The shell (1) is provided with a round wire outlet hole and a long wire outlet hole, the rotating shaft (10) is a hollow shaft, and the telescopic end (4) of the grounding wire is wound on the winding drum (12) and extends out of the long wire outlet hole; the fixed end (5) of the grounding wire passes through the holes on the winding drum (12) and the rotating shaft (10), penetrates out along the inner end of the rotating shaft (10), and then extends out through the circular wire outlet hole.
The rotating shaft (10) is fixedly connected with a rotating disc (6) extending out of the shell (1), a round hole is formed in the rotating disc (6), one end of a connecting handle (3) can be detached from the round hole, and a limiting block (16) is arranged on the handle (3). The rocking handle (3) may be used to assist in the stretching of the ground wire.
The other end of the handle (3) is provided with a pin shaft (17), the left side wall and the right side wall of the shell (1) are provided with a circle of pin holes (15), and the pin shaft (17) penetrates through a round hole in the turntable (6) and can be connected with the pin holes (15) in a matched mode.
And a baffle (14) is arranged in the shell (1) at a position opposite to the pin hole (15).
When flexible end (4) winding state of earth connection, roll up spring (11) and be in lax state, flexible end (4) of pulling can make roll up spring (11) and compressed, for preventing flexible end withdrawal, use round pin axle (17) to pass round hole on carousel (6) and be connected with pinhole (15) cooperation, can prevent pivot (10) and rotate to prevent flexible end (4) withdrawal.
The utility model has the beneficial effects that: the retractable wire take-up assembly is reasonable in structure, flexible and convenient to operate, and capable of accommodating and diffusing the ground wire for use quickly and stably, and damage to the ground wire due to improper winding of the ground wire is avoided.
