[0003] At present, existing PCB cutters are generally stored in a cutter box. However, during transportation, the PCB cutter may collide with the cutter box, causing the blade of the PCB cutter to collide with the cutter box, resulting in damage to the blade of the PCB cutter. Based on this, a blade protection cover for a PCB cutter is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a blade protection cover for a PCB tool with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A blade protection cover for a PCB tool comprises a storage tube, a tube cap and a tool. The inner bottom of the storage tube is fixedly connected to blade protection cotton, the inner top of the tube cap is fixedly connected to tool rod protection cotton, a vibration damping mechanism is fixedly connected inside the storage tube, the tool is stored in the vibration damping mechanism, and the top of the tool is located in the tool rod protection cotton.

[0007] As a further optimization scheme of the present invention, the vibration damping mechanism includes a fixed ring fixedly connected in the storage tube, the top of the fixed ring is fixedly connected with a damping rod, the outer surface of the damping rod is sleeved with a buffer spring, the top of the damping rod is fixedly connected with a connecting ring, and the inner surface of the connecting ring is fixedly connected with a protective component.

[0008] As a further optimization solution of the present invention, the bottom of the buffer spring is fixedly connected to the top of the fixing ring, and the top of the buffer spring is fixedly connected to the bottom of the connecting ring.

[0009] As a further optimization scheme of the present invention, the protection component includes a sleeve fixedly connected in the connecting ring, the inner surface of the sleeve is fixedly connected to a protection airbag, the inner surface of the protection airbag is fixedly connected to a storage sleeve, the top of the storage sleeve is fixedly connected to a limiting plate, and the bottom of the storage sleeve is fixedly connected to a supporting ring.

[0010] As a further optimization solution of the present invention, the bottom of the limit plate is slidably connected to the top of the sleeve, the tool is placed in the storage sleeve, and the inner surface of the support ring fits the outer surface of the tool.

[0011] As a further optimization solution of the present invention, the storage tube and the tube cap are connected by threads, and the blade of the tool is located in the blade protection cotton.

[0012] The beneficial effect of the present invention is that: through the coordinated use of the vibration reduction mechanism and the protection component, during the process of transporting the PCB tool, the vibration reduction mechanism can buffer and absorb the vibration generated in the axial direction of the tool, thereby preventing the blade of the tool from directly hitting the bottom of the storage tube and causing damage to the blade of the tool, while the protection component can buffer and absorb the vibration generated by the tool in the direction perpendicular to the axial direction of the tool, thereby preventing the tool from hitting the side wall of the storage tube and causing damage to the tool, thereby providing good protection for the tool and extending the service life of the tool.

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the blade protection cover for PCB tools includes a storage tube 1, a tube cap 2 and a tool 5. The storage tube 1 is connected to the tube cap 2 by a thread, which makes it easy to open the storage tube 1. The inner bottom of the storage tube 1 is fixedly connected with a blade protection cotton 3, and the blade of the tool 5 is in the blade protection cotton 3. The setting of the blade protection cotton 3 can prevent the blade of the tool 5 from directly hitting the storage tube 1 when the tool 5 vibrates, thereby providing good protection for the blade of the tool 5. The inner top of the tube cap 2 is fixedly connected with a tool rod protection cotton 4, and a vibration damping mechanism is fixedly connected to the storage tube 1. The tool 5 is stored in the vibration damping mechanism, and the top of the tool 5 is located in the tool rod protection cotton 4. The setting of the tool rod protection cotton 4 can prevent the tool 5 from detaching from the vibration damping mechanism when the tool 5 vibrates, resulting in the blade of the tool 5 colliding with the inner wall of the vibration damping mechanism.

[0020] When using the PCB cutter, the cutter 5 can be taken out of the vibration damping mechanism by rotating and unscrewing the tube cap 2, and assembled to the PCB processing equipment to process the PCB board. When the cutter 5 needs to be stored after use, the cutter 5 is inserted into the vibration damping mechanism with the blade facing downward, and the tube cap 2 is screwed back on the storage tube 1.

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the vibration damping mechanism includes a fixed ring 6 fixedly connected to the storage tube 1, the top of the fixed ring 6 is fixedly connected to the damping rod 7, the outer surface of the damping rod 7 is sleeved with a buffer spring 13, the top of the damping rod 7 is fixedly connected to the connecting ring 8, the inner surface of the connecting ring 8 is fixedly connected to the protection component, the bottom of the buffer spring 13 is fixedly connected to the top of the fixed ring 6, the top of the buffer spring 13 is fixedly connected to the bottom of the connecting ring 8, the protection component includes a sleeve 9 fixedly connected to the connecting ring 8, the inner surface of the sleeve 9 is fixedly connected to the protection airbag 10, the inner surface of the protection airbag 10 is fixedly connected to the storage sleeve 11, the top of the storage sleeve 11 is fixedly connected to the limiting plate 12, the bottom of the storage sleeve 11 is fixedly connected to the supporting ring 14, the bottom of the limiting plate 12 is slidably connected to the top of the sleeve 9, the tool 5 is placed in the storage sleeve 11, and the inner surface of the supporting ring 14 fits the outer surface of the tool 5.

[0022] When storing the tool 5, the blade of the tool 5 is placed downward and inserted into the storage sleeve 11, and the tool 5 is fitted on the inner surface of the supporting ring 14. Then the tube cap 2 can be screwed onto the storage tube 1. During transportation, when the tool 5 generates axial vibration, the damping rod 7, the buffer spring 13, the connecting ring 8, the tool rod protection cotton 4 and the protective airbag 10 cooperate to buffer and absorb the axial vibration generated by the tool 5. When the tool 5 generates vibration perpendicular to the axial direction, the protective airbag 10 will buffer and absorb the vibration perpendicular to the axial direction generated by the tool 5, thereby avoiding collision between the tool 5 and the storage tube 1, which may cause damage to the tool 5. This well protects the tool 5 and extends the service life of the tool 5.

[0023] Furthermore, when the cutter 5 vibrates in the axial direction, the blade of the cutter 5 squeezes the blade protection cotton 3 but does not completely compress the blade protection cotton 3 , thus causing no damage to the blade of the cutter 5 .

[0024] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
