The other end of the gear shaft 8 extends out of the body shell 1 and is connected to a gear 10. The gear 10 meshes with the rack on the grinding head body 3. A cover shell 11 is arranged on the side of the body shell 1 opposite to the gear 10. A toggle assembly and a transmission assembly are arranged in the cover shell 11. The toggle assembly can drive the first clutch 6 to slide through the transmission assembly to engage or disengage the first clutch 6 with the second clutch 7.

[0022] Based on the above structure, when the toggle assembly drives the first clutch 6 to slide toward the second clutch 7 through the transmission assembly, so that the first clutch 6 is engaged with the second clutch 7, the hand-grip wheel 9 drives the worm 4 to rotate, and then under the sequential transmission of the worm 4, the worm wheel 5, the first clutch 6, the second clutch 7, the gear shaft 8, and the gear 10, the manual lateral feed of the grinding head body 3 is achieved through the engagement of the gear 10 with the rack on the grinding head body 3; when the toggle assembly drives the first clutch 6 to slide away from the second clutch 7 through the transmission assembly, so that the first clutch 6 is separated from the second clutch 7, the grinding head body 3 can be hydraulically driven to feed laterally without affecting the structure of the worm 4 and the worm wheel 5, thereby finally realizing manual and hydraulic switching during the lateral feed of the grinding head body 3.

[0023] like Figure 2 As shown, both ends of the worm 4 are supported in the body shell 1 through the first bearing 12, and a first positioning sleeve 13 is sleeved on the worm 4 between the two first bearings 12, and the first positioning sleeve 13 is connected to the body shell 1 through a screw, and the worm 4 is positioned by the first positioning sleeve 13. In addition, one end of the worm 4 extending out of the body shell 1 is sleeved with a limiting sleeve 14 and a first locking nut 15 in sequence, wherein the first locking nut 15 is threadedly connected to the worm 4 and abuts against one end of the limiting sleeve 14 near the first locking nut 15, and a pressure cap 16 connected to the body shell 1 is sleeved on the limiting sleeve 14, and one end of the limiting sleeve 14 away from the first locking nut 15 is limited in the pressure cap 16, and the worm 4 is limited by the cooperation of the limiting sleeve 14, the first locking nut 15 and the pressure cap 16.

[0025] In order to realize that the first clutch 6 can rotate synchronously with the worm gear 5 and can also slide, Figure 1 As shown, a slide groove 20 is opened on the inner wall of the worm wheel 5 along the sliding direction of the first clutch 6, and a flat key 21 slidably connected to the slide groove 20 is embedded in the outer wall of the first clutch 6, so that the first clutch 6 and the worm wheel 5 rotate synchronously through the flat key 21, and the first clutch 6 can slide through the cooperation between the flat key 21 and the slide groove 20.

[0026] Both ends of the gear shaft 8 are supported in the body shell 1 through third bearings 22 , and a second positioning sleeve 23 is sleeved on the gear shaft 8 between the two third bearings 22 . The second positioning sleeve 23 is connected to the body shell 1 through screws, and the gear shaft 8 is then positioned through the second positioning sleeve 23 .

[0027] like Figure 1 As shown, a plug hole 24 is provided at one end of the first clutch 6 away from the second clutch 7, and the transmission assembly includes a pull rod 25 and a first compression spring 26. One end of the pull rod 25 is inserted into the plug hole 24 and fixedly connected to the first clutch 6, and the other end of the pull rod 25 passes through the second locking nut 19 and is connected to a baffle 27. The toggle member acts on the baffle 27. The first compression spring 26 is sleeved on the pull rod 25, and the two ends of the first compression spring 26 are respectively in contact with the bottom of the plug hole 24 and the second locking nut 19. The pull rod 25 is pulled in a direction away from the second clutch 7, and the first clutch 6 and the second clutch 7 can be separated by the pull rod 25. The first compression spring 26 is then compressed, and the pull rod 25 is released. The first compression spring 26 pushes the first clutch 6 toward the second clutch 7 through its own restoring force, and the first clutch 6 and the second clutch 7 can be engaged.

[0028] like Figure 3 , Figure 4 As shown, in order to achieve the cooperation between the toggle assembly and the transmission member, the toggle assembly includes a toggle block 28 , an adjustment rod 29 , a toggle rod 30 , a push rod 31 , a second compression spring 32 and a limit nut 33 . The shift block 28 is rotatably arranged at the bottom of the cover shell 11, one end of the shift block 28 extends out of the cover shell 11 and is connected to the adjusting rod 29, and the other end of the shift rod 30 is connected to an upright shift rod 30. The shift rod 30 is located on the side of the baffle plate 27 close to the first clutch 6 and abuts against the baffle plate 27. The inner wall of the cover shell 11 is provided with a sliding hole 34 opposite to the shift block 28, one end of the push rod 31 is inserted into the sliding hole 34 and extends out of the cover shell 11, and the other end of the push rod 31 is connected to a stopper 35 slidably connected to the sliding hole 34. The end of the push rod 31 extending out of the cover shell 11 is threadedly connected to a limit nut 33 that can abut against the cover shell 11. The second compression spring 32 is sleeved on the push rod 31 in the sliding hole 34, and both ends of the compression spring respectively abut against the bottom of the sliding hole 34 and the stopper 35. The end opposite to the shift block 28 is conical, and the conical end of the stopper 35 extends toward the shift block 28 and can be slidably connected with the end of the shift block 28.

[0029] like Figure 4When the adjusting rod 29 drives the shift block 28 to rotate, the shift block 28 will slide and contact with the tapered end of the stop block 35, and then the shift block 28 will push the stop block 35 out of the cover shell 11, so that the stop block 35 and the push rod 31 move out of the cover shell 11, and the limit nut 33 will move away from the cover shell 11, and the second compression spring 32 will be compressed. When the end of the shift block 28 close to the stop block 35 rotates to the other side of the stop block 35, the second compression spring 32 will push the stop block 35 toward the shift block 28 through its own restoring force until the limit nut 33 abuts against the cover shell 11, so that the stop block 35 blocks the shift block 28 to limit the shift block 28. In this reciprocating operation, the position of the end of the shift block 28 close to the stop block 35 on both sides of the stop block 35 can be switched back and forth. In the process of switching the position of the shift block 28, the shift block 28 can drive the shift rod to move, thereby switching the position of the shift rod 30. When the shift rod 30 moves so that the shift rod 30 abuts against the baffle plate 27 and drives the baffle plate 27 to move away from the first clutch 6, the baffle plate 27 pulls the pull rod 25 in the direction away from the first clutch 6, and then drives the first clutch 6 away from the second clutch 7 through the pull rod 25, so that the first clutch 6 and the second clutch 7 are in a closed position. Figure 1 In the separation state shown in the figure, the grinding head body 3 can be hydraulically driven to feed laterally. When the lever 30 moves in the opposite direction, the first compression spring 26 will push the first clutch 6 to the second clutch 7 by its own restoring force, so that the first clutch 6 can be engaged with the second clutch 7. In this way, the grinding head body 3 can be manually driven to feed laterally. Finally, the manual and hydraulic switching of the grinding head body 3 during the lateral feed can be realized by switching the position of the lever 30 through the adjusting rod 29.
