Description

Technical Field

[0001] This invention relates to the field of hollow sunshade window technology, and in particular to a slanted guide self-locking and unlocking mechanism for hollow sunshade controllers. Background Technology

[0002] Insulating glass is a type of sunshade product that integrates sunshade functionality into the glass panes. It uses an external actuator to magnetically control the movement of a follower, which in turn drives a pull cord to control the raising and lowering of the sunshade components. The sunshade components typically use blinds or honeycomb blinds. Taking insulating glass with blinds as an example, when the blinds are fully lowered, their weight is supported by a ladder cord. As the cord is raised or lowered, the load on the cord increases or decreases with each blind raised or lowered, resulting in a stepped increase or decrease in the cord's load.

[0003] To balance the operating force of the controller, a counterweight is usually placed on one side of the pull cord. However, the weight of the counterweight is constant. When the weight of the lifted louver is greater than the counterweight, the louver will move downwards a certain distance when the controller is released. Conversely, when the weight of the louver is less than the counterweight, the louver will move upwards a certain distance when the controller is released, making it impossible to maintain the louver in the desired position. Existing solutions typically increase the frictional resistance at the controller end to accommodate changes in the weight of the louver under different pulling forces. However, this method is problematic for large-area insulated louvered windows. Due to the large load on the louvers, the frictional resistance significantly increases the operating force of the controller, causing difficulties in using the louvers. Furthermore, for louvers with very light weight or very short travel, counterweights are often not used, further complicating the operation of keeping the louvers hovering at the desired position. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a slanted guide type hovering unlocking mechanism for a hollow sunshade operator. Through the cooperation of the self-locking trigger block, the unlocking trigger block and the slanted guide type lock assembly, the slanted guide type lock can be quickly unlocked when the operator is lifted or pulled down, and the slanted guide type lock can be quickly self-locked when the operator stops moving; thus realizing the hovering of the sunshade component at the required position.

[0005] The technical solution adopted by this invention to solve its technical problem is: a slanted guide self-locking unlocking mechanism for a hollow sunshade operator, comprising a spacer bar, a follower for responding to the operator's pull-down or pull-up action, and a pull rope connecting block for connecting to a pull rope; a vertical sliding groove with a left opening is provided on the left side of the spacer bar; a slanted guide self-locking unlocking component is installed in the sliding groove; the slanted guide self-locking unlocking component includes a self-locking trigger block, an unlocking trigger block located below the self-locking trigger block, and a [missing information - likely a component name] located below the self-locking trigger block. A slanted guide lock assembly between the unlocking trigger block and the slanted guide lock assembly; the slanted guide lock assembly includes a first slanted guide lock member and a second slanted guide lock member; the first slanted guide lock member includes a first slanted guide lock block, a bearing is rotatably mounted on the right side of the first slanted guide lock block, and the left end face of the first slanted guide lock block is a first track mating surface for engaging with the left end face of the inner side of the slide groove; the second slanted guide lock member includes a second slanted guide lock block, and a slanted guide groove is formed on the left end face of the second slanted guide lock block, the slanted guide groove being inclined from left to right from top to bottom; the right side of the second slanted guide lock block... The end face is a second track mating surface for engaging with the right end face inside the slide groove; the self-locking trigger block includes a first mounting part fixedly installed with the pull rope connecting block, a first actuating part corresponding to the bottom end of the first inclined guide lock, and a second actuating part corresponding to the top end of the second inclined guide lock; the unlocking trigger block includes a second mounting part installed with the follower, a third actuating part corresponding to the top end of the first inclined guide lock, and a fourth actuating part corresponding to the bottom end of the second inclined guide lock; the bearing engages with the inclined guide groove, for... When the bearing moves upward relative to the inclined guide groove, the bearing presses against the inclined guide groove, causing the right end face of the second inclined guide locking block to press against the right end face of the inner side of the slide groove, and the left end face of the first inclined guide locking block to press against the left end face of the inner side of the slide groove, thus achieving self-locking; it is also used when the bearing moves downward relative to the inclined guide groove, the bearing no longer presses against the inclined guide groove, so that the right end face of the second inclined guide locking block no longer presses against the right end face of the inner side of the slide groove, and the left end face of the first inclined guide locking block no longer presses against the left end face of the inner side of the slide groove, thus achieving unlocking.

[0006] Furthermore, when the follower is suspended without being lifted or pulled down by the manipulator, and the upward tension at the load end of the pull rope is greater than the downward tension at the operating end of the pull rope, the self-locking trigger block is used to follow the pull rope connecting block to move upward, thereby causing the first actuating part to move the oblique guide first locking member upward, causing the bearing to move upward relative to the oblique guide groove, thus achieving self-locking.

[0007] Furthermore, the first locking member of the inclined guide is fixedly connected to the self-locking trigger block.

[0008] Furthermore, when the follower is suspended without being lifted or pulled down by the manipulator, and the upward tension at the load end of the pull rope is less than the downward tension at the operating end of the pull rope, the self-locking trigger block is used to follow the pull rope connecting block downward, thereby causing the second actuating part to move the oblique guide second locking member downward, causing the oblique guide groove to move downward relative to the bearing, thus achieving self-locking.

[0009] Furthermore, a counterweight is also fixedly connected between the first mounting part and the rope connecting block.

[0010] Furthermore, a spring is installed on the top side of the first actuating part of the self-locking trigger block, and the top side of the spring cooperates with the bottom end of the first inclined guide locking member; the spring is used to provide an upward elastic force for the first inclined guide locking member, so that when the second inclined guide locking member moves downward relative to the first inclined guide locking member, the first inclined guide locking member does not follow the second inclined guide locking member downward; a spring mounting groove is provided on the top side of the first actuating part, and the bottom end of the spring is placed in the spring mounting groove.

[0011] Furthermore, when the follower moves upward in response to the lifting action of the manipulator, the unlocking trigger block is used to follow the follower to move upward, and the fourth actuating part pushes the oblique guide second locking member upward, so that the oblique guide groove moves upward relative to the bearing to achieve unlocking.

[0012] Furthermore, when the follower moves downward in response to the pull-down action of the manipulator, the unlocking trigger block is used to follow the follower's downward movement, and the third toggle part moves the first locking member of the inclined guide downward, causing the bearing to move downward relative to the inclined guide groove, thereby unlocking.

[0013] Furthermore, the self-locking trigger block also includes a guide portion, with rollers respectively provided on the front and rear sides of the guide portion, and the rollers rollingly engaging with the left and right end faces of the inner side of the groove of the spacer strip.

[0014] Furthermore, the right end face of the first inclined guide locking block is configured as a first inclined surface that slopes from top to bottom and from left to right; the left end face of the second inclined guide locking block is configured as a second inclined surface that slopes from top to bottom and from left to right; the first inclined surface of the first inclined guide locking block and the second inclined surface of the second inclined guide locking block are clearance-fitted; a mounting groove is provided in the middle area of ​​the first inclined surface, and a mounting shaft in the front-to-back direction is installed in the mounting groove; the bearing is fitted onto the mounting shaft; the inclined guide groove is opened on the second inclined surface; the inclination angles of the right end faces of the first inclined surface, the second inclined surface, and the inclined guide groove are consistent.

Detailed Implementation

[0040] To enhance understanding of the present invention, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain the invention and do not limit the scope of protection of the invention.

[0041] Example 1

[0042] Please refer to Figures 1 to 16 As shown, this embodiment provides a slanted self-locking unlocking mechanism for a hollow sunshade operator, including a spacer 1, a follower 2 that moves in response to the operator's pull-down or pull-up action, and a pull rope connecting block 3 for connection with a pull rope; the spacer 1 has a vertical slide groove 11 with a left opening on its left side; the slide groove 11 is equipped with a slanted self-locking unlocking assembly 5; the slanted self-locking unlocking assembly 5 includes a self-locking trigger block 51, an unlocking trigger block 52 located below the self-locking trigger block 51, and a slanted lock assembly 53 located between the self-locking trigger block 51 and the unlocking trigger block 52; the slanted lock assembly 53 includes a slanted first... The system comprises a locking element 531 and a second inclined guide locking element 532. The first inclined guide locking element 531 includes a first inclined guide locking block 5311, a bearing 5313 rotatably mounted on the right side of the first inclined guide locking block 5311, and a first track mating surface 5315 for engaging with the left end face of the inner side of the slide groove 11. The second inclined guide locking element 532 includes a second inclined guide locking block 5321, a guide groove 5324 formed on the left end face of the second inclined guide locking block 5321, the guide groove 5324 being inclined from top to bottom and from left to right. The right end face of the second inclined guide locking block 5321 is for engaging with the right end face of the inner side of the slide groove 11. The second track mating surface 5322; the self-locking trigger block 51 includes a first mounting part 511 fixedly installed with the pull rope connecting block 3, a first actuating part 513 corresponding to the bottom end of the inclined guide first locking member 531, and a second actuating part 514 corresponding to the top end of the inclined guide second locking member 532; the unlocking trigger block 52 includes a second mounting part 521 installed with the follower 2, a third actuating part 522 corresponding to the top end of the inclined guide first locking member 531, and a fourth actuating part 523 corresponding to the bottom end of the inclined guide second locking member 532; the bearing 5313 mates with the inclined guide groove 5324, for use when the bearing 5313 is relative to the inclined guide groove 5324. When the guide groove 5324 moves upward, under the action of the bearing 5313 pressing the oblique guide groove 5324, the right end face of the second oblique guide locking block 5321 is pressed and engaged with the inner right end face of the slide groove 11, and the left end face of the first oblique guide locking block 5311 is pressed and engaged with the inner left end face of the slide groove 11, thus achieving self-locking; it is also used to prevent the bearing 5313 from pressing the oblique guide groove 5324 when the bearing 5313 moves downward relative to the oblique guide groove 5324, so that the right end face of the second oblique guide locking block 5321 is no longer pressed and engaged with the inner right end face of the slide groove 11, and the left end face of the first oblique guide locking block 5311 is no longer pressed and engaged with the inner left end face of the slide groove 11, thus achieving unlocking.

[0043] Please refer to the following: Figure 11 As shown, when the follower 2 is suspended without being lifted or pulled down by the operator, and the upward tension of the pull rope at the load end is greater than the downward tension of the pull rope at the operating end, the self-locking trigger block 51 is used to follow the pull rope connecting block 3 to move upward, thereby causing the first actuating part 513 to move the oblique guide first locking member 531 upward, causing the bearing 5313 to move upward relative to the oblique guide groove 5324, thus achieving self-locking.

[0044] Please refer to the following: Figure 14 As shown, when the follower 2 is suspended without being lifted or pulled down by the operator, when the upward tension of the pull rope at the load end is less than the downward tension of the pull rope at the operating end, the self-locking trigger block 51 is used to follow the pull rope connecting block 3 to move downward, thereby causing the second actuating part 514 to move the inclined guide second locking member 532 downward, causing the inclined guide groove 5324 to move downward relative to the bearing 5313, thus achieving self-locking.

[0045] Please refer to the following: Figure 3 and Figure 14 As shown, a spring 518 is installed on the top side of the first actuating part 513 of the self-locking trigger block 51, and the top side of the spring 518 cooperates with the bottom end of the inclined guide first locking member 531; the spring 518 is used to provide an upward elastic force for the inclined guide first locking member 531, so that when the inclined guide second locking member 532 moves downward relative to the inclined guide first locking member 531, the inclined guide first locking member 531 does not follow the inclined guide second locking member 532 downward; a spring mounting groove 515 is provided on the top side of the first actuating part 513, and the bottom end of the spring 518 is placed in the spring mounting groove 515.

[0046] Please refer to the following: Figure 12 and Figure 15 As shown, when the follower 2 moves upward in response to the lifting action of the manipulator, the unlocking trigger block 52 is used to follow the follower 2 to move upward, and the fourth toggle part 523 toggle the oblique guide second locking member 532 upward, so that the oblique guide groove 5324 moves upward relative to the bearing 5313 to achieve unlocking.

[0047] Please refer to the following: Figure 13 and Figure 16 As shown, when the follower 2 moves downward in response to the pull-down action of the manipulator, the unlocking trigger block 52 is used to follow the follower 2 to move downward, and the third toggle part 522 toggle the first locking member 531 downward, so that the bearing 5313 moves downward relative to the inclined guide groove 5324 to achieve unlocking.

[0048] Refer to Figure 3 and Figure 4 As shown, the self-locking trigger block 51 also includes a guide portion 516, and rollers 517 are respectively provided on the front and rear sides of the guide portion 516. The rollers 517 are in rolling cooperation with the left and right end faces of the inner side of the groove 11 of the spacer 1.

[0049] Refer to Figure 7 and Figure 8 As shown, the right end face of the first inclined guide locking block 5311 is configured as a first inclined surface 5312 that slopes from top to bottom and from left to right; the left end face of the second inclined guide locking block 5321 is configured as a second inclined surface 5323 that slopes from top to bottom and from left to right; the first inclined surface 5312 of the first inclined guide locking block 531 and the second inclined surface 5323 of the second inclined guide locking block 532 are clearance-fitted; a mounting groove is provided in the middle area of ​​the first inclined surface 5312, and a mounting shaft in the front-to-back direction is installed in the mounting groove; the bearing 5313 is fitted onto the mounting shaft; the inclined guide groove 5324 is opened on the second inclined surface 5323; the inclination angles of the right end faces of the first inclined surface 5312, the second inclined surface 5323, and the inclined guide groove 5324 are consistent. By utilizing the contact between the bearing and the inclined guide groove, while the first inclined surface and the second inclined surface do not contact each other, the friction between the first inclined guide locking member 531 and the second inclined guide locking member 532 can be effectively reduced, thus preventing the friction from affecting the relative movement of the first inclined guide locking member 531 and the second inclined guide locking member 532 and thus losing the self-locking and unlocking functions.

[0050] To address the situation where the weight of the sunshade component increases or decreases in a stepped manner when lifted or pulled down, a counterweight 4 can be installed between the first mounting part 511 and the pull rope connecting block 3; alternatively, no counterweight may be installed. Under normal circumstances, the downward pull force on the operating end of the pull rope is greater than the upward pull force under the load of one blade but less than the upward pull force under the load of all blades. In this case, when the operator performs an upward or downward movement, taking the installation of counterweight 4 as an example, the following two situations will occur:

[0051] In the first scenario, the upward tension on the pull rope from the load end is greater than the downward tension on the pull rope from the operating end. In this case, the corresponding hovering self-locking, lift-to-unlock, and pull-down-to-unlock mechanisms are as follows:

[0052] Hover self-locking: Please refer to Figure 11 As shown, after being lifted or pulled down to a certain position by the operator and then released, the pull rope connects to the pull rope connecting block, counterweight, and self-locking trigger block. At the same time, the spring also releases its elastic force. Under the combined action, the first inclined guide lock and the unlocking trigger block will move upward. The first inclined guide lock moves upward relative to the second inclined guide lock, causing the bearing to move upward as well. During the upward movement of the bearing, under the oblique action of the inclined guide groove, the bearing will squeeze the inclined guide groove, causing the first inclined guide lock to move to the left and the second inclined guide lock to move to the right. This causes the first track mating surface of the first inclined guide lock block to press against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide lock block to press against the right end face of the inner side of the slide groove. As a result, the inclined guide lock assembly is locked in the slide groove, forming a self-lock. The corresponding pull rope connecting block, counterweight, self-locking trigger block, unlocking trigger block, and follower also enter a suspended state.

[0053] Pull up to unlock: Please refer to Figure 12 As shown, when the lever is lifted, the unlocking trigger block is also lifted synchronously under the action of the follower. During the upward movement of the unlocking trigger block, the fourth actuating part will first contact the second inclined guide lock and drive the second inclined guide lock to move upward, causing the inclined guide groove and the bearing to loosen slightly. This will prevent the first track mating surface of the first inclined guide lock block from pressing against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide lock block from pressing against the right end face of the inner side of the slide groove. Consequently, the inclined guide lock assembly will no longer be stuck in the slide groove, completing the unlocking. Then, the self-locking trigger block, counterweight, pull rope connecting block, first inclined guide lock block, and the second inclined guide lock block of the unlocking trigger block, all pulled upward by the upward action of the pull rope, move upward together. During this process, the spring will also release its elastic force, causing the inclined guide groove and the bearing to press slightly. However, since the fourth actuating part acts directly on the second inclined guide lock, although the spring will increase the resistance of the upward operation, it will not cause the inclined guide lock assembly to get stuck in the slide groove, and the unlocking can still be completed.

[0054] Pull down to unlock: Please refer to Figure 13 As shown, when the controller pulls down, the unlocking trigger block also pulls down synchronously under the action of the follower. During the downward movement of the unlocking trigger block, the third actuating part will first contact the first inclined guide lock and drive the first inclined guide lock to move downward, causing the bearing to disengage from the inclined guide groove. This will prevent the first track mating surface of the first inclined guide lock block from pressing against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide lock block from pressing against the right end face of the inner side of the slide groove. Consequently, the inclined guide lock assembly will no longer be stuck in the slide groove, completing the unlocking. At the same time, under the upward pulling force of the pull rope, as the first inclined guide lock continues to move downward, the spring is compressed. The downward pulling force is transmitted to the first inclined guide lock through the third actuating part of the unlocking trigger block, and then to the self-locking trigger block through the spring. This will drive the counterweight and the pull rope connecting block to pull down together. The second inclined guide lock also moves downward under the action of the second actuating part of the self-locking trigger block.

[0055] In the second scenario, the upward tension on the pull rope at the load end is less than the downward tension on the pull rope at the operating end. In this case, the corresponding hovering self-locking, lift-to-unlock, and pull-down-to-unlock mechanisms are as follows:

[0056] Hover self-locking: Please refer to Figure 14As shown, after being lifted or pulled down to a certain position by the operator and then released, the pull rope connecting block, counterweight, and self-locking trigger block will move downwards. The second actuating part of the self-locking trigger block will drive the second inclined guide locking member downwards. At the same time, the spring will also release its elastic force, so that the second inclined guide locking member does not move downwards with the second inclined guide locking member. This causes the inclined guide groove to move downwards relative to the bearing. Under the inclined action of the inclined guide groove, the inclined guide groove is squeezed by the bearing, causing the first inclined guide locking member to move to the left and the second inclined guide locking member to move to the right. This causes the first track mating surface of the first inclined guide locking block to press and engage with the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide locking block to press and engage with the right end face of the inner side of the slide groove. As a result, the inclined guide locking assembly is stuck in the slide groove, forming a self-lock. The corresponding pull rope connecting block, counterweight, self-locking trigger block, unlocking trigger block, and follower also form a suspended state.

[0057] Pull up to unlock: Please refer to Figure 15 As shown, when the lever is lifted, the unlocking trigger block is also lifted synchronously under the action of the follower. During the upward movement of the unlocking trigger block, the fourth actuating part will first contact the second inclined guide lock and drive the second inclined guide lock to move upward, causing the inclined guide groove and the bearing to loosen slightly. This will prevent the first track mating surface of the first inclined guide lock block from pressing against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide lock block from pressing against the right end face of the inner side of the slide groove. Consequently, the inclined guide lock assembly will no longer be stuck in the slide groove, completing the unlocking. Then, as the unlocking trigger block continues to move upward, it contacts the self-locking trigger block, and the upward lifting force is transmitted to the self-locking trigger block, the first inclined guide lock block, the counterweight, and the pull rope connecting block, all moving upward together. During this process, the spring will also release its elastic force, causing the inclined guide groove and the bearing to press slightly. However, since the fourth actuating part acts directly on the second inclined guide lock, although the spring will increase the resistance of the upward operation, it will not cause the inclined guide lock assembly to get stuck in the slide groove, and the unlocking can still be completed.

[0058] Pull down to unlock: Please refer to Figure 16 As shown, when the controller pulls down, the unlocking trigger block also pulls down synchronously under the action of the follower. During the downward movement of the unlocking trigger block, the third actuating part will first contact the first inclined guide lock and drive the first inclined guide lock to move downward, causing the bearing to slightly loosen from the inclined guide groove. This will prevent the first track mating surface of the first inclined guide lock block from pressing against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide lock block from pressing against the right end face of the inner side of the slide groove. Consequently, the inclined guide lock assembly will no longer be stuck in the slide groove, completing the unlocking. At the same time, the self-locking trigger block, counterweight, and pull rope connecting block, under the action of overcoming the load end tension of the pull rope, carry the second inclined guide lock block downward together with the unlocking trigger block and the first inclined guide lock block.

[0059] As for the situation where the upward tension on the load end of the pull rope is equal to the downward tension on the operating end of the pull rope, this only exists at a specific position. In this case, the rope can be suspended at this position without the need for this inclined guide self-locking unlocking mechanism.

[0060] Example 2

[0061] Please refer to Figure 2 , Figure 3 , Figure 7 , Figures 17 to 23 As shown, the difference between this embodiment and Embodiment 1 is that the inclined guide first locking member 531 is fixedly connected to the self-locking trigger block 51. Specifically, the inclined guide first locking block 5311 has a first pin hole 5314 in the left-right direction, and the self-locking trigger block 51 has a second pin hole 512 in the left-right direction at a position corresponding to the first pin hole 5314. The inclined guide first locking member 531 and the self-locking trigger block 51 are fixedly connected by a pin 533 passing through the first pin hole 5314 and the second pin hole 512. Of course, the inclined guide first locking block 5311 and the self-locking trigger block 51 can also be designed as an integral structure. In addition, in this embodiment, the spring 518 is removed.

[0062] This embodiment addresses the case where counterweight 4 is not used, and the upward tension on the pull rope from the load end is greater than the downward tension on the pull rope from the operating end. In this case, the corresponding hovering self-locking, lifting to unlock, and pulling down to unlock are as follows:

[0063] Hover self-locking: Please refer to Figure 21 As shown, after being lifted or pulled down to a certain position by the manipulator and then released, the pull rope connects to the pull rope connecting block, the self-locking trigger block, and the first inclined guide locking member. The first inclined guide locking member moves upward relative to the second inclined guide locking member, causing the bearing to move upward as well. During the upward movement of the bearing, under the oblique action of the inclined guide groove, the bearing will squeeze the inclined guide groove, causing the first inclined guide locking member to move to the left and the second inclined guide locking member to move to the right. This causes the first track mating surface of the first inclined guide locking block to press against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide locking block to press against the right end face of the inner side of the slide groove. As a result, the inclined guide locking assembly is locked in the slide groove, forming a self-lock. The corresponding pull rope connecting block, self-locking trigger block, unlocking trigger block, and follower also enter a hovering state.

[0064] Pull up to unlock: Please refer to Figure 22As shown, when the operator lifts the lever, the unlocking trigger block also lifts synchronously under the action of the follower. During the upward movement of the unlocking trigger block, the fourth actuating part will first contact the second inclined guide lock and drive the second inclined guide lock to move upward, causing the inclined guide groove and the bearing to loosen slightly. This will prevent the first track mating surface of the first inclined guide lock block from pressing against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide lock block from pressing against the right end face of the inner side of the slide groove. Consequently, the inclined guide lock assembly will no longer be stuck in the slide groove, completing the unlocking. Then, the pull rope connecting block, the self-locking trigger block, and the first inclined guide lock block, which are pulled upward by the pull rope, and the unlocking trigger block and the second inclined guide lock block, which are lifted by the operator, will all move upward together.

[0065] Pull down to unlock: Please refer to Figure 23 As shown, when the controller pulls down, the unlocking trigger block also pulls down synchronously under the action of the follower. During the downward movement of the unlocking trigger block, the third actuating part will first contact the first inclined guide lock and drive the first inclined guide lock to move downward, causing the bearing to disengage from the inclined guide groove. This will prevent the first track mating surface of the first inclined guide lock block from pressing against the left end face of the inner side of the slide groove, and the second track mating surface of the second inclined guide lock block from pressing against the right end face of the inner side of the slide groove. Consequently, the inclined guide lock assembly will no longer be stuck in the slide groove, completing the unlocking. At the same time, under the upward pulling force of the pull rope, as the first inclined guide lock continues to move downward, the downward pulling force is transmitted to the first inclined guide lock and the self-locking trigger block through the third actuating part of the unlocking trigger block, thereby driving the pull rope connecting block to pull down together. The second inclined guide lock also moves downward under the action of the second actuating part of the self-locking trigger block.

[0066] The above embodiments should not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent conversion fall within the protection scope of the present invention.
