Embodiment

The present invention will be further described below in conjunction with accompanying drawing.Should be clear, the specific embodiment of the present invention described in the accompanying drawing only for explanation usefulness of the present invention, is not construed as limiting the invention.Protection scope of the present invention is limited by appending claims.

Fig. 1 is the assembling decomposing schematic representation of the multi-purpose combined tool of a kind of exchangeable tool head among the present invention.As shown in Figure 1, the multi-purpose combined tool among the present invention 100 comprises pad 10 and tool heads 20.One end of described pad 10 has assembling slot 101, and described tool heads 20 has plastic assembling end 201, and the shape and size of the shape and size of plastic assembling end 201 and assembling slot 101 adapt; On the wall of described assembling slot 101 and plastic assembling end 201, have at least two pilot holes 30 respectively, cooperate when putting in place described pilot hole to aim at and adopt screw 50 to tighten fixing at plastic assembling end 201 and assembling slot 101.

A plurality of alignment pins 102 are set in the described assembling slot 101, and corresponding a plurality of locating slot 202 is set on plastic assembling end 201, described alignment pin 102 and locating slot 202 coincide when tool heads 20 is inserted pad 10 mutually, thereby play position-limiting action.

The other end that described pad 10 is relative with having assembling slot 101 1 ends preferably has TDT type handgrip 103.Dissolved in the advantage of two T type handgrips and D type handgrip in TTD type handgrip 103 design, when the shovel object, the operator can grasp the D type circle in the middle of the handgrip, and is easy to operate, handy.And when digging, exert oneself backward in the both sides of holding two T handgrips respectively about again can be with the hands, and making cuts the earth becomes easily laborsaving.

Fig. 2 is that the multi-purpose combined tool of exchangeable tool head among Fig. 1 assembles slot from the observable schematic perspective view of an angle.As can be seen from Figure 2, have 4 alignment pins 102 on a wall of described assembling slot 101, corresponding four locating slots coincide when being in place mutually on described locating piece and the described plastic assembling end 201.Certainly, the quantity of described locating piece and locating slot can change, but is at least one.

Fig. 3 is the multi-purpose combined tool of the exchangeable tool head that assembled among Fig. 1.Plastic assembling end 201 insertion assembling slots 101 and cooperation are put in place, adopt screw 50 insertion pilot holes 30 to tighten then and fix a kind of combination tool that just obtains among the present invention, combined tool as shown in Figure 2.When needs are replaced other tool heads, only need screw 50 is unclamped, from pilot hole 30, take out, plastic assembling end 201 is taken out from assembling slot 101, other tool heads that has plastic assembling end that will need then, as but be not limited to the weeding spade, various side's spade, sharp spade, graip, four tooth forks etc. are fixed to according to previously described method in the assembling slot of pad and get final product.

Fig. 4 is the assembling decomposing schematic representation of the multi-purpose combined tool of another exchangeable tool head among the present invention.Combination tool among Fig. 3 is the improvement to combination tool among Fig. 1.Except the structure shown in Fig. 1, combination tool among Fig. 4 also has protecgulum 60 and bonnet 80 at tool heads 20 plastic assembling ends 201 and assembling slot 101 matching parts, described protecgulum 60, bonnet 80, assembling slot 101 walls and the plastic assembling end 201 of tool heads respectively have at least two pilot holes of aiming at mutually 30, the countersunk head Luo hole of pilot hole 30 on protecgulum 60 for presetting, the screw self-locking hole of pilot hole 30 for presetting on the bonnet 80, fastening screw 50 passes described pilot hole 30 and is tightened.This fastening method makes and can not produce because of afterburning displacement when screw is fastening.

The shaped design of described protecgulum 60 and bonnet 80 becomes assembling to make combination tool have wide and anti-skidding shoulder 70 when finishing, and show as Fig. 5, thereby it is comfortable laborsaving that the operator is stepped on when digging.

Fig. 6 is that the multi-purpose combined tool of exchangeable tool head among Fig. 5 is from the observable anti-skidding shoulder schematic perspective view of an angle.The anti-skidding shoulder 70 of combination tool preferably had a plurality of ribs with anti-skidding lines when as shown in Figure 6, assembling was finished.Have the protecgulum 60 and the bonnet 80 preferred employing rubber or the injection moldings of anti-skidding lines rib, but be not limited thereto.

Assembling slot 101 and handle body 10 are when using metal handle, but integral solder.

If use the handle of being made by the plastics of plastics, the plastics that contain the glass fibre composition, carbon fiber-containing or wood materials etc., assembling slot 101 and handle body 10 can be made and separate, and assembling slot 101 and handle body 10 need be connected and fixed during use.Fig. 7 is the multi-purpose combined tool assembling slot 101 and handle body 10 mount schematic diagrames of exchangeable tool head among the present invention.The storehouse 40 of installation is arranged at assembling slot top, the pommel of holding tool head is inserted storehouse 40 is installed, and inserts punching rivet 90 and fixes.

Based on description of the preferred embodiment of the present invention, should be clear, be not limited only to the specific detail set forth in the top specification by the present invention that appending claims limited, what do not break away from aim of the present invention or scope may reach purpose of the present invention equally to many conspicuous changes of the present invention.
