Technical field
The utility model relates to the coupling assembly of a kind of weeder power take-off and working head, and especially a kind of clamping device that adopts belongs to weeder component technology field with the assembly that the power take-off and the working head of weeder clamps fast.
Background technology
The power take-off of existing weeder and the coupling assembly structure of working head are as shown in Figure 1, after in the chuck 20 of mandrel 10 insertion power take-offs 1 one ends of working head 5, be pressed in chuck 20 outer circumference end with chuck nut 30 cover again and be spirally connected with power take-off 1 one end outer walls, when tightening when being spirally connected, chuck nut 30 clamping collets 20 and mandrel 10 can use like this.But need use aid (as spanner) during the installation of above-mentioned draw bail, and not produce relative motion because folder is not tight easily between chuck 20 and the mandrel 10, therefore connect inconvenient.
The utility model content
The purpose of this utility model is: the shortcoming at above existing weeder exists, and propose a kind of weeder and clamp assembly fast, this assembly need not any aid can carry out positive connection easily.
In order to reach above purpose, weeder of the present utility model clamps assembly fast and comprises power take-off, can be plugged in the working head in the jack of power take-off end and can be set in the gripping sleeve of power take-off end; Described power take-off end is shaped on the perforation of at least one and described jack vertical connection, and its periphery wall is shaped at least one circle caulking groove; Be coated with pellet shot from a slingshot in the described perforation, the mandrel end outer peripheral face of described working head is shaped at least one circle groove, is shaped on the inside protuberance of at least one circle in the described gripping sleeve, and described power take-off end periphery wall is set with elastic component; When described power take-off, working head and gripping sleeve are coupled to each other when fiting, one end of described elastic component is against on the step of power take-off end, its other end is against a side of protuberance, the opposite side of described protuberance is against back-up ring one side that is nested in caulking groove, described perforation and groove over against, described pellet shot from a slingshot is resisted against respectively on the internal perisporium of groove walls and protuberance.
During assembling, earlier elastic component is sleeved on the power take-off end, penetrates pellet shot from a slingshot in the perforation, again with hand with the gripping sleeve encapsulation in the power take-off end; This moment, elastic component one end was against on the step of power take-off end, its other end is against a side of protuberance in the gripping sleeve, continue oppositely to move along the power take-off end with the hand propelled gripping sleeve, the deformation of protuberance compressing elastic component, protuberance leaves perforation, back-up ring is nested in the caulking groove 9 of power take-off 1 periphery wall, this moment, the mandrel with working head inserted in the jack of power take-off end, unclamp gripping sleeve then, under the elastic component reaction force, gripping sleeve moves to the power take-off end, and protuberance moves to perforation place and pellet shot from a slingshot is pressed in the groove of working head mandrel end, finishes the clamping assembling between power take-off and the working head.
Obviously, the assembling process that above-mentioned weeder of the present utility model clamps assembly is fast compared existing weeder, rapid and convenient more, and need not any aid; This assembly is simple in structure in addition, connects reliably, and it is good to make assembly process process.

Embodiment
Embodiment one
The weeder of present embodiment clamps assembly fast shown in Fig. 2,3, comprise power take-off 1, working head 5 and gripping sleeve 4, the mandrel of working head 5 is plugged in the jack 7 of power take-off 1 end, and gripping sleeve 4 is set in the end of power take-off 1, and the end of power take-off 1 is shaped on step 13.Be shaped on two circular perforations 8 with jack 7 vertical connections in the end of power take-off 1, be shaped on a circle caulking groove 9, in perforation 8, be coated with pellet shot from a slingshot 3 at the periphery wall of power take-off 1.The mandrel 10 end outer peripheral faces of working head 5 are shaped on a circle groove 11.Be embedded with an inwardly outstanding compacting ring 12 in the gripping sleeve 4.The end periphery of power take-off 1 is set with spring 2.The caulking groove 9 embedded back-up rings 6 that are with.
As shown in Figure 7, the cross section of gripping sleeve 4 is a triangle, and its three angles are arc transition.
During assembling, earlier spring 2 is sleeved on the end of power take-off 1, pellet shot from a slingshot 3 is installed in the perforation 8, with hand gripping sleeve 4 is sleeved on the end of power take-off 1 again; This moment, one end of spring 2 was against on the step 13 of power take-off 1 end, and the other end of spring 2 is against a side of compacting ring 12 in the gripping sleeve 4.Continue oppositely to move (triangle gripping sleeve 4 is beneficial to hand-held and firmly moves) along power take-off 1 end with hand propelled gripping sleeve 4,2 deformation of compacting ring 12 pressuring springs, this moment, compacting ring 12 left perforation 8.Again back-up ring 6 is nested in the caulking groove 9 of power take-off 1 periphery wall, then working head 5 is inserted in the jack of power take-off 1 end.Unclamp gripping sleeve 4 then, under spring 2 reaction forces, gripping sleeve 4 moves to power take-off 1 end, and compacting ring 12 moves to perforation 8 places and pellet shot from a slingshot 3 is pressed in the groove 11 of mandrel 10 ends of working head 5; Bore a hole this moment 8 with groove 11 over against, pellet shot from a slingshot 3 is resisted against respectively on the internal perisporium of groove 11 walls and compacting ring 12, the clamping of finishing between power take-off 1 and the working head 5 is assembled.The present embodiment weeder that has assembled clamps assembly fast, connects between power take-off 1, gripping sleeve 4 and the working head 5 and fits; At this moment, the opposite side of compacting ring 12 is against a side of back-up ring 6, the perforation 8 with groove 11 over against, pellet shot from a slingshot 3 is resisted against respectively on the internal perisporium of groove 11 walls and compacting ring 12.
By above-mentioned assembling process as can be known, the weeder of present embodiment clamps assembly fast and compares existing weeder, assembles rapid and convenient more, and need not any aid; This assembly is simple in structure in addition, connects reliably, and it is good to make assembly process process.
In addition to the implementation, the utility model can also have other embodiments.For example, 1) perforation is one or more, corresponding pellet shot from a slingshot be one or more also be feasible; 2) groove also can be two circle or multi-turns, and respective perforations and pellet shot from a slingshot can be two corresponding row or multiple rows; 3) caulking groove also can be two circle or multi-turns, and corresponding back-up ring can be one or more, can guarantee the fixing reliable and secure of compacting ring like this; 4) compacting ring 12 also can be to be welded in the gripping sleeve, or the inside outstanding step that integral body is made in the gripping sleeve, forms an inside protuberance in a word; 5) spring 2 also can be replaced for body by torsion spring or other elastic component; 6) perforation 8 also can oval or other shape; Or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
