Description

Technical Field

[0001] The utility model relates to the technical field of tool components, in particular to an assembled heat shrinkable tool handle. Background Art

[0002] The principle of the heat shrinkable tool holder is to use the difference in thermal expansion coefficient between the tool holder (special stainless steel) and the tool (carbide) to clamp the tool with high strength and precision. The tool holder material uses special stainless steel for heat shrinking with a large thermal expansion coefficient, which achieves low-temperature heat shrinking at 300°C. A simple hot air heating device using an industrial hair dryer is used. A collection of 3,500 tool holders of different shapes can be used for all processing from high-speed and fine machining to heavy cutting, milling, drilling, reaming, etc.

[0003] The utility model with prior art publication number CN219944652U relates to a heat-shrinkable tool handle. By setting a positioning clamping structure and cooperating with an L-shaped block and several straight grooves of different lengths on the tool head, the user can select the corresponding installation straight groove according to the insertion length that matches the heat-shrink tool handle and the tool head, thereby achieving the best installation effect of the tool head. At the same time, the L-shaped block and the straight groove are distributed in a mirror-symmetrical manner, so that the force applied to the tool head remains balanced when the tool head rotates.

[0004] However, the above-mentioned heat shrink tool handle still has the following problems when in use: when it is used for the matching and assembly of tools, it has several straight grooves of different lengths to match the assembled tools. It can only adapt to tools corresponding to several straight grooves, and cannot be linearly adjusted to flexibly adapt to tools within a certain length range. Therefore, its adaptability to the assembly of different tools is poor. Utility Model Content
