Description

A kind of graden machine

Technical field

The utility model belongs to technical field, more particularly, to a kind of graden machine.

Background technique

Graden machine refers to chain saw, edge severing machine, trimmer, GREEB HEDGE MACHINE, brush cutter, grass dressing machine, branches of tall trees machine, Bothridium Machine, mowing Machine, lawn machine etc. for afforestation, gardens construction, park maintenance mechanical equipment.Chinese patent CN205812889U Disclose " a kind of Telescopic garden tool " comprising head, telescopic rod, the first connector sleeve, the second connector sleeve and locking device, Head is socketed in the second connector sleeve.Although can realize a tractor serves several purposes under this kind of structure, and head dismounting is more convenient.But due to Head is socketed in the second connector sleeve, and when dismounting needs to hold head, is needed to be hold by one hand telescopic rod, is hold by one hand machine Plug alignment on head is inserted into the second connector sleeve by head, and mobile head.Due to having blade, motor etc. in head Component, volume is big, and weight is big, very laborious under this kind operation, due to being influenced by head weight, the lesser adult of strength It often not can guarantee plug and be directed at the insertion of the second connector sleeve completely, need to carry out multiple adjustment, time-consuming, and working efficiency is low.

Utility model content

The utility model for overcome the deficiencies in the prior art, provides a kind of gardens that disassembling operations are easy, time saving and energy saving It is mechanical.

To achieve the goals above, the utility model is using following technical scheme: a kind of graden machine, including grab handle, The body of rod and at least head being detachably connected with the body of rod；The body of rod is equipped with connection-peg, and the head is equipped with and this The locking device that connection-peg matches.By being arranged connection-peg on the body of rod in the utility model, locking device setting is existed On head, and then the operation when dismounting head is that the body of rod is inserted into the grafting chamber on head, and then in operation, is grasped Author is to hold the body of rod on the other hand, holds head on the other hand, and the mobile body of rod is inserted into the body of rod in head；Without mobile volume Greatly, the big head of weight can easily realize disassembling operations, time saving and energy saving；And when dismounting head, since head is motionless, may be used also Head against on the ground in the case where realize disassembling operations, it is more laborsaving, can be real strength lesser adult Now operate.

Further, the locking device includes the grafting chamber on the head, opening on grafting chamber side wall Mouth slot and an at least locking member；By the setting of open slot, so that the size of grafting chamber may be configured as being greater than the big of connection-peg It is small, and then in grafting operation, connection-peg is easier to be inserted into grafting chamber, and operation is more easy to be easy；Pass through the lock of locking member Open slot can be tightly eliminated, and then guarantees that grafting cavity wall compresses connection-peg completely under normal connection status, is connected firmly.

Preferably, the locking device further includes the attachment base and locking bed matched with the locking member, the connection There is the gap being connected with the open slot between seat and locking bed；The locking member can be overturn with respect to attachment base；By turning over Turning locking member can realize that locking member is press-connected seat, so that the gap between attachment base and locking bed reduces or disappears Grafting chamber is directly realized by the compression of connection-peg, it is easy to operate, it is easy to implement.

Preferably, the locking member is set as two, two locking members pass through connector respectively and are connected with the attachment base； Since locking member is set as two, and then locking effect is more preferable, after long-term use, when one of locking member loosens When, locking member in addition still can be realized good locking effect, and locking effect is good, and failure rate is low, and maintenance rate is low.

Preferably, the locking member is set as one, which is connected by two connectors with the attachment base；By It is connected in passing through two connectors with attachment base, and then has at two at the locking of locking member and be set as two, is being used for a long time Afterwards, when one of locking member loosens, locking member in addition still can be realized good locking effect, locking effect Good, failure rate is low, and maintenance rate is low.

Further, the locking member at least partly has arcwall face；By the setting of arcwall face, so that locking member is in side To when pulling, can preferably be fitted on head, thus it is more aesthetically pleasing in shape, and space hold is also smaller.

Further, the locking member has connecting pin and upset end, and the attachment base is arranged on the connecting pin, should Connecting pin is equipped with splenium；It is due to being provided with connector, and then when locking member overturning, i.e., controllable to reduce attachment base and locking Spacing between seat；Secondly, by the setting of connector, and then screw or unscrew the i.e. controllable attachment base of connector and locking bed Between gap size so that open slot is adjustable, for comparing traditional locking mode, even if grafting chamber and inserting There is error in size between connector, and the secured connection of the two can be realized by adjusting the size of open slot, and scrappage is low.

Preferably, the body of rod include interior bar, with the outer bar of the interior bar pivot bush unit and for lock interior bar and outer bar it Between relative position locking structure；By the setting of interior outer bar, so that the length of rod piece is adjustable, in the trimming for carrying out certain altitude When, ladder auxiliary that no setting is required can be carried out easily on ground, easy to operate and safer；It is inside and outside when packaging or transport Bar may contract to together, reduce space hold, while packaging material opposite can also be reduced, and save packaging material, more energy-saving ring It protects.

Further, the grab handle is equipped with the interface that can be connected with extraneous power supply；When the electricity of battery is smaller, Or fit on head need high-power power supply when, can by the interface connect external power supply, equipment is powered.

Further, the head is equipped with hand holding handle；When handheld machine, which is beaten the grass or is pruned, to be operated, operator It can grip on grab handle, grip on hand holding handle on the other hand on the other hand, operate more laborsaving.

In conclusion the utility model has the advantage that by being arranged connection-peg on the body of rod, locking device is set It sets on head, guarantees easily realize disassembling operations without the mobile head that volume is big, weight is big, it is time saving and energy saving, even if The lesser adult of strength also can be realized operation.
