One end of the first spring 1031 is connected to the bottom surface of the mounting groove 1011, and the other end is connected to the bottom of the first wedge block 1022 and the second wedge block 1023; one end of the second spring 1032 is connected to the first side S1 of the mounting groove 1011, and the other end is connected to the second inclined surface (S4) of the first wedge block 1022 and the second wedge block 1023.

[0075] The first spring 1031 or the second spring 1032 can be arranged on the base 101 through a blind hole, or other arrangements can be used, and the application is not limited thereto.

Under the joint driving of the first spring 1031 and the second spring 1032, the first wedge block 1022 and the second wedge block 1023 move along the first side S1 of the mounting groove 1011, respectively, so that the first inclined surface S3 of the first wedge block 1022 and the second wedge block 1023 and the second side S2 of the clamping block 1021 are in a state of adhesion or separation.

[0077] In the application, the first spring 1031 and the second spring 1032 can be one or more, or other elastic components, and the application is not limited thereto.

[0078] The second driving unit 104 comprises a driver 1041, a connecting plate 1042, and a connecting rod 1043.

Thus, the power of the driver 1041 is transmitted to the clamping block 1021 through the output shaft 10411, the connecting plate 1042, and the connecting rod 1043, so that the second driving unit 104 can drive the clamping block 1021 to move upward or downward along the first direction D1. The distance of the clamping block 1021 moving upward or downward is 0.5mm-1mm. Of course, according to the structure and size of the electrode sheet 10, the moving distance can also be set accordingly, and the present application is not limited thereto.

[0079] The connecting rod 1043 in the present application can be composed of a limiting stud 10431 and a limiting bolt 10432, the limiting stud 10431 is sleeved in the middle of the limiting bolt 10432, and other connecting rods can also be used, and the present application is not limited thereto.

[0080] The limiting stud 10431 is arranged in the first hole 1012 in the base 101, the clamping block 1021 is provided with a second hole 1029, the second hole 1029 is communicated with the first hole 1012, and the limiting bolt 10432 is arranged in the second hole 1029. The limiting stud 10431 can move up and down along the first direction D1 in the first hole 1012, and the limiting bolt 10432 is fixedly connected with the clamping block 1021. When the driver 1041 outputs upward power, the output shaft 10411 drives the connecting plate 1042, the limiting stud 10431, the limiting bolt 10432, and the clamping block 1021 to move upward, and when the driver 1041 outputs downward power, the output shaft 10411 drives the connecting plate 1042, the limiting stud 10431, the limiting bolt 10432, and the clamping block 1021 to move downward.

[0081] In the initial state, the first wedge block 1022, the second wedge block 1023, and the clamping block 1021 are collectively accommodated in the bottom end of the mounting groove 1011, the first wedge block 1022, the second wedge block 1023, and the clamping block 1021 are in a mutually adhering state, the connecting body 1027 is embedded in the groove 1028, at this time the first wedge block 1022 and the second wedge block 1023 press down the first spring 1031 to deform, and the first spring 1031 is in a compressed state.

[0082] To install the electrode sheet 10, the driver 1041 drives the clamping block 1021 to move upward along the first direction D1, the first spring 1031 stretches upward, the first wedge block 1022 and the second wedge block 1023 move upward along the first direction D1 under the drive of the first spring 1031, and the first wedge block 1022 and the second wedge block 1023 move away from the clamping block 1021 along the second direction D2 under the drive of the second spring 1032.

When the clamping unit 102 is in the open state, the electrode sheet 10 can be installed in the accommodation groove 1025 of the first wedge block 1022 or the second wedge block 1023.

[0084] Then, after the electrode sheet 10 is installed in the clamping unit 102, the driver 1041 drives the clamping block 1021 to move downward along the first direction D1, the first spring 1031 is compressed under force, the first wedge block 1022 and the second wedge block 1023 move downward along the first direction D1 under the pressure of the push rod 105, and the first wedge block 1022 and the second wedge block 1023 move toward the clamping block 1021 along the second direction D2 under the drive of the second spring 1032. Thus, the clamping unit 102 is in the closed state, and the electrode sheet 10 is clamped in the clamping unit 102 by the abutting portion of the clamping block 1021 abutting against the electrode sheet 10 in the accommodation groove 1025 of the first wedge block 1022 or the second wedge block 1023.
