[0022] The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the drawings. Embodiment

[0023] As Figure 1 , Figure 2 and Figure 3 shown, a long-life buffer saw chain guide plate for lightweight brick cutting includes: a guide plate head and a plate body; the plate body includes two outer guide plates 1 on both sides and an inner guide plate 2 sandwiched inside; a guide plate head insertion hole is opened along the horizontal central axis on the front side of the plate body, wherein the axial length of the guide plate head insertion hole of the inner guide plate is greater than that of the outer guide plate.

[0024] A spring buffer device 6 is installed in the guide head insertion hole of the inner guide plate, and the upper and lower surfaces of the spring buffer device are covered and wrapped by the outer guide plate;

[0025] The spring buffer device cooperates with the guide head to work.

[0026] The guide head includes: outer guide head plates 3 on both sides, inner guide head plates 4 sandwiched inside, and guide head circular plates 5 on both sides;

[0027] Among them, a limiting groove is opened on the long side of the inner guide head plate, and a flange 2-1 integrally cut and formed is arranged on the inner guide plate, and the flange cooperates with this limiting groove; the length of the flange is less than the active length of the limiting groove.

[0028] The length difference between the flange and the limiting groove is the maximum buffer length set for the spring buffer device.

[0029] As Figure 5 shown, on the inner side of the outer guide plate corresponding to the area where the spring buffer device is located in the inner guide plate, an arc groove is arranged along the horizontal central axis, and the number and position of the arc grooves match the springs of the spring buffer device.

[0030] The first end 6-1 of the spring buffer device is fixed inside the plate body, and the second end 6-2 slides in the guide head insertion hole; wherein the height of the second end is less than the width of the guide head insertion hole (as Figure 1 shown), and the short side is a rectangular short side with an arc or rounded corner transition.
