Specific implementation
[0042] For the convenience of understanding of those skilled in the art, the utility model is further described below in combination with the embodiments and the drawings, and the content mentioned in the embodiments is not a limitation on the utility model.
[0043] Embodiment one
[0044] As Figure 1 shown, the embodiment provides a pencil core tool, the pencil core tool 10 is suitable for a mechanical pencil, the pencil core tool 10 includes a pencil core part 11 and an acting part 12 arranged at one end of the pencil core part 11, and the pencil core part 11 can be inserted into the inner core of the external mechanical pencil. Specifically, the pencil core tool 10 is made of a metal material. The shape of the pencil core part 11 of the pencil core tool 10 is the same as the shape of the pencil core of the mechanical pencil in the prior art, and both are slender straight rod-shaped, the cross section of the pencil core part 11 can be circular, square or other shapes, and the diameter of the pencil core part 11 can be 0.3mm, 0.5mm, 0.7mm, 0.9mm or other sizes, as long as the cross-sectional shape and diameter size are suitable for the actual use of the mechanical pencil.
[0045] In the embodiment, by setting the pencil core tool 10 and using the pencil core tool 10 in cooperation with the widely used mechanical pencil, the mechanical pencil acts as a holding part of a hand tool, instead of the independent and bulky hand tool in the prior art, so that the volume of each hand tool is effectively reduced, and it is convenient to store and convenient for users to carry for use. In actual use, when the function of a certain hand tool is needed, such as the function of a cutter, the pencil core tool 10 with the function of the cutter is inserted into the mechanical pencil, and a cutter is formed, wherein the mechanical pencil acts as a holding part, and the user holds the mechanical pencil to operate, so that the function of the cutter is realized. When the function of other hand tools is needed, the pencil core tool 10 with the corresponding function is inserted into the mechanical pencil, and a hand tool with the corresponding function is formed. When the function of the hand tool is not needed, the pencil core tool 10 can be taken out of the mechanical pencil, and the pencil core of the mechanical pencil in the prior art is inserted into the mechanical pencil, so that the function of the pencil is realized.
[0046] Further, as Figure 1 shown, the acting part 12 is a blade part 121 or a sharp needle part 122. Among them, the blade part 121 can be provided with a blade at the top, a blade at the side or a blade at other parts. Of course, in other embodiments, the acting part 12 can also be other forms of hand tools, such as screwdrivers, wrenches, etc.
[0047] Further, as Figure 1As shown, the central axis of the functional part 12 is set at an angle to the central axis of the pencil lead-shaped part 11, and / or the cross-sectional area of the functional part 12 is larger than the cross-sectional area of the pencil lead-shaped part 11. Specifically, as Figure 1 As shown, the central axis of the blade portion 121 is set at an angle to the central axis of the pencil lead-shaped portion 11. In actual use, the pencil lead-shaped tool 10 with the blade portion 121 as its working part has two usage states. In one usage state, the pencil lead-shaped portion 11 is clamped and fixed by the claws in the external mechanical pencil lead. In this state, the pencil lead-shaped tool 10 with the blade portion 121 and the external pencil with the mechanical pencil lead combine to form a craft knife, facilitating the user's cutting of easily cut items such as origami. In the other usage state, the pencil lead-shaped portion 11 is inserted into the claws of the external mechanical pencil lead, but the claws are in an open state. When the lead-shaped part 11 is released, the lead-shaped tool 10 can rotate 360° relative to the gripper under external force. At this time, when the user holds a pen with the lead-shaped tool 10 inserted (not clamped) and strokes it across the surface of an object being cut (such as origami), the user can easily control the cutting direction of the blade 121 by controlling the direction of the force applied by the hand, thus forming any desired cutting curve on the surface of the object. Furthermore, because the central axis of the blade 121 is angled to the central axis of the lead-shaped part 11, although the lead-shaped part 11 is not clamped, the blade 121 will not retract into the mechanical pencil lead under external force. Of course, depending on the specific operation of different types of lead-shaped tools 10 in actual use, in some other embodiments, the central axis of the actuating part 12 and the central axis of the lead-shaped part 11 may also be coincident, such as... Figure 1 As shown, the central axis of the needle portion 122 coincides with the central axis of the pencil lead-shaped portion 11. Furthermore, in this embodiment, by setting the cross-sectional area of the actuating portion 12 to be larger than the cross-sectional area of the pencil lead-shaped portion 11, on the one hand, when the pencil lead-shaped tool 10 is in a state where it is not clamped by the grippers in the mechanical pencil lead, the actuating portion 12 is prevented from retracting into the mechanical pencil lead under external force; on the other hand, the strength of the actuating portion 12 can be increased, extending its service life.
[0048] Example 2
[0049] like Figures 2 to 4As shown, the automatic pencil inner core 20 of the embodiment comprises a hollow barrel 21, one end of the inside of the hollow barrel 21 is provided with an inner core tube 22, specifically, the end of the hollow barrel 21 close to the pencil tip is provided with the inner core tube 22, the outer diameter of the inner core 22 is smaller than the inner diameter of the hollow barrel 21, so that a storage cavity 212 is arranged between the inner wall of the hollow barrel 21 and the outer wall of the inner core tube 22, the storage cavity 212 is annular, and the storage cavity 212 is used for storing pencil leads and / or pencil lead-shaped tools 10 described in any one of Embodiment One; and since the length of the inner core tube 22 is smaller than the length of the hollow barrel 21, the end of the hollow barrel 21 away from the pencil tip has a larger space for accommodating the working part 12 of the pencil lead-shaped tool 10; the end of the hollow barrel 21 close to the inner core tube 22 is provided with an elastic clamping assembly, the elastic clamping assembly can adopt the elastic clamping assembly in the automatic pencil inner core in the prior art, the inner core tube 22 and the elastic clamping assembly are provided with a lead passing channel 211, and the pencil lead or the pencil lead-shaped part 11 can be inserted in the lead passing channel 211; the elastic clamping assembly can be switched between the state of clamping the pencil lead or the pencil lead-shaped tool 10 and the state of releasing the pencil lead or the pencil lead-shaped tool 10.
[0050] In the embodiment, by arranging the inner core tube 22 in the automatic pencil inner core 20, the storage cavity 212 separated from the lead passing channel 211 is formed in the automatic pencil inner core 20, the pencil lead and the pencil lead-shaped part 11 of the pencil lead-shaped tool 10 can be inserted in the storage cavity 212, so that a plurality of pencil lead-shaped tools 10 can be stored in the hollow barrel 21, which facilitates the storage of the plurality of pencil lead-shaped tools 10 and prevents loss; and the user carrying one pencil provided with the automatic pencil inner core 20 is equivalent to carrying a pencil and a plurality of hand tools, which greatly facilitates the user to carry and use. In addition, the automatic pencil inner core 20 in the embodiment can be assembled and used with most pressing pencil shells on the market, such as the shell of a pressing automatic pencil, the shell of a pressing neutral pen, etc., that is, the consumer purchases the automatic pencil inner core 20 in the embodiment, sets a second spring 36 outside the elastic clamping assembly, and assembles the automatic pencil inner core 20 and the second spring 36 into the pressing pencil shell on the market, so that a pencil is assembled and formed for use, which has strong applicability; on this basis, in order to ensure that the second spring 36 can be compressed under the pressing of an external force, the outer diameter of the hollow barrel 21 is greater than the outer diameter of the elastic clamping assembly, so that the hollow barrel 21 generates extrusion force on the second spring 36 under the action of the pressing external force, thereby driving the second spring 36 to be compressed, so that the automatic pencil inner core 20 can smoothly protrude out of the shell of the pressing pencil for use.
[0051] Further, the elastic clamping assembly comprises a clamping jaw 23, a first spring 24, a clamping ring 25, a positioning sleeve 26 and a core sleeve 27. The clamping jaw 23 is arranged at one end of the hollow core barrel 21 close to the inner core tube 22. The clamping ring 25 is movably arranged outside the clamping jaw 23. The clamping jaw 23 at the other end away from the hollow core barrel 21 and the clamping ring 25 is movably arranged inside the positioning sleeve 26. The positioning sleeve 26 is provided with a limiting part 261 at one end close to the hollow core barrel 21. The positioning sleeve 26 is provided with the core sleeve 27 at the other end away from the hollow core barrel 21. The positioning sleeve 26 is provided with a positioning step 262 at the middle position inside. The first spring 24 is arranged outside the clamping jaw 23 between the positioning sleeve 26 and the hollow core barrel 21.
[0052] In the embodiment, the specific structure of the elastic clamping assembly is specifically limited. Under the action of external force, the hollow core barrel 21 drives the clamping jaw 23 and the clamping ring 25 to move forward (toward the direction close to the pen tip). The first spring 24 is compressed. When the clamping ring moves to the position of the positioning step 262, the clamping ring 25 cannot continue to move forward with the hollow core barrel 21 and the clamping jaw 23 due to the blockage of the positioning step 262. The clamping jaw 23 is separated from the clamping ring 25. Since the matching surface between the clamping jaw 23 and the clamping ring 25 is a tapered surface, the multiple clamping jaws in the clamping jaw 23 separate from each other after the clamping jaw 23 is separated from the clamping ring 25. At this time, the state of the pencil core or the pencil core-shaped tool 10 is loosened. When the external force is removed, the first spring 24 returns, thereby driving the hollow core barrel 21 and the clamping jaw 23 to move backward (toward the direction away from the pen tip). When the clamping jaw 23 retreats into the clamping ring 25, the clamping ring 25 is driven to move backward. When the clamping ring 25 moves to the position of the limiting part 261, the clamping ring 25 stops moving, thereby limiting the clamping jaw 23 and the hollow core barrel 21 from continuing to retreat. Under the constraint of the clamping ring 25, the multiple clamping jaws in the clamping jaw 23 approach each other. At this time, the state of the pencil core or the pencil core-shaped tool 10 is clamped. Preferably, the inside of the positioning sleeve 26 is further provided with a detent ring 263. The inner hole diameter of the detent ring 263 is slightly smaller than the diameter of the pencil core and the diameter of the pencil core-shaped part 11, respectively. In the embodiment, by arranging the detent ring 263, when the pencil core-shaped tool 10 is in the state of being used without being clamped by the clamping jaw 23 in the inner core 20 of the automatic pencil, without external force, the pencil core-shaped tool 10 will not fall down due to gravity, which is convenient for use.
[0053] Further, the other end of the hollow core barrel 21 away from the inner core tube 22 is detachably provided with a tail plug 28. In the embodiment, the tail plug 28 is arranged to prevent the pencil core and the pencil core-shaped tool 10 in the storage cavity 212 from separating from the inside of the hollow core barrel 21.
[0054] Embodiment Three
[0055] This embodiment provides a mechanical pencil (not shown in the figure), which includes the mechanical pencil lead 20 as described in any of Embodiment 2. Specifically, the mechanical pencil in this embodiment also includes a barrel, a tip connected to one end of the barrel, and a pressing component disposed on the side wall or top of the barrel. The mechanical pencil lead 20 is disposed inside the barrel and cooperates with the pressing component. In this embodiment, when a lead is inserted into the mechanical pencil lead 20, the mechanical pencil can be used as a pen; when a lead-shaped tool 10 is inserted into the mechanical pencil lead 20, the mechanical pencil can be used as a manual tool, with the barrel serving as the grip of the manual tool; and the mechanical pencil lead 20 inside the mechanical pencil can store lead and / or the lead-shaped tool 10. A user carrying one mechanical pencil in this embodiment can achieve the functions of a pen and multiple manual tools.
[0056] Example 4
[0057] like Figures 5-11 As shown, this embodiment provides a dual-ended pen tool, which includes the mechanical pencil lead 20 described in any one of Embodiment 2. In this embodiment, one end of the dual-ended pen tool engages with the mechanical pencil lead 20, enabling it to function as both a mechanical pencil and a manual tool. The other end can be configured as a ballpoint pen or other tool, further increasing the variety of functions. Compared to the mechanical pencil in Embodiment 3, carrying a dual-ended pen tool from this embodiment can meet more usage needs.
[0058] Furthermore, such as Figures 5-11 As shown, the double-ended pen tool 30 also includes a hollow pen barrel 31 and pen tips 32 detachably connected to both ends of the hollow pen barrel 31. A pressing component 33 is provided in the middle of the hollow pen barrel 31, and a through hole 38 is provided on the side wall of the hollow pen barrel 31 to cooperate with the pressing component 33. At least one mechanical pencil lead 20 is installed between the pen tip 32 and the pressing component 33. Specifically, the pen tip 32 and the hollow pen barrel 31 are detachably connected by a snap-fit method; of course, in other embodiments, the pen tip 32 and the hollow pen barrel 31 can also be connected by other detachable connection methods, such as a threaded connection. In this embodiment, by detachably providing pen tips 32 at both ends of the hollow pen barrel 31, the user can easily replace the lead, mechanical pencil lead 20, or other tools on both sides of the double-ended pen according to actual usage needs. The pressing component 33 at least cooperates with the mechanical pencil lead 20 to provide pressing force to the mechanical pencil lead 20 to realize the mechanical pencil function or manual tool function.
[0059] Furthermore, such as Figures 5-11As shown, a second spring 36 and the mechanical pencil lead 20 are installed between one of the pencil tips 32 and the pressing assembly 33, while a third spring 37 and a tool at the other end are installed between the other pencil tip 32 and the pressing assembly 33. In this embodiment, the pressing assembly 33 not only provides pressing force to the mechanical pencil lead 20, but also cooperates with the second spring 36 and the third spring 37 to control the usage state of the mechanical pencil lead 20 and the tool at the other end; that is, the pressing assembly also serves a switching function. When the pressing component 33 moves, causing the second spring 36 to be compressed and the third spring 37 to be uncompressed, the mechanical pencil lead 20 protrudes to the outside of the corresponding tip 32, while the other end tool retracts to the inside of the corresponding tip 32 or is in a closed state; when the third spring 37 is compressed and the second spring 36 is uncompressed, the mechanical pencil lead 20 retracts to the inside of the corresponding tip 32, while the other end tool protrudes to the outside of the corresponding tip 32 or is in an activated state; when the second spring 36 is uncompressed and the third spring 37 is also uncompressed, the mechanical pencil lead 20 retracts to the inside of the corresponding tip 32, and the other end tool also retracts to the inside of the corresponding tip 32 or is in a closed state.
[0060] Furthermore, such as Figures 5-11 As shown, the other end of the tool is a press-type gel pen refill 341. Specifically, the end of the press-type gel pen refill 341 near the pen tip is fitted into the third spring 37, and the end of the press-type gel pen refill 341 away from the pen tip is inserted into the pressing assembly 33. When the gel pen function is needed, the press-type gel pen refill 341 is pressed by the pressing assembly 33, causing the press-type gel pen refill 341 to overcome the elastic force of the third spring 37 and protrude from the outside of the corresponding pen tip 32. In this embodiment, one end of the double-ended pen tool can realize the functions of a mechanical pencil and a manual tool, and the other end can realize the function of a gel pen.
[0061] Furthermore, such as Figures 5-11As shown, the pressing assembly 33 comprises a movable cylinder 331, and a pressing protrusion 332 arranged on the outer wall of the movable cylinder 331, the inside of the movable cylinder 331 is provided with a partition plate 333, the pressing protrusion 332 passes through the through hole 38 and extends to the outside of the intermediate hollow barrel 31, the hole wall of the through hole 38 is provided with a plurality of control steps matched with the pressing protrusion 332. In this embodiment, the automatic pencil inner core 20 and the other end tool (in this embodiment, the pressing ballpoint pen refill 341) are respectively inserted at both ends of the movable cylinder 331, when the pressing assembly 33 of the double-head pen tool is pressed at one end, the partition plate 333 exerts force on the automatic pencil inner core 20 or the other end tool (in this embodiment, the pressing ballpoint pen refill 341) of the corresponding end, so as to realize the switching of the two ends of the double-head pen tool; and by arranging a plurality of control steps matched with the pressing protrusion 332, the double-head pen tool is kept in the switched state.

The middle part of the middle hollow pen barrel 31 is provided with a pressing assembly 33, and the side wall of the middle hollow pen barrel 31 is provided with a through hole 38 matched with the pressing assembly 33. At least one of the pen heads 32 is installed between the pressing assembly 33 and the automatic pencil inner core 20. In the embodiment, the pen heads 32 are detachably arranged at both ends of the middle hollow pen barrel 31, so that the user can replace the inner core, the automatic pencil inner core 20 or other tools on both sides of the double-head pen according to the actual use requirements. The pressing assembly 33 is matched with at least the automatic pencil inner core 20 to provide pressing force for the automatic pencil inner core 20, so as to realize the functions of the automatic pencil or the manual tool.
[0067] Further, as shown in the embodiment four, Figures 11-12 One of the pen heads 32 is installed between the pressing assembly 33 and the second spring 36 and the automatic pencil inner core 20, and the other pen head 32 is installed between the pressing assembly 33 and the third spring 37 and the other end tool. In the embodiment, the pressing assembly 33 not only provides pressing force for the automatic pencil inner core 20, but also cooperates with the second spring 36 and the third spring 37 to control the use state of the automatic pencil inner core 20 and the other end tool, that is, the pressing assembly also plays a switching role. When the pressing assembly 33 moves to compress the second spring 36 and the third spring 37 is not compressed, the automatic pencil inner core 20 protrudes outside the corresponding pen head 32, and the other end tool is retracted inside the corresponding pen head 32 or in a closed state; when the third spring 37 is compressed and the second spring 36 is not compressed, the automatic pencil inner core 20 is retracted inside the corresponding pen head 32, and the other end tool protrudes outside the corresponding pen head 32 or is in an activated state; when the second spring 36 is not compressed and the third spring 37 is not compressed, the automatic pencil inner core 20 is retracted inside the corresponding pen head 32, and the other end tool is also retracted inside the corresponding pen head 32 or in a closed state.
[0068] Further, as shown in the embodiment four, Figures 11-12The other end tool part is a lamp assembly. The lamp assembly can be a lighting lamp assembly or a laser lamp assembly, and can also be other types of lamp assemblies. Specifically, the lamp assembly comprises, from outside to inside, a lamp bead 3444, a battery 3441, a conductive spring 3442, and a metal sheet 3445. The lamp bead 3444 is a lighting lamp bead or a laser lamp bead. The lamp bead 3444 is fixed at the end of the corresponding pen head 32 away from the middle hollow pen barrel 31. The light-emitting end of the lamp bead 3444 is arranged towards the outside of the double-head pen tool, and the wiring end of the lamp bead 3444 is arranged towards the inside of the middle hollow pen barrel 31 and is connected with a zero line 3443 and a third spring 37. The third spring 37 is actually a live wire. One end of the zero line 3443 away from the lamp bead 3444 extends to the inside of the middle hollow pen barrel 31 and is connected with the metal sheet 3445. One end of the third spring 37 away from the lamp bead 3444 is arranged in a suspended manner. The metal sheet 3445 is fixedly connected with the pressing assembly 33. One end of the conductive spring 3442 is fixedly and conductively connected with the metal sheet 3445. The battery 3441 is inserted into the inside of the pressing assembly 33 and one end thereof is in contact with the conductive spring 3442. The battery 3441 is tightly fitted with the pressing assembly 33. After the battery 3441 is inserted into the pressing assembly 33, a certain force is needed to pull it out, so as to prevent the battery 3441 from shaking during use and to prevent the battery 3441 from being separated from the conductive spring 3442. When the pressing assembly 33 drives the battery 3441 to move towards the lamp bead 3444, the end of the battery 3441 will be in contact with the suspended end of the third spring 37 and compress the third spring 37. The battery 3441 is conductive with the lamp bead 3444, the lamp bead 3444 is started, and the functions of the lighting lamp or the laser lamp are realized. When the pressing assembly 33 drives the battery 3441 to move away from the lamp bead 3444, the end of the battery 3441 will be separated from the suspended end of the third spring 37. The battery 3441 is not conductive with the lamp bead 3444, and the lamp bead 3444 is turned off. In this embodiment, one end of the double-head pen tool can realize the functions of the automatic pencil and the manual tool, and the other end can realize the function of the lamp.
[0069] Further, as Figures 11-12As shown, the pressing assembly 33 comprises a movable cylinder 331, and a pressing protrusion 332 arranged on the outer wall of the movable cylinder 331, the inside of the movable cylinder 331 is provided with a partition plate 333, the pressing protrusion 332 passes through the through hole 38 and extends to the outside of the intermediate hollow pen barrel 31, the hole wall of the through hole 38 is provided with a plurality of control steps matched with the pressing protrusion 332. In this embodiment, the automatic pencil inner core 20 and the other end tool part (in this embodiment, the lamp assembly) are respectively inserted at the two ends of the movable cylinder 331, when the pressing assembly 33 at one end of the double-head pen tool is pressed, the partition plate 333 exerts force on the automatic pencil inner core 20 or the other end tool part (in this embodiment, the lamp assembly) at the corresponding end, so as to realize the switching of the two ends of the double-head pen tool; and by arranging a plurality of control steps matched with the pressing protrusion 332, the double-head pen tool can be kept in the switched state. The pressing assembly 33 can reciprocate along the axial direction of the intermediate hollow pen barrel 31 and reciprocate rotate along the circumferential direction of the intermediate hollow pen barrel 31 under the action of external force.
[0070] Further, as Figures 11-12As shown, the control steps include a first control step 351, a second control step 352 and a third control step 353, in particular, the first control step 351, the second control step 352 and the third control step 353 are staggered in the axial direction of the middle hollow pen barrel 31 and in the circumferential direction of the middle hollow pen barrel 31. When the pressing protrusion 332 cooperates with the first control step 351, at this time the third spring 37 is compressed and the second spring 36 is not compressed, the automatic pencil inner core 20 is retracted into the inside of the corresponding pen head 32 and the third spring 37 and the battery 3441 in the other end tool (this embodiment is a lamp assembly) are in contact and powered on so that the lamp bead 3444 is in the starting state; when the pressing protrusion 332 cooperates with the second control step 352, at this time the second spring 36 is compressed and the third spring 37 is not compressed, the automatic pencil inner core 20 protrudes to the outside of the corresponding pen head 32 and the third spring 37 and the battery 3441 in the other end tool (this embodiment is a lamp assembly) are not in contact and powered off so that the lamp bead 3444 is in the off state, at this time, pressing the pressing assembly 33 downward along the vertical direction can apply force to the first spring 24 in the automatic pencil inner core 20, that is, realize the function of pressing the automatic pencil inner core 20; when the pressing protrusion 332 cooperates with the third control step 353, at this time the first spring 24 is compressed on the basis of the second spring 36 being compressed and the third spring 37 is not compressed, on the basis of the automatic pencil inner core 20 protruding to the outside of the corresponding pen head 32, the elastic clamping assembly is kept in the loose state, at this time, the pencil core-shaped tool 10 inserted into the automatic pencil inner core 20 can rotate 360° under the action of external force, as described in Embodiment One, at this time, when the user's hand holds the double-head pen tool and the pencil core-shaped tool 10 not clamped passes over the surface of the cut object (such as paper folding), the user can easily control the cutting direction of the blade part 121 by controlling the force direction of the hand, so as to form any required cutting curve on the surface of the cut object.
[0071] Further, as shown in Figures 11-12 When the pressing protrusion 332 is located between the first control step 351 and the second control step 352, at this time the second spring 36 is not compressed and the third spring 37 is also not compressed, the automatic pencil inner core 20 is retracted into the inside of the corresponding pen head 32 and the other end tool (this embodiment is a lamp assembly) is in the off state.
[0072] Embodiment Six
[0073] As shown in Figure 11 , 13As shown in Figure -14, this embodiment provides a dual-ended pen tool, which includes the mechanical pencil lead 20 described in any one of Embodiment 2. In this embodiment, one end of the dual-ended pen tool engages with the mechanical pencil lead 20, enabling it to function as both a mechanical pencil and a manual tool. The other end can be configured as a ballpoint pen or other tool, further increasing the variety of functions. Compared to the mechanical pencil in Embodiment 3, carrying a dual-ended pen tool from this embodiment can meet more usage needs.
[0074] Furthermore, such as Figure 11 , 13 As shown in Figure -14, the double-ended pen tool 30 includes a hollow pen barrel 31 and pen tips 32 detachably connected to both ends of the hollow pen barrel 31. A pressing component 33 is provided in the middle of the hollow pen barrel 31, and a through hole 38 is provided on the side wall of the hollow pen barrel 31 to cooperate with the pressing component 33. At least one mechanical pencil lead 20 is installed between the pen tip 32 and the pressing component 33. In this embodiment, by detachably providing pen tips 32 at both ends of the hollow pen barrel 31, the user can easily replace the lead, mechanical pencil lead 20, or other tools on both sides of the double-ended pen according to actual usage needs. The pressing component 33 cooperates with at least the mechanical pencil lead 20, providing pressing force to the mechanical pencil lead 20 to achieve the function of a mechanical pencil or a manual tool.
[0075] Furthermore, such as Figure 11 , 13 As shown in Figure -14, a second spring 36 and the mechanical pencil lead 20 are installed between one of the pencil tips 32 and the pressing assembly 33, while a third spring 37 and a tool at the other end are installed between the other pencil tip 32 and the pressing assembly 33. In this embodiment, the pressing assembly 33 not only provides pressing force to the mechanical pencil lead 20, but also cooperates with the second spring 36 and the third spring 37 to control the usage state of the mechanical pencil lead 20 and the tool at the other end; that is, the pressing assembly also serves a switching function. When the pressing component 33 moves and compresses the second spring 36 while the third spring 37 is not compressed, the mechanical pencil lead 20 protrudes to the outside of the corresponding tip 32, while the other end tool retracts to the inside of the corresponding tip 32 or is in a closed state; when the third spring 37 is compressed and the second spring 36 is not compressed, the mechanical pencil lead 20 retracts to the inside of the corresponding tip 32, while the other end tool protrudes to the outside of the corresponding tip 32 or is in an activated state; when the second spring 36 is not compressed and the third spring 37 is not compressed, the mechanical pencil lead 20 retracts to the inside of the corresponding tip 32, and the other end tool also retracts to the inside of the corresponding tip 32 or is in a closed state.
[0076] Furthermore, such asFigure 11 , 13 As shown in Figure -14, the other end tool is a screwdriver 342. When the screwdriver function is needed, the screwdriver 342 is pressed by the pressing component 33, causing the screwdriver 342 to overcome the elastic force of the third spring 37 and protrude from the outside of the corresponding pen tip 32. In this embodiment, one end of the double-ended pen tool can realize the functions of a mechanical pencil and a manual tool, and the other end can realize the function of a screwdriver.
[0077] Furthermore, such as Figure 11 , 13 As shown in Figure -14, the pressing assembly 33 includes a movable cylinder 331 and a pressing protrusion 332 disposed on the outer wall of the movable cylinder 331. A partition plate 333 is disposed inside the movable cylinder 331. The pressing protrusion 332 passes through the through hole 38 and extends to the outer side of the central hollow pen barrel 31. The wall of the through hole 38 is provided with multiple control steps that cooperate with the pressing protrusion 332. In this embodiment, the mechanical pencil lead 20 and the other end tool (in this embodiment, a screwdriver 342) are respectively inserted at both ends of the movable cylinder 331. When the pressing assembly 33 is pressed towards one end of the double-ended pen tool, the partition plate 333 applies force to the corresponding end of the mechanical pencil lead 20 or the other end tool (in this embodiment, a screwdriver 342) to achieve switching between the two ends of the double-ended pen tool. Furthermore, by providing multiple control steps that cooperate with the pressing protrusion 332, the double-ended pen tool is kept in the switched state. Under the action of external force, the pressing component 33 can reciprocate along the axial direction of the hollow pen barrel 31 and reciprocate along the circumferential direction of the hollow pen barrel 31.
[0078] Furthermore, such as Figure 11 , 13As shown in FIG. 14, the control steps include a first control step 351, a second control step 352, and a third control step 353, and in particular, the first control step 351, the second control step 352, and the third control step 353 are staggered in the axial direction of the intermediate hollow pen barrel 31 and in the circumferential direction of the intermediate hollow pen barrel 31. When the pressing block 332 cooperates with the first control step 351, the automatic pencil inner core 20 is retracted into the corresponding pen head 32 and the other end tool (screwdriver 342 in this embodiment) protrudes to a first position outside the corresponding pen head 32, and the third spring 37 is compressed and the second spring 36 is not compressed. Since the distance from the first position to the end of the corresponding pen head 32 is about 3mm (referring to the distance from the tip end of the pressing propelling pencil inner core 341 to the end of the corresponding pen head 32 when the pressing propelling pencil inner core 341 protrudes outside the corresponding pen head 32), the distance protruding to the first position is not enough for the screwdriver 342 to be used. Therefore, the control steps in this embodiment further include a fourth control step 354, when the pressing block 332 cooperates with the fourth control step 354, the automatic pencil inner core 20 is retracted into the corresponding pen head 32 and the other end tool protrudes to a second position outside the corresponding pen head 32, and the distance between the second position and the first control step 351 is greater than the distance between the first position and the first control step 351. This embodiment sets the fourth control step 354, when the pressing block 332 cooperates with the fourth control step 354, the third spring 37 is further compressed, so that the screwdriver 342 protrudes outward to the second position, so as to facilitate the use of the screwdriver 342.When the pressing protrusion 332 cooperates with the second control step 352, at this time the second spring 36 is compressed and the third spring 37 is not compressed, the mechanical pencil inner core 20 protrudes outside the corresponding pen head 32 and the other end tool (in this embodiment, the pressing ballpoint pen refill 341) retracts inside the corresponding pen head 32, at this time, the pressing assembly 33 is pressed downward along the vertical direction, the first spring 24 in the mechanical pencil inner core 20 is forced, that is, the function of pressing the mechanical pencil inner core 20 is realized; when the pressing protrusion 332 cooperates with the third control step 353, at this time the first spring 24 is compressed on the basis of the second spring 36 being compressed and the third spring 37 is not compressed, on the basis of the mechanical pencil inner core 20 protruding outside the corresponding pen head 32, the elastic clamping assembly is kept in a loosened state, at this time, the pencil core-shaped tool 10 inserted into the mechanical pencil inner core 20 can rotate 360° under the action of an external force, as described in Embodiment One, at this time, when the user's hand holds the double-head pen tool and the pencil core-shaped tool 10 not clamped passes over the surface of the cut object (such as paper), the user can easily control the cutting direction of the blade part 121 by controlling the force direction of the hand, so as to facilitate forming an arbitrary required cutting curve on the surface of the cut object.
[0079] Further, as shown in Figure 11 、 13 -14, when the pressing protrusion 332 is located between the first control step 351 and the second control step 352, at this time the second spring 36 is not compressed and the third spring 37 is also not compressed, the mechanical pencil inner core 20 and the other end tool (in this embodiment, the screwdriver 342) are retracted inside the corresponding pen head 32.
[0080] The above-described embodiments only express some implementation manners of the present application, the description is relatively specific and detailed, but it cannot be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, some modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
