[0039] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[0040] 1. The anti-drop safety valve of the present invention rotates the outer mounting component through the arranged gas core component to connect the outer mounting component with the part to be mounted, so that an air filling and deflation airway is formed between the outer mounting component, the gas core component and the outer sleeve, and then the blocking block is pressed to move the core rod downward as a whole, so that the sealing channel formed between the lower sealing inclined surface and the upper sealing inclined surface is opened, and at this time, the truncated cone section drives the sealing ring to move downward, so that the external inflation can pass through the sealing channel formed by the lower sealing inclined surface and the upper sealing inclined surface in turn, and the external inflation passes through the inside of the inner sleeve ring and the part separated from the truncated cone section and the sealing ring, and then finally fills into the part to be mounted through the outer mounting component. , on the one hand, the arranged wedge ring can not only form a sealing channel when it contacts with the upper sealing inclined surface to prevent the gas of the installed part from surging up to cause the entire gas core component to leak, but on the other hand, the wedge ring can also stop moving when it touches the gasket ring after moving down, so as to prevent the sealing ring from interfering with the gas supply channel formed by the two sets of linked flip components and blocking the external gas from passing through the gas supply channel. After being blocked by the wedge ring, the sealing ring is always located above the gas supply channel, so that the external gas can be quickly supplied. On the other hand, the arranged wedge ring can touch the gasket ring to prevent the compression of the pressure spring from being too large, and the gasket ring can provide annular support for the core rod;

[0041] 2. The anti-drop safety air valve of the present invention can prevent the recoil gas from causing the sealing ring to lose its sealing effect by causing the recoil gas to deform too much when the gas in the installed part recoils. The anti-drop plug ring is positioned laterally with the blocking ring and the bottom surface is positioned by the anti-drop plug ring and the blocking ring. The ball heads of multiple groups of lower ball heads are positioned with the sealing ring and the part of the sealing ring except the upper ball head groove is bonded to the anti-drop plug ring. This can further increase the contact between the sealing ring and the anti-drop plug ring, and when the sealing ring is subjected to gas recoil, the impact force received can be transmitted from bottom to top to the anti-drop plug ring. The insert ring can avoid the independent blocking operation when the sealing ring contacts the blocking ring alone. At the same time, the core rod is provided with an annular support by the arranged gasket ring, which can prevent the core rod from swinging left and right with a large amplitude when falling. When the gas in the to-be-installed part recoils and causes the sealing ring to swing left and right, it can be blocked by the lateral positioning between the arranged anti-drop insert ring and the blocking ring to prevent the sealing ring from having too large a deformation amount in the left and right direction. In addition, pressing multiple sets of ball heads between the upper ball head and the blocking ring can increase the bottom surface positioning area of ​​the upper ball head and the blocking ring, avoiding instability when the surface contacts.

[0042] 3. The anti-drop safety valve of the present invention, through the arranged trigger component, when the gas of the to-be-installed part recoils, the gas will directly surge upward through the gas supply channel formed by the two groups of linked flipping components when the recoil force is small. When the recoil force of the gas of the to-be-installed part increases and can reach the trigger rod to deform, the gas recoil can push the trigger plate upward, and can also drive the trigger rod and the displacement rod to move upward. After the roller moves upward, the two groups of linked flipping components can be pushed upward at the same time and flipped. When the gas recoil force is small, the reset spring will lose its restriction and rebound, so that the limit block returns to the initial position.

[0043] 4. The anti-drop safety air valve of the present invention can push the left flip plate to rotate counterclockwise and push the right flip plate to rotate clockwise after the roller moves up, so that the air supply channel formed between the two sets of flip plates can be expanded, and the lower adjustment rod can be inserted into the upper adjustment rod, and the first hanging spring can be stretched at the same time. Since the air supply channel is expanded, the impact force of gas recoil can be reduced, which is equivalent to reducing the impact force of the recoil gas instantly entering the outer sleeve, which can reduce the impact and extrusion force on the sealing ring, and can It can effectively reduce the deformation of the sealing ring, and after reducing the deformation of the sealing ring, it can promote the lateral and longitudinal blocking effect of the anti-dropping plug ring on the sealing ring, so as to prolong the service life of the anti-dropping plug ring and the sealing ring, and prevent the sealing ring from losing its sealing effect. In addition, when the impact force of the recoil gas increases again, the roller can be squeezed to continue to move upward, which is equivalent to the turning force of the two sets of linked turning components continuing to increase, the lower adjustment rod continues to penetrate into the upper adjustment rod, and the air supply channel formed between the two sets of turning plates will be further expanded to continue to increase and reduce the instantaneous impact force of the recoil gas when it surges from the air supply channel;

[0044] 5. The anti-drop safety valve of the present invention can reduce the pulling force of the inner ring on the first hanging spring after the inner ring contacts the airbag through the inner ring, so as to prevent the inner ring from over-stretching the first hanging spring and exceeding the deformation range of the first hanging spring. On the other hand, it can reduce the instantaneous impact force when the inner ring slides in the upper adjustment rod, which may cause the inner ring to stop.

[0045] 6. The anti-slip safety air valve of the present invention has a follow-up limiting component, which can push the follow-up rod into the follow-up blocking seat after the flip plate is reversed and touches the external pressing plate, and can make the internal pressing plate retreat to pull the second hanging spring for stretching, which can prevent the linkage flip component as a whole from losing the ability to form an air supply channel due to a large gas recoil force. After the external pressing plate moves to the second position, which is equivalent to the external pressing plate retreating to the rear of the permanent magnet, the permanent magnet can contact the flip plate, and the permanent magnet can adsorb the permanent magnet plate, so that the flip plate is finally positioned on the permanent magnet to form a limit. At this time, the air supply channel formed between the two groups of flip plates reaches the maximum value, which can further enhance the stability of the linkage flip component as a whole during use and prevent the linkage flip component from losing the ability to form an air supply channel.

Arranged in the inner sleeve ring 21 and in conflict with the inner sleeve ring 21, it is located above the lower hook section 22, and a gasket ring 24 is detachably arranged on it; a blocking ring 25, which is detachably arranged on the locking ring 23, has a raised groove on its side surface, and has a lower ball head groove on its bottom surface; an anti-falling plug ring 26, which has a protrusion 261 that can be inserted into the protrusion groove, and when the protrusion 261 is inserted into the protrusion groove, it can form a side limit with the blocking ring 25, and it also has an upper ball head 262 that can be inserted into the lower ball head groove, and when the upper ball head 262 is inserted into the lower ball head groove, it can form a bottom limit with the blocking ring 25, and it also has a There is a lower ball head 263; a sealing ring 27, the top surface of which has an upper ball head groove, when the upper ball head groove and the lower ball head 263 are in contact with each other, it can be positioned on the anti-falling plug ring 26, and the part without the upper ball head groove is bonded to the anti-falling plug ring 26; a core rod 28, which is slidably arranged in the inner ring 21, and has a truncated cone section 281 on it, and a sealing ring 282 is detachably arranged on the truncated cone section 281, and the sealing ring 282 and the sealing ring 27 are in contact with each other, and a blocking block 283 is detachably arranged on the top, and a wedge ring 284 is detachably arranged on it, and a lower sealing inclined surface 285 is provided on the wedge ring 284, and the lower sealing inclined surface 285 and the upper When the sealing bevels 211 are in conflict with each other, a sealing channel can be formed between the inner ring 21 and the sealing ring 282, on which a compression spring 29 is slidably arranged; an outer mounting component 3 is detachably installed at the bottom of the chassis 12, and two groups of trigger components 4 are detachably arranged in the outer mounting component 3, and two groups of linkage flipping components 5 are detachably arranged in the outer mounting component 3, and the two groups of linkage flipping components 5 are respectively in conflict with the two groups of trigger components 4, and the two groups of linkage flipping components 5 form an air supply channel in the initial state, and a follow-up limiting component 6 is detachably arranged in the outer mounting component 3, and the follow-up limiting component 6 is located above the linkage flipping component 5.

[0060] The overall idea on which the present invention is based is that, through the arranged air core component 2, the outer mounting component 3 is rotated so that the outer mounting component 3 is connected to the part to be mounted, so that an air filling and deflation airway is formed between the outer mounting component 3, the air core component 2 and the outer sleeve 1, and then the blocking block 283 is pressed to make the core rod 28 move downward as a whole, so that the sealing channel formed between the lower sealing slope 285 and the upper sealing slope 211 is opened, and at this time, the frustum section 281 drives the sealing ring 282 to move downward, so that the external inflation can pass through the sealing channel formed by the lower sealing slope 285 and the upper sealing slope 211 in turn, and the external inflation passes through the inside of the inner sleeve ring 21 and the part where the frustum section 281 and the sealing ring 282 are separated, and then finally fills into the part to be mounted through the outer mounting component 3. In the mounting part, the arranged wedge ring 284 can not only form a sealing channel when it contacts with the upper sealing inclined surface 211 to prevent the gas of the mounting part from surging up to cause the gas core component 2 to leak as a whole, but also can be used in conjunction with the sealing ring 27. Even when the performance of the sealing ring 27 is reduced, it can still assist the sealing ring 27 to seal the gas surging up. On the other hand, the wedge ring 284 can stop moving when it touches the gasket 24 after moving down, so as to prevent the sealing ring 282 from interfering with the air supply channel formed by the two sets of linked flip components 5 and blocking the outside gas from passing through the air supply channel. After being blocked by the wedge ring 284, the sealing ring 282 is always located above the air supply channel, so that the outside gas can be quickly supplied. On the other hand, the arranged wedge The shaped ring 284 touches the gasket 24 and can prevent the compression of the compression spring 29 from being too large, and the gasket 24 can provide annular support for the core rod 28. When the gas in the to-be-installed part recoils, in order to prevent the recoil gas from causing the sealing ring 27 to deform too much and causing the sealing ring 27 to lose its sealing effect, the anti-falling plug ring 26 is positioned laterally with the blocking ring 25 and the bottom surface of the anti-falling plug ring 26 and the blocking ring 25 are positioned, and multiple groups of lower ball heads 263 are positioned with the sealing ring 27 for ball head positioning and the part of the sealing ring 27 without the upper ball head groove is bonded to the anti-falling plug ring 26, so that the contact between the sealing ring 27 and the anti-falling plug ring 26 can be further increased, and when the sealing ring 27 is subjected to gas recoil, the impact force can be automatically dissipated. The sealing ring 27 is then transferred from bottom to top to the anti-dropping plug ring 26, thereby avoiding the independent blocking operation when the sealing ring 27 contacts the blocking ring 25 alone. At the same time, the core rod 28 is provided with an annular support by the arranged gasket ring 24, which can also prevent the core rod 28 from swinging left and right with a large amplitude when falling. When the gas in the part to be installed recoils and causes the sealing ring 27 to swing left and right, it can be blocked by the lateral positioning between the arranged anti-dropping plug ring 26 and the blocking ring 25, so as to prevent the sealing ring 27 from having too large a deformation amount in the left and right direction. In addition, by pressing multiple sets of ball heads between the upper ball head 262 and the blocking ring 25, the bottom surface positioning area of ​​the upper ball head 262 and the blocking ring 25 can be increased, thereby avoiding instability when the surface contacts. By arranging the trigger component 4,When the gas of the installation part recoils, if the recoil force is small, it will directly surge upward through the gas supply channel formed by the two groups of linked flipping components 5. When the recoil force of the gas of the installation part increases and can reach the trigger rod 43 to deform, the gas recoil can push the trigger plate 45 to move upward, and can also drive the trigger rod 43 and the displacement rod 46 to move upward. After the roller 47 moves upward, the two groups of linked flipping components 5 can be pushed upward at the same time and the two groups of linked flipping components 5 can be flipped. When the gas recoil force is small, the reset spring 49 will lose its restriction and rebound, so that the limit block 44 returns to the initial position. Through the arranged linked flipping component 5, after the roller 47 moves upward, it can push the flip plate 52 on the left side to reverse the clockwise direction. The needle rotates, and at the same time, the flip plate 52 on the right is pushed to rotate clockwise, which can expand the air supply channel formed between the two sets of flip plates 52, and at the same time make the lower adjusting rod 55 penetrate into the upper adjusting rod 57, and at the same time stretch the first hanging spring 59. Since the air supply channel is expanded, the impact force of the gas recoil can be reduced, which is equivalent to reducing the impact force of the recoil gas that instantly enters the outer sleeve 1, which can reduce the impact and extrusion force on the sealing ring 27, and can effectively slow down the deformation of the sealing ring 27. After slowing down the deformation of the sealing ring 27, it can promote the lateral and longitudinal blocking effect of the anti-dropping plug ring 26 on the sealing ring 27, so as to delay the service life of the anti-dropping plug ring 26 and the sealing ring 27, which can To prevent the sealing ring 27 from losing its sealing effect, in addition, when the impact force of the recoil gas increases again, the roller 47 can be squeezed to continue to move upward, which is equivalent to the flipping force of the two sets of linked flipping components 5 continuing to increase, and the lower adjusting rod 55 continues to penetrate into the upper adjusting rod 57, and the air supply channel formed between the two sets of flip plates 52 will be further expanded to continue to increase and reduce the instantaneous impact force of the recoil gas when it surges from the air supply channel. Through the arrangement of the inner ring 58, on the one hand, when the inner ring 58 contacts the airbag 591, the pulling force of the inner ring 58 on the first hanging spring 59 can be reduced to prevent the inner ring 58 from over-stretching the first hanging spring 59 and exceeding the deformation range of the first hanging spring 59, and on the other hand, it can reduce the inner ring 58 on the upper adjusting rod In the case where the inner ring 58 is forced to stop due to the instantaneous impact force when sliding inside 57, the follower limiting component 6 is arranged, and when the flip plate 52 is reversed and touches the external pressing plate 63, the external pressing plate 63 pushes the follower rod 62 into the follower blocking seat 61, and the internal pressing plate 64 can retreat to pull the second hanging spring 65 for stretching, which can prevent the linkage flip component 5 from losing the ability to form an air supply channel when it is subjected to a large gas recoil force as a whole. When the external pressing plate 63 moves to the second position, that is, when the external pressing plate 63 retreats to the rear of the permanent magnet 66, the permanent magnet 66 can contact the flip plate 52, and the permanent magnet 66 can adsorb the permanent magnet plate.So that the flip plate 52 is finally positioned on the permanent magnet 66 to form a limit, at this time, the air supply channel formed between the two groups of flip plates 52 reaches the maximum value, which can further enhance the overall stability of the linkage flip member 5 when in use and prevent the linkage flip member 5 from losing the ability to form the air supply channel;

[0061] It should also be noted that, in the present case, the anti-dropping plug ring 26 is detachably provided with a built-in rubber ring on the outer circumference, and the built-in rubber ring and the anti-dropping plug ring 26 are integrally formed, which is equivalent to being able to transfer to the built-in rubber ring after the anti-dropping plug ring 26 is impacted, so as to synchronously block the sealing ring 27, and the shape of the ferrule 15 is O-shaped, and the ferrule 15 is tied to the periphery of the built-in rubber ring, the ferrule 15 can lock the built-in rubber ring to prevent the built-in rubber ring from lateral displacement, so as to further strengthen the blocking effect of the built-in rubber ring and the anti-dropping plug ring 26 on the sealing ring 27, so as to prevent the sealing by the sealing ring 27 alone. Similarly, the built-in rubber ring can also be further locked by the arranged hexagonal nut 13, so as to enhance the stability of the built-in rubber ring and the anti-dropping plug ring 26 when in use.

[0062] In some embodiments, more specifically, in order to improve the contact stability between the compression spring 29, the blocking block 283 and the inner ring 21, the compression spring 29 is located at the bottom of the blocking block 283 and the top of the inner ring 21, and the compression spring 29 is respectively in conflict with the blocking block 283 and the inner ring 21, and the size of the compression spring 29 is matched with the size of the core rod 28.

[0063] In some embodiments, more specifically, in order to enable the wedge ring 284 to touch the gasket 24, the gasket 24 is located below the wedge ring 284, which can prevent the wedge ring 284 from continuing to move downward along the length direction of the inner ring 21 when the wedge ring 284 conflicts with the gasket 24.

[0064] In some embodiments, in order to enable the conical segment 281 to move downward along the inner ring 21, the conical segment 281 can pass through the sealing ring 27, the size of the sealing ring 282 is adapted to the size of the sealing ring 27, and the sealing ring 282 can be detached from the sealing ring 27.

[0065] Next, a more specific structure and construction is given to the external mounting member 3 as a whole for further explanation. The external mounting member 3 includes an external mounting tube 31, on which there is a sealing rubber ring, and the sealing rubber ring and the chassis 12 are mutually in conflict, and the external mounting member 3 is connected to the chassis 12. On the inner wall thereof, there is an internal thread section 36, on which a second ear plate 32 is detachably arranged, and the second ear plate 32 and the first ear plate 16 are mutually in conflict, and a limiting screw 33 is removably penetrated on the second ear plate 32, and the limiting screw 33 can pass through the second ear plate 32 and the first ear plate 16 in sequence; a lower nut 34, which is rotatably arranged on the limiting screw 33, and the second ear plate 32 is mutually in conflict; and an upper nut 35, which is rotatably installed on the limiting screw 33, and the first ear plate 16 is mutually in conflict;

[0066] Next, the use principle of the outer mounting member 3 as a whole is further explained. The outer mounting tube 31 can be quickly installed on the part to be installed through the internal thread section 36. The limiting screw 33 is sequentially inserted into the second ear plate 32 and the first ear plate 16, so that the connection between the outer mounting tube 31 as a whole and the chassis 12 can be further strengthened.

[0067] It should also be noted that the part to be installed can be a bicycle or electric vehicle tire, etc., or it can be other chemical inflatable kettles such as reactors. Of course, there are no excessive restrictions in the present invention.

[0068] Next, the trigger member 4 is given a more specific structure and construction as a whole for further explanation. The trigger member 4 includes a trigger base 41, which is detachably arranged in the outer mounting tube 31, and a mounting seat 42 is detachably arranged on it; a trigger rod 43, which is slidably arranged in the trigger base 41, and a limit block 44 is detachably arranged on the top of the trigger base 41, and the limit block 44 is in conflict with the trigger base 41; a trigger plate 45, which is detachably arranged on the trigger rod 43 and is located at the bottom of the trigger base 41; a displacement rod 46, which is detachably mounted on the trigger plate 45, which can pass through the trigger base 41, and a roller 47 is rotatably arranged on one end of the displacement rod 46 passing through the trigger base 41, and a roller pad 48 is detachably sleeved on the roller 47; and a reset spring 49, which is removably sleeved on the trigger rod 43 and respectively conflicts with the trigger base 41 and the trigger plate 45;

[0069] Next, the overall working principle of the trigger component 4 is further explained. When the gas of the to-be-installed part recoils, the gas will directly surge upward through the gas supply channel formed by the two groups of linked flipping components 5 if the recoil force is small. When the recoil force of the gas of the to-be-installed part increases and can reach the trigger rod 43 to deform, the gas recoil can push the trigger plate 45 upward, and can also drive the trigger rod 43 and the displacement rod 46 to move upward. After the roller 47 moves upward, the two groups of linked flipping components 5 can be pushed upward at the same time and flipped. When the gas recoil force is small, the reset spring 49 will lose its restriction and rebound, so that the limit block 44 returns to its initial position.

[0070] Next, the linkage flip member 5 is given a more specific structure and construction as a whole for further explanation. The linkage flip member 5 includes a first connecting seat 51, which is detachably mounted on the outer mounting tube 31, in which a flip plate 52 is slidably arranged, a blocking plate 53 is detachably arranged on the flip plate 52, and the blocking plate 53 is in conflict with the roller 47, a permanent magnet plate is also detachably arranged on the flip plate 52, and a second connecting seat 54 is also detachably arranged on the flip plate 52; a lower adjusting rod 55 is rotatably arranged on the second connecting seat 5 4, on which an inner ring 58 is detachably arranged; a third connecting seat 56, which is detachably arranged on the outer mounting tube 31, in which an upper adjusting rod 57 is rotatably arranged, a plug cavity is provided in the upper adjusting rod 57, and the plug cavity can be penetrated by the inner ring 58 and the lower adjusting rod 55, a first hanging spring 59 is provided in the plug cavity, and one end of the first hanging spring 59 is connected to the inner top wall of the upper adjusting rod 57, and the other end of the first hanging spring 59 is connected to one side of the inner ring 58; and an air bag 591, which is detachably installed in the plug cavity and is located above the inner ring 58;

[0071] Next, the overall working principle of the linkage flip member 5 is further explained. When the roller 47 moves upward, it can push the flip plate 52 on the left to rotate counterclockwise, and at the same time push the flip plate 52 on the right to rotate clockwise, so that the air supply channel formed between the two sets of flip plates 52 can be expanded, and at the same time the lower adjustment rod 55 can be inserted into the upper adjustment rod 57, and the first hanging spring 59 can be stretched at the same time. Since the air supply channel is expanded, the impact force of the gas recoil can be reduced, which is equivalent to reducing the impact force of the recoil gas that instantly enters the outer sleeve 1, which can reduce the impact and extrusion force on the sealing ring 27, and can effectively reduce the deformation of the sealing ring 27. After reducing the deformation of the sealing ring 27, it can promote the lateral and longitudinal blocking effect of the anti-falling plug ring 26 on the sealing ring 27, so as to delay the anti-falling plug ring 26 and the service life of the sealing ring 27 can prevent the sealing ring 27 from losing its sealing effect. In addition, when the impact force of the recoil gas increases again, the roller 47 can be squeezed to continue to move upward, which is equivalent to the flipping force of the two sets of linked flipping components 5 continuing to increase. The lower adjusting rod 55 continues to penetrate into the upper adjusting rod 57, and the air supply channel formed between the two sets of flip plates 52 will be further expanded to continue to increase and reduce the instantaneous impact force of the recoil gas when it surges from the air supply channel. Through the inner ring 58, on the one hand, when the inner ring 58 contacts the airbag 591, the pulling force of the inner ring 58 on the first hanging spring 59 can be reduced to prevent the inner ring 58 from over-stretching the first hanging spring 59 and exceeding the deformation range of the first hanging spring 59. On the other hand, it can reduce the instantaneous impact force of the inner ring 58 when it slides in the upper adjusting rod 57, causing the inner ring 58 to be forced to stop.

[0072] In some embodiments, more specifically, the inner ring 58 is in contact with the inner wall of the upper adjusting rod 57 , the airbag 591 is in contact with the inner wall of the upper adjusting rod 57 , and the length dimension of the lower adjusting rod 55 is greater than the length dimension of the upper adjusting rod 57 .

[0073] Next, a more specific structure and construction is given to the whole follow-up limiting member 6 for further explanation. The follow-up limiting member 6 includes a follow-up blocking seat 61, which is detachably mounted on the outer mounting tube 31 and has a displacement cavity therein; a follow-up rod 62, which is slidably arranged in the displacement cavity, and a built-in pressing plate 64 is detachably arranged on it, and the built-in pressing plate 64 is located in the displacement cavity; a second hanging spring 65, one end of which is removably hung on the inner wall of the follow-up blocking seat 61, and the other end of which is removably hung on the built-in pressing plate 64; an external pressing plate 63, which is detachably arranged on the end of the follow-up rod 62 away from the built-in pressing plate 64; and a permanent magnet 66, which is detachably mounted on the follow-up blocking seat 61, which is located on one side of the external pressing plate 63, and its magnetism is opposite to that of the permanent magnetic plate. When it contacts the permanent magnetic plate, it can adsorb the permanent magnetic plate;

[0074] Next, the overall use principle of the follower limiting component 6 is further explained. After the flip plate 52 is reversed and touches the external pressing plate 63, the external pressing plate 63 pushes the follower rod 62 into the follower blocking seat 61, and the internal pressing plate 64 can retreat to pull the second hanging spring 65 for stretching, which can prevent the linkage flip component 5 from losing the ability to form an air supply channel when it is subjected to a large gas recoil force. After the external pressing plate 63 moves to the second position, which is equivalent to the external pressing plate 63 retreating to the rear of the permanent magnet 66, the permanent magnet 66 can contact the flip plate 52, and the permanent magnet 66 can adsorb the permanent magnet plate, so that the flip plate 52 is finally positioned on the permanent magnet 66 to form a limit. At this time, the air supply channel formed between the two groups of flip plates 52 reaches the maximum value, which can further enhance the overall stability of the linkage flip component 5 during use and prevent the linkage flip component 5 from losing the ability to form an air supply channel.

[0075] In some embodiments, more specifically, in order to enhance the stability of the built-in pressing plate 64 sliding on the inner wall of the follow-up blocking seat 61, the built-in pressing plate 64 contacts the inner wall of the follow-up blocking seat 61, the built-in pressing plate 64 can slide along the inner wall of the follow-up blocking seat 61 and the built-in pressing plate 64 cannot touch the inner bottom wall of the follow-up blocking seat 61, and the size of the built-in pressing plate 64 is smaller than the size of the external pressing plate 63.

[0076] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
