When in use, the height of the support is adjusted by the lifting structure, and a slide rail 71 is installed on the bottom plate 7, and a slider 72 is installed on the lower side of the slide plate 1, and the slider 72 is connected to the slide rail in a sliding manner. When the boss on the mounting position 30 of the milling machine head 10 is in an oblique state, as long as the boss is aligned with the notches on both sides of the cutter head, when the support rises or falls, the support can adjust the left and right positions along the slide rail, thereby facilitating the installation and disassembly of the cutter head.

[0028] In a preferred embodiment, see Figure 1-4 The lifting structure includes two first hinge seats 11 and two first sliding seats 12 arranged at both ends of the upper side of the slide plate 1, two second hinge seats 21 and two second sliding seats 22 arranged at both ends of the lower side of the support plate 2, and cross connecting rods respectively located on both sides between the slide plate 1 and the support plate 2, the first sliding seat 12 is provided with a first transverse long hole 13, the second sliding seat 22 is provided with a second transverse long hole 23, the cross connecting rod includes a first connecting rod 3 and a second connecting rod 4, one end of the first connecting rod 3 is hinged to the second hinge seat 21 through a first pivot 31, and the other end is hinged to the first sliding shaft 3 2, both ends of the first sliding shaft 32 penetrate into the first transverse long hole 13, one end of the second connecting rod 4 is hinged to the first hinge seat 11 through the second pivot 41, and the other end is connected to the second sliding shaft 42, both ends of the second sliding shaft 42 penetrate into the second transverse long hole 23, and the middle parts of the first connecting rod 3 and the second connecting rod 4 are rotatably connected through the third pivot 5; the support plate 2 is provided with a fixing plate 24 at the lower side of one end of the second sliding seat 22, the screw rod 25 is transversely threadedly connected to the fixing plate 24, one end of the screw rod 25 is connected to the second sliding shaft 42 for rotation and limitation, and the other end extends outward from the fixing plate 24. When in use, by rotating the screw rod 25, the screw rod 25 pushes inward or pulls outward the second sliding shaft 42, so that the support plate 2 moves up and down, thereby driving the cutter head 20 placed on the support to move up and down.

[0029] In a preferred embodiment, see Figure 4 The second slide shaft 42 is provided with a bolt hole, and the screw 27 is inserted into the bolt hole and screwed and fixed with the screw rod 25. At this time, the screw 27 does not move relative to the screw rod 25, and the screw 27 can only rotate with the screw rod 25. The distance between the large end of the screw 27 and the screw rod 25 is greater than the thickness or diameter of the second slide shaft 42. Through the above structure, the screw rod 25 is connected with the second slide shaft 42 in a rotationally limited manner.

[0030] In another embodiment, the screw rod 25 is provided with a small head end, which moves through the second sliding shaft 42, and then a gasket and a cotter pin are installed at one end of the small head end extending out of the second sliding shaft 42, so that the screw rod 25 and the second sliding shaft 42 can be rotationally limitedly connected.

[0031] Further, one end of the screw rod 25 extending outward from the fixing plate 24 is provided with a handle 26 for facilitating the rotation of the screw rod 25. The handle 26 may be a hand wheel mounted on the screw rod 25, or a section of round steel welded to the end of the screw rod 25.

[0032] See also Figure 1 Baffles 73 are provided on the bottom plate 7 at both ends of the slide rail 71 to prevent the slider 72 from sliding out of the slide rail 71. Specifically, the baffles 73 are welded on the bottom plate 7.

[0033] The use process or principle of the utility model is as follows:

[0034] When installing the blade disc 20 , first place the blade disc 20 on the placement slot 61 of the device, with the main body of the blade located in the accommodation space 62 .

[0035] See also Figure 5 When the boss on the mounting position 30 is in a longitudinal state, the device is moved to the position directly below the milling machine head 10 so that the notch on the blade corresponds to the boss, and the handle 26 is turned to drive the support to rise, thereby driving the cutter disc 20 placed on the support to move upward until the cutter disc 20 is installed in place.

[0036] See also Figure 6 When the boss on the mounting position 30 is in an oblique state, the boss is aligned with the notches on both sides of the cutter disc, the handle 26 is turned, the support rises, and at the same time the support is pushed to move to the left along the slide rail, so that the cutter disc moves obliquely upward until the cutter disc 20 is installed in place.

[0037] When the cutter disc 20 is disassembled, when the boss on the mounting position 30 is in a longitudinal state, the support is raised to receive the cutter disc 20, and after receiving the cutter disc 20, the support is lowered.

[0038] Since the boss on the mounting position 30 is not easy to locate, that is, the boss on the mounting position 30 is in a longitudinal state, which is an ideal state, but in most cases it is inclined. Figure 6 In the embodiment, the angle of the boss on the mounting position 30 is controlled within the range of 90° as shown in the figure. At this time, when the cutter disc 20 is disassembled, the support is raised to receive the cutter disc 20, and after receiving it, the support is lowered, and the support slides to the right at the same time, thereby disassembling the cutter disc.
