[0002] In many fields such as forestry, timber processing, construction, and horticulture, chainsaws are an indispensable tool that can efficiently cut materials such as wood. The chain guide is a key component in chainsaws and other cutting equipment. It mainly provides support and guidance for the chain. During high-speed operation, the chain needs to run along a specific track, and the chain guide is like this track, ensuring that the chain can make precise cutting movements.
[0003] In terms of guide plate installation and replacement, multiple bolts and nuts are usually required to fasten the guide plate. When the guide plate needs to be replaced, the operator must loosen and remove these bolts and nuts one by one before the guide plate can be disassembled. After installing the new guide plate, the bolts and nuts must be tightened again, resulting in low guide plate replacement efficiency. To solve the above problems, a quick-replacement saw chain guide plate fixing device is proposed. Summary of the Invention

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a quick-replaceable saw chain guide fixing device, including a housing 1, which is the main body of the electric saw and can drive the sprocket 7 to rotate. A mounting cover 3 is provided on the left side of the housing 1, which is installed by bolts and works in conjunction with the housing 1. It is mainly used to close one side of the device and also provides installation positions for the adjusting component 44 and the limiting component. A guide plate 2 is provided on the inner side of the housing 1 and is a supporting and guiding component for the saw chain 6. This technology is prior art and will not be described in detail. The sprocket 7 is provided on the left side of the housing 1, and its main function is to drive the saw chain. The saw chain 6 is installed on the outer side of the guide plate 2. It is a component for sawing and can cut wood or other materials. The saw chain 6 is located on the outer side of the sprocket 7 at the rear. The inner walls of the housing 1 and the mounting cover 3 are provided with an adjustment mechanism. The adjustment mechanism includes an adjustment component and an auxiliary component. The adjustment component includes a sliding component 42, which connects the housing 1 and the guide plate 2. At the same time, during the adjustment process, the guide plate 2 can move smoothly within a certain range according to the movement of the adjustment component 44 to fasten the saw chain 6. Its sliding connection method ensures the flexibility of the guide plate 2 position adjustment.
[0026] Furthermore, the sliding member 42 is slidably connected to the inner wall of the housing 1, and the left side of the sliding member 42 slides through the rear inner wall of the guide plate 2. An adjusting member 44 is slidably connected to the inner wall of the mounting cover 3. When the adjusting member 44 moves, it can drive the guide plate 2 to move through the insertion relationship between the adjusting member 42 and the insert hole 43. At the same time, the U-shaped design of the adjusting member 44 can increase the connection points with the guide plate 2, so that the adjusting force is more evenly distributed on the guide plate 2, thereby adjusting the position of the guide plate 2 more accurately. The adjusting member 44 has an insertion hole 43 on its right side, through which the adjusting member 44 is inserted into the sliding member 42. When the guide plate 2 needs to be replaced, the adjusting member 44 is removed, so that the adjusting member 44 is disengaged from the sliding member 42, and then the guide plate 2 can be removed to complete the replacement, thereby improving the replacement efficiency of the guide plate 2. At the same time, through the insertion and movement of the sliding member 42 in the insertion hole 43, the movement of the adjusting member 44 can be transmitted to the guide plate 2, thereby changing the position of the guide plate 2 and achieving the purpose of quickly and stably adjusting the tension of the saw chain 6.
[0027] Reference Figure 3 - Figure 5 The right side of the adjusting component 44 is attached to the left side of the guide plate 2, and the left side of the sliding component 42 is inserted into the inner wall of the insertion hole 43. A threaded rod 45 is rotatably connected to the inner wall of the mounting cover 3. The outer side of the threaded rod 45 is threadedly connected to the inner wall of the left side of the adjusting component 44. When the threaded rod 45 rotates, the adjusting component 44 can slide on the inner wall of the mounting cover 3 due to the action of the thread. In this way, the displacement of the adjusting component 44 can be precisely controlled, thereby achieving fine adjustment of the position of the guide plate 2. A regular hexagonal groove is opened on the front side of the threaded rod 45 to facilitate rotation operation using tools such as an Allen wrench.
[0028] Reference Figure 2 and Figure 3 The auxiliary components include a positioning block 41, which is fixedly connected to the inner wall of the housing 1. The left side of the positioning block 41 is inserted into the right inner wall of the mounting cover 3, and the rear of the guide plate 2 slides on the outside of the positioning block 41. The positioning block 41 mainly plays the role of positioning and auxiliary support. On the one hand, it can ensure that the mounting cover 3 is accurately positioned and tightly fitted with the housing 1 during installation. On the other hand, it provides a guide and auxiliary support track for the movement of the guide plate 2, so that the guide plate 2 can slide more smoothly during adjustment, improving the adjustment accuracy and the stability of the device. The adjusting part 44 and the sliding part 42 are set in a U-shape, which can increase the connection points and thus improve the stability of the guide plate 2. Two sets of insertion holes 43 are provided, and the two sets of insertion holes 43 are respectively opened at both ends of the U-shape of the insertion hole 43.
[0029] Reference Figure 4 and Figure 6The inner wall of the mounting cover 3 is provided with a limiting component, which includes a limiting member 51. The limiting member 51 is slidably connected to the inner wall of the mounting cover 3. When the limiting member 51 is inserted into the limiting hole 53, it can prevent the threaded rod 45 from rotating unexpectedly due to vibration or other factors during operation, thereby ensuring the stability of the guide plate 2. The upper side of the limiting member 51 is elastically connected to the mounting cover 3 through the limiting hole 53. The limiting hole 53 is initially in a compressed state, providing elastic force to the limiting member 51, so that it can maintain a thrust in the direction of the limiting hole 53 under normal conditions, ensuring that the limiting member 51 can be tightly inserted into the limiting hole 53 and effectively play its limiting role.
[0030] Furthermore, a limiting hole 53 is provided at the front of the threaded rod 45 to provide an insertion position for the limiting member 51. The limiting member 51 is inserted into the inner wall of the limiting hole 53. Multiple sets of limiting members 51, compression springs 52 and limiting holes 53 are provided. These multiple sets of limiting members 51, compression springs 52 and limiting holes 53 are arranged in a circumferential array with the center point of the threaded rod 45 as the axis, which can limit the threaded rod 45 from multiple directions and enhance the reliability of the limiting. The side of the limiting member 51 near the limiting hole 53 is set as an arc surface, which facilitates the alignment and insertion of the limiting member 51 with the limiting hole 53 during installation or disassembly.
[0031] Working principle: When the guide plate 2 needs to be replaced, rotate the threaded rod 45 in the opposite direction to move the adjusting part 44 to the rear, which drives the sliding part 42 to move synchronously and release the fastening of the guide plate 2. At this time, the mounting cover 3 can be removed from the housing 1, which will cause the adjusting part 44 to separate from the sliding part 42, allowing the sliding part 42 to slide out of the insertion hole 43, thereby releasing the fixation of the guide plate 2, and the guide plate 2 that needs to be replaced can be disassembled.
[0032] When installing the new guide plate, first insert the new guide plate onto the outside of the slider 42, aligning its rear with the positioning block 41. Then, align the adjusting piece 44 with the slider 42 and insert it through the insertion hole 43.
[0033] At this time, rotating the threaded rod 45 overcomes the elastic force of the compression spring 52, causing the adjusting part 44 to slide on the inner wall of the mounting cover 3, so that the adjusting part 44 drives the sliding part 42 to move synchronously, thereby driving the guide plate 2 to move, fixing the guide plate 2 in a suitable position, and tightening the saw chain 6.
[0034] During the operation of the device, multiple sets of limiting components 51, under the action of compression springs 52, drive the limiting components 51 to insert into the limiting holes 53, which can effectively prevent the threaded rod 45 from rotating unexpectedly, thereby ensuring the stability of the guide plate 2, ensuring that the saw chain 6 always works stably under appropriate tension, improving the sawing accuracy and efficiency, and ensuring the stable operation of the entire device.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
