Easily adjusted skate

A skate comprising a front seat, a rear seat and a buckle and a lower cover for connecting the front seat and the rear seat;

• wherein
• the buckle is installed in the lower cover and tightly fixed to a predetermined position of the front seat, the buckle is fixed to an upper side of the lower cover by a stud, a tooth bank is integrally formed to a bottom of the rear seat and engaged to a lateral side of the buckle;
• an upper side of the lower cover has a confining seat;
• the confining seat has guide grooves at two sides thereof;
• a locking shaft seat is formed between the two guide grooves;
• and
• the buckle has a stepped elliptical hole at a predetermined position thereof;
• the elliptical hole is aligned with the locking shaft seat of the lower cover so that the locking shaft seat is within the elliptical hole;
• thereby, the buckle slides along the linear guide grooves of the lower cover;
• one lateral side of the buckle has engaging teeth which protrude downward and extend inward so that the engaging teeth are engaged with the tooth bank at a lower end of the front seat;
• one end of the buckle which passes through the lower cover has a receiving hole;
• a spring is positioned in the receiving hole;
• an outer end of the spring is in contact with the front seat;
• wherein the buckle is capable of being pressed by a user from a lateral side;
• the buckle will compress the spring so that the engaging teeth of the buckle separates from the tooth bank;
• and thus the size of the skate is capable of being adjusted.
