Abstract
The invention provides a telescopic rod fixing device. Two pipes of different diameters are connected in a sleeved mode to form a rod with the adjustable length, a nut is arranged at one end of the thick pipe 3, a screw rod 5 abuts against a conical head 2 form the inside of the thick pipe 3, when the telescopic rod fixing device is used, pressure is applied to the conical head 2 through the screw rod 5, the conical head 2 enables the opening of the thin pipe 1 to expand so that the thin pipe 1 can be tightly attached to the thick pipe 3, and the purpose of fixing the length of the telescopic rod is achieved.
Description
Technical field
The present invention relates to a kind of bar.A kind of telescopic rod fixer specifically.
Background technique
Needing the instrument using various band bar in daily life, is all generally the bar of constant length, has people also once to invent the bar of variable-length.But, make the later bar of elongated degree be difficult to fixing relative position and affect use owing to not finding suitable fixation method.As mop bar just has this type of defect typical.
Summary of the invention
The invention provides a kind of telescopic rod fixer, thin bar and thick bar can be made can to fix relative position in arbitrary length.
The present invention includes thin bar, conehead, thick bar, screw rod composition, the technological scheme adopted is: thick bar is enclosed within thin bar, and conehead withstands on the mouth of pipe of thin bar, and conehead is connected with screw rod.
Beneficial effect of the present invention is: thin bar and thick bar can be made can to fix relative position in arbitrary length.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described that accompanying drawing is structural representation of the present invention.
Fig. 1 is structural representation of the present invention.
Embodiment
Shown in Fig. 1: bar is divided into two-section by the present invention, thick bar 3 is enclosed within thin bar 1, and conehead 2 withstands on the mouth of pipe of thin bar 1, when screw rod 5 applies pressure to conehead 2, conehead 2 forces the mouth of pipe of thin bar 1 to be expanded, thus makes thin bar 1 and thick bar 3 determine relative position, reaches the object of fixing length of telescopic bar.
Claims (1)
1. a telescopic rod fixer, comprises thin bar (1), conehead (2), thick bar (3), screw rod (5) composition.It is characterized in that: thick bar (3) is enclosed within thin bar (1), and conehead (2) withstands on the mouth of pipe of thin bar (1), and conehead (2) is connected with screw rod (5).
