[0022] The specific operation is as follows: the driving shaft 402 and the driving gear 403 are driven to rotate by the servo motor 401, and the driving gear 403 drives the driven gear 1 404 and the driven gear 2 406 to rotate the screw rod 1 405 and the screw rod 2 407, so that the two screw nuts 408 drive the moving plate 409 to move outside the screw rod 1 405 and the screw rod 2 407 respectively, and the effect of detecting the circuit breaker spring outside the sleeve 411 is completed by continuously reducing the distance between the moving plate 409 and the fixed plate 2 3.

[0023] like Figure 1 As shown, a fixing plate 2 is fixed to the left side of the surface of the box cover 1, and a fixing plate 2 3 is fixed to the right side of the surface of the box cover 1, a box body 9 is hinged on one side of the box cover 1, and a display screen 10 is installed on the top surface of the box body 9, a buckle 11 is fixed to the middle part above the front end of the box body 9, and a data collector 12 is arranged on the left side of the box body 9, a display 5 is arranged on the side of the box cover 1 close to the box body 9, and a strap 6 is fixed to the edge of the box cover 1, a strap 2 7 is sewn on the surface of the strap 6, and an anti-slip pattern 8 is arranged on the surface of the strap 6.

[0024] The specific operation is as follows: pass the strap 1 6 through the buttonhole of the buckle 11, so that the user can hold the box body 9 by passing his hand through the gap between the strap 1 6 and the strap 2 7.
