[0039] Embodiment one

[0040] Referring to Figures 1 to 5, the cutting component a of the present application comprises a support 5, a support member 4, a tool holding mechanism b, a motor m and a driving connection member m', the support member 4 is movably connected to the support 5, the tool holding mechanism b is configured on the support member 4 for installing a working tool, the motor m is installed on the support 5 in an attitude with the output shaft m1 upward for driving the support member 4, the driving connection member m' comprises a lead screw m2 fixed longitudinally on the support member 4 at a side close to the tool holding mechanism b, a driving nut m3 configured on the support 5 for threadedly connecting with the lead screw m2, and at least one gear pair, the driving nut m3 is drivingly connected with the output shaft m1 of the motor m through the at least one gear pair, the driving nut m3 can be driven to rotate by the at least one gear pair when the output shaft m1 of the motor m is rotatable, so that the driving nut m3 drives the lead screw m2 to ascend and descend, and the lead screw m2 drives the support member 4 and the tool holding mechanism b to move along a working direction.

[0041] The working tool can be a cutting knife, and of course can also be a drawing pen or other tools used in conjunction.

[0042] As shown in Figures 3 to 5, in a specific embodiment, the output shaft m1 of the motor m is fixedly connected with an output gear m41, the periphery of the driving nut m3 is configured with a driving tooth m42, and the support 5 is configured with a double gear m43 between the driving nut m3 and the output gear m41, the double gear m43 comprises a first driven gear m431 engaged with the output gear m41 and a second driven gear m432 engaged with the driving tooth m42.

[0043] The motor m is a stepping motor, a servo motor or other known motor, and the driving control of the motor m is not the improvement of the present application, and those skilled in the art can realize it by the control means of the prior art.

[0044] The present application adopts a screw nut mechanism to drive the working tool, which is simple, stable and reliable, fast in response speed, and good in economy. The screw rod m2 is arranged on the side of the supporting member 4 close to the tool holding mechanism b, and the lifting of the screw rod m2 is realized through at least one gear pair, so as to shorten the distance between the supporting member 4 and the tool holding mechanism b from the screw rod m2, and ensure that the working tool on the tool holding mechanism b can effectively apply force to the working object. Compared with the prior art, the output shaft m1 of the motor m and the screw rod m2 are arranged longitudinally, and the driving force is transmitted through at least one gear pair from the horizontal direction. When the screw rod m2 is driven to lift, the motor m will not directly shake up and down due to the longitudinal reaction force, which ensures the transmission efficiency of the driving force, accurately controls the lifting of the screw rod m2, and improves the response efficiency. In addition, the screw rod m2 is arranged along the longitudinal direction of the supporting member 4, so that the side of the supporting member 4 close to the support 5 is parallel to the screw rod m2 and the output shaft of the motor m, and the side of the supporting member 4 close to the support 5 has high perpendicularity. When the screw rod m2 acts, the driving supporting member 4 moves stably up and down along a vertical axis as a whole, which ensures the stability of the cutting part.

[0045] Referring to FIGS. 5 and 6, the supporting member 4 includes a vertically extending supporting member body 41 and a driving base 42 configured on the rear side of the upper portion of the supporting member body 41.

[0046] The driving base 42 is integrally formed with the upper portion of the supporting member body 41 transversely, which ensures the stability of the structure and simplifies the production process. For example, it can be integrally formed by injection molding. In an embodiment, the surface of the driving base 42 is planar.

[0047] Referring to FIGS. 3 and 5, the support 5 includes a support body 51 configured with a motor mounting area and a cover 52 mounted on the upper side of the support body 51 for fixing the motor m. The cover 52 is configured with an upper guide protrusion 53 extending below the driving base 42 towards the supporting member body 41. The upper guide protrusion 53 is configured with an assembly hole 54 penetrating through the upper and lower sides thereof. A bearing 55 is arranged in the assembly hole 54. The driving nut m3 is rotatably assembled on the bearing 55.

[0048] Referring to Fig. 5, the driving nut m3 comprises a rotating shaft part m31 rotatably matched with the bearing 55, and a transmission part m32 connected to the upper end of the rotating shaft part m31, the driving teeth m42 are configured on the periphery of the transmission part m32, the rotating shaft part m31 is detachably clamped with a clamping spring m34 abutting against the bottom of the bearing 55, and the lead screw m2 penetrates through the transmission part m32 and the rotating shaft part m31. The rotating shaft part m31, the driving teeth m42 and the transmission part m32 are preferably integrally connected, such as integrally formed, welded, etc. At least one of the transmission part m32 and the rotating shaft part m31 is threadedly connected with the corresponding other, and the corresponding other of the transmission part m32 and the rotating shaft part m31 is provided with an internal thread threadedly connected with the lead screw m2.

[0049] As shown in Figs. 1 to 6, the support member 4 is movably connected with the support base 5 through a guide rod 56. In a specific embodiment, the upper guide protrusion 53 is provided with the guide rod 56 extending along the moving direction of the support member 4 at opposite sides of the assembly hole 54, the driving base 42 is configured with a movable hole 44 through which the guide rod 56 passes, and the rear side of the support member body 41 is configured with a sleeve 45 slidably connected with the guide rod 56. The provision of the guide rod 56 can improve the smoothness and smoothness of the movement of the support member 4, and enhance the installation stability of the support member 4.

[0050] As shown in Fig. 3, in order to further improve the reliability of the guide rod 56, the support base body 51 is configured with a lower guide protrusion 57 extending towards the support member body 41, and the lower end of the guide rod 56 is fixedly connected with the lower guide protrusion 57.

[0051] In an embodiment, the width of the support member body 41 is at least two-thirds of the width of the support base 5. The width of the support member body 41 is designed to block the connecting structure of the support member 4 and the support base 5 to make the front side surface of the cutting member neat and beautiful.

[0052] In an embodiment, the support member 4 is injection molded. The support member 4 with this structure is easy to produce and manufacture.

[0053] The support base body 51 is provided with a position detection element detecting the position of the support member 4 on the front side, and a trigger part corresponding to the trigger detection element is provided on the rear side of the support member body 41. The position detection element is a prior art.

[0054] The tool holding mechanism b of the present application is described below:

[0055] Referring to FIG. 7 to FIG. 15, the tool holding mechanism b comprises a holder 1, a locking control 2 and a connecting rod member 3; the holder 1 has a clamping channel 100 connecting the upper end and the lower end, and a coupling groove 10 penetrating through the side wall of the holder 1 and the clamping channel 100, and the side wall of the holder 1 is configured with an elastically deformable portion 10' at a preset distance from the first side 101 of the coupling groove 10; the connecting end of the locking control 2 is hinged to the first side 101 of the coupling groove 10 of the holder 1, so that the locking control 2 can be close to or away from the outside of the holder 1; the connecting rod member 3 is hinged near the connecting end of the locking control 2 and the second side 102 of the coupling groove 10, respectively; controlling the locking control to be close to or away from the outside of the holder 1 changes the position of the first side 101 of the coupling groove 10 relative to the second side 102, so that the elastically deformable portion 10' of the holder 1 is elastically deformed to change the size of the inner diameter of the clamping channel 100, achieving clamping or releasing the tool.

[0056] Specifically, when the locking control 2 is turned towards the holder 1, the side of the holder 1 close to the coupling groove 10 is pulled to cause the elastically deformable portion 10' to elastically deform and reduce the inner diameter of the clamping channel 100, achieving clamping the tool, when the locking control 2 is turned away from the holder 1, the elastically deformable portion 10' is released, so that the clamping channel 100 returns to normal, releasing the clamping of the tool, and the user can install or remove the tool from above.

[0057] The tool holding mechanism b is configured with the elastically deformable portion 10' on the side wall of the holder 1 at a preset distance from the coupling groove 10, and the size of the inner diameter of the clamping channel 100 is changed by the elastic deformation of the elastically deformable portion 10' through the locking control 2, achieving clamping or releasing the tool, reducing the parts of the tool holding mechanism b and simplifying the structure.

[0058] In order to achieve the locking of the locking control 2, the hinging axis of the connecting end of the locking control 2 and the holder 1 is ax1, the hinging axis of the connecting rod member 3 and the second side 102 is ax2, and the hinging axis of the connecting rod member 3 and the locking control 2 is ax3, wherein the hinging axis ax3 is closer to the free end of the locking control 2 than the hinging axis ax1. In this way, when the locking control 2 is close to the holder 1, the self-locking effect can be achieved to prevent the locking control 2 from releasing the tool.

[0059] As shown in FIG. 7 and FIG. 8, the elastic deformation part 10' is located on the side wall of the clamping seat 1 opposite to the coupling groove 10. In the present application, the "elastic deformation part 10' is located on the side wall of the clamping seat 1 opposite to the coupling groove 10 at a predetermined distance" means that the distance between the elastic deformation part 10' and the coupling groove 10 can ensure that the part of the clamping seat 1 located on the first side 101 of the coupling groove 10 can be forced to make the elastic deformation part 10' elastically deform by the locking control 2, so that the first side 101 of the coupling groove 10 moves relative to the second side 102, and the size of the inner diameter of the clamping channel 100 is changed. It can be easily understood that the greater the distance between the elastic deformation part 10' and the first side 101 of the coupling groove 10, the easier the elastic deformation of the elastic deformation part 10'. However, since the clamping seat 1 is connected to the tool support member 4 of the cutting component a, the maximum position is adjacent to the tool support member 4. The preferred position is that the elastic deformation part 10' is arranged at the opposite position of the coupling groove 10 and adjacent to the opposite position. Of course, as mentioned above, the position of the elastic deformation part 10' provided in the present application is not limited to the above-mentioned preferred position, as long as it can ensure that the part of the clamping seat 1 located on the first side 101 of the coupling groove 10 can be forced to make the elastic deformation part 10' elastically deform by the locking control 2, so that the first side 101 of the coupling groove 10 moves relative to the second side 102.

[0060] In some embodiments, the connecting end of the locking control 2 is provided with a first hinge groove 1011, and the connecting rod member 3 is hingedly connected to the first hinge groove 1011, such as being hingedly connected by a pin shaft. The second side 102 is provided with a second hinge groove 1021, and the other end of the connecting rod member 3 is hingedly connected to the second hinge groove 1021, such as being hingedly connected by a pin shaft. The above structure makes the tool holding mechanism b compact and simple.

[0061] In some embodiments, the outer side of the clamping seat 1 adjacent to the locking control 2 is arc-shaped, and the part matched with the locking control 2 is also arc-shaped, so that the locking control 2 can be closer to the locking control 2 to ensure the clamping force on the tool, and better utilize the swing dead angle position of the locking control 2 to achieve self-locking. At the same time, it has the advantages of beauty and space saving.

[0062] In some embodiments, the surface of the clamping seat 1 adjacent to the freedom of the locking control 2 (in the clamping state) is provided with a recess 103, and the free end of the locking control 2 is not close to the clamping seat 1, so as to facilitate the user to operate the locking control 2 by fingers.

[0063] In some embodiments, the inner side of the clamping seat 1 is provided with a vertical notch groove 100', and the wall of the notch groove 100 is configured as at least part of the elastic deformation part 10', so that the elastic deformation of this part is larger by reducing the wall thickness in a simple structure.

[0064] As shown in Figs. 7 and 8, in some embodiments, the notch groove 100' is in a U-shaped cross section, and the U-shaped structure can optimize the stress distribution when the notch groove 100' is pressed, and can prevent the notch groove 100' from being broken due to excessive stress.

[0065] Of course, in some embodiments, the inner side of the elastic deformation part 10' is not provided with the notch groove 100', as long as the material of the manufactured elastic deformation part 10' meets the elastic requirements.

[0066] In some embodiments, the elastic deformation part 10' is formed by reducing the thickness of the side wall of the clamping seat 1, that is, the thickness of the side wall of the part is smaller than that of the adjacent part, so that the elastic deformation of the part is larger than that of the adjacent part.

[0067] Referring to Figs. 7, 8 and 9, in some embodiments, the clamping seat 1 is integrated with the tool support member 4 of the cutting component a. For example, the clamping seat 1 and the tool support member 4 are integrally formed by using plastic or metal materials.

[0068] Of course, in other embodiments, the clamping seat 1 and the tool support member 4 are manufactured separately, and then connected together by using connecting members such as screws, or connecting processes such as welding.

[0069] In some embodiments, the inner side of the clamping seat 1 is provided with a clamping part for increasing adhesion, and the clamping part at least contacts a part of the tool. The clamping part can be, for example, one or more flexible strips, protrusions, etc., which are made of, for example, silica gel or rubber, and are fixed to the inner side of the clamping seat 1 by using connecting members such as screws, adhesives, inlaying, etc. The clamping part can clamp the tool, and prevent the tool from moving upward during operation.

[0070] In other embodiments, the inner side of the clamping seat 1 is provided with a plurality of vertical inlay grooves, and flexible clamping strips (not shown in the figures) are arranged in the inlay grooves, and the flexible clamping strips protrude from the inner side surface of the clamping seat 1.

[0071] The inlay groove is provided with a radial limiting structure, for example, a dovetail groove structure as shown in Fig. 4, or a T-shaped groove structure.

[0072] Of course, in order to facilitate assembly, the inlay groove is at least connected to at least one end of the clamping seat 1.

[0073] In a preferred embodiment, the upper end of the inlay groove is not open, because the force of the tool relative to the clamping part is upward during use, and thus the upward movement of the flexible clamping strip can be limited.

[0074] In the scheme shown in Figs. 9 to 11, the clamping seat 1 is provided with a flexible clamping layer 104, and the inside of the flexible clamping layer 104 constitutes the clamping channel 100. The flexible clamping layer 104 can be made of materials such as silica gel, rubber, resin materials, etc., which can increase the clamping friction. The flexible clamping layer 104 can clamp the tool better, and prevent the tool from moving upward during operation.

[0075] In some embodiments, the inner side of the flexible clamping layer 104 is configured with a plurality of limiting protrusions (not shown), which can be a plurality of limiting protrusions, protrusions or special-shaped protrusions arranged at intervals, etc., and the limiting protrusions have the effect of increasing clamping friction.

[0076] In some embodiments, the clamping seat 1 is made of plastic material, and the flexible clamping layer 104 is formed in the clamping seat 1 by secondary injection molding. Of course, it can also be made in parts and assembled.

[0077] The clamping seat 1 can be configured with a fitting groove 105 for positioning the flexible clamping layer 104, which can prevent the flexible clamping layer 104 from rotating. In some embodiments, the fitting groove 105 is configured with a radial limiting structure, such as the dovetail groove structure shown in FIG. 13, or a T-shaped groove structure. The flexible clamping layer 104 is filled to form a limiting rib structure 1042 at the fitting groove 105 during injection molding.

[0078] As shown in FIGS. 10-12, in some embodiments, the flexible clamping layer 104 is filled to form a notch filling portion 1041 at the notch groove 100' during injection molding, which plays a role of shielding the notch groove 100' while not affecting the elastic deformation of the elastic deformation portion 10'.

[0079] Referring to FIGS. 9-11, a limiting step 104' is provided on the upper side of the inner side of the clamping seat 1, and the flexible clamping layer 104 is injection molded on the lower side of the limiting step 104'. Of course, the notch groove 100' penetrates the limiting step 104', and the notch filling portion 1041 extends along the notch groove 100' to above the limiting step 104'.

[0080] In other embodiments, one or more flexible clamping portions (not shown in the drawings) can be arranged on the side wall of the clamping channel 100.

[0081] Referring to FIGS. 13-15, another embodiment of the tool holding mechanism b provided by the present application includes a clamping seat 1, a locking control 2 and a connecting rod member 3; the clamping seat 1 has a clamping channel 100 communicating with the upper end and the lower end, and a coupling portion 10a vertically extending to the upper side and the lower side of the side wall of the clamping seat 1, and the clamping seat 1 is configured with an elastic deformation portion 10' on the side wall at a predetermined distance from the coupling portion 10a; the connecting end of the locking control 2 is hinged to the first side 101' of the coupling portion 10a of the clamping seat 1, so that the locking control 2 can be close to or away from the outside of the clamping seat 1; the connecting rod member 3 is hinged to the second side 102 of the coupling portion 10a and the connecting end of the locking control 2, respectively; controlling the locking control to be close to or away from the clamping seat 1 causes the elastic deformation portion 10' of the clamping seat 1 to elastically deform to change the inner diameter of the clamping channel 100, thereby achieving tool clamping or releasing, and the coupling portion 10a accepts the position change of the first side 101' when the inner diameter of the clamping channel 100 changes.

[0082] Specifically, when the locking control 2 is turned towards the clamping seat 1, the clamping seat 1 is pulled towards the coupling portion 10a side to cause the elastic deformation portion 10' to elastically deform to reduce the inner diameter of the clamping channel 100, thereby achieving clamping of the tool. When the locking control 2 is turned away from the clamping seat 1, the elastic deformation portion 10' is released, thereby restoring the normal state of the clamping channel 100 and releasing the clamping of the tool. The user can install or remove the tool from above. In the embodiment, the position of the elastic deformation portion 10' relative to the coupling portion 10a is set in accordance with the requirements of the elastic deformation portion 10' relative to the coupling groove 10 in the present application. For details, please refer to the relevant content of the elastic deformation portion 10' relative to the coupling groove 10.

[0083] The connection mode of the locking control 2 with the connecting rod member 3 and the clamping seat 1 is the same as or similar to that in other embodiments of the present application.

The filling portion 1043 is made of flexible material and does not affect the position change of the first side edge 101'.

[0090] In other embodiments, the flexible clamping layer 104 covers the inner side of the coupling groove 10 without extending into the interior of the coupling groove 10.

[0091] Referring to FIGS. 13-15, in another embodiment, the coupling portion 10a is formed by a vertical coupling groove 10 provided in the clamping seat 1 and a flexible material (not shown) filling the coupling groove 10, wherein the flexible material and the coupling groove 10 constitute the coupling portion 10a. It can be understood that the flexible material in this embodiment can be fixed in the coupling groove 10 by injection molding, adhesion or the like.

[0092] In another embodiment (not shown), the coupling portion 10a is formed by an elastically deformable structure with reduced thickness of the side wall of the clamping seat 1. As in other embodiments of the present application, the elastically deformable portion 10' is formed in the same manner, and of course the thickness of the coupling portion 10a is as thin as possible.
