[0007] In the above technical scheme, the jaw holder is provided with two jaw blocks, and the fixed surface of the jaw block faces the center hole of the jaw plate.

[0008] In the above technical scheme, limiting grooves are arranged on both sides of the slider, and the side part of the front cover plate is embedded in the limiting grooves.

[0009] In the above technical scheme, the base plate is provided with four front cover plates. The front cover plates are fan-shaped and are fixedly connected to the base plate by bolts.

[0010] A connecting rod hole is arranged in the middle of the slider groove, and the slider is connected to the transmission mechanism in the chuck body through the connecting rod hole.

[0011] In the above technical scheme, a jaw holder installation groove is arranged on the upper part of the slider, and an installation convex block on the lower part of the jaw holder is embedded in the jaw holder installation groove.

[0012] In the above technical solution, fine-tuning holes are provided at both ends of the slider. The fine-tuning holes are connected to the jaw holder mounting grooves, and the fine-tuning bolts in the fine-tuning holes abut against both ends of the lower mounting bumps of the jaw holder.

[0013] In summary, the beneficial effects of adopting the technical solution of the present utility model compared with traditional technical means are as follows: The present utility model eliminates the track of the jaw assembly in the prior art. The slider is directly arranged in the slider groove on the substrate, and both sides of the slider are limited by the front cover plate, so the structure is simpler, and disassembly, installation and maintenance are more convenient.
