In figure: transfer arm joint portion 1, transfer arm 2, bearing pin 3, the hand-held ring 4 of fixed arm, the hand-held ring 5 of transfer arm, fixed arm 6, scale 7, fixed arm joint portion 8.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further.
The disclosed this remporomandibular joint angle measuring scale of the present embodiment is made up of chi head, blade and chi tail, and chi head is joint portion, and blade is gage beam, and chi tail is hand-held ring.Concrete structure is referring to accompanying drawing 1-2.
It is identical with transfer arm 2, two arm configurations that gage beam is divided into fixed arm 6, long 15cm, width 0.5-1cm respectively, the platy structure of thickness 2mm.In order to reach the object of measuring accurately, being convenient for measuring, afterbody and the head end of fixed arm 6 and transfer arm 2 are provided with ennation, and it is chi head that head end arranges joint portion, and it is chi tail that tail end arranges hand-held ring.
Long 1.5cm as the joint portion of subsidiary part, the rectangular flat of wide 0.5cm, joint portion and gage beam are perpendicular, and the plane of joint portion and gage beam plane are at an angle of 90.Joint portion is made up of transfer arm joint portion 1 and fixed arm joint portion 8, and the front end of transfer arm 2 is fixedly connected with transfer arm joint portion 1, and the front end of fixed arm 1 is fixedly connected with fixed arm joint portion 8.Hand-held ring is divided into the hand-held ring 4 of fixed arm and the hand-held ring 5 of transfer arm, and the tail end of transfer arm 2 is fixedly connected with the hand-held ring 5 of transfer arm, and the tail end of fixed arm 6 is fixedly connected with the hand-held ring 4 of fixed arm.
