Abstract

The utility model provides a shank combining and fixing structure for a garden tool. An eccentric swinging rod device is composed of a fixing positioning rod which is provided with an eccentric shaft hole, a swinging positioning rod which is provided with an opposite eccentric group hole and a bolt rod, wherein, the fixing positioning rod is sheathed in a handle hole of a tool body and is positioned and fixed, a bolt rod is penetrated through an eccentric shaft hole and an eccentric group hole as integration for connecting the fixing positioning rod and the swinging positioning rod, wherein, a swinging shaft of the bolt rod is correspondingly pivoted and penetrated in the eccentric shaft hole, the head of the bolt rod is positioned on the side of the swing shaft or the eccentric shaft hole, and the end of the bolt rod is connected with the eccentric group hold in a fixed, combined and positioning mold. A sleeve hole of a hank is slightly larger than that of the eccentric swing rod device, but the sleeve hole can not exceed the twice of an eccentric distance, the utility model can reach the practical purposes of convenient assembly and disassembly, convenient replacement and steady structure, and the utility model is not easy to drop.

Description

Garden tool set handle group fixing structure

The utility model provides a kind of garden tool set handle group fixing structure, and mainly by the maintenance bar of a tool eccentric pivot hole, one has a bar that revolves in eccentric relatively group hole, cooperates a tightening latch structure to form the specific combination structural design of eccentric swing arm device for it.

Press, the handle of tradition garden tool set directly extends setting from tool body usually, it is very not enough that right its manufactured the comfortableness that is difficult for and grips, cause user's hand to injure improperly again easily, so all handle is changed into assembled or setting separately, general all extension one is end on tool body, and the urgent plug sleeve of handle that will preset moulding again places on the end, and so it still has following shortcoming situation generation when reality is used:

1. the urgent plug sleeve of handle is put extremely inconveniently, and needs slowly the cover group otherwise damaged easily, and the handle running-on is with respect to holding size if excessive being easy to gets loose in addition, too smallly then can't be nested with assembling.

2。The tradition handle is a fixed group of cover, and the user all can not change suitable handle voluntarily, and makes the handle form lack various conversion too merely, and operating habit, the gesture with each user has nothing in common with each other especially.

So, how to develop a kind of garden tool set handle group fixing structure that has more practicality and convenience, be the novel product that the consumer looks forward to, also be the target of relevant dealer's concerted effort research and development.

Given this, originally it is engaged in various Products Development and design experiences to the creator for many years, at above-mentioned target, and the scrupulous assessment of design in detail, and several times study improvement, get the utility model of a true tool practicality eventually.

Promptly, main purpose of the present utility model provides a kind of garden tool set handle group fixing structure, it is by the maintenance bar of a tool eccentric pivot hole, one has a bar that revolves in eccentric relatively group hole, cooperate a tightening latch structure to form the specific combination structural design of eccentric swing arm device, must impel it to reach the practical purpose that convenient group is unloaded replacing, the firm difficult drop-off of structure.

The purpose of this utility model is reached by following characteristics: its end at tool body is provided with the handle mouth, after organizing a solid eccentric swing arm device on it, cover group one has the handle of running-on again, the handle turn can be located, be primarily characterized in that: this off-centre swing arm device comprises that one has the maintenance bar of eccentric pivot hole, one has a bar that revolves in eccentric relatively group hole, reach one and have head end, revolve the tightening latch of axle, the maintenance bar is nested with in the handle mouth of tool body, and in addition the location group is solid, and tightening latch to be one wear group eccentric pivot hole and eccentric group hole, to link the maintenance bar and to revolve a bar, wherein the corresponding pivot of axle that revolves of tightening latch is through in the eccentric pivot hole, and the tightening latch head end is positioned at and revolves axle or this side of eccentric pivot hole, terminal and the eccentric group Kong Chenggu of tightening latch group combines the location again, and the running-on of handle need be slightly larger than eccentric swing arm device in addition, but must not surpass the twice of its eccentric throw.

Particular design by the eccentric swing arm device 20 of the utility model, must make handle 14 convenient with the assembling of tool body 11, and the user must pick out at random suitable own use habit, the handle 14 surface undulation facings of mode, running-on 13 with handle 14 is placed on the eccentric swing arm device 20 of tool body 11 terminal handle mouths 12 easily, the relative oppositely turn of engagement tool body 11 and handle 14, what must make that running-on 13 drives eccentric rod devices 20 revolves a bar 24, is the relative turn of eccentric shaft by revolving a bar 24 with tightening latch 27 with maintenance bar 22, increase the gap face of its appearance gradually, stay in the running-on 13, reach tool body 11 and borrow eccentric swing arm device 20 turn integrated positioning easily with handle 14, and firm difficult drop-off of structure and the convenient practical purpose of unloading replacing of organizing.

Further understand and understanding for having, cooperate following diagram to be described in detail as follows now the purpose of this utility model, feature and effect:

Fig. 1: be three-dimensional combination figure of the present utility model.

Fig. 2: be three-dimensional exploded view of the present utility model.

Fig. 3: be vertical assembled sectional view of the present utility model.

Fig. 4: be horizontal assembled sectional view of the present utility model.

At first, please consult Fig. 1 earlier, shown in 2, the utility model provides a kind of garden tool set handle group fixing structure, its end at tool body 11 is established and is handle mouth 12, after organizing a solid eccentric swing arm device 20 on it, cover group one has the handle 14 of running-on 13 again, handle 14 turns can be organized set the position, it is characterized in that: this off-centre swing arm device 20 comprises that one has the maintenance bar 22 of eccentric pivot hole 21, one have a relatively eccentric group hole 23 revolve a bar 24, reach one and have head end 25, revolve the tightening latch 27 of axle 26, make maintenance bar 22 be placed on the handle mouth 12 interior (as shown in Figure 3) of tool body 11, and in addition the location group is solid, and tightening latch 27 one are worn group eccentric pivot hole 21 and eccentric group hole 23, to link maintenance bar 22 and to revolve a bar 24, wherein the axle 26 corresponding pivots that revolve of tightening latch 27 are through in the eccentric pivot hole 21, and tightening latch 27 head ends 25 are positioned at and revolve axle 26 or eccentric pivot hole 21 these sides, terminal and the eccentric holes 23 of organizing of tightening latch 27 are solid group and combine the location again, the running-on 13 of (as shown in Figure 4) handle 14 need be slightly larger than eccentric swing arm device 20 in addition, but the twice that must not surpass its eccentric throw a must be impelled it to reach convenient group and unload replacing, the practical purpose of the firm difficult drop-off of structure.

Revolving a bar 24 surfaces the knurling embossing must being set of wherein eccentric swing arm device 20 cooperates handle 14 running-ons 13 inner faces that friction line face also is set, and must make its turn winding really firm more, and handle 14 surfaces must be provided with the various fluctuating facing that is easy to grip.

The figure number explanation: a bar 24 head ends 25 spin axiss 26 tightening latches 27 eccentric throw a are revolved in tool body 11 handle mouths 12 running-ons 13 handles 14 eccentric swing arm device 20 eccentric pivot holes 21 maintenance bars 22 eccentric group holes 23
