When the two vertical rods 31 are released, the two torsion springs recover and respectively drive the two rotating rods 21 to rotate in the opposite direction, and the two rotating rods 21 respectively drive the two arcs to rotate in a relatively close direction, and at the same time, the two second springs 27 recover and respectively drive the two third curved plates 22 to rotate in a relatively close direction through the two short rods 26.

[0059] Working principle: When the photovoltaic mobile power supply body needs to be moved, first, manually move the two vertical rods 31, the two vertical rods 31 respectively drive the two third arc plates 22 to move, the two third arc plates 22 respectively drive the two rotating rods 21 to rotate, the two rotating rods 21 respectively push the two torsion springs to compress, the two third arc plates 22 respectively drive the two short rods 26 to move, and the two second springs 27 are respectively stretched by the two short rods 26. Then, the photovoltaic mobile power supply body is placed horizontally between the two third arc plates 22 and the support plate 3, the two vertical rods 31 are released, the two torsion springs are restored and respectively drive the two rotating rods 21 to rotate in the opposite direction, the two rotating rods 21 respectively drive the two arcs to rotate in a relatively close direction, and at the same time, the two second springs 27 are restored and respectively drive the two third arc plates 22 to rotate in a relatively close direction through the two short rods 26, until the two third arc plates 22 contact the photovoltaic mobile power supply body and the torsion of the two torsion springs is used to clamp the photovoltaic mobile power supply body. When the mobile base is pushed to move, if the road surface is uneven, the mobile base vibrates up and down, and the photovoltaic mobile power source body vibrates up and down due to inertia, the support plate 3 slides in the four first slide grooves, the support plate 3 drives the sleeve 4 to move vertically, the sleeve 4 drives the first rotating shaft 5 to rotate through the first thread and the second thread, the first rotating shaft 5 drives the four elastic sheets 8 to deviate, and the elastic sheets 8 absorb the inertial force generated by the photovoltaic mobile power source body, the support plate 3 and the clamping device.

When the mobile base stops moving, manually rotate the first turntable 23, the first turntable 23 drives the threaded rod 25 to rotate, the threaded block applies a reverse force to the threaded rod 25, the threaded rod 25 moves downward until it contacts the ground, and the friction between the threaded rod 25 and the ground fixes the mobile base to prevent the mobile base from sliding. When the mobile base needs to be moved, the turntable is rotated in the opposite direction, the turntable drives the threaded rod 25 to rotate in the opposite direction, the threaded rod 25 moves upward and disengages from the ground, and the fixation of the mobile base is released. When adjusting the angle of the photovoltaic mobile power supply body, pull the lever 20 upward, the lever 20 pushes the first spring 18 to compress, the lever 20 drives the second arc strip 17 and several second teeth to move upward, and several second teeth are disengaged from the first arc strip 16 and several first teeth. At this time, the second arc plate 11 can be moved to adjust the angle of the photovoltaic mobile power supply body.When the photovoltaic mobile power source body is at a suitable angle, the lever 20 is released, the first spring 18 recovers and drives the lever 20 to move downward, the lever 20 drives the second arc strip 17 and the plurality of second teeth to move downward, and the plurality of second teeth mesh with the plurality of first teeth. At this time, due to the support force of the first arc strip 16, the second arc strip 17, the plurality of first teeth, the plurality of second teeth, the lever 20, the first spring 18, the second limit block 19, and the limit hole, the second arc plate 11 is fixed, and the external force can no longer change the angle of the photovoltaic mobile power source body.
