Technical Field

[0001] This utility model relates to the field of deep groove machining technology, and in particular to a tool with an extended shank and a tool. Background Technology

[0002] During deep groove machining, the cutting resistance is high, which makes it impossible for standard tools to meet the machining requirements. Therefore, it is necessary to equip the tool holder with an extended handle.

[0003] In existing technologies, the extended shank of the cutting tool is connected to the tool body by bolts. However, due to the excessive cutting resistance during deep grooving, the bolt structure alone cannot fix the tool shank, resulting in insufficient stability and reliability. This leads to a decrease in the yield rate of deep grooving and easy damage to the cutting tool. Utility Model Content

[0004] The purpose of this utility model is to provide a tool with an extended shank and a tool, wherein the extended shank provides a more secure fixation for the tool holder and results in a higher yield rate for deep groove machining.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-2 As shown, this utility model provides a tool shank extension for extending the tool shank 100. The tool shank extension includes a main body 1, a locking member 2, and a positioning member 3. The main body 1 is elongated and has a locking position where the tool shank 100 can pass through. The main body 1 has a locking hole, and the locking member 2 is configured to pass through the locking hole and be screwed to the inner wall of the locking hole, pressing the tool shank 100 against the main body 1. The main body 1 has a positioning hole, and the tool shank 100 has an alignment hole. When the tool shank 100 is in the locking position, the positioning member 3 can pass through the positioning hole and extend into the alignment hole.

[0035] The elongated body 1 can extend the tool holder 100 so that the tool can complete the deep groove machining operation. When the tool holder 100 is in the locked position, the positioning member 3 can pass through the positioning hole and extend into the alignment hole to prevent the tool holder 100 from sliding under the action of cutting resistance and ensure the accuracy of the operation. The locking member 2 screwed to the body 1 can pass through the locking hole and press the tool holder 100 against the body 1.

[0036] Specifically, the main body 1 has a through-hole fixing groove, with a locking position located in the fixing groove, and both the locking hole and the positioning hole connected to the fixing groove; or, the main body 1 has a through-hole fixing hole, with a locking position located in the fixing groove, and both the locking hole and the positioning hole connected to the fixing hole. With these configurations, the main body 1 can have a fixing groove for the installation and removal of the tool holder 100, or a fixing hole for a more secure connection between the main body 1 and the tool holder 100.

[0037] Specifically, the main body 1 includes a clamping part 11 and a handheld part 12, with a locking position disposed on the clamping part 11. The handheld part 12 is cylindrical and connected to the clamping part 11. The projected area of ​​the handheld part 12 along the length of the main body 1 is smaller than that of the clamping part 11 along the length of the main body 1. With this design, the clamping part 11 is thickened for better stability during operation, and the smaller projected area of ​​the handheld part 12 along the length of the main body 1 facilitates gripping and reduces hand fatigue for the worker.

[0038] Specifically, the handle 12 is provided with multiple anti-slip surfaces at intervals, and these anti-slip surfaces are flat. The aforementioned anti-slip surface design and flat structure make it easier for workers to hold the handle.

[0039] More specifically, a first anti-slip structure is provided on the handgrip 12. The provision of the first anti-slip structure can increase the friction between the handgrip 12 and the worker's hand.

[0040] More specifically, the first anti-slip structure can be an anti-slip mat, such as a rubber mat; or, the first anti-slip structure can be an anti-slip protrusion, which can be dot-shaped protrusions or textured protrusions of any shape, as long as it can increase the contact friction between its location and the worker's hand. Its specific form is similar to existing technology, and is not specifically limited in this embodiment.

[0041] Specifically, the main body 1 is provided with a locking groove 13, and a locking hole is connected to the locking groove 13. The bottom of the locking groove 13 is flat. The locking groove 13 is designed to accommodate the part of the locking member 2 that protrudes from the main body 1.

[0042] In this embodiment, the locking element 2 is an M10 bolt commonly used in the art. In other embodiments, the locking element 2 can be adjusted to other types of bolts, which is not limited here.

[0043] Specifically, the main body 1 is provided with a positioning groove 14, and a positioning hole is connected to the positioning groove 14. The bottom of the positioning groove 14 is flat. The positioning groove 14 is provided to accommodate the part of the positioning member 3 that extends out of the main body 1.

[0044] In this embodiment, the diameter of the positioning element 3 is 5mm. In other embodiments, the diameter of the positioning element 3 can be adjusted according to actual needs, and no specific limitation is made here.

[0045] More specifically, the positioning element 3 is provided with a second anti-slip structure. The provision of the aforementioned second anti-slip structure can increase the contact friction between the positioning element 3 and the worker's hand or between the positioning element 3 and the inner wall of the positioning hole.

[0046] More specifically, the second anti-slip structure can be an anti-slip mat, such as a rubber mat; or, the second anti-slip structure can be an anti-slip protrusion, which can be a dotted protrusion or a textured protrusion of any shape, as long as it can increase the contact friction between its location and the worker's hand or the inner wall of the positioning hole. Its specific form is similar to existing technology and is not specifically limited in this embodiment.

[0047] Specifically, multiple locking elements 2 are spaced apart; and / or multiple positioning elements 3 are spaced apart. These arrangements ensure that the force on the locking elements 2 and / or positioning elements 3 is more even, thereby improving the stability of the tool holder 100.

[0048] In other embodiments, the number and spacing of the locking member 2 and / or the positioning member 3 can be adjusted according to the size of the tool holder 100, and no specific limitation is made here.

[0049] This embodiment also provides a cutting tool, which includes a handle 100 and the aforementioned extended handle. This cutting tool possesses all the beneficial effects of the aforementioned extended handle, which will not be elaborated further here.
