Description

The ball locate mode retractable handle of garden instrument

Technical field

The utility model relates to a kind of garden instrument, and is especially relevant with the ball locate mode retractable handle structure of garden instrument.

Background technology

The Gardener has a lot, such as the saw of the scissors that is used to prune leaf, cutting branch bar, win the pliers of fruit ...Because the cultivated area in gardens varies, trees also have height different, these instruments use for adapting to cultivated area of all sizes and trees, usually handle design is telescopic, so that when small size uses or is used for short trees, implement handle can be shortened, handled easily, and when large tracts of land is used or is used for tall and big trees, implement handle can be extended handled easily.

Traditional garden instrument retractable handle is made up of the pipe fitting 1 ' and the handle 3 ' that are nested with mutually as shown in Figure 1, and the joint of pipe fitting 1 ' is provided with locking piece 2 '.Use when stretching,, but make pipe fitting 1 ' specific elongation or shortening, again locking piece 2 ' is locked, can make the pipe fitting 1 ' location after stretching earlier to locking piece 2 ' release.The retractable handle of this structure, because the position of locking piece 2 ' is away from handle 3 ', during each the adjusting, need hand is moved to locking piece 2 ' release earlier, move to handle 3 ' again and locate to stretch or compress pipe fitting 1 ', then, hand being moved to locking piece 2 ' locks again, mobile so repeatedly hand not only bothers, and, because various garden instruments are all heavier, when a hand moved, the weight of whole garden instrument just all was pressed in another on hand, so, expanding-contracting action is also very required great effort, if telescopic adjustment still can not reach optimum length or need repeatedly regulate the time, also need carry out repeatedly re-adjustments, and is very inconvenient especially.Afterwards, the someone had researched and developed a kind of garden instrument retractable handle as shown in Figure 2, by the pipe fitting 1 that is nested with mutually " and handle 3 " form governor motion 2 " (do not specifically illustrate among the figure, can indicate by arrow among the figure and understand) directly with handle 3 " be connected.Use when stretching, will rotate handle 3 " with release, stretch again or compression pipe fitting 1 ", then, revolution handle 3 " to lock.So regulate operation and compare, because governor motion 2 with above-mentioned traditional structure " with handle 3 " be connected, in the adjustment process, do not need hand at pipe fitting 1 " and handle 3 " between move about, so it is comparatively convenient to operate; But, at rotation handle 3 " time, the weight of whole garden instrument still all is pressed in another on hand, so spinning movement is also very required great effort.

Therefore, all there is the improved structure of needs in existing garden instrument telescoping handle structure, and this studies inventor's base, has this case structure to be born then.

The utility model content

The purpose of this utility model is to provide a kind of ball locate mode retractable handle of garden instrument, and it is flexible easy to operate, laborsaving.

In order to reach above-mentioned purpose, solution of the present utility model is:

The ball locate mode retractable handle of garden instrument, mainly form by pipe fitting that is nested with mutually and handle, offer fluting at outer tube near on the end of handle, button of plant in the fluting, button by between a side of handle and the fluting to establishing a spring, one end of the opposite side of button and pull bar is connected and fixed, the other end at outer tube plugs a sleeve pipe, offer a locating hole on the tube wall of sleeve pipe, spin is contained in this locating hole, the position of corresponding locating hole forms one group of locating slot on the outer wall of interior pipe, pull bar is arranged in the outer tube against the inwall of outer tube, the other end of pull bar stretches between the outer wall of the inwall of outer tube and sleeve pipe and by spring and supports and cover on locating hole, makes spin be in locating hole and the locating slot in the order pipe and outer tube simultaneously and locatees.

Above-mentioned handle extends to the position that outer tube is installed button, and the fluting of corresponding outer tube also forms interspersed groove, and button is plugged in the fluting of the interspersed groove of handle and outer tube.

After adopting said structure, the utility model uses when stretching, only need with thumb gently to handle direction compression spring, pulling button, can drive pull bar moves to the handle direction, the other end of pull bar will be opened locating hole, this moment, spin was able to enter fully in the locating hole by withdrawing from the locating slot, realize release, then, application of force stretching outer tube or compression outer tube loosen thumb, under the effect of spring again to Len req a little, the other end of pull bar covers again on locating hole, spin is in simultaneously makes interior pipe and outer tube location lock in locating hole and the locating slot.

The utility model, does not need hand is moved about between pipe fitting and handle in the adjustment process owing to regulate button near handle, so, flexible easy to operate; And, only need do simple stretching and compressed action during owing to adjusting, so in the adjustment process, the weight of whole garden instrument is pressed in two on hand all the time, so, regulate rapid operation.
