[0032] a covering device 5, the covering device 5 being arranged on the outside of the positioning device 4 to protect the positioning device 4;

[0033] When replacing the tooth tip 2 after a long time of work, the covering device 5 is taken off from the outside of the positioning device 4, the positioning device 4 is exposed, then the positioning device 4 is rotated, the positioning device 4 and the tooth seat 1 are uncoupled, then the tooth tip 2 is taken off from the tooth seat 1, a new tooth tip 2 is sleeved on the outside of the tooth seat 1, the positioning device 4 is rotated, the positioning device 4 couples the tooth tip 2 and the tooth seat 1 together, finally the covering device 5 is placed on the outside of the positioning device 4 to protect the positioning device 4, so that the positioning tooth tip 2 avoids the entry of soil into the inside of the positioning device 4 when working, and the soil on the positioning device 4 needs to be removed when rotating the positioning device 4.

[0034] Embodiment 1:

[0035] The positioning device 4 comprises two fixed rods 40 respectively installed on the two sides inside the installation slot 3, and the outer side of the fixed rod 40 is provided with an external thread 41, and the two ends of the installation slot 3 are provided with internal threads 42 connected with the outer side of the external thread 41;

[0036] The fixed rod 40 is provided with a connecting device 43;

[0037] The connecting device 43 comprises a fixed hook 44 fixedly installed on the inner side of the fixed rod 40, and the fixed hook 44 is arranged in an arc shape, and the two sides of the tooth holder 1 are respectively fixedly installed with two positioning hooks 45 clamped with the two fixed hooks 44, and the two sides inside the tooth tip 2 are respectively provided with positioning grooves 46 slidably connected with the outer side of the two positioning hooks 45;

[0038] The outer side of the fixed rod 40 is fixedly installed with a rotating plate 47, the material of the rotating plate 47 is arranged as an iron plate, the rotating plate 47 is provided with a cross groove, and the outer side of the rotating plate 47 is fixedly installed with a positioning block 48, and the outer side of the tooth tip 2 is provided with an arc-shaped groove 49 slidably connected with the outer side of the positioning block 48;

[0039] When the tooth tip 2 is installed, the tooth tip 2 is sleeved on the outer side of the tooth holder 1, and the two positioning hooks 45 on the outer side of the tooth holder 1 are slid along the positioning grooves 46 to the position of the installation slot 3, and at this time the direction of the positioning block 48 on the rotating plate 47 is towards the upper side of the arc-shaped groove 49, so the position of the fixed hook 44 will not affect the positioning hook 45 entering the inside of the tooth tip 2;

[0040] The cross groove is rotated by inserting a tool into the inside of the cross groove, so that the fixed rod 40 rotates and advances at the same time, when the positioning block 48 is attached to the inside of the arc-shaped groove 49, and the positioning block 48 is placed towards the bottom of the arc-shaped groove 49, the fixed hook 44 and the positioning hook 45 are completely clamped.

[0041] The covering device 5 comprises a magnet piece 50 installed on the outer side of the rotating plate 47, and the outer side of the tooth tip 2 is provided with a circular groove 51 for placing the magnet piece 50, when the magnet piece 50 is placed in the circular groove 51, the outer side of the magnet piece 50 is flush with the outer side of the tooth tip 2, so that the magnet piece 50 will not be damaged when the tooth tip 2 is working in the earth, the magnet piece 50 covers the rotating plate 47, and the cross groove on the rotating plate 47 and the arc-shaped groove 49 on the tooth tip 2 will not enter the soil when the tooth tip 2 is working in the soil, which is convenient for workers to rotate the rotating plate 47;

[0042] When the magnet piece 50 is taken down, an iron block larger than the rotating plate 47 needs to be placed on the outer side of the magnet piece 50, so that the magnetic force is larger, and the magnet piece 50 can be taken off from the rotating plate 47.

[0043] Example 2:

[0044] The positioning device 4 includes two rubber pads 6 that are fixedly installed on both sides inside the mounting groove 3. A fixing rod 40 is installed inside the rubber pad 6, and a connecting device 43 is provided on the fixing rod 40.

[0045] A connecting device 43 is provided on the fixed rod 40;

[0046] The connecting device 43 includes a fixed hook 44 fixedly installed inside the fixed rod 40. The fixed hook 44 is arc-shaped. Two positioning hooks 45 that engage with the two fixed hooks 44 are fixedly installed on both sides of the tooth seat 1. Positioning grooves 46 that slide and connect with the outer sides of the two positioning hooks 45 are respectively provided on both sides of the inside of the tooth tip 2.

[0047] A rotating plate 47 is fixedly installed on the outside of the fixed rod 40. The rotating plate 47 is made of iron plate. A cross groove is provided on the rotating plate 47. A positioning block 48 is fixedly installed on the outside of the rotating plate 47. An arc groove 49 is provided on the outside of the tooth tip 2, which is slidably connected to the outside of the positioning block 48.

[0048] When working, place the fixing rod 40 inside the rubber pad 6. Use external force to strike the rotating plate 47 so that the positioning block 48 on the rotating plate 47 fits into the arc groove 49 and faces upward. After the positioning device 4 is installed and the tooth tip 2 and tooth seat 1 are connected, rotate the rotating plate 47. The rotating plate 47 drives the fixing hook 44 and the positioning hook 45 to engage and face downward. The rubber pad 6 has a certain elasticity, so the fixing rod 40 can rotate inside the rubber pad 6. When removing the tooth tip 2, rotate the rotating plate 47. The rotating plate 47 drives the tooth to move. The tooth tip 2 faces upward, so the tooth tip 2 can be removed and replaced with a new tooth tip 2.
