The upper side of the limit side tooth 1 205 is connected to the side tooth gear 1 207 through the side teeth meshing. The side of the side tooth gear 1 207 is provided with side teeth. When there is no external force, the compression spring 203 pushes the limit side tooth 1 205 and the side tooth gear 1 207 to mesh with each other through the side teeth on the opposite sides, so that the limit side tooth 1 205 limits the rotation of the side tooth gear 1 207, further limiting the rotation of the side tooth gear 1 The braking plate 103 rotates, and a limiting ring 212 is provided between the limiting side tooth 1 205 and the side tooth gear 1 207. The limiting ring 212 is fixedly connected to the transmission shaft 202, and can push the rotating wheel 201 downward to drive the transmission shaft 202 to move downward.

The limiting side tooth 1 205 moves downward and disengages from the side tooth gear 1 207, and compresses the compression spring 203, so that the side tooth gear 1 207 loses its restriction.

[0032] like Figure 3 、 Figure 4 、 Figure 5As shown, the side gear 1 207 is internally fixedly connected to the rotating sleeve 1 208, the rotating sleeve 1 208 is rotatably connected to the transmission shaft 202, the outer side of the rotating sleeve 1 208 is rotatably connected to the support block 209, the support block 209 is fixedly connected to the protective shell 101, and the upper and lower sides of the support block 209 are rotatably connected to the limiting ring 1 210, the limiting ring 1 210 is fixedly connected to the rotating sleeve 1 208, and the limiting ring 1 210 limits the side gear 1 207 from moving up and down through the rotating sleeve 1 208, so that the side gear 1 207 always keeps its position unchanged, and the outer portion of the upper end of the transmission shaft 202 There are four limit rotating blocks 211 fixedly connected to the side, and four notches are opened at the end of the rotating sleeve 208.

The end of the limit rotating block 211 is triangular, which is convenient for the limit rotating block 211 to enter the notch opened in the rotating sleeve 208. When the wheel 201 moves downward, the limit 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.

[0033] like Figure 1 、 Figure 2 、 Figure 6 As shown, the lower end of the transmission shaft 202 is provided with a rotation adjustment mechanism 3 for adjusting the rotation angle of the rotating rod, and the rotation adjustment mechanism 3 includes a side tooth gear 2 301, and a side tooth is provided on one side of the side tooth gear 2 301.

The outer side of the side tooth gear 2 301 is connected to the side tooth gear 3 304 through tooth meshing. One side of 304 is fixedly connected with a side tooth. When the compression spring 203 pushes the limiting side tooth 1 205, the limiting side tooth 1 205 can push the transmission shaft 202 upward through the limiting ring 212.

The transmission shaft 202 rotates through the limiting side tooth 2 303 and the side tooth gear 2 301 to drive the side tooth gear 3 304 to rotate, so that the side tooth gear 3 304 drives the rotating rod 102 to rotate through the connecting column 403 and the limiting turntable 402.

[0034] like Figure 1 、 Figure 2 、 Figure 7As shown, a rotation limiting mechanism 4 is provided on the lower side of the side gear 304 to prevent the rotating rod 102 from rotating due to other external forces.

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

[0035] like Figure 1 、 Figure 2 As shown, a rectangular slot is opened at the upper end of the fixed block 1, and the limiting sliding plate 405 is slidably connected in the rectangular slot opened at the upper end of the fixed block 1. The rectangular slot opened at the upper end of the fixed block 1 limits the rotation of the limiting sliding plate 405. A slot is opened at the bottom of the rectangular slot opened at the fixed block 1, and the pull rod 401 is slidably connected in the slot opened at the fixed block 1.

[0036] 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 set 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 tilt angle of the rotating plate 103 through the side gear 207 and the rotating gear 601.

[0037] The short rod screw 602 is threadedly connected to the long rod screw 603 on the side, and the outside of the long rod screw 603 is fixedly connected to a limit block. A sliding groove is opened in the internal cavity of the rotating rod 102, and the limit 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 the rotating column 604.

[0038] The end of the rotating rod 102 is hinged with a rotating plate 103, 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 two sides of the rotating column 604 are rotatably connected to the limiting slider 605, and the limiting slider 605 is slidingly connected in the sliding groove opened at the bottom of the rotating plate 103.

[0039] like Figure 9 、 Figure 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. The clamping slider 503 is slidingly connected 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 the outer side of the upper end of the threaded sleeve 501 is threadedly connected to a nut 502. The degree of clamping 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.

[0040] Working principle: During operation, insert the milling cutter 7 into the bottom of the threaded sleeve 501, rotate the nut 502 clockwise, the nut 502 moves downward along the threaded sleeve 501, and squeezes the inclined surface of the clamping slider 503, so that the clamping slider 503 clamps the milling cutter 7 inward, and rotates the nut 502 until the milling cutter 7 is not loose. When disassembling, 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.

[0041] 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 opposite side of 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 opposite side of 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, driving 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 opposite side of the side gear two 301, rotating 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 to drive the connecting column 403 to rotate clockwise, and the connecting column 403 rotates clockwise to drive the limit turntable 402 to rotate clockwise, and the connecting column 403 and the limit turntable 402 rotate clockwise to drive the rotating rod 102 to rotate clockwise. When the rotating wheel 201 is rotated to the appropriate position, the rotating wheel 201 is stopped, 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.

[0042] The upper end of the transmission shaft 202 drives the limit rotating block 211 to move downward, so that the limit rotating block 211 is meshed with the rotating sleeve 1 208. At the same time, the transmission shaft 202 moves downward and drives the limit side tooth 1 205 to move downward through the limit ring 212. The limit side tooth 1 205 moves downward and compresses the compression spring 203, so that the limit side tooth 1 205 is disengaged from the side teeth on the opposite side of the side gear 1 207. The rotating wheel 201 is rotated counterclockwise, and the rotating wheel 201 rotates counterclockwise with the transmission shaft 202. The transmission shaft 202 simultaneously drives the limit rotating blocks 211 at both ends to engage with the limit side tooth 2 303 counterclockwise. The needle rotates, and the transmission shaft 202 drives the limiting side gear 2 303 to rotate counterclockwise. The transmission shaft 202 drives the rotating sleeve 1 208 to rotate counterclockwise through the limiting rotating block 211. The rotating sleeve 1 208 rotates counterclockwise to drive the side tooth gear 1 207 to rotate counterclockwise. The side tooth gear 1 207 rotates counterclockwise through the outer teeth to drive the rotating gear 601 to rotate clockwise. The rotating gear 601 rotates clockwise through the rotating shaft to drive the short rod screw 602 to rotate clockwise. The short rod screw 602 rotates clockwise and drives the long rod screw 603 to move upward through the thread. The long rod screw 603 moves upward and pushes the limiting slider 605 upward through the rotating column 604. The limiting slider 605 moves upward to make the rotating plate 103 rotate clockwise, so that the angle of the rotating plate 103 in the vertical direction is adjusted, and the milling cutter 7 is further adjusted to have a suitable working angle.

[0043] When adjusting the angle of the rotating plate 103 downward, the rotating wheel 201 is dialed downward and rotated clockwise. The rotating wheel 201 drives the transmission shaft 202 to rotate clockwise. The transmission shaft 202 drives the limiting rotating blocks 211 and the limiting side gear 2 303 at both ends to rotate clockwise. The transmission shaft 202 drives the limiting side gear 2 303 to rotate clockwise. The transmission shaft 202 drives the rotating sleeve 1 208 to rotate clockwise through the limiting rotating block 211. The rotating sleeve 1 208 rotates clockwise, driving the side gear 1 207 to rotate clockwise. The side gear 1 207 rotates clockwise. The clockwise rotation drives the rotating gear 601 to rotate counterclockwise through the outer teeth. The counterclockwise rotation of the rotating gear 601 drives the short rod screw 602 to rotate counterclockwise through the rotating shaft. The counterclockwise rotation of the short rod screw 602 drives the long rod screw 603 to move downward through the thread. The long rod screw 603 moves downward and pulls the limit slider 605 downward through the rotating column 604. The limit slider 605 moves downward to make the rotating plate 103 rotate counterclockwise, so that the rotating plate 103 rotates counterclockwise to reset, so that the appropriate angle can be adjusted when working next time.
