Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model is made up of flexible rod etc., described flexible rod is made up of the first pole 11 and the second pole 12, described first pole 11 is overlapped in access second pole 12, guide sleeve 13 is embedded with at the socket place of described second pole 12, in the form of a ring, described first pole 11 is fed through guide sleeve 13 and stretches in the second pole 12 described guide sleeve 13; Described first pole 11 is provided with multiple fixed hole vertically, described second pole 12 is provided with regulator, described regulator comprises the rotatable handle 2 and connecting sleeve 3 made by plastic material, described rotatable handle 2 is in T-shape structure, the middle part of described rotatable handle 2 is axially arranged with first step through hole 21 along the vertical section of T-shape structure, the outside of described connecting sleeve 3 is provided with circular step structure, in one end cover access first step through hole 21 of this connecting sleeve 3, this rotatable handle 2 vertically abuts with the corresponding end face of circular step structure the lower end surface of section.
As shown in Figure 3 and Figure 4, the outer side surface stretching into first step through hole 21 one end at described connecting sleeve 3 is arranged with two balls 31, on the inwall of described first step through hole 21, symmetry is embedded with the described ball of two sections of screw type chutes 32, two 31 and is slidably connected with the spirality chute 32 of corresponding position; The inwall of described first step through hole 21 is also provided with one section of arc notch, and the outer side surface that described connecting sleeve 3 stretches into first step through hole 21 one end is also provided with one section of block 33 vertically, and described block 33 is slidably matched in arc notch.
As depicted in figs. 1 and 2, described connecting sleeve 3 is located in the side of the second pole 12, makes the fixed hole of corresponding position on fixing rod 4 and the first pole 11 wear fixing; Second step through hole 22 is provided with vertically at the middle part of described connecting sleeve 3, fixing rod 4 is provided with in described second step through hole 22, described fixing rod 4 is the little step column structure in large one end, one end, the miner diameter end of this fixing rod 4 is arranged with spring 5, the end face of described fixing rod 4 miner diameter end abuts with the step end face of second step through hole 22, and the end face of bigger diameter end abuts with the step surface of fixing rod 4 step column structure; The end face that described fixing rod 4 stretches into second step through hole 22 is provided with tapped hole 41, bolt 42 is bolted with in described tapped hole 41, described first step through hole 21 is the step hole structure of big at both ends and small in middle, described connecting sleeve 3 overlaps one end of access first step through hole 21, and described bolt 42 wears from the other end of first step through hole 21 and crosses and be spirally connected fixing with tapped hole 41.
Using method of the present utility model is as follows:
As shown in Fig. 1 to Fig. 4, described flexible rod is made up of the first pole 11 and the second pole 12, described first pole 11 is overlapped in access second pole 12, guide sleeve 13 is embedded with at the socket place of described second pole 12, described guide sleeve 13 in the form of a ring, described first pole 11 is fed through guide sleeve 13 and stretches in the second pole 12, second pole 12 is provided with the regulator of rotatable handle 2 and connecting sleeve 3, fixing rod 4 in connecting sleeve 3 stretches in the fixed hole of corresponding position on the first pole 11, so just secures the length of the first pole 11 and the second pole 12.
When regulating height, twisting rotatable handle 2, ball 31 is along the leading role lower slider of spirality chute 32, and rotatable handle 2 is moved laterally, bolt 42 is extracted out in fixed hole with fixing rod 4, under the position-limiting action of arc notch, the distance that block 33 rotates at arc notch is just in time consistent with the displacement distance of ball 31 in spirality chute 32; Now, the step surface of fixing rod 4 presses spring 5, then the position of the first pole 11 is adjusted, after adjusting, hand unclamps rotatable handle, and under the effect of spring 5 elastic force, spring 5 promotes fixing rod 4 travelling backwards fast, fixing rod 4 extend in the corresponding fixed hole of adjusted position postpone, realizes stationary positioned.
Fixed hole because of position location is in the inner side of the second pole 12, can't see particular location, finely tune again after can only adjusting to the height of needs, and now, fixing rod 4 bigger diameter end of travelling backwards also may abut the outer side surface of the first pole 11, now, first pole 11 can be horizontally rotated or under above-below direction moves at left and right directions, make the bigger diameter end of fixing rod 4 can aim at the fixed hole of corresponding position, in this process, because guide sleeve 13 can not to make with the Spielpassung of the first pole 11 to coordinate change of error excessive between each parts in adjustment, the active force adding upper spring 5 is larger, fixing rod 4 just can stationary positioned fast once aligning fixed hole.
In addition, because rotatable handle 2 and connecting sleeve 3 all adopt plastic material to make, the resistance of frictional interference is less, and the borrow that fixing rod 4 and fixed hole are in course of adjustment adjusts lighter, adding plastic material uses upper the allowing property embodied relatively good, regulates more laborsaving.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
