Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting blades, and in particular to a quick-release blade holder. Background Technology
[0002] Existing cutting blade mounting brackets are generally mounted on a single transmission rod. When a problem occurs with the cutting blade, the entire transmission rod needs to be disassembled to remove the cutting blade. This process involves disassembling many components, making disassembly and installation quite cumbersome. Furthermore, cutting blades are consumables and are easily damaged. Existing cutting blade mounting brackets cannot meet production needs. Summary of the Invention
[0003] The main objective of this invention is to provide a quick-release blade holder that uses a multi-segment cutting blade connecting rod to solve the problem of cumbersome disassembly and installation of the cutting blade.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A quick-release blade holder includes a power motor, a gearbox, a power base, a rotating base, a cutting blade connecting rod, and a cutting blade body. The output end of the gearbox is fixedly connected to the power base, and the input end of the gearbox is connected to the power motor. A cutting blade connecting rod is rotatably mounted between the power base and the rotating base. The cutting blade body is fixedly mounted on the cutting blade connecting rod. The cutting blade connecting rod includes fixed connecting rods on both sides and a cutting blade fixing rod connected between the fixed connecting rods. A cutting blade fixing seat is provided on the cutting blade connecting rod, and the cutting blade body is fixedly mounted on the cutting blade fixing seat. The two ends of the cutting blade fixing rod are respectively connected to the fixed connecting rods on both sides by detachable screws.
[0006] Furthermore, the outer ring surfaces of the connecting ends of the cutting blade fixing rod and the fixing connecting rod are provided with external threads, and a baffle is screwed into the external thread. A limit sleeve is slidably fitted between the baffles, and the limit sleeve is fitted at the connection between the cutting blade fixing rod and the fixing connecting rod.
[0007] Furthermore, a limiting spring is provided on one side of the limiting sleeve, and the two ends of the limiting spring are respectively connected to the side end face of the baffle and the end face of the limiting sleeve.
[0008] Furthermore, when the limiting sleeve compresses the spring, the screw used to connect the cutting blade fixing rod and the fixed connecting rod is exposed. When it is released and subjected to force, the spring covers the connection between the fixed connecting rod and the cutting blade fixing rod with the limiting sleeve, and the two ends of the limiting sleeve extend to the non-connection points of the fixed connecting rod and the cutting blade fixing rod, respectively.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] This invention features a multi-segment cutting blade connecting rod. When the cutting blade needs to be replaced, it can be done simply by unlocking the connecting rod. Furthermore, the multi-segment cutting blade connecting rod is shorter when not assembled, making it more convenient for transportation and storage. Attached Figure Description

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention. Figure 1-3 As shown, a quick-release blade holder includes a power motor 1, a gearbox 2, a power base 3, a rotating base 4, a cutting blade connecting rod 5, and a cutting blade body 6. The output end of the gearbox 2 is fixedly connected to the power base 3, and the input end of the gearbox 2 is connected to the power motor 1. The cutting blade connecting rod 5 is rotatably mounted between the power base 3 and the rotating base 4. The cutting blade body 6 is fixedly mounted on the cutting blade connecting rod 5. The cutting blade connecting rod 5 includes fixed connecting rods 7 on both sides and a cutting blade fixing rod 8 connected between the fixed connecting rods 7. The cutting blade connecting rod is provided with a cutting blade fixing seat, and the cutting blade body 6 is fixedly mounted on the cutting blade fixing seat. The two ends of the cutting blade fixing rod 8 are respectively connected to the fixed connecting rods 7 on both sides by detachable screws 9.
[0016] The outer ring surfaces of the connecting ends of the cutting blade fixing rod 8 and the fixed connecting rod 7 are both provided with external threads. A baffle 10 is screwed into the external thread. A limit sleeve 11 is slidably fitted between the baffles 10 and the limit sleeve 11 is fitted on the cutting blade fixing rod 8 and the fixed connecting rod 7.
[0017] The limiting sleeve 11 has a limiting spring on one side, and the two ends of the limiting spring are connected to the side end face of the baffle 10 and the end face of the limiting sleeve 11, respectively.
[0018] When the limiting sleeve 11 compresses the spring, the screw 9 used to connect the cutting blade fixing rod 8 and the fixed connecting rod 7 is exposed. When released and under force, the spring covers the connection between the fixed connecting rod 7 and the cutting blade fixing rod 8 with the limiting sleeve 11, and both ends of the limiting sleeve 11 extend to the non-connection points of the fixed connecting rod 7 and the cutting blade fixing rod 8, respectively. In use, the screw 9 of one side of the fixed connecting rod 7 and the cutting blade fixing rod 8 is unlocked, and the limiting sleeve 11 of the other side is unlocked. The cutting blade fixing rod 8 is rotated so that it forms a certain angle with the fixed connecting rod 7, and the cutting blade body 6 is installed on the cutting blade fixing seat to realize the installation of the cutting blade body 6. After the cutting blade is fixed, the cutting blade fixing rod 8 is rotated so that the connection end of the cutting blade fixing rod 8 and the fixed connecting rod 7 are aligned and locked with the screw 9, and the installation is completed.
[0019] It should be noted that there can be two limiting sleeves 11. The inner hole of the limiting sleeve 11 matches the outer diameter of the fixed connecting rod 7 and the cutting blade fixing rod 8. The limiting sleeve 11 prevents the screw 9 from falling off due to vibration.
[0020] The above description is only a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present invention should be included within the scope of protection set forth in the claims.
