Specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, it is embodied as to according to rotation protection cap positioner proposed by the present invention
Mode, structure, feature and its effect, after describing in detail such as.
Referring to Fig. 1 to Fig. 8, the rotation protection cap positioner of the present invention, comprising: installing plate 1, panel 2, group handle 4, protection
Lid 5, equipped with panel 2 above installing plate 1, in the middle part of panel 2 equipped with protection cap 5 it is characterised in that: be fixedly connected with protection cap 5
Dial handle 4, protection cap 5 is provided with groove 6, is flexibly connected between panel 2 and protection cap 5.Fill between described protection cap 5 and panel 2
There is steel ball 7.Described protection cap 5 is connected by screw a3 with dialling handle 4.Described group of handle 4 is in 180 ° of arrangements around protection cap 5 center.
Described group of handle 4 is two.The bottom of described installing plate 1 is equipped with screw b9.Equipped with adjusting pad between described installing plate 1 and screw b9
Circle 8.Described groove 6 is two ends rectangular channel with rounded corners.
During use, if the handle 4 of dialling in rotation protection cap 5 makes groove 6 towards " packing up " position, undercarriage control controlling switch 10
