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

Pushing and clamping pliers used to push an insertion block into a ceramic tile leveling bracket, the pushing and clamping pliers comprising:

• 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;
• a pivot via which the second clamping portion is rotatably connected to the first clamping portion;
• a first clamping block disposed at a top end of the first clamping portion, away from the first handheld portion;
• a second clamping block disposed at a top end of the second clamping portion, away from the second handheld portion;
• a first groove inwardly recessed from an inner side wall of the first clamping block, with a direction of opening of the clamping groove facing the second clamping portion;
• and
• a second groove, which penetrates the second clamping block toward the first clamping block and is disposed opposite the first groove;
• the first groove and the second groove being configured to hold the insertion block when the pushing and clamping pliers push the insertion block into the ceramic tile leveling bracket;
• wherein the first clamping portion extends and bends from the first handheld portion, the second clamping portion extends and bends from the second handheld portion, and the first clamping portion and the second clamping portion bend in the same direction;
• wherein the pushing and clamping pliers further comprises an elastic member one end of the elastic member connected to the first component and another end of the elastic member connected to the second component, the elastic member configured to exert an elastic force to cause the first component and the second component to move in an opening direction;
• wherein the pushing and clamping pliers further comprise a locking device configured to overcome the elastic force of the clastic member when the locking device is locked, so that the first component and the second component are in a closed state;
• wherein the pushing and clamping pliers further comprise a first bent portion, which is part of the first clamping portion and is sheathed outside the pivot;
• and
• a second bent portion, which is part of the second clamping portion and is sheathed outside the pivot;
• the locking device comprises:
• a locking slot disposed on the first clamping portion and located away from an outer side wall of the first bent portion of the first clamping portion;
• a locking member rotatably connected to the second clamping portion and disposed opposite the locking slot;
• and
• a blocking block disposed on the first clamping portion and disposed opposite the second bent portion of the second clamping portion, the blocking block being configured such that when the pushing and clamping pliers have a maxi am opening angle, the blocking block comes into contact with the second bent portion of the second clamping portion.
