DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in the following with reference to the drawings in the embodiments of the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor based on the embodiments in the utility model belong to the range protected by the utility model.

[0035] Please refer to Figure 1 ~ to Figure 6 The needle selection seat structure of the needle selector comprises a plurality of magnetic rod assemblies 1 and a mounting seat 2 for mounting the plurality of magnetic rod assemblies 1, and the plurality of magnetic rod assemblies 1 are arranged in a staggered manner on the mounting seat 2; the magnetic rod assembly 1 comprises a first magnetic rod 11 and a second magnetic rod 12 arranged at intervals, a first coil 13 arranged on the first magnetic rod 11, and a second coil 14 arranged on the second magnetic rod 12, the top end of the first magnetic rod 11 is N-pole after magnetization, the top end of the second magnetic rod 12 is S-pole after magnetization, the current directions of the first coil 13 and the second coil 14 are opposite, the first coil 13 is de-magnetized to the first magnetic rod 11, and the second coil 14 is de-magnetized to the second magnetic rod 12.

[0036] In the present application, the needle selection seat structure comprises the mounting seat 2 and the plurality of magnetic rod assemblies 1, and the plurality of magnetic rod assemblies 1 are mounted on the mounting seat 2. It can be foreseen that the number of the magnetic rod assemblies 1 corresponds to the number of the spring needles. Since the plurality of magnetic rod assemblies 1 are arranged in a staggered manner on the mounting seat 2, the corresponding spring needle can be adsorbed or released by a single magnetic rod assembly 1, so that the needle selection of the needle selector can be realized.

[0037] In the present application, the magnetic rod assembly 1 comprises the first magnetic rod 11 and the second magnetic rod 12, and the first magnetic rod 11 and the second magnetic rod 12 are arranged at intervals, wherein the top end of the first magnetic rod 11 is N-pole after magnetization, and the top end of the second magnetic rod 12 is S-pole after magnetization. For a single spring needle, the magnetic attraction force generated by the first magnetic rod 11 and the second magnetic rod 12 can simultaneously adsorb the corresponding spring needle.

[0038] Since the direction of the magnetic induction line of the magnet is from N-pole to S-pole outside the magnet and from S-pole to N-pole inside the magnet, in the prior art, the magnetic rod of the needle selector for a single spring needle is of the same magnetic pole. Therefore, outside the magnetic rod, the magnetic induction line is propagated from N-pole to S-pole in the air, the loop of the magnetic induction line propagated in the air is scattered, and the energy loss is large, so that the magnetic field of the magnetic rod is easily interfered with the magnetic field of the surrounding magnetic rod, the adsorption force of the magnetic rod to the corresponding spring needle is reduced, and the needle selection error is likely to occur, the weaving error is caused, and the production efficiency is affected.

[0039] In the present application, the first magnetic rod 11 is magnetized to have a N-pole at the top end, and the second magnetic rod 12 is magnetized to have a S-pole at the top end. When the first magnetic rod 11 and the second magnetic rod 12 simultaneously attract the corresponding spring needle, the spring needle connects the top end of the first magnetic rod 11 and the top end of the second magnetic rod 12.

[0040] In the present embodiment, the first magnetic rod 11, the second magnetic rod 12 and the spring needle are all made of soft magnetic material. Since air is a non-magnetic medium, its magnetic resistance is much larger than that of soft magnetic material. Similarly to electric current, magnetic induction lines always take the path with the smallest magnetic resistance (the largest magnetic permeability). Therefore, outside the first magnetic rod 11 and the second magnetic rod 12, most of the magnetic induction lines are propagated from the N-pole to the S-pole in the spring needle.

[0041] On the one hand, the magnetic induction line loop outside the first magnetic rod 11 and the second magnetic rod 12 is prevented from being scattered, thereby reducing the magnetic field interference with the surrounding magnetic rod assembly 1. On the other hand, since the magnetic resistance of the spring needle is much smaller than that of air, the energy loss of the magnetic induction lines in the spring needle is small, thereby enhancing the attraction force of the first magnetic rod 11 and the second magnetic rod 12 to the corresponding spring needle, and further ensuring the accuracy of needle selection and improving the production efficiency.

[0042] In the present application, the magnetic rod assembly 1 further comprises a first coil 13 and a second coil 14. The first coil 13 is arranged on the first magnetic rod 11, and the second coil 14 is arranged on the second magnetic rod 12. As mentioned above, the first magnetic rod 11 and the second magnetic rod 12 are made of soft magnetic material. Therefore, after the first magnetic rod 11 and the second magnetic rod 12 are magnetized, they can simultaneously generate magnetic attraction force to the corresponding spring needle, so as to elastically deform the spring needle and thereby attract the spring needle to the top end of the first magnetic rod 11 and the second magnetic rod 12.

[0043] When the first coil 13 is energized, the magnetic field formed in the first coil 13 has a magnetic induction line direction opposite to that of the internal magnetic induction line of the first magnetic rod 11 after magnetization. Therefore, the magnetic field formed in the first coil 13 and the magnetic field of the first magnetic rod 11 after magnetization offset each other, thereby reducing the magnetic field strength of the first magnetic rod 11 and realizing the demagnetization of the first magnetic rod 11.

[0044] When the second coil 14 is energized, the magnetic field formed in the second coil 14 has a magnetic induction line direction opposite to that of the internal magnetic induction line of the second magnetic rod 12 after magnetization. Therefore, the magnetic field formed in the second coil 14 and the magnetic field of the second magnetic rod 12 after magnetization offset each other, thereby reducing the magnetic field strength of the second magnetic rod 12 and realizing the demagnetization of the second magnetic rod 12.

[0045] When the magnetic attraction of the first magnetic rod 11 and the second magnetic rod 12 to the spring needle is less than the elastic force of the spring needle to restore its deformation, the first magnetic rod 11 and the second magnetic rod 12 will release the adsorbed spring needle, so that the spring needle restores to the original shape. Therefore, in the present application, the first magnetic rod 11 and the second magnetic rod 12 adsorb or release the corresponding spring needle, so that the position of the corresponding spring needle changes, thereby realizing the needle selection of the needle selector.

[0046] In one embodiment, initially, the first magnetic rod 11 and the second magnetic rod 12 do not adsorb the corresponding spring needle, at this time the spring needle is in a non-working position; when selecting a needle, the first magnetic rod 11 and the second magnetic rod 12 adsorb the corresponding spring needle, so that the spring needle moves from the non-working position to the working position and performs knitting work; after the work is completed, the first coil 13 and the second coil 14 are energized, the first magnetic rod 11 and the second magnetic rod 12 release the corresponding spring needle, so that the spring needle returns to the non-working position and waits for the next knitting work.

[0047] In another embodiment, initially, the first magnetic rod 11 and the second magnetic rod 12 adsorb the corresponding spring needle, at this time the spring needle is in a non-working position; when selecting a needle, the first coil 13 and the second coil 14 are energized, the first magnetic rod 11 and the second magnetic rod 12 release the corresponding spring needle, so that the spring needle moves from the non-working position to the working position and performs knitting work; after the work is completed, the first coil 13 and the second coil 14 are de-energized, the first magnetic rod 11 and the second magnetic rod 12 adsorb the corresponding spring needle, so that the spring needle returns to the non-working position and waits for the next knitting work.

[0048] The needle selector of the present application is suitable for flat knitting machines such as glove machines, flat machines, collar machines, etc., that is, the needle selection seat structure of the present needle selector simultaneously adsorbs or releases the corresponding spring needle of the flat knitting machines such as glove machines, flat machines, collar machines, etc., through the first magnetic rod 11 and the second magnetic rod 12, so that the needle selection of the flat knitting machines such as glove machines, flat machines, collar machines, etc. can be realized.

[0049] Further, in the present embodiment, the magnetic rod assembly 1 further comprises a magnetic rod base 15 and a permanent magnet 16, the permanent magnet 16 is arranged in the magnetic rod base 15, the first magnetic rod 11 and the second magnetic rod 12 are arranged on the magnetic rod base 15 in a spaced manner, and the permanent magnet 16 is arranged between the first magnetic rod 11 and the second magnetic rod 12.

[0050] Since the bottom end of the first magnetic rod 11 is attached to the N pole of the permanent magnet 16 and the bottom end of the second magnetic rod 12 is attached to the S pole of the permanent magnet 16, the first magnetic rod 11 and the second magnetic rod 12 are magnetized by the permanent magnet 16, and the top end of the first magnetic rod 11 is N pole and the top end of the second magnetic rod 12 is S pole, so that the corresponding spring needle is adsorbed by the magnetic attraction generated by the first magnetic rod 11 and the second magnetic rod 12.

[0051] After the first magnetic rod 11 and the second magnetic rod 12 are magnetized by the permanent magnet 16, the first magnetic rod 11 extends to the N pole of the permanent magnet 16, and the second magnetic rod 12 extends to the S pole of the permanent magnet 16, that is, the first magnetic rod 11, the permanent magnet 16 and the second magnetic rod 12 are regarded as a whole magnet, the first magnetic rod 11 is the N pole of the magnet, and the second magnetic rod 12 is the S pole of the magnet.

[0052] The magnetic induction line direction of the magnet is from the N pole to the S pole outside the magnet, that is, outside the magnet, the magnetic induction line is propagated from the top end of the first magnetic rod 11 to the top end of the second magnetic rod 12 in the air. When the first magnetic rod 11 and the second magnetic rod 12 are attracted to the spring needle, the spring needle connects the top end of the first magnetic rod 11 and the top end of the second magnetic rod 12, that is, the spring needle connects the N pole and the S pole of the whole magnet.

[0053] Because the magnetic resistance of the spring needle is much smaller than that of the air, the magnetic induction line outside the magnet preferentially selects the path with the smallest magnetic resistance, so most of the magnetic induction line is propagated from the N pole to the S pole in the spring needle, thereby preventing the magnetic induction line loop outside the magnet from being scattered and reducing the mutual interference with the surrounding magnetic field, reducing the energy loss of the magnetic induction line, enhancing the attraction of the first magnetic rod 11 and the second magnetic rod 12 to the spring needle, and further ensuring the accuracy of needle selection and improving production efficiency.

[0054] Further, in the embodiment, the magnetic rod base 15 is provided with a first fixing cavity 151, a second fixing cavity 152 and a third fixing cavity 153, the first fixing cavity 151 is arranged in a spaced manner with the second fixing cavity 152, and the third fixing cavity 153 is arranged between the first fixing cavity 151 and the second fixing cavity 152.

[0055] When assembling the magnetic rod assembly 1, the bottom of the first magnetic rod 11 is inserted into the first fixing cavity 151, the bottom of the second magnetic rod 12 is inserted into the second fixing cavity 152, and the permanent magnet 16 is arranged in the third fixing cavity 153, so that the first magnetic rod 11 is fixed by the first fixing cavity 151, the second magnetic rod 12 is fixed by the second fixing cavity 152, and the permanent magnet 16 is fixed by the third fixing cavity 153, so that the first magnetic rod 11 and the second magnetic rod 12 are arranged in a spaced manner on the magnetic rod base 15, and the permanent magnet 16 is arranged between the first magnetic rod 11 and the second magnetic rod 12.

[0056] Because the two ends of the third fixing cavity 153 are communicated with the first fixing cavity 151 and the second fixing cavity 152 respectively, the N pole and the S pole of the permanent magnet 16 are located at the two ends of the permanent magnet 16, so that the N pole of the permanent magnet 16 is attached to the bottom end of the first magnetic rod 11 at one end of the third fixing cavity 153, and the S pole of the permanent magnet 16 is attached to the bottom end of the second magnetic rod 12 at the other end of the third fixing cavity 153, so that the first magnetic rod 11, the permanent magnet 16 and the second magnetic rod 12 form a U-shaped whole magnet.

[0057] In the foregoing embodiment, it is mentioned that the magnetic flux lines of the whole magnet formed by the permanent magnet 16, the first magnetic rod 11 and the second magnetic rod 12 are propagated from the top end of the first magnetic rod 11 to the top end of the second magnetic rod 12 outside the whole magnet, and the magnetic flux lines of the inside of the whole magnet are propagated from the top end of the second magnetic rod 12 to the top end of the first magnetic rod 11 after sequentially passing through the second magnetic rod 12, the permanent magnet 16 and the first magnetic rod 11, thereby forming a closed loop with the magnetic flux lines outside the whole magnet.

[0058] Therefore, in the present application, the internal magnetic flux lines of the first magnetic rod 11 after magnetization are propagated from the bottom end to the top end of the first magnetic rod 11, and the internal magnetic flux lines of the second magnetic rod 12 after magnetization are propagated from the top end to the bottom end of the second magnetic rod 12, that is, the internal magnetic flux lines of the first magnetic rod 11 after magnetization are from bottom to top, and the internal magnetic flux lines of the second magnetic rod 12 after magnetization are from top to bottom.

[0059] Therefore, in the present embodiment, the first coil 13 is wound around the outer periphery of the first magnetic rod 11 from bottom to top, so that when the first coil 13 is energized, the magnetic field formed in the first coil 13 has a direction opposite to that of the internal magnetic flux lines of the first magnetic rod 11 after magnetization, thereby causing the magnetic field formed in the first coil 13 to cancel the magnetic field of the first magnetic rod 11 after magnetization, reducing the magnetic field strength of the first magnetic rod 11, and further realizing demagnetization of the first magnetic rod 11.

[0060] The second coil 14 is wound around the outer periphery of the second magnetic rod 12 from top to bottom, so that when the second coil 14 is energized, the magnetic field formed by the second coil 14 has a direction opposite to that of the internal magnetic flux lines of the second magnetic rod 12 after magnetization, thereby causing the magnetic field formed by the second coil 14 to cancel the magnetic field of the second magnetic rod 12 after magnetization, reducing the magnetic field strength of the second magnetic rod 12, and further realizing demagnetization of the second magnetic rod 12.

[0061] In actual implementation, the first coil 13 and the second coil 14 can be energized by the same power supply device, or can be energized by two separate power supply devices. In order to make the structure of the needle selector more compact and reduce production cost, in the present application, the first coil 13 and the second coil 14 are preferably energized by the same power supply device.

[0062] Therefore, in the present embodiment, the tail end of the first coil 13 is connected to the head end of the second coil 14, thereby connecting the first coil 13 and the second coil 14 in series; the head end of the first coil 13 is connected to the positive pole of the power supply circuit, and the tail end of the second coil 14 is connected to the negative pole of the power supply circuit, thereby forming a closed loop, so that the power supply circuit can simultaneously energize the first coil 13 and the second coil 14, thereby making the structure of the needle selector more compact and reducing production cost.

[0063] Specifically, in actual implementation, the same enameled wire can be used to make the first coil 13 and the second coil 14 and to connect the first coil 13 and the second coil 14 in series. That is, the enameled wire is first wound in a spiral shape from bottom to top around the outer periphery of the first magnetic rod 11 to form the first coil 13. Then, the enameled wire is pulled horizontally to the second magnetic rod 12 at the top of the first coil 13 and wound in a spiral shape from top to bottom around the outer periphery of the second magnetic rod 12 to form the second coil 14, thereby realizing the connection of the first coil 13 and the second coil 14 in series. Finally, the leading end of the enameled wire is connected to the positive pole of the power supply circuit, and the trailing end of the enameled wire is connected to the negative pole of the power supply circuit, thereby forming a closed loop and enabling the power supply circuit to pass current through the first coil 13 and the second coil 14 at the same time.

[0064] Since the leading end of the first coil 13 is located at the bottom of the first coil 13, and the trailing end of the second coil 14 is located at the bottom of the second coil 14, it is easier to connect the leading end of the first coil 13 to the positive pole of the power supply circuit and the trailing end of the second coil 14 to the negative pole of the power supply circuit, thereby making the implementation of the magnetic rod assembly 1 simpler and more convenient and further improving production efficiency.

[0065] In addition, since the trailing end of the first coil 13 is located at the top of the first coil 13, and the leading end of the second coil 14 is located at the top of the second coil 14, the connection of the first coil 13 and the second coil 14 in series at the top of the first coil 13 and the top of the second coil 14 can not only reduce the use of enameled wire and thus reduce production costs, but also make the connection of the first coil 13 and the second coil 14 in series simpler, thereby making the implementation of the magnetic rod assembly 1 simpler and more convenient and improving production efficiency.

[0066] Since the magnetic field formed in the current-carrying coil is related to the direction of the current in the current-carrying coil, in actual implementation, it is worth noting that when the first coil 13 is wound around the outer periphery of the first magnetic rod 11 from bottom to top, and the second coil 14 is wound around the outer periphery of the second magnetic rod 12 from top to bottom, the direction of the current in the first coil 13 and the second coil 14 should be designed according to the right-hand screw rule, so that the magnetic field formed in the first coil 13 and the second coil 14 has the above-mentioned direction of magnetic induction lines.

[0067] In this embodiment, the trailing end of the second coil 14 extends to the side where the leading end of the first coil 13 is located. Specifically, the enameled wire is first wound in a spiral shape from bottom to top around the outer periphery of the first magnetic rod 11 to form the first coil 13. Then, the enameled wire is pulled horizontally to the second magnetic rod 12 at the top of the first coil 13 and wound in a spiral shape from top to bottom around the outer periphery of the first coil 13 to form the second coil 14, thereby realizing the connection of the first coil 13 and the second coil 14 in series.

[0068] Finally, the bottom of the formed second coil 14, the strip of enameled wire is horizontally pulled to the first magnetic bar 11, so that the tail end of the strip of enameled wire is located on the same side as the head end, and thus the head end of the strip of enameled wire is connected to the positive pole of the power supply circuit on the same side, and the tail end is connected to the negative pole of the power supply circuit, which can make the connection of the strip of enameled wire and the power supply circuit more simple and convenient, easy to implement, and the wiring of the power supply circuit more regular, thereby making the implementation of the magnetic bar assembly 1 more simple and convenient, and further improving the production efficiency.

[0069] Further, in the present embodiment, one side of the magnetic bar base 15 is provided with a wiring slot 154, when the tail end of the second coil 14 extends to the side where the head end of the first coil 13 is located, the head end of the first coil 13 and the tail end of the second coil 14 are both wired from the wiring slot 154, and the head end of the first coil 13 and the tail end of the second coil 14 are limited by the wiring slot 154, thereby making the wiring of the first coil 13 and the second coil 14 more regular, further making the implementation of the magnetic bar assembly 1 more simple and convenient, and improving the production efficiency.

[0070] In the present embodiment, the mounting seat 2 is provided with a containing cavity for containing a plurality of magnetic bar assemblies 1. A plurality of magnetic bar outlets 211 are provided at the top of the containing cavity, and a plurality of magnetic bar positioning grooves 212 are provided at the bottom of the containing cavity, which limit the bottoms of the plurality of magnetic bar assemblies 1 respectively, and the tops of the plurality of magnetic bar assemblies 1 respectively extend out of the plurality of magnetic bar outlets 211, so that the tops of the plurality of magnetic bar assemblies 1 can adsorb or release the corresponding pogo pins, thereby realizing the selection of the pogo pin selector.

[0071] Specifically, in actual implementation, each magnetic bar positioning groove 212 limits the magnetic bar base 15 of one magnetic bar assembly 1, and the tops of the first magnetic bar 11 and the second magnetic bar 12 of each magnetic bar assembly 1 extend out of one magnetic bar outlet 211, so that the tops of the first magnetic bar 11 and the second magnetic bar 12 can simultaneously adsorb or release the corresponding pogo pins.

[0072] In the present embodiment, the mounting seat 2 is composed of a first seat body 21 and a second seat body 22. The first seat body 21 is provided with a first half cavity, and the second seat body 22 is provided with a second half cavity, and when the first seat body 21 and the second seat body 22 are combined, the first half cavity and the second half cavity are combined into a complete containing cavity.

[0073] In the application, according to the number and position of the spring pins, the plurality of magnetic rod assemblies 1 are arranged in at least two rows on the mounting seat 2, and the plurality of magnetic rod assemblies 1 arranged in the adjacent two rows are arranged in turn staggered, so that the plurality of magnetic rod assemblies 1 can adsorb or release the respective corresponding spring pins, and in the process of adsorbing or releasing the respective corresponding spring pins by the plurality of magnetic rod assemblies 1, the movement trajectories of all the spring pins do not coincide, thereby preventing mutual interference between the spring pins, and further ensuring the accuracy of needle selection and improving the production efficiency.

[0074] Specifically, in actual implementation, at least one row of magnetic rod assemblies 1 is arranged in the first half cavity, and at least one row of magnetic rod assemblies 1 is arranged in the second half cavity. Taking the example of arranging two rows of staggered magnetic rod assemblies 1 on the mounting seat 2, that is, arranging the first row of magnetic rod assemblies 1 in the first half cavity and the second row of magnetic rod assemblies 1 in the second half cavity.

[0075] Therefore, in the embodiment, the bottom of the first half cavity and the bottom of the second half cavity are both provided with a plurality of magnetic rod positioning grooves 212. The plurality of magnetic rod positioning grooves 212 arranged at the bottom of the first half cavity are used to limit the bottom of the first row of magnetic rod assemblies 1 respectively, and the plurality of magnetic rod positioning grooves 212 arranged at the bottom of the second half cavity are used to limit the bottom of the second row of magnetic rod assemblies 1 respectively.

[0076] The top of the first half cavity and the top of the second half cavity are both provided with a plurality of magnetic rod exit ports 211, the top of the first row of magnetic rod assemblies 1 respectively extends from the plurality of magnetic rod exit ports 211 arranged at the top of the first half cavity, and the top of the second row of magnetic rod assemblies 1 respectively extends from the plurality of magnetic rod exit ports 211 arranged at the top of the second half cavity.

[0077] In the application, the plurality of magnetic rod positioning grooves 212 arranged at the bottom of the first half cavity are arranged in a staggered manner with the plurality of magnetic rod positioning grooves 212 arranged at the bottom of the second half cavity, and the plurality of magnetic rod exit ports 211 arranged at the top of the first half cavity are arranged in a staggered manner with the plurality of magnetic rod exit ports 211 arranged at the top of the second half cavity, so that the first row of magnetic rod assemblies 1 arranged in the first half cavity are arranged in a staggered manner with the second row of magnetic rod assemblies 1 arranged in the second half cavity.

[0078] Further, in the embodiment, one end of the plurality of magnetic rod extension outlets 211 arranged at the top of the first half cavity and the second half cavity is open, and one end of the plurality of magnetic rod positioning grooves 212 arranged at the bottom of the first half cavity and the second half cavity is open. When the installation of the first row of magnetic rod assemblies 1 in the first seat body 21 and the installation of the second row of magnetic rod assemblies 1 in the second seat body 22 are performed, the top of the magnetic rod assembly 1 is inserted and connected in the magnetic rod extension outlet 211 through the opening of the magnetic rod extension outlet 211, and the bottom of the magnetic rod assembly 1 is inserted and connected in the magnetic rod positioning groove 212 through the opening of the magnetic rod positioning groove 212, so that the installation of the first row of magnetic rod assemblies 1 in the first seat body 21 and the installation of the second row of magnetic rod assemblies 1 in the second seat body 22 are more simple and convenient, and the implementation of the needle selection seat structure is more simple and convenient.

[0079] In the foregoing embodiment, it is mentioned that the first coil 13 and the second coil 14 of each magnetic rod assembly 1 are routed from the wire slot 154 on one side of the magnetic rod base 15, and the first coil 13 and the second coil 14 are limited in the wire slot 154, so that the wire routing of the first coil 13 and the second coil 14 is more regular.

[0080] Therefore, in the embodiment, the bottom of each magnetic rod positioning groove 212 is provided with a wire hole 213, and the bottom of the mounting seat 2 is provided with a control panel 3. When the magnetic rod base 15 of the magnetic rod assembly 1 is inserted into the magnetic rod positioning groove 212, the first end of the first coil 13 and the tail end of the second coil 14 routed through the wire slot 154 are fixedly connected with the control panel 3 after penetrating through the wire hole 213, so that the first end of the first coil 13 and the tail end of the second coil 14 of all the magnetic rod assemblies 1 are integrated on the control panel 3, and finally connected with the positive and negative poles of the power supply circuit through the control panel 3, thereby making the wire routing of the needle selection seat structure more simple and facilitating the implementation of the needle selection seat structure.

[0081] Further, in the embodiment, the needle selection seat structure further comprises a shell 4, and the mounting seat 2 is arranged at the top of the shell 4 and fixedly connected with the shell 4, so that the mounting seat 2 is fixed by the shell 4. Since the control panel 3 is arranged at the bottom of the mounting seat 2, when the mounting seat 2 is fixedly installed at the top of the shell 4, the control panel 3 is located in the cavity of the shell 4, so that the control panel 3 is protected by the shell 4, preventing the control panel 3 from being exposed, and enhancing the safety of the needle selector.
