Abstract

The utility model relates to a telescopic handle of a tool. The utility model is composed of an outer tube, an inner tube and a locking device, wherein the inner tube which is provided with a through hole slides in the outer tube; the locking device is arranged between the inner and the outer tubes; the locking device is connected with a lock head with a spring by a lock sheet which is installed in a connecting sleeve; the lock sheet is formed in the method that the lock sheet is matched with a press-button cover which is installed on the connecting sleeve; the press-button cover is composed of a press button and a cover plate. Provided the press button is pressed by hand, the lock sheet is driven by the press button to lift the lock head away from the through hole on the inner tube, the locking device can be opened, the length of the locking device is adjusted to the needed position, thereby, the utility model is convenient in use and operate; the hand is disengaged, the lock sheet rotates upwards, the lock head resets and is again inserted into a lock hole on the inner tube, thereby, the utility model is firmly and reliably locked and fixed, and the utility model which can not slip when used for a long time is durable; in addition, the locking device is fully arranged in the connecting sleeve, thereby, the volume is small, the structure is simple and the utility model is free from external influences.

Description

The telescopic tool handle

Technical field

The utility model relates to a kind of pad, particularly a kind of adjustable in length, can be with the mophead of various different structures, wipe the matching used telescopic tool handles of instrument such as window brush, garden tool.

Background technology

Existing commercially available telescopic pad has the stopping type of employing, multiple different retaining mechanism such as rotary, uses inconveniently, and the time is with long back parts depreciation, and lock not tightly, easily skid.

The patent No. 200420027349.6 " telescoping handle of garden tool " provides a kind of locking mechanism different telescoping handles, but the use of the retaining mechanism of this structure is not firm, and strength is used a little louder slightly, and steel ball will eject the purpose that does not reach locking.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of telescopic tool handle is provided, with the supporting use of various tool, adjustable length, satisfies user's different demands, and easy for operation, locking, fixed can not be skidded, and is durable in use.

The technical scheme in the invention for solving the above technical problem is: the telescopic tool handle, constituted by outer tube, the locking device that has between through hole and interior pipe that in outer tube, slides and inner and outer pipe, described locking device is connected with the tapered end that has spring by the locking plate that is installed in the adapter sleeve, locking plate also be installed in adapter sleeve on button cover cooperate constitute.

Compared with prior art, advantage of the present utility model is: this telescopic tool handle, as long as press button with hand, button drives locking plate and tapered end is mentioned the lockhole that leaves on the interior pipe downwards, just can open locking device, pipe in moving again, release handle long and short uses, easy to operate.Hand is decontroled the button locking plate and is upwards resetted, and in the lockhole in tapered end moves down and inserts on the pipe, all can not pull with great strength very, so locking, fixed, the time can not skid with length yet, and is durable in use.This locking device is installed in the adapter sleeve in addition, is not subjected to ectocine, and what spring adopted is the turriform spring, and the compression back becomes a plane, and locking plate also be a laminated structure, and institute takes up space few, compact conformation, simply, volume is little.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

There is the box 11 of bottom surface band through hole on adapter sleeve 4 one surfaces, and are fluted on the two side of box, and the lower limb in the middle of the two side has two open recess.

Button cover is made up of button 5 and cover plate 8 two parts, on the edge of button two sides flange is arranged, and an annulus 6 of projection is arranged on the inwall, and there is flange at edge, cover plate 8 two sides.

Locking plate 7 is that the bent sheet of large and small circular arc opening constitutes by two ends, on 10 of the locking plate 7 roundlet arc openings insertion tapered ends, tapered end 10 inserts in the through hole at 11 ends of box, that the tapered end top is put into down is little, go up big turriform spring 9, the edge, bending place extends two projections 13 in the middle of the locking plate, two projections 13 are embedded in two open recess of box lower limb, cover button 5, cover plate 8 and be connected on box 11 surfaces of adapter sleeve 4 with the groove fit on flange on it and box 11 sidewalls respectively, and locking plate 7 great circle arc openends cooperate with annulus 6 on button 5 inwalls.The adapter sleeve 4 that assembles is enclosed within outside the interior pipe 3, outer tube 1 of band chock plug 2.

Need only during use and press button 5 downwards with hand, and the locking plate 7 that drive and button link together rotates, locking plate is on the fulcrum with projection 13, the following rotation, the orthodrome openend rotates, then roundlet arc openend upwards rotates, and the tapered end 10 that drive links into an integrated entity with it also up rotates, to pull out the lockhole 12 of tapered end 10 from interior pipe 3, pipe 3 in breaking away from, in the pipe unobstructed just can more than, move down and regulate length, satisfy user's requirement, mix up back release button 5, the upwards rotation of its orthodrome openend that resets of no external force effect locking plate 7, then roundlet arc openend just rotates, tapered end 10 is got back in the lockhole 12 of interior pipe 3, with interior pipe 3 again, outer tube 1 is locked together.

Claims
