Description

Technical Field

[0001] This invention relates to the field of shaft parts processing technology, and in particular to a propulsion and positioning mechanism and method for long shaft parts. Background Technology

[0002] Shaft parts are one of the typical parts frequently encountered in hardware accessories. For some extra-long and extra-heavy long shaft workpieces, rotation is required during processing. Existing propulsion and positioning devices focus on propulsion and positioning. However, most devices cannot accurately and stably achieve the requirement of maintaining rotation after propulsion and positioning. Moreover, it is not convenient to make quantitative propulsion each time during propulsion and positioning, and each drive device is required for propulsion and fixing, resulting in high cost and complicated operation.

[0003] To address the aforementioned problems, this invention proposes a propulsion and positioning mechanism and method for long-shaft parts. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing propulsion and positioning devices, which focus on propulsion and positioning. After propulsion and positioning, the device must be able to rotate, which most devices cannot achieve accurately and stably. Moreover, during the propulsion and positioning process, it is not convenient to make quantitative propulsion each time, and each propulsion and fixing requires a driving device, resulting in high cost and complicated operation. Therefore, this invention proposes a propulsion and positioning mechanism and method for long shaft parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A long-shaft part propulsion and positioning mechanism and method thereof, comprising a part positioning mechanism, wherein a propulsion mechanism is mounted on the part positioning mechanism;

[0007] The part positioning mechanism includes a base, on which a pre-positioning component is connected, and a workpiece is inserted through the pre-positioning component;

Two clamping components are connected above the transmission component and are located on both sides of the workpiece. The clamping components correspond to two inclined plates, which are fixedly connected to the support frames. The two inclined plates are slidably connected to a movable plate in a positioning distance adjustment component. The positioning distance adjustment component is mounted on the support frame.

[0010] The other two drive wheels are each fixedly connected to a second rotating shaft, which is rotatably connected to the support frame.

[0011] Preferably, the positioning distance adjustment component includes a screw, one end of which is fixedly connected to a handwheel, the screw is rotatably connected to a fixed block via a bearing, and the fixed block is fixedly connected to a support frame;

[0012] A threaded cylinder is threadedly connected to the screw, and the threaded cylinder is embedded in the movable plate.

[0013] Preferably, the upper and lower sides of the movable plate are fixedly connected with slide bars, the slide bars are slidably connected in the slide opening, and the slide opening is opened on the inclined plate;

[0014] A slider is fixedly connected to one side of the movable plate, and a pointer is fixedly connected to one side of the slider. The slider is slidably connected in the guide opening, which is opened on the support frame. Scale lines are provided on the support frame and on both the upper and lower sides of the guide opening. The pointer corresponds to the scale lines.

[0015] Preferably, the clamping assembly includes a fixing plate, which is fixedly connected above the belt. Three sliding sleeves are installed on the fixing plate, and a sliding rod is slidably connected inside the sliding sleeve. One end of the sliding rod is fixedly connected to a pulley. The three pulleys correspond to two inclined plates and a movable plate, respectively. A first spring is fixedly connected between the pulley and the sliding sleeve.

[0016] The other end of each of the three slide rods is fixedly connected to the same fixed frame. Both ends of the fixed frame are rotatably connected to two third rotating shafts via two bearings. A rubber wheel is fixedly connected to each third rotating shaft, and one of the third rotating shafts is fixedly connected to the second bevel gear.

[0017] Preferably, the air pressure regulating component includes a connecting plate, which is fixedly connected to one of the movable plates. A cylindrical tube is fixedly connected to the top of the connecting plate. One end of the cylindrical tube is provided with a one-way valve and a thin tube. A second piston rod is provided inside the cylindrical tube. The second piston rod extends out of the cylindrical tube and is fixedly connected to the tube body. The tube body is connected to the cylindrical tube through an air inlet hose. A first piston rod is provided inside the tube body. The first piston rod extends out of the tube body. A second spring is fixedly connected between the first piston rod and the inner wall of the tube body.

[0018] Preferably, the transmission assembly includes a frame, which is fixedly connected to the first piston rod, and a second motor is fixedly installed in the frame, with the output shaft of the second motor fixedly connected to the first bevel gear.

[0019] Preferably, the prepositioning component includes two support plates, with a rectangular sleeve installed through the two support plates. A bushing is fixedly connected above the support plates, and multiple balls are rotatably installed inside the bushing.

[0020] Preferably, a sliding plate is slidably connected inside the rectangular sleeve, a movable plate is fixedly connected to one end of the sliding plate, a support column is fixedly connected above the movable plate, and an annular ring is rotatably mounted on the support column through a bearing. The workpiece passes through the annular ring and two bushings, and the workpiece is fixed to the annular ring by fixing bolts.

[0021] A method for using a long-shaft part propulsion and positioning mechanism includes the following steps:

[0022] S1. When pushing the workpiece, the workpiece passes through the two bushings in sequence and enters the ring. Then, the workpiece is locked by the fixing bolt. Then, the first motor drives the first rotating shaft to rotate, which makes the transmission wheel move. The transmission wheel drives the belt to move, and the belt controls the fixed plate to move, so that the pulley contacts the inclined plate. At this time, the inclined surface of the inclined plate squeezes the pulley to move, which makes the slide rod drive the fixed frame to move. The fixed frame drives the rubber wheel to move, and the rubber wheels on both sides get closer to each other to clamp the workpiece.

[0023] S2. Then, the transmission component continues to drive the clamping component to move, so that the workpiece follows the movement. When the second bevel tooth meshes with the first bevel tooth, the second motor drives the first bevel tooth and the second bevel tooth to drive the transmission, so that the third rotating shaft drives the rubber wheel to rotate, and the workpiece follows to turn. This process meets the needs of workpiece processing.

[0024] S3. When the workpiece continues to be pushed forward, the second bevel tooth squeezes the first bevel tooth to move, and the second motor drives the first piston rod to move through the frame. The gas inside the cylinder is discharged into the cylindrical cylinder through the air inlet hose. The second piston rod is controlled by air pressure to move the cylinder upward, so that the first bevel tooth and the second bevel tooth move away from each other, allowing the clamping assembly to pass smoothly. Then, the second spring drives the first piston rod to reset and extract the gas inside the cylindrical cylinder. Because the diameter of the thin tube is small, the second piston rod moves slowly, so that the cylinder completes the slow reset.

[0025] Compared with the prior art, the present invention provides a propulsion and positioning mechanism and method for long shaft parts, which has the following beneficial effects:

[0026] 1. The long shaft part pushing and positioning mechanism and method thereof, through the first motor driving the first rotating shaft to rotate, the first rotating shaft drives the transmission wheel, and under the cooperation of the transmission wheel and belt transmission, the clamping assembly performs translational movement. When the pulley contacts the inclined surface of the inclined plate and continues to push, the inclined surface of the inclined plate squeezes the pulley and drives the sliding rod to move. Then the fixed frame drives the rubber wheel to move, so that the rubber wheels on both sides can automatically clamp and position the workpiece, improving the convenience of operation. Moreover, after clamping, the purpose of automatic pushing and feeding of the workpiece can be realized. When the first bevel tooth and the second bevel tooth mesh, the second motor drives the first bevel tooth and the second bevel tooth to drive the transmission, so that the rubber wheel drives the workpiece to rotate automatically, thereby satisfying the workpiece processing operation.

[0027] 2. The long shaft part propulsion and positioning mechanism and method, by operating the handwheel to drive the screw to rotate, the screw to drive the threaded cylinder to move, so that the threaded cylinder can drive the movable plate to move in translation, thus the misalignment distance between the movable plate and the inclined plate can be adjusted, so that the upper and lower pulleys roll on the plane of the inclined plate, and then the middle pulley can roll smoothly on the movable plate. Due to the extended misalignment distance between the movable plate and the inclined plate, after the upper and lower pulleys disengage from the inclined plate, the middle pulley can be supported on the movable plate, so that the position of the fixed frame can continue to be maintained, and the rubber wheel can continue to clamp the workpiece, thereby realizing the adjustment of the workpiece feeding distance and meeting the purpose of quantitative propulsion.

[0028] 3. The long shaft part pushing and positioning mechanism and method thereof, through the first motor driving the first rotating shaft to rotate, so that the transmission wheel and belt drive can drive the clamping component to move. When the pulley contacts the inclined surface of the inclined plate, the pulley is squeezed by the inclined surface of the inclined plate and drives the sliding rod to move. The first spring deforms synchronously, so that the fixed frame drives the rubber wheel to clamp and fix the workpiece. At this time, the workpiece can be fed. When the pulley separates from the movable plate and the inclined plate, the first spring resets and drives the sliding rod to reset, so that the rubber wheel separates from the workpiece, completing the purpose of removing the workpiece. This process can meet the purpose of clamping, pushing and removing the workpiece, meet the needs of high-efficiency processing, and at the same time reduce the addition of equipment, thereby reducing costs.

Detailed Implementation

[0041] 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.

[0042] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0043] Example 1: Refer to Figure 1-4 and Figure 8-11 A long-shaft type part propulsion and positioning mechanism includes a part positioning mechanism 100, on which a propulsion mechanism 200 is mounted;

[0044] The part positioning mechanism 100 includes a base 101, on which a pre-positioning component 102 is connected. The pre-positioning component 102 includes two support plates 1022, and a rectangular sleeve 1021 is installed through the two support plates 1022. A bushing 1023 is fixedly connected above the support plates 1022. Multiple balls 1024 are rotatably mounted inside the bushing 1023. The bushing 1023 can support the workpiece 103, maintaining its stability. While supporting the workpiece 103, the balls 1024 also assist the workpiece 103 in rotating smoothly, reducing its rotational resistance and allowing it to rotate smoothly for processing. A sliding plate 1025 is slidably connected inside the rectangular sleeve 1021, allowing the moving plate 1026 to move smoothly. One end of the sliding plate 1025 is fixedly connected to a moving plate 1026. The movable plate 1026 is equipped with a movable wheel at its bottom, which can roll to not only maintain stable support for the movable plate 1026, but also to make the movable plate 1026 move stably. A support column 1027 is fixedly connected to the top of the movable plate 1026. The support column 1027 is rotatably mounted with an annular ring 1028 through a bearing. The annular ring 1028 can rotate through the bearing, so that the workpiece 103 can rotate smoothly, avoiding the problem of the fixed bolt 1029 locking the workpiece 103 and preventing it from rotating. The workpiece 103 passes through the annular ring 1028 and two bushings 1023, and the workpiece 103 is fixed to the annular ring 1028 by the fixed bolt 1029. By operating the fixed bolt 1029, one end of the workpiece 103 can be locked in the annular ring 1028, thereby preventing the workpiece 103 from tilting due to its length. The workpiece 103 passes through the prepositioning component 102.

[0045] The propulsion mechanism 200 includes two support frames 201, which are fixedly connected to the top of the base 101. A transmission assembly 202 is connected between the two support frames 201. The transmission assembly 202 includes two sets of drive wheels 2023, with two drive wheels 2023 in each set, and they are connected by a belt 2022. The two drive wheels 2023 are driven by the belt 2022, which allows the belt 2022 to move and drive the clamping assembly 205 to perform translational operations. A first rotating shaft 2024 is fixedly installed between the two drive wheels 2023. The first rotating shaft 2024 is rotatably connected to the two support frames 201 through two bearings and can connect the two drive wheels 2023. The two belts 2022 can synchronously drive the two clamping assemblies 205 to move, and the first rotating shaft 2024 can also rotate smoothly through bearings. One end of the first rotating shaft 2024 is fixedly connected to the output shaft of the first motor 2021, which is fixedly mounted on the support frame 201. Two second rotating shafts 2025 are fixedly connected to the other two transmission wheels 2023. The second rotating shafts 2025 are rotatably connected to the support frame 201 and can maintain stable rotation through bearings, thus ensuring stable rotation of the transmission wheels 2023. Two clamping assemblies 205 are connected above the transmission assembly 202. Each clamping assembly 205 includes a fixing plate 2055, which is fixedly connected above the belt 2022. Three sliding sleeves 2056 are installed on the 5th plate. A sliding rod 2057 is slidably connected inside the sliding sleeve 2056. The sliding sleeve 2056 guides the sliding rod 2057, allowing it to move smoothly and stably. A pulley 2059 is fixedly connected to one end of the sliding rod 2057. The pulley 2059 can roll, reducing the movement resistance between the pulley 2059 and the inclined plate 204 and improving the smoothness of operation. The three pulleys 2059 correspond to the two inclined plates 204 and the movable plate 2035, respectively. The inclined surface at the end of the inclined plate 204 can squeeze the passing pulleys 2059, so that the pulleys 2059 can control the movement of the sliding rod 2057 and the fixed frame 2051, allowing the rubber wheel 2052 to clamp the workpiece 103. The pulleys 2059 and the sliding sleeves 2056... A first spring 2058 is fixedly connected between the three slide rods 2057 and 6. The restoring force of the first spring 2058 can drive the slide rod 2057 to return to its original position, causing the fixing frame 2051 to move the rubber wheel 2052 away from the workpiece 103, thereby removing the positioning of the workpiece 103. The other ends of the three slide rods 2057 are all fixedly connected to the same fixing frame 2051. Both ends of the fixing frame 2051 are rotatably connected to two third rotating shafts 2053 through two bearings. The third rotating shafts 2053 can maintain smooth rotation through the bearings, so that the third rotating shafts 2053 can drive the rubber wheel 2052 to rotate. The rubber wheel 2052 is fixedly connected to the third rotating shaft 2053. The rubber wheel 2052 can clamp the workpiece 103, and the rubber wheel 2052 will generate a certain deformation through compression.This increases the contact area with the workpiece 103 and improves anti-slip properties, allowing the rubber wheel 2052 to smoothly rotate the workpiece 103. One of the third rotating shafts 2053 is fixedly connected to the second bevel gear 2054. Two clamping assemblies 205 are located on both sides of the workpiece 103, corresponding to two inclined plates 204. The two inclined plates 204 are fixedly connected to the support frame 201, and are slidably connected to a movable plate 2035 in the positioning distance adjustment assembly 203. The positioning distance adjustment assembly 203 is mounted on the support frame 201. A pneumatic pressure regulating assembly 206 is connected above one of the movable plates 2035. The pneumatic pressure regulating assembly 206 includes a connecting plate 2065, which is connected to one of the movable plates 2035. 35. A cylindrical cylinder 2061 is fixedly connected to the top of the connecting plate 2065. One end of the cylindrical cylinder 2061 is equipped with a one-way valve 2063 and a thin tube 2062. The cylindrical cylinder 2061 remains sealed, thus maintaining gas storage. The one-way valve 2063 allows for one-way exhaust, while the exhaust through the thin tube 2062 accelerates the exhaust and the movement of the second piston rod 2064. The smaller diameter of the thin tube 2062 allows for slow air intake into the cylindrical cylinder 2061, thus maintaining the slow movement of the second piston rod 2064. This allows the second piston rod 2064 to slowly reset the cylinder 2067, preventing the drive assembly from rapidly resetting and obstructing the second bevel gear 2054 again. The second piston rod 2064 is located inside the cylindrical cylinder 2061. A piston rod 2064 extends out of the cylindrical tube 2061 and is fixedly connected to the tube body 2067. The tube body 2067 is connected to the cylindrical tube 2061 via an air inlet hose 2066. The air inlet hose 2066 can maintain air supply and is movable, allowing the tube body 2067 to move smoothly. A first piston rod 2068 is installed inside the tube body 2067, extending out of the tube body 2067. A second spring 2069 is fixedly connected between the first piston rod 2068 and the inner wall of the tube body 2067. The restoring force of the second spring 2069 can drive the first piston rod 2068 to return to its original position, causing the gas inside the cylindrical tube 2061 to be extracted. This allows the second piston rod 2064 to smoothly drive the tube body 2067 and the drive assembly. Upon reset, one end of the air pressure regulating component 206 is connected to a transmission component 207. The transmission component 207 includes a frame 2071, which is fixedly connected to the first piston rod 2068. A second motor 2072 is fixedly installed in the frame 2071, which secures the second motor 2072 and ensures its stability. The second motor 2072 drives the first bevel gear 2073 and the second bevel gear 2054, thereby driving the third rotating shaft 2053 and the rubber wheel 2052 to rotate, allowing the workpiece 103 to rotate. The output shaft of the second motor 2072 is fixedly connected to the first bevel gear 2073. The first bevel gear 2073 in the transmission component 207 corresponds to the second bevel gear 2054 in the clamping component 205.

[0046] In this embodiment: the first motor 2021 drives the first rotating shaft 2024 to rotate, which in turn drives the transmission wheel 2023. Under the transmission cooperation of the transmission wheel 2023 and the belt 2022, the clamping assembly 205 performs translational movement. When the pulley 2059 contacts the inclined surface of the inclined plate 204 and continues to advance, the inclined surface of the inclined plate 204 squeezes the pulley 2059, causing the sliding rod 2057 to move. Then, the fixed frame 2051 drives the rubber wheel 2052 to move, so that the rubber wheels 2052 on both sides can automatically clamp and position the workpiece 103, improving the convenience of operation. Moreover, after clamping, the workpiece 103 can be automatically fed. When the first bevel tooth 2073 meshes with the second bevel tooth 2054, the second motor 2072 drives the first bevel tooth 2073 and the second bevel tooth 2054 to drive the transmission, thereby causing the rubber wheel 2052 to drive the workpiece 103 to rotate automatically, thus satisfying the processing operation of the workpiece 103.

[0047] Example 2: Refer to Figure 5-7 A positioning mechanism for a long-shaft part includes a positioning distance adjustment component 203. The positioning distance adjustment component 203 includes a screw 2031, one end of which is fixedly connected to a handwheel 2033. The handwheel 2033 can be used as a force application point for convenient operation. The screw 2031 is rotatably connected to a fixed block 2032 via a bearing. The screw 2031 can be smoothly mounted and maintained in rotation via the bearing. The fixed block 2032 is fixedly connected to a support frame 201. A threaded cylinder 2034 is threadedly connected to the screw 2031. The position of a movable plate 2035 can be adjusted through the threaded transmission between the screw 2031 and the threaded cylinder 2034. The threaded cylinder 2034 is embedded in the movable plate 2035. Sliding strips 2038 are fixedly connected to both the upper and lower sides of the movable plate 2035. The slider 2038 is slidably connected in the slide opening 210. The slider 2038 can slide smoothly through the slide opening 210, thereby allowing the movable plate 2035 to move smoothly. The slide opening 210 is opened on the inclined plate 204. A slider 2037 is fixedly connected to one side of the movable plate 2035. A pointer 2036 is fixedly connected to one side of the slider 2037. The slider 2037 is slidably connected in the guide opening 208. The slider 2037 can slide stably through the guide opening 208, thereby allowing the movable plate 2035 to move stably. The guide opening 208 is opened on the support frame 201. Scale lines 209 are provided on the support frame 201 and on both the upper and lower sides of the guide opening 208. The pointer 2036 corresponds to the scale line 209. By indicating the scale on the corresponding scale line 209, the movement distance of the movable plate 2035 can be accurately determined.

[0048] In this embodiment: the screw 2031 is rotated by operating the handwheel 2033, and the screw 2031 drives the threaded cylinder 2034 to move, so that the threaded cylinder 2034 can drive the movable plate 2035 to move in translation. This makes the misalignment distance between the movable plate 2035 and the inclined plate 204 adjustable, so that the upper and lower pulleys 2059 roll on the plane of the inclined plate 204. Then, the middle pulley 2059 can roll smoothly on the movable plate 2035. Since the misalignment distance between the movable plate 2035 and the inclined plate 204 is extended, after the upper and lower pulleys 2059 are separated from the inclined plate 204, the middle pulley 2059 can be supported on the movable plate 2035, so that the position of the fixed frame 2051 can continue to be maintained, and the rubber wheel 2052 continues to clamp the workpiece 103. This allows the feeding distance of the workpiece 103 to be adjusted to meet the purpose of quantitative feeding.

[0049] Example 3: Reference Figure 4 and Figure 8 A long-shaft part propulsion and positioning mechanism includes a transmission component 202. The transmission component 202 includes two sets of transmission wheels 2023, each set of transmission wheels 2023 having two wheels, which are connected by a belt 2022. The same first rotating shaft 2024 is fixedly installed between the two transmission wheels 2023. The first rotating shaft 2024 is rotatably connected to two support frames 201 through two bearings. One end of the first rotating shaft 2024 is fixedly connected to the output shaft of a first motor 2021. The first motor 2021 is fixedly installed on the support frame 201. A second rotating shaft 2025 is fixedly connected to each of the other two transmission wheels 2023. The second rotating shaft 2025 is rotatably connected to the support frame 201.

[0050] The clamping assembly 205 includes a fixed plate 2055, which is fixedly connected above the belt 2022. Three sliding sleeves 2056 are installed on the fixed plate 2055. Sliding rods 2057 are slidably connected inside the sliding sleeves 2056. One end of the sliding rod 2057 is fixedly connected to a pulley 2059. The three pulleys 2059 correspond to the two inclined plates 204 and the movable plate 2035, respectively. A first spring 2058 is fixedly connected between the pulley 2059 and the sliding sleeve 2056. The other end of each of the three sliding rods 2057 is fixedly connected to the same fixed frame 2051. Both ends of the fixed frame 2051 are rotatably connected to two third rotating shafts 2053 through two bearings. A rubber wheel 2052 is fixedly connected to the third rotating shaft 2053. One of the third rotating shafts 2053 is fixedly connected to a second bevel tooth 2054.

[0051] In this embodiment: the first motor 2021 drives the first rotating shaft 2024 to rotate, so that the transmission wheel 2023, in conjunction with the belt 2022, can drive the clamping assembly 205 to move. When the pulley 2059 contacts the inclined surface of the inclined plate 204, the pulley 2059 is squeezed by the inclined surface of the inclined plate 204, which can drive the sliding rod 2057 to move. The first spring 2058 deforms synchronously, so that the fixing frame 2051 drives the rubber wheel 2052 to clamp and fix the workpiece 103. At this time, the workpiece 103 can be fed. When the pulley 2059 separates from the movable plate 2035 and the inclined plate 204, the first spring 2058 resets and drives the sliding rod 2057 to reset, so that the rubber wheel 2052 separates from the workpiece 103, completing the purpose of removing the workpiece 103. This process can meet the purpose of clamping, pushing and removing the workpiece 103, meet the needs of high-efficiency processing, and at the same time reduce the addition of equipment, thereby reducing costs.

[0052] A method for using a long-shaft part propulsion and positioning mechanism includes the following steps:

[0053] S1. When pushing the workpiece 103, the workpiece 103 passes through the two bushings 1023 in sequence and enters the annular ring 1028. At this time, the workpiece 103 is locked by the fixing bolt 1029. Then, the first motor 2021 is controlled to drive the first rotating shaft 2024 to rotate, causing the transmission wheel 2023 to move. The transmission wheel 2023 drives the belt 2022 to move. The belt 2022 controls the fixed plate 2055 to move, causing the pulley 2059 to contact the inclined plate 204. At this time, the inclined surface of the inclined plate 204 squeezes the pulley 2059 to move, causing the slide rod 2057 to drive the fixed frame 2051 to move. The fixed frame 2051 drives the rubber wheel 2052 to move. The rubber wheels 2052 on both sides are relatively close to clamp the workpiece 103.

[0054] S2. Then, the transmission component 202 continues to drive the clamping component 205 to move, so that the workpiece 103 follows the movement. When the second bevel tooth 2054 meshes with the first bevel tooth 2073, the second motor 2072 drives the first bevel tooth 2073 and the second bevel tooth 2054 to drive the third rotating shaft 2053 to drive the rubber wheel 2052 to rotate. Then the workpiece 103 follows the direction of rotation. This process meets the processing requirements of the workpiece 103.

[0055] S3. When the workpiece 103 continues to be advanced, the second bevel tooth 2054 squeezes the first bevel tooth 2073 to move, causing the second motor 2072 to drive the first piston rod 2068 to move through the frame 2071. This causes the gas inside the cylinder 2067 to be discharged into the cylindrical cylinder 2061 through the air inlet hose 2066. The second piston rod 2064 is controlled by air pressure to move, causing the cylinder 2067 to move upward, so that the first bevel tooth 2073 and the second bevel tooth 2054 move away from each other, allowing the clamping assembly 205 to pass smoothly. Then, the second spring 2069 drives the first piston rod 2068 to reset and extract the gas inside the cylindrical cylinder 2061. Because the diameter of the thin tube 2062 is small, the second piston rod 2064 moves slowly, thus causing the cylinder 2067 to slowly reset.

[0056] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
