[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the elastic knife handle seat and the knife of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0016] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "center", "longitudinal", "lateral", "up", "down", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0018] See also Figures 1 to 4 The elastic tool handle seat 1 of the utility model embodiment includes a seat body 11, the seat body 11 is provided with two fixing holes 12, a clamping hole 13 is opened in the middle of the seat body 11, a fixing block 14 is arranged around the inner wall of the clamping hole 13, and the inner wall of the clamping hole 13 is also provided with two elastic devices 15 facing each other, and a convex edge 16 is arranged along the edge of the clamping hole 13.

[0019] In the above embodiment, the two fixing holes 12 provided on the seat body 11 are used to fix the tool handle seat on a machine tool or other processing equipment to ensure its stability during the working process. The clamping hole 13 in the middle of the seat body 11 is the core part of the elastic tool handle seat 1, which is used to clamp the tool handle of the tool 2. The fixing block 14 arranged around the inner wall of the clamping hole 13 can provide a certain clamping force to help fix the tool 2. The elastic device 15 facing the two positions provided on the inner wall of the clamping hole 13 is a component for realizing elastic clamping. When the tool 2 is inserted into the clamping hole 13, the elastic device 15 will be squeezed by the tool 2 and deformed. This deformation will generate a reverse clamping force to firmly fix the tool 2 in the clamping hole 13. Since the elastic device 15 has a certain elasticity, it can adapt to tool handles of different sizes and achieve wide applicability. In addition, a circle of convex edges 16 arranged along the edge of the clamping hole 13 not only enhances the structural strength of the clamping hole 13, but also can prevent the tool 2 from sliding or falling off during the processing process to a certain extent, thereby improving the safety of the work. In summary, the elastic tool handle seat 1 of the embodiment of the utility model realizes the stable clamping and adaptive adjustment of the tool 2 through the coordinated action of the fixing block 14 and the elastic device 15, thereby improving the processing accuracy and production efficiency.

[0020] See also Figures 1 to 4 In another embodiment, the elastic device 15 includes a spring 151, a ball 152 and a threaded nail 153, the spring 151 is sleeved on the threaded nail 153, the ball 152 is arranged on the spring 151, the threaded nail 153 is fixedly installed on the seat body 11, and the ball 152 faces the inner side of the seat body 11.

[0021] In the above embodiment, the threaded nail 153 is installed on the seat 11 as a fixing component, and the spring 151 is sleeved on the threaded nail 153, and its main function is to provide elasticity and restoring force. When the tool 2 is inserted into the clamping hole 13, the handle of the tool 2 will squeeze the ball 152, and the ball 152 will then compress the spring 151. Due to the elasticity of the spring 151, it will generate a corresponding reverse force according to the size and squeezing force of the tool 2. This reverse force is transmitted to the handle of the tool 2 through the ball 152, thereby achieving a stable clamping of the tool 2. The ball 152 can not only evenly transmit the force of the spring 151 to the tool 2 to prevent damage to the tool 2 or affect the clamping effect due to uneven force distribution, but also the rolling characteristics of the ball 152 can reduce friction to a certain extent, making the insertion and extraction of the tool 2 smoother.

[0022] See also Figures 1 to 4 In the second embodiment of the utility model, a limiting structure 21 is provided at the handle of the tool 2. The cross section of the limiting structure 21 is in a "concave" shape and is annularly arranged at the handle of the tool 2. It is characterized in that when the tool 2 is inserted into the clamping hole 13, the lower convex edge 211 of the limiting structure 21 abuts against the fixing block 14, the ball 152 is embedded in the groove 212 of the limiting structure 21, and the upper convex edge 213 of the limiting structure 21 covers the clamping hole 13.

[0023] In the above embodiment, when the tool 2 is inserted into the clamping hole 13, the lower convex edge 211 of the limiting structure 21 first abuts against the fixed block 14. The presence of the fixed block 14 provides an initial support and positioning for the tool 2, ensuring that the tool 2 can be correctly aligned with the center of the clamping hole 13. At the same time, the contact between the lower convex edge 211 and the fixed block 14 also helps to prevent the tool 2 from shaking or deflecting during the clamping process. As the tool 2 is further inserted, the ball 152 will be embedded in the groove 212 of the limiting structure 21. At this time, the ball 152 is subjected to the extrusion force from the tool handle, and through the action of the spring 151, a reverse clamping force is generated. Since the ball 152 is embedded in the groove 212, this clamping force can be more evenly distributed on the tool handle, improving the stability and reliability of the clamping. Finally, when the tool 2 is fully inserted into the clamping hole 13, the upper convex edge 213 of the limiting structure 21 will cover the edge of the clamping hole 13. In this way, the upper convex edge 213 of the limiting structure 21 and the edge of the clamping hole 13 together form a closed structure, further enhancing the stability of the tool 2 in the clamping hole 13. This design can not only prevent the tool 2 from sliding or falling off during the processing, but also improve the processing accuracy and safety.

[0024] See also Figures 1 to 4 In another embodiment, the handle of the tool 2 matches the shape and size of the clamping hole 13 .

[0025] In the above embodiment, this ensures that when the tool 2 is inserted into the clamping hole 13, the contact surfaces of the two can fit closely, reducing gaps and unstable factors. This close fit helps to disperse the clamping force and avoid stress concentration, thereby improving the stability and reliability of clamping.

[0026] See also Figures 1 to 4 In another embodiment, anti-slip grooves are provided between the lower convex edge 211 of the limiting structure 21 and the fixing block 14 .

[0027] In the above embodiment, the existence of the anti-slip pattern increases the friction coefficient between the lower convex edge 211 and the fixing block 14 .

[0028] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
