Specific embodiment
The preferred embodiment in the utility model is illustrated below in conjunction with attached drawing:
As shown in Figures 1 to 3, a kind of operation readiness formula mounting and dismounting tool, comprising: screwdriver ontology, transmission device and tune
Control component.
Wherein, screwdriver ontology comprising handle 1 and knife bar 2, described 2 one end of knife bar are interspersed on 1 one end of handle and can
1 rotation of opposite handle；It is equipped in 1 one end of handle and is adapted hole with 2 diameter of knife bar, 2 one end of knife bar is interspersed in the hole and can phase
Self-axis line is rotated.
Transmission device comprising rectangular fixed frame 3 and transmission component, rectangular 3 one frame of fixed frame are fixed on handle 1
On one end, described 2 one end of knife bar also extends through a corresponding frame of rectangular fixed frame 3, the transmission group when being interspersed in 1 one end of handle
Part is located in rectangular fixed frame 3 and also connect simultaneously with knife bar 2 and rectangular fixed frame 3；Specifically, the transmission component includes the
One straight bevel gear 4, the second straight bevel gear 5, ratchet 6 and connecting rod 7, first straight bevel gear 4 are fixed on knife bar 2
On, second straight bevel gear 5 and ratchet 6 are sequentially fixed on 7 one end of connecting rod, second straight bevel gear at intervals
5 engage with the first straight bevel gear 4, and 7 other end of connecting rod is hinged on rectangular fixed frame 3 and edge extends to rectangular fixed frame
3 outsides.
Regulatory component is located on rectangular fixed frame 3 and acts on transmission component, and promotes knife bar rotation；Specifically,
The regulatory component includes bending connecting rod 8, ratchet 9, holding rod 10 and the first torsional spring 11, and described 8 one end of bending connecting rod is set in company
On 7 other end of extension bar, described 9 one end of ratchet is hinged on bending connecting rod 8, the other end acts on ratchet 6, in bending connecting rod 8
It is equipped with hinged seat board 12,9 one end of ratchet and hinged seat board 12 and articulated connection is realized by an interspersed pin shaft 13, to promote ratchet
9 other ends can effectively cooperate with ratchet 6, can install the second torsional spring 14 additional in the hinged place of ratchet 9 and bending connecting rod 8, specifically
, the second torsional spring 14 is arranged on pin shaft, 14 one end of the second torsional spring is connect with hinged seat board 12, the other end and ratchet 9 connect, the
Two torsional springs 14 can promote 9 other end of ratchet to be bonded ratchet 6 always, and it is another that described 10 one end of holding rod is fixedly provided at bending connecting rod 8
On end, first torsional spring 11 is set on 7 other end of connecting rod and one end is connect with rectangular fixed frame 3, the other end and bending
Connecting rod 8 is fixedly connected.
The application method and working principle of the utility model:
When the utility model is used, 1 part of palm grip handle, makes the cross bladed cutter head or flat sword of 2 other end of knife bar
Cutter head is corresponding with screw, and then finger can exert a force and holding rod 10 is promoted to deflect to handle 1 and approach；When holding rod 10 is deflected to handle 1
When approach, holding rod 10 will drive bending connecting rod 8 to rotate around 7 other end of connecting rod, while the first torsional spring 11 being promoted to be compressed；Bending
Connecting rod 8 can promote ratchet 9 that ratchet 6 is driven to rotate while movement；The rotation of ratchet 6 will drive connecting rod 7 and the second straight-tooth to bore tooth
Wheel 5 rotates synchronously；Since 8 one end of bending connecting rod is set on 7 other end of connecting rod, the rotation of connecting rod 7 and folding
The rotation of curved rod 8 will not generate interference；The rotation of second straight bevel gear 5 will drive the first straight bevel gear 4, the first straight-tooth cone
Gear 4 then drives 2 rotation of knife bar, to realize the operation for screwing or unscrewing screw；And after unclamping holding rod 10, then the first torsional spring
Then promote 8 integral reset of holding rod 10 and bending connecting rod under the action of 11, and ratchet 9 is on ratchet 6 in 8 reseting procedure of bending connecting rod
It creeps, does not drive ratchet 6 to rotate, so that knife bar 2 will not be made to rotate again；In this way when reciprocating operation holding rod 10, knife bar 2 can be made
It constantly rotates in the same direction, and then promotes screw by whiz or screw.
