Face, and the depth on the first fixed link 2 insertion ground is adjusted, make the first tablet 1 vertical with timber 40, then pass through connecting rod 3
First tablet 1, by multiple holding 14 circumference uniform distributions of block in the compact heap 13 of 3 upper end of connecting rod, afterwards by one end of rope 12
The lower end of connecting rod 3 is fixed on, the other end of rope 12 is fixed on the first shop bolt 18 or the second positioning pin around fixed pulley
On nail 23, and adjusting 12 length of rope makes rope 12 be in tensioning state.
After above-mentioned state is adjusted, the state between connecting rod 3 and compact heap 13 can be to be fixedly connected with and separate two kinds
State.
When being fixedly connected between compact heap 13 and connecting rod 3, it is using process：Pull down 40 left and right sides of timber
Compression bar 5 outer end, since compression bar 5 and connecting rod 3 contact, so 5 inner end of compression bar can drive connecting rod 3 to move up, when even
Extension bar 3 is fixedly connected with compact heap 13, since the inclined-planes of multiple holding blocks 14 form up big and down small taper surface, and taper surface
End diameter is located between the end diameter and outside diameter of 13 conical cavity of compact heap, so when compact heap 13 moves up,
The inner conical surface of compact heap 13 squeezes the male cone (strobilus masculinus) for holding block 14 tightly, so that holding block 14 tightly holds timber 40 tightly；At the same time connecting rod 3
When moving up, rope 12 can be pulled and the first shop bolt 18 or the second shop bolt 23 is driven to move, due to holding block 14 tightly
When holding timber 40 tightly, distance that compact heap 13 moves upwards and when making the first shop bolt 18 be separated with ratchet bar 20, first determines
The distance that position pin 18 moves is consistent or makes the distance of the second shop bolt 23 removal locating slot 22 consistent, so holding block tightly
During 14 holding timber 40, second sleeve 10 moves clockwise under the action of 15 or first tension spring 16 of torsional spring, so that
It obtains clamping block 9 and unclamps timber 40, adjust the length of rope 12 to relaxation state, continue to pull down compression bar 5, compact heap 13 continues
It moves upwards, while by holding block 14 tightly timber 40 is driven to move upwards, be pulled up timber 40.
Check the state that timber 40 is pulled out, it, can be again when the above process can not be such that timber 40 loosens completely and be pulled out
Secondary rotation second sleeve 10 counterclockwise or 4th sleeve 21, make the clamping timber 40 again of clamping block 9；Block 14 and pressure will be held tightly afterwards
Tight block 13 unclamps timber 40, adjusts 5 angle of compression bar to original state, the position so as to adjust compact heap 13 relatively with timber 40,
And the length of rope 12 is adjusted, rope 12 is made to be in tensioning state, pulls down the outer end of the compression bar 5 of 40 both sides of timber again,
Similarly, timber 40 can be held tightly by holding block 14 tightly, and clamping block 9 unclamps timber 40 so that timber 40 is pulled out again, and so on, directly
It loosens and is pulled out completely to timber 40.
When being separated between compact heap 13 and connecting rod 3, there are two types of states for such situation：Compact heap 13 and connecting rod 3 it
Between no third compression spring 30 connect and connected between compact heap 13 and connecting rod 3 by the 3rd compression spring 30.
When separating between compact heap 13 and connecting rod 3 and being connected between the two without the 3rd compression spring 30, process is used
It is：The outer end of the compression bar 5 of 40 left and right sides of timber is pulled down, since compression bar 5 and connecting rod 3 contact, so 5 inner end meeting of compression bar
Connecting rod 3 is driven to move up.And when so that the connecting rod 3 is contacted with compact heap 13 due to the effect of gravity, connecting rod 3 can drive
Compact heap 13 moves up, similarly due to holding block 14 and the shape and structure of compact heap 13, so when compact heap 13 moves up
When, timber 40 can be held tightly by holding block 14 tightly, while when connecting rod 3 moves up, can be pulled rope 12 and be driven the first shop bolt
18 or second shop bolt 23 move, and clamping block 9 is caused to unclamp timber 40, adjusts the length of rope 12 to relaxation state, after
Continuous to pull down compression bar 5, compact heap 13 continues up, while by holding block 14 tightly timber 40 is driven to move upwards, and makes wood
Stake 40 is pulled up.
Check the state that timber 40 is pulled out, it, can be again when the above process can not be such that timber 40 loosens completely and be pulled out
Secondary rotation second sleeve 10 counterclockwise or 4th sleeve 21, make the clamping timber 40 again of clamping block 9；The second pin 37 is adjusted afterwards
The position coordinated with first through hole 36 makes the second pin 37 be located at the hole of the top in the hole with once coordinating before first through hole 36
It is interior, during adjustment, due to 9 clamping timber 40 of clamping block, so timber 40, which will not drive, holds block 14 and clamping block 9 tightly to moving down
It is dynamic, the length of rope 12 is thus can adjust, when so that the rope 12 be in tensioning state, 5 upper end of compression bar and 13 lower end of compact heap have one
Fixed distance, this distance are not less than and make the first shop bolt 18 and 20 separated distance of ratchet bar or make the second shop bolt 23
Remove the distance of locating slot 22；The outer end of the compression bar 5 of 40 both sides of timber is pressed, connecting rod 3 drives the movement of rope 12 to make first to determine
Position pin 18 separates with ratchet bar 20 or the second shop bolt 23 is made to remove locating slot 22, so that clamping block 9 unclamps timber 40,
Connecting rod 3 may not contact also with holding block 14 tightly at this time, timber 40 and clamping block 9 have it is slight move down, but move away from
From smaller, the process of entire pile pulling is not influenced.
When being separated between compact heap 13 and connecting rod 3 and being connected with three compression springs 30 between the two, it is using process：
When pulling down the outer end of the compression bar 5 of 40 left and right sides of timber, the inner end of compression bar 5 can drive connecting rod 3 to move up, due to this
When connecting rod 3 the top not end contact with the hole of the lower section of stepped hole 29, so the upper end of connecting rod 3 can compress the 3rd pressure
Spring 30, while the lower end of connecting rod 3 can pull rope 12, rope 12 drives the first shop bolt 18 or the second shop bolt 23,
Since the length that the 3rd compression spring 30 is compressed not less than the first shop bolt 18 and 20 separated distance of ratchet bar or makes second to determine
Position pin 23 removes the distance of locating slot 22, so second sleeve 10 can be released, so that two clamping blocks 9 unclamp timber
40, continue to press the outer end of the compression bar 5 of 40 left and right sides of timber, compact heap 13 is continued to move up, held tightly by holding block 14 tightly
Timber 40, so that timber 40 is pulled up.
Check the state that timber 40 is pulled out, it, can be again when the above process can not be such that timber 40 loosens completely and be pulled out
Secondary rotation second sleeve 10 counterclockwise or 4th sleeve 21, make the clamping timber 40 again of clamping block 9；The second pin 37 is adjusted afterwards
The position coordinated with first through hole 36 makes the second pin 37 be located at the hole of the top in the hole with once coordinating before first through hole 36
It is interior and in the angle identical with initial state, the length of rope 12 is adjusted, rope 12 is made to be in tensioning state.It is pressed downward again
The outer end of the compression bar 5 of dynamic 40 left and right sides of timber, 3 upper end of connecting rod can first compress the 3rd compression spring 30, and clamping block 9 unclamps wood at this time
Stake 40, when clamping block 9 unclamps timber 40, the 3rd compression spring 30 of top is compressed, and the 3rd compression spring 30 gives top compact heap 13 1
A upward power prevents compact heap 13 and timber 40 from declining；Continuing to pull down the outer end of compression bar 5, timber 40 is pulled out again,
And so on until timber 40 is all loosened and is pulled out.
The cooperation for the male cone (strobilus masculinus) that the present invention is made up of the cone-shaped cavity of compact heap 13 with holding block 14 tightly, can make entirely to fill
It puts and, to hold the inside pressing force of block 14 1 tightly, ensures to hold block 14 tightly during pile pulling to by compact heap 13 in uphill process
It will not be produced relative sliding between timber 40, effect is held tightly so as to reach preferable.
The present invention in withdrawal process, is turned upward pile pulling power using compression bar 5 by the cooperation of compression bar 5 and connecting rod 3
The pressure for pulling down compression bar 5 is turned to, reduces operation difficulty；And since compression bar 5 has certain width, it is possible to increase force
Area so that operator can be used hand by or foot the modes such as step on and exert a force；And utilize lever principle so that entire withdrawal process
It is more laborsaving.
The present invention in upward pile pulling, makes clamping block 9 depart from timber 40 by holding the cooperation of block 14 and clamping block 9 tightly,
