Under the hand pressure handle pressed status, connecting rod is under the drive of brace, and hook is retracted into the pivot pin passage with in the interior interconnection, and pressing plate pressed down cylinder was extend in the pivot pin passage under the effect of dipper crowding gear this moment.
Described dipper crowding gear comprises the first moving block that is coupling on main body and the second moving block that is coupling on main body, the A end of described the first moving block is provided with stopper slot, the B end of described the first moving block is provided with the first lug boss, the rear end of described the first lug boss is provided with pit bit, described the first connecting axle and described stopper slot cooperatively interact, the A end of described the second moving block has the second lug boss, described the second lug boss rear end is provided with spacing breach, the B end of described the second moving block is provided with press strip, described the second lug boss and described pit bit cooperatively interact, described the first lug boss cooperates with described spacing breach, described press strip is pressed on the described pressing plate, under the hand pressure handle pressed status, the first moving block is centered by the axis part, and the first moving block A end rotates, the first moving block B end upwards rotates, the second moving block is centered by the axis part at this moment, and the second moving block A end upwards rotates, and the press strip on the second moving block B end presses down pressing plate.
The upper front end of installation portion is provided with the pivot pin storehouse, described pivot pin storehouse communicates with described pivot pin passage, described pivot pin is provided with Compress Spring and push pedal in the storehouse, and an end of described Compress Spring is fixed on the inwall in pivot pin storehouse, and the other end of described Compress Spring is fixed in the push pedal.
Be provided with the spring passage in the pivot pin storehouse, described Compress Spring is arranged in the described spring passage, and described installation portion side is provided with the chute that communicates with the pivot pin storehouse, and described push pedal side is provided with push-pull handle, and described push-pull handle stretches out described chute.
Be provided with groove in the described fixed handle, be connected with adapting rod behind the described connecting rod, described brace is coupling on described adapting rod, and the brace both sides that are positioned at groove ends are equipped with the first pulley, and described the first pulley slides in described groove.
The common outside of pit bit and lug boss is fixedly installed limiting plate.
Described press strip is arranged with the second pulley, and described the second pulley action is on described pressing plate.
Compared with prior art, the invention has the advantages that in the situation of not destroying fingertip surface conductance coating, hook back-moving spring stomidium on the isolating switch with hook first, hand pressure handle is pressed down, brace pulling connecting rod backward, make the hook that hooks the back-moving spring stomidium be retracted into the pivot pin passage with in the interior interconnection, the back-moving spring end is dropped in the open slot, the back-moving spring stomidium is just in time corresponding with the pivot pin passage, this moment is under the effect of dipper crowding gear, pressing plate presses down, the pivot pin that cylinder will be put in the pivot pin passage upper end in advance jacks down, and pivot pin drops in the stomidium of fingertip back-moving spring, then this erecting tools is a little upwards lifted a bit, hook is shifted out from fingertip back-moving spring stomidium, this moment, fingertip back-moving spring end external force disappeared, and under the flexible effect of back-moving spring itself, the back-moving spring that is fixed with pivot pin in the stomidium is fixed on fingertip the both sides of finger mount, repeat above-mentioned steps, can a plurality of fingertips of finger mount both sides are fixing one by one.The present invention presses hand pressure handle the fingertip back-moving spring is pulled out when operation, pivot pin is hammered in the stomidium of fingertip back-moving spring simultaneously, and operation is very easy, can not injure personal safety, can not destroy simultaneously fingertip surface conductance coating when operation.
The setting of the first back-moving spring, upspringing after hand pressure handle is pressed down resets.The setting of the second back-moving spring can make pressing plate upspring after pressing down and reset.
Under the hand pressure handle pressed status, the first moving block is centered by the axis part, the first moving block A end rotates, the first connecting axle is mobile in stopper slot, and the first moving block B end upwards rotates, and the first lug boss of the first moving block B end is with the second lug boss jack-up on the second moving block A end, the second lug boss is upwards rotated, the second moving block is centered by the axis part, and the press strip on the second moving block B end is mobile at pressing plate, simultaneously pressing plate is pressed down.After the second moving block turned an angle, the top of the first lug boss fell in the described spacing breach, prevented that the second moving block is rotated further.
Put into a plurality of pivot pins in the pivot pin storehouse, after the pivot pin on the pivot pin passage was pressed down by cylinder, the pivot pin in the pivot pin storehouse added in the pivot pin passage under the effect of spring and push pedal, avoided filling one by one the trouble of pivot pin.
Be arranged on chute and the push-pull handle of installation portion side, use the manual manipulation push-pull handle, convenient at the in-built pivot pin in pivot pin storehouse.
The setting of adapting rod can be moved the second pulley smoothly on groove, when the setting of the first pulley presses down hand pressure handle, more smooth and easy.
The setting of limiting plate can because long-time the use misplaces, not cooperatively interact more firm the position of pit bit and lug boss.
At press strip when pressing plate moves, the setting of the second pulley power of reducing friction, lighter during operation, also be not easy wearing and tearing.
