A groove 402 is provided at one end of the splicing block 302. A pin 303 is fixedly connected to the splicing base 301. A pressing plate 304 is rotatably connected to the splicing base 301.
[0023] As a technical optimization solution of the present invention, the cross-section and vertical section of the splicing base 301 are both in an I-shaped structure, and the protruding block 401 and the groove 402 are engaged; thus, it is convenient to limit the position where the splicing block 302 and the splicing base 301 are clamped.
[0024] As a technical optimization solution of the present invention, a contact block 305 is fixedly connected to one side of the splicing base 301, and a clamping block 306 is fixedly connected to the top end of the pressing plate 304; the right side of the cross-section of the contact block 305 is in an arc structure, and one side of the clamping block 306 is in an arc structure. The arc side of the clamping block 306 can be in contact with the arc side of the contact block 305; thus, it is convenient to fix the pressing plate 304 above the splicing block 302 by the plane at the bottom end of the contact block 305 and the contact of the clamping block 306.
[0025] As a technical optimization solution of the present utility model, a silica gel pad 307 is installed on one side of the inner wall of the pressing plate 304, and a elastic sheet is fixedly connected between the silica gel pad 307 and the inner wall of the pressing plate 304; thus, it is convenient to press the first circuit board 1 or the second circuit board 2 in the splicing block 302 through the silica gel pad 307.
[0026] As a technical optimization solution of the present utility model, fixing blocks 403 are slidably connected to the peripheries of the top and bottom of the splicing base 301, springs are fixedly connected between the fixing blocks 403 and the splicing base 301, and friction pads 404 are fixedly connected to the bottoms of the fixing blocks 403; the cross-section of the fixing block 403 is in a T-shaped structure, and one end of the friction pad 404 is in a wavy structure; pressing blocks 405 are slidably connected to the peripheries of the top and bottom of the splicing base 301, elastic sheets are fixedly connected between the pressing blocks 405 and the splicing base 301, and a pulling rope 406 is fixedly connected between the fixing blocks 403 and the pressing blocks 405; a roller 407 is rotatably connected in the splicing base 301, and the pulling rope 406 is in rolling connection with the roller 407; thus, it is convenient to snap the splicing block 302 onto the splicing base 301.
[0027] As a technical optimization solution of the present utility model, a guide rod 408 is fixedly connected in the splicing base 301, and the guide rod 408 is slidably connected to the fixing block 403; thus, it is convenient to limit the fixing block 403 when the fixing block 403 slides.
[0028] When the utility model is in use, first, one end of the first circuit board 1 and the second circuit board 2 are respectively inserted into the pins 303 on the splicing block 302. Subsequently, the pressing plate 304 on the splicing block 302 is pressed, so that the arc-shaped end of the clamping block 306 at one end of the pressing plate 304 abuts against the abutting block 305 on the splicing block 302, causing the clamping block 306 to deform. When the pressing plate 304 is clamped on the splicing block 302, the pressing plate 304 is limited by the plane at the bottom end of the abutting block 305 where one end of the clamping block 306 abuts. The first circuit board 1 or the second circuit board 2 is pressed tightly in the splicing block 302 by the pressing plate 304 to prevent it from falling off. Moreover, when the pressing plate 304 is clamped on the splicing block 302, the silica gel pad 307 on the inner wall of the pressing plate 304 can abut against the first circuit board 1 and the second circuit board 2, extruding the first circuit board 1 and the second circuit board 2 to increase the stability of their splicing and avoid loosening. Subsequently, the splicing block 302 installed with the first circuit board 1 and the second circuit board 2 is inserted into the empty slot on the splicing base 301. At the same time, the pressing block 405 on the splicing base 301 is pressed, and the fixed block 403 is driven by the pulling rope 406 on the pressing block 405 to compress the spring and slide in the splicing base 301. Subsequently, the protrusion 401 on the splicing base 301 is engaged with the groove 402 on the splicing block 302 to limit the splicing block 302. When the splicing block 302 is clamped on the splicing base 301, the pressing block 405 is released. At this time, the spring between the fixed block 403 and the splicing base 301 can reset the fixed block 403, so that the friction pad 404 on the fixed block 403 clamps the splicing block 302. Thus, the first circuit board 1 and the second circuit board 2 can be spliced by the splicing block 302 and the splicing base 301. Moreover, during splicing, the clamping positions of the splicing block 302 and the splicing base 301 can be adjusted according to user needs, enabling the first circuit board 1 and the second circuit board 2 to be spliced linearly or at an angle, which is convenient for use.
