Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 to 11, the on-off indicating plate of the pole switch includes an on-off indicating shaft 100, an adjusting compass 200, a pointer 300, a spacer 400, a spring washer 401 and a screw 402.

The utility model discloses a gear revolve angle regulation principle. A square limiting boss 103 is milled on the end surface 102 of the opening and closing indication shaft 100, and a threaded hole 104 is drilled in the center of the square limiting boss 103. The side length a1 of the square limit boss 103 is equal to the side length B1, the thickness of the square limit boss 103 is L1, and the inner diameter of the threaded hole 104 is C. A chamfer 101 is milled at one periphery of the square limiting boss 103 to serve as a positioning direction.

An inner insection 303 is machined at one end of the pointer 300 through laser cutting, the machined intermediate material is directly made into the adjusting compass 200, a circle of outer insection 202 is arranged on the outer circumference of the adjusting compass 200, the outer insection 202 is formed by uniformly and equally distributing a plurality of triangular teeth according to the axis, the angle between every two adjacent triangular teeth is D1, the inner insection 303 of the pointer 300 is formed by uniformly and equally distributing a plurality of triangular teeth according to the axis, the angle between every two adjacent triangular teeth is D2, D2 is D1, D1 and D2 can equally divide the angle according to deviation machining.
