Said handle and connecting rod is made of handle and connecting rod, is provided with contiguous block between handle and the connecting rod, is provided with spring in the contiguous block, and both ends of the spring is provided with steel ball, and the two ends of contiguous block flexibly connect with handle and connecting rod respectively by pin; When dismounting off-premises station foot-screw, can make handle do the right angle fold of different directions as required.

In order to prevent that the utility model is slipped out of the hand to be lost, the end of said handle is provided with anti-decylization; But anti-decylization bolt rope sling also can be used as the stress point of external force with slip-off preventing, can insert instrument such as screwdriver during use and make the dismounting screw more laborsaving to turn connecting rod.

The long 40cm of said extension bar can also can use the more piece extension bar without extension bar according to the size of machine, the height of off-premises station in actual the use.

The forearm that the sidewall outside, said sleeve pipe lower end is fixedly connected and the sleeve of its end, fixedly connected by screw.

Said sleeve is interchangeable, according to the size of off-premises station foot-screw, can select plurality of specifications for use.

Connect easy accessibility between the utility model simple structure, easy to use, each bar, be easy to carry; Because the embedded annular magnet of sleeve, screw and pad or nut can be held during the dismounting screw and be convenient to dismounting.During installation, will put into the screw of nut, cover Upper gasket in two sleeves respectively, turning handle can be fixed screw and nut; During dismounting, two sleeves are aimed at off-premises station footing nut, screw respectively, and the backward rotation handle can unload screw and nut; The utility model dismounting air-conditioner outdoor unit foot-screw labour intensity is little, high efficiency.
