The flat knitting machine is an automatic machine with high technical content in the knitting machine industry, and integrates the technologies of computer digital control, electronic driving, mechanical design and the like. The flat knitting machine needs to start the bottom before weaving the weaving piece, and pulls the bottom fabric to continue subsequent weaving after the bottom start is finished. In order to reduce the waste of the raising fabric, the fabric sheet is generally raised by a raising device at present.

The bottom lifting device comprises a bottom lifting plate, a locking screw, a lifting seat and a motor, the lifting seat is connected with the bottom lifting plate, the lifting seat is provided with a threaded hole, and the lifting seat is sleeved on the screw rod through the threaded hole. The lifting seat is matched with the screw rod to form a screw rod nut mechanism. The motor is used for driving the screw rod to rotate, and the screw rod drives the lifting seat to lift. Wherein, the rising bottom plate has a plurality of rising end needles that set up in proper order at interval, and each rises end needle and all has the pinhole. The needle holes are matched to form a wire passing channel. When the weaving piece is subjected to bottom lifting, a knitting mechanism of the flat knitting machine firstly weaves a bottom lifting coil between every two adjacent needle holes, and then the blocking wire passes through the wire passing channel and the bottom lifting coil between every two adjacent needle holes. After the blocking wire passes through the wire passing channel, the motor drives the screw rod to rotate, the screw rod drives the lifting seat to move so as to draw the lifting plate to descend, the blocking wire moves together under the driving of the lifting plate so as to tightly sleeve the lifting coils on the blocking wire, the blocking of the lifting coils by the blocking wire is realized, and then the weaving mechanism can weave back and forth by using weaving wires.

In the technical scheme, the operation of the motor is controlled by the controller, specifically, the time for the locking wire to pass through the wire passing channel is preset in the controller, when the locking wire starts to enter the wire passing channel, the controller starts to time, and after the time is up, the controller controls the motor to operate so as to drive the starting plate to descend. However, the phenomenon that the backing pin is broken to block the wire feeding channel often easily occurs because the backing pin is small. Once the threading channel is blocked, the sealing wire cannot pass through the threading channel within a preset time. Meanwhile, the lock wire still has a phenomenon of deviating from a pinhole in the wire threading process, and after the preset time is over, the controller still controls the motor to drive the lifting plate to be pulled down, so that the lifting failure is caused, and the problem needs to be solved aiming at the situations.

In this way, the length of the third guide bar 132 extending out of the first connecting block 133 can be adjusted to accommodate installation errors in the field. The first hall sensor 134 is disposed on the first connection block 133, and preferably, the first hall sensor 134 is fixed to the first connection block 133 by screws. The movable member is a sleeve 136 disposed on the third guiding rod 132, and preferably, a gap is formed between the sleeve 136 and the third guiding rod 132, so that the sleeve 136 can slide along the third guiding rod 132. Wherein the sleeve 136 is adapted to be pushed along the third guiding rod 132 to the aforementioned triggering position. The third guide bar 132 may be a square bar to limit the sleeve 136 and prevent the sleeve 136 from rotating on the third guide bar 132.

In the above example, the third guide rod 132 is arranged to guide the sleeve 136, so that the movement precision of the sleeve 136 can be improved, and then the sleeve 136 can drive the magnetic member to precisely move to the aforementioned triggering position, thereby avoiding the occurrence of a situation of triggering failure due to movement deviation.

The locking wire 3 is used for abutting against the pushing block 137 when passing through the wire passing channel, so that the sleeve 136 is pushed to move through the pushing block 137. Since the lock wire 3 often needs to push the push block 137 against, in order to reduce the wear of the push block 137, the push block 137 may be made of a wear-resistant material. And because the push block 137 can be disassembled relative to the sleeve 136, when the push block 137 is damaged, the push block 137 can be disassembled in time for replacement, thereby having lower maintenance cost.

As shown in fig. 7, the pushing block 137 may further have a limiting groove 1371, and the locking wire 3 is inserted into the limiting groove 1371 to push the pushing block 137.

One end of the L-shaped support arm is connected with the side wall of the base cylinder, and the other end is provided with the limit groove 1371. The L-shaped support arm and the base cylinder can be of an integrally formed structure, such as integral injection molding.

Further, the detecting mechanism 13 may further include an elastic member, and the elastic member is named as a first elastic member for distinguishing from the elastic member described below. The first elastic member is used for providing a force for withdrawing the sleeve 136 from the triggering position, so that the sleeve 136 can be automatically reset, thereby saving labor.

Further, as shown in fig. 7, the zero-interval yarn intelligent bottom-lifting device of the present invention may further include a base 15. The height of the detection mechanism 13 arranged on the base 15 and on the base 15 is adjustable, so that the height of the detection mechanism 13 can be adjusted according to actual conditions on site, and the practicability is better.

In order to realize the function that the detecting mechanism 13 can be lifted relative to the base 15, the present invention further provides an embodiment, as shown in fig. 7, the detecting mechanism 13 may further include a second connecting block 131, the first connecting block 133, the second connecting block 131 and the third guiding rod 132 are relatively fixed, and preferably, the third guiding rod 132 sequentially passes through the first connecting block 133 and the second connecting block 131. The first connecting block 133 and the second connecting block 131 are both connected to the third guide rod 132 by screws, and the third guide rod 132 is detachable from the first connecting block 133 and the second connecting block 131 by screws.

In the above example, the first screw 512 is loosened, the height of the entire detection mechanism 13 is adjusted by adjusting the position of the second connection block 131, and the first screw 512 is tightened after the position is adjusted to a proper position, so that the second connection block 131 is fixed at the adjusted position, and the entire detection mechanism 13 is also located at the adjusted height position.

The wire collecting and feeding mechanism can be arranged on the starting plate 1, so that the wire collecting and feeding mechanism can move synchronously with the starting plate, and the interference of the starting plate 1 on the wire collecting and feeding mechanism is reduced. The wire receiving and feeding mechanism can be directly arranged on the lifting plate 1, and can also be indirectly arranged on the lifting plate 1 through other components. For convenience of installation, it is preferable that the rising plate 1 is provided with a mounting plate 31, and the wire winding and feeding mechanism is arranged on the mounting plate 31.

Here, it should be noted that: in order to save components, the mounting plate 31 may be one of the connectors 25 as described above, as shown in fig. 3. In short, both the mounting plate 31 and the one connector 25 described above may be the same component.

In order to realize the functions of the wire winding and feeding mechanism, as shown in fig. 9, the wire winding and feeding mechanism includes a driving mechanism, a clutch transmission mechanism, a wire winding wheel 32 and a wire feeding wheel. The wire winding wheel 32 and the wire feeding wheel are both rotatable, e.g. both may be mounted on the mounting plate 31 by means of an axle so as to be rotatable on the mounting plate 31 about a respective axle axis. The wire winding wheel 32 is used to wind the wrapping lock wire 3. The filament winding wheel 32 can wind the locking filament 3 on the wheel surface. Preferably, the wheel surface of the wire winding wheel 32 may be provided with a circumferentially extending accommodating groove 321, and the accommodating groove 321 is annular. The locking wire 3 may be wound in the receiving groove 321 to prevent the wire from coming off from both axial ends of the wire winding wheel 32.

As shown in fig. 10, the aforementioned wire feeding wheel includes a first wire feeding wheel 33 and a second wire feeding wheel 34, and both the first wire feeding wheel 33 and the second wire feeding wheel 34 are configured to clamp the lock wire 3 by the wheel surface and rotationally cooperate to drive the lock wire 3 to move so as to feed the lock wire 3. The "movement" may also be referred to herein as "advancing" in some instances, i.e., feeding the locking wire 3. The term "rotationally engaged" as used herein means that the first wire feeding wheel 33 and the second wire feeding wheel 34 rotate in opposite directions, for example, when the first wire feeding wheel 33 rotates in the forward direction, the second wire feeding wheel 34 rotates in the reverse direction; or when the first yarn feeding wheel 33 rotates reversely, the second yarn feeding wheel 34 rotates normally.

The aforementioned driving mechanism is used to drive the wire winding wheel 32 to rotate. The clutch transmission mechanism is used for engaging the transmission connection between the wire winding wheel 32 and the first wire feeding wheel 33 and/or the second wire feeding wheel 34 during wire feeding so as to enable the first wire feeding wheel 33 and the second wire feeding wheel 34 to be in rotating fit; and disconnecting the drive connection during take-up. Specifically, when feeding the wire, the wire winding wheel 32 may be in transmission connection with one of the first wire feeding wheel 33 and the second wire feeding wheel 34 through a clutch transmission mechanism, or in transmission connection with both the first wire feeding wheel 33 and the second wire feeding wheel 34, so that the first wire feeding wheel 33 and the second wire feeding wheel 34 are in rotation fit to drive the lock wire 3 to move, so as to feed the lock wire 3. When the wire is wound, the clutch transmission mechanism is disconnected from the transmission connection, and at the moment, the driving mechanism drives the wire winding wheel 32 to rotate, and the wire winding wheel 32 winds the locking wire 3.

As shown in fig. 9, the technical scheme of the utility model owing to rotate through actuating mechanism drive winding wheel 32 when receiving the silk, winding wheel 32 directly pulls the lock silk 3 and carries out the rolling to changed and tightly received the mode of silk through two wire feeding wheel clamps among the prior art, and then avoided among the prior art because frictional force inadequately leads to the phenomenon that lock silk 3 skidded between two wire feeding wheels. In addition, the clutch transmission mechanism disconnects the transmission connection between the wire winding wheel 32 and the first wire feeding wheel 33 and/or the second wire feeding wheel 34 during wire collection, so that the deformation of the blocking wire 3 caused by clamping and strong pulling of the first wire feeding wheel 33 and the second wire feeding wheel 34 during wire collection can be avoided.

The wire winding wheel 32 can be directly connected with the first wire feeding wheel 33 and/or the second wire feeding wheel 34 in a transmission way, and can also be indirectly connected with the first wire feeding wheel 33 and/or the second wire feeding wheel 34 in a transmission way, namely, the transmission connection between the wire winding wheel 32 and the first wire feeding wheel 33 and/or the second wire feeding wheel 34 is realized through other intermediate components. Hereinafter, the following case will be described as an example, and as shown in fig. 11, the clutch transmission mechanism is a gear transmission mechanism. A first gear 36 is fixedly sleeved on a wheel shaft of the first wire feeding wheel 33, a second gear 37 is fixedly sleeved on a wheel shaft of the second wire feeding wheel 34, and a driving gear 35 is fixedly sleeved on a wheel shaft of the wire winding wheel 32. In a specific application example, the first gear 36, the second gear 37 and the driving gear 35 may be fastened to the corresponding axles by keys, such that the first gear 36 may drive the first wire feeding wheel 33 to rotate synchronously when rotating, the second gear 37 may drive the second wire feeding wheel 34 to rotate synchronously when rotating, and the driving gear 35 may drive the wire winding wheel 32 to rotate synchronously when rotating.

Wherein the clutch transmission engages or disengages the transmission connection between the wire winding wheel 32 and the respective wire feeding wheel by engaging or disengaging the connection between the drive gear 35 and the first gear 36 and/or the second gear 37, as shown in fig. 11. Specifically, in the first example, the clutch transmission mechanism only engages or disengages the connection between the driving gear 35 and the first gear 36, and realizes the transmission connection or disconnection between the wire winding wheel 32 and the first wire feeding wheel 33; in the second example, the clutch transmission mechanism only engages or disengages the connection between the driving gear 35 and the second gear 37, and realizes the transmission connection or disconnection between the wire winding wheel 32 and the second wire feeding wheel 34; in the third example, the clutch transmission mechanism simultaneously engages or disengages the connection between the drive gear 35 and the first gear 36 and the second gear 37, and realizes the transmission connection or disconnection of the wire winding wheel 32 and the first wire feeding wheel 33 and the second wire feeding wheel 34.

In the above technical scheme, the utility model discloses a gear is established to fixed ground cover on the shaft of rolling up wire wheel 32 and each wire feeding wheel, then through the connection between the corresponding gear of gear drive mechanism joint or disconnection to can realize the purpose that the transmission is connected between joint or disconnection wire rolling wheel 32 and the corresponding wire feeding wheel. The precision of gear transmission is high, and slipping in the transmission process can be effectively prevented.

The clutch transmission mechanism described above may engage or disengage only the connection between the drive gear 35 and the first gear 36 (i.e., the first example described above), may engage or disengage only the connection between the drive gear 35 and the second gear 37 (i.e., the second example described above), or may simultaneously engage or disengage the connection between the drive gear 35 and the first gear 36 and the second gear 37 (i.e., the third example described above). The structure of the first example is specifically described below, and the structure of other examples may refer to the arrangement of the related structure in the first example, which is not described again specifically here.

In the first example described above, the clutch transmission mechanism engages or disengages only the connection between the drive gear 35 and the first gear 36. Specifically, as shown in fig. 14 and 15, the clutch transmission mechanism in this example may include a slider 311 and a transmission gear 38, the transmission gear 38 may be rotatably disposed on the slider 311, for example, the transmission gear 38 may be mounted on the slider 311 through a wheel axle so as to be rotatable on the slider 311 around its wheel axle. The slider 311 is disposed on the mounting plate 31. Wherein the slider 311 is movable to a first position and a second position relative to the mounting plate 31. As shown in fig. 9 and 10, the slide block 311 moves to the first position during wire feeding, so that the transmission gear 38 is engaged between the driving gear 35 and the first gear 36, at this time, the driving gear 35 can drive the first gear 36 to rotate through the transmission gear 38, so that the transmission connection between the wire winding wheel 32 and the first wire feeding wheel 33 can be realized, and further, the first wire feeding wheel 33 and the second wire feeding wheel 34 are rotationally matched to drive the locking wire 3 to advance. Preferably, the first gear 36 is a driving gear, the second gear 37 is a driven gear, and the first gear 36 is engaged with the second gear 37, so that the first gear 36 is driven to drive the second gear 37 to rotate synchronously, so that both the first wire feeding wheel 33 and the second wire feeding wheel 34 can be driven to rotate synchronously, and compared with the case that only a single wire feeding wheel is driven, such as only the first wire feeding wheel 33 is driven, the manner that both the wire feeding wheels are driven makes the force for clamping the lock wire 3 larger and the wire feeding easier. As shown in fig. 12 and 13, the slider 311 moves to the second position during the wire winding process, so that the transmission gear 38 is disengaged from the first gear 36 and/or the driving gear 35, and the connection between the driving gear 35 and the first gear 36 is disconnected.

In the above example, the clutch transmission mechanism drives the transmission gear 38 to move to different positions through the slider 311, and the purpose of connecting or disconnecting the driving gear 35 and the first gear 36 can be achieved.

In order to improve the movement accuracy of the slider 311, it is preferable that the mounting plate 31 is provided with a limiting structure for limiting the slider 311 so as to move the slider 311 to the first position and the second position. In a specific application example, as shown in fig. 15, the limiting mechanism may include a sliding groove 312 disposed on the mounting plate 31 to limit the sliding block 311 through the sliding groove 312, so that the sliding block 311 reaches one end of the sliding groove 312 when moving to the first position and reaches the other end of the sliding groove 312 when moving to the second position. The movement of the sliding block 311 is limited by the sliding groove 312, and the structure is relatively simple and convenient to process.

Further, as shown in fig. 11, the aforementioned transmission gear 38 is engaged with the driving gear 35, and the driving gear 35 is used for driving the sliding block 311 to move to the first position through the transmission gear 38 in the forward rotation and driving the sliding block 311 to move to the second position through the transmission gear 38 in the reverse rotation. In this example, it is not necessary to separately provide a driving mechanism to drive the slider 311 to move, and the slider 311 is moved to the first position or the second position only by the rotation of the driving gear 35, thereby saving the cost. In addition, when the driving gear 35 rotates forward, the driving gear 35 drives the wire winding wheel 32 to pay off the sealing wire 3, and at this time, the sliding block 311 moves to the first position to drive the first wire feeding wheel 33 to rotate, so that the first wire feeding wheel 33 and the second wire feeding wheel 34 are in rotating fit to feed the sealing wire 3, and thus the wire unwinding of the wire winding wheel 32 can be performed synchronously with the wire feeding of the two wire feeding wheels, and the wire feeding is smoother.

As shown in fig. 11, the aforementioned driving mechanism may include a motor, and the motor is now named as a second motor 310 in order to distinguish it from the aforementioned motor. The second motor 310 is used for driving the driving gear 35 to rotate, so as to drive the wire winding wheel 32 to rotate through the driving gear 35. Wherein the second motor 310 rotates at a faster speed and is not generally directly connected to the driving gear 35. Preferably, the output shaft of the second motor 310 is fixedly sleeved with a third gear 39, the third gear 39 is meshed with the driving gear 35, the outer diameter of the third gear 39 is smaller than that of the driving gear 35, and the third gear 39 and the driving gear 35 are matched to form a speed reduction mechanism, so that the effect of reducing the speed of the second motor 310 can be achieved.

Further, the wire take-up and feeding mechanism may further include a clamping force adjusting mechanism, and the clamping force adjusting mechanism is configured to adjust the magnitude of the clamping force of the first wire feeding wheel 33 and the second wire feeding wheel 34 for clamping the lock wire 3, so that the clamping force of the two wire feeding wheels for clamping the lock wire 3 is not too large to damage the lock wire 3, and the clamping force is not too small to cause the friction force between the two wire feeding wheels and the lock wire 3 to be insufficient for wire feeding.

In order to achieve the function of the aforementioned clamping force adjusting mechanism, as shown in fig. 12, the clamping force adjusting mechanism may include a swing arm 313, an elastic member, and a second screw 314. To distinguish from the aforementioned elastic members, the elastic member herein is now named as a third elastic member 315. The second screw 314 is used for screwing on the mounting plate 31, and of course, the second screw 314 may be directly screwed on the mounting plate 31 or, as the case may be, screwed on an intermediate fixing member 316 fixed to the mounting plate 31 to be indirectly screwed on the mounting plate 31 through the intermediate fixing member 316. The swing arm 313 is hinged to the mounting plate 31 such that the swing arm 313 can rotate relative to the mounting plate 31. The swing arm 313 is provided with a through hole 3131, and the second screw 314 is screwed to the mounting plate 31 through the through hole 3131. The aforementioned first wire feeding wheel 33 or second wire feeding wheel 34 is provided on the swing arm 313. Preferably, the second feed wheel 34 is arranged on the swing arm 313. The third elastic member 315 may be a spring or a silicone member. The third elastic element 315 is disposed on the screw of the second screw 314 and between the nut of the second screw 314 and the swing arm 313. The third elastic member 315 is used to apply a force to the swing arm 313 so that the swing arm 313 has a tendency to bring the wire feeding wheel thereon relatively close to the other wire feeding wheel. Specifically, the swing arm 313 corresponds to a lever, and when the second screw 314 is screwed, the nut of the second screw 314 presses the third elastic member 315, so that the third elastic member 315 can apply different forces to the swing arm 313, and the force with which the locking wire 3 is clamped by the first wire feeding wheel 33 and the second wire feeding wheel 34 can be adjusted.

As shown in fig. 17 and 18, the aforementioned filament winding wheel 32 has an outer ring 201 and an inner ring 202. As shown in fig. 17, the inner ring 202 of the wire winding wheel 32 is provided with a cut-out groove 205, the cut-out groove 205 extends from one side of the inner ring 202 to the middle portion in the axial direction, and the wire winding wheel 32 is further provided with a wire passing hole 203 penetrating from the outer ring 201 to the cut-out groove 205. One end of the locking wire passes through the wire passing hole 203 into the notch groove 205, and then a second screw 314 (shown in fig. 9) can press and fix the end of the locking wire in the notch groove 205 through a nut, so as to facilitate the wire winding wheel 32 to take up and deliver the locking wire. When the locking wire penetrates through the wire hole 203 from the outer ring 201, the corners of the locking wire and the outer ring are easily abraded, and the service life of the locking wire is influenced. Therefore, as shown in fig. 18 and 19, the wire passing hole 203 and the bottom surface of the outer ring 201 are preferably smoothly transited, for example, they may be transited by a circular arc or a curved surface. Further, the wire passing hole 203 is an arc-shaped hole to further reduce stress concentration on the locking wire and prolong the service life of the locking wire.

As shown in fig. 20 and 21, the aforementioned bottom plate 1 may be made of a metal material, such as stainless steel, which has a combination of aesthetic, tough and stable properties. The rising board 1 includes a board body 41, and the rising needles 2 are integrally formed at one end of the board body 41. The head of each base needle 2 is welded and fixed with a pinhole tube section 42 (shown in fig. 21) with a pinhole 20, wherein the pinholes 20 of two adjacent pinhole tube sections 42 are opposite.

Since the plurality of the lift pins 2 are integrally formed on the plate body 41, the plate body 41 can be integrally processed by wire cutting or milling, so that the heights of the plurality of the lift pins 2 can be kept consistent, and the fluctuation and dislocation of the needle holes 20 on the heads of the plurality of the lift pins 2 in the height direction (i.e., the vertical direction in fig. 20) can be reduced.

Here, it should be noted that: although the pin holes 20 may fluctuate and be dislocated in the height direction in the process of welding the pin hole pipe sections 42, compared with the dislocation caused by manual insertion of the base pins 2, the dislocation amplitude of the pin holes 20 in the height direction caused by welding is small, so that the penetrating motion of the blocking wire 3 is not hindered in actual operation, and the tiny dislocation can be ignored.

As shown in fig. 21, the plate body 41 may further include a locking wire guide hole 431. The locking wire guide hole 431 has a locking wire inlet at one end and a locking wire outlet at the other end. The locking wire outlet is opposite to the pinhole 20 of the outermost pinhole tube section 42 in each pinhole tube section 42. The sealing wire guide hole 431 can guide the sealing wire 3, the sealing wire 3 moves along the sealing wire guide hole 431 and can be smoothly inserted into the needle hole 20 of the outermost needle hole pipe section 42, the needle hole 20 on the outermost needle hole pipe section 42 is the starting needle hole, and therefore the accuracy of inserting the sealing wire 3 into the starting needle hole 20 can be improved through the guiding of the sealing wire guide hole 431.

As shown in fig. 20, the locking wire guide hole 431 may extend from the one end of the plate body 41 to the adjacent other end, and may be transited by a circular arc at a corner between the one end and the other end. In a specific application example, the plate body 41 may have a rectangular shape, the base pins 2 are located at one end of the plate body 41 in the width direction (in some applications, the width direction may also be referred to as the height direction), and are sequentially arranged at intervals along the length direction of the plate body 41, and the locking wire guide holes 431 extend from one end of the plate body 41 in the width direction to an adjacent end of the plate body in the length direction, so that the locking wire 3 can be fed from the other end of the plate body 41.

The head surface of the pinhole pipe 42 may be a smooth surface such as a curved surface with a small top and a large bottom (as shown in fig. 22) or an arc surface (as shown in fig. 23), which is beneficial to reducing the contact resistance between the knitting yarn and the head of the pinhole pipe 42 and preventing the knitting yarn from being snapped by being stuck between two adjacent ground raising needles 2.

Further, as shown in fig. 24 and 25, the plate body 41 may be provided with a reinforcing rib 45 to improve the structural strength of the plate body 41. The reinforcing rib 45 may be a part of the plate body 41 integrally formed with the plate body 41 (as shown in fig. 24), or may be fixed to the plate body 41 by external connection (as shown in fig. 25). The following two cases are described: in a first example, as shown in fig. 24, the reinforcing rib 45 is a part of the plate body 41, and the reinforcing rib 45 may be formed by bending one end of the plate body 41 opposite to the base lifting pin 2, so that the reinforcing rib 45 and the plate body 41 have good connection stability and cannot be loosened; in addition, the overall flatness of the plate body 41 is also well ensured. Preferably, the reinforcing rib 45 is a "mouth" shaped structure bent from the end of the plate body 41 opposite to the base pin 2. In a second example, as shown in fig. 25, the reinforcing rib 45 may be a reinforcing plate, and the reinforcing plate is fixed to the plate body 41 by a fourth screw 46. Preferably, the reinforcing plate may be L-shaped and fixed to an end of the plate body 41 opposite to the base pin 2, which has an advantage of convenient processing.

The embodiment of the utility model provides a processing technology of rising bottom plate still is provided, its rising bottom plate 1 that is arranged in processing above-mentioned arbitrary example. As shown in fig. 26, the processing technology of the starting plate 1 includes the following steps:

step S: and obtaining the metal plate body. The metal plate body can be made of stainless steel, and the stainless steel has comprehensive practical performances of beauty, toughness, stability and the like. The metal plate body may have been machined beforehand to have the profile of the aforementioned plate body 41.

Step S: and welding a metal pinhole tube at one end of the metal plate body along the contour line to obtain an intermediate assembly. Wherein, the pinhole pipe can be a seamless steel pipe.

Step S: a plurality of cutting grooves 44 are formed at intervals in sequence at the end of the pinhole pipe of the intermediate assembly, wherein the pinhole pipe is provided with straight line sections, and each cutting groove 44 is distributed along the axial direction on the straight line sections and extends towards the inner part of the metal plate body so as to form the priming needle 2 with the pinhole pipe section 42 at the head part between two adjacent cutting grooves 44.

Wherein, the intensity of metal pinhole pipe is better, can guarantee that the straightness accuracy of its straightway is not influenced when whole welding, then when interval processing grooving 44 on the straightway of pinhole pipe, can guarantee that the pinhole 20 of two adjacent pinhole pipeline sections 42 is relative, and the concentricity of the pinhole 20 of two adjacent pinhole pipeline sections 42 is better, make blockade silk 3 can smoothly pass each pinhole 20 in proper order, effectively improved the dislocation that current rising end needle 2 mosaic welding alone caused on the height, improved the machining precision of rising end plate 1.

Further, as shown in fig. 20 and 21, the aforementioned needle bore tube may have another section 43 of the needle bore tube connected to a straight section to form a locking wire guide hole 431 inside the other section 43 of the needle bore tube. The other segment 43 may be a straight segment, an arc segment, or a combination of a straight segment and an arc segment. In this example, since the locking wire guide hole 431 is formed directly inside another section of the tube of the pinhole 20, there is an advantage in that the locking wire guide hole 431 can be easily processed.
