Block is slided, and is separated with half tooth block, now lift arm is swingable, behind regulation swing arm position, release handle, and the engagement of tooth block is lifted
Rise arm to be lockable, because regulation swing arm position is carried out after storing cycle, now handle is located at vehicle chassis edge,
Operating personnel need to stretch into chassis to pull handle by hand, while adjusting swing arm position, inconvenient operation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of single-column lifting machine front swing arm auto-unlocking device, and it is used
Automatic unlocking structure, lifting machine only need to be minimized position, just can directly adjust lift arm position, without operation during rising,
Lift arm is lockable automatically, it is ensured that lifting machine safely and smoothly works, and is solved the problem of prior art is present, is more fitted
Practice, it is easy to operate.
The present invention is to solve above-mentioned technical problem by following technical proposals：A kind of single-column lifting machine front swing arm is automatic
Tripper, it includes lift arm, pallet, the first supporting plate, tooth block, the first spring, second spring, gangbar, half tooth block,
One handle, the first connecting plate, the second connecting plate, adjusting screw, push rod, second handle, the second supporting plate, lift arm and pallet phase
Even, the first supporting plate is located at lift arm bottom, and tooth block connects with second spring, and the first spring is located on the left of tooth block, second handle
Above tooth block, gangbar connects with first handle, and half tooth block is located on the right side of gangbar, and lift arm connects with half tooth block, the
One handle is located above second handle, and second spring is connected with adjusting screw by push rod, the first connecting plate and the second connecting plate
Mutually fixed, the second connecting plate is located on the right side of push rod, and gangbar connects with the first connecting plate, and tooth block is located on the right side of the first connecting plate,
Half tooth block is connected with tooth block, and the second supporting plate is located at push rod bottom.
Preferably, the half tooth block is shaped as zigzag.
Preferably, the second spring is shaped as helical form.
Preferably, the push rod is shaped as cylinder.
Preferably, first supporting plate is shaped as strip.
The positive effect of the present invention is：The present invention uses automatic unlocking structure, need to only minimize lifting machine
Position, just can directly adjust lift arm position, and without operation during rising, lift arm is lockable automatically, it is ensured that lifting machine is safe, flat
Quietly work, solve the problem of prior art is present, practice of more fitting is easy to operate.

Embodiment
Present pre-ferred embodiments are provided below in conjunction with the accompanying drawings, to describe technical scheme in detail.
As shown in figure 1, single-column lifting machine front swing arm auto-unlocking device of the present invention include lift arm 1, pallet 2, first
Fagging 3, tooth block 4, the first spring 5, second spring 6, gangbar 7, half tooth block 8, first handle 9, the first connecting plate 10, second connect
Fishplate bar 11, adjusting screw 12, push rod 13, second handle 14, the second supporting plate 15, lift arm 1 are connected with pallet 2, the first support
Plate 3 is located at the bottom of lift arm 1, and tooth block 4 connects with second spring 6, and the first spring 5 is located at the left side of tooth block 4, and second handle 14 is located at
The top of tooth block 4, gangbar 7 connects with first handle 9, and half tooth block 8 is located at the right side of gangbar 7, and lift arm 1 connects with half tooth block 8,
First handle 9 is located at the top of second handle 14, and second spring 6 is connected with adjusting screw 12 by push rod 13, the first connecting plate 10
Mutually fixed with the second connecting plate 11, the second connecting plate 11 is located at the right side of push rod 13, gangbar 7 connects with the first connecting plate 10, tooth
Block 4 is located at the right side of the first connecting plate 10, and half tooth block 8 is connected with tooth block 4, and the second supporting plate 15 is located at the bottom of push rod 13.
Half tooth block 8 is shaped as zigzag, so convenient regulation lift arm position.
