drive the ring to rotate inside the T-shaped ring groove through the connecting cylinder, which will not cause the twisting of the connecting wire. In this process, the conductive column is always in contact with the pole ear, which does not affect the use of the soft-pack lithium battery. When sharing, just turn the knob in the opposite direction. Compared with the existing soft-pack lithium battery, the connecting wire and the soft-pack lithium battery may rotate during use. Since the above-mentioned pole ear and the connecting wire are fixedly connected, the connecting wire and the soft-pack lithium battery cannot rotate, which causes the connecting wire to be twisted. The connecting wire is easily damaged in the twisted state for a long time, which reduces the service life. The soft-pack lithium battery can ensure that the connecting pole ear and the connecting wire are tightly connected. At the same time, the connecting pole ear and the connecting wire can be rotated at will without separation, avoiding the connection wire being in a twisted state due to the rotation of the connecting wire and the soft-pack lithium battery, thereby damaging the connecting wire and improving the service life.

[0024] 2. Compared with the prior art, this new soft-pack lithium battery, through the provided locking component, when disassembling the U-shaped plate, pulls the pull rod to move horizontally, so that the pull rod drives the end of the limit rod to move out from the inside of the limit hole, that is, the limit on the vertical movement of the U-shaped plate is released. In this process, the baffle and the second L-shaped plate will squeeze the spring, and then drive the mounting rod to move vertically upward through the U-shaped plate, so that the mounting rod is moved out from the inside of the mounting hole, that is, the disassembly of the U-shaped plate is completed. The soft-pack lithium battery can fix the connecting component on the outer wall of the lithium battery body, and can quickly disassemble the connecting component for easy reuse.

When the connecting wire 211 and the lithium battery body 100 rotate, the connecting wire 211 will drive the ring 204 to rotate inside the T-shaped ring groove 203 through the connecting tube 205, and will not cause the twisting of the connecting wire 211. In this process, the conductive column 212 is always in contact with the pole ear 120, which does not affect the use of the soft-pack lithium battery. When disassembling, just turn the knob 213 in the opposite direction.

[0036] The locking component 300 can fix the connecting component 200 on the outer wall of the lithium battery body 100, and can quickly disassemble the connecting component 200 for easy reuse.
