Description

Technical Field

[0001] This invention relates to the field of connection and locking technology, specifically to a quick-release connection and locking mechanism and an airborne module for unmanned aerial vehicles. Background Technology

[0002] With the rapid development of drone technology, the role of onboard modules connected to drones in fields such as power grid inspection and fault clearing is becoming increasingly prominent. Currently, the connection and locking mechanisms between drones and onboard modules mostly adopt traditional single mechanical structures such as bolt fastening and snap-fit ​​splicing. When using multiple sets of bolts for fastening, special tools such as wrenches are required to operate one by one, making the assembly process time-consuming and laborious, significantly extending the preparation time for operation; disassembly also requires repetitive and tedious tool operations, resulting in low efficiency in the maintenance and replacement of onboard modules. Although some snap-fit ​​structures do not require tools, they lack intuitive assembly status indicators, making it difficult for operators to quickly determine whether the connection is in place, requiring repeated checks and confirmations, increasing the complexity of operation. To address this, we have introduced a quick-release connection and locking mechanism and a drone onboard module. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-release connection locking mechanism and an onboard module for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick-release connection locking mechanism, including a connection frame seat installed on the bottom of a drone, wherein a sliding seat is slidably connected inside the connection frame seat; The sliding seat is equipped with front and rear abutment ejection indicator components. The middle groove in the middle of the sliding seat is connected to a lifting abutment component by a return spring. The end of the lifting abutment component is equipped with a tensioning component. The front end of the middle groove is also equipped with a hydraulic cylinder. After the sliding seat slides into the grooves on both sides of the connecting frame seat, the ejector indicator assembly moves forward relative to the sliding seat. The piston on the ejector indicator assembly presses the oil in the hydraulic cylinder into the end of the lifting abutment assembly through the hose, causing the tensioning assembly to move upward relative to the lifting abutment assembly until the top of the tensioning assembly is in close contact with the top wall inside the connecting frame seat, thus completing the installation of the sliding seat and the connecting frame seat. The sliding seat has an inner groove with a backing plate. The light rod pin assembly at the inner end of the backing plate extends into the middle groove and is movably connected to the middle of the lifting backing assembly. The side of the connecting frame seat is also provided with a pressing assembly. After the pressing component is pressed, it pushes the abutment plate, causing the guide pin component to move the lifting abutment component downward, thereby causing the top of the tensioning component to disengage from the top wall inside the connecting frame. Then, under the elastic force of the abutment pop-out indicator component, the sliding seat pops out towards the front of the connecting frame until the sliding seat is removed.

[0005] Preferably, the top of the connecting frame is installed on the bottom of the drone with a first bolt. The bottom of the drone is provided with a plug-in groove and a power socket in the plug-in groove. The upper rear part of the connecting frame is provided with a plug-in seat that is inserted into the plug-in groove. The plug-in seat is provided with a conductive post, and the top of the conductive post is inserted into the corresponding power socket.

[0006] Preferably, the upper rear part of the sliding base is provided with an arc-shaped protruding elastic conductive sheet, and the bottom of the conductive post is in close contact with the top of the corresponding arc-shaped protruding elastic conductive sheet.

[0007] Preferably, the upper and lower ends of the connecting frame are respectively provided with an upper slot and a lower slot, and the upper end of the sliding seat is provided with a front protrusion and a rear protrusion, which are slidably connected to the upper slot. The slide groove is equipped with two sets of gears, one in front and one behind, which mesh with the teeth on the side of the sliding seat.

[0008] The arc-shaped protruding elastic conductive sheet is disposed in the clearance groove on the rear protrusion seat.

[0009] Preferably, the front part of the chute is provided with a ramp surface, and the front end of the sliding seat is provided with a sealing seat, which is used to engage with the front end of the chute; The front end of the sliding seat is provided with an marking groove extending to the front end of the sealing seat; The abutting pop-out sign assembly includes an abutting rod, an abutting plate fixed after the rear end of the abutting rod extends out of the sliding seat, and a sign plate fixed after the front end of the abutting rod extends into the sign slot; The rear end of the sliding seat is provided with a spring receiving hole for installing the abutment spring, and the abutment spring is sleeved on the outside of the abutment rod, with the rear end of the abutment spring fixed to the front end of the abutment plate; The piston is fixed to the abutment rod and is located inside the hydraulic cylinder.

[0010] Preferably, the lifting and abutting assembly includes a U-shaped seat fixed to the top of the return spring and a lifting seat fixed at the corner of the U-shaped seat by a connecting arm; The sliding seat is also provided with side grooves symmetrically distributed on both sides of the middle groove. The side grooves are connected to the middle groove by vertical grooves. The end of the connecting arm passes through the corresponding vertical groove, and the lifting seat slides into the corresponding side groove. The tensioning assembly includes a rubber bladder installed in the bladder mounting groove at the upper end of the lifting seat, a tensioning plate connected to the upper part of the lifting seat by a vertical light rod, and an anti-slip protrusion at the upper end of the tensioning plate. The hose is connected to the bottom of the front end of the hydraulic cylinder and the bottom of the U-shaped seat, so that the hydraulic cylinder is connected to the rubber bladder through the hose and the channel inside the lifting and abutting assembly.

[0011] Preferably, the guide rod pin assembly includes two sets of horizontal guide rods connected to the inner side of the abutment plate, a pin connecting the end of the horizontal guide rod to the middle groove, and two sets of ear plates fixed to the side of the U-shaped seat. The pin slides into the inclined groove on the corresponding ear plate.

[0012] Preferably, the pressing assembly includes a buffer cylinder fixed to the side of the slide groove, a sliding plate slidably connected inside the buffer cylinder, a pressing rod disposed in the middle of the sliding plate, and a buffer spring sleeved on the pressing rod; The buffer spring is disposed inside the buffer cylinder, and the outer end of the buffer spring is fixed to the inner end of the sliding plate. The outer end of the pressing rod extends out of the sliding groove and is fixed with a pressing plate, while the inner end of the pressing rod extends out of the buffer cylinder.

[0013] In addition, to achieve the above objectives, the present invention also provides an airborne module for unmanned aerial vehicles, including the aforementioned quick-release connection locking mechanism.

[0014] Compared with the prior art, the beneficial effects of the present invention are: During the sliding connection between the sliding base and the connecting frame base of this invention, the abutting pop-out marking component moves synchronously. The operator can quickly confirm whether the assembly is in place by observing the marking plate at the front end of the abutting pop-out marking component, avoiding repeated checks and improving assembly efficiency.

[0015] This invention features a synchronous action between the ejector component and the hydraulically driven tensioning component, ensuring a tight fit between the tensioning component and the top wall of the connecting frame, thus achieving locking and preventing loosening due to vibration. Compared to traditional rigid locking, the smoothness of hydraulic transmission can adapt to minor errors in the top wall, improving the fit.

[0016] During disassembly, this invention only requires pressing the pressing plate on the side of the connecting frame seat. The pressing component pushes the abutment plate, which in turn moves the lifting abutment component downward via the smooth rod pin assembly, quickly releasing the tension. Subsequently, the abutment spring releases its elasticity, pushing the sliding seat to pop out automatically. The entire disassembly process requires no tools, shortens the operation time, and improves efficiency compared to traditional bolt disassembly. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Please see Figures 1-25 The present invention provides a technical solution: A quick-release connection locking mechanism includes a connection frame seat 2 mounted on the bottom of a drone 1; The top of the connecting frame 2 is installed on the bottom of the drone 1 with the first bolt 11. The bottom of the drone 1 is provided with a plug groove 101 and a power socket 102 in the plug groove 101. The upper rear part of the connecting frame 2 is provided with a plug seat 206 that is inserted into the plug groove 101. The plug seat 206 is provided with a conductive post 207, and the top of the conductive post 207 is inserted into the corresponding power socket 102.

[0021] First, the connecting frame 2 and the drone 1 are fixed to form the drone module. The top of the connecting frame 2 is installed on the bottom of the drone 1 by the first bolt 11. At this time, the plug 206 at the upper rear of the connecting frame 2 is inserted into the plug groove 101 at the bottom of the drone 1. The top of the conductive post 207 on the plug 206 is precisely inserted into the corresponding power socket 102, laying the foundation for subsequent circuit connection.

[0022] The sliding joint 14 is fixed to the power grid laser obstacle clearing device 4 by the second bolt 18 to form an obstacle clearing module; the arc-shaped protruding elastic conductive sheet 1403 is electrically connected to the laser emitter in the power grid laser obstacle clearing device 4.

[0023] During installation or disassembly, only the sliding joint 14 and the connecting frame 2 need to be installed or disassembled, without disassembling the entire machine structure, which greatly improves maintenance efficiency.

[0024] A sliding seat 14 is slidably connected inside the connecting frame 2; The sliding base 14 is equipped with a front and rear abutment pop-out indicator assembly. The middle groove 1405 in the middle of the sliding base 14 is connected to a lifting abutment assembly through a return spring 17. The end of the lifting abutment assembly is equipped with a tensioning assembly. The front end of the middle groove 1405 is also equipped with a hydraulic cylinder 32. The top of the intermediate groove 1405 is provided with an end cap 13 that is flush with the upper surface of the sliding seat 14; After the sliding seat 14 slides into the sliding groove 202 inside the inner side of the connecting frame seat 2 on both sides, the ejector marking component moves forward relative to the sliding seat 14. The piston 27 on the ejector marking component presses the oil in the hydraulic cylinder 32 into the end of the lifting abutment component through the hose 33, so that the tensioning component moves upward relative to the lifting abutment component until the top of the tensioning component is in close contact with the top wall inside the connecting frame seat 2, thus completing the installation of the sliding seat 14 and the connecting frame seat 2. A backing plate 12 is provided in the inner groove 1408 on the side of the sliding seat 14. The light rod pin assembly at the inner end of the backing plate 12 extends into the middle groove 1405 and is movably connected to the middle of the lifting backing assembly. A pressing assembly is also provided on the side of the connecting frame seat 2. After the pressing component is pressed, the pressing component pushes the abutment plate 12, causing the light rod pin component to move the lifting abutment component downward, thereby causing the top of the tensioning component to disengage from the top wall inside the connecting frame 2. Subsequently, under the elastic force of the abutment pop-out marking component, the sliding seat 14 pops out in front of the connecting frame 2 until the sliding seat 14 is removed.

[0025] The upper rear part of the sliding base 14 is provided with an arc-shaped protruding elastic conductive sheet 1403, and the bottom of the conductive post 207 is in close contact with the top of the corresponding arc-shaped protruding elastic conductive sheet 1403.

[0026] The elastic fit design of the conductive post 207 and the arc-shaped protruding elastic conductive sheet 1403, compared with rigid contact, can compensate for assembly errors through the deformation of the arc-shaped sheet, ensuring stable circuit contact; at the same time, the elastic structure can absorb the small displacement caused by vibration, avoid poor contact, and ensure the reliability of the power supply to the laser emitter of the power grid laser obstacle clearing device 4.

[0027] The upper and lower ends of the connecting frame 2 are respectively provided with an upper slot 201 and a lower slot 203. The upper end of the sliding seat 14 is provided with a front protrusion 1401 and a rear protrusion 1402, which are slidably connected to the upper slot 201. The front part of the sliding groove 202 is provided with a ramp surface 208.

[0028] The sliding seat 14 uses a multi-directional guiding structure that allows the two sides to slide into the slide groove 202, the front protrusion 1401 and the rear protrusion 1402 to connect to the upper slot 201. Combined with the sloping surface 208 at the front of the slide groove 202, the sliding seat 14 can be quickly aligned and inserted, reducing assembly difficulty.

[0029] The slide groove 202 is equipped with two sets of gears 204, one in front and one behind, which mesh with the teeth 16 on the side of the sliding seat 14. The meshing of the gears 204 in the slide groove 202 with the teeth 16 on the side of the sliding seat 14 converts the sliding friction into gear transmission, which reduces assembly resistance, limits the vertical movement of the sliding seat 14, and improves the lateral positioning accuracy.

[0030] An arc-shaped protruding elastic conductive sheet 1403 is disposed in a clearance groove on the rear protrusion seat 1402.

[0031] A sealing seat 6 is provided at the front end of the sliding seat 14, and the sealing seat 6 is used to be engaged with the front end of the slide groove 202; Sealing and protection design: The sealing seat 6 at the front end of the sliding seat 14 is inserted into the front end of the slide groove 202, which can effectively prevent dust and moisture from entering the slide groove 202 and the interior of the intermediate groove 1405, protect moving parts such as gear 204 and spring, and extend the service life of the mechanism; the integrated design of each hydraulic pipeline and connection part reduces the risk of leakage and improves the sealing performance of the mechanism.

[0032] The front end of the sliding seat 14 is provided with an marking groove 1404 extending to the front end of the sealing seat 6; The abutting pop-out sign assembly includes an abutting rod 26, an abutting plate 29 fixed after the rear end of the abutting rod 26 extends out of the sliding seat 14, and a sign plate 5 fixed after the front end of the abutting rod 26 extends into the sign groove 1404. The abutment rod 26 extends through the upper center of the U-shaped seat 22; The rear end of the sliding seat 14 is provided with a spring receiving hole 1409 for installing the abutment spring 28, and the abutment spring 28 is sleeved on the outside of the abutment rod 26, and the rear end of the abutment spring 28 is fixed to the front end of the abutment plate 29. The piston 27 is fixed on the abutment rod 26 and is located inside the hydraulic cylinder 32.

[0033] Linkage between the ejector component and the hydraulic cylinder 32: The piston 27 and the label plate 5 are integrated on the abutment rod 26. When the sliding seat 14 slides in, the dual functions of "hydraulic drive" and "label assembly" are realized simultaneously.

[0034] The piston 27 directly utilizes the assembly force of the sliding seat 14 to squeeze the oil, eliminating the need for an additional power source and simplifying the structure. The position of the indicator plate 5 within the indicator groove 1404 visually reflects the assembly progress, improving operational convenience. Simultaneously, the abutment spring 28 provides reset power for disassembly and maintains the pressure of the piston 27 after assembly, ensuring stable tension in the rubber bladder 30 and preventing loosening of the locking mechanism.

[0035] The lifting and abutting assembly includes a U-shaped seat 22 fixed to the top of the return spring 17 and a lifting seat 25 fixed at the corner of the U-shaped seat 22 by a connecting arm 19; The return spring 17 has a dual function: it not only provides the return power for the U-shaped seat 22, so that the lifting and abutting components return to their initial position after disassembly, but also assists the tensioning components in maintaining stability during assembly through pre-tightening force, forming a dual guarantee of "hydraulic active locking + spring passive pressure holding", which improves the reliability of the mechanism under complex working conditions.

[0036] The sliding seat 14 is also provided with side grooves 1406 symmetrically distributed on both sides of the middle groove 1405. The side grooves 1406 are connected to the middle groove 1405 by a vertical groove 1407. The end of the connecting arm 19 passes through the corresponding vertical groove 1407, and the lifting seat 25 slides in the corresponding side groove 1406. The tensioning assembly includes a rubber bag 30 disposed in a bag mounting groove 31 at the upper end of the lifting seat 25, a tensioning plate 15 connected above the lifting seat 25 by a vertical light rod 152, and an anti-slip protrusion 151 disposed at the upper end of the tensioning plate 15. The vertical guide rod 152 is inserted into the corresponding guide rod hole on the lifting seat 25; The hose 33 is connected to the bottom of the front end of the hydraulic cylinder 32 and the bottom of the U-shaped seat 22, so that the hydraulic cylinder 32 is connected to the rubber bag 30 through the hose 33 and the channel inside the lifting and abutting component.

[0037] Hydraulic drive of the lifting and tensioning components: Hydraulic fluid is transmitted to the rubber bladder 30 through the hose 33. The smoothness of hydraulic transmission causes the tensioning plate 15 to move upward evenly under force. In conjunction with the anti-slip protrusion 151 at the upper end of the tensioning plate 15, the friction with the top wall of the connecting frame 2 is increased, preventing loosening caused by vibration. Compared with purely mechanical locking, hydraulic drive can adapt to small errors in the top wall, improving the locking fit. The elastic properties of the rubber bladder 30 also have a buffering effect, absorbing the vibration and impact during the flight of the UAV 1 and protecting the onboard modules.

[0038] The lifting and abutting assembly features a multi-slot constraint: the connecting arm 19 passes through the vertical slot 1407, and the lifting seat 25 slides into the side slot 1406, forming a multi-slot constraint structure consisting of a central slot 1405, a side slot 1406, and a vertical slot 1407. This design allows the lifting seat 25 to move only in the vertical direction, avoiding tension misalignment caused by horizontal deviation, ensuring that the force direction of the tensioning plate 15 is precisely aligned with the top wall, and improving locking reliability.

[0039] The guide rod pin assembly includes two sets of horizontal guide rods 20 connected to the inner side of the abutment plate 12, a pin 21 connected after the end of the horizontal guide rod 20 extends into the intermediate groove 1405, and two sets of ear plates 23 fixed to the side of the U-shaped seat 22. The pin 21 slides into the inclined groove 24 on the corresponding ear plate 23.

[0040] The inclined groove 24 of the guide rod pin assembly transmits power: the horizontal guide rod 20 is connected to the pin 21, and the pin 21 slides in the inclined groove 24 of the ear plate 23, efficiently converting the horizontal force of the pressing component into the vertical force of the lifting seat 25. The guiding effect of the inclined groove 24 ensures that the force transmission has no idle stroke, and the pressing action directly triggers the locking release, with a rapid response; the symmetrical design of the two sets of horizontal guide rods 20 and ear plates 23 ensures that the lifting seat 25 is subjected to balanced forces, avoiding jamming caused by unilateral offset.

[0041] The pressing assembly includes a buffer cylinder 7 fixed to the side of the slide groove 202, a sliding plate 9 slidably connected inside the buffer cylinder 7, a pressing rod 8 provided in the middle of the sliding plate 9, and a buffer spring 10 sleeved on the pressing rod 8. The buffer spring 10 is disposed inside the buffer cylinder 7, and the outer end of the buffer spring 10 is fixed to the inner end of the sliding plate 9. The outer end of the pressing rod 8 extends out of the slide groove 202 and is fixed with the pressing plate 3. The inner end of the pressing rod 8 extends out of the buffer cylinder 7.

[0042] The buffer spring 10 inside the buffer cylinder 7 works in conjunction with the sliding plate 9 to provide damping during pressing, preventing excessive force from causing structural damage, and to achieve automatic reset after disassembly, simplifying operation; the enlarged design of the pressing plate 3 improves pressing comfort and meets ergonomic requirements.

[0043] Furthermore, to achieve the above objectives, the present invention also provides an airborne module for a drone, including a quick-release connection locking mechanism. The airborne module is an electric grid laser obstacle clearing device 4. The sliding base 14 is fixed to the top of the electric grid laser obstacle clearing device 4 by the second bolt 18 inside the intermediate groove 1405, and then the sliding base 14 is assembled with the connecting frame 2 at the bottom of the drone 1.

[0044] The quick-release connection locking mechanism uses a core drive method of "mechanical-hydraulic linkage" combined with structural designs such as multi-dimensional guidance, elastic buffer, and modular integration. It not only realizes the convenient operation of "one-click disassembly and automatic locking" between the obstacle clearing module and the drone module, but also ensures the stability and reliability of the connection through multiple protection structures. At the same time, it takes into account the stability of circuit connection and the vibration resistance of the mechanism, and is fully adapted to the usage requirements of drone onboard modules.

[0045] When the drone module takes off, driving the obstacle removal module, the laser emitter of the obstacle removal module emits a laser beam at the foreign object on the power grid at an appropriate location. Under the continuous irradiation of the laser beam, the temperature of the target point of the foreign object rises sharply within a few seconds to tens of seconds, far exceeding its melting point (for plastics, it can reach hundreds of degrees Celsius), thereby achieving the removal of foreign objects from the power grid.

[0046] Specifically, when using it: Assembly of the obstacle clearing module and the drone module: Align the sliding base 14 of the obstacle clearing module with the connecting frame 2 of the UAV module, so that the two sides of the sliding base 14 slide into the sliding groove 202 on the inner side of the connecting frame 2. At the same time, the front protrusion 1401 and the rear protrusion 1402 at the upper end of the sliding base 14 slide into the upper slot 201 in the middle of the upper end of the connecting frame 2. Initial positioning is achieved through multi-part guidance and cooperation.

[0047] The sliding seat 14 slides within the slide groove 202 until the abutment plate 29 contacts the rear wall of the slide groove 202, compressing the abutment spring 28. The abutment ejection marker assembly moves forward relative to the sliding seat 14, causing the piston 27 fixed on the abutment rod 26 to move synchronously within the hydraulic cylinder 32.

[0048] The squeezing action of piston 27 forces the oil in hydraulic cylinder 32 through hose 33 into the channel inside lifting abutment component, and finally into the rubber bladder 30 of tensioning component.

[0049] During this process, the abutment spring 28 is compressed to store the reset force, while the marking plate 5 at the front end of the abutment rod 26 moves synchronously in the marking groove 1404. The assembly progress can be intuitively judged by the position of the marking plate 5.

[0050] The tensioning assembly expands to achieve locking and fixation: After the oil is injected into the rubber bag 30, the rubber bag 30 expands and bulges in the bag mounting groove 31, pushing the tensioning plate 15 connected by the vertical light rod 152 to move upward until the anti-slip protrusion 151 at the upper end of the tensioning plate 15 is in close contact with the top wall inside the connecting frame seat 2.

[0051] At this time, the sliding seat 14 is fixed by the pressure of the tension plate 15 and the top wall, while the gear 204 in the slide groove 202 meshes with the teeth 16 on the side of the sliding seat 14, further restricting the lateral displacement and completing the locking of the sliding seat 14 and the connecting frame seat 2.

[0052] Circuit connection completes assembly loop: While being tensioned and fixed, the bottom of the conductive post 207 on the connecting frame 2 is tightly fitted with the top of the arc-shaped protruding elastic conductive sheet 1403 in the clearance groove of the rear protruding seat 1402 of the sliding seat 14. The elastic deformation of the arc-shaped protruding elastic conductive sheet 1403 ensures the reliability of the conductive contact, realizing the circuit connection between the UAV 1 and the power grid laser obstacle clearing device 4, and the entire assembly process is completed.

[0053] Disassembly of the obstacle clearing module and the drone module: The disassembly process uses the pressing component as the trigger point to release the tension through mechanical transmission, and the sliding seat 14 automatically pops out using spring force. The operation is convenient and efficient. The specific process is as follows: Pressing triggers mechanical linkage: Pressing the pressing plate 3 on the side of the connecting frame 2 inward causes the pressing rod 8 to move into the buffer cylinder 7. The pressing rod 8 pushes the sliding plate 9 to compress the buffer spring 10, and the buffer spring 10 begins to store elastic force.

[0054] The inner end of the pressing rod 8 acts directly on the abutment plate 12 in the inner groove 1408 on the side of the sliding seat 14, pushing the abutment plate 12 to move towards the middle groove 1405.

[0055] The lifting and abutting assembly moves down to release tension: When the abutting plate 12 moves, the horizontal light rod 20 on its inner side drives the pin 21 at the end to move synchronously. The pin 21 slides in the inclined groove 24 of the ear plate 23. Through the guiding effect of the inclined groove 24, the horizontal force is converted into a vertical downward force, which pulls the U-shaped seat 22 to compress the return spring 17 and move it downward.

[0056] The U-shaped seat 22 drives the lifting seat 25 to move down along the side groove 1406 via the connecting arm 19. The rubber bag 30 on the lifting seat 25 moves down accordingly, and the tensioning plate 15 disengages from the inner top wall of the connecting frame seat 2, thus releasing the locking state.

[0057] Spring force drives the sliding seat to pop out: After the tension is released, the compressed abutment spring 28 in the spring receiving hole 1409 releases its elastic force, causing the abutment plate 29 to move backward relative to the sliding seat 14, and the sliding seat 14 as a whole pops out towards the front of the connecting frame 2.

[0058] During this process, the piston 27 on the abutment rod 26 moves backward relative to the hydraulic cylinder 32, generating negative pressure inside the hydraulic cylinder 32. The oil in the rubber bladder 30 flows back to the hydraulic cylinder 32 through the hose 33, preparing for the next assembly.

[0059] Disassembly and resetting completed: After the sliding base 14 pops out, the obstacle clearing module can be directly removed to complete the disassembly.

[0060] After the pressing plate 3 is released, the buffer spring 10 pushes the sliding plate 9 and the pressing rod 8 to reset. The abutment plate 12 returns to its initial position under the reaction force of the lifting abutment component reset spring 17, and the entire mechanism returns to the assembly state.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
