An L-shaped plate 215 is provided above the sliding rod 214, and the bottom surface of the L-shaped plate 215 is fixedly connected to the top surface of the lifting plate 213.

[0035] The angle adjustment part 22 includes a motor 221, which is located on the top surface of the lifting plate 213. A small gear 222 is provided on the output end surface of the motor 221, and the small gear 222 is fixedly connected to the motor 221.

When the large gear 223 rotates, it drives the rotating rod 224, and the rotating rod 224 drives the turntable 225 to rotate. In this way, the fixture can achieve different processing heights to meet the processing requirements of different parts, and can be adjusted according to different processing angles, thereby improving processing efficiency and ensuring processing accuracy.

[0040] Example 2:

[0042] The fixing portion 32 includes a slider 321, and four sliders 321 are arranged on the left and right. The top surface of the slider 321 is fixedly connected to the bottom surface of the movable plate 315. The inner wall of the slider 321 is penetrated by a guide rod 322. The outer end surface of the guide rod 322 is fixedly connected to the inner surface of the outer mounting groove. The guide rod 322 is slidably connected to the slider 321. A clamping plate 323 is arranged above the guide rod 322, and the bottom surface of the clamping plate 323 is fixedly connected to the top surface of the movable plate 315.

[0043] Furthermore, in this embodiment, the clamp mechanism 3 utilizes the second motor 312 in the driving unit 31. The rotational power of the second motor 312 is transmitted to the bidirectional threaded rod 313. As the bidirectional threaded rod 313 rotates, the threaded block 314 mounted thereon begins to move due to the action of the threads. The movement of the threaded block 314 further drives the movable plate 315 connected thereto. The clamping plate 323 mounted on the movable plate 315 moves as the movable plate 315 moves. The clamping plate 323 slides along the surface of the guide rod 322 under the action of the slider 321. The guide rod 322 provides a stable movement path for the clamping plate 323, thereby clamping.

[0044] Furthermore, this embodiment uses the clamp mechanism 3 and the motor 2 312 in the driving part 31, so that the motor 2 312 drives the bidirectional threaded rod 313, and the bidirectional threaded rod 313 drives the threaded block 314, and the threaded block 314 drives the movable plate 315, so that the movable plate 315 drives the clamping plate 323 to slide on the surface of the guide rod 322 under the action of the slider 321, thereby achieving the clamping of the object.

[0045] When in use, it is placed on the U-shaped plate 311, and through the clamping mechanism 3, the motor 2 312 in the driving part 31 is used, and the rotational power of the motor 2 312 is transmitted to the bidirectional threaded rod 313. As the bidirectional threaded rod 313 rotates, the threaded block 314 installed thereon begins to move due to the action of the thread, and the movement of the threaded block 314 further drives the movable plate 315 connected thereto, and the clamping plate 323 installed on the movable plate 315 moves with the movement of the movable plate 315. The clamping plate 323 slides along the surface of the guide rod 322 under the action of the slider 321, and the guide rod 322 provides a stable moving path for the clamping plate 323, thereby clamping. After the clamping is completed, the angle adjustment mechanism 2 is used to use the motor in the lifting part 21 The telescopic rod 212 first starts the electric telescopic rod 212 in the lifting part 21. The telescopic movement of the electric telescopic rod 212 drives the lifting plate 213 to rise and fall, and the sliding rod 214 supports and guides the lifting plate 213 to rise and fall smoothly. As the lifting plate 213 rises and falls, the angle adjustment part 22 connected thereto is also driven to a suitable position. When the angle adjustment part 22 reaches a suitable position, the motor 221 is started, so that the motor 221 drives the small gear 222 to start rotating. Therefore, when the small gear 222 rotates, it will drive the large gear 223 to rotate. As the large gear 223 rotates, the rotating rod 224 connected thereto also starts to rotate. The rotation of the rotating rod 224 further drives the rotation of the turntable 225, thereby adjusting.
