The specific embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 1, the tapered end in the present embodiment comprises handle 3, the rotary bolt 4 that is made of elbow 1 and straight formula handle body 2, and is installed in outer washer 5 and inner washer 6 between handle 3 and the rotary bolt 4.Wherein, have fan-shaped tongue on the rotary bolt 4, be the ramped shaped of being with radian between the both sides of fan-shaped tongue.Elbow 1 and straight formula handle body 2 interference fit are together.On elbow 1, be provided with screw installing hole 7, on rotary bolt 4, be provided with corresponding screw 8, adopt 1 piece of hexagon socket head cap screw 9 elbow 1 and rotary bolt 4 mechanical connections can be got up.In the present embodiment, also be provided with a screw protecting cover 10 that is installed on the screw installing hole 7.
As shown in Figure 2, elbow 1 is provided with a regular hexagon prism 11.On the regular hexagon prism 11,, be the cylinder 12 that a size equates with the prismatic 11 circumscribed circle sizes of regular hexagon near the position of elbow 1.Screw installing hole 7 passes from the central authorities of regular hexagon prism 11.
As shown in Figure 3, a shape is arranged on the rotary bolt 4, and its screw 8 that connects hexagon socket head cap screw 9 is positioned at the central authorities of concave station 13 than the big slightly orthohexagonal concave station 13 of prismatic 11 gabarits of regular hexagon.Like this, after screwing hexagon socket head cap screw 9, elbow 1 is by the cooperation between regular hexagon prismatic 11 and the orthohexagonal concave station 13, to rotary bolt 4 transmissions.In a side of rotary bolt 4, sensible positioning screw hole 14 to concave station 13 is set, and in positioning screw hole 14, screws in dog screw 15, to eliminate the diastema between regular hexagon prismatic 11 and the concave station 13.As shown in Figure 3, also be provided with screens 16 and spacing jacking block 17 on the rotary bolt 4.Screens 16 be used for inner washer 6 on card base 18 cooperate transmission, spacing jacking block 17 then is used to touch snap close, to limit the rotational angle of handle 3.
