Main body 2 is provided preferably with at least one housing bearing 3, and described housing bearing 3 is configured to be contained in main body 2 by guidewire apparatus 4 at least in part movably.First lever 5 and/or the second lever 10 are preferably rotatably mounted to main body in the inside of bearing 3.The leading section 8 of wire guide rob preferably extends from bearing and exposes on the direction of needle bearing mechanism.Trigger equipment is preferably located in bearing inside.

Substantially, the feature of the wire guide rob in the present invention be its can about needle bearing mechanism (cylinder of such as circular knitter) radially (near and away from needle bearing mechanism) and vertically (pin about needle bearing mechanism rises and declines) mobile.This type of wire guide rob is known in the art, and is called vibration wire guide rob, exactly because it can near needle bearing mechanism recalling (except the vertical motion of routine) about needle bearing mechanism.

First actuator is trigger equipment, it makes wire guide rob radial motion (can take out of by wire guide rob and bring the main body of described device into, namely respectively near or away from needle bearing mechanism), and the second actuator make wire guide rob can (first height 101 and second height 102 between) carry out the first vertical motion.Substantially, the setting of two actuators is therefore, it is possible to be defined for the different operating position of four of wire guide rob, as shown in Fig. 9 a-9d: primary importance A(Fig. 9 is a) corresponding to the wire guide rob recalled being in the first height, and second place B(Fig. 9 b) corresponding to the wire guide rob of advance being in the first height, 3rd position C(Fig. 9 c) corresponding to be in second height the wire guide rob recalled, the 4th position D(Fig. 9 d) correspond to advance and be in second height wire guide rob.

The increase of the 3rd actuator 19 also acts on (similar second actuator 15) on the second lever 10, and wire guide rob can be made to drop to third high degree 103 further from the second height 102.3rd actuator, in conjunction with the first actuator 14, wire guide rob can be introduced two other operating positions, as shown in Fig. 9 e-9f: the 5th position E(Fig. 9 e) corresponding to recall and be in the wire guide rob of third high degree, the 6th position F(Fig. 9 f) correspond to advance and be in the wire guide rob of third high degree.

Substantially, the first actuator (control radial motion) makes wire guide rob can pass through between A and B of position, between C and D of position and between E and F of position; Second actuator (controlling the first vertical motion) makes wire guide rob can pass through between position A and C and position B and D; 3rd actuator (controlling further vertical motion) makes wire guide rob can at position C(or A) and E between and at position D(or B) and F between pass through.Utilize the independently actuator that three different, six different operating positions can be obtained.

More detailed analysis will be carried out hereinafter to operating position.

First operating position starts (activation) by the first actuator 14 and the second actuator 15(if any, also have the 3rd actuator) close acquisition: in this position, the leading section 8 of wire guide rob is positioned at the first point (A), and in this some preparation, towards second, vertically height and the 3rd vertical height 103 decline wire guide rob.

Second operating position is obtained by the closedown of the first actuator 14 and the second actuator 15: in this position, the leading section of wire guide rob is positioned at second point (B), this point, or the pin of knitting machine (N) can not be mentioned on alignment, or the line being dispensed to the pin of described machine was brought by syringe needle afterwards before, to interrupt the supply to pin.

3rd operating position obtains (if existed by the startup of the first actuator 14 and the second actuator 15, closedown in conjunction with the 3rd actuator): wherein, the leading section of wire guide rob is positioned at thirdly (C), this point, all pins (N) of knitting machine can pick up line, tape are entered to expect the progress of work of feed mechanism.

4th operating position obtains (if existed by the closedown of the first actuator 14 and the startup of the second actuator 15, closedown in conjunction with the 3rd actuator): in this position, the leading section of wire guide rob is positioned at the 4th point (D), this point, only the pin higher than other pin (N) of knitting machine can be picked up, and other pin rises and littlely therefore can not pick up line.

5th operating position is by the startup of the first actuator 14 and the 3rd actuator 19, and preferably the second actuator 15 closedown obtain, wherein, the leading section of wire guide rob is positioned at the 5th point (E), this point, all pins (N) of knitting machine can pick up line, and described pin (N) is brought into the working environment being in and expecting feeding.

6th operating position is obtained by the closedown of the closedown of the first actuator 14 and the startup of the 3rd actuator 19 and preferably the second actuator 15, wherein, the leading section of wire guide rob is positioned at the 6th point (F), this point, the pin (N) that the rising of knitting machine is less can pick up line, and the pin rising more (N) can not pick up line, because the line of feeding is positioned at tongue (tongue) lower position than the more pin that rises.

The startup (working between E and F of position) of the 3rd actuator, starts while preferably not needing the second actuator.They work in the different piece of the second lever, and each lever that passes to independently in them rotates accordingly, and reach certain angle, and described angle is enough to realize corresponding vertically height.

From kinematics angle, actuator applies specifically to rotate on the first and second levers, and it transfers the motion to wire guide rob in a controlled manner, and therefore wire guide rob is obeyed in rotary moving, and the described wire guide rob that makes in rotary moving is positioned at aforesaid operations position A-F.The motion of lever and wire guide rob can be understood with reference to a series of accompanying drawing 9a-9f and will be described below.

The startup of the first actuator preferably determines rotating forward of the upper end of the first lever and rotating backward of consequential bottom, determines the recalling of pin of the leading section of wire guide rob about the needle bearing mechanism of knitting machine.

The closedown of the first actuator preferably determines the rotation forward of rotating backward of the upper end of the first lever and consequential bottom, determines to advance towards the pin of the needle bearing mechanism of knitting machine in the leading section of wire guide rob.

The closedown of the second actuator preferably determines rotating of the movable end of the second lever, or act on rotating backward of the 3rd lever on the movable end of the second lever, and the upwards rotation of the leading end of consequential second lever, determine the rising of leading section relative to the pin of the needle bearing mechanism of knitting machine of wire guide rob.

The startup of the second actuator preferably determines the upwards rotation of the movable end of the second lever, or act on the rotation forward of the 3rd lever on the movable end of the second lever, and the rotating of the leading end of consequential second lever, determine that the leading section of wire guide rob vertically highly drops to the second vertical height relative to the pin of the needle bearing mechanism of knitting machine from first.

The closedown of the 3rd actuator preferably can not affect the position supposed by the second lever, and the second lever keeps its leading end close with the second actuator or start and rise respectively or decline.

The startup of the 3rd actuator preferably determines the upwards rotation of the movable end of the second lever, and further the rotating of the leading end of consequential second lever (what apply relative to the second actuator rotates), determine the leading section of wire guide rob relative to the needle bearing mechanism of knitting machine pin vertically highly drop to the second vertical height from first further, until the 3rd vertical height.

Substantially, the startup of the 3rd actuator determines that upwards rotating of the movable end of the second lever is greater than upwards rotating accordingly of the second actuator applying, and the leading end of the second lever thus rotate rotating accordingly of being greater than that the second actuator applies, therefore determine that the leading section of wire guide rob declines further relative to the pin of the needle bearing mechanism of knitting machine, enter the 3rd vertical height more than the second height.

Based on the structure of trigger equipment and elastic devices, the correlation between the state of actuator and the position of wire guide rob is summarized as follows table:

?	First actuator	Second actuator	3rd actuator
				Position A	Start	Close	Close
Position B	Close	Close	Close
				Position C	Start	Start	Close
Position D	Close	Start	Close
				Position E	Start	Close	Start

Position F

Close

Start

These three actuators all can independent of being controlled each other and operating: this means can either desirably three vertically height 101, between 102 and 103, again can near or away from the leading section of needle bearing mechanism movable conducting wire part: that is, by the combination of the startup and closedown of selecting correct actuator, six positions A, B, C, D, E and F can be selected and can by desirably between which through to arrive described six positions.By just not needing the transition through " centre " point (such as there is vertically height placed in the middle or close needle bearing mechanism or away from needle bearing mechanism) between " at a distance " point (namely have different vertically or the point of radial height).

Especially, can through three vertical height 101 to 103, and do not need to start or close the second actuator (but directly with the 3rd actuators acts), and need not consider that starting point and ending point (by acting directly on the first actuator) is selected in some A, C, E and B, radial motion between D, F.

It should be noted that the guidewire apparatus in the present invention preferably constructs by this way, namely when three actuators are cut out, wire guide rob is automatic in-position B under the effect of elastic devices.Such setting is favourable, because position B is the normal operation position of wire guide rob, than the position that other position more often maintains during being machine run.In this way, described position without any need for power effect (not having actuator to start), because this reducing the loss of actuator and limiting the structural pressure acting on described device.
