Abstract
The invention discloses a firm-connected pull rod which comprises an outer pipe and an inner pipe sliding fit with the outer pipe. A containing space is positioned in the outer pipe, and the inner pipe is positioned in the containing space. Conical degrees matched with each other are formed on an outer surface of the outer pipe and an inner surface of the inner pipe containing space. Due to the fact that conical degrees matched with each other are formed on the outer surface of the outer pipe and the inner surface of the inner pipe containing space, the firm-connected pull rod does not swing and is convenient to use.
Description
Technical field
The present invention relates to a kind of pull bar that is connected firmly.
Background technique
At present, the common pull bar that is connected firmly generally comprises outer tube, and and outer sliding tube inner tube movingly, being provided with containing space in described outer tube, described inner tube is arranged in containing space.Yet, because the outer surface of outer tube and the internal surface of inner tube containing space are all that straight line contacts, can occur when in use rocking, use inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly can not rock, the pull bar that is connected firmly easy to use.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: comprise outer tube, and and outer sliding tube inner tube movingly, being provided with containing space in described outer tube, described inner tube is arranged in containing space; The internal surface of the outer surface of described outer tube and inner tube containing space is provided with the tapering that cooperatively interacts.
The pull bar that is connected firmly of the present invention, because the outer surface of outer tube and the internal surface of inner tube containing space are provided with the tapering that cooperatively interacts, in use, and the situation that can not occur rocking, easy to use.
Description of drawings
Fig. 1 is the schematic diagram of the pull bar that is connected firmly of the present invention.
Embodiment
In the present embodiment, with reference to shown in Figure 1, the pull bar that this is connected firmly comprises outer tube 1, reaches the inner tube 2 that is slidably matched with outer tube 1, is provided with containing space 10 in described outer tube 1, and described inner tube 2 is arranged in containing space 10; The internal surface of the outer surface of described outer tube 1 and inner tube containing space 10 is provided with the taper angles A that cooperatively interacts.In use, the situation that can not occur rocking, easy to use.
The pull bar that is connected firmly of the present invention, the end that is connected with inner tube due to described outer tube is provided with the tapering that cooperatively interacts, in use, and the situation that can not occur rocking, easy to use.
Below the present invention is described in detail, the above only is the present invention's preferred embodiment, when not limiting the scope of the present invention, namely allly does impartial change and modify according to the application's scope, all should still belong in covering scope of the present invention.
