[0051] It should be noted here that: by cutting the cutting groove 2 on the support bar, the protrusion 3 is formed, so that the shape of the protrusion 3 can match the shape of the notch on the aramid paper, which facilitates the limiting effect when the support bar and the aramid paper are assembled.

[0052] The support bar body 1 is arranged in a strip-shaped structure.

[0053] The protrusion 3 is arranged in a triangular structure.

The rear end of the support body 1 passes through the mounting hole 7 and rests against the rear end of the positioning plate 8.

[0056] It should be noted here that: when the support bar is inserted into the mounting hole 7, the saw blade 5 can cut a cutting groove 2 on the support bar during the process of rotating the mounting plate 6 downward. By cutting a cutting groove 2 on both sides of the support bar, a triangular protrusion 3 is formed on the support bar body 1. The protrusion 3 matches the notch on the aramid paper, which facilitates the limiting effect when the support bar and the aramid paper are assembled. By setting the positioning plate 8, the support bar can be positioned during the cutting process, and a number of connecting holes 9 are opened on the positioning plate 8. The connecting holes 9 are used to adjust the installation position of the positioning plate 8 and the mounting plate 6, thereby adjusting the position of the cutting groove 2 on the support bar.

[0057] The saw blade 5 is arranged in a circular structure. Due to the shape of the saw blade 5, the two side walls of the cutting groove 2 on the support are inclined from the outside of the support body 1 toward the center. Therefore, after the grooves are cut on both sides of the support, a triangular protrusion 3 is formed at the connection of the side walls of the cutting groove 2. The protrusion 3 matches the notch on the aramid paper, which plays a limiting role when the support and the aramid paper are assembled.

A through slot 12 is opened on the baffle 11 to ensure that the saw blade 5 can pass through the through slot 12 and cut on the support bar.

[0061] The positioning plate 8 includes a first plate 13 and a second plate 14 connected vertically. Several connecting holes 9 are opened on the first plate 13. The second plate 14 is located behind the mounting hole 7. The rear end of the support body 1 passes through the mounting hole 7 and abuts against the second plate 14.

[0062] It should be noted here that: the first plate 13 is used to connect with the mounting plate 6, and the installation position of the positioning plate 8 and the mounting plate 6 is adjusted by the position of several connecting holes 9 on the first plate 13, and then the distance between the second plate 14 and the rear end of the mounting plate 6 is adjusted. The second plate 14 is arranged behind the mounting hole 7, so the rear end of the support bar passes through the mounting hole 7 and rests on the second plate 14.

[0078] It also includes: a gantry 29, which is mounted on the frame 4, and a lifting hoist 30 is provided on the gantry 29. A handle 31 is provided on the end of the mounting plate 6 that is not connected to the adjustment device, and the handle 31 is connected to the lifting hoist 30 through a spring 32.

[0079] It should be noted here that since the mounting plate 6 and the positioning plate 8 are heavy, the mounting plate 6 can be pulled up by the cooperation of the lifting hoist 30 and the spring 32 on the gantry 29, saving manpower.

[0080] The specific operating principle of the utility model is as follows:

[0081] Adjust the position of the positioning plate 8 according to the cutting position of the cutting groove 2, adjust the distance between the second plate 14 and the rear end of the mounting plate 6, and then lock the first plate 13 on the mounting plate 6 by screws; the lifting hoist 30 pulls the spring 32 to rise, as shown in FIG.
