Description

Technical Field

[0001] This invention relates to the field of lasers, and more particularly to a quick-switch interface structure for a radio frequency carbon dioxide laser. Background Technology

[0002] Radio frequency (RF) CO2 lasers, with their high power, high stability, and precise energy output characteristics, have been widely used in many key fields such as materials processing, laser cutting, medical equipment, and scientific research. In practical applications, frequent disassembly and reinstallation of lasers have become commonplace to adapt to different processing needs (such as replacing lasers with different power specifications), to cope with equipment failure maintenance, or to achieve rapid changeover in multi-variety, small-batch production lines. The performance of the quick-change interface directly determines the equipment's operating efficiency, processing accuracy consistency, and operational safety.

[0003] In the precision machining of diverse, small-batch electronic components, electronics factories producing mobile phone PCBs, computer chip packages, and other products need to switch between different power lasers (20W, 30W, etc.) to adapt to the cutting requirements of 0.1-0.5mm thin materials. Replacing the existing bolt-fixed structure requires disassembling 8-12 bolts, taking over 30 minutes, while a single order only contains 500-1000 pieces. This changeover time accounts for over 30% of production capacity, creating a bottleneck. Furthermore, a positioning deviation of 0.08mm can easily cause chip pin cutting errors, resulting in a scrap rate as high as 3%. In the scenario of flexible production lines for automotive parts, when car manufacturers produce sheet metal parts for different models, they need to switch between 50W and 80W lasers to adapt to the cutting requirements of 1.2-3mm cold-rolled steel / aluminum alloy. After the existing snap-fit ​​positioning structure is replaced, the repeated positioning deviation exceeds 0.1mm, resulting in excessive gaps between parts, requiring secondary grinding. Moreover, the changeover requires two workers to operate for 20 minutes, and every additional minute of downtime on the production line results in a loss of approximately 200 yuan.

[0004] In the clinical setting of laser treatment in top-tier hospitals, when dermatology departments use radiofrequency carbon dioxide lasers to treat freckles (requiring 20W low power) and repair scars (requiring 50W medium power), patient waiting times are concentrated in the morning (an average of 30-50 people per day). Replacing the laser in the existing structure requires disassembling the medical equipment casing and loosening four fixing bolts, taking 15 minutes. This leads to extended treatment intervals for individual patients, with waiting times exceeding one hour. Furthermore, positioning errors can cause laser spot displacement, damaging normal skin tissue. In multi-parameter laser experiments in research institutions, when university materials science departments study the laser ablation effects on ceramics and polymers, they need to frequently switch between lasers with different pulse widths and powers. Experiments require 8-10 changes per day. The existing bolt-fixed structure is cumbersome to disassemble, with each switch taking 20 minutes, extending the experimental cycle. Multiple disassemblies also reduce positioning accuracy, resulting in poor data repeatability (deviation exceeding 0.1mm), affecting the credibility of research conclusions.

[0005] In customized order scenarios at sheet metal processing plants, small and medium-sized sheet metal factories often face diverse customer needs when undertaking customized orders for furniture hardware, equipment shells, etc. This necessitates switching lasers 5-8 times per week. Existing simple snap-fit ​​structures are prone to insecure positioning, leading to laser misalignment during cutting and resulting in product dimensional deviations. This results in a scrap rate of up to 5%, and each replacement requires 25 minutes of work time from one worker, extending order delivery cycles and increasing customer complaints. In emergency maintenance scenarios on industrial production lines, a sudden malfunction of the RF CO2 laser on a photovoltaic module production line necessitates rapid replacement with a backup machine. Disassembling the existing structure requires over 30 minutes of work from specialized technicians, resulting in a production line downtime loss exceeding 10,000 yuan per hour. Furthermore, the backup machine's positioning is often inaccurate after installation, requiring readjustment of cutting parameters and further extending downtime.

[0006] However, existing laser installation and connection structures have many technical defects, making it difficult to meet the actual needs of the above scenarios: First, insufficient positioning accuracy. Existing structures mostly use simple snap-fit ​​or single-set bolt positioning, lacking precise guidance and dual positioning mechanisms. This results in significant repositioning deviations after laser replacement, especially in precision machining and medical treatment scenarios, where even slight positional shifts can directly affect product yield, treatment safety, or experimental data accuracy. Second, cumbersome operation procedures. To ensure installation stability, existing structures typically use multiple sets of bolts for fixing. Disassembly and installation require tightening each bolt individually, resulting in redundant and time-consuming steps. This severely restricts production line changeover efficiency, medical treatment pace, and experimental progress, failing to meet the demands of fast-paced production and application. Third, lack of safety protection. Existing structures lack a linkage control mechanism between installation status and power supply circuit. Even if the laser is not fully positioned or locked in place, it can still be powered on and started, easily causing the laser to shift or loosen during operation. This not only affects the equipment's lifespan but may also lead to production safety accidents or medical risks. Summary of the Invention

[0007] The present invention proposes a quick-switch interface structure for a radio frequency carbon dioxide laser, which solves the above-mentioned problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A quick-change interface structure for an RF carbon dioxide laser includes a laser, a dovetail locking block fixed to the bottom of the laser by screws, a mounting base slidably mounted below the dovetail locking block, an internal cavity forming a mounting cavity, a cover plate fixed to the top of the mounting cavity by screws, a knob structure horizontally mounted inside the mounting cavity, a lifting plate slidably mounted inside the mounting cavity, the lifting plate being slidably connected to the knob structure, multiple positioning pins for positioning the dovetail locking block mounted on the lifting plate, multiple linearly distributed locking structures mounted on the lifting plate, the locking structures being movably connected to the knob structure, the locking structures being used to fix the dovetail locking block, a terminal block for powering the laser mounted on the left side of the mounting base, and a connecting structure for controlling the on / off state of the terminal block circuit slidably mounted left and right inside the mounting base, the connecting structure being slidably connected to the lifting plate.

[0009] Preferably, the fixing seat has a through hole extending from front to back, and the through hole communicates with the interior of the mounting cavity. The front end of the through hole is threaded to form a threaded hole. The knob structure includes a main shaft that is rotatably mounted in the through hole via a bearing. A rotating screw is threadedly connected to the threaded hole. Both the rotating screw and the thread in the threaded hole are made of Tang thread, which has a good anti-loosening effect. A fixed sleeve is welded to the front end of the main shaft. The fixed sleeve rotates and extends into the through hole. A linear groove is opened at the front end of the fixed sleeve. An insert rod is integrally formed at the tail end of the rotating screw. A linear slider is welded to the outer surface of the insert rod. The insert rod and the linear slider are slidably inserted into the linear groove. A ring is fixed at the front end of the fixed sleeve. The ring is used to limit the insert rod and the linear slider so that they do not fall out of the linear groove.

[0010] Preferably, a circular opening is provided above both the front and rear ends of the lifting plate, and a guide post is slidably inserted into the circular opening. The upper and lower ends of the guide post are respectively fixed to the bottom end of the mounting cavity and the cover plate. The guide post is used to guide the lifting plate to move up and down. A lifting plate is fixed below the lifting plate. A rectangular lifting groove is provided on the lifting plate. A lifting cam is fixed on the main shaft. A lifting roller is fixed on the lifting cam. The lifting roller is rotatably inserted into the lifting groove. The width of the lifting groove is greater than the outer diameter of the lifting roller. In the initial state, when the lifting plate is at the bottom, the lifting roller is located inside and below the lifting groove. There is a certain distance between the top of the lifting groove and the lifting roller. When the lifting cam rotates clockwise under the action of the main shaft, the lifting roller will also rotate clockwise. The lifting roller contacts the top of the lifting chute and pushes the lifting plate upward, thus causing the lifting plate to move upward.

[0011] Preferably, the lower end of the dovetail block has multiple linearly distributed positioning holes, each positioned directly above a plurality of positioning pins. The positioning holes and positioning pins have conical cross-sections. The cover plate has multiple openings, each positioned directly above a positioning pin. When the lifting plate moves upward, it will move the positioning pins upward as a whole, thereby allowing the positioning pins to be inserted into the positioning holes, completing the positioning between the dovetail block and the fixed base. This ensures that the laser above is installed in the designated position, enabling the laser to be quickly and accurately aligned during installation with high repeatability.

[0012] Preferably, the locking structure includes a rotating component rotatably mounted on the lifting plate via a bearing. The bottom end of the rotating component has a lifting port, and a rotating shaft is slidably inserted into the lifting port. The bottom end of the rotating shaft is rotatably connected to the bottom end of the mounting cavity via a bearing seat. A worm gear is mounted on the rotating shaft, and a worm is mounted on the main shaft. The worm gear meshes with the worm, and the transmission ratio between the worm and the worm gear is N / 1, that is, for every one revolution of the worm, the worm gear can rotate several revolutions. The lifting port is provided with a lifting sliding hole, and a lifting slider is welded to the outer ring surface of the rotating shaft. The lifting slider is slidably inserted into the lifting sliding hole. During the lifting plate's up and down movement, the rotating component can move up and down together. During the lifting process, the rotating component always maintains a connection with the rotating shaft. Under the action of the worm gear and worm, the rotating shaft can drive the rotating component to rotate together.

[0013] Preferably, the dovetail block has multiple linearly distributed locking screw holes below it, which are located directly above the rotating part. The upper end of the rotating part has an integrally formed locking part, and the locking part has a threaded section. The threaded section and the threads in the locking screw holes are both Tang threads, which have a good anti-loosening effect. When the lifting plate moves upward by rotating the main shaft, the main shaft will also cause the rotating part and the locking part to rotate through the worm gear, worm and rotating shaft. After the positioning pin positions the dovetail block, it ensures that the locking screw hole is directly above the locking part. Then, as the locking part continues to move upward and rotate, the locking part will be threadedly connected to the locking screw hole.

[0014] Preferably, the left side surface of the fixing seat has a sliding hole that communicates with the interior of the mounting cavity. The communication structure includes a pressure plate that is slidably inserted into the sliding hole. The pressure plate has a rectangular opening, and a guide block is slidably inserted into the rectangular opening. The guide block is fixed to the fixing seat. A tension spring is placed in the rectangular opening, and the two ends of the tension spring are fixed to the pressure plate and the guide block, respectively. The tension spring causes the pressure plate to always have a tendency to move towards the inside of the mounting cavity.

[0015] Preferably, the portion below one end of the pressure plate inside the mounting cavity is cut off to form a pressure slope, and the portion above the left side of the lifting plate is cut off to form a compression slope. The compression slope is directly below the pressure slope, and the two slopes are the same. As the lifting plate moves upward, the pressure slope will come into contact with the compression slope, thereby pushing the pressure plate to move away from the lifting plate, that is, the pressure plate moves to the left. When the lifting plate moves downward, and the compression slope disengages from the pressure slope, the pressure plate moves towards the side closer to the lifting plate under the action of the tension spring.

[0016] Preferably, the terminal block includes a wiring port fixed to the side of the mounting base and a compression switch. The wiring port and the compression switch are electrically connected by a wire, and the wiring port is electrically connected to the laser by a line. The switch of the compression switch faces the sliding hole, and the pressure plate will contact the switch when it is pressed outward. When the lifting plate rises to its highest point, that is, after the laser is positioned and locked, the pressure plate will completely press the switch, thus making the wiring port open. Only then can the laser be powered on and run. If the laser is not installed precisely, it cannot start. This avoids the laser from shifting during use if it is misaligned, thus improving accuracy.

[0017] The beneficial effects of this invention are: 1. This invention achieves dual positioning during laser installation by using a dovetail locking block and a sliding guide mechanism with a fixed base, combined with a tapered positioning pin and positioning hole. The tapered structure can automatically correct installation deviations, ensuring precise alignment between the positioning pin and the positioning hole. This allows the laser to remain in the designated position after each installation, significantly improving repeatability and effectively avoiding processing or experimental errors caused by positional offset.

[0018] 2. The knob structure integrates lifting drive, positioning trigger and locking control functions. Only by rotating the rotary screw can multiple actions such as lifting the lifting plate, inserting the positioning pin and locking the locking part be completed simultaneously. There is no need to operate multiple parts step by step. When disassembling, simply rotate the knob in the opposite direction to unlock quickly. The entire quick change process is simple to operate and streamlined, which greatly shortens the time for laser replacement or maintenance and improves equipment operation efficiency.

[0019] 3. Through the linkage design of the connecting structure and the lifting plate, the pressure plate will only squeeze the squeeze switch when the lifting plate rises to the highest point, that is, when the laser is fully positioned and locked in place, so that the wiring terminal is connected to the power supply. If the laser is not installed in place or is not locked securely, the power supply circuit will always be in the disconnected state, which avoids the deviation, damage or safety accidents caused by the equipment being started by mistake from the root, and improves the safety protection level of the equipment.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Reference Figure 1 - Figure 8 A quick-change interface structure for a radio frequency carbon dioxide laser includes a laser 1. A dovetail block 2 is fixed to the bottom of the laser 1 by screws. A fixing seat 3 is slidably installed below the dovetail block 2. The fixing seat 3 has an internal cavity forming a mounting cavity 32. A cover plate 31 is fixed to the top of the mounting cavity 32 by screws. A knob structure 5 is horizontally installed inside the mounting cavity 32. A lifting plate 6 is slidably installed inside the mounting cavity 32 and is slidably connected to the knob structure 5. Multiple positioning pins 7 for positioning the dovetail block 2 are installed on the lifting plate 6. Multiple linearly distributed locking structures 8 are installed on the lifting plate 6 and are movably connected to the knob structure 5. The locking structures 8 are used to fix the dovetail block 2. A terminal block 4 for powering the laser 1 is installed on the left side of the fixing seat 3. A connecting structure 9 for controlling the circuit on / off of the terminal block 4 is slidably installed inside the fixing seat 3 and is slidably connected to the lifting plate 6.

[0024] Reference Figure 3 - Figure 6 The fixed seat 3 has a through hole running through it from front to back, and the through hole is connected to the interior of the mounting cavity 32. The front end of the through hole is threaded to form a threaded hole. The knob structure 5 includes a main shaft 51 that is rotatably mounted in the through hole through a bearing. A rotating screw 53 is threadedly connected in the threaded hole. The rotating screw 53 and the thread in the threaded hole are both made of Tang thread, which has a good anti-loosening effect. A fixed sleeve 52 is welded to the front end of the main shaft 51. The fixed sleeve 52 rotates and extends into the through hole. A linear slide groove 521 is opened at the front end of the fixed sleeve 52. The tail end of the rotating screw 53 is integrally formed with a plug rod. A linear slider 531 is welded to the outer surface of the plug rod. The plug rod and the linear slider 531 are slidably inserted into the linear slide groove 521. A ring is fixed at the front end of the fixed sleeve 52. The ring is used to limit the plug rod and the linear slider 531 so that they will not fall out of the linear slide groove 521. Rotating the rotating screw 53 will drive the fixed sleeve 52 and the main shaft 51 to rotate together. When the rotating screw 53 rotates clockwise or counterclockwise, it will move in a straight line along the linear slide groove 521 inward or outward. At this time, the linear slider 531 and the plug rod will move along the linear slide groove 521, thereby ensuring the connection between the rotating screw 53 and the fixed sleeve 52. The rotating screw 53 can always drive the fixed sleeve 52 to rotate.

[0025] Reference Figure 3 - Figure 6 The lifting plate 6 has a round opening at the top of both the front and rear ends. A guide post 62 is slidably inserted into the round opening. The upper and lower ends of the guide post 62 are fixed to the bottom of the mounting cavity 32 and the cover plate 31, respectively. The guide post 62 is used to guide the lifting plate 6 to move up and down. A lifting plate 61 is fixed below the lifting plate 6. A rectangular lifting groove 611 is provided on the lifting plate 61. A lifting cam 54 is fixed on the main shaft 51. A lifting roller 541 is fixed on the lifting cam 54. The lifting roller 541 is rotatably inserted into the lifting groove 611. The width of the lifting groove 611 is greater than the outer diameter of the lifting roller 541. In the initial state, when the lifting plate 6 is at the bottom, the lifting roller 541 is located inside and below the lifting groove 611. There is a certain gap between the top of the lifting groove 611 and the lifting roller 541. When the lifting cam 54 rotates clockwise under the action of the main shaft 51, the lifting roller 541 will rotate clockwise along with it. The lifting roller 541 contacts the top of the lifting slide 611 and pushes the lifting plate 61 to move upward, thereby causing the lifting plate 6 to move upward. When the lifting plate 6 is at its highest position, the lifting roller 541 is in contact with the top of the lifting chute 611. At this time, there is a certain distance between the lifting roller 541 and the bottom of the lifting chute 611. Rotating the main shaft 51 counterclockwise causes the lifting cam 54 and the lifting roller 541 to rotate counterclockwise together. After the main shaft 51 causes the lifting cam 54 and the lifting roller 541 to rotate counterclockwise by a certain angle, the lifting roller 541 will contact the bottom of the lifting chute 611 and push the lifting plate 6 to move downward, so that the lifting plate 6 returns to its original position.

[0026] Reference Figure 4 The dovetail block 2 has multiple linearly distributed positioning holes 22 at its lower end. The positioning holes 22 are located directly above the positioning pins 7. The positioning holes 22 and the positioning pins 7 have conical cross-sections. The cover plate 31 has multiple openings, which are located directly above the positioning pins 7. When the lifting plate 6 moves upward, it will drive the positioning pins 7 to move upward as a whole, so that the positioning pins 7 are inserted into the positioning holes 22, completing the positioning between the dovetail block 2 and the fixed base 3. This keeps the laser 1 installed in the designated position, so that the laser 1 can be quickly and accurately aligned during installation, with high repeatability.

[0027] Reference Figure 5 , Figure 6 The locking structure 8 includes a rotating component 81 rotatably mounted on the lifting plate 6 via a bearing. The bottom end of the rotating component 81 has a lifting port, and a rotating shaft 82 is slidably inserted into the lifting port. The bottom end of the rotating shaft 82 is connected to the inside of the mounting cavity 32 via a bearing seat. The bottom end is rotatably connected, a worm gear 83 is installed on the rotating shaft 82, and a worm 55 is installed on the main shaft 51. The worm gear 83 meshes with the worm 55 to drive it. The transmission ratio between the worm 55 and the worm gear 83 is N / 1, that is, the worm gear 83 can rotate several times for the worm 55 to rotate one revolution. A lifting slide hole 812 is provided in the lifting port, and a lifting slider 821 is welded to the outer surface of the rotating shaft 82. The lifting slider 821 is slidably inserted into the lifting slide hole 812. During the up and down movement of the lifting plate 6, the rotating component 81 can move up and down together. During the lifting process, the rotating component 81 always maintains the connection with the rotating shaft 82. Under the action of the worm gear 83 and the worm 55, the rotating shaft 82 can drive the rotating component 81 to rotate together.

[0028] Reference Figure 6 Multiple linearly distributed locking screw holes 21 are provided below the dovetail block 2. The locking screw holes 21 are located directly above the rotating part 81. The upper end of the rotating part 81 is integrally formed with a locking part 811. The locking part 811 is threaded to form a threaded section. The threaded section and the thread in the locking screw hole 21 are both made of Tang thread, which has a good anti-loosening effect. When the lifting plate 6 moves upward by rotating the main shaft 51, the main shaft 51 will also rotate the rotating part 81 and the locking part 811 through the worm gear 83, worm 55 and rotating shaft 82. After the positioning pin 7 positions the dovetail block 2, it ensures that the locking screw hole 21 is directly above the locking part 811. Then, as the locking part 811 continues to move upward and rotate, the locking part 811 will be threadedly connected to the locking screw hole 21 to ensure the connection between the locking structure 8 and the dovetail block 2. When unlocking, the main shaft 51 is rotated in the opposite direction to make it rotate counterclockwise. Since the lifting plate 6 is at the top, the lifting roller 541 is located inside the lifting slide 611. There is a certain gap between the bottom end of the lifting slide 611 and the lifting roller 541 to avoid interference with the rotation of the main shaft 51. At this time, the rotating part 81 will also rotate in the opposite direction under the action of the rotating shaft 82, so that the locking part 811 is disengaged from the locking screw hole 21.

[0029] Reference Figure 7 , Figure 8The left side surface of the fixed base 3 has a sliding hole that communicates with the interior of the mounting cavity 32. The communication structure 9 includes a pressure plate 91 that is slidably inserted into the sliding hole. The pressure plate 91 has a rectangular opening, and a guide block 92 is slidably inserted into the rectangular opening. The guide block 92 is fixed to the fixed base 3. A tension spring 93 is placed in the rectangular opening. The two ends of the tension spring 93 are fixed to the pressure plate 91 and the guide block 92, respectively. The tension spring 93 makes the pressure plate 91 always tend to move towards the inner end of the mounting cavity 32.

[0030] The pressure plate 91 has a portion cut off below one end inside the mounting cavity 32 to form a pressure slope 94. The upper left side of the lifting plate 6 has a portion cut off to form a pressing slope 63. The pressing slope 63 is directly below the pressure slope 94, and the two have the same slope. As the lifting plate 6 moves upward, the pressure slope 94 will come into contact with the pressing slope 63, thereby pushing the pressure plate 91 to move away from the lifting plate 6, that is, the pressure plate 91 moves to the left. When the lifting plate 6 moves downward, the pressing slope 63 disengages from the pressure slope 94, and the pressure plate 91 moves towards the side closer to the lifting plate 6 under the action of the tension spring 93.

[0031] The terminal block 4 includes a wiring port 42 fixed to the side of the mounting base 3 and a compression switch 41. The wiring port 42 and the compression switch 41 are electrically connected by wires. The wiring port 42 is electrically connected to the laser 1 through a line. The switch of the compression switch 41 faces the sliding hole. When the pressure plate 91 is pressed outward, it will contact the switch. When the lifting plate 6 rises to the highest point, that is, after the laser 1 is positioned and locked, the pressure plate 91 will completely abut against the switch of the compression switch 41, so that the compression switch is open, thereby making the wiring port 42 open. Only then can the laser 1 be powered on and run. If the laser 1 is not accurately installed in place, the laser 1 cannot be started, which avoids the laser 1 from shifting during use when it is misinstalled, thus improving accuracy.

[0032] Working principle: In the initial state, the lifting plate 6 is at the bottom. At this time, the positioning pin 7 and the locking structure 8 are both in the mounting cavity 32, and the pressure plate 91 in the connecting structure 9 is close to the lifting plate 6 under the action of the tension spring 93.

[0033] In actual use, a dovetail clip 2 is fixed to the bottom of each laser 1 by screws. When installing the laser 1, the dovetail clip 2 under the laser 1 is directly slid into the dovetail groove on the fixed base 3. Then, the rotating screw 53 is rotated clockwise. When the rotating screw 53 is rotated clockwise, the rotating screw 53 will move in a straight line along the straight slide groove 521 in the threaded hole. At this time, the straight slider 531 and the plug rod will move along the straight slide groove 521, thereby ensuring the connection between the rotating screw 53 and the fixed sleeve 52. By rotating the rotating screw 53, the fixed sleeve 52 and the main shaft 51 can be rotated together. When the main shaft 51 rotates, the lifting cam 54 and the lifting roller 541 located on the main shaft 51 will also rotate clockwise. At the same time, the rotating shaft 82 will also rotate with the main shaft 51 under the action of the worm gear 83 and the worm 55. After the lifting roller 541 is offset clockwise by a certain angle, it will contact the top of the lifting slide 611 and push the lifting plate 61 to move upward, thereby causing the lifting plate 6 to move upward. That is, the lifting plate 6 moves upward. At the same time, the rotating part 81 and the locking part 811 located above the lifting plate 6 will also move upward and rotate clockwise. After the lifting plate 6 rises to a certain height, the positioning pin 7 on the lifting plate 6 will contact the positioning hole 22 below the dovetail block 2, thereby completing the positioning of the dovetail block 2. Then the lifting plate 6 continues to move upward, the positioning pin 7 is inserted into the positioning hole 22 and continues to move upward, while the locking part 811, which rotates and rises at the same time, will contact and screw into the locking screw hole 21. The locking part 811 will be threadedly connected to the locking screw hole 21 to ensure the connection between the locking structure 8 and the dovetail block 2. At the same time, when the lifting plate 6 rises to the highest point, that is, after the laser 1 is positioned and locked, the pressure plate 91 will completely squeeze the switch, so that the wiring port 42 is in the open state. Only then can the laser 1 be connected to the power supply and run. If the laser 1 is not accurately installed in place, the laser 1 cannot be started, thus avoiding the offset during use when the laser 1 is misinstalled, and improving accuracy.

[0034] When disassembly is required, rotate the screw 53 counterclockwise, causing the main shaft 51, worm gear 83, worm 55, and lifting cam 54 to rotate counterclockwise. Since the lifting plate 6 is at the top at this time, and the lifting roller 541 is in contact with the top of the lifting slide 611, there is a certain distance between the lifting roller 541 and the bottom of the lifting slide 611. When the main shaft 51 rotates counterclockwise, the worm gear 83 and worm 55 first cause the locking part 811 to rotate in the opposite direction, causing the locking part 811 to exit the locking screw hole 21. Then, after the main shaft 51 causes the lifting cam 54 and lifting roller 541 to rotate counterclockwise by a certain angle, the lifting roller 541 will contact the bottom of the lifting slide 611 and push the lifting plate 6 to move downward, so that the lifting plate 6 returns to its original position. The positioning pin 7 and locking structure 8 disengage from the dovetail block 2. At this time, the laser 1 and dovetail block 2 can be directly pulled out and a new laser 1 can be replaced.
