Pop-up mechanism having a button and sliding pillars

An electrical charger for charging an electronic device, the electrical charger comprising:

• a base;
• a connector exposed out of the base for connecting the electronic device;
• and
• a pop-up mechanism received in the base and comprising:
• a plurality of pushing pillars slidably set beside the connector, a top end of each pushing pillar extending out of the base;
• and
• a button set on the base;
• wherein the button drives the pushing pillars to slide upwards and push the electronic device away from the connector when the button is pressed.

A pop-up mechanism comprising:

• a base board;
• a restricting unit connected to and substantially parallel to the base board, the restricting unit comprising a vertical locking sidewall and a bottom sidewall connecting the locking sidewall, the locking sidewall defining a locking cutout therein;
• a pushing pillar slidably received in the restricting unit and resiliently connected to the bottom sidewall of the restricting unit via a first spring, the pushing pillar defining a locking groove corresponding to the locking cutout of the locking sidewall;
• a transmission piece rotatably connected to the locking sidewall and comprising a locking arm and an engaging arm coupled to the locking arm, the locking arm comprising a locking protrusion aligned with the locking cutout of the locking sidewall;
• and
• a button slidable relative to the base board, the button positioned above the engaging arm for pressing the engaging arm down;
• wherein when the pushing pillar is slid to a position where the locking groove aligns with the locking cutout, the transmission piece automatically rotates and the locking protrusion inserts into the locking groove via the locking cutout thereby restricting the pushing pillar from sliding;
• and
• when the button is pressed and presses the engaging arm down, the transmission piece rotates and moves the locking protrusion of the locking arm out of the locking groove, whereupon the pushing pillar is pushed to slide up in the restricting unit by restoring force of the first spring.
