Embodiment

With reference now to accompanying drawing,, in more detail, total weeding instrument shown in (10) is provided, and it is best shown in Fig. 1 a and 1b, also exist and have each end and end at a tape (12) in the eyelet (will more detailed hereinafter discussion), described end is suitable for they are connected to self the shoulder or the hook shape component (68) of extension, the length of this crouch piece that extends downwards then, thus place or be placed in another claw inside of each forked member base once more.

Described weeding instrument (10) comprises handle (16) crouch piece (being shown (18) usually), and in this embodiment, described handle (16) crouch piece has forked member (20) and (22) separately, and locates to close up at base plate (52).These forked members (20), (22) have corresponding folding portion (24) and (26), thereby it provides towards the more fusiform orientation in bifurcated element (18) bottom by parts (28) and (30).

These folding components (24), (26) make the manual operation of this garden instrument catch handle (16) to operate by the user, and nonessential be complete level or parallel alignment substrate with tool positioned, the user can cosily be positioned over the gardens utensil direction of raising, and along with line (12) thus bury in the time of will being pulled through the stems of the weeds of from soil, removing or root to soil, described line (12) is still correctly disposed.

The shoulder that the part (28) of described branch device (18) and (30) have lengthening, for this gardens utensil, described shoulder makes also that it is easy to make and himself enters in the soil easily, and can upset the cover layer of soil necessarily, and this lengthening also provides usually groove shown in (70) among Fig. 1 a or hook structure simultaneously, and in groove or hook structure, line (12) can be supported between two crouch piece (20), (21).

Important application of the present invention is usually the bearing claw member shown in (36), it has the structure that is similar to crouch piece (18) substantially on direction, and comprise recess (34), the arm shape spare of described crouch piece (18), promptly (20) and (22) can be placed in this place, and, can obtain elasticity and connect in this place's supporting.

Because dentation supporting member (36) extends or leaves the contraction up and down of the handle (16) of this gardens utensil (10), can see, because this crouch piece (18) has arm shape spare (20) and (22) that are placed in the corresponding recess of bearing claw (34) separately, the vertical mobile expansion that converts a forked member and another forked member to of this claw-like member perhaps makes closing up of a forked member and another forked member.

By the tapered member of forming by center rod-like element (40) and nut (50) (46), realized that the bearing claw member can be to handle (16) extension and the ability of shrinking, the rotation of tapered member (46) is converted to moving of rod-like element (40), described rod-like element (40) is installed the bolt (50) that remains on appropriate location in the handle (16), makes the rotation (for example in a clockwise direction) of this tapered member (46) will guarantee that bolt component (40) withdraws from or enter the bolt (50) that suitably is fixed in the handle (16).

The bolt component (40) that is formed by turning clockwise of tapered member (46) withdraws from towards nut (50), guarantees to be pressed in downwards on the described bearing claw member (36).

This effect (36) that presses down on described dentation supporting member causes in the forked member (20) of branch device (18) and the corresponding recess (34) that (22) further slip into this bearing claw member, thereby launches with bigger bifurcated.

The expansion of a so this clamp forks (20) and another clamp forks (22) can be tightened to line (22) its tensity that needs.

Because the user can be hooked to line on this crouch piece easily by using eyelet and the shoulder that links to each other and claw (68) and (70), thus can be easily and need not the ability of any additional means or fastening apparatus realization elastic threads (12).

This preferred embodiment in, advantageously (although need not be necessity of the present invention), the claw (68) that the extension (28) of each and (30) comprise top in forked member (20) separately and (22) and the shoulder extension (70) of bottom.

Be understandable that demonstrably, line (12) can be from the bottom drag and drop easily of this crouch piece, and can this forked member (20) of pull-up and (22) each side (28), (30).

Even so, this preferred embodiment in, can change the benefit that line is connected to the physical location of this hand device and mean, in case when this gardens utensil self was deep into the stem that is enough to be pulled through the weeds that will remove or root, it was with little interference soil structure and cover layer.

Can determine, on the claw (68) on the ground fixed position that line (12) is fixed on definitely this gardens utensil, mean that it is a clean single hop line that moves through soil, and in the bottom of this gardens utensil without any block, knot shape thing or other connections.

The best as shown in Figure 4 and Figure 5, bolt component (50) is supported in hole (42), (44) and (54), and aims in guiding element (48) auxiliary maintenance down.

Platform (68) can pack into most flat board (52) and securing member (56) are so tapered member (46) can cosily be placed against handle (16).

In the present embodiment, the circular cylindrical cavity of bolt component (40) withdrawal has and bolt component (40) identical construction (58), thereby prevents nut (50) itself rotation when the user of operation tapered member (46) makes rod component (50) rotation.

Also shown in each figure, have the hole (62) that is fit to hold extension bar, this extension bar can utilize at the inner available screw thread of handle (16) and spiral shell forwards the position to.

This equipment desired advantages is that not only the operator can catch handle (16) cosily to use this garden instrument, what exist in some applications goes down on one's knees or bends to bury garden instrument and carry out the possible difficulty of weeding operation to soil, extension bar (perhaps being called the besom handle similarly) etc. may be connected to garden instrument, makes that it can the standing position operation.

Along the circumferential edges of handle (16) base portion, also comprise the part of other hole (66) as handle (16), it only provides garden instrument to use afterwards and the simple mechanism that can be suspended between the storage life.

The diagonal shear at handle (16) base portion place is meant that in case the claw that the handle utilization is placed in the hole (66) is suspended, global design allows instrument cosily to place with this kind suspension status.

Best as seen as Fig. 4, handle (16) also comprises the Elastic plastic-rubber section bar material around its vertical peripheral edge, generally is shown (60), when the user goes to catch with using appliance, makes that it is comfortable, lastingly and controlled.

Be also shown in as Fig. 4 the best, in handle (16) bottom, have small bending, when the user makes great efforts to catch the gardens utensil and prepares to use it, make that once more it is more comfortable and make things convenient for the user.

Even so, essence of the present invention is unique wedge-shaped arrangement, thereby it can guarantee that the crouch piece expansion makes the line tension.

This can realize by using real rotatable tapered member, the bearing claw member comprises that recess is to lay the arm shape spare of forked member, a forked member be will guarantee to change into to another bifurcated or moving of expansion effect so the bearing claw member moves up and down the tapered member withdrawal that brings, thereby the stretching, extension or the tension of line changed.
