The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] The first embodiment of this application is:

[0021] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of an adjustable high-precision cutting tool with multiple depth dimensions. Figure 2 This is a front view of an adjustable high-precision cutting tool with multiple depth dimensions. Figure 3 This is a schematic diagram of the installation of the positioning cylinder. This utility model provides an adjustable high-precision cutting tool with multiple depth dimensions: it includes a tool holder 101, an upper blade holder 102, a lower blade holder 103, and an adjustment device. The adjustment device includes a positioning cylinder 104, a protective cover plate 105, a resistance component, an auxiliary component, and a carrying component. The resistance component includes a protective sleeve 106 and a rubber ball 107. The auxiliary component includes an anti-slip pad 108 and a mating component. The mating component includes a metal ring 109 and a pressing block 110. The aforementioned solution addresses the issue of the fixed length of the tool holder 101, which prevents adjustment based on actual conditions and necessitates the replacement of different sized tool holders. This cumbersome and inconvenient operation is a consequence of the fixed length of the tool holder 101. The solution allows for adjustable length of the tool holder 101, enabling adjustments based on actual conditions and eliminating the need for replacements. This simplifies operation, improves ease of use, and facilitates the carrying of the tool.

[0022] In this specific embodiment, the upper blade clamping body 102 is fixedly connected to the blade shank 101 and located on one side of the blade shank 101. The lower blade clamping body 103 is fixedly connected to the blade shank 101 and located on one side of the blade shank 101. The blade shank 101 has a blade shank 101 slot, which includes a blade clamping slot and a deformation slot. The blade shanks 101 on both sides of the slot are the upper blade clamping body 102 and the lower blade clamping body 103. The upper blade clamping body 102 has a positioning protrusion arranged along the axial direction of the blade shank 101. The top of the blade has a positioning protrusion arranged along the width of the blade. The blade is positioned radially along the tool shank 101 and inserted into the blade clamping slot. A fastening screw connects the upper blade clamping body 102 and the lower blade clamping body 103 to hold the blade. When the blade is at different radial positions on the tool shank 101, the positioning protrusion can be embedded into different positioning slots. In use, the fastening screw is loosened, allowing the blade to move. The blade is removed from the front end of the tool shank 101, its position is changed so that other positioning slots align with the positioning protrusions, and then the blade is reinstalled and the fastening screw is tightened. The length of the cutting edge protruding from the tool shank 101 changes, thus adjusting the maximum machining depth of the tool. All of the above are existing technologies.

[0023] The positioning cylinder 104 is threadedly connected to the tool bar 101 and located on one side of the tool bar 101. The protective cover plate 105 is fixedly connected to the positioning cylinder 104 and located on one side of the positioning cylinder 104. The resistance component is disposed on the tool bar 101, the auxiliary component is disposed on the positioning cylinder 104, and the carrying component is disposed on the protective cover plate 105. The positioning cylinder 104 has a tubular structure, and its inner diameter is adapted to the diameter of the tool bar 101. The tool bar 101 is placed inside the positioning cylinder 104, and the inner surface of the positioning cylinder 104 has an inner... The tool holder 101 has an external thread on its outer surface that matches the internal thread, so that when the positioning cylinder 104 is rotated, the positioning cylinder 104 can move along the axial direction of the tool holder 101 under the threaded drive of the tool holder 101, thereby changing the distance between the tool holder 101 and the positioning cylinder 104. This allows the positioning cylinder 104 to replace the tool holder 101, thereby adjusting the length of the tool holder 101. The bottom end of the positioning cylinder 104 is welded with the protective cover plate 105, which makes the bottom of the positioning cylinder 104... The opening is closed, thereby restricting the movement of the positioning cylinder 104 on the tool bar 101. The resistance component is located at the top of the tool bar 101, facilitating the application of force to the tool bar 101. The auxiliary component is located on the positioning cylinder 104, facilitating the application of force to the positioning cylinder 104. The resistance component and the auxiliary component cooperate to facilitate the operator's adjustment of the distance between the tool bar 101 and the positioning cylinder 104. The carrying device is located on the lower surface of the protective cover plate 105. The inclusion of components facilitates carrying the tool. When it is necessary to extend the cutting distance, the resistance component and the auxiliary component work together to rotate the tool holder 101 relative to the positioning cylinder 104. Driven by the rotation of the positioning cylinder 104, the positioning cylinder 104 moves along the axial direction of the tool holder 101, thereby allowing the length of the tool holder 101 to be adjusted according to actual needs. This eliminates the need to replace the tool holder 101 with different sizes, simplifying operation and making it convenient to use.

[0024] Secondly, the protective sleeve 106 is fixedly connected to the blade 101 and located on one side of the blade 101; the rubber ball 107 is fixedly connected to the protective sleeve 106 and located on one side of the protective sleeve 106. The protective sleeve 106 is sleeved and fixed to the top of the outer surface of the blade 101. The protective sleeve 106 is soft in texture, and the rubber balls 107 are fixedly arranged in an array at the same interval on the surface of the protective sleeve 106. The rubber balls 107 are made of soft rubber material and have the characteristics of anti-slip and wear resistance. The rubber balls 107 and the protective sleeve 106 provide a point of force for the operator's hands, which can increase the resistance between the operator and the blade 101, making it easier to adjust the length of the blade 101 and making it easier to pick up the blade 101.

[0025] Meanwhile, the anti-slip pad 108 is fixedly connected to the positioning cylinder 104 and located on one side of the positioning cylinder 104; the mating component is disposed on one side of the positioning cylinder 104; there are four anti-slip pads 108, which are arranged on the positioning cylinder 104 with the center of the positioning cylinder 104 as the starting point, and spaced 90 degrees apart from each other. The anti-slip pads 108 are made of high-polymer sponge material, which has the characteristics of anti-slip and wear resistance, so that when the operator adjusts the length of the tool holder 101, one hand can pass through... The rubber ball 107 and the protective sleeve 106 hold the blade 101, while the other hand holds the positioning cylinder 104 by contacting the anti-slip pad 108. This increases the resistance between the operator's hand and the positioning cylinder 104 and the blade 101, making it easier to rotate the blade 101 and the positioning cylinder 104. The mating component is provided on the positioning cylinder 104, which makes it easier to hold the positioning cylinder 104 when using this tool.

[0026] In addition, the metal ring 109 is fixedly connected to the positioning cylinder 104 and located on one side of the positioning cylinder 104; the pressing block 110 is fixedly connected to the metal ring 109 and located on one side of the metal ring 109. The metal ring 109 is sleeved and welded to the bottom of the outer surface of the positioning cylinder 104. The pressing block 110 is welded to the side of the metal ring 109. The outer surface of the pressing block 110 has a certain curvature, which conforms to ergonomics, so that the operator's fingers can be placed on the pressing block 110, thereby cooperating with the anti-slip pad 108 to facilitate the picking up of the positioning cylinder 104.

[0027] When using an adjustable high-precision cutting tool with multiple depth dimensions according to this embodiment, if it is necessary to extend the cutting tool's working distance, the operator holds the cutting tool shank 101 with one hand through the rubber ball 107 and the protective sleeve 106, and holds the positioning cylinder 104 with the anti-slip pad 108 with the other hand. Then, rotating the two together causes the positioning cylinder 104 to move along the axial direction of the cutting tool shank 101 under the threaded drive of the rotation. This allows the length of the cutting tool shank 101 to be adjusted according to the actual situation, eliminating the need to replace the cutting tool shank 101 with different sizes. The operation is simple and convenient.

[0028] The second embodiment of this application is as follows:

[0029] Based on the first embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the overall structure of an adjustable high-precision tool with multiple position depth dimensions in the second embodiment. The carrying component in this embodiment includes a lifting ring 201 and a rubber sleeve 202.

[0030] In this specific embodiment, the lifting ring 201 is fixedly connected to the protective cover plate 105 and located on one side of the protective cover plate 105; the rubber sleeve 202 is detachably connected to the lifting ring 201 and located on one side of the lifting ring 201. The lifting ring 201 is welded to the bottom end of the protective cover plate 105. The lifting ring 201 has a ring-shaped structure. The lifting ring 201 provides a point of leverage for the operator, making it easier for the operator to pick up the protective cover plate 105 through the lifting ring 201, thereby facilitating the overall handling of the knife. The rubber sleeve 202 is fitted onto the lifting ring 201. The rubber sleeve 202 is made of soft rubber material, which has anti-slip and wear-resistant characteristics, and good toughness. The rubber sleeve 202 makes it easier for the operator to pick up and carry the knife through the lifting ring 201, and the operation is simple.

[0031] When using an adjustable high-precision tool with multiple depth dimensions in this embodiment, during the process of carrying the tool, the operator's hand uses the rubber sleeve 202 to pick up the lifting ring 201, which generates greater resistance between the operator's hand and the lifting ring 201, thereby facilitating the carrying of the tool and simplifying the operation.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
