Big figure.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Detailed description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole implementation
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of the utility model protection.
With reference to shown in Fig. 1-3, the derrick crane being easily installed, including large arm, it is many that large arm includes that head and the tail are connected
Individual linking arm 100, two adjacent heads of linking arm 100 support afterbody, and the head lower end of linking arm 100 has protruded outward multiple
One bayonet lock 110, the afterbody lower end of linking arm 100 is concaved with the groove 120 for coordinating multiple first bayonet locks 110, the tail of linking arm 100
Portion upper end has protruded outward the first plate body 130 and the second plate body 140, and the first plate body 130 is relative about 140 with the second plate body to be set
Put, the first plate body 130 offers mutual corresponding first through hole 150, the first plate body 130 and second respectively with the second plate body 140
A grasping part 160 is formed between plate body 140, the head of linking arm 100 protrudes outward the 3rd plate for coordinating grasping part 160
Body 170, the 3rd plate body 170 offers the second through hole of correspondence first through hole 150, in addition to the second bayonet lock 190, the second bayonet lock
190 correspond to the through hole of first through hole 150 and second, and the bottom of the second plate body 140 is provided with a stage portion 200, the tail of the second bayonet lock 190
End is held on stage portion 200.
By the first bayonet lock and groove, the second bayonet lock docks with through hole, you can conveniently realize the assembling of linking arm, and
