Disadvantageously, retainer ring can be from the working end slippage of pin shape.The longitudinal axis of known pin favours the longitudinal axis of handle member, to avoid this slippage.
Summary of the invention
It is a kind of for packing the pliers of retainer ring into that task of the present invention is to provide, by further improving the clamping of retainer ring and avoid especially reliably retainer ring slippage from pliers for packing the pliers of retainer ring into.
Task of the present invention solves for packing the pliers of retainer ring into by a kind of, described pliers has two handles parts, this two handles part has respectively a longitudinal axis and a working end, each working end is configured to be arranged on the pin on one of handle member, described pin has breach, and described breach is provided with the surface that the surface that starts obliquely and/or the end structure that deviates from handle member of described breach are precipitous rising from the end towards handle member.
Of the present invention have two handles parts for packing the pliers of retainer ring into, this two handles part has respectively a longitudinal axis and a working end, each working end is configured to be arranged on pin on one of handle member, that have longitudinal axis, it is characterized in that, described pin has breach.In addition in the time of in the corresponding recess that is especially configured to through hole of each pin embedding retainer ring, the edge of breach forms projection, this projection and the edge of retainer ring can engage and act on especially from behind the edge of retainer ring, to prevent reliably by this way retainer ring slippage from pin, because retainer ring is kept by breach.
In a kind of preferred enforcement modification, landolsring is constructed around ground, to can avoid reliably retainer ring slippage in each position of pliers.
According to a kind of particularly preferred flexible program of the present invention, breach is only arranged on the outside of pin or is only arranged on the inner side of pin, to avoid unnecessarily weakening the cross section of pin and reduce the possibility that pin produces specified fracture position.At this, the surface that deviates from another pin is counted as outside, and correspondingly the surface towards another pin of pin is counted as inner side.According to what relate to, be for packing outer retainer ring or the pliers of interior retainer ring into, breach being correspondingly only arranged on to the outside of pin or being only arranged on the inner side of pin.
Preferably the end towards handle member of breach is arranged on the only about half of length place of pin, to the fulcrum of retainer ring is moved on near handle as far as possible only, thereby reduces by this way because lever principle is applied to the power on pin and avoids the fracture of pin.
By a kind of particularly preferred embodiment of the present invention, breach be configured to from the end towards handle member of breach, start obliquely and preferably with the surface of precipitous rising, finish.Being formed for by this way the end that deviates from handle member retainer ring, particularly advantageous area supported, especially breach is fixed on retainer ring on the pin of pliers reliably.The surface of the precipitous rising of surface ratio starting especially obliquely at this has less inclination angle with respect to the longitudinal axis of pin.
Preferably the longitudinal axis of pin favours the longitudinal axis of handle member, to further improve by this way the clamping of retainer ring on pin.
According to of the present invention preferred embodiment a kind of; the extended line of the longitudinal axis of handle member is arranged in the surface starting obliquely of breach or with respect to arranging parallel staggering of this surface; because the plane of retainer ring is substantially perpendicular to the longitudinal axis extension of handle member conventionally; and guarantee by this way ring be bearing in as much as possible breach on the end of handle member, the fulcrum that makes retainer ring is as far as possible near the handle member of pliers.
According to of the present invention preferred embodiment a kind of, according to what relate to, be for packing outer retainer ring or the pliers of interior retainer ring into, pin arranges and the breach sold is arranged on outside away from each other from handle member, or from handle member, setting and breach are arranged on inner side, to prevent especially reliably retainer ring slippage pin obliquely toward each other.
Advantageously, the surperficial gradient starting obliquely of breach is more precipitous than the contact surface of retainer ring, guarantee that thus the supporting-point of retainer ring on pin is never positioned on the extremely outside of opening and makes thus the fulcrum of retainer ring as far as possible near handle member, thereby reduce to be applied to the power on pin.
Accompanying drawing explanation
According to accompanying drawing below, describe the present invention in detail.Accompanying drawing is as follows:
Fig. 1 is for packing the perspective view of the pliers of interior retainer ring into;
Fig. 2 is according to another enlarged perspective of the pliers of Fig. 1;
Fig. 3 is for packing the perspective view of the pliers of outer retainer ring into.
The specific embodiment
Fig. 1 and 2 shows for packing the different views of the pliers 10 of interior retainer ring 30 into, interior retainer ring be only configured to part around ring, its free end has respectively the through hole 32 extending perpendicular to the plane of retainer ring 30, pliers 10 can insert in through hole.To this, pliers 10 has longitudinal axis l with two
g handle member 12, this two handles part has longitudinal axis l with one respectively at its free end
spin 16 as working end.Pin 16 is arranged in the extended line of handle member 12 substantially, at this, and longitudinal axis l
s, l
gcan overlap.But according to the embodiment shown in Fig. 1 and 2, can construct in this wise pliers 10, make the longitudinal axis l of pin 16
sfavour the longitudinal axis l of handle member 12
g, especially make two pins 16 arrange obliquely toward each other from handle member.Because two pins 16 insert in through holes 32 and two have a pin 16 handle member 12 is in order to pack interior retainer ring 30 in the inside groove of member and move toward one another has resisted retainer ring 30 from pin 16 slippages by this inclination of pin 16.
In order reliably to prevent that retainer ring 30 is from pin 16 slippages, each pin 16 has the breach 20 that can cause around ground, but according to the embodiment shown in Fig. 1 and 2, breach is only arranged on the inner side of pin 16, to weaken as few as possible by this way the cross section of pin 16 and substantially just guaranteeing to prevent retainer ring 30 slippages in the actual region being adjacent on pin 16 of retainer ring 30 when clamping retainer ring 30 by pliers 10.Breach 20 has towards the end 21 of handle member 12 and deviates from the end 22 of handle member 12, preferably the end 21 towards handle member 12 of breach 20 is arranged on to the only about half of length place of pin 16.Breach 20 is preferably constructed asymmetrically.To this, breach 20 has the surface 24 especially starting obliquely from the 21s, end towards handle member 12, and the end that deviates from handle member 12 22 of breach 20 preferably consists of the surface 26 of precipitous rising.At this, the surface 24 starting especially is obliquely the longitudinal axis l with respect to pin 16 than the surface of precipitous rising 26
sthere is less inclination angle.The surface 24 starting obliquely preferably favours the longitudinal axis l of pin 16 in this wise
s, make the longitudinal axis l of handle member 12
gin the surface starting obliquely 24 of breach 20, extend or with respect to arranging parallel staggering of this surface.The surface 26 of precipitous rising can be substantially perpendicular to the longitudinal axis l of pin 16 at this
sextend, but preferably approximately perpendicular to the longitudinal axis l of handle member 12
gextend.The inclination on the surface 24 starting is obliquely preferably precipitous than the area supported of retainer ring 30, so that guarantee retainer ring 30 be substantially bearing in breach 20 on the end 21 of handle member 20 and make thus the fulcrum of retainer ring 30 be positioned as close to handle member 12, to avoid excessive power to be applied on pin 16.
Fig. 3 shows for packing the perspective view of the pliers 10' of outer retainer ring 30' into.The difference of the pliers 10 of this pliers 10' and interior retainer ring 30 is only: pin 16 is obliquely installed away from each other from handle member 12s and breach 20 is arranged on the outside of pin 16.When packing retainer ring 30' into, move away from each other in the work end with pin 16 of handle member 12, to can strut simply retainer ring 30' and this retainer ring be packed in the water jacket of member.
