In some of these embodiments, the sixth locking element 605 is removably coupled to the third support element 601 or the sixth support element 603.

In some of these embodiments, the sixth locking element 605 is threadably coupled to the third support element 601 or the sixth support element 603.

In some of these embodiments, the sixth locking element 605 is a third press lock block.

In some of these embodiments, the sixth locking element 605 is a third locking screw.

In one embodiment, the fifth locking element 604 is disposed at the first end of the third supporting element 601 and is a third locking screw hole, and the sixth locking element 605 is in threaded connection with the third supporting element 601 and is a first locking screw. The third supporting element 601 has a hollow structure, and the sixth supporting element 603 has a solid structure; the sixth locking element 605 is threadedly coupled to the fifth locking element 604, and the outer diameter of both ends of the sixth locking element 605 is greater than the diameter of the fifth locking element 604; in the locked condition, one end of the sixth locking element 605 abuts against the sixth supporting element 603, and at this time, the third supporting element 601 and the sixth supporting element 603 cannot slide; in the unlocked state, one end of the sixth locking member 605 is separated from the sixth supporting member 603, and at this time, the third supporting member 601 and the sixth supporting member 603 can slide.

In one embodiment, the fifth locking element 604 is disposed at a second end of the sixth supporting element 603 at intervals along the length of the sixth supporting element 603 and is a third locking hole, and the sixth locking element 605 is fixedly connected to the third supporting element 601 and is a second pressing locking block, and is slidably connected to a fifth locking element 604. The third supporting element 601 is of a solid structure, and the sixth supporting element 603 is of a hollow structure; the outer diameter of sixth locking element 605 is less than or equal to the diameter of fifth locking element 604; in the locked condition, the sixth locking element 605 enters a fifth locking element 604 and protrudes from the fifth locking element 604, at this time, the third supporting element 601 and the sixth supporting element 603 cannot slide; in the unlocked condition, the sixth locking element 605 is disengaged from the fifth locking element 604, at which point the third support element 601 and the sixth support element 603 can slide.

The application method of the embodiment is as follows:

fixing the second support member 401 to the first palm fixing member 102 via the connection of the third locking connection member 402 to a first locking connection member 104, and fixing the connection of the third locking connection member 402 of the fifth support member 403 to a second locking connection member 204 to the arm fixing member 202; at this time, the fixation between the rear end of the palm and the forearm is completed;

according to the length of the palm of the patient, the positions of the third supporting element 601 and the sixth supporting element 603 are adjusted through unlocking the sixth locking element 605 and the fifth locking element 604, so that the length of the limit connection unit 600 is adjusted;

the third support element 601 is fixed to the first palm fixing element 102 through the connection between the third limit connecting element 602 and the first limit connecting element 106, and the connection between the third limit connecting element 602 and the second limit connecting element 503 of the sixth support element 603 is fixed to the second palm fixing element 502; at this time, the fixation between the front end of the palm and the rear end of the palm is completed.

The advantage of this embodiment is that the fixing of different positions can be realized by adjusting the length of the spacing connection unit, thereby being applicable to different patients.
