Retaining device for combining fittings to a vehicle body

Abstract

A retaining device for combining fittings to a vehicle body comprises an L shape piece, a base, at least one thread rod, and a press plate. 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 plate rotates the extending end of the L shape piece so that the insert end is against the edge frame at an inner side of the mask. 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 pinholes at the upper surface of the base are used with a mounting seat for securing an object being used.

What is claimed is:  
     
         1 . 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;    a base firmly secured to an inner surface at a distal end of the extending end of the L shape piece; 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 the thread rod to displace;    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 plate rotates the extending end of the L shape piece so that the insert end is against the edge frame at an inner side of the mask, 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.    
     
     
         2 . The retaining device for combining fittings to a vehicle body as claimed in    claim 1   , wherein a top of the press plate with respect to a ejecting portion of the thread rod is installed with pits for avoiding that in the process of the thread rod applying force, the press plate is shifted.  
     
     
         3 . The retaining device for combining fittings to a vehicle body as claimed in    claim 1   , wherein the L shape piece and the base are formed with holes or trenches for being passed through by electric wires.  
     
     
         4 . The retaining device for combining fittings to a vehicle body as claimed in    claim 1   , wherein an inner surface of the insert end of the L shape piece is formed with coarse slide-preventing texture.  
     
     
         5 . The retaining device for combining fittings to a vehicle body as claimed in    claim 1   , wherein the base is made by plastics or bakelite.  
     
     
         6 . The retaining device for combining fittings to a vehicle body as claimed in    claim 1   , further comprising a carrying enhancing structure including a force applying seat firmly secured to a bottom of the L shape piece, a thread rod screwedly connected to a front plate of the force applying seat, and an ejecting plate being pin-connected to a front end of the thread rod; wherein by the ejecting plate to clamp a lateral wall of the clamping portion, the base can be firmly secured and has a supporting force for bearing object.  
     
     
         7 . 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.    
     
     
         8 . 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.
