Detailed implementation manners

[0026] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0027] In this embodiment, referring to Figures 1-6 , a detachable tool head that can be quickly disassembled in a specific implementation thereof includes a tool holder 1. A rotatable tool rod 2 is installed on the tool holder 1. Blades 3 and a transmission block 4 are respectively provided at both ends of the tool rod 2. A quick-release assembly for cooperating with the tool rod 2 is provided at one end of the transmission block 4. The quick-release assembly includes a steel ball 5 installed in the transmission block 4 and a sliding sleeve 6 installed on the outer diameter of the transmission block 4. The sliding sleeve 6 is slidably matched with the transmission block 4 through a return spring 7. The tool rod 2 is provided with a fixing groove 8 for cooperating with the steel ball 5. A through hole for installing the steel ball 5 is provided in the transmission block 4. A clamp for cooperating with the return spring 7 is provided at one end of the transmission block 4. When disassembly is required, by pushing the sliding sleeve 6, the originally tightened steel ball 5 can be loosened, and then the transmission block 4 can be easily removed. Subsequently, the tool rod 2 becomes loose without the fixation of the transmission block 4, and at this time, the tool rod 2 can be conveniently disassembled. Such a design simplifies the disassembly process, improves the convenience and efficiency of operation. And it avoids the situation that the hand accidentally touches the blade 3 and gets injured due to twisting and disassembly during installation or disassembly.

[0028] Furthermore, the tool rod 2 is provided with a fixing block 9 for installing the blade 3. Through the fixing block 9, the angle of the blade 3 is restricted. When the tool rod 2 rotates, due to the stabilizing effect of the fixing block 9, the blade 3 rotates along with the rotation of the tool rod 2, thereby playing a role in cutting or processing. A gasket is provided at one end of the fixing block 9. The blade 3 is firmly pressed on the fixing block 9 by cooperating with the gasket through a screw.

[0029] Furthermore, one end of the tool shank 2 is provided with a key block 10, and the transmission block 4 is provided with a key groove 11 that cooperates with the key block 10. Through the cooperation of the key block 10 and the key groove 11, the tool shank 2 can rotate synchronously with the rotation of the transmission block 4. When operating at high speed or under a large cutting force, the cooperation of the key block 10 and the key groove 11 can effectively prevent the tool shank 2 from axially moving or circumferentially slipping, ensuring machining accuracy and safety.

[0030] Furthermore, the tool holder 1 is provided with a bushing 12 for installing the tool shank 2, and one end of the bushing 12 is provided with a sealing ring 13. The bushing 12 is fixed in the tool holder 1 by a threaded locking block. A plurality of bearings are installed in the bushing 12 and are in clearance fit with the tool shank 2, making the rotation of the tool shank 2 smoother and with less friction. The setting of the sealing ring 13 effectively prevents liquids and the like from leaking out from the tool shank 2, enhancing the sealing effect of the tool holder 1.

[0031] Furthermore, the tool holder 1 and the bushing 12 are provided with a limiting groove 14 and a limiting block 15 for mutual cooperation. Through the limiting groove 14 and the limiting block 15, the installation of the bushing 12 is more convenient and fast, and the bushing 12 is prevented from rotating or loosening during use, further improving the overall stability and service life.

[0032] Furthermore, the sliding sleeve 6 is provided with a boss 16 extending outward. The boss 16 makes the pushing of the sliding sleeve 6 more convenient and fast. At the same time, the design of the boss 16 also increases the contact area between the sliding sleeve 6 and the hand or tool, improving the comfort and stability during operation and reducing unnecessary troubles and potential risks caused by slipping. And the boss 16 is provided with reinforcing ribs to prevent deformation or damage of the sliding sleeve 6 during long-term use or strong pushing.

[0033] Refer to Figures 7-8 , the specific implemented wall breaker includes a base 17, a cup body 18, a cup cover 19, and a drive assembly 20 installed in the base 17. A cutter head is fixedly installed in the cup cover 19, and the cutter head and the cup cover 19 are provided with a limiting structure for mutual cooperation, so that the cutter head is fixedly installed in the cup cover 19. The drive assembly 20 is provided with a transmission groove 21 that cooperates with the cutter head. The transmission groove 21 is installed at one end of the drive assembly 20 through a pin. The cup cover 19 is installed on the cup body 18 by threaded connection, making the cup cover 19 and the cup body 18 closely combined to prevent food from splashing out during the wall breaking process. Then the cup cover 19 is aligned with the base 17 and inserted, so that the transmission groove 21 is connected and cooperates with the transmission block 4. Thus, when the drive assembly 20 drives the transmission groove 21 to rotate, the transmission groove 21 can drive the transmission block 4 to rotate together, causing the blade 3 at the other end of the tool shank 2 to rotate for wall breaking and other operations.

[0034] Further, a buckle 22 is provided on the outer side of the cup lid 19, and a clamping groove 23 for cooperating with the buckle 22 is provided on the base 17. The buckle 22 is engaged with the clamping groove 23 by rotation. Through the cooperation of the buckle 22 and the clamping groove 23, the displacement of the cup lid 19 is restricted, so that the cup lid 19 is stably locked on the base 17, avoiding loosening or falling off of the connection between the cup lid 19 and the base 17 due to the collision and cutting of the blade 3 with the ingredients in the cup body 18 during use, thereby affecting the normal use of the wall breaker.

[0035] Further, a detection component 24 is provided inside the base 17, and a pressing block 25 for cooperating with the detection component 24 is provided on the cup lid 19. When the cup lid 19 is inserted into the base 17 and locked, the pressing block 25 presses down the detection component 24, causing it to emit a signal to confirm that the cup lid 19 is correctly installed and in a locked state. This design enhances the safety of using the wall breaker, preventing the machine from being started when the cup lid 19 is not fully fixed, thereby avoiding possible splashing or safety accidents.

[0036] The beneficial effects of the present utility model: Through the cooperation of the sliding sleeve 6 and the return spring 7, the sliding sleeve 6 is slidably installed on the outer diameter of the transmission block 4, and through the cooperation of the sliding sleeve 6 and the steel ball 5, the steel ball 5 can be quickly engaged or separated from the fixing groove 8, thereby realizing the quick disassembly and installation of the cutter bar 2. It makes it more convenient and fast for users to install or disassemble the cutter bar 2. At the same time, it avoids the hand accidentally touching the sharp part of the blade 3 during installation or disassembly, resulting in injury, thereby improving the safety of use and the user experience.
