Parts title and serial number in figure:
Bar 1, knob 2, knob core 21, locating piece 22, sleeve 23, axial groove 24, arc groove 25, limiting slot 26, shell 27.
Specific embodiment
Illustrate specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, the Telescopic adjustable control stick in the present embodiment includes bar 1 and the knob 2 for being fixed on boom end.
As shown in Fig. 2, knob 2 includes shell and knob core 21, knob core 21 is cylindrical, and one end is slotting with shell inserting connection
End is filled, the other end is the connecting pin connecting with bar 1.The cylindrical side surface that knob core 21 inserts end is arranged there are two locating piece 22,
Two locating pieces 22 are about 21 axle center of knob core rotational symmetry.
As shown in figure 3, knob shell is made of shell 27 and fixed sleeve 23 inside the shell, sleeve 23 is fixed on shell
In 27, the inner hole of casing 23 constitutes the inserting hole with the inserting connection of knob core inserting end.It is provided on the wall surface of casing 23
Two axial grooves 24, axial groove 24 and the axial line of inserting hole are parallel to each other.Corresponding every axial groove 24 is provided with more arcs
The axial line of shape slot 25, plane and inserting hole where arc groove 25 is mutually perpendicular to.The starting point of arc groove 25 and axial groove
24 connections, the other end are provided with limiting slot 26, and limiting slot 26 is located at the axial direction of arc groove end.Two axial grooves and with
The arc groove of corresponding axial groove connection, limiting slot are about inserting hole axle center rotational symmetry.
As shown in figure 4, knob core inserting end inserting is connected in the inserting hole of knob shell, namely it is inserted into casing
In inner hole, two locating pieces on knob core can slide in corresponding axial groove and arc groove, and by arc groove 25
