In, to reach certain intensity.Generalling use in the prior art is manually to drive piles, this mode working efficiency compared with
It is low, and physical strength is expended, and the depth of guardrail implantation not can guarantee yet.
In the prior art, also have and driven piles using piling machine, in order to facilitate the operation of hand can be arranged on existing piling machine
Structure, existing handle structure is fixed structure, can not be turned folding, and volume is larger when storage.
Summary of the invention
The present invention proposes folding handle structure and piling machine in view of the above-mentioned problems, overcome deficiency.
The technical solution adopted by the present invention is as follows:
A kind of folding handle structure, comprising:
Shell has first positioning hole on side wall；
Support is fixed on shell；
First rotating block is rotatably installed on the support；
Second-hand's handle is rotatably installed on first rotating block, and can be moved along own axes direction, second-hand's handle
End there is the first positioning region, second-hand is also with the first limiting section and the second limiting section, wherein the first limiting section is located at
Side where first positioning region, the first limiting section and the second limiting section are located at the two sides of the first rotating block, for limiting second
Shift motion of the hand handle along own axes；
First pressure spring, housing is in second-hand upper, and one end and the first limiting section cooperate, and the other end is matched with the first rotating block
It closes, for keeping the first positioning region mobile to the direction far from the first rotating block；
The second-hand is having organize work position and folding work position, when organizing work, first positioning region
Axis be overlapped with the axis of first positioning hole, the first positioning hole is protruded into the first positioning region, and second-hand is opposite with shell
It positions.
" support is fixed on shell " described in the application include support and shell be integrally formed part the case where.
Folding handle operating principle: when second-hand is folding station is in, the axis of the first positioning region and the first positioning
The axis in hole is not overlapped, total small volume, at this time by application active force, second-hand's handle being made to do axial direction second-hand
Mobile, the first limiting section overcomes the elastic force of the first pressure spring mobile to the first rotating block side, then rotates second-hand's handle, makes the
First positioning region of two hand handles and first positioning hole unclamp second-hand's handle, under the action of the first pressure spring, the first positioning region to it
First positioning hole is stretched to, second-hand's handle is located on shell by the cooperation of the first positioning region and first positioning hole.
When practice, in order to keep second-hand that volume after folding is smaller, it is preferred that at folding work position, first is fixed
The axis in position portion and the axis of first positioning hole are close to vertical or vertical.
When practice, first positioning hole can be the thread bush being fixed on shell.

The piling machine of the present embodiment further includes folding handle structure, as shown in Fig. 6,7,9 and 10, folding handle structure packet
It includes:
Shell 1 has first positioning hole 22 on side wall；
Support 23 is fixed on shell 1；
First rotating block 24, is rotatably installed on support 23；
Second-hand is rotatably installed on the first rotating block 24 25, and can move along own axes direction, second-hand's handle
25 end has the first positioning region 26, and second-hand also has the first limiting section 27 and the second limiting section 28 25, wherein first
Limiting section 27 is located at 26 place side of the first positioning region, and the first limiting section 27 and the second limiting section 28 are located at the first rotating block 24
Two sides, for limit second-hand 25 along own axes shift motion；
First pressure spring 29, in second-hand on 25, one end and the first limiting section 27 cooperate housing, the other end and the first rotation
Block 24 cooperates, for keeping the first positioning region 26 mobile to the direction far from the first rotating block 24；
Second-hand has 25 to organize work position and folding work position, when organizing work, the axis of the first positioning region 26
Line is overlapped with the axis of first positioning hole 22, and first positioning hole 22 is protruded into the first positioning region 26, and second-hand is opposite 25 and shell 1
It positions.
" support 23 is fixed on shell 1 " described in the application includes support 23 and shell 1 is integrally formed part
The case where.
Folding handle operating principle: when second-hand is in folding station 25, the axis and first of the first positioning region 26
The axis of location hole 22 is not overlapped, total small volume, at this time by applying active force 25 to second-hand, makes second-hand
It axially moves 25, the first limiting section 27 overcomes the elastic force of the first pressure spring 29 mobile to 24 side of the first rotating block, then
Second-hand is rotated 25, make second-hand 25 the first positioning region 26 and first positioning hole 22 to it, release second-hand 25,
Under the action of first pressure spring 29, first positioning hole 22 is stretched in the first positioning region 26, passes through the first positioning region 26 and first positioning hole
Second-hand is located on shell 1 by 22 cooperation 25.
When practice, in order to keep second-hand that 25 volume after folding are smaller, it is preferred that at folding work position, first
