DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0023] Reference Figure 4 Limiting component 7 includes mounting block 71, the number of mounting block 71 is two, the top of mounting block 71 is fixedly connected with the top of fastener 5, the inner side of mounting block 71 is slidably connected with limiting block 72, the outer side of limiting block 72 is fixedly connected with spring two 73, the outer side of spring two 73 is fixedly connected with the inside of mounting block 71.

[0024] As a kind of technical optimization scheme of the utility model, by setting limiting component 7, when the insertion block 81 continues to move up and drives the clamping groove 11 to move to the position of limiting block 72, spring two 73 in compression state will start to reset action, under the action of elasticity, spring two 73 will push limiting block 72 to move towards the direction of clamping groove 11, to realize the close insertion of limiting block 72 and clamping groove 11, in this way, this explicit state change provides clear signal for operator, so that it can accurately judge whether it has already had the corresponding condition to carry out next operation, to effectively improve the standardization and discernibility of entire operation process.

[0025] Reference Figure 4 Fixed mechanism 8 includes insertion block 81, the outside of insertion block 81 is slidably connected with the inside of fastener 5, the top of insertion block 81 is fixedly connected with connecting plate 82, the top of connecting plate 82 is fixedly connected with pull ring 83, the left side and right side of connecting plate 82 are both fixedly connected with reinforcing plate 84, the bottom of reinforcing plate 84 is fixedly connected with tension spring 85, the bottom of tension spring 85 is fixedly connected with the inside of fastener 5.

[0026] As a technical optimization of this utility model, by setting a fixing mechanism 8, when it is necessary to replace the cutting tool 3, this series of actions can be initiated by pulling the pull ring 83. After the pull ring 83 is subjected to force, it will drive the connecting plate 82 connected to it to move upward. The upward movement of the connecting plate 82 will further drive the plug block 81 to move upward synchronously. During this process, the tension spring 85 will also be stretched. As the plug block 81 moves upward, its bottom will first disengage from the fitting block 9. Then, the plug block 81 continues to move upward until it no longer contacts the inside of the cutting tool 3. Thus, the preparation steps before the replacement operation of the cutting tool 3 are completed more accurately and efficiently, which greatly improves the smoothness and controllability of the cutting tool 3 replacement process.

[0027] refer to Figure 4 The snap-fit ​​block 2 has a fixed internal connection to the fitting block 9, and the top of the fitting block 9 is inserted into the cutting tool 3.

[0028] As a technical optimization of this utility model, by setting the fitting block 9, when the cutting tool 3 is installed, the fitting block 9 can be precisely inserted into the groove on the surface of the cutting tool 3, thereby achieving rapid and accurate positioning of the cutting tool 3 and ensuring the efficiency and accuracy of the installation process.

[0029] refer to Figure 4 A permanent magnet 10 is fixedly connected inside the interlocking block 9, and the interlocking block 9 is located to the left of the spring 4.

[0030] As a technical optimization of this utility model, by setting a permanent magnet 10, when the plug block 81 comes into contact with the permanent magnet 10, the magnetic force released by the permanent magnet 10 can strongly attract the bottom of the plug block 81. The existence of this attraction force makes the plug block 81 stable in the corresponding position, greatly reducing the possibility of instability such as displacement, and thus effectively ensuring the stability and accuracy of the cooperation of related components and the operation of the overall device.

[0031] refer to Figure 4 The front and rear sides of the plug-in block 81 are provided with slots 11, and the inside of the slots 11 is plugged into the inside of the limiting block 72.

[0032] As a technical optimization of this utility model, by setting the slot 11, during the upward movement of the insertion block 81, the precise insertion action between the limiting block 72 and the slot 11 can provide clear and intuitive feedback to the operator, so that the operator can know the separation state between the insertion block 81 and the cutting tool 3, thereby making it easier for the operator to better grasp the progress of the entire operation process.

[0033] refer toFigure 2 A folded waterproof cloth 12 is fixedly connected to the right side of the fastener 5, and the right side of the folded waterproof cloth 12 is fixedly connected to the surface of the frame 1.

[0034] As a technical optimization of this utility model, by setting the folded waterproof cloth 12, an effective protective measure can be provided for the spring-4, preventing the debris generated during the cutting operation from splashing everywhere, thereby avoiding the adverse effects of these debris on the spring-4, ensuring that the spring-4 is always in good working condition and maintaining its normal performance.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to replace the cutting tool 3, this series of actions can be initiated by pulling the pull ring 83. After the pull ring 83 is subjected to force, it will drive the connecting plate 82 connected to it to move upward. The upward movement of the connecting plate 82 will further drive the insertion block 81 to move upward synchronously. During this process, the tension spring 85 will also be stretched. As the insertion block 81 moves upward, its bottom will first disengage from the fitting block 9. Then, the insertion block 81 continues to move upward until it is in contact with the inner part of the cutting tool 3. The parts no longer make contact. When the insertion block 81 continues to move upward, it will cause the slot 11 to move to the position of the limiting block 72. At this time, the spring 73, which was originally in a compressed state, will begin to reset. Under the action of the elastic force, the spring 73 will push the limiting block 72 towards the slot 11, thereby achieving a tight insertion between the limiting block 72 and the slot 11. After completing the above steps, the lever 6 is used to apply external force to push the fastener 5 to move to the right. During the process of the fastener 5 moving to the right, it will exert a squeezing force on the spring 4. After the fastener 5 and the cutting tool 3 are completely disengaged, the cutting blade can be replaced smoothly.

[0036] In summary, this clamping device for easy tool replacement in cutting tool production, through the coordinated use of frame 1, snap-fit ​​block 2, cutting tool 3, spring 4, fastener 5, lever 6, limit assembly 7, and fixing mechanism 8, solves the problem that when carrying out cutting tool replacement operations, the fastening bolts must be removed before subsequent operations can be carried out. However, traditional fastening bolts may require multiple tightening with special tools to remove, which is time-consuming. This situation makes the entire cutting tool replacement process quite cumbersome and complicated.
