Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1, as shown in fig. 1 and 2:

a connecting structure for a bucket tooth and a tooth holder comprises a bucket tooth 1 and a tooth holder 2, wherein a connecting groove is formed in the bucket tooth 1 and used for being inserted into one end of the tooth holder 2, and a deformed steel bar locking pin 3 is arranged between the connecting groove and the tooth holder 2 and is connected with the connecting groove and the tooth holder;

set up the lockpin groove 4 respectively in the both sides of spread groove for installation screw-thread steel lockpin 3, the mode that adopts threaded connection is simple effective, sets up a constant head tank I6 in screw-thread steel lockpin 3's bottom, sets up integrated into one piece's protruding piece 5 in the one end of toothholder 2, protruding piece 5 insert in constant head tank I6 can.

Example 2, as shown in fig. 1 and 3:

compared to embodiment 1, the internal structure is changed as follows: the positioning groove I6 and the protruding block 5 are eliminated, the bottom end of the deformed steel bar lock pin 3 is provided with the integrally formed protruding head 7, the positioning groove II 8 is formed in one end of the gear seat 2, and the protruding head 7 is inserted into the positioning groove II 8.

Example 3, as shown in fig. 1 and 4:

compared to embodiment 1, the internal structure is changed as follows: the lockpin groove 4 of constant head tank I6, protruding piece 5 and spread groove both sides has been cancelled, changes to offer lockpin groove 4 alone in one side of spread groove, and the one end of screw-thread steel lockpin 3 sets up integrated into one piece's extension head 31 simultaneously, offers perforation 9 in the one end of toothholder 2, offers position groove III 10 in the opposite side of spread groove, and it can to peg graft with constant head tank III 10 after passing perforation 9 with extension head 31.

Example 4, as shown in fig. 5 and 6:

compared with the embodiment 3, the whole is basically the same, except that: the top end of the connecting groove is provided with a lock pin groove 4, the bottom end of the connecting groove is provided with a positioning groove III 10, and the directions and the positions are different.

The specific principle is as follows: the deformed steel lock pin 3 is screwed on the lock pin groove 4, and a concave end (a positioning groove I5) or a convex end (a convex head 7 and an extension head 31) at the front end of the deformed steel lock pin 3 is in contact with a positioning block (a convex block 5) or a positioning groove (a positioning groove II 8 and a positioning groove III 10) on the tooth holder 2, so that the effect of connecting the bucket tooth and the tooth holder and connecting the reamer tooth and the tooth holder is achieved;
