     In order to facilitate understanding of those skilled in the art, the invention is further described below with reference to embodiments and the drawings, and contents involved in implementation modes are not intended to limit the invention. 
     Embodiment 1 
     As shown in  FIG. 1  to  FIG. 5 , an LED lamp bead wire clamping mounting structure includes a mounting seat  1  and wire clamping parts  2 , wherein the mounting seat  1  is provided with two accommodation grooves  11  for mounting the wire clamping parts  2  and a mounting groove  12  for mounting an LED lamp bead; the wire clamping parts  2  are arranged in the accommodation grooves  11 ; each wire clamping part  2  is provided with a bottom wall  21 , a lamp bead connecting terminal  22  connected with the bottom wall  21 , two sidewalls  23  upwards extending from the bottom wall  21  and a crosswise-folded clamping piece  24  connected with one sidewall  23 ; and the crosswise-folded clamping pieces  24  extend to the other sidewalls  23 . 
     Specifically, the mounting seat  1  is integrally formed from plastics, the wire clamping parts  2  are conductive metal parts, the mounting seat  1  is provided with the two accommodation grooves  11 , the wire clamping parts  2  are arranged in the two accommodation grooves  11 , and the two wire clamping parts  2  are correspondingly connected with positive and negative terminals of an LED lamp bead  10  to facilitate the connection of the positive and negative terminals of the LED lamp bead  10  respectively. 
     During a practical application, the LED lamp bead  10  is mounted in the mounting groove  12 , and when the positive and negative terminals of the LED lamp bead  10  are connected with the wire clamping parts  2  respectively, the lamp bead connecting terminals  22  of the wire clamping parts  2  are attached to the positive and negative terminals of the LED lamp bead  10 ; and then external wires are clamped with the wire clamping parts  2 , specifically, the crosswise-folded clamping pieces  24  are inwards pressed by hands to be bounced away from the sidewalls  23  by certain wire clamping spaces, connecting ends of the wires are placed in the wire clamping spaces, and then the crosswise-folded clamping pieces  24  are loosened to be reset, thereby clamping the wires between the crosswise-folded clamping pieces  24  and the sidewalls  23  to further realize the connection of the wires of the LED lamp bead  10 . 
     According to the invention, the wire clamping parts  2  are adopted to clamp the wires of the LED lamp bead  10 , so that the LED lamp bead wire clamping mounting structure is convenient to connect, mount, dismount, assemble and repair, time is saved, and connection efficiency is improved; the wires are prevented from being connected in a welding manner, so that use of tools and fixtures as well as a welding material is avoided, production cost is lowered, energy is saved, and the environment is protected; and in addition, the mounting seat  1  is integrally formed, so that the LED lamp bead wire clamping mounting structure is compact, small in size and high in structural stability and practicability. 
     In the embodiment, each wire clamping part includes two crosswise-folded clamping pieces  24 . Specifically, as shown in  FIG. 4 , the two crosswise-folded clamping pieces  24  of each wire clamping part may be arranged on the corresponding two sidewalls  23  respectively; and as shown in  FIG. 5 , the two crosswise-folded clamping pieces  24  of each wire clamping part may also be arranged on the same sidewall  23 . The arrangement of the two crosswise-folded clamping pieces  24  of each wire clamping part means that the same wire clamping part  2  has two wire clamping positions, so that series and parallel connection of the LED lamp bead  10  is facilitated, and the LED lamp bead wire clamping mounting structure is wide in application range and high in practicability. 
     In the embodiment, the bottom walls  21  are provided with positioning bumps  25  for blocking the crosswise-folded clamping pieces  24 , and the positioning bumps  25  are positioned in the spaces formed by the crosswise-folded clamping pieces  24  and the sidewalls  23 . When the crosswise-folded clamping pieces  24  are pressed by hands, the positioning bumps  25  block the crosswise-folded clamping pieces  24  to prevent the condition that the crosswise-folded clamping pieces  24  are excessively deformed by excessive force and may not be bounced back, ensure that the crosswise-folded clamping pieces  24  are deformed within a certain range and prolong the service life of the wire clamping parts  2 . 
     In the embodiment, the mounting seat  1  is provided with wire passing grooves  13 , and the wire passing grooves  13  are communicated with the accommodation grooves  11 . Specifically, the wire passing grooves  13  are formed in front and rear sides of the mounting seat  1  to facilitate the arrangement of the wires. During use, the wires enter the accommodation grooves  11  through the wire passing grooves  13 , and are clamped between the crosswise-folded clamping pieces  24  and the sidewalls  23 . 
     In the embodiment, the mounting seat  1  is provided with nicks  14  for extension of the lamp bead connecting terminals  22 , and the nicks  14  are communicated with the accommodation grooves  11 .

The cover plates  3  are integrally formed from plastics, the cover plates  3  seal the wire clamping parts  2  in the accommodation grooves  11  for fixation, and in addition, the cover plates  3  may insulate the wire clamping parts  2  in an energy-saving manner to ensure safety in use. When the LED lamp bead wire clamping mounting structure is mounted, outer surfaces of the cover plates  3  and a mounting surface of the mounting seat  1  are in the same direction, that is, the outer surfaces of the cover plates  3  and the mounting surface of the mounting seat  1  are in the same plane, so that stability of the wire clamping parts  2  is further ensured. 
     In the embodiment, cover plate platforms  5  are arranged on edges of the accommodation grooves  11 , the cover plate platforms  15  are provided with convex pins  16 , the cover plates  3  are provided with pinholes  31  matched with the convex pins  16 , the cover plates  3  are arranged on the cover plate platforms  15 , and the convex pins  16  are arranged in the pinholes  31  in a penetration manner.

     In the embodiment, wire through grooves  32  are formed in the bottoms of the cover plates  3 . During mounting, the wire through grooves  32  are buckled to the wire passing grooves  13  of the mounting seat  1  to form complete wire through holes, and the wire through holes guide and fix the wires to ensure regular wiring. 
     Embodiment 2 
     As shown in  FIG. 6 , a difference between embodiment 2 and embodiment 1 is as follows: each wire clamping part is provided with one crosswise-folded clamping piece  24 . Specifically, the same wire clamping part  2  has only one wire clamping position, so that the LED lamp bead wire clamping mounting structure is more compact, small in size and low in production cost, and different market requirements are met.
