This problem is solved by constructing an elastic deformation part in the clamp and utilizing the elastic deformation characteristics of the elastic deformation part by manipulating the locking control to change the size of the inner diameter of the clamping channel.

[0034] See also Figure 1 to Figure 2 as well as Fig.10 The tool clamp of 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 connecting the upper end and the lower end, and a coupling groove 10 penetrating the side wall of the clamping seat 1 and the clamping channel 100, and the side wall of the clamping seat 1 located at a preset distance relative to the first side 101 of the coupling groove 10 is constructed with an elastic deformation portion 10'; the connecting end of the locking control 2 is hinged to the first side 101 of the coupling groove 10 of the clamping seat 1, so that the locking control 2 can move closer to or farther away from the outer side of the clamping seat 1; the connecting rod member 3 is respectively hinged to the second side 102 of the coupling groove 10 and the vicinity of the connecting end of the locking control 2; manipulating the locking control to move closer to or farther away from the outer side of the clamping seat 1 changes the position of the first side 101 of the coupling groove 10 relative to the second side 102, so that the elastic deformation portion 10' of the clamping seat 1 is elastically deformed to 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 toward the clamp seat 1, the side of the clamp seat 1 close to the coupling groove 10 is pulled so that the elastic deformation part 10' is elastically deformed to 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 elastic deformation part 10' is released, thereby restoring the normal state of the clamping channel 100 and releasing the clamping of the tool n. The user can install or remove the tool n from above. The tool n can be a cutter (such as Figure 7 As shown), of course, it can also be other supporting tools such as drawing pens.

[0036] Compared with the prior art, the tool clamp of the present application constructs an elastic deformation portion 10' on the side wall of the clamping base 1 at a preset distance relative to the coupling groove 10, and utilizes the elastic deformation characteristics of the elastic deformation portion 10' by manipulating the locking control 2 to change the size of the inner diameter of the clamping channel 100, thereby achieving tool clamping or release, reducing the parts of the tool clamp and simplifying the structure.

[0037] In order to achieve the locking of the locking control 2, the hinge axis between the connection end of the locking control 2 and the clamp seat 1 is ax1, the hinge axis between the connecting rod member 3 and the second side 102 is ax2, and the hinge axis between the connecting rod member 3 and the locking control 2 is ax3, wherein the hinge axis ax3 is closer to the free end of the locking control 2 than the hinge axis ax1. In this way, when the locking control 2 is close to the clamp seat 1, a self-locking effect can be achieved to prevent the locking control 2 from moving and releasing the tool.

[0038] like Figure 1 and Figure 2 As shown, the elastic deformation part 10' is located on the side wall of the clamp seat 1 opposite to the coupling groove 10. In the present application, "the side wall of the clamp seat 1 located at a preset distance relative to the coupling groove 10 is structured with an elastic deformation part 10'" means that the distance between the elastic deformation part 10' and the coupling groove 10 can ensure that the locking control 2 can control the force of the part of the clamp seat 1 located on the first side (101) of the coupling groove 10 to cause the elastic deformation part 10' to elastically deform, 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 of the elastic deformation part 10' relative to the first side 101 of the coupling groove 10, the easier the elastic deformation part 10' is to elastically deform, but because the clamp seat 1 is connected to the tool support member 4 of the cutting component a, the maximum position is the position adjacent to the tool support member 4. The preferred position is that the elastic deformation portion 10' is configured at the position directly opposite to the coupling groove 10 and adjacent to the directly opposite position. Of course, as mentioned above, the position where the elastic deformation portion 10' protected by the present application is set is not limited to the above-mentioned preferred position, as long as it satisfies "it can be ensured that the locking control 2 can control the force applied to the part of the clamp seat 1 located on the first side (101) of the coupling groove 10 to cause the elastic deformation portion 10' to undergo elastic deformation, so that the first side 101 of the coupling groove 10 moves relative to the second side 102".

[0039] In some embodiments, the connection 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 by a pin. 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 by a pin. With the above structure, the structure of the tool clamp is compact and simple.

[0040] In some embodiments, the outer side of the clamp seat 1 adjacent to the locking control 2 is configured to be arc-shaped, and the part of the locking control 2 that cooperates with it 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 at the same time, the swing dead angle position of the locking control 2 is better utilized to achieve self-locking. At the same time, it is both aesthetically pleasing and reduces space occupation.

[0041] In some embodiments, a recess 103 is constructed on the surface of the clamp base 1 close to the freedom of the locking control 2 (in the clamped state), and the free end of the locking control 2 is not close to the clamp base 1 to facilitate the user's finger manipulation of the locking control 2.

[0042] In some embodiments, a vertical notch 100' is formed on the inner side of the clamp 1, and the wall of the notch 100 forms at least a part of the elastic deformation portion 10', and the elastic deformation of this portion is increased by reducing the wall thickness with a simple structure.

[0043] As attached Figure 1 and Figure 2 As shown, in some embodiments, the cross section of the notch groove 100 ′ is U-shaped. This shape structure can optimize the force of the notch groove 100 ′ when it is squeezed, and will not cause excessive local force and breakage.

[0044] Of course, in some embodiments, the inner side of the elastic deformation portion 10 ′ is not provided with the notch groove 100 ′, as long as the material of the elastic deformation portion 10 ′ meets the elasticity requirement.

[0045] In some embodiments, the elastic deformation portion 10 ′ is formed by a reduced thickness structure of the side wall of the clamping seat 1 , that is, the thickness of the side wall of this portion is smaller than that of the adjacent portion, so that the elastic deformation of this portion is greater than that of the adjacent portion.

[0046] See also Figure 1 , Figure 2 and Fig.10 In some embodiments, the clamping seat 1 and the tool support member 4 of the cutting component a are integrated, such as integrally formed of plastic or metal materials.

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

[0048] See also Figure 3 and Figure 6In some embodiments, a clamping part for increasing adhesion is disposed inside the clamping seat 1, and the clamping part at least contacts a part of the tool n; the clamping part is specifically one or more flexible bars, protrusions, etc., such as made of silicone or rubber, and fixed to the inside of the clamping seat 1 by means of connecting parts such as screws, adhesives, inlays, etc. The clamping part plays the role of clamping the tool n to prevent the tool from moving upward during operation.

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

[0050] The engaging groove 105 is configured with a radial limiting structure, such as Figure 6 The dovetail groove structure or T-slot structure is shown.

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

[0052] In a preferred embodiment, the upper end of the engaging groove 105 is closed, because during use, the force of the tool relative to the clamping portion is upward, which can limit the upward movement of the flexible clamping strip.

[0053] exist Figures 3 to 6 In the illustrated solution, a flexible interlayer 104 is disposed in the clamping seat 1, and the interior of the flexible interlayer 104 constitutes the clamping channel 100. The flexible interlayer 104 can be made of materials such as silicone, rubber, and resin materials that can increase the clamping friction. The flexible interlayer 104 plays a role in better clamping the tool n and preventing the tool from moving upward during operation.

[0054] In some embodiments, the inner side of the flexible interlayer 104 is constructed with a plurality of limiting protrusions (not shown), which may be a plurality of spaced limiting protrusions, protrusions or special-shaped protrusions, etc. The limiting protrusions serve to increase the clamping friction.

[0055] In some embodiments, the clamping base 1 is made of plastic material, and the flexible interlayer 104 is formed in the clamping base 1 by secondary injection molding. Of course, it can also be made in parts and then assembled.

[0056] The clamping seat 1 may be provided with an engaging groove 105 for positioning the flexible interlayer 104, so as to prevent the flexible interlayer 104 from rotating. In some embodiments, the engaging groove 105 is provided with a radial limiting structure, such as Figure 6 The dovetail groove structure or T-shaped groove structure shown is shown. When the flexible interlayer 104 is injection molded, the embedded groove 105 is filled with a limiting rib structure 1042 .

[0057] like Figure 6As shown, in some embodiments, the flexible interlayer 104 is filled with a gap filling portion 1041 at the gap groove 100 ′ during injection molding, and the gap filling portion 1041 serves to shield the gap groove 100 ′ while not affecting the elastic deformation of the elastic deformation portion 10 ′.

[0058] See also Figures 3 to 5 A limiting step 104' is provided on the upper inner side of the clamp seat 1, and the flexible interlayer 104 is injection molded on the lower side of the limiting step 104'. Of course, the notch groove 100' passes through the limiting step 104', and the notch filling portion 1041 extends along the notch groove 100' to above the limiting step 104'.

[0059] In other embodiments, one or more flexible clamping portions (not shown in the drawings) may be disposed on the side wall of the clamping channel 100 .

[0060] See also Figures 7 to 9 , another embodiment of a tool clamp 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 connecting the upper end and the lower end, and a coupling portion 10a extending vertically to the upper and lower sides of the side wall of the clamping seat 1, and the side wall of the clamping seat 1 located at a preset distance relative to the coupling portion 10a is constructed with an elastic deformation portion 10'; 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 move closer to or farther away from the outer side of the clamping seat 1; the connecting rod member 3 is respectively hinged to the second side 102 of the coupling portion 10a and the vicinity of the connecting end of the locking control 2; the locking control is manipulated to move closer to or farther away from the clamping seat 1, so that the elastic deformation portion 10' of the clamping seat 1 undergoes elastic deformation to change the inner diameter of the clamping channel 100, thereby achieving tool clamping or release, and the coupling portion 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 toward the clamp seat 1, the side of the clamp seat 1 close to the coupling portion 10a is pulled so that the elastic deformation portion 10' is elastically deformed to 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 elastic deformation portion 10' is released, thereby restoring the normal state of the clamping channel 100 and releasing the clamping of the tool n. The user can install or remove the tool n from above. The tool n can be a cutter such as Figure 7 As shown, it can of course also be other supporting tools such as drawing pens.

[0062] In this embodiment, the position setting of the elastic deformation part 10 ′ relative to the coupling part 10 a is consistent with the setting requirements of the elastic deformation part 10 ′ relative to the coupling groove 10 in this application. For details, please refer to the relevant content of the elastic deformation part 10 ′ relative to the coupling groove 10 .

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

[0064] The tool clamp of this embodiment constructs an elastic deformation portion 10' on the side wall of the clamping base 1 at a preset distance relative to the coupling portion 10a, and utilizes the elastic deformation characteristics of the elastic deformation portion 10' by manipulating the locking control 2 to change the size of the inner diameter of the clamping channel 100 to achieve tool clamping or release, thereby reducing the parts of the tool clamp and simplifying the structure.

[0065] In this embodiment, the elastic deformation portion 10 ′ may also be formed by a structure in which the thickness of the side wall of the clamping seat 1 is reduced, so that the elastic deformation of this portion is greater than that of the adjacent portions.

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

[0067] On the other hand, the clamping seat 1 is provided with a flexible interlayer 104, the interior of which constitutes the clamping channel 100. The material selection of the flexible interlayer 104 can be known from other embodiments, such as silicone, rubber, resin and other materials that can increase the clamping friction.

[0068] Specifically, the clamping seat 1 is made of plastic material, and the flexible interlayer 104 is formed in the clamping seat 1 by secondary injection molding. Of course, it can also be made in parts and then assembled. The specific manufacturing method is the same or similar to 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 101.

[0070] In other embodiments, the flexible interlayer 104 covers the inner side of the coupling slot 10 but does not extend into the coupling slot 10 .

[0071] refer to Figures 7 to 9 Another solution of the coupling portion 10a is that the clamping base 1 is provided with a vertical coupling groove 10, and the coupling groove 10 is coated or filled with a flexible material (not shown), and the flexible material and the coupling groove 10 constitute the coupling portion 10a. It is understandable that the flexible material of this solution can be fixed to the coupling groove 10 by injection molding, bonding, etc.

[0072] Another solution of the coupling part 10a (not shown) is that the coupling part 10a is an elastically deformable structure formed by reducing the thickness of the side wall of the clamping seat 1. As in other embodiments of the present application, the elastic deformation part 10' is constructed in such a way that the thickness of the coupling part 10a is as thin as possible.
