Include and be positioned at rotary handle, the lower section being located at rotary handle and the rotation being connected with the second piston connected outside cylinder
Bar, described swingle scalability embeds and connects in cylinder.
As optimal technical scheme, in order to intuitively show the distance that telescoping rod elongates or shortens, side
Just operating, improve flexible degree of accuracy simultaneously, described piston rod is provided with graduation apparatus.
As optimal technical scheme, in order to make telescoping rod easy and simple to handle, ensure telescoping rod even simultaneously
The tight steadiness connect, described swingle is threaded connection with even cylinder.
As optimal technical scheme, in order to the company's of making cylinder is easy to connect with rod member body, ensure that it is even simultaneously
Connecing tight and steadiness, described rod member body is connected with even cylinder by the connector on its end, and connects
Part is threaded connection with even cylinder.
Compared with prior art, this utility model has the advantages that
1, the relative length of rod member body and piston rod is changed by hydraulic way, it is achieved telescoping rod
Elongate or shorten, change traditional nested structure, it is not necessary to release original pressure and just can freely adjust
The length of whole telescoping rod, easy and simple to handle, range is wide, and practicality is good.
2, piston rod is provided with graduation apparatus, can intuitively show the distance that telescoping rod elongates or shortens,
Convenient operation and practicality, improve flexible degree of accuracy simultaneously.
3, swingle is threaded connection with even cylinder, and the length being realized telescoping rod by rotation is adjusted
Whole, easy and simple to handle and be completely embedded firm；Arrange and the connector that even cylinder is threaded connection, convenient
Even cylinder and the assembling of rod member body, guarantee to connect fastening simultaneously.

Detailed description of the invention
This utility model one specific embodiment, a kind of telescoping rod, bag are proposed as illustrated in fig. 1 and 2
Include the rod member body 1 of hollow, in described rod member body 1, be sequentially provided with hydraulic cylinder from top along end
2, first piston 3, piston rod 4, this external and extension of rod member is extended in described piston rod 4 one end
The diameter going out rod member body 1 outer piston bar 4 is less than the diameter being positioned at part body 1 inner piston rod 4, institute
State rod member body 1 near i.e. top, one end of hydraulic cylinder 2 connect have be perpendicular to rod member body 1 arrange
Even cylinder 5, is provided with the second piston 6 being connected with hydraulic cylinder 2, described second piston 6 in described even cylinder 5
The revolving part 7 being arranged over T-shaped shape, this revolving part 7 includes being positioned at the rotation hands outside even cylinder 1
Handle 7-1, it is located at the swingle 7-2 being connected below rotary handle 7-1 and with the second piston 6, described rotation
Bull stick 7-2 scalability embeds and connects in cylinder 5, and the top of described rod member body 1 is provided with cylinder cap.
Extend the piston rod 4 outside rod member body 1 be provided with graduation apparatus 4-1, graduation apparatus 4-1 can be straight
See the distance that display telescoping rod elongates or shortens, carry out reasonable operation in conjunction with graduation apparatus 4-1, easy
Practicality, improves flexible degree of accuracy simultaneously.
Described swingle 7-2 leads to 5 with even cylinder threadeds excessively, i.e. swingle 7-2 outer surface upper end sets
Having external screw thread, as shown in Figure 4, even the internal relevant position of cylinder 5 arranges female thread, as it is shown in figure 5,
Only need to hold rotary handle 7-1 to rotate, so that it may change swingle 7-2 and embed the length of even cylinder 5, behaviour
Making simplicity, threaded guarantee swingle 7-2 is fastenedly connected with even cylinder.
Described rod member body 1 is connected with even cylinder 5 by the connector 1-1 on its end, and connector 1-1
It is threaded connection with even cylinder 5, is i.e. provided with external screw thread on connector 1-1 outer surface, such as Fig. 3 institute
Show, then in even cylinder 5 inner surface corresponding position, female thread is set, as it is shown in figure 5, threaded engagement makes
Even cylinder 5 is easy to assembly with rod member body 1, processing technique is simple, ensures that it is completely embedded and surely simultaneously
Solidity.
When this utility model uses: this utility model is connected on equipment or the corresponding position of instrument, if
The length of telescoping rod need elongation time, hold rotary handle 7-1 and be rotated down, the second piston 6 to
Lower squeezed fluid cylinder pressure 2, thus hydraulic cylinder 2 promotes promotion first piston 3 forward, and then first piston 3
Piston rod 4 is promoted to extend outside rod member body 1；If the length of telescoping rod needs to shorten, hold
Rotary handle 7-1 rotates up, and the second piston 6 discharges hydraulic cylinder 2, thus hydraulic cylinder 2 discharges
One piston 3 is moved rearwards by, and then shortening piston rod 4 extends the length outside rod member body 1；No matter
Elongation or shortening, be all to be realized by the relative length of change telescoping rod 1 with piston rod.
Certainly, the most simply combine accompanying drawing this utility model preferred embodiment has been made in detail
Describe, not limit practical range of the present utility model with this, all according to principle of the present utility model, structure
Make and structure is made equivalence change, all should be covered by protection domain of the present utility model.
