DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Embodiment 1:

[0025] An easily adjustable chain saw guide bar, such as Figure 1-4 As shown, it includes a chip removing component, which includes a second guide plate 12, a guide rail 3 is provided on one side of the second guide plate 12, a slot is provided on one side of the second guide plate 12, an air pump 6 is installed through the slot, and an air suction port 4 is connected to one side of the air pump 6, an air outlet frame 18 is embedded and fixed on one side of the second guide plate 12, and two groups of air outlet frames 18 are provided, which are respectively installed on the upper and lower sides of the second guide plate 12, the air outlet frames 18 are adapted to the guide rail 3, and the air outlet frames 18 are connected to the air pump 6, a mounting frame 9 is fixedly provided on the outer wall of one side of the second guide plate 12 by welding, and the mounting frame 9 is provided with multiple groups of screw holes, and an adjustment component for adjusting the tightness of the saw blade and a tension adjustment component for adjusting the tension of the saw blade are provided on one side of the second guide plate 12.

[0026] When in use, the installation is completed by aligning the screw hole of the mounting frame 9 with the bolt at the chain saw mounting position, inserting the bolt and tightening the nut, and the saw blade is installed through the guide rail 3. When the saw blade is rotated for cutting, the air pump 6 is started, and the air suction port 4 sucks air, and the sucked air is discharged through two groups of air outlet frames 18. The air outlet frame 18 is evenly provided with multiple groups of air outlets. The air discharged through the air outlet can clean the saw blade during cutting and blow away the debris attached to it, thereby avoiding the accumulation of debris in the guide rail 3 causing the saw blade to get stuck, and at the same time, it can avoid the accumulation of debris that accelerates the wear of the saw blade.

[0027] The adjustment assembly includes a first guide plate 1, which is arranged on one side of the second guide plate 12. An adjustment frame 13 is arranged on one side of the second guide plate 12. The adjustment frame 13 is provided with two groups. The adjustment frame 13 is sequentially provided with multiple groups of fixing holes 14. A connecting groove 16 is arranged on one side of the first guide plate 1, and the connecting groove 16 is adapted to the adjusting frame 13. A limiting hole 17 is arranged on one side of the first guide plate 1, and the limiting hole 17 is adapted to the connecting groove 16.

[0028] When in use, the connection between the first guide plate 1 and the second guide plate 12 is completed by inserting the connecting groove 16 into the adjusting frame 13. The first guide plate 1 is also provided with a guide rail 3 to facilitate the rotation of the saw blade. When the tightness of the saw blade needs to be adjusted, the first guide plate 1 can be controlled to move horizontally, and the saw blade can be adjusted to a suitable tightness by moving the first guide plate 1 to the adjusting frame 13. After the adjustment is completed, the fixing pin 2 is installed through the limiting hole 17 to fix it. The position is restricted by aligning the fixing hole 14 with the limiting hole 17 and inserting the fixing pin 2 to avoid the sliding displacement of the first guide plate 1 affecting the tightness of the saw blade.

[0029] The tension adjustment assembly includes a support frame 19, an electric telescopic rod 11 is arranged at the bottom of the support frame 19, a groove is arranged on one side of the second guide plate 12, the electric telescopic rod 11 is embedded and installed in the groove of the second guide plate 12, and one end of the support frame 19 is designed in an arc shape and is adapted to the groove of the second guide plate 12.

[0030] When in use, the electric telescopic rod 11 can drive the support frame 19 to extend or retract. When not in use, it can be retracted into the groove of the second guide plate 12 to prevent affecting the rotation of the saw blade. When adjusting the tension of the saw blade, the electric telescopic rod 11 can drive the support frame 19 to extend and support one end of the saw blade, so that the saw blade maintains an appropriate tension. The support frame 19 is provided with a slot, through which the saw blade can rotate normally, avoiding the saw blade from getting stuck when adjusting the tension.

[0031] To prevent inhalation of foreign matter, such as Figure 1 As shown, a filter screen 5 is detachably mounted on one side of the air inlet 4 .

[0032] When in use, the filter screen 5 can filter air when the air inlet 4 is sucking in air, so as to avoid foreign matter or flying debris being sucked into the device and causing it to get stuck, thereby reducing unnecessary maintenance costs.

[0033] To make the installation more secure, Figure 2 As shown, a gasket 8 is provided on one side of the mounting frame 9, and two groups of gaskets 8 are provided, which are respectively installed on both sides of the mounting frame 9.

[0034] When in use, the gasket 8 is made of rubber material, and the gasket 8 is provided with an opening corresponding to the screw hole of the mounting frame 9. When fixing the device, the rubber gasket 8 can make the mounting frame 9 more securely fixed, prevent the formation of gaps at the fixing place, and at the same time, can provide shock absorption and buffering for the guide plate during operation.

[0035] To add lubricating oil, Figure 3 As shown, a refueling port 7 is provided on one side of the second guide plate 12 , and two groups of refueling ports 7 are provided, which are respectively arranged on the upper and lower sides of the second guide plate 12 .

[0036] When in use, the position of the oil filling port 7 is matched with the guide rail 3. Pouring lubricating oil into the oil filling port 7 allows the lubricating oil to enter the guide rail 3, and lubricates the saw blade and the guide rail 3 in coordination with the rotation of the saw blade, thereby avoiding the situation where the saw blade is too dry and causes accelerated wear.

[0037] In order to facilitate the addition of lubricating oil, Figure 2 , 3 As shown, a funnel 10 is detachably mounted on one side of the fuel filling port 7 .

[0038] During use, when adding lubricating oil through the refueling port 7, the refueling port 7 is small and inconvenient for adding lubricating oil, and it is easy to be tilted and cause waste of lubricating oil. A funnel 10 is installed through the refueling port 7, and the lubricating oil is poured into the funnel 10. The funnel 10 sends the lubricating oil to the guide rail 3 to lubricate the saw blade, which can effectively avoid waste of lubricating oil. Embodiment 2:

[0039] To facilitate adjustment, refer to Figure 3 , an easily adjustable chain saw guide plate, this embodiment makes the following improvements compared to embodiment 1: a pull ring 15 is provided on one side of the first guide plate 1.

[0040] When in use, the pull ring 15 is provided to facilitate the use of hands or tools to exert force to move the first guide plate 1 when adjusting the tightness of the saw blade, thereby avoiding directly pinching the smooth first guide plate 1 which is inconvenient to exert force to control its movement, and preventing the hand from slipping on the smooth first guide plate 1 and being scratched by the saw blade.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
