The flip angle adjustment mechanism 2 includes a rotating wheel 201, and a circle of trapezoidal protrusions is arranged on the outer side of the rotating wheel 201, which is conducive to manually rotating the rotating wheel 201. A transmission shaft 202 is fixedly connected to the middle of the rotating wheel 201, and the transmission shaft 202 is rotatably connected to the protective shell 101. 02 is rotatably connected to two supports on the outside, the bottom of the support is fixedly connected to the rotating rod 102, the outer side of the transmission shaft 202 is rotatably connected to a circular sliding sleeve 204, the end of the sliding sleeve 204 is fixedly connected to the protective shell 101, one end of the sliding sleeve 204 is fixedly connected to a compression spring 203, the other end of the compression spring 203 is fixedly connected to a limited side tooth 205, one side of the limited side tooth 205 is fixedly connected to a side tooth, the outer side of the limited side tooth 205 is fixedly connected to four rectangular limit blocks 206, the sliding sleeve Four rectangular slots are provided inside the sleeve 204, and the rectangular limit block 206 is slidably connected in the slots provided inside the sleeve 204. The upper side of the limit side tooth 205 is connected to the side gear 207 through the side teeth meshing. The side gear 207 is provided with side teeth on one side. When there is no external force, the compression spring 203 pushes the limit side tooth 205 and the side gear 207 to mesh with each other through the side teeth on the opposite side, so that the limit side tooth 205 limits the rotation of the side gear 207, further limiting the rotation of the side gear 207.

The end of the limiting rotating block 211 is triangular, which is convenient for the limiting rotating block 211 to enter the notch opened in the rotating sleeve 208. When the rotating wheel 201 moves downward, the limiting rotating block 211 can enter the notch opened in the rotating sleeve 208 through the transmission shaft 202. At the same time, the transmission shaft 202 can drive the side gear 207 to rotate through the rotating block 211 and the rotating sleeve 208.

[0021] like Figure 1 , Figure 2 , Figure 6 As shown, a rotation adjustment mechanism 3 for adjusting the rotation angle of the rotating rod is provided at the lower end of the transmission shaft 202, and the rotation adjustment mechanism 3 includes a side gear 2 301, and a side tooth is provided on one side of the side gear 2 301.

The other end of the connecting column 403 is fixedly connected to the limiting turntable 402, and the outer side of the limiting turntable 402 is connected to the fixed block 1 for limiting rotation. The pull rod 401 is pushed inward, and the wedge block 404 on the upper side of the pull rod 401 squeezes the wedge block 404 on the lower side of the limiting sliding plate 405 upward, so that the limiting sliding plate 405 drives the limiting side tooth three 406 to move upward, and the limiting side tooth three 406 is connected to the side tooth gear three 304 through side tooth meshing. The side tooth gear three 304 is limited to prevent the rotating rod 102 from being rotated by other external forces.

[0023] like Figure 1 , Figure 2 As shown, a rectangular groove is opened at the upper end of the fixed block 1, and the limiting sliding plate 405 is slidably connected in the rectangular groove opened at the upper end of the fixed block 1. The rectangular groove opened at the upper end of the fixed block 1 limits the rotation of the limiting sliding plate 405. A groove is opened at the bottom of the rectangular groove opened at the fixed block 1, and the pull rod 401 is slidably connected in the groove opened at the fixed block 1.

[0024] like Figure 2 , Figure 8 As shown, a cavity is opened inside the rotating rod 102, and a transmission mechanism 6 for changing the transmission direction is arranged in the cavity opened inside the rotating rod 102. The transmission mechanism 6 includes a rotating gear 601, and the rotating gear 601 is meshed and connected with the side gear 207. A rotating shaft is fixedly connected inside the rotating gear 601, and a short rod screw 602 is fixedly connected to the outer side of the upper end of the rotating shaft. Both ends of the rotating shaft are rotatably connected to the rotating rod 102. The flip angle adjustment mechanism controls the inclination angle of the rotating plate 103 through the side gear 207 and the rotating gear 601.

[0025] The short rod screw 602 is threadedly connected to the long rod screw 603 on the side, and the outer side of the long rod screw 603 is fixedly connected to a limiting block. A sliding groove is opened in the internal cavity of the rotating rod 102, and the limiting block is slidingly connected in the sliding groove opened in the rotating rod 102. The end of the long rod screw 603 is fixedly connected to a rotating column 604.

[0026] A rotating plate 103 is hinged at the end of the rotating rod 102, and three sliding grooves are opened at the bottom of the rotating plate 103. The rotating column 604 is slidably connected in the sliding groove opened at the bottom of the rotating plate 103. The rotating column 604 is rotatably connected to the limiting slider 605 on both sides, and the limiting slider 605 is limitedly slidably connected in the sliding groove opened at the bottom of the rotating plate 103.

[0027] like Fig. 9 , Fig.10 As shown, a locking mechanism 5 for clamping the milling cutter 7 is provided at the upper end of the rotating plate 103, and the locking mechanism 5 includes a threaded sleeve 501. The bottom of the threaded sleeve 501 is fixedly connected to the rotating plate 103, and four through holes are opened on the outer side of the threaded sleeve 501. A clamping slider 503 is slidingly connected in a limited position in the through holes opened on the outer side of the threaded sleeve 501. The outer side of the clamping slider 503 is an inclined surface, and a nut 502 is threadedly connected to the outer side of the upper end of the threaded sleeve 501. The clamping degree of the clamping slider 503 on the milling cutter 7 can be controlled by rotating the threaded sleeve 501, and the milling cutter 7 is arranged inside the threaded sleeve 501.

During disassembly, rotate the nut 502 counterclockwise, the nut 502 moves upward along the threaded sleeve 501, so that the clamping slider 503 relaxes the squeezing of the milling cutter 7. When it is completely relaxed, pull out the milling cutter 7.

[0029] When adjusting the angle, the pull rod 401 is pulled outward, so that the upper wedge block 404 is staggered with the lower wedge block 404 of the limit sliding plate 405, and the limit side tooth three 406 and the limit sliding plate 405 slide downward by their own gravity, so that the limit side tooth three 406 is disengaged from the teeth on the side opposite to the side gear three 304. At this time, the compression spring 203 pushes the limit side tooth one 205 upward, so that the limit side tooth one 205 is meshed with the side teeth on the side opposite to the side gear one 207, and the limit side tooth one 205 moves upward and pushes the transmission shaft 202 upward through the limit ring two 212, so that the limit rotating block 211 is disengaged from the rotating sleeve one 208. At the same time, the transmission shaft 202 moves upward to drive the limit side tooth two 303 to move upward, and the limit side tooth two 303 at the lower end of the transmission shaft 202 is meshed with the side teeth on the side opposite to the side gear two 301, and rotates counterclockwise. The rotating wheel 201 rotates counterclockwise with the transmission shaft 202, and the transmission shaft 202 simultaneously drives the limit rotating blocks 211 and the limit side gear 2 303 at both ends to rotate counterclockwise, and the transmission shaft 202 drives the limit rotating block 211 to rotate counterclockwise, and the transmission shaft 202 drives the side gear 2 301 to rotate counterclockwise through the limit side gear 2 303, and the side gear 2 301 drives the side gear 3 304 to rotate clockwise through the outer teeth, and the side gear 3 304 rotates and drives the connecting column 403 to rotate clockwise, and the connecting column 403 rotates clockwise to drive the limit rotating disk 402 to rotate clockwise, and the connecting column 403 and the limit rotating disk 402 rotate clockwise to drive the rotating rod 102 to rotate clockwise, and the rotating wheel 201 stops rotating when it rotates to a suitable position, and the angle of the rotating rod 102 is adjusted so that the milling cutter 7 can have a suitable working angle through the rotating rod 102.

The rotating wheel 201 is rotated counterclockwise, and the rotating wheel 201 drives the transmission shaft 202 to rotate counterclockwise. The transmission shaft 202 simultaneously drives the limiting rotating blocks 211 at both ends to engage with the limiting side tooth 2 303 counterclockwise. The needle rotates, and the transmission shaft 202 drives the limited side gear 2 303 to rotate counterclockwise.
