The triangular clipping plates 51 no longer limit the movable block 43. The user can move the power supply body 4. The movement of the power supply body 4 drives the adjustment plate 41 to move. The movement of the adjustment plate 41 drives the movable block 43 to slide in the circular plate 3. After the power supply body 4 is moved to the appropriate position, the user can rotate the threaded rod 54 again to drive the triangular clipping plates 51 on the pull plate 5 to insert into the first rectangular groove 31 and the second rectangular groove 44 to limit the position.

[0027] A moving block 52 is fixedly installed on the upper end of the pull plate 5, and a second threaded groove 53 is opened through the side end of the moving block 52.
