For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] like Figures 1 to 8As shown, the present invention provides an automatic chemical agent brushing device for screw-connected parts, which is used to brush the chemical agent on the external thread of the screw-connected parts. Specifically, the chemical agent can be a lubricant, a lubricating oil, or a fastener. Among them, the lubricant and the lubricating oil are used to reduce friction and improve sealing; the fastener is used to improve the anti-loosening effect and sealing effect of the screw-connected parts.

[0054] The screw-connector size range that can be coated by the automatic chemical agent coating device for screw-connector in the present invention is M5-M8. In this embodiment, the screw-connector can be a screw or a bolt. The coating range of the screw-connector can be the entire threaded section of the screw-connector, or it can be limited to the threaded section of the screw-connector. In this embodiment, the coating of the fastener on the threaded section of the screw-connector is used as an example for description.

[0055] The automatic chemical agent brushing device for screw-connected parts of the present invention comprises a base 1, a clamping module 4 and a brushing module 2. The clamping module 4 is mounted on the base 1, and is used to clamp the screw-connected parts. The brushing module 2 is mounted on the base 1, and is used to brush the threaded section of the screw-connected parts. The clamping module 4 and / or the brushing module 2 are movably arranged on the base 1, and the clamping module 4 and the brushing module 2 are relatively movable along the axial direction of the screw-connected parts.

[0056] When the threaded section of the screw-in component needs to be coated, the clamping module 4 first clamps the screw-in component to fix the screw-in component, and the clamping module 4 and the coating module 2 can generate relative movement along the axial direction of the screw-in component to coat the fastener in the thread of the bolt. The coating module 2 realizes automatic coating of the screw-in fastener, and the coated fastener can flow along the rotation direction of the thread, thereby improving the uniformity of coating.

[0057] In this embodiment, the clamping module 4 can move or the painting module 2 can move, that is, the painting module 2 moves back and forth along the axial direction of the screw connection during the painting process, and the clamping module 4 is fixed; or the clamping module 4 moves back and forth along the axial direction of the screw connection during the painting process, and the painting module 2 is fixed. Alternatively, the clamping module 4 and the painting module 2 can move simultaneously.

[0058] Specifically, the base 1 is a structure with an opening at the top, and a storage slot 11 is provided inside, and the storage slot 11 is connected to the opening at the top. When the screw connection needs to be stored, the screw connection can be directly placed into the storage slot 11 through the opening. Through the provision of the storage slot 11, the automatic chemical agent brushing device for screw connection has the function of storing screw connections. In this embodiment, the shape of the base 1 can be selected. Preferably, the base 1 is a rectangular parallelepiped or a cube, which can provide a large storage capacity while being easy to take and put.

[0059] In this embodiment, the clamping module 4 and the coating module 2 are both arranged on the top of the base 1, located at the opening of the base 1. When the clamping module 4 takes out the threaded part from the storage groove 11, the coating module 2 can directly apply the fastener on the threaded section of the threaded part.

[0060] In this embodiment, when the clamping module 4 clamps the screw-connector, the screw-connector is in a vertical state, that is, the screw-connector head is located at the top and the screw-connector part with threads is located at the bottom. During the painting process, the screw-connector rod with threads is exposed to the outside, and the entire threaded section of the screw-connector is painted by moving the painting module 2 up and down.

[0061] In this embodiment, two painting modules 2 are provided, and both painting modules 2 are provided on the base 1 and are both located at the top of the base 1. The two painting modules 2 are respectively located on both sides of the clamping module 4 and are opposite to each other. When painting the screw-connected parts, the two painting modules 2 move up and down at the same time to apply the fastener to the screw-connected parts. By providing two painting modules 2, the painting effect can be further improved, and the two painting modules 2 can cover all the threaded sections of the screw-connected parts to ensure the uniformity of the painting effect.

[0062] In this embodiment, the painting module 2 is movably arranged on the base 1. The painting end of the painting module 2 swings back and forth along the axial direction of the screw-connector; or the painting end of the painting module 2 moves back and forth along the axial direction of the screw-connector. The painting of the screw-connector is achieved by moving or swinging the painting module 2. During the movement or swinging process, the painting section can cover the entire thread section, and the painting efficiency is high.

[0063] Specifically, the painting module 2 includes a painting rod 21 and a brush head 2101. The painting rod 21 is movably arranged on the base 1. The painting rod 21 and the brush head 2101 are detachably connected or fixedly connected. Preferably, the painting rod 21 and the brush head 2101 are detachably connected to facilitate the rapid replacement of the brush head 2101. During painting, there is a fastener at the brush head 2101, and the brush head 2101 contacts the threaded section of the screw-connected part, and the fastener on the brush head 2101 is brushed on the threaded section of the screw-connected part.

[0064] In this embodiment, in order to ensure the brushing effect of the screw connection, the brush rod 21 can achieve the brushing effect by sliding up and down. Specifically, a mounting groove 2002 is provided in the base 1, and the end of the brush module 2 away from the brushing end is movably arranged in the mounting groove 2002 along the axial direction of the screw connection, which is used to provide the brushing end of the brush module 2 with space to move along the axial direction of the screw connection. When brushing, the brush rod 21 moves back and forth between the bottom wall and the top wall of the mounting groove 2002, thereby achieving the brushing effect.

[0065] In this embodiment, the up and down sliding of the painting rod 21 can be realized by a driving mechanism, such as a cylinder, a linear motor, an electric push rod, etc. Take the cylinder as an example: the cylinder body of the cylinder is installed on the base 1, the output end of the cylinder is located in the mounting groove 2002, and the painting rod 21 is connected to the output end of the cylinder. The up and down movement of the painting rod 21 is realized by the extension and contraction of the cylinder.

[0066] In this embodiment, in order to realize reciprocating motion, it can be realized through the cooperation of sensors and controllers. According to the displacement requirements of the painting rod 21, the appropriate stroke of the painting rod 21 is determined. Sensors are respectively installed at the upper limit position and the lower limit position of the installation groove 2002. The position of the painting rod 21 is detected by the sensor, and the painting rod 21 can reciprocate between the upper limit position and the lower limit position. Specifically, the sensor can be an infrared sensor or a beam sensor.

[0067] In this embodiment, the reciprocating sliding of the painting rod 21 can also be achieved by the cooperation of the driving motor, the slide rail and the slider. In this embodiment, this structure will not be described in detail.

[0068] In this embodiment, the brush rod 21 can also be used to paint the screw-connected part by swinging up and down. By swinging the brush rod 21 up and down, a larger painting area can be covered, thereby significantly improving the painting efficiency. Through continuous and uniform swinging action, the fastener can be evenly distributed on the surface of the screw-connected part, avoiding the problem of local excessive thickness or excessive thinness.

[0069] In this embodiment, the painting module 2 further includes a driving mechanism 24, which can form a curved path through its own structure, and the painting rod 21 performs reciprocating swinging motion along the curved path. When painting, the driving mechanism 24 is started, and the driving mechanism 24 forms a specific curved path using its own structure, and the painting rod 21 achieves a swinging effect along the specific curved path formed by the driving mechanism 24.

[0070] In this embodiment, the driving mechanism 24 includes a driving member and a swinging member, the driving member is mounted on the base 1, and the swinging member 24 is driven to rotate by the driving member. The rotation of the swinging member drives the painting rod 21 to swing.

[0071] Specifically, the driving member is mounted on the inner wall of the base 1, and the swinging member is connected to the output shaft of the driving member. The output shaft of the driving member rotates, driving the swinging member to rotate. Since the swinging member has a curved profile, the painting rod 21, as a follower, will move along the predetermined trajectory of the swinging member, thus achieving a swinging effect.

[0072] In this embodiment, the driving member can be a motor, or a combination of a motor and a speed reduction mechanism. The swinging member can be a cam or an eccentric wheel.

[0073] In this embodiment, in order to improve the stability of the painting rod 21 when it swings, a swing bracket 23 is provided in the installation groove 2002. There are two swing brackets 23. The two swing brackets 23 are respectively located on both sides of the installation groove 2002. The two swing brackets 23 are respectively rotatably connected to the side walls of the corresponding installation groove 2002.

[0074] In this embodiment, in order to facilitate the installation of the painting rod 21 and ensure the synchronization of rotation, a connecting piece is provided between the two swing brackets 23, and the painting rod 21 is installed on the connecting piece, and a groove is formed on each swing bracket 23. During installation, the connecting piece is inserted between the two swing brackets 23 through the groove on the swing bracket 23, and the installation is convenient and quick.

[0075] In this embodiment, the connecting member is a plate-like structural member, and the swinging member contacts the connecting member, and the swinging member rotates to drive the connecting member to swing, thereby realizing the swing of the painting rod 21. Since the contact area of ​​the connecting member is larger, the transmission with the swinging member is more stable, and the painting effect is more uniform.

[0076] In this embodiment, the swing bracket 23 is rotatably connected to the inner wall of the mounting groove 2002 via a rotating shaft. A sliding groove is provided on the inner wall of the mounting groove 2002, and the rotating shaft slides in the sliding groove. Through the cooperation of the rotating shaft and the sliding groove, the connecting piece realizes a sliding connection, that is, the sliding design of the brushing rod 21 and the base 1 can adjust the distance between the brush heads 2101 on both sides, which can meet the brushing requirements of screw-connected parts with different diameters, thereby improving the practicality and adaptability of the device.

[0077] In this embodiment, a plurality of brush rods 21 are provided, each of which is provided on a connecting member, each of which is arranged at intervals in sequence, each of which is arranged along the length direction of the base 1, and each of the brush rods 21 and the brush head 2101 is arranged in a one-to-one correspondence. When brushing the screw-connected parts, the clamping module 4 can clamp a plurality of screw-connected parts at the same time, and brush each of the screw-connected parts simultaneously through each of the brush rods 21 and the brush head 2101. In the process of brushing, the brushing of a plurality of screw-connected parts can be completed at one time, avoiding the trouble caused by brushing one by one, and improving the brushing efficiency.

[0078] In this embodiment, the brush head 2101 is preferably made of a flexible material, which can ensure the adsorption of the fastener and has high flexibility, so that the fastener can be evenly applied to the threads of the screw-connector without damaging the thread surface. In this embodiment, the brush head 2101 can be made of a sponge material.

[0079] In this embodiment, the base 1 is further provided with a storage module 3 for storing fasteners, and the storage module 3 is connected to the brushing module 2. By providing the storage module 3, the fastener can be continuously and automatically supplied to the brushing module 2. When brushing the screw-connected part, the fastener is loaded into the storage module 3, and the fastener is automatically transported to the position of the brush head 2101 through the storage module 3, so as to ensure the continuous brushing effect of the brush head 2101, and there is no need to manually add the fastener at the brush head 2101, which improves convenience and flexibility, and can also improve work efficiency.

[0080] Specifically, the storage module 3 is a storage box. In order to facilitate the communication between the storage module 3 and the painting module 2, in this embodiment, the storage module 3 is installed on the connecting member, and a channel is formed in the connecting member and the painting rod 21. The storage module 3 is connected to the brush head 2101 through the channel. When the brush head 2101 paints the screw-connected part, the fastener in the storage module 3 flows to the position of the brush head 2101 through the internal channel, so as to achieve the purpose of continuously providing the fastener to the brush head 2101.

[0081] In this embodiment, the channel may be a pipe or a flow channel.

[0082] In this embodiment, in order to facilitate the installation of the storage module 3, a mounting hole 2001 is provided on the connecting member, the mounting hole 2001 is communicated with the internal channel, and the storage module 3 is embedded in the mounting hole 2001. Take the storage box as an example for description:

[0083] In this embodiment, the storage box is made of plastic, and the storage box and the mounting hole 2001 are interference fit, and the opening of the storage box is connected to the internal channel. When brushing the screw-connected part, the brush rod 21 swings up and down, and then the storage box is installed in the mounting hole 2001. Since the storage box and the mounting hole 2001 are interference fit, the storage box is squeezed, and the fastener in the storage box is squeezed into the channel and further enters the brush head 2101 through the channel. Since the brush head 2101 in this embodiment is made of sponge material, the brush head 2101 absorbs the fastener in the channel and further brushes the screw-connected part.

[0084] In this embodiment, the channel includes a first flow channel 2102 located in the connecting member and a second flow channel 2103 located in the brush rod 21. The fastener in the storage module 3 enters the brush head 2101 through the first flow channel 2102 and the second flow channel 2103 in sequence.

[0085] In this embodiment, a second flow channel 2103 is provided in each painting rod 21 . The second flow channel 2103 is arranged along the axial direction of the painting rod 21 . One end of the second flow channel 2103 is connected to the first flow channel 2102 , and the other end is connected to the brush head 2101 .

[0086] In this embodiment, in order to facilitate the first flow channel 2102 to communicate with multiple second flow channels 2103 at the same time, the first flow channel 2102 is divided into two sections. The first section of the first flow channel 2102 is arranged along the axial direction of the brush rod 21, and the second section of the first flow channel 2102 is perpendicular to the first section of the first flow channel 2102, that is, the second section of the first flow channel 2102 is perpendicular to the second flow channel 2103. The specific flow path of the fastener is that the fastener flows out of the storage module 3, enters the first section of the first flow channel 2102, and then enters the second section of the first flow channel 2102, and is distributed to each second flow channel 2103 in turn through the second section of the first flow channel 2102, and finally passes through the second flow channel 2103 to reach the corresponding brush head 2101.

[0087] In this embodiment, in order to facilitate the installation of the clamping module 4, mounting seats are respectively provided at both ends of the base 1, and the mounting seats are integrally formed with the base 1. Of course, the clamping module 4 can also be directly installed on the base 1. In this embodiment, the mounting seats are taken as an example for description.

[0088] In this embodiment, the clamping module 4 includes a clamping member 4202, which is slidably arranged on the base 1. A receiving portion is arranged on the clamping member 4202. The clamping member 4202 reciprocates along the height direction of the storage slot 11 to allow the screw connection member to enter the receiving portion, thereby realizing self-removal of the screw connection member.

[0089] In this embodiment, the clamping member 4202 is a clamping rod, two of which are provided for vertically clamping the screw-connecting member. There is a spacing between the two clamping rods 4202 that is only enough for the threaded section of the screw-connecting member to pass through, so as to form an accommodating portion.

[0090] In this embodiment, the clamping module 4 further includes a sliding member 43 and a sliding shaft 4201, two of which are provided, and the clamping member 4202, the sliding member 43 and the sliding shaft 4201 are provided in one-to-one correspondence. A vibration chute 41 is provided on the mounting seat, and the vibration chute 41 runs through the upper end and the lower end of the mounting seat. The two sliding members 43 are both located in the vibration chute 41 and are provided in parallel. The two sliding members 43 are respectively slidably connected to the side walls of the corresponding mounting seat, that is, the distance between the two sliding members 43 can be adjusted.

[0091] In this embodiment, the sliding shaft 4201 is provided in the sliding member 43 along the axial direction of the sliding member 43 and is slidably connected to the sliding member 43, and the sliding direction of the clamping member 4202 is perpendicular to the sliding direction of the sliding member 43. Both ends of the clamping member 4202 are respectively connected to the corresponding sliding shaft 4201, and the two clamping members 4202 are both arranged horizontally and parallel to each other. By using the sliding shaft 4201 for connection, the sliding shaft 4201 and the clamping member 4202 on one side are U-shaped as a whole.

[0092] In this embodiment, further, the clamping module 4 also includes an adjustable elastic member 4301, and each sliding member 43 is connected to the side wall of the mounting seat through the adjustable elastic member 4301, and each sliding member 43 may be provided with a plurality of adjustable elastic members 4301. In order to further improve the stability of the sliding member 43 when sliding, and at the same time limit the sliding member 43 from sliding out of the vibration chute 41, a limiting hole is also provided in the mounting seat, and a telescopic and slidable support shaft 4302 is provided in the limiting hole, one end of the support shaft 4302 is connected to the bottom wall of the limiting hole, and the other end is connected to the side wall of the sliding member 43, and the axis of the support shaft 4302 is perpendicular to the axis of the sliding member 43. When the sliding member 43 slides, the support shaft 4302 slides together to play a supporting role.

[0093] In this embodiment, in order to facilitate the insertion of the sliding shaft 4201, a support sliding hole 4303 is provided on the sliding member 43, and a sheath is provided in the support sliding hole 4303, and the sheath is interference fit with the sliding shaft 4201. The sheath is made of nylon material, which is wear-resistant, and the sliding shaft 4201 and the sheath are interference fit to prevent the sliding shaft 4201 from sliding at will; at the same time, by pulling the handpiece 42, the sliding shaft 4201 can be pulled to slide synchronously, and after the clamping member is pulled out of the storage slot 11, the screw connection member is in a suspended state.

[0094] In this embodiment, in order to facilitate the sliding of the sliding shaft 4201, a hand piece 42 is connected to the top of the sliding shaft 4201. At the same time, in order to meet the sliding requirements of the sliding member 43, a support slide groove 4203 is provided on the hand piece 42, and the end of each sliding shaft 4201 is clamped in the support slide groove 4203 and the end of the sliding shaft 4201 is slidably connected to the support slide shaft 4302.

[0095] In this embodiment, the specific process of the clamping module 4 clamping the screw connection is as follows:

[0096] The staff member presses the handpiece 42 downward, and the sliding shaft 4201 slides, driving the clamping member 4202 to slide in the storage slot 11. Due to the presence of the adjustable elastic member 4301, the two clamping members 4202 can be elastically extended and retracted, increasing the distance between the two clamping members 4202. During the continuous sliding process, the screw connection can be ensured to fall between the two clamping members 4202. Under the action of the adjustable elastic member 4301, the two clamping members 4202 will move in a direction of approaching each other, so that the screw connection can be clamped, thereby preventing the screw connection from loosening during the painting process, which affects the painting effect.

[0097] After the clamping member has taken the threaded member, the handpiece 42 is pulled upward, so that the clamping member 4202 slides upward along the storage slot 11 until it moves between the two painting modules 2, and then the connecting member is slid to move the brush head 2101 in the direction close to the clamping member 4202 until the brush head 2101 contacts the external thread on the surface of the threaded member, and then the storage module 3 is loaded, and the driving member is started, so that the driving member drives the vibration cam to rotate, thereby realizing the continuous swing of the painting rod 21 and completing the automatic painting of the threaded member. Through the clamping module 4, the purpose of automatically taking the threaded member is achieved, the work efficiency is improved, and the trouble caused by manually taking the threaded member one by one is avoided.

[0098] In this embodiment, in order to make it easier to insert the screw connection between the two clamping members 4202 and avoid the situation where the screw connection cannot be taken out or less screw connection can be taken out at one time, a vibration module 5 is provided on the mounting seat, and the vibration module 5 generates vibration and transmits the vibration to the clamping member 4202. When the clamping member 4202 is clamping the screw connection, the screw connection can become loose through the vibration generated by the vibration module 5, and the clamping member 4202 can be inserted into the screw connection more easily, thereby allowing the screw connection to enter the gap between the two clamping members 4202.

[0099] In this embodiment, the vibration module 5 can also transmit vibration to the clamping member 4202 when the clamping member 4202 clamps the screw-connecting member, so that the screw-connecting member enters the preset position in the accommodating portion. The preset position is that the axis of the screw-connecting member is in a vertical state.

[0100] In this embodiment, the vibration module 5 can be a vibration motor, a mechanical vibrator, a spring-mass system or other structures that can generate vibration. In this embodiment, a vibration motor is taken as an example for specific description.

[0101] Specifically, a groove is provided on one side of the mounting seat away from the storage slot 11, the vibration motor is clamped in the groove, the output shaft of the vibration motor extends into the vibration slide slot 41, and the end of the output shaft of the vibration motor is connected to a pressing vibration head 54. In this embodiment, the pressing vibration head 54 is a cam structure. The vibration motor drives the pressing vibration head to rotate, and can press the sliding members 43 on both sides, so that the clamping member 4202 is in a vibrating state.

[0102] In this embodiment, the vibration motor can be taken out from the groove. When the vibration motor is not placed in the groove, the distance between the two sliding members 43 is smaller than the size of the top-pressing vibration head 54, that is, the distance between the two sliding members 43 is minimum, ensuring that the screw connection can be clamped. When the vibration motor is placed in the groove, the top-pressing vibration head 54 is inserted between the two sliding members 43, so that the distance between the two sliding members 43 becomes larger, which facilitates the insertion of the screw connection. After the extraction of the screw connection is completed, the vibration motor is taken out of the groove, and the distance between the two sliding members 43 is restored to the minimum under the action of the adjustable elastic member 4301.

[0103] In this embodiment, the end of the top-pressing vibration head is a conical structure, which can facilitate insertion between the two sliding members 43.

[0104] In this embodiment, in order to prevent the vibration motor from falling out of the groove during operation, the motor needs to be fixed. Specifically, it includes a limit bracket 51, a second elastic member 52 and a rotating head 53. The limit bracket 51 is L-shaped. One end of the limit bracket 51 is connected to the end of the vibration motor through the second elastic member 52. The rotating head 53 is connected to the other end of the limit bracket 51, and the rotating head 53 is rotatably connected to the mounting seat. The vibration motor is pressed into the groove by the second elastic member 52 to achieve a limit effect and prevent the vibration motor from falling out of the groove; at the same time, the rotation of the rotating head 53 is used to control the swing of the limit bracket 51.

[0105] In this embodiment, the specific working process is: insert the vibration motor into the groove, start the vibration motor, and press down the handpiece 42 at the same time, so that the clamping part 4202 moves vertically in the storage slot 11, and the two clamping parts 4202 cooperate and vibrate the clamping part 4202 to ensure that the clamping part can be smoothly inserted into the screw connection part, and the screw connection part can be self-removed.

[0106] After the extraction of the screw-connector is completed, the vibration motor is taken out from the groove, so that the distance between the two clamping parts 4202 becomes smaller and the screw-connector is clamped. Then the connecting part is pushed so that the brush heads 2101 on both sides are close to each other, and then the storage module 3 is loaded, and the driving part is started so that the driving part drives the cam to rotate, thereby realizing the continuous up and down swing of the painting rod 21, and completing the automatic painting of the screw-connector. Through the clamping module 4 and the vibration module 5, the purpose of automatically taking out the screw-connector is achieved, avoiding the trouble caused by manually taking out the screw-connector one by one. Through the painting module 2, the automatic painting of the screw-connector is achieved, and the work efficiency is improved.

[0107] In this embodiment, in order to further improve the efficiency of automatically taking out the screw-connected component, a limiting module is further provided at the bottom of the storage slot 11 to ensure that the two clamping components 4202 can be smoothly inserted into the screw-connected component.

[0108] Specifically, the limiting module includes a support member 6, a third elastic member 61 and a support frame 63. The support member 6 is arranged at an angle. There are two support members 6. The two support members 6 gradually approach each other from the top of the storage slot 11 to the bottom of the storage slot 11, forming a V-shaped limiting area. The screw connections are placed in the limiting area, and the screw connections are more concentrated for easy extraction.

[0109] In this embodiment, the support frame 63 is arranged at the bottom of the storage tank 11, one end of the support member 6 away from the support frame 63 is hinged to the base 1, and the other end of the support member 6 is slidably arranged on the support frame 63. The third elastic member 61 is arranged at the middle position of the support member 6, and the other end of the third elastic member 61 is connected to the side wall of the base 1.

[0110] In this embodiment, a motor is installed on the base 1, and the output shaft of the motor is connected to a first rotating shaft 6201, which extends into the storage slot 11 and is located below the support member 6. A first cam 62 is installed on the first rotating shaft 6201. The motor drives the first cam 62 to rotate, thereby achieving a swinging effect of the support member 6.

[0111] In this embodiment, the support member 6 may be a vibration plate, which is a device capable of generating vibrations. Specifically, the vibration plate includes various types such as electromagnetic vibration plates, ultrasonic vibration plates, and micro vibration plates. The vibration plate is used to generate vibrations, and at the same time cooperates with the third elastic member 61 to make the vibration plate swing, drive the screw connection in the limiting area to move, and reduce the difficulty of extraction.

[0112] Further, the support frame 63 includes two vertical plates and a horizontal plate, the two vertical plates are connected to the bottom of the storage slot 11, and the horizontal plate is connected to the two vertical plates, forming a "J"-shaped structure. There is a gap between the horizontal plate and the bottom of the storage slot 11. A motor is installed on the base 1, and the output shaft of the motor is connected to the second rotating shaft 6304, the second rotating shaft 6304 extends into the storage slot 11 and is located below the horizontal plate. A second cam 6303 is provided on the second rotating shaft 6304. A toggle member 6301 is slidably installed on the support frame 63, and the toggle member 6301 partially extends into the limiting area. A top pressure head 6302 is provided at one end of the toggle member 6301 near the bottom of the storage slot 11. When the motor drives the second cam 6303 to rotate, the second cam 6303 toggles the top pressure head 6302. The structure of the second cam 6303 is used to realize the up and down sliding of the toggle member 6301, and a stirring effect is generated on the screw-connected member in the limiting area, so that the clamping member can be smoothly inserted into the screw-connected member.

[0113] In this embodiment, a spring may be provided between the top pressure head 6302 and the support frame 63, and under the action of the spring, the toggle member 6301 may be automatically reset, thereby realizing the reciprocating movement of the toggle member 6301 and achieving the effect of continuous operation. Under the synchronous action of the support member 6 and the toggle member 6301, the clamping member can be easily inserted into the screw-connected member in the storage slot 11, reducing the difficulty of extraction.

[0114] In this embodiment, a plurality of toggle members 6301 may be provided, and a plurality of toggle members 6301 may improve the toggle effect. In this embodiment, some motors are not shown in the figure.
