Detailed Description

Specific embodiments thereof are described below in conjunction with the following description and the accompanying drawings to teach those skilled in the art how to make and use the best mode of the present application. For the purpose of teaching application principles, the following conventional aspects have been simplified or omitted. Those skilled in the art will appreciate variations from these embodiments that fall within the scope of the application. Those skilled in the art will appreciate that the features described below can be combined in various ways to form multiple variations of the present application. In the present application, the terms "upper", "lower", "left", "right", "middle" and "one" are used for clarity of description, and are not used to limit the scope of the invention, and the relative relationship between the terms and the corresponding terms may be changed or adjusted without substantial technical change. Thus, the present application is not limited to the specific embodiments described below, but only by the claims and their equivalents.

As shown in fig. 1, the embodiment relates to an insulating connecting device for a push rod assembly of a grass mower, wherein an upper push rod 1 and a lower push rod 2 form the push rod assembly of the grass mower, the lower end of the upper push rod 1 is connected with the upper end of the lower push rod 2 through the insulating connecting device, and the insulating connecting device comprises a U-shaped buckle 3, an insulating gasket 4 and a locking knob 5; insulating gasket 4 adopts is the working of plastics, and U type knot 3 is the stainless steel, insulating gasket 4 locate between push up rod 1 and push down pole 2, keep apart push up rod 1 and push down pole 2's contact surface, the both ends that U type detained 3 all pass the connecting rod body of push up rod 1, the connecting rod body of insulating gasket 4 and push down pole 2, and insulating gasket 4 still keeps apart U type knot 3 and push down pole 2's contact surface, the U type is detained 3 wherein one end and is passed through locking knob 5 locks fixedly.
