         2 . The apparatus according to  claim 1 , further comprising a handle at an end of the second end portion of the support unit. 
     
     
         3 . The apparatus according to  claim 1 , further comprising a trigger unit coupled to the anchor deploying unit, and configured to trigger the anchor deploying unit to deploy the anchor by using an elastic force or an air pressure. 
     
     
         4 . The apparatus according to  claim 1 , further comprising a support-unit detaching unit configured, when the second blocking unit moves toward the anchor by a predetermined distance along the support unit, to detach a portion of the support unit protruded from the second blocking unit. 
     
     
         5 . The apparatus according to  claim 1 , wherein the first unidirectional sawtooth portion and the second unidirectional sawtooth portion are configured, when coupled to the first coupling portion and the second coupling portion, respectively, to allow the first coupling portion and the second coupling portion to move toward the anchor and keep the first coupling portion and the second coupling portion from moving in an opposite direction, respectively. 
     
     
         6 . The apparatus according to  claim 5 , further comprising:
 a first coupling release unit configured to release coupling of the first unidirectional sawtooth portion and the first coupling portion to allow the first coupling portion to move in the opposite direction; and   a second coupling release unit configured to release coupling of the second unidirectional sawtooth portion and the second coupling portion to allow the second coupling portion to move in the opposite direction.   
     
     
         7 . The apparatus according to  claim 1 , wherein
 the second blocking unit includes a first plate having a predetermined width toward the anchor and a second plate attached to the first plate on an opposite side of the anchor,   the first plate is formed in a pad shape having elasticity, and   the second plate is formed of a material having rigidity stronger than the first plate.   
     
     
         8 . The apparatus according to  claim 7 , wherein
 the first plate is formed of at least one of silicone, rubber, fabric, and gel pack, and   the second plate is formed of at least one of metal, plastic, reinforced plastic, resin, and rubber.   
     
     
         9 . The apparatus according to  claim 7 , wherein the second plate is formed of a lid having a diameter larger than an outer circumference of the first plate and surrounds a part of the first plate in a width direction. 
     
     
         10 . The apparatus according to  claim 1 , wherein the anchor includes
 a cap inserted into the first end portion of the support unit,   a plurality of upper ribs each formed in a rod shape including a first portion and a second portion, wherein the first portion is rotatably fixed to the cap,   a first wing fixed to a first side of each of the plurality of upper ribs,   a second wing fixed to a second side of each of the plurality of upper ribs, and   a plurality of support ribs each formed in a rod shape including a first portion and a second portion, wherein the first portion of each of the plurality of support ribs is rotatably fixed to the second portion of each of the plurality of upper ribs, and the second portion of each of the plurality of support ribs is rotatably fixed to the anchor deploying unit.   
     
     
         11 . The apparatus according to  claim 10 , wherein
 a width of the first wing is narrower than a width of the second wing, and   when the anchor is deployed, the first wing is positioned on an inner side of the second wing such that the first wing supports the second wing.   
     
     
         12 . The apparatus according to  claim 11 , wherein
 the first wing is formed of a rigid material, and   the second wing is formed of an elastic material.
