Further, the angle that described two the first steel balls and the first groove center form is 270 °.
Further, described the first steel ball is Ф 2mm steel ball.
Further, described securing member is holding screw.
Further, described outer tube top is step-like, and two the second steel balls are fixedly welded on the step surface on outer tube top.
Further, the angle that described two the second steel balls and step surface center form is 270 °.
Further, described the second steel ball is Ф 2.5mm steel ball.
Further, the periphery of described elastomer joint also has the second groove, and O type circle is housed in the second groove.
Further, in the periphery of described demonstration housing, have the 3rd groove, O type circle is also housed in the 3rd groove.
Use the utility model, elastomer joint can be rotated between two the first steel balls, shows that housing can rotate between two the second steel balls; Both match and can realize product and use within the scope of 360 °, guarantee that product can work in the occasion of the narrow and small fitting operation inconvenience of some operating modes smoothly, can provide display direction and wiring easily easily to operate, and have strengthened the installation practicality of product.
