Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application claims the benefit of Chinese Patent Application No. 202120067487.0 filed on Jan. 11, 2021, the contents of which are incorporated herein by reference in their entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to support, in particular to clamp-type fitting seats and holders. 
     BACKGROUND OF THE INVENTION 
     Mobile phones and tablets may be main recreational tools when people ride in vehicles. However, holding a mobile phone or tablet with a hand may make people get tired very easily; further, the hand holding the mobile phone or tablet may be restricted to move freely. 
     A fitting seat has been designed to free hands. Two connecting rods of a backrest in a vehicle may be clamped with the fitting seat connecting with a mounting base used for fixing a mobile phone or tablet. However, the existing fitting seat is complicated in structure and poor in stability, leading to unstable clamping for the phone or tablet. 
     SUMMARY OF THE INVENTION 
     In view of this, a clamp-type fitting seat and a holder which are of simple structure and stable may be provided in the present disclosure. 
     According to one aspect of the present disclosure, there is provided a fitting seat, which may include an interconnecting piece and a coupling head arranged on the interconnecting piece. Two ends of the interconnecting piece may be bent toward each other to form first clamping parts. Each of the first clamping parts may have a first bending portion and a second bending portion which are bent in opposite direction. One end of the first bending portion may be connected to the interconnecting piece and the other end may be connected to the second bending portion. 
     According to another aspect of the present disclosure, a holder is provided, which includes the above-mentioned fitting seat and a mounting base, and the coupling head is connected to the mounting base. 
     A beneficial effect of the present disclosure is that, by means of bending two ends of the interconnecting piece toward each other to form first clamping parts each having two bending portions (i.e. first bending portions and second bending portions) with opposite bending directions, when the fitting seat is clamped to two connecting rods, the two second bending portions are abutted and pressed against the two connecting rods so that the fitting seat is able to clamp the connecting rods; meanwhile, the first bending portions may increase the deformability of the fitting seat, making the first clamping parts difficult to break and resulting in good stability; in this way, the two ends of the fitting seat are bent to form two bending parts to clamp the two connecting rods, resulting in a simple structure of the fitting seat.

     DETAILED DESCRIPTION 
     It shall be appreciated that the terms used herein and the specific structure and features disclosed are only for describing specific embodiments and are representative. However, the present disclosure can be implemented in many alternative forms and shall not be construed as being limited only to the embodiments set forth here. 
     In addition, unless otherwise clearly specified and limited, the terms “fitting”, “connecting” and “coupling” shall be understood in a broad sense, for example, connecting fixedly, detachably or integrally; or connecting in a mechanical or electrical manner; or connecting directly or indirectly via an intermediary; or internally connecting between two components. For those skilled in the art, the specific meaning of the above-mentioned terms in the present disclosure may be understood according to specific circumstances. 
     The present disclosure will be further described below with reference to  FIGS. 1 to 3  and optional embodiments. 
     As shown in  FIG. 1  and  FIG. 3 , a clamp-type fitting seat provided in an embodiment of the present disclosure may include an interconnecting piece  10  and a coupling head  11  arranged on the interconnecting piece  10 . Two ends of the interconnecting piece  10  are bent toward each other to form first clamping parts  101 . The first clamping parts  101  each have two bending portions, first bending portions  101   a  and second bending portions  101   b,  with opposite bending directions. One end of each first bending portion  101   a  is connected to the interconnecting piece  10 , and the other end is connected to the second bending portion  101   b.    
     When the fitting seat  1  is clamped to two connecting rods  3  of a backrest, the two second bending portions  101   b  are abutted and pressed against the two connecting rods  3  so that the fitting seat  1  is able to clamp the connecting rods  3 ; meanwhile, the first bending portions  101   a  may increase the deformability of the fitting seat  1 , making the first clamping parts  101  difficult to break and resulting in good stability. The two ends of the fitting seat  1  are bent to form two bending parts to clamp the two connecting rods  3 ; in this respect, the fitting seat  1  is simple in structure. 
     Furthermore, the interconnecting piece  10  and the coupling head  11  are integrally arranged without loose fixation; in this respect, no displacement between the interconnecting piece  10  and the coupling head  11  occurs and no wobble happen in a mounting base  2 , thereby improving the stability of the fitting seat  1 . 
     Specifically, the first clamping part  101  and the second clamping part  103  each are in an “S” shape, but the bending directions of the first clamping part  101  and the second clamping part  103  are different. In this embodiment, a third bending portion  102  is in a “∩” shape so as to widen the opening angle between the first clamping part  101  and the second clamping part  103 , enhancing the deformability of the clamping part when it is opened; in this respect, it is not easy to break the fitting seat  1 , increasing the stability of the fitting seat  1 . Of course, it can be understood that the third bending portion  102  may also be in other shapes, which are not limited herein. 
     It shall be noted that the fitting seat  1  in this embodiment can be applied not only to a vehicle seat, but also to other products, as long as the fitting seat  1  can be fixed in a certain position. 
     Furthermore, the fitting  1  may further include third bending portions  102  and second clamping parts  103 . The first clamping parts  101  are connected to the second clamping parts  103  via the third bending portions  102 ; and the second clamping parts  103  and the first clamping parts  101  are symmetrically arranged to form a clamping space  104 . With the formed clamping space  104 , when the fitting seat  1  is clamped the connecting rods  3 , the connecting rods are located within the clamping space  104  to be clamped by the first clamping parts  101  and the second clamping parts  103 , making the fitting seat  1  better clamp the connecting rods  3  and not be easy to fall off from the connecting rods  3 , thereby increasing the stability of the fitting seat  1 . In this way, the two ends of the fitting seat  1  are bent to form the clamping space  104  to clamp the connecting rod  3  more tightly, hence the fitting seat  1  is simple in structure. 
     Furthermore, each of the second clamping part  103  has a fourth bending portion  103   a  and a fifth bending portion  103   b.  One end of the fourth bending portion  103   a  is connected to the third bending portion  102 , and the other end is connected to the fifth bending portion  103   b.  One end of the fifth bending portion  103   b  away from the fourth bending portion  103   a  is inclined in a direction opposite to the bending direction in which the fifth bending portion bends. In this way, each connecting rod  3  can be easily put into the clamping space  104 , facilitating the fitting seat  1  to clamp the connecting rod  3 . 
     The interconnecting piece  10 , the first clamping parts  101 , the third bending portions  102 , and the second clamping parts  103  are made of elastic materials; in this way, the deformability of the fitting seat  1  can be increased. Such elastic force of the deformation makes each first clamping part  101  and each second clamping part better clamp each connecting rod  3 . Moreover, due to the strong deformability, when the distance between the connecting rods  3  changes, the fitting seat  1  may be adapted to the change of the distance between the connecting rods  3  due to the deformation; thus matching more car seats of different sizes. 
     Furthermore, the clamping space  104  at each side has an opening  105  facing toward the interconnecting piece  10 . The opening is wide close to the clamping space and is narrow away from the clamping space, so that it is not easy for the fitting seat  1  to slip off from the connecting rods  3 . 
     Furthermore, as shown in  FIG. 2 , skidproof stripes  106  are provided on the inner side of each second clamping part  103 ; in this respect, the sliding friction of the fitting seat  1  may be increased, making the fitting seat  1  not easily to be slipped off the connecting rod  3 . In this embodiment, the skidproof stripes  106  are arranged at the rear of each second clamping part  103  away from the third bending portion. 
     Furthermore, the second clamping parts  103  each are arranged on one side in a direction in which the two first clamping parts  101  are away from each other. In this way, when a user sits behind a seat of the vehicle, it is convenient for the user to clamp the fitting seat  1  on the connecting rods  3  of the backrest of the seat. 
     Furthermore, as shown in  FIG. 2 , a plurality of recesses  107  are provided on the interconnecting piece  10  to make the fitting seat  1  beautiful and reduce the weight thereof. 
     Furthermore, the coupling head  11  may include a connecting arm  111  coupled to the interconnecting piece  10  and a universal ball  112  coupled to the connecting arm  111 . The mounting base  2  is connected with the universal ball  112 . By setting the universal ball  112 , the mounting base  2  can be rotated  360  degrees. It shall be noted that the coupling head  11  can be used to hang objects, not necessarily connected to the mounting base  2 . 
     A holder provided according to a second aspect of the embodiment may include the fitting seat  1  and the mounting base  2  mentioned above, as shown in  FIG. 3 ; in this respect the coupling head  11  is connected to the mounting base  2 . 
     In this embodiment, the interconnecting piece  10  and the coupling head  11  are integrally arranged. For details, please refer to the description mentioned above, which will not be repeated here. 
     The present disclosure may be described in detail with reference to the above specific optional embodiments, but the specific implementation of the present disclosure is not limited to such descriptions. A plurality of deductions or substitutions made to the present disclosure by those skilled in the art without departing from the concept of the present disclosure should be regarded as belonging to the protection scope of the present disclosure.
