[0034] Referring to Figures 1-2 and 10, the tool clamp of the present application comprises a clamp seat 1, a locking control 2 and a connecting rod member 3; the clamp seat 1 has a clamping channel 100 connecting the upper end and the lower end, and a coupling groove 10 penetrating the side wall of the clamp seat 1 and the clamping channel 100, and the side wall of the clamp seat 1 is configured with an elastically deformable portion 10' at a predetermined 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 clamp seat 1, so that the locking control 2 can be moved closer to or away from the outside of the clamp seat 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; moving the locking control closer to or away from the outside of the clamp seat 1 changes the position of the first side 101 of the coupling groove 10 relative to the second side 102, causing the elastically deformable portion 10' of the clamp seat 1 to elastically deform and change the size of the inner diameter of the clamping channel 100, thereby clamping or releasing the tool.

[0035] Specifically, when the locking control 2 is turned towards the clamp seat 1, the side of the clamp seat 1 near the coupling groove 10 is pulled, causing the elastically deformable portion 10' to elastically deform and reduce the inner diameter of the clamping channel 100, thereby clamping the tool n; when the locking control 2 is turned away from the clamp seat 1, the elastically deformable portion 10' is released, thereby restoring the normal state of the clamping channel 100 and releasing the clamping of the tool n, allowing the user to install or remove the tool n from above. The tool n can be a cutting knife (as shown in Figure 7), but it can also be a drawing pen or other tools used in conjunction.

[0036] Compared with the prior art, the tool clamp of the present application is configured with an elastically deformable portion 10' on the side wall of the clamp seat 1 at a predetermined distance from the coupling groove 10, and the size of the inner diameter of the clamping channel 100 is changed by manipulating the locking control 2 using the elastic deformation characteristics of the elastically deformable portion 10', thereby clamping or releasing the tool, reducing the number of parts of the tool clamp and simplifying the structure.

[0037] In order to realize the locking of the locking control 2, the connecting end of the locking control 2 and the hinge axis of the clamping seat 1 are ax1, the hinge axis of the connecting rod member 3 and the second side 102 are ax2, and the hinge axis of the connecting rod member 3 and the locking control 2 are ax3, wherein the hinge axis ax3 is closer to the free end of the locking control 2 relative to the hinge axis ax1. In this way, when the locking control 2 is close to the clamping seat 1, the self-locking effect can be realized to prevent the locking control 2 from being released by the tool.

[0038] As shown in FIG. 1 and FIG. 2, the elastic deformation part 10' is located on the side wall of the clamping seat 1 opposite to the coupling groove 10. The "elastic deformation part 10' is located on the side wall of the clamping seat 1 at a predetermined distance from the coupling groove 10" in the present application refers to 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 controlled by the locking control 2 to cause the elastic deformation of the elastic deformation part 10' under stress, 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 controlled by the locking control 2 to cause the elastic deformation of the elastic deformation part 10' under stress, so that the first side 101 of the coupling groove 10 moves relative to the second side 102.

[0039] 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 hinged in the first hinge groove 1011, such as being hinged 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 hinged in the second hinge groove 1021, such as being hinged by a pin shaft. The above structure makes the structure of the tool clamp compact and simple.

[0040] In some embodiments, the outer side of the clamping seat 1 adjacent to the locking control 2 is configured in an arc shape, and the part matched with the locking control 2 is also configured in an arc shape, so that the locking control 2 can be closer to the locking control 2 to ensure the clamping force on the tool, and at the same time, the dead angle position of the swinging of the locking control 2 is better utilized to realize self-locking. At the same time, it has the advantages of beauty and space saving.

[0041] In some embodiments, the clamping seat 1 is configured with a recess 103 near the surface of the locking control 2 in the clamping state, 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 with fingers.

[0042] In some embodiments, the inner side of the clamping seat 1 is configured 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 the part is larger by reducing the wall thickness in a simple structure.

[0043] As shown in FIGS. 1 and 2, in some embodiments, the cross section of the notch groove 100' is U-shaped, and the configuration of the shape can optimize the stress when the notch groove 100' is pressed, and will not cause local stress too large to break.

[0044] 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.

[0045] In some embodiments, the elastic deformation part 10' is configured 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.

[0046] Referring to FIGS. 1, 2 and 10, 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 material.

[0047] Of course, in other embodiments, the clamping seat 1 and the tool support member 4 are manufactured separately, and then connected together by connecting members such as screws, or connecting processes such as welding.

[0048] Referring to FIGS. 3 and 6, in some embodiments, the inner side of the clamping seat 1 is configured with an increased adhesion clamping part, which at least contacts a part of the tool n. The clamping part is specifically 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 connecting members such as screws, adhesives, inlaying, etc. The clamping part plays a role of clamping the tool n, and prevents the tool from moving upward during operation.

[0049] In other embodiments, the inner side of the clamping seat 1 is provided with a plurality of vertical inlay grooves 105, and flexible clamping strips (not shown in the figure) are assembled in the inlay grooves 105, and the flexible clamping strips protrude from the inner side surface of the clamping seat 1.

[0050] The inlay groove 105 is configured with a radial limiting structure, such as the dovetail groove structure shown in FIG. 6, or a T-shaped groove structure.

[0051] Of course, in order to facilitate assembly, the inlay groove at least communicates with at least one end of the clamping seat 1.

[0052] In the preferred embodiment, the upper end of the embedding groove 105 is not open, because the force of the tool relative to the clamping portion is upward during use, so that the upward movement of the flexible clamping strip is limited.

[0053] In the scheme shown in FIGS. 3-6, the flexible clamping layer 104 is arranged in the clamping seat 1, and the inside of the flexible clamping layer 104 constitutes the clamping channel 100. The flexible clamping layer 104 can be made of silica gel, rubber, resin material, etc. that can increase the clamping friction. The flexible clamping layer 104 plays a better role in clamping the tool n and prevents the tool from moving upward during operation.

[0054] 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. The limiting protrusions have the effect of increasing the clamping friction.

[0055] 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.

[0056] The clamping seat 1 can be configured with an embedding groove 105 for positioning the flexible clamping layer 104, which can prevent the flexible clamping layer 104 from rotating. In some embodiments, the embedding groove 105 is configured with a radial limiting structure, such as the dovetail groove structure shown in FIG. 6, or a T-shaped groove structure. The flexible clamping layer 104 is filled to form a limiting rib structure 1042 at the embedding groove 105 during injection molding.

[0057] As shown in FIG. 6, in some embodiments, the flexible clamping layer 104 is filled to form a gap filling portion 1041 at the gap groove 100' during injection molding, which plays a role in shielding the gap groove 100', while not affecting the elastic deformation of the elastic deformation portion 10'.

[0058] Referring to FIGS. 3-5, a limiting step 104' is provided on the upper 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 gap groove 100' penetrates the limiting step 104', and the gap filling portion 1041 extends along the gap groove 100' to above the limiting step 104'.

[0059] 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.

[0060] Referring to FIG. 7 to FIG. 9, another embodiment of the tool clamp provided by the present application includes a clamp seat 1, a locking control 2 and a connecting rod member 3; the clamp seat 1 has a clamping channel 100 which is connected with the upper end and the lower end, and a coupling part 10a which extends vertically to the upper side and the lower side of the side wall of the clamp seat 1, and the side wall of the clamp seat 1 which is located at a preset distance from the coupling part 10a is configured with an elastic deformation part 10'; the connecting end of the locking control 2 is hinged to the first side 101 of the coupling part 10a of the clamp seat 1, so that the locking control 2 can be close to or away from the outside of the clamp seat 1; the connecting rod member 3 is hinged to the second side 102 of the coupling part 10a and the connecting end of the locking control 2 respectively; the locking control is controlled to be close to or away from the clamp seat 1, so that the elastic deformation part 10' of the clamp seat 1 is elastically deformed to change the inner diameter of the clamping channel 100, thereby achieving tool clamping or releasing, and the coupling part 10a accepts the position change of the first side 101 when the inner diameter of the clamping channel 100 changes.

[0061] Specifically, when the locking control 2 is turned to the direction close to the clamp seat 1, the side of the clamp seat 1 close to the coupling part 10a is pulled to make the elastic deformation part 10' elastically deformed to reduce the inner diameter of the clamping channel 100, thereby achieving clamping of the tool n; when the locking control 2 is turned to the direction away from the clamp seat 1, the elastic deformation part 10' is released, thereby restoring the normal state of the clamping channel 100 and releasing the clamping of the tool n, and the user can install or remove the tool n from above. The tool n can be a cutter as shown in FIG. 7, and of course can also be a drawing pen and other tools used in conjunction.

[0062] In this embodiment, the position of the elastic deformation part 10' relative to the coupling part 10a is set in accordance with the requirements of the setting of the elastic deformation part 10' relative to the coupling groove 10 in the present application, and specific reference can be made to the related content of the elastic deformation part 10' relative to the coupling groove 10.

[0063] In this embodiment, the connection mode of the locking control 2 with the connecting rod member 3 and the clamp seat 1 is the same as or similar to the connection mode in other embodiments of the present application.

[0064] The tool clamp of the present embodiment changes the size of the inner diameter of the clamping channel 100 by controlling the locking control 2 to utilize the elastic deformation characteristics of the elastic deformation part 10', thereby achieving tool clamping or releasing, reducing the parts of the tool clamp and simplifying the structure.

[0065] In this embodiment, the elastic deformation part 10' can also be formed by reducing the thickness of the side wall of the clamp seat 1, so that the elastic deformation of this part is greater than that of the adjacent part.

[0066] Of course, in an embodiment, the inner side of the clamping seat 1 is configured with a vertical notch groove 100', the wall of the notch groove 100 is configured as at least part of the elastic deformation part 10', and the cross section of the notch groove 100 is preferably U-shaped.

[0067] On the other hand, the clamping seat 1 is configured with a flexible clamping layer 104, and the inside of the flexible clamping layer 104 constitutes the clamping channel 100. The material of the flexible clamping layer 104 can be selected as known from other embodiments, such as silicone, rubber, resin material, etc., which can increase the clamping friction.

[0068] Specifically, 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. The specific manufacturing method is the same as or similar to other embodiments of the present application.

The filling part 1043 is a flexible material and does not affect the position change of the first side 101.

[0070] 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.

It can be understood that the flexible material of the present scheme can be fixed in the coupling groove 10 by injection molding, bonding or the like.

[0072] Another scheme (not shown) of the coupling part 10a is that the coupling part 10a is formed by a flexible structure with reduced thickness of the side wall of the clamping seat 1. As in other embodiments of the present application, the coupling part 10a is configured in the same way as the elastic deformation part 10', and of course the thinner the coupling part 10a is, the better.
