Abstract

A bidirectionally-drawable handle bar comprises a bidirectional coil spring assembly, a first tube, a second tube, a third tube, a first tube handle and a second tube handle. A bidirectional coil spring is fixed in the second tube handle, a descending coil spring connecting end is fixed at the inner bottom of the first tube, an ascending coil spring is fixed at the inner top of the third tube, the first tube handle sleeves the second tube, the second tube handle and the second tube sleeve the third tube, and a connecting bolt is arranged at the third tube end tip. The bidirectionally-drawable handle bar has the advantages that the bidirectionally-drawable handle bar is ingenious in structure, reasonable in design, convenient to use and carry and capable of meeting the use requirements of users on sufficient use length and small enough size in storage, thereby being of practical value and great in market demands.

Description

Biaxial tension handle stem

Technical field

A kind of biaxial tension handle stem.

Background technology

Stretchable handle stem is at keister, and the portable instrument such as similar tripod has and uses widely, has convenient raw Live, improve efficiency, the feature such as both artistic and practical, by the extensive welcome of people.

Although stretchable handle stem in the past has providing amenities for the people, improves efficiency, the feature such as both artistic and practical, but, because It is one direction stretching, cannot take into account in terms of tensile elongation and original state volume, it is impossible to meet length foot when user uses Enough long, the high efficiency that during preservation, volume is sufficiently small uses requirement.

Summary of the invention

It is an object of the invention to the design by biaxial tension handle stem so that it is before not only having, unidirectional handle stem is convenient Life, improve efficiency, the feature such as both artistic and practical, moreover it is possible to meeting length long enough when user uses, during preservation, volume is sufficiently small High efficiency use requirement.

The present invention is made up of two-way wind spring assembly, No. 1 pipe, No. 2 pipes, No. 3 pipes, No. 1 pipe handle and No. 2 pipe handles, two-way Wind spring is fixed in No. 2 pipe handles, and descending wind spring connects end and is fixed on the bottom inside a pipe, and up wind spring is fixed on No. three Top inside pipe, No. 1 pipe handle sleeve is connected on No. 2 pipes, and No. 3 pipe boxes are contained in No. 2 pipe handles and No. 2 pipes, No. three pipe ends It is provided with connecting bolt.

Two-way wind spring assembly is made up of rigid connector and two-way wind spring, and rigid connector is made up of left and right connector, even Wind spring sealed cabin, the outlet of upper wind spring, the outlet of lower wind spring and upper wind spring export orientation connecting platform it is provided with in junctor；Two-way wind spring Being arranged in wind spring sealed cabin by enwinding spring axis, upper wind spring is drawn from the outlet of upper wind spring, by guiding connecting platform and No. three pipes Connecting, lower wind spring is drawn from the outlet of lower wind spring, connects end by lower wind spring and is fixed on the bottom inside a pipe；Left and right connector After fastening, with front and back connecting, post is fixing to be connected.

When using the present invention, on the connecting bolt of No. three pipe ends, first connect the apparatus needing to use, when needing, both hands Hold No. 1 pipe handle and No. 2 pipe handles, stretch to both direction simultaneously, No. 1 pipe pull-out, No. 2 pipes downwards that two-way wind spring connects The exposed one section of application length out forming handle stem；No. 3 pipes are under the top stretch of the up wind spring of two-way wind spring promotes, to extension Go out, form another section of application length of handle stem.Now, by clamping pin-and-hole, locking extended state of the present invention can use.No Used time, it is only necessary to unclamp clamping pin, No. 1 pipe and No. 3 pipes will automatically reset Guan Bi under the effect of two-way spring coiling resetting elastic force.

Present configuration is exquisite, reasonable in design, is convenient to use and carry, can meet length long enough when user uses, and protects The high efficiency that when depositing, volume is sufficiently small uses requirement, has practical practical value and the huge market demand.

Accompanying drawing explanation

Accompanying drawing 1 is the structural representation of the present invention, is also specification digest figure；Fig. 2 is closure state of the present invention signal Figure；Fig. 3 is two-way wind spring assembly structure schematic diagram.In figure, each label is respectively: (1) No. 1 pipe handle, (2) No. 1 pipes, (3) No. 2 Pipe, (4) No. 2 pipe handles, (5) No. 3 pipes, (6) two-way wind spring, (7) right connector, (8) left connector, wind spring outlet under (9), (10) upper wind spring outlet, (11) connect post afterwards, (12) front connection post, and (13) fix screw, and under (14), wind spring connects end, and (15) connect Connect screw, (16) connecting bolt, (17) fixed bin.
