The toothholder 100 includes a toothholder body 110, and a first leg portion 120 and a second leg portion 130 extending from the toothholder body 110 to both sides, respectively, and an opening portion is formed between the first leg portion 120 and the second leg portion 130, so that the toothholder 100 is U-shaped.

The support member 200 is inserted into the opening portion.

A mounting channel 600 extends through the support assembly 200, the first leg 120 and the second leg 130; the first leg 120 is provided with a first through hole 140, the second leg 130 is provided with a second through hole 150, the third leg 310 is provided with a third through hole 210, and the first through hole 140, the second through hole 150 and the third through hole 210 together form an installation channel 600.

The first fixing member 300 can be inserted into the mounting channel 600 along a predetermined mounting direction at a side 110 close to the tooth socket body, and the first fixing member 300 is tightly attached and fixed to the supporting member 200 at the side of the mounting channel 600 close to the tooth socket body 110. The mounting direction is a vertical direction in the present embodiment. The first fixing component 300 is used for fixing and driving the supporting component 200 to move, so that the connection between the tooth holder 100 and the supporting component 200 is tighter and firmer.

The second fixing component 400 can be inserted into the mounting channel 600 along a predetermined mounting direction on the side 110 far away from the tooth holder body, and the second fixing component 400 is tightly attached and fixed on the tooth holder 100 on the side of the mounting channel 600 far away from the tooth holder body 110. The second fixing member 400 is closely attached to the tooth holder 100 and the supporting member 200 at the other side with respect to the first fixing member 300. The first and

second fixing assemblies

300 and 400 fix the block 100 and the supporting assembly 200 in the installation passage 600 from two directions.

The adjusting mechanism 500 is movably inserted between the first fixing component 300 and the second fixing component 400, the adjusting mechanism 500 includes a first side surface slidably engaged with the third side surface of the first fixing component 300 and a fourth side surface threadedly engaged with the second side surface of the second fixing component 400, and the adjusting mechanism 500 is wedge-shaped. Preferably, the first side face forms an angle with the mounting direction, and the fourth side face is parallel to the mounting direction. Another alternative is that the first side and the fourth side each form an angle with the mounting direction.

Specifically, the adjusting mechanism 500 is a right trapezoid with a wide top and a narrow bottom. Therefore, when the adjustment mechanism 500 is moved downward in the installation direction, the first fixing member 300 is moved toward the block body 110 in the horizontal direction, so that the coupling of the block 100 and the support member 200 is more tightly made. And the adjusting mechanism 500 is arranged between the first fixing assembly 300 and the second fixing assembly 400, so that the implementation space is large and the operation is convenient.

Further, after the adjustment mechanism 500 is installed, the adjustment mechanism 500 is completely received within the installation channel 600 without extending beyond the outer edges of the first leg 120 and the second leg 130. Therefore, when the wear assembly is used for excavating, the adjusting mechanism 500 cannot collide with materials such as stones and earth due to the size exceeding the outer edges of the first leg portion 120 and the second leg portion 130, and the materials are loosened and failed.
