When the bracket is installed, the connecting plate 112 is inserted into the base 101, and the control screw 106 is rotated to push the control block 108 into the bottom of the connecting rod 104, so that the connecting tube 103 and the connecting rod 104 are ejected, and at the same time, the fixing block 105 is pushed into the limiting groove 116, so that the connecting plate 112 is fixed. The fixing block 105 is fixed to prevent the connecting plate 112 from being disengaged. When the connecting plate 112 needs to be disassembled, the control screw 106 is rotated to release the control block 108 on the connecting rod 104, and the connecting cylinder 103 and the connecting rod 104 are reset through the torsion spring in the connecting cylinder 103. At the same time, the fixing block 105 is brought out of the limiting groove 116, and the control of the fixing block 105 on the connecting plate 112 is released, so that the connecting plate 112 can be easily removed from the base 101.

When the connecting plate 112 needs to be disassembled, the control screw 106 is rotated to release the control block 108 from controlling the connecting rod 104. The connecting cylinder 103 and the connecting rod 104 are reset through the torsion spring in the connecting cylinder 103. At the same time, the fixing block 105 is brought out of the limiting groove 116 to release the control of the fixing block 105 on the connecting plate 112, so that the connecting plate 112 can be easily removed from the base 101. This solves the problem that the multi-functional rear seat bracket of the electric vehicle is fixed to the support frame by the locating pin. The locating pin is easily detached during use, which makes the support frame fall off easily and causes the takeaway box to fall off.
