At this time, the clamping assembly 51 first uses the first clamping jaw and the second clamping jaw to cooperate to clamp the charging head on the positioning device 2, and uses the first limiting groove and the second limiting groove to limit the moving strokes of the first clamping jaw and the second clamping jaw so as to clamp the charging head. After clamping, the trigger switch 22 controls the fourth power member to make the fourth power member provide power for the third transmission member and drive the clamping assembly 51 mounted on the fourth mounting plate 422 and the charging head clamped by the clamping assembly 51 to move. When moving to cooperate with the second guiding member, the clamping assembly 51 is rotated to facilitate conveying the charging head to the blanking area to be lowered.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
