Padlock spare (3) rotate arrive spacing arch (301) with spacing step (102) are relative, dial button (4) can stretch into when moving left in dial button groove (103) make in spacing groove (302) on padlock spare (3) locking, dial button (4) are deviate from when moving right in dial button groove (103) make in spacing groove (302) on padlock spare (3) unblock.
The lockhole (303) is in the padlock spare (3) rotates the in-process can be located lock (5) are equipped with to shell (1) outside.
The elastic bulge (401) of the toggle button (4) is of a circular arc-shaped bulge structure which faces downwards and is far away from the direction of the padlock part (3).
The padlock structure of the circuit breaker provided by the invention realizes the installation positioning and the rotation limiting of the padlock part by utilizing the circular rotary structure of the electric operating handle, and the padlock is positioned in a single direction by utilizing the clamping block of the manual and automatic selection switch toggle button and the limiting groove on the shell.

Detailed Description
The present invention will be described with reference to the following embodiments and accompanying drawings.
In order to achieve the purpose, the invention adopts the following solution: the utility model provides a padlock structure of circuit breaker, it includes shell (1), and electricity handle (2) dress can rotate in handle mounting groove (101) on shell (1), and padlock spare (3) suit is in can rotate around electricity handle (2) on electricity handle (2), as shown in figure 2, be equipped with spacing arch (301) in the outer fringe of padlock spare (3), as shown in figure 4, shell (1) go up with spacing arch (301) correspond and are equipped with spacing step (102), spacing step (102) are through the restriction thereby spacing arch (301) are restricted the rotation stroke of padlock spare (3), as shown in figures 1, 3 and 5, dial button (4) dress is in can come the return motion in dial button groove (103) on shell (1), dial button (4) are in can stretch into or deviate from during the return motion in dial button groove (103) make in spacing groove (302) on the padlock spare (3) lock or unblock padlock spare (3) and the utility model discloses a lock, be equipped with lockhole (303) on padlock spare (3), thereby can be equipped with lock (5) in lockhole (303) and make its self locking realize dying to the lock of electrical manipulation handle (2), the lower part of dialling button (4) still is equipped with elastic bulge (401), the top and the shell (1) contact of elastic bulge (401) of dialling button (4), make and dial button (4) and produce the elastic thrust to padlock spare (3) direction motion all the time.
