Ceramic tile leveling bracket, pushing and clamping pliers and ceramic tile leveling and laying system

A ceramic tile leveling and laying system comprising:

• a ceramic tile leveling bracket, which is provided at a junction between two adjacent ceramic tiles;
• an insertion block having one end inserted into the ceramic tile leveling bracket;
• and
• pushing and clamping pliers, being configured to push the insertion block into the ceramic tile leveling bracket so that the insertion block is clamped to the ceramic tile leveling bracket;
• wherein the ceramic tile leveling bracket comprises:
• a pad for supporting bottom surfaces of the two adjacent ceramic tiles;
• an insert protruding from an upper surface of the pad, for being inserted into a gap between the two adjacent ceramic tiles;
• and
• a breakable sheet located at a lower portion of the insert and adjacent to the pad;
• wherein the insert comprises:
• a hole which penetrates the insert and into which the insertion block is inserted;
• a bayonet disposed on a side edge of the insert on one or either side, and the bayonet having a height from the pad which is greater than a height of the sheet from the pad;
• wherein the bayonet is configured to be engaged by a withdraw tool to remove an upper part of the insert;
• and
• a hook-shaped engagement block disposed on a side edge of the insert on one or either side and the hook-shaped engagement block protruding toward the bayonet;
• wherein a bottom of the bayonet is arc-shaped, and a portion of the bayonet that is close to the hook-shaped engagement block forms a hook-shaped bayonet portion;
• wherein the pushing and clamping pliers comprises:
• a first component, comprising a first clamping portion and a first handheld portion;
• a second component, comprising a second clamping portion and a second handheld portion;
• and
• a pivot via which the second clamping portion that is rotatably connected to the first clamping portion;
• characterized by further comprising:
• a first clamping block disposed at a top end of the first clamping portion,
• a second clamping block disposed at a top end of the second clamping portion and arranged opposite the first clamping block;
• a clamping groove recessed from an inner side wall of the first clamping block, with a direction of an opening of the groove facing the second clamping block;
• and
• a clamping-through groove penetrating through the second clamping block and disposed opposite the clamping groove;
• wherein the clamping-through groove is aligned with the clamping groove in an opening and closing direction of the pushing and clamping pliers when the pushing and clamping pliers are closed.
