When the combined connection structure main body 100 is combined to install the clamping component and the hand fixing pin, the movable adjustment reinforcement mechanism moves the fixing block 1013, and the clamping component and the fixing pin are fixedly installed inside the fixing block 1013, which is more tightened during fixed installation, and the tightening installation is strengthened, thereby improving the strengthened fixation of the combined installation when the combined connection structure main body 100 is combined to install the orthopedic hand external fixator.

[0028] In order to facilitate the rotation and adjustment of the position of the fixed block 1013 by rotating the adjustment component, and to facilitate the adjustment and fixed installation for use, in the present embodiment, preferably, the rotation and adjustment component includes grooves 1012 opened at both ends of one side inside the combined mounting plate 101, and the inside of the groove 1012 is rotatably connected with a screw rod 1017, and the end of the screw rod 1017 is located on the surface of the combined mounting plate 101 and a nut 1011 is installed, and the outer surface of the wrench engaging the nut 1011 drives the screw rod 1017 to rotate, which is convenient for rotation and adjustment, and a moving block 1014 is provided on the outer surface of the screw rod 1017 when the screw rod 1017 rotates. When the screw rod 1017 rotates, the moving block 1014 is located on the outer surface of the screw rod 1017 for movement and adjustment, in order to facilitate the screw rod 1017 to rotate and move and adjust the moving block 1014, when the moving block 1014 moves, it drives the fixed block 1013 to move and adjust to the installation position, and the end of the moving block 1014 extends to the inner side of the combined mounting plate 101, and the moving block 1014 is rotatably connected to the combined mounting plate 101 through the screw rod 1017, which is convenient for movement and adjustment.

[0029] In order to facilitate the fixed installation of the clamping part and the fixing pin through the reinforced installation component, and to strengthen the fixed installation, in this embodiment, preferably, the reinforced installation component includes fixed blocks 1013 arranged at both ends of the combined installation plate 101, and the side of the fixed block 1013 is fixedly connected to the end of the movable block 1014 by welding. In order to facilitate the installation of the clamping part and the fixing pin through the fixed block 1013, and to facilitate the reinforced installation and use, the fixed block 1013 is provided with a mounting hole, and the two fixed blocks 1013 are symmetrically arranged for easy fixed installation.

[0030] In order to facilitate the stable movement and adjustment of the fixed block 1013 by controlling the sliding component, in this embodiment, preferably, the controlled sliding component includes two sliding rods 1015 opened on the other side of the combined mounting plate 101, and the outer surface of the sliding rod 1015 is slidably connected with a slider 1016, and the end of the slider 1016 is fixedly connected to the end of the fixed block 1013 by welding. In order to drive the slider 1016 to slide on the outer surface of the sliding rod 1015 when the fixed block 1013 moves, so as to facilitate the stable movement and adjustment of the fixed block 1013, the sliding rod 1015 runs through the interior of the slider 1016, and the end of the fixed block 1013 is slidably connected to the sliding rod 1015 through the slider 1016 and the other side of the combined mounting plate 101 for stable control and adjustment.

[0031] A rolling mechanism includes a rolling assembly, which is arranged at the top edge of the connecting head 102. When the combined connection structure body 100 is installed and used, the end of the connecting rod 103 rotates inside the connecting head 102 through the rotating ball 104. At this time, when the connecting rod 103 rotates along the edge of the connecting head 102, the rolling mechanism rolls the end of the connecting rod 103, and it is difficult to rotate and friction damage occurs.

[0032] In order to facilitate the rolling protection when the end of the connecting rod 103 is rotated inside the connecting head 102 and contacts with the rolling protection through the rolling component, it is not easy to cause friction damage and it is stable for protection use, in this embodiment, preferably, the rolling component includes a rolling groove 1031 opened at the top edge of the inner part of the connecting head 102, and the inner rolling connection of the rolling groove 1031 is connected with a ball 1032.

[0033] The working principle and use process of the utility model are as follows: the combined structure of the orthopedic hand external fixator is used. When the hand fixing needle is fixedly installed at the injured part, the position of the fixing block 1013 is adjusted according to the position of the two fixing needles. The wrench is engaged with the outer surface of the nut 1011 to drive the screw rod 1017 to rotate. When the screw rod 1017 rotates, the moving block 1014 is located on the outer surface of the screw rod 1017 and moves. When the moving block 1014 moves, it drives the fixing block 1013 to move. When the fixing block 1013 moves, it drives the slider 1016 on the outer surface of the slider 1015. The surface sliding stably controls the movement of the fixing block 1013 until the fixing block 1013 is stably moved to the installation position, and the clamping component is fixedly installed inside the fixing block 1013 during installation and use, and the fixing pin is fixedly installed again through the clamping component, so that the combined connection structure body 100 is convenient to penetrate the inside of the fixing block 1013 when installing the clamping component and the fixing pin, and the clamping component and the fixing pin are more fixed when installed, thereby improving the combined installation of the combined connection structure body 100 when the orthopedic hand external fixator is installed;

[0034] Then, when the orthopedic hand external fixator is assembled and fixed by the combined connection structure main body 100, after a combined mounting plate 101 at one end of the combined connection structure main body 100 is fixed with the clamping component and the fixing pin, the angle of the other combined mounting plate 101 is adjusted according to the position of the fixing pin at the other end, and the rotating ball 104 is rotated inside the connecting head 102 to drive the connecting rod 103 to rotate, and the end of the connecting rod 103 is rotated and adjusted to the installation position, and the two combined mounting plates 101 are adjusted to different angles until the other combined mounting plate 101 is at the installation position of the fixing pin and fixed. During installation, the end of the connecting rod 103 is rotated on the surface of the connecting head 102 through the rotating ball 104. At this time, the end of the connecting rod 103 is on the surface of the connecting head 102. When the end of the connecting rod 103 is rotated along the inner surface of the connecting head 102, it contacts the surface of the ball 1032 and drives the ball 1032 to roll inside the rolling groove 1031. It is not easy to cause friction damage when the connecting head 102 is rotated, thereby improving the rolling protection effect of the combined connection structure main body 100 when the orthopedic hand fixation frame is combined and fixed, and extending the service life of the combined connection structure main body 100.

[0035] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
