Retaining device for combining fittings to a vehicle body

A retaining device for combining fittings to a vehicle body, comprising:

• an L shape piece having an insert end and a extending end which are bending through 90 degrees;
• coarse slide-preventing texture being formed on an inner surface of the insert end, and a lateral side at a distal end of the extending end having an ear bending inwards through 90 degrees and pin holes being installed with pin holes;
• a base firmly secured to a distal end of the extending end of the L shape piece by hinges;
• and a lateral surface of the base being installed with at least one penetrating stud hole and an upper surface of the base being installed with a plurality of thread holes or pin holes;
• at least one thread rods exactly screwedly installed in the penetrating stud hole at the lateral surface of the base;
• and
• a press plate being installed at a front end of the thread rod and is driven to displace;
• and
• a set of pin rods locking to the pin holes of the ear or on the lateral surface of the base;
• wherein by the insert end of the L shape piece being inserted into a gap at an edge frame of a mask in a car, the pin rods lock the base to the inner surface of the distal end of extending end of the L shape piece;
• and then the thread rod drives the press plate to move forwards until the insert end of the L shape piece and the press plate tightly clamps the edge frame of the mask so that the base is steadily positioned;
• the thread holes or pin holes at the upper surface of the base is used with a mounting seat for securing an object being used.

A retaining device for combining fittings to a vehicle body, comprising:

• an L shape piece having an insert end and a extending end which are bending through 90 degrees;
• coarse slide-preventing texture being formed on an inner surface of the insert end, and a plurality of threaded trenches with each articulated distance are installed at the center of the distal end of the extending end of the L shape piece;
• a spiral rod having a spiral texture with an articulated distance identical to that the threaded trench;
• and
• a base moving longitudinally freely to be engaged to the extending end of the L shape piece;
• a center at the bottom of the base being installed with a concave chamber which exactly encloses the spiral rod;
• wherein by the insert end of the L shape piece being inserted into a gap at an edge frame of a mask in a car, the spiral rod is rotated to drive the base to move forwards;
• and then the thread rod drives the press plate to move forwards until the insert end of the L shape piece and the press plate tightly clamps the edge frame of the mask so that the base is steadily positioned;
• the thread holes or pin holes at the upper surface of the base is used with a mounting seat for securing an object being used.
