Abstract

The utility model relates to a conjunction device for a garden tool head, particularly a garden tool head which can ensure close combination between self and a wooden handle. Primarily, one end of the tool head forms a sleeve barrel with an opening, and the corresponding end of the wooden handle forms a through hole. After the wooden handle is sheathed in the sleeve barrel, a screw rod respectively penetrates through the sleeve barrel, the wooden handle and an arc press sheet arranged outside the sleeve barrel, and then is fastened by a butterfly screw cap. At this time, the arc press sheet is matched to frap the opening of the sleeve barrel to gird the sheathed wooden handle.

Description

Garden tool head combining device

The utility model relates to garden tool set, particularly a kind of garden tool head combining device.

Tradition garden tool such as hoe, rake or circle sled and so on, after using a period of time, its tool heads combining device and wooden handle promptly have loosening anxiety, cause and use inconvenience, even influence safety, with rake shown in Figure 4 80 is example, be whole ground, a kind of farmland or gardening instrument commonly used, it is mainly constructed and comprises rake 80 and the wooden handle 90 that combines with it, and rake 80 1 ends are formed with several harrow nails that is claw-like 81, and the other end has a sleeve 82, for sheathed wooden handle 90, one fixing hole 83 is arranged on the sleeve 82, and wooden handle 90 external diameters are equal to sleeve 82 internal diameters approximately or are bigger, and front end can be whittled into taper, so that insert sleeve 82, squeeze into wooden handle 90 for the combination of guaranteeing the two with the fixing hole 83 of an iron nail 84 on sleeve 82, before not hammering into fully,, further wooden handle 90 is combined with sleeve 82 iron nail 84 bendings.Rake 80 is not attained close and firm with the combination of wooden handle 90, reason is that the combination of the two mainly is to adopt the packing mode, in use for some time, because of wooden handle 90 in the boss compressive deformations such as corner angle of junction summer in the winter cold and heat phenomenon of expanding with heat and contract with cold in addition, cause sleeve 82 loosening, though the two is with iron nail 84 reinforcings, when sleeve 82 takes place to become flexible phenomenon with the junction of wooden handle 90, the effect of iron nail 84 only can stop wooden handle 90 to deviate from sleeve 82, and can't prevent the generation of loosening phenomenon.The iron nail 84 that bends on the sleeve 82 protrudes in the surface, causes grass roots, foreign material to twine easily and impedes.Combining between general garden tool and wooden handle, all with above-mentioned similar approach combination, thus the ubiquity same problem, thereby further improved necessity is arranged.

The purpose of this utility model is to provide a kind of garden tool head combining device of guaranteeing that tool heads and wooden handle are combined closely,

Realize the garden tool head combining device of the present utility model of above-mentioned purpose, it mainly is to be formed with sleeve at the first end of instrument, for sheathed wooden handle, it is characterized in that:

The root edge place of sleeve is formed with the opening of a slit-shaped, and sleeve is provided with an arc compressing tablet outward in addition;

One screw rod runs through sleeve, wooden handle and arc compressing tablet successively, gives fasteningly again with a butterfly nut, can dwindle opening and sleeve diameter by this, and tighten the wooden handle that is inserted in.

In addition, the side outer wall in addition of sleeve is provided with reinforced sheet, and reinforced sheet is formed with corresponding perforation respectively with the sleeve corresponding position, passes for the screw rod correspondence; The perforation peritreme of sleeve is rectangular shape, and screw rod is in its also holding section of rectangular shape below cap portion.

Can find out that by above technical scheme garden tool head combining device of the present utility model has possessed following advantage at least textural:

1. can keep tool heads and wooden handle strong bonded for a long time: because the sleeve openings of tool heads combining device can be regulated, therefore, when tool heads is used for a long time and expanded with heat and contract with cold phenomenon and occur in the junction can keeping fit tight by the adjusting of butterfly nut when loosening.

2. structural strength is good: the tool heads combining device has reinforced sheet and arc compressing tablet respectively at the sleeve opposite end, can improve the structural strength of junction relatively, to increase the service life.

3. have an even surface: screw rod of the present utility model is after penetrating sleeve, and its cap portion will be embedded in the perforation of reinforced sheet, makes sleeve surface keep smooth, is unlikelyly impeded winding by weeds root, cord.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing:

Brief Description Of Drawings:

Fig. 1 is an exploded view of the present utility model.

Fig. 2 is the utility model tool heads and main cutaway view after wooden handle combines.

Fig. 3 is the utility model tool heads and sectional view after wooden handle combines.

Fig. 4 is the outside drawing of traditional rake.

Combined structure of the present utility model is applicable to any garden tool that must combine with wooden handle, for ease of explanation still is that example discloses concrete technology contents of the present utility model with the rake, see also shown in Figure 1, mainly form by a tool heads 10 and wooden handle 20, tool heads 10 1 ends are formed with several harrow nails that is claw-like 11, the other end has a sleeve 12, and for sleeve wooden handle 20, characteristic of the present utility model is:

The root edge place of sleeve 12 is formed with the opening 13 of a slit-shaped, and the big young pathbreaker in opening 13 gaps directly influences the internal diameter of sleeve 12, and the root edge place of sleeve 12 is provided with a perforation 14 in addition, and perforation 14 is passed through by opening 13;

Sleeve 12 is provided with reinforced sheet 15 on the side outer wall in addition relative opening 13, reinforced sheet 15 cooperates sleeve 12 outer walls and curved shape, and be welded on sleeve 12 outer walls, reinforced sheet 15 is formed with corresponding perforation 150,120 respectively with sleeve 12, pass for a screw rod 16, the rectangular shape of perforation 120 peritremes of its middle sleeve 12, screw rod 16 also becomes rectangular-shaped holding section 160 (seeing also shown in Figure 2) at it below the cap portion, can use the perforation 120 that is fastened on sleeve 12, unlikelyly freely rotate so that make screw rod 16 penetrate the back fully.

Be provided with an arc compressing tablet 17 in addition outside the sleeve 12, perforation 170 is also arranged on the arc compressing tablet 17, can pass, give fastening with a butterfly nut 18 subsequently for screw rod 16 correspondences.

The front end appropriate location of wooden handle 20 is formed with a radial direction through hole 21, and through hole 21 can be screw rod 16 simultaneously and runs through just corresponding to the perforation on the sleeve 12 120,14.

When tool heads 10 is used in combination with wooden handle 20, see also Fig. 2, shown in 3, wooden handle 20 inserts sleeve 12, make perforation 21,150,120,14 aim at mutually, pass successively with screw rod 16 subsequently, after screw rod 16 passes arc compressing tablet 17, the holding section 160 of its upper end also snaps in the perforation 120 of sleeve 12 simultaneously, no longer rotates, and is threaded onto on the screw rod 16 with butterfly nut 18 again, screw arc compressing tablet 17, arc compressing tablet 17 is because of pressurized clamp sleeve 12, and then makes opening 13 dwindle the gap, shrinkage sleeve 12 and tighten wooden handle 20, therefore, wooden handle 20 can be incorporated in the sleeve 12 securely.
