[0025] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0026] An adjustable direction bucket tooth includes a tooth base 1. The tooth base 1 has symmetrically opened connecting through holes 2 on the rear side of the left and right sides. The tooth base 1 has a connecting groove 3 on the front side. The tooth base 1 has a connecting component 4 on the front side of the left and right sides. The connecting groove 3 has a connecting block 5 inside. The connecting block 5 has evenly opened adjustment holes 6 on the outer wall. The connecting block 5 has a tooth tip 7 at the front end.

[0027] In this embodiment, please refer to Figure 3 and 4 The connecting component 4 includes a fixing rod 401. A first telescopic sleeve 402 is provided on the front of the fixing rod 401, and a second telescopic sleeve 403 is provided on the back of the fixing rod 401. An auxiliary spring 404 is provided inside the first telescopic sleeve 402. A first telescopic rod 405 is slidably provided inside the first telescopic sleeve 402, and a second telescopic rod 406 is slidably provided inside the second telescopic sleeve 403. A pressing rod 407 is provided at the outer end of both the first telescopic rod 405 and the second telescopic rod 406. A first limiting rod 408 is provided on the lower side of the first telescopic rod 405, and a second limiting rod 409 is provided on the lower side of the second telescopic rod 406.

[0028] The tooth base 1 has a through hole corresponding to the fixed rod 401. The first limiting rod 408 and the second limiting rod 409 are both L-shaped. The inner ends of the first limiting rod 408 and the second limiting rod 409 are fixedly connected to the tooth base 1. The fixed rod 401 is adapted to the adjusting hole 6 so that the fixed rod 401 can enter the interior of the adjusting hole 6. The connecting block 5 is adapted to the connecting groove 3 so that the connecting block 5 can enter the interior of the connecting groove 3. The inner ends of the first telescopic rod 405 and the second telescopic rod 406 are respectively fixedly connected to the outer ends of the auxiliary spring 404. By setting the connecting groove 3, the connecting block 5 and the connecting assembly 4 on the adjustable bucket tooth, and by pressing the rod 407... The first telescopic rod 405 and the second telescopic rod 406 are pressed inwards respectively. When the first telescopic rod 405 and the second telescopic rod 406 retract into the inner side of the first limiting rod 408 and the second limiting rod 409, the fixing rod 401 can be pulled outwards to move it out of the adjustment hole 6. The tooth tip 7 can be disassembled and replaced by pulling it forward. The reverse operation can be used to install it. The installation and disassembly are relatively convenient, so it is easy to replace the tooth tip 7 when it is worn. After the fixing rod 401 is disassembled, the connecting block 5 can rotate inside the connecting groove 3, thereby driving the tooth tip 7 to rotate, so that it can be adjusted as needed. The overall device has a simple structure, is easy to operate, and has higher practicality.

[0029] The working process of this utility model is as follows: When using the adjustable bucket teeth, when the tooth tip 7 becomes worn and needs to be replaced, the pressing rod 407 is pressed inward. As the pressing rod 407 moves, it presses the first telescopic rod 405 and the second telescopic rod 406 inward respectively. When the first telescopic rod 405 and the second telescopic rod 406 retract into the inner side of the first limiting rod 408 and the second limiting rod 409, pulling the fixing rod 401 outward will remove it from the inside of the adjusting hole 6. Pulling the tooth tip 7 forward will allow it to be disassembled and replaced. During installation, the connecting block 5 is snapped into the connecting groove, and then... The side-pressing rod 407 is pressed. After the fixing rod 401 is inserted into the adjusting hole 6, the pressing rod 407 is loosened. The first telescopic rod 405 and the second telescopic rod 406 drive the pressing rod 407 to move outward under the force of the auxiliary spring 404. The first limiting rod 408 and the second limiting rod 409 limit the movement. The installation is completed. The installation and disassembly are relatively convenient, so it is easy to replace the tooth tip 7 when it is worn. After the fixing rod 401 is removed, the connecting block 5 can rotate inside the connecting groove 3, which can drive the tooth tip 7 to rotate and adjust it as needed.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
