[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0021] Please refer to Figures 1-4 ;

[0022] A high-strength alloy high-speed cutting tool, comprising a cutter body 1 and a connecting barrel 2, the connecting barrel 2 is sleeved on the cutter body 1, the end of the connecting barrel 2 away from the cutter body 1 is a connecting end, the connecting end of the connecting barrel 2 can be connected with a mechanical main shaft, the outer wall of the connecting barrel 2 is provided with a clamping groove 3, in the embodiment, the number of clamping grooves 3 can be two symmetrical clamping grooves 3, or one clamping groove 3, the embodiment does not limit this, the outer wall of the cutter body 1 is provided with a mounting groove 4, the number of mounting grooves 4 is consistent with the number of clamping grooves 3, the cutter body 1 is provided with a moving block 5 that can move along the groove wall of the mounting groove 4, the side of the moving block 5 away from the mounting groove 4 is provided with a clamping block 6, the clamping block 6 can be clamped with the clamping groove 3, that is, when the moving block 5 moves towards the groove bottom of the moving groove, the moving block 5 drives the clamping block 6 to move away from the clamping groove 3, when the moving block 5 moves away from the groove bottom of the moving groove, the moving block 5 will drive the clamping block 6 to clamp with the clamping groove 3, and then quickly connect the cutter body 1 with the connecting barrel 2, in addition, in the embodiment, the moving block 5 is provided with a push rod 7, the moving block 5 is hinged with the push rod 7, the push rod 7 can push the moving block 5 to slide with the groove wall of the mounting groove 4, the outer wall of the cutter body 1 is also provided with a containing groove 8 communicating with the mounting groove 4, the containing groove 8 can be used for containing the push rod 7.

[0023] Specifically, in the initial state, the connecting sleeve is sleeved on the tool body 1, the clamping block 6 is clamped with the clamping groove 3, and the push rod 7 is located in the accommodating groove 8. Assuming that the tool body 1 needs to be replaced due to long-term use, the operator can manipulate the push rod 7. In the first step, the push rod 7 is pushed out of the accommodating groove 8, and at the same time, the push rod 7 rotates relative to the moving block 5 until the length direction of the push rod 7 is the same as the moving direction of the moving block 5. In the second step, the operator moves the moving block 5 towards the bottom of the installation groove 4 by pushing the push rod 7, at which time the clamping block 6 is disengaged from the clamping groove 3, and the tool body 1 can be easily removed. In the third step, the operator first processes the moving block 5, that is, pushes the moving block 5 to abut against the bottom of the installation groove 4, and then inserts the new tool body 1 into the connecting barrel 2, and reversely moves the moving block 5 to make the moving block 5 drive the clamping block 6 to clamp with the clamping groove 3, thereby fixing the tool body 1 and the connecting barrel 2. Through the clamping of the clamping groove 3 and the clamping block 6, the tool body 1 and the connecting barrel 2 are quickly inserted, and the use efficiency is improved. In addition, since the push rod 7 can rotate relative to the moving block 5 after use, the push rod 7 is rotated into the installation groove 4, which reduces the air resistance of the push rod 7 in high-speed rotation, and at the same time, reduces the possibility of touching the operator when the push rod 7 rotates at high speed, thereby improving the safety performance of the device.

[0024] In this embodiment, a plurality of springs 9 are arranged in the direction of the installation groove 4, one end of the spring 9 is fixedly connected with the bottom of the installation groove 4, and the other end of the spring 9 is fixedly connected with the moving block 5.

[0025] Specifically, when the operator performs the disengagement operation of the connecting sleeve and the tool body 1, the push rod 7 is pushed to make the spring 9 shrink and deform, and then the clamping groove 3 and the clamping block 6 are disengaged. When installing the new tool body 1, the push rod 7 is first pushed to make the spring 9 shrink and deform, then the connecting sleeve is sleeved on the tool body 1, the clamping block 6 is aligned with the clamping groove 3, and then the push rod 7 is loosened. The spring 9 is stretched under the action of the elastic force, the moving block 5 is moved away from the bottom of the installation groove 4, the clamping block 6 is clamped with the clamping groove 3, and the quick replacement of the connecting sleeve and the tool body 1 is completed.

[0026] In this embodiment, the surface area of the clamping block 6 away from the clamping groove 3 is the same as the area of the bottom groove wall of the clamping groove 3, and the clamping block 6 is a rectangular clamping block 6, so that the clamping groove 3 and the four side surfaces of the clamping block 6 are tightly connected, preventing gaps from causing instability of the tool body 1.

[0027] In the embodiment, the pushing rod 7 is provided with a cylinder 10 and a sliding rod 11, the moving block 5 is provided with a groove communicated with the cylinder 10, the sliding rod 11 is in sliding connection with the inner wall of the cylinder 10, the sliding rod 11 can be inserted into the groove, further, the pushing rod 7 is provided with an avoiding hole 14, the sliding rod 11 is provided with a poking block, the poking block is in fixed connection with the sliding rod 11, the poking block is in sliding connection with the hole wall of the avoiding hole, the cutter body 1 is provided with a placing groove 15 communicated with the accommodating groove 8 for accommodating the poking block, the outer wall of the pushing rod 7 is provided with a clamping hole 16 communicated with the avoiding hole 14, the clamping hole 16 can be clamped with the poking block.

[0028] Specifically, when the operator needs to separate the cutter body 1 from the connecting sleeve, the pushing rod 7 is rotated to the length direction of the pushing rod 7 being the same as the moving direction of the moving block 5, then the poking block is poked to make the poking block drive the sliding rod 11 to move towards the direction of the groove, and then the sliding rod 11 is inserted into the groove, at this time, the poking block reaches the side of the clamping hole 16, the poking block is rotated to be clamped with the clamping hole 16, and then the operator can push the moving block 5 through the pushing rod 7.
