Under shovel, to make the conducting wire for being connected to lug plate (30) as lug plate (30) are detached from；
The lower end surface of the screw shell (2) is equipped with support plate (22), the lower end of support plate (22) and roof supporting (26)
Face fits, and the upper surface of support plate (22) is equipped with the first ball (27), the lower end of the first ball (27) and roof supporting (26)
Face is in contact, and the first ball (27) rotates support plate (22) relative to the lower end surface of roof supporting (26), thus support plate
(22) it as screw shell (2) rotate, is moved up along threaded rod (21), roof supporting (26) is risen；Screw shell (2)
Upper end be connected with to connect cylinder (3), to the upper end opening of connect cylinder (3), for docking Electric drill-bit, to make screw shell (2)
As Electric drill-bit rotation is dismounted；
The endface all around of the support plate (25) is horizontal to be equipped with extension rod (28), and extension rod (28) is perpendicular to institute
In support plate (25) end face of position, extension rod (28) is located on the inside of support plate (25), and the inside level of support plate (25) is affixed
Have spring (29), spring (29) is connected with the end that extension rod (28) is on the inside of support plate (25), and spring (29) is in pressure
Contracting state, while the external end head of extension rod (28) is against on the inner sidewall of Battery case (1)；When support plate (25) and battery pack
(15) when falling off out of Battery case (1), the releasing that extension rod (28) is limited due to space, extension rod (28) is with spring (29)
Rebound reset response skid off support plate (25), increase support plate (25) support range, avoid support plate (25) with battery
Group (15), which is fallen to ground, topples over.
