The fixed frame 305 is fixedly mounted on the inner wall of the steering seat 301, and the meshing gear 306 is mounted on the inner wall of the fixed frame 305. The first support frame 307 is fixedly mounted on the top surface of the steering shaft 303.

[0035] Rotating the hand crank 302 will drive the steering shaft 303, which in turn will drive the first support frame 307 to rotate to the desired position. During this process, the steering shaft 303 will also drive the drive gear 304, which will precisely mesh with the meshing gear 306, allowing the device to be flexibly adjusted to any direction, thus improving convenience.

[0036] The steering shaft 303 passes through the steering seat 301, and the drive gear 304 meshes with the meshing gear 306. The engagement of the drive gear 304 and the meshing gear 306 through the steering shaft 303 through the steering seat 301 improves the locking and fixing of the device.

[0037] The adjustment platform 4 includes a platform body 401, a support groove 402, support blocks 403, an ear plate frame 404, a platform 405, a support rod 406, and a second support frame 407.

An ear plate frame 404 is fixedly installed on one side of the top surface of the platform body 401, and a platform 405 is fixedly installed on the inner wall of the ear plate frame 404. A support rod 406 is fixedly installed on the bottom surface of the platform 405. A second support frame 407 is installed on one side of the platform body 401. By pushing the platform 405 upwards, one side of it rotates and tilts within the ear plate frame 404. At this time, the other end of the platform 405 separates from the second support frame 407, flips the support rod 406, and places the support rod 406 into the support groove 402. The support blocks 403 provide solid support for the support rod 406, thereby stably supporting the platform 405. This allows the device to be easily adjusted to various tilt angles to adapt to different processing operations, greatly improving the work efficiency and comfort of the staff.

[0038] The position of the support rod 406 corresponds to the position of the support groove 402, and the width of the support rod 406 matches the width of the support groove 402. By matching the position of the support rod 406 with the position of the support groove 402 and the width of the support rod 406 with the width of the support groove 402, the stability of the device is improved.

[0039] The positioning and clamping device 5 includes a slide groove 501, a guide rod 502, a slider 503, a clamping block 504, a screw 505, and a knob 506. The guide rod 502 is fixedly installed on the inner wall of the slide groove 501, and the slider 503 is sleeved on the outer periphery of the guide rod 502. The clamping block 504 is fixedly installed on the top surface of the slider 503. The screw 505 is fixedly installed on one side surface of the clamping block 504, and the knob 506 is fixedly installed on one side surface of the screw 505. By rotating the knob 506, the knob 506 drives the screw 505 to move smoothly along the axial direction. As the screw 505 moves, the clamping block 504 moves accordingly, thereby driving the slider 503 to slide along the inside of the slide groove 501 under the guidance of the guide rod 502. This ensures that the platform 405 and the clamping block 504 work together to safely and securely clamp the instrument, avoiding damage to the mechanical equipment caused by excessive movement, and preventing displacement, thus protecting the service life of the mechanical equipment and components.

[0040] The connection between the platform 405 and the screw 505 is provided with threads. The screw 505 moves axially according to the threads. During the movement, the clamping block 504 interacts with the platform 405 to clamp and fix it. The threads themselves have a locking function.

[0041] The device has two slides 501, two guide rods 502, and two sliders 503, and their positions are mirror-symmetrical. The slide 501 is fixedly connected to the platform 405. The screw 505 penetrates the inner wall of the platform 405, and the connection between the platform 405 and the screw 505 is threaded. The device's safety is improved by having two slides 501, two guide rods 502, and two sliders 503, and their positions are mirror-symmetrical. The slide 501 is fixedly connected to the platform 405, and the screw 505 penetrates the inner wall of the platform 405. The connection between the platform 405 and the screw 505 is threaded.

[0042] The working principle of this utility model is as follows:

[0043] When the device is in use, the processing instrument is placed on the top surface of the table 405. Then, the knob 506 is rotated, which drives the screw 505 to move axially. During the movement, the screw 505 drives the clamping block 504 to move, and the clamping block 504 drives the slider 503. The slider 503 moves along the guide rod 502 in the slide groove 501, and the instrument is fixed by the action of the table 405 and the clamping block 504. Next, the hand crank 302 is rotated according to the size and type of the instrument. The hand crank 302 drives the steering shaft 303, which drives the first support frame 307 to rotate. During rotation, the steering shaft 303 drives the drive gear 304, which drives the meshing gear. After rotating to the designated position, the drive gear 304 meshes with the meshing gear 306, and then pushes the pin on the bottom surface of the fixed frame 305. The pin locks the meshing gear 306 and rotates it to fix it, making the device easy to adjust to any direction. According to the processing position, the table 405 is pulled upward. One end of the table 405 rotates and tilts in the ear plate frame 404, and the other end of the table 405 separates from the second support frame 407. The support rod 406 is flipped over, and the bottom end of the support rod 406 is placed into the support groove 402. The support block 403 provides support force for the support rod 406, so that the support rod 406 supports the table 405, making the device easy to adjust to different tilt angles and facilitating the processing operation of the staff.
