[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0021] like Figure 1-Figure 4 As shown, an adjustable hand-free frame for connecting a head frame comprises a frame 1, an adjusting frame 2 and a supporting platform 3, wherein the adjusting frame 2 is movably inserted into the interior of the frame 1, the supporting platform 3 is connected to one end of the adjusting frame 2, connecting strips 4 are respectively connected to the two sides of the frame 1, one side of the connecting strip 4 is connected to a first fixing frame 5, the interior of the first fixing frame 5 is slidably connected to a sliding block 6, the interior of the first fixing frame 5 is connected to a limiting rod 7, the limiting rod 7 passes through the sliding block 6 and is slidably connected to the sliding block 6, one side of the sliding block 6 is connected to a clamping block 8, one side of the clamping block 8 is provided with a first threaded hole 9, the interior of the first threaded hole 9 is threadedly connected to a first bolt 10, the top surface of the first fixing frame 5 is provided with a circular groove for connecting a driving motor 11, and the first fixing The top surface of the frame 5 is embedded with a driving motor 11, one end of the driving shaft of the driving motor 11 is connected to a rotating wheel 12, the inner circular wall of the rotating wheel 12 is connected to a thin steel cable 13, both ends of the thin steel cable 13 are respectively connected to one side of the clamping block 8, the top surface of the sliding block 6 is connected to a connecting rod 23, the connecting rod 23 is connected to the thin steel cable 13, the top surface of the first fixed frame 5 is connected to the second fixed frame 14, the top surface of the second fixed frame 14 is provided with a limiting hole 15, the internal rotation of the limiting hole 15 is connected to a rotating column 16, the rotating column 16 is connected to the top of the rotating wheel 12, a second threaded hole 17 is provided on one side of the bracket 1, the internal thread of the second threaded hole 17 is threadedly connected to a second bolt 18, and a plurality of threaded grooves 19 are provided on one side of the adjusting frame 2.
[0022] During use, the set driving motor 11 is started, and the driving shaft of the driving motor 11 rotates to drive the rotating wheel 12 to rotate, so that the thin steel cable 13 can be reeled in, so that the sliding block 6 and the clamping block 8 are both pulled by force. At this time, the clamping block 8 slides on the outer circular wall surface of the limit rod 7 through the sliding block 6, so that the clamping block 8 moves upward until the two clamping blocks 8 are respectively combined with the edge of the head frame and the edge of the operating table. At this time, the first bolt 10 can be rotated to enter the inside of the first threaded hole 9, so that the clamping block 8 can be connected with the edge of the head frame and the edge of the operating table. At this time, the adjustment After the height of the section frame 2 is adjusted, the second bolt 18 is rotated to the inside of the second threaded hole 17 and the threaded groove 19 to fix the adjustment frame 2, which is convenient for adapting to operating tables of different heights. Then the patient can put his arm inside the support table 3.

At this time, the clamping block 8 slides on the outer circular wall surface of the limit rod 7 through the sliding block 6, so that the clamping block 8 moves upward until the two clamping blocks 8 are respectively combined with the edge of the head frame and the edge of the operating table. At this time, the first bolt 10 can be rotated to enter the inside of the first threaded hole 9, and the clamping block 8 can be clamped with the head frame. The edge of the frame and the edge of the operating table are connected together, and the height of the adjustment frame 2 can be adjusted at this time. After the adjustment is completed, the second bolt 18 is rotated to the inside of the second threaded hole 17 and the threaded groove 19 to fix the adjustment frame 2, which is convenient for adapting to operating tables of different heights. Then the patient can put his arm inside the support table 3. In this solution, the clamping block 8 is driven to move by winding up the thin steel cable 13 and the clamping block 8 is adjusted to a certain height and then connected to the edge of the operating table and the edge of the head frame, thereby ensuring the stability of the support table 3 during use, avoiding excessive movement of the hand frame under the active action of the patient, affecting the patient's treatment, and at the same time, the adjustable height adjustment frame 2 is used to adapt to different operating table heights, which is more practical.
