[0012] Beneficial Effects
[0013] 1. In the prior art, in the existing manufacturing and slotting technology, the positioning of plastic parts is usually to ensure the precise alignment and fixation of components during the slotting process. Using pins for positioning is a common method, but it also brings some challenges and limitations. When disassembling and reinstalling plastic parts that use pins for positioning, a series of steps are often required. First, it is necessary to ensure that the pins and corresponding holes are aligned, which requires precise manual operation or special tools. Secondly, the pins must be fully inserted or pulled out, which requires a certain amount of force. Especially after long-term use, the pins will become difficult to move. In addition, if the pins are damaged or lost, they need to be replaced with new pins, which increases the complexity and cost of maintenance.

At this time, when the limit block is moved outward by external force, the force applied to the pushing plate is downward, which indirectly reinforces the limit block, thereby reducing the time for fixing the plastic part during processing and improving processing efficiency.
[0014] 2. In the prior art, the processing of plastic parts usually requires specific fixtures and equipment to ensure the accuracy and efficiency of the processing. However, these equipment and fixtures are only applicable to round tube plastic parts of the same diameter. They are not flexible and convenient when processing round tube plastic parts of different diameters. This limits production efficiency and leads to some problems in the processing process. Special fixtures and equipment cannot adapt to round tube plastic parts of different diameters. This means that each time the processing object is changed, the corresponding fixture needs to be replaced, which not only increases the production preparation time, but also causes delays in the production process. Errors and low production efficiency. When it is necessary to process round tube plastic parts of various diameters, frequent replacement of fixtures will lead to production interruptions, affecting the overall production efficiency and progress.

[0026] In the prior art, in the existing manufacturing and slotting technologies, the positioning of the plastic part 2 is usually to ensure the precise alignment and fixation of the component during the slotting process. Using pins for positioning is a common method, but it also brings some challenges and limitations. When disassembling and reinstalling the plastic part 2 using pins for positioning, a series of steps are often required. First, it is necessary to ensure that the pin and the corresponding hole are aligned, which requires precise manual operation or special tools. Secondly, the pin must be fully inserted or pulled out, which requires a certain amount of force. Especially after long-term use, the pin will become difficult to move. In addition, if the pin is damaged or lost, it is necessary to replace it with a new pin, which increases the complexity and cost of maintenance. By installing a new clamping device 3, when the user installs the plastic part 2, the handle 307 is pushed outward. The push plate 306 is driven to move outward, so that the push plate 306 moves along the front end inclined surface of the limit block 303 until it reaches the limit groove 304, and then pushed outward again, the push plate 306 drives the front end protrusion of the limit block 303 to rotate outward, and the limit block 303 rotates at this time, so that the clamping block 305 at the bottom of the limit block 303 moves outward, and then the plastic part 2 is placed in the limit platform 1, and the carrying rod is pushed in the opposite direction until the push plate 306 drives the limit block 303 and the clamping block 305 to clamp the plastic part 2, and at the same time, the push plate 306 moves to the front end inclined surface of the limit block 303 to complete the fixation. At this time, when the limit block 303 is moved outward by the external force, the force applied to the push plate 306 is downward, which indirectly reinforces the limit block 303, thereby reducing the time for fixing the plastic part 2 during the processing and improving the processing efficiency.
[0027] The working principle of the utility model is as follows: when the user installs the plastic part, the handle 307 is pushed outward, which drives the push plate 306 to move outward, so that the push plate 306 moves along the front end inclined surface of the limit block 303 until it reaches the limit groove 304. At this time, it is pushed outward again, and the push plate 306 drives the front end protrusion of the limit block 303 to rotate outward. At this time, the limit block 303 rotates, so that the pressing block 305 at the bottom of the limit block 303 moves outward. Then, the plastic part is placed on the limit platform, and the carrying rod is pushed in the reverse direction until the push plate 306 drives the limit block 303 and the pressing block 305 to press the plastic part. When the limit block 303 is moved outward by the external force, the force applied to the push plate 306 is downward, which indirectly reinforces the limit block 303. When the plastic part is clamped, the round tube part of the plastic part is placed in the round groove, and the desktop button is pressed to start the low-speed motor 407. The turntable 402 is rotated with the help of the worm 408. Since one end of the clamping arm 405 is connected to the shaft 403 and the turntable 402 rotates, the angle of the slider 404 changes and moves inward along the clamping arm 405. Then, the plastic part is clamped with the help of the rolling wheel 406.
