Bar 9 moves backward, and the compression of the first spring 10, the first kelly 9, which moves backward, not to be contacted with the first fixture block 6, because of the first torque spring 3
Effect, the second movable plate 2 restores to lower swing to original position, while contact plate 136 being driven not contact with nail, because of the first spring
10 effect, the first kelly 9, which moves forward, to be restored to original position, while because of the effect of second spring 134, guide sleeve 133 is moved forward
Motion bar 135 is driven to move forward, motion bar 135, which moves forward, drives the forward movement of contact plate 136 to restore to original position.
After nail is limited by upper and lower two sides arc groove 5, operator can pull pulling plate 145 to move right, pulling plate 145
It moves right and 7 type bars 143 is driven to move right, 7 type bars 143, which move right, drives wedge block 142 to move right, wedge block 142
The promotion contact bar 146 that moves right moves down, and contact bar 146, which moves down, drives arc panel 147 to move down, third spring
149 stretch, and arc panel 147 is moved down to contact with nail and is fixed, and stop drag pulling plate 145, i.e., the removable present apparatus will
Nail is moved to the position marked on plank, then constantly rocking the present apparatus wears nail by plank.When plank wears up to conjunction
After suitable degree, the present apparatus is rocked in stopping, unclamping pulling plate 145, because of the effect of third spring 149, arc panel 147 moves up extensive
Multiple to original position, arc panel 147 moves up drive contact bar 146 and moves up, and contacts bar 146 and moves up drive wedge block
142 are moved to the left, and wedge block 142 moves left through 7 type bars 143 and pulling plate 145 is driven to be moved to the left recovery to original position, operator
The i.e. available hammer of member hammers nail in plank.In this way, can prevent from nail and plank friction is small to cause to skid.
When 7 type bars 143 move right, and wedge block 142 is driven to move right, 7 type bars 143 also drive guide rod 16 to move right
It is dynamic, the compression of the 4th spring 17.When operator unclamps pulling plate 145, while because of the effect of the 4th spring 17, guide rod 16 is to moving to left
Dynamic that 7 type bars 143 is driven to be moved to the left, 7 type bars 143, which are moved to the left, drives pulling plate 145 to be moved to the left recovery to original position.In this way, can
Reset pulling plate 145 preferably.
When the present apparatus after use, operator can pull top handle 4 to lower swing, and top handle 4 is to lower swing
When to suitable position, operator pulls the second kelly 20 to lower swing, and the second torque spring 22 stretches, the second kelly 20 to
Lower swing drives the second fixture block 21 to lower swing, and the second fixture block 21 is caught in card slot 19 to lower swing, the second fixture block 21 and card slot
19 cooperations are fixed by upper and lower two side grip 4.When needing using the present apparatus, the second kelly 20 can be pulled, which to swing to the right, makes second
It is detached from fixture block 21 and card slot 19, unclamps the second kelly 20, because of the effect of the second torque spring 22, the second kelly 20 is swung up
It drives the second fixture block 21 to be swung up to restore to original position, while because of the effect of the first torque spring 3, top handle 4 is swung up
Restore to original position.In this way, more convenient carrying of the operator to the present apparatus.
It although an embodiment of the present invention has been shown and described, but for the ordinary skill in the art, can
These embodiments can be changed without departing from the principles and spirit of the present invention with understanding, the scope of the present invention
It is defined by the appended claims and the equivalents thereof.
