[0002] Chain saws, also known as oil saws, are portable saws powered by gasoline engines. They are mainly used for logging and timber making. Their working principle is to cut by the lateral movement of the staggered L-shaped blades on the saw chain. Chain saws are generally divided into motorized chain saws and non-motorized chain saws. The teeth of the chain saw will become blunt due to wear after long-term use, affecting the cutting efficiency and quality. Therefore, it is necessary to use a grinding device to regularly grind the saw blade of the chain saw to maintain its sharpness.
[0003] When grinding a chain saw, it is usually necessary to use a special round file or chain saw file and follow specific techniques and steps, such as ensuring the correct filing angle, moderate feed speed, and filing along the shape and direction of the saw teeth to avoid damaging the saw teeth or the file itself. During the grinding process, the file can only grind one side of the saw teeth in one back and forth. To improve the grinding efficiency, the operator will use a V-shaped grinding seat to grind the saw teeth, but because the grinding seat will wear out after long-term use, when it continues to be used, the saw blade will not fit with the grinding seat, affecting the saw blade grinding effect and poor applicability.

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0023] according to Figure 1 , 2 As shown in , 3 and 4, a saw chain blade edge grinding device is proposed in this embodiment, including a first blade holder 1 and a second blade holder 2, the first blade holder 1 and the second blade holder 2 are matched with each other, and the first blade holder 1 and the second blade holder 2 are detachably connected;
[0024] A clamp block 3 is provided at the upper end of the first tool holder 1 and the upper end of the second tool holder 2. The two clamp blocks 3 are fixedly connected to the first tool holder 1 and the second tool holder 2 respectively. An inclined groove 4 is provided on the side of the two clamp blocks 3 close to each other. A grinding block 5 is provided in the inclined groove 4. The two grinding blocks 5 are V-shaped together. The saw chain blade is placed between the two clamp blocks 3, and the grinding block 5 in the clamp blocks 3 grinds the cutting edge of the blade.
[0025] An adjusting mechanism for changing the distance between the two grinding blocks 5 is provided on the side of the clamp block 3 away from the inclined groove 4, and the adjusting mechanism is detachably connected to the grinding block 5. The distance between the two grinding blocks 5 is adjustable, and the grinding block 5 can always be kept in contact with the saw chain blade through the adjusting mechanism, which can be applied to blades of different thicknesses and has a wide range of applicability.
[0026] About the regulatory agencies:
[0027] The adjusting mechanism comprises an adjusting bolt 6 , which is mounted on a side of the clamp block 3 away from the inclined slot 4 , passes through the clamp block 3 and is detachably connected to the grinding block 5 , and is threadedly connected to the clamp block 3 .
[0028] comprehensive Figure 1 , the use of the regulating mechanism is;
[0029] When the distance between the two grinding blocks 5 increases due to long-term use, the adjusting bolt 6 can be rotated and screwed into the inclined groove 4, so that the two grinding blocks 5 are moved closer to each other, so that the grinding blocks 5 always keep in contact with the saw chain blade.
[0030] The detachable connection between the first knife seat 1 and the second knife seat 2 is described below.
[0031] A slot 15 is provided on the side of the first knife seat 1 close to the second knife seat 2, and a positioning protrusion 16 is provided on the side of the second knife seat 2 close to the first knife seat 1. The positioning protrusion 16 is plugged into the slot 15. Second bolt seats 12 are provided on both sides of the first knife seat 1, and third bolt seats 13 are provided on both sides of the second knife seat 2. The second bolt seat 12 and the third bolt seat 13 are matched with each other, and the second bolt seat 12 and the third bolt seat 13 are equipped with fixing bolts 14 for fixing the second bolt seat 12 and the third bolt seat 13.
[0032] When the first tool holder 1 and the second tool holder 2 are combined together, the positioning protrusion 16 on the second tool holder 2 will be inserted into the slot 15 provided on the first tool holder 1. The positioning protrusion 16 cooperates with the slot 15 to increase the fit between the first tool holder 1 and the second tool holder 2. After releasing the lock between the second bolt seat 12 and the third bolt seat 13, the first tool holder 1 and the second tool holder 2 can be removed separately. The advantage of the split type is that it is convenient for the staff to maintain and replace the clamp block 3 and the grinding block 5.
[0033] In a preferred embodiment, the grinding block 5 includes a grinding head 51 and a mounting sleeve 52, the grinding head 51 is fixedly connected to one side of the mounting sleeve 52, the other side of the mounting sleeve 52 is sleeved on the outside of the adjusting bolt 6, and the inner wall of the mounting sleeve 52 is threadedly connected to the outer wall of the adjusting bolt 6. The grinding block 5 is fixed to the adjusting bolt 6 by a threaded connection, so that when the grinding block 5 cannot be used anymore due to wear and the entire grinding device needs to be replaced, it is only necessary to unscrew the mounting sleeve 52 on the grinding head 51 from the outside of the adjusting bolt 6, and the grinding block 5 can be replaced alone.
[0034] It is worth further explaining that the lower ends of the first tool holder 1 and the second tool holder 2 are both provided with a first bolt seat 9, which is fixedly connected to the side of the first tool holder 1 and the second tool holder 2 that are away from each other, and a bolt hole 11 is provided on the first bolt seat 9. The first tool holder 1 and the second tool holder 2 can be fixed on the stand by bolt connection, so that the entire device will not shake during grinding.
[0035] In a better embodiment, a reinforcing rib 8 is provided at the connection between the clamp block 3 and the first tool holder 1. The reinforcing rib 8 is fixedly connected to the side of the clamp block 3 away from the inclined groove 4, and the lower end of the reinforcing rib 8 is fixedly connected to the upper end of the first tool holder 1. The saw chain blade is placed between the two grinding blocks 5 for grinding. During the grinding process, the saw chain blade will apply pressure to the clamp block 3 through the grinding blocks 5 and the adjustment bolt 6. The reinforcing rib 8 is provided at the connection between the clamp block 3 and the first tool holder 1, which can effectively strengthen the structural strength of the connection between the clamp block 3 and the first tool holder 1 and improve the impact resistance of the grinding device.
[0036] In another preferred embodiment, a drainage groove 7 is provided on the side of the jaw block 3 away from the chute 4, the drainage groove 7 is placed below the adjustment bolt 6, and the drainage groove 7 is connected to the chute 4. In order to enhance the grinding effect, grinding fluid is dripped between the two jaw blocks 3 during grinding, and the drainage groove 7 provided on the outside of the jaw block 3 can discharge the waste liquid falling on the bottom of the chute 4 to the outside, thereby preventing the waste liquid from accumulating in the chute 4 and causing the first tool holder 1 and the jaw block 3 to rust.
[0037] How this application works:
[0038] The saw chain blade is placed between the two clamps 3, and the grinding block 5 in the clamps 3 grinds the blade edge. When the grinding block 5 is used for a long time, the distance between the two grinding blocks 5 increases, the adjustment bolt 6 can be rotated and screwed into the inclined groove 4, and the two grinding blocks 5 are brought closer to each other, so that the grinding block 5 always keeps in contact with the saw chain blade. At the same time, it can also be applied to blades of different thicknesses, and has a wide range of applicability.
