DETAILED DESCRIPTION

[0020] The present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] FIG. 1 shows a circuit breaker handle connection mode, comprising a handle 1 and a lever 2, in the embodiment, the lever 2 is in a U shape. The handle 1 and the lever 2 are assembled together, here, a mounting recess 102 is arranged at a bottom of a handle disc portion 101 of the handle 1, a bottom 201 of the lever 2 is mounted in the mounting recess 102 and can rotate, the bottom of the lever 2 outstretches a positioning boss 202, when the lever 2 rotates to a fixed position in the mounting recess 102, the degrees of freedom of the positioning boss 202 are limited by a limiting-position boss 103 so that it is mounted in the mounting recess 102. Further, a limiting-position buckle 104 can be additionally arranged to further limit the degrees of freedom so that it can be fixedly mounted in the mounting recess 102. In the embodiment, the number of the limiting-position bosses 103 is two, they are symmetrically arranged on outer side end surface of recess wall of the mounting recess 102. The number of the limiting-position buckles 104 are two, they are symmetrically arranged on the outer side end surface of the recess wall of the mounting recess 102.

[0022] As shown in FIG. 2, the limiting-position boss 103 comprises a limiting-position transverse boss 103a, the limiting-position transverse boss 103a extends from the outer side end surface of the recess wall of the mounting recess 102 to the inside of the recess, the limiting-position transverse boss 103a outstretches a limiting-position vertical boss 103b to a bottom of the mounting recess 102, when a bottom 201 of the lever 2 rotates to a fixed position in the mounting recess 102, the positioning boss 202 is inserted into a space formed by the limiting-position transverse boss 103a, the limiting-position vertical boss 103b and the bottom surface of the mounting recess 102, so that the lever 2 is fixedly mounted in the mounting recess 102.

[0023] As shown in FIG. 2, the limiting-position buckle 104 is arranged on the outer side end surface of the recess wall of the mounting recess 102, an end of the limiting-position buckle 104 is arranged on the end surface of the outer side of the recess wall of the mounting recess 102, there is a gap 105 between another end and the end surface of the outer side of the recess wall of the mounting recess 102 so that deformation can be generated, when the lever 2 is located at a fixed position, the end of the limiting-position buckle 104 which generates deformation resists against the side wall 203 of the lever 2 so that it cannot rotate back.

[0024] As shown in FIG. 4, first, the lever 2 is inserted into the mounting recess 102, then the lever 2 is rotated, during the process when the lever 2 is rotating, the lever 2 presses the limiting-position buckle 104 downwards so that it can't resist the rotation of the lever 2, as shown in FIG. 5, when the positioning boss 202 of the lever 2 rotates so that it is resisted against by the limiting-position transverse boss 103a and the limiting-position vertical boss 103b, the degrees of freedom of reverse rotation of the lever 2 can be limited by the limiting-position buckle 104 which is bounced and restored to an original position, the position where the lever 2 is located now is a fixed position, in the embodiment, the number of the positioning bosses 202 are two, they are symmetrically arranged at the two side ends of the bottom of the lever 2, so that reliable mounting between the lever and the handle can be better ensured.
