[0037] In some embodiments, see Figures 4 to 7 The clamping mechanism 100 further includes a floating joint 16 and a positioning plate 17, wherein the floating joint 16 is fixedly connected to the second clamping plate 12 via the positioning plate 17. The floating joint 16 is located between the positioning plate 17 and the fixed plate 14, and the positioning plate 17 is located between the second clamping plate 12 and the floating joint 16. The connection method between the positioning plate 17 and the second clamping plate 12 may include, but is not limited to, one or more combined connections such as welding, clamping, and gluing.

[0038] Combination Figures 5 to 7 The positioning plate 17 includes a body 171 and a protrusion 172. The protrusion 172 is fixedly connected to the side of the body 171 away from the second clamping plate 12, and the protrusion 172 protrudes relative to the body 171 along the positive direction of the X-axis. The positioning plate 17 is fixedly connected to the floating joint 16 through the cooperation of the clamping portion and the clamping groove. In this example, the protrusion 172 of the positioning plate 17 is recessed with a clamping groove 1721, and the floating joint 16 is provided with a clamping portion 160, and the clamping portion 160 is clamped in the clamping groove 1721, so that the floating joint 16 is fixedly connected to the positioning plate 17. In other examples, the protrusion 172 of the positioning plate 17 is convexly provided with a clamping portion, and the floating joint 16 is recessed with a clamping groove, and the clamping portion is clamped in the clamping groove, so that the floating joint 16 is fixedly connected to the positioning plate 17.

[0039] The floating joint 16 includes a fixed member 161 and a rotating member 163. The clamping portion 160 is disposed at one end of the fixed member 161 away from the rotating member 163. One end of the fixed member 161 facing the rotating member 163 and one end of the rotating member 163 facing the fixed member 161 are rotatably connected through the cooperation of the rotating head and the receiving groove. One end of the rotating member 163 away from the fixed member 161 is fixedly connected to the push rod 13. One end of the rotating member 163 away from the fixed member 161 is concavely provided with a connecting groove, and the push rod 13 is fixedly inserted into the connecting groove of the rotating member 163, so that the rotating member 163 and the push rod 13 are fixedly connected. The fixing member 161 further includes a rotating head 1611 which is disposed opposite to the clamping portion 160 . An end of the rotating member 163 facing the fixing member 161 is provided with a receiving groove 1631 . The rotating head 1611 is rotatably positioned in the receiving groove 1631 so that the fixing member 161 and the rotating member 163 are rotatably connected.

[0040] In this example, the inner cavity surface of the receiving groove 1631 is spherical, the outer wall surface of the rotating head 1611 is spherical, and the rotating head 1611 can rotate smoothly relative to the inner cavity surface of the receiving groove 1631. The fixing member 161 has an axis line 1613, and the fixing member 161 is symmetrical about the axis line. The outer diameter of the rotating head 1611 increases first and then decreases along the direction of the axis line 1613 and along the positive direction of the X-axis. The inner diameter of the receiving groove 1631 first decreases, then increases, and then decreases along the positive direction of the X-axis. The minimum inner diameter of the receiving groove 1631 is smaller than the maximum outer diameter of the rotating head 1611, and the rotating head 1611 is positioned in the receiving groove 1631 and is not easy to fall off from the receiving groove 1631.

[0041] In other examples, a receiving groove is recessed at one end of the fixed member 161 facing the rotating member 163, and the rotating member 163 includes a rotating head, and the rotating head 1611 is rotatably positioned in the receiving groove 1631, so that the fixed member 161 and the rotating member 163 are rotatably connected. In other examples, the inner cavity surface of the receiving groove 1631 can also be pear-shaped or oval-shaped, and the outer wall surface of the rotating head 1611 cooperates with the inner cavity surface of the receiving groove 1631 and is also pear-shaped or oval-shaped, which is not limited here.

[0042] During the circumferential rotation of the push rod 13, the rotation axis of the push rod 13 may be deflected relative to the X-axis, thereby causing the second clamping plate 12 to slide along the Y-axis, thereby causing the battery 200 to be poorly connected to the discharge circuit, thereby affecting the discharge of the battery 200. In this embodiment, the rotation axis of the push rod 13 is deflected relative to the X-axis direction, and the push rod 13 drives the rotating member 163 to rotate. The rotation axis of the rotating member 163 is deflected relative to the X-axis direction. The rotating head 1611 is rotatably engaged in the receiving groove 1631. The rotating head 1611 can compensate for the deflection of the rotation axis of the push rod 13 relative to the X-axis. The fixing member 161 pushes against the second clamping plate 12 along the negative direction of the X-axis, and then the first clamping plate 11 and the second clamping plate 12 clamp the battery 200. On the other hand, the rotating head 1611 is rotatably engaged in the receiving groove 1631, which can prevent the positioning plate 17 and the second clamping plate 12 from rotating with the push rod 13.

[0043] In some embodiments, the clamping mechanism 100 is used to fix multiple batteries 200, the first clamping plate 11 and the second clamping plate 12 are both long plates, the first clamping plate 11 and the second clamping plate 12 have a certain length along the Y-axis direction, and multiple batteries are arranged at intervals along the length direction of the first clamping plate 11 or the second clamping plate 12. In this way, the clamping mechanism 100 can clamp multiple batteries 200 at the same time, and then discharge multiple batteries 200 at the same time, which can improve the discharge efficiency.

The second conductive column 32 includes a second fixing member 321 and a second abutting member 323, which are fixedly connected and located between the battery 200 and the second fixing member 321. One end of the second fixing member 321 away from the second abutting member 323 extends out of the second clamping plate 12.

[0052] The first conductive column 31 also includes a limiting member 316. The portion of the first fixing member 311 extending out of the first clamping plate 11 is fixedly inserted into the limiting member 316. The outer diameter of the limiting member 316 is greater than the inner diameter of the first step groove 116. When the elastic member 315 can provide elastic force to the first conductive column 31, the limiting member 316 and the first clamping plate 11 abut against each other to prevent the first conductive column 31 from falling off from the first step groove 116.

[0053] When the clamping mechanism 100 clamps multiple batteries 200 at the same time, since there is a processing error in the length of the battery 200 during the production process, the first fixing member 311, the first abutment member 313 and the elastic member 315 are provided to compensate for the gap caused by the dimensional error of the battery 200 in the length direction, so that the clamping mechanism 100 can clamp multiple batteries 200 at the same time.

The multiple batteries 200 are respectively positioned in the anti-middle grooves, so that the first pole 205 of the battery 200 is opposite to the first conductive pole 31 along the X-axis direction, and the second pole 206 of the battery 200 is opposite to the second conductive pole 32 along the X-axis direction, which can avoid placement errors. The handle 15 is rotated, and the rotation of the handle 15 drives the push rod 13 to rotate. The push rod 13 is spirally transmitted relative to the fixed plate 14 along the negative direction of the X-axis. The rotation of the push rod 13 drives the rotating part 163 of the floating joint 16 to rotate. At the same time, the push rod 13 can push the rotating part 163 of the floating joint 16 to slide along the negative direction of the X-axis. The rotating part 163 of the floating joint 16 rotates relative to the fixed part 161, and the rotating part 163 of the floating joint 16 pushes the fixed part 161 to slide along the negative direction of the X-axis.
