Description

Technical Field

[0001] This invention relates to the technical field of metal stamping, and in particular to a stamping device with adjustable range, magnetic clamp, and vibration reduction. Background Technology

[0002] Metal stamping is a highly efficient manufacturing process that uses dies and stamping equipment to apply external force to metal sheets, causing them to separate or plastically deform, thereby obtaining parts of the required shape and size. This process is widely used in the automotive, home appliance, electronics, and aerospace industries, and has significant advantages such as high production efficiency, high material utilization, and good part consistency. Common stamping processes include shearing, bending, deep drawing, and flanging, which are usually completed by special equipment such as punch presses in conjunction with precision dies.

[0003] Most stamping equipment on the market has a fixed stroke or can only be manually adjusted within a narrow range. The adjustment process is cumbersome and inefficient, making it difficult for the equipment to adapt to diverse production requirements of different materials, thicknesses, and processes. This limits its flexible manufacturing capabilities and fails to meet the demands of modern manufacturing for efficient switching and multi-process integration. During equipment inspection, maintenance, or mold replacement, operators need to work inside the mold. Due to gravity or uncontrolled sliding of the slider due to misoperation, it is easy to cause safety accidents such as pinching or crushing injuries. The high-speed heavy-load impact during the stamping process will cause strong vibrations, which will not only affect the accuracy and service life of the equipment itself, but also interfere with the high-precision sensors installed on the equipment, affecting the reliability of data acquisition and closed-loop control. Summary of the Invention

[0004] In order to address the shortcomings of existing metal stamping equipment in terms of flexible processing, safety assurance, and vibration resistance, this invention provides a stamping equipment with adjustable range, magnetic clamp, and vibration reduction.

[0005] The present invention provides a stamping device with adjustable stroke, magnetic clamp, and vibration reduction, which adopts the following technical solution:

[0006] A stamping device with adjustable stroke, magnetic clamping, and vibration damping includes a support assembly, an adjustable stroke device, a locking detection device, a magnetic clamping device, and a vibration damping device. The support assembly includes a lower housing, a slide rail, a slider A that moves on the slide rail, and an upper support. The slide rail is welded to the lower housing, and the upper support is welded to the slide rail. The adjustable stroke device is mounted on the upper support of the support assembly and connected to the slider A via a slide rod. The slider A has symmetrically arranged circular blind holes on both sides. The locking detection device is mounted on the slide rail and the slider A of the support assembly. The magnetic clamping device is mounted on the support assembly. Above the lower housing, the vibration damping device is installed below the lower housing of the support device; the adjustment device includes a turntable, a crank, a lead screw, a transmission plate, and a support rod. The crank is mounted on the turntable, one end of the transmission plate is connected to the crank, and the other end of the transmission plate is hinged to the middle of the slide rod. A support rod is installed in the middle of the transmission plate. The upper end of the support rod is fixed to the upper support via a rotating shaft, and the lower end of the support rod is connected to the transmission plate, with the connection point serving as the swing fulcrum of the transmission plate; the locking device includes a concave plate, a protrusion, and a rotating rod. The concave plate is welded to... On the slide rail, the rotary rod is welded to the protrusion, and a rotating shaft is welded to the inner side of the protrusion. The protrusion is installed in the circular blind hole of the slider A through the rotating shaft. The magnetic clamping device includes a control box, a sleeve A, an electromagnet, a spring A, and a pin B. The pin B is welded to the upper surface of the lower housing. The sleeve A is installed on the upper end of the pin B, and the spring A is installed inside the sleeve A. The sleeve A and the pin B are elastically connected to each other through the spring A. The electromagnet is installed on the upper end face of the sleeve A and is controlled by the control box. The reduction... The vibration device includes a sleeve B, a base rod, a spring B, a safety pin, a guardrail, and a base. The base is located below the lower housing. Guardrails are provided on the outer sides of the base and the lower housing. A rectangular through slot is opened on the side of the sleeve B, and a circular through hole is opened on the side of the base rod. The sleeve B is fitted onto the base rod and connected by a safety pin. The safety pin is installed in the circular through hole of the base rod and can move freely up and down in the through slot of the sleeve B. A spring B is provided at the upper end of the base rod. The upper end of the sleeve B is connected to the lower housing by bolts. The base rod is welded to the base.

[0007] The stroke adjustment device achieves precise adjustment of the stamping stroke through the linkage of a turntable, crank, lead screw, and transmission plate. This design ensures a smooth and reliable stroke adjustment process, allowing for rapid adjustment of the stamping stroke according to different process requirements, thus improving process adaptability and production efficiency. The locking device, composed of a concave plate, a protrusion, and a rotating rod, effectively prevents the slider A from loosening or accidentally moving during operation, maintenance, or shutdown, ensuring the equipment is fixed during maintenance and preventing injury to maintenance personnel. The mechanical locking method enhances the equipment's safety performance, avoiding safety hazards caused by misoperation or malfunction. The magnetic clamp device utilizes an electromagnet and spring A to achieve rapid workpiece positioning and release, greatly improving the stamping process. The automation level of the process is high. The control box precisely controls the electromagnets, making the clamping process efficient and stable, reducing manual intervention and improving production efficiency. The vibration damping device adopts a multi-layer spring and safety pin linkage structure to effectively absorb the vibration and impact generated during the stamping process, reducing the impact on the main structure of the equipment and high-precision sensors, reducing equipment operating noise, protecting equipment and infrastructure, and extending service life. The guardrail design further enhances safety protection performance and reduces equipment damage caused by vibration. The support device adopts a welded structure with high overall strength, ensuring the stability and safety of the stamping operation. The slide rail and slider A fit tightly, making the movement smooth and facilitating later maintenance and adjustment.

[0008] Furthermore, the slide rod is a stepped rod that is thicker in the middle and thinner at both ends. The slide rod has square through holes on the left and right sides of the middle part, and a circular through hole in the middle of the front part. The transmission plate is installed in the square through hole in the middle part of the slide rod and is hinged by pin A.

[0009] The slide bar adopts a stepped structure that is thicker in the middle and thinner at both ends, making it less prone to bending and deformation during operation, thus improving the stability and durability of the device. The square through-hole design facilitates reliable installation and precise positioning between the transmission plate and the slide bar. The hinged connection via pin A enables flexible hinged movement between the transmission plate and the slide bar, improving transmission efficiency while ensuring a firm connection. The thickened design in the middle gives the slide bar higher strength and fatigue resistance in areas of concentrated stress, effectively distributing impact loads and extending the service life of key components.

[0010] Furthermore, the transmission plate has through groove B and through groove A in the middle and at the end, respectively. Through groove B is an arc-shaped groove. The lower end of through groove B has a groove. There are 7 grooves in through groove B and they are arranged at equal intervals. The end of the support rod has a protrusion inside. The protrusion inside the end of the support rod is connected to the groove in through groove B.

[0011] The arc-shaped design of slot B and the seven equally spaced grooves allow the protrusion at the end of the support rod to precisely engage with any one of the grooves, enabling multi-level stroke adjustment to meet the different stroke requirements of various stamping processes. This multi-level design makes the stroke adjustment process convenient and precise, improving the adaptability and flexibility of the equipment. The engagement of the internal protrusion at the end of the support rod with the groove of slot B effectively prevents the transmission plate from accidentally sliding due to vibration or impact during operation, ensuring that the adjusted position is firm and reliable. This mechanical limiting and locking structure enhances the safety and stability of the equipment under high-intensity and frequent stamping conditions, reducing the occurrence of failures. During adjustment, simply push the protrusion at the end of the support rod to slide it into the designated groove in the arc-shaped slot to complete the stroke length switching. The operation is intuitive and clear, reducing manual judgment and adjustment errors.

[0012] Furthermore, the through groove A is a straight groove, and there is a margin for left and right movement between the through groove A and the pin A. The length of the through groove B is 5 times the length of the through groove A.

[0013] The through groove A is a straight groove, and a certain amount of lateral movement is reserved between it and the pin A, so that the transmission plate can be adjusted laterally to a limited extent during assembly and movement, to compensate for machining and assembly errors, to ensure smooth operation of the overall mechanism, and to reduce jamming and uneven force. Since there is a movement allowance between the through groove A and the pin A, the assembly and disassembly process can be more flexible, and it is convenient to insert, remove and position the pin A.

[0014] Furthermore, a slider B is installed in the middle of the support rod. The support rod and slider B are connected by a rotating shaft. The support rod and slider B can rotate freely around the rotating shaft. The slider B has an internal thread and is connected to a lead screw through the internal thread. The slider B is fixedly connected to the rotating shaft and is slidably inserted into the strip groove on the support rod through the rotating shaft.

[0015] The internal thread of slider B engages with the lead screw. By rotating the lead screw, slider B can be driven to move precisely along the lead screw axis, achieving precise linear adjustment of the support rod position. Compared with traditional pin positioning or fixed hole structures, the adjustment is more continuous and refined, meeting the requirements of high-precision processes. By rotating the lead screw, slider B can be easily pushed to move along the strip groove to achieve the positioning adjustment of the support rod, eliminating the tediousness of repeated disassembly and assembly, improving the convenience and efficiency of operation, and is especially suitable for occasions that require frequent adjustments.

[0016] Furthermore, two strip-shaped guide grooves are symmetrically opened on the inner side of the sleeve A, and a strip-shaped protrusion is provided on the side of the pin B corresponding to the guide groove. The sleeve A and the pin B are mutually inserted and slidably connected through the guide groove and the strip-shaped protrusion.

[0017] The strip guide groove and the strip protrusion on pin B cooperate to ensure that pin B can only slide linearly along the groove direction in sleeve A, effectively preventing pin B from rotating or deviating. Through the limit sliding connection, the movement of pin B in sleeve A is more controlled, reducing shaking and gaps, improving the stability and motion quality of the whole machine, and making it suitable for high-precision machinery or automated equipment.

[0018] Furthermore, the sleeve A moves up and down along the pin B, the upper surface of the electromagnet contacts the workpiece, and the electromagnet is located on the upper surface of the sleeve A.

[0019] The electromagnet is located on the upper surface of sleeve A. By turning on or off the power, it can automatically attract or release the workpiece, realize automatic mechanical assembly, and facilitate the positioning and demolding of the workpiece.

[0020] Furthermore, the number of concave plates on a single slide rail is at least two, the rotating shafts of the rotary rod and the protrusion are arranged vertically, the protrusion is rotatably connected to the slider A through the rotating shaft, the cross-section of the protrusion is a convex structure, the cross-section of the concave plate is a concave structure, the protrusion and the concave plate correspond to and match each other with a clearance fit, and the rotary rod controls the protrusion to switch between 0° and 90°.

[0021] The convex and concave plates, through convex-concave matching and clearance fit, can achieve precise limiting and locking, effectively preventing the slider A from moving unexpectedly along the slide rail, improving the safety and stability of equipment operation. Controlled by a rotary rod, the convex can switch between 0° and 90°. When the rotary rod is rotated to 0°, the convex can be inserted into the concave plate to lock. When rotated to 90°, the convex is disengaged from the concave plate to unlock. The entire operation process is simple and quick, facilitating rapid clamping or release. At least two concave plates are set on a single slide rail, enabling multi-point locking or hierarchical positioning, meeting multiple safety and positioning requirements under different working conditions, and improving the flexibility and applicability of the system.

[0022] Furthermore, there are 4 guardrail panels arranged at the four corners of the lower box body, and 12 bottom bars and sleeves B. The bottom bars and sleeves B are arranged symmetrically in groups of 6 below the lower box body, with each group of bottom bars and sleeves B arranged at equal horizontal and vertical intervals.

[0023] The four corner guardrails are reasonably distributed at the four corners of the lower box, which can effectively prevent equipment or items from slipping or colliding, enhance the protection around the lower box, and improve the safety and stability of the overall structure. The 12 bottom bars and sleeves B are symmetrically arranged in groups of 6, and are evenly spaced horizontally and vertically, which makes the stress under the entire lower box more uniform, significantly improves the load-bearing capacity, reduces local stress concentration, and extends the service life of the equipment.

[0024] In summary, the present invention has the following beneficial technical effects:

[0025] 1. The stroke adjustment device adopts a linkage structure of turntable, crank, lead screw and transmission plate to achieve precise and continuous adjustment of the stamping stroke, which can meet various process requirements and improve the process adaptability and production efficiency of the equipment.

[0026] 2. The mechanical locking structure of the inspection and locking device can effectively prevent the slider A from moving accidentally during maintenance or shutdown, avoiding safety hazards and improving safety during maintenance and operation.

[0027] 3. The magnetic clamping device uses electromagnets and springs to achieve rapid positioning and automatic release of workpieces, reducing manual operation and improving stamping cycle time and automation level.

[0028] 4. The vibration damping device effectively absorbs impact and vibration through the linkage of multiple layers of springs and safety pins, reducing damage to equipment and foundations and extending the overall service life.

[0029] 5. The support device adopts a fully welded structure, with the slide rail and slider A closely matched, resulting in strong overall rigidity and smooth movement, effectively ensuring the stability of the stamping operation and the precision of the finished product.

[0030] 6. The stepped thickened design of the slide bar, the multi-level adjustment of the transmission plate, and the screw linkage of the slider B all facilitate quick positioning and adjustment, taking into account the flexibility and ease of operation under various working conditions.

[0031] 7. The bottom bars and sleeves B are arranged symmetrically and at equal intervals, and the guardrails are distributed at the four corners, so that the lower box body is evenly stressed and the structure is stable, which facilitates maintenance and repair and improves the reliability of the equipment.

[0032] 8. Guardrails prevent items from slipping or colliding, guide grooves and strip protrusions prevent parts from rotating or shifting, limit sliding connections improve motion accuracy, and multiple protective measures ensure the safe and reliable operation of the equipment.

[0047] The magnetic clamp device includes a control box 3, a sleeve A4, an electromagnet 30, a spring A31, and a pin B28. The pin B28 is welded to the upper surface of the lower housing 16. The sleeve A4 is installed on the upper end of the pin B28. The spring A31 is installed inside the sleeve A4. The sleeve A4 and the pin B28 are elastically connected to each other through the spring A31. The electromagnet 30 is installed on the upper end face of the sleeve A4 and is controlled by the control box 3.

[0048] The vibration damping device includes a sleeve B1, a base rod 33, a spring B29, a safety pin 10, a guardrail 2, and a base 17. The base 17 is located below the lower housing 16. The base 17 and the lower housing 16 are provided with guardrail 2 on their outer sides. The sleeve B1 has a rectangular through groove on its side, and the base rod 33 has a circular through hole on its side. The sleeve B1 is fitted onto the base rod 33 and connected by the safety pin 10. The safety pin 10 is installed in the circular through hole of the base rod 33 and can move freely up and down in the through groove of the sleeve B1. The upper end of the base rod 33 is provided with a spring B29. The upper end of the sleeve B1 is connected to the lower housing 16 by bolts. The base rod 33 is welded to the base 17.

[0049] The slide rail 11 is precisely welded to the lower housing 16, ensuring that the slide rail 11 is parallel and the weld is firm without any false welds. The upper bracket 8 is welded and installed above the slide rail 11, ensuring that it is perpendicular to the slide rail 11 and stable. The slider A12 is installed on the slide rail 11 and can slide freely along the slide rail 11. The circular blind holes on both sides are checked to ensure that the hole diameter matches the rotating shaft of the subsequent locking device protrusion 5. The upper mold 15 is installed on the bottom surface of the slider A12 and moves up and down with the slider A12.

[0050] A turntable 9 is installed at a predetermined position on the upper bracket 8. The turntable 9 is fixedly connected to the crank 21 to ensure flexible rotation. One end of the crank 21 is connected to the transmission plate 18, and the other end of the transmission plate 18 is hinged to the middle of the slide rod 7 to ensure smooth movement of the hinged part. The upper end of the support rod 23 is fixed to the upper bracket 8 with a rotating shaft, and the lower end is connected to the middle of the transmission plate 18 and serves as the swing fulcrum of the transmission plate 18. The lead screw 22 is installed and fixed to the transmission components of the stroke adjustment device for adjusting the stroke.

[0051] The concave plate 6 is welded to the side of the slide rail 11, and its position should correspond to the movement trajectory of the slider A12. The protrusion 5 is installed in the circular blind holes on both sides of the slider A12 through the rotating shaft welded to its inner side, so that it can rotate on the slider A12. The rotating rod 27 is welded to the protrusion 5, which facilitates manual operation or automatic control of locking and unlocking.

[0052] Pin B28 is welded to the upper surface of the lower housing 16 to ensure it is perpendicular to the housing. Pin B28 is arranged around the edge of the lower mold 13. The lower mold 13 and the upper mold 15 are correspondingly closed. The lower mold 13 is fixedly set on the lower housing 16. Sleeve A4 is fitted on the upper end of pin B28.

After the process is completed, the power is cut off and the device is released to assist in material removal or cleaning. The operator adjusts the stroke according to the workpiece requirements, and precise adjustment is achieved through the lead screw 22 and the stroke adjustment device. The locking device can be operated manually or automatically to control the stamping stroke termination point and prevent the equipment from running beyond its range. Example 2

[0055] Based on Example 1, the following is added:

[0056] Reference Figure 1 and Figure 2 The slide rod 7 is a stepped rod that is thicker in the middle and thinner at both ends. The slide rod 7 has square through holes on the left and right sides of the middle part and a circular through hole in the middle of the front part. The transmission plate 18 is installed in the square through hole in the middle part of the slide rod 7 and is hinged by the pin A19.

[0057] Reference Figure 2 and Figure 6 The transmission plate 18 has through grooves B25 and A24 in the middle and at the end, respectively. The through groove B25 is an arc-shaped groove. The lower end of the through groove B25 has a groove 26. There are 7 grooves 26 in the through groove B25 and they are arranged at equal intervals. The support rod 23 has a protrusion inside the end. The protrusion inside the end of the support rod 23 is connected to the groove 26 in the through groove B25.

[0058] Reference Figure 2 and Figure 6 The through groove A24 is a straight groove, and there is a margin for left and right movement between the through groove A24 and the pin A19. The length of the through groove B25 is 5 times the length of the through groove A24.

[0059] Two thin rods are welded to the ends of a thick rod to form a stepped slide rod 7. This slide rod 7 is then inserted into the connection between the slider A12 and the upper bracket 8. The square through holes on the left and right sides of the middle of the slide rod 7 are checked to ensure they are precisely aligned with the installation position of the transmission plate 18. The transmission plate 18 is then passed through the square through hole in the middle of the slide rod 7, with its end aligned with the circular through hole in the middle of the front of the slide rod 7. The pin A19 is then inserted and hinged to the square through hole in the front of the slide rod 7 with the square through hole in the transmission plate 18. This ensures proper installation and that the pin A19 can rotate freely, guaranteeing reliable linkage.

[0060] Inspect the arc-shaped through groove B25 in the middle of the transmission plate 18 and the straight through groove A24 at the end. The end of the support rod 23 has a protrusion inside. This protrusion needs to be inserted into and cooperate with the seven equally spaced grooves 26 at the lower end of the through groove B25. Align the protrusion inside the end of the support rod 23 with a certain groove 26 at the lower end of the through groove B25 and press it lightly into the corresponding groove to form an adjustable limiting connection. After the transmission plate 18 and the support rod 23 are hinged, the middle part cooperates with the protrusion at the end of the support rod 23 through the arc-shaped through groove B25, and the end is connected to the pin A19 through the straight through groove A24 to form a left and right movable connection.

[0061] Since the through groove A24 is a straight groove and there is room for left and right movement between it and the pin A19, after installation, it should be confirmed that the transmission plate 18 can move left and right within a certain range to achieve motion compensation and flexible linkage. It should be confirmed that the length of the through groove B25 is 5 times that of the through groove A24 to meet the needs of a larger range of stroke adjustment.

[0062] The operator rotates the turntable 9 according to the process requirements, which drives the transmission plate 18 through the crank 21. The transmission plate 18 hinges in the square through hole in the middle of the slide rod 7. The protrusion at the end of the support rod 23 serves as the fulcrum for the swing of the transmission plate 18. At the same time, since the through groove B25 is arc-shaped and has 7 equally spaced grooves 26, the protrusion at the end of the support rod 23 can be inserted into any of the grooves 26, realizing the quick switching and limiting of the 7 stroke positions. When the stroke needs to be changed, simply pull out the end of the support rod 23 and reposition and lock it with another groove 26 in the through groove B25 of the transmission plate 18 to switch the stroke position. The operation is simple and efficient.

[0063] The crank 21 drives the transmission plate 18 to swing. Through the cooperation between the pin A19 and the straight groove A24 at the end of the transmission plate 18, a certain amount of left and right movement is allowed, which absorbs the slight deviations in the stamping process and ensures smooth movement.

[0064] After the adjustment is completed, the stamping equipment is started. The slide bar 7 drives the slider A12 to move up and down to realize the stamping action. The detection lock, magnetic clamp, vibration damping and other devices work together to ensure stamping safety, reliable clamping and stable equipment.

[0065] Reference Figure 2 A slider B20 is installed in the middle of the support rod 23. The support rod 23 and the slider B20 are connected by a rotating shaft. The support rod 23 and the slider B20 can rotate freely around the rotating shaft. The slider B20 has an internal thread and is connected to the lead screw 22 through the internal thread. The slider B20 is fixedly connected to the rotating shaft and is slidably inserted into the strip groove on the support rod 23 through the rotating shaft.

[0066] Take support rod 23 and clean the central groove to ensure there are no burrs or debris. The groove width should match that of slider B20. Insert slider B20 into the groove of support rod 23, aligning the pivot hole of slider B20 with the pivot hole in the groove of support rod 23. Insert the pivot to achieve a hinged connection between slider B20 and support rod 23, ensuring that slider B20 can rotate freely relative to support rod 23 around the pivot and slide to a limited extent along the groove. Check that the pivot is securely assembled and rotates smoothly, and that slider B20 does not get stuck in the groove.

[0067] Check the internal thread of slider B20 to ensure that the thread is intact and clean. Take lead screw 22, align its external thread with the internal thread of slider B20, and slowly screw it in until it is fully embedded and reaches the predetermined depth. There should be no looseness between lead screw 22 and slider B20. There should be appropriate resistance when rotating to ensure adjustment accuracy. One end of lead screw 22 is fixed to the equipment frame or the range adjustment mechanism so that it can drive the bottom end of support rod 23 to move along through groove B25 when it rotates.

[0068] The entire adjustment mechanism is tested in conjunction with the linkage test to ensure that the slider B20 can move smoothly with the lead screw 22 when the support rod 23 is adjusted, and can rotate freely around the axis. When the operator rotates the lead screw 22, the lead screw 22 is connected to the slider B20 through the internal thread, which converts the rotational motion into the linear movement of the support rod 23 in the through groove B25. By changing the position of the support rod 23, the support point or limit point of the support rod 23 can be precisely adjusted, thereby realizing the fine adjustment of the stroke of the stamping equipment or the gear switching. Example 3

[0069] Based on Example 1, the following is added:

[0070] Reference Figure 4 The sleeve A4 has two symmetrical strip-shaped guide grooves 32 on its inner side. The pin B28, which is located opposite to the guide grooves 32, has a strip-shaped protrusion on its side. The sleeve A4 and the pin B28 are connected and slidably connected by interlocking the guide grooves 32 and the strip-shaped protrusion.

[0071] Reference Figure 4 The sleeve A4 moves up and down along the pin B28, the upper surface of the electromagnet 30 contacts the workpiece 14, and the electromagnet 30 is located on the upper surface of the sleeve A4.

[0072] When the electromagnet 30 is energized, it generates magnetic force to firmly attract the workpiece 14, thus achieving the positioning or clamping function. After the stamping process is completed, the electromagnet 30 is de-energized and loses its magnetic force, allowing the workpiece 14 to be released or removed. After the clamping is released, the drive mechanism moves the sleeve A4 upward to return to the initial position, ready for the next cycle operation. Example 4

[0073] Based on Example 1, the following is added:

[0074] Reference Figure 3 The number of concave plates 6 on a single slide rail 11 is at least two. The rotating shafts of the rotating rod 27 and the protrusion 5 are arranged vertically. The protrusion 5 is rotatably connected to the slider A12 through the rotating shaft. The cross-section of the protrusion 5 is a convex structure, and the cross-section of the concave plate 6 is a concave structure. The protrusion 5 and the concave plate 6 correspond to each other and are fitted with a clearance. The rotating rod 27 controls the protrusion 5 to switch between 0° and 90°.

[0075] Reference Figure 1 The number of guardrail plates 2 is 4 and they are arranged at the four corners of the lower box body 16. The number of bottom bars 33 and sleeves B1 is 12. The bottom bars 33 and sleeves B1 are arranged symmetrically in groups of 6 below the lower box body 16. Each group of bottom bars 33 and sleeves B1 is arranged at equal horizontal and vertical intervals.

[0076] The operator can control the protrusion 5 to switch between 0° and 90° around the axis by rotating the rotary rod 27. When the protrusion 5 is at the 0° position, its convex surface can be embedded in the groove of the concave plate 6 to achieve accurate positioning and limiting. When it is necessary to release the limiting or adjust the position, rotate the rotary rod 27 to 90° to make the protrusion 5 disengage from the groove of the concave plate 6, so that the slider A12 can move. The slider A12 can move smoothly on the slide rail 11. After adjusting to the target position, rotate the rotary rod 27 again to make the protrusion 5 cooperate with the concave plate 6 to achieve rapid positioning.

[0077] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
