Description

Technical Field

[0001] The present invention relates to the technical field of glass-breaking ball launching devices, and in particular to a glass-breaking ball throwing system. Background Art

[0002] A glass-breaking device (or glass-breaking equipment) is a remote glass-breaking device specially used for throwing glass-breaking balls. It is widely used in the field of firefighting and rescue. At present, the structures of glass-breaking devices are diverse. For example, a pneumatic glass-breaking ball launching mechanism disclosed in Chinese patent CN211893653U is a type of glass-breaking device. The launching mechanism can be carried on a drone for use. The launching mechanism is specifically configured with a power chamber, a blocking structure, and a locking mechanism, etc. The power chamber and the blocking structure are adapted to each other. The blocking structure is movably arranged at one end of the power chamber for blocking and opening the power chamber; the locking mechanism and the blocking structure are adapted to each other for locking and unlocking the blocking structure; when the locking mechanism locks the blocking structure, the power chamber is closed, and the air pressure in the power chamber can be increased and reach the pressure required for throwing the glass-breaking ball; when it is necessary to throw the glass-breaking ball, the blocking structure is unlocked by the locking mechanism, and the blocking structure moves under the action of the air pressure in the power chamber and releases the high-pressure gas in the power chamber, and the high-pressure gas acts on the glass-breaking ball in the launching channel, thereby throwing the glass-breaking ball out by air pressure.

[0003] The glass-breaking ball launcher disclosed in Chinese patent CN211893653U is a first-generation product. In actual use, in order to facilitate repeated use and continuous throwing of glass-breaking balls, it is necessary to design the ball storage component to be replaceable. At the same time, after the ball storage component is installed, it is also necessary to ensure that the glass-breaking balls transported by the ball storage component can be accurately aligned with the guide cylinder and the valve core assembly to reduce the resistance during the throwing process and make the glass-breaking balls thrown farther. However, the existing glass-breaking ball launchers do not solve these technical problems. In particular, when the glass-breaking ball launcher is applied to a drone, the glass-breaking ball launcher is also required to realize the above functions with a simpler and more reliable structure to reduce the load of the drone. Therefore, how to more simply and reliably realize the rapid and high-precision matching of the guide cylinder, the ball storage component and the valve core assembly needs to be solved urgently. Summary of the invention

[0004] The first aspect of the present invention is to solve the above problems and provide a glass breaking ball throwing system, which can more simply and reliably realize the rapid and high-precision matching of the guide cylinder, the ball storage component and the valve core assembly, which is not only more convenient to use, but also has a better throwing effect. The main concept is:

[0005] A glass-breaking ball throwing system comprises a shell, a guide cylinder, a ball storage component, a valve core assembly and a power source, wherein a front cavity and a rear cavity which are interconnected are constructed in the shell, a first interface is constructed at the front end of the shell, the first interface is communicated with the front cavity, a second interface which is adapted to the ball storage component is also constructed on the side of the shell, the rear end of the guide cylinder is constructed to adapt to the first interface, the rear end of the guide cylinder is inserted into the front cavity via the first interface, a ball outlet and an air vent are constructed on the side of the upper end of the ball storage component, the ball outlet and the air vent are arranged opposite to each other, and the ball outlet and the air vent are respectively communicated with the ball bin in the ball storage component, and the top end of the ball storage component is detachably inserted into the front cavity of the shell via the second interface; the valve core assembly is arranged in the rear cavity, the ball outlet corresponds to the guide cylinder, the air vent corresponds to the valve core assembly, and the valve core assembly is used to control whether to release gas. In the present solution, the first interface and the second interface are configured on the shell so that the guide cylinder and the ball storage component can be positioned and assembled through the first interface and the second interface, so that after the guide cylinder is inserted into the shell through the first interface, it just connects with the ball storage component inserted from the second interface, which is very convenient and accurate. At the same time, when in use, when reassembling the ball storage component, the ball storage component can be just inserted between the guide cylinder and the valve core assembly, so that the ball outlet and the air vent correspond to the guide cylinder and the valve core assembly respectively, so that the guide cylinder, the ball storage component and the valve core assembly can be more simply and reliably realized. Rapid and high-precision matching. In addition, by arranging the ball outlet and the air vent in the ball storage component, the position between the ball outlet and the air vent is the excitation position, so that the glass-breaking balls can be lifted to the excitation position one by one with the help of the elastic member in the ball storage component, which can not only realize the effect of continuous launch more simply and accurately, work more stably, and be more convenient to replace, but also no additional lifting structure is required in the shell, which is conducive to a simpler structure of the entire system, especially suitable for use when mounted on a drone.

[0006] Preferably, the valve core assembly includes a gas storage component and a blocking structure adapted to each other, the gas storage component is provided with a gas chamber for accommodating gas, the front end of the gas storage component is provided with an exhaust channel, and the exhaust channel is connected to the gas chamber;

[0007] The rear end of the blocking structure is configured with a guide channel, the bottom of the guide channel is configured with an exhaust hole that penetrates the front end of the blocking structure, and a rod body adapted to the exhaust channel is arranged in the guide channel;

[0008] The blocking structure is movably arranged on the gas storage component, and the rod body is used to insert into and withdraw from the exhaust channel, so as to control whether to release the gas by moving the blocking structure.

[0009] Furthermore, a positioning channel is constructed in the rear cavity of the shell, and a positioning ring adapted to the positioning channel is constructed on the outer side of the gas storage component, and the gas storage component is positioned by the cooperation of the positioning ring and the positioning channel; the front cavity is cylindrical, the front cavity is coaxial with the positioning channel, and the rear end of the guide cylinder is configured to adapt to the front cavity, and the guide cylinder is coaxial with the front cavity. This ensures that the guide cylinder and the valve core assembly are strictly aligned, and the power loss during the throwing process is less, which is conducive to throwing the glass breaking ball farther.

[0010] Furthermore, a positioning portion is constructed in the rear cavity, and the air storage component is constructed with a step adapted to the positioning portion, and the axial installation position of the air storage component is positioned through the cooperation between the step and the positioning portion.

[0011] Furthermore, the rear end of the gas storage component is also provided with an interface for connecting the gas cylinder, the outer side of the gas storage component is also configured with an annular groove, the side wall of the shell is configured with a threaded hole, a fastener is connected in the threaded hole, and the fastener is inserted in the annular groove. Not only can the purpose of restraining the entire valve core assembly be achieved, but also when installing and removing the gas cylinder, the gas storage component, the interface and the gas cylinder sealing ring can rotate synchronously with the gas cylinder, thereby effectively preventing the gas cylinder and the interface from rotating relative to each other, protecting the gas cylinder sealing ring, not only facilitating a tighter seal and preventing leakage, but also effectively extending the service life of the gas cylinder sealing ring.

[0012] The second aspect of the present invention is to solve the problem that the existing valve core assembly is prone to air leakage. Further, the valve core assembly also includes a pressure ring, and the front end of the air storage component is configured with a connector for connecting the pressure ring, and the connector is configured with an exhaust channel;

[0013] The pressure ring is detachably connected to the connector, and the sealing ring of the adapting rod body is clamped between the pressure ring and the connector. The sealing ring is used to seal when the rod body is inserted into the exhaust channel. By configuring the pressure ring, the pressure ring is connected to the connector and the sealing ring of the adapting rod body is clamped between the pressure ring and the connector, not only can the sealing ring be used to achieve a better sealing effect between the rod body and the exhaust channel, and prevent the problem of air leakage between the rod body and the exhaust channel, so that the pressure in the air chamber is stable, and a better and more stable throwing effect can be achieved; not only is it not easy to have air leakage problems, but it can also meet the higher pressure gas storage requirements in the air chamber, which is conducive to achieving a longer throwing distance and a greater throwing force, and is more conducive to remote glass breaking; by detachably connecting the pressure ring to the connector, it is easier to install and replace the sealing ring, and there is no problem of difficulty in installation and replacement.

[0014] In order to reduce the casting resistance and make the valve core component move more smoothly relative to the air storage component, further, the front end of the air storage component is also configured with an extension portion, and the connector is connected to the extension portion; the outer diameter of the pressure ring is greater than the outer diameter of the extension portion;

[0015] The guide channel is configured to fit the pressure ring, and the blocking structure moves relative to the gas storage component through the cooperation between the guide channel and the pressure ring. In this solution, an extension portion is configured so that a reset spring is disposed outside the extension portion; the outer diameter of the pressure ring is configured to be larger than the outer diameter of the extension portion; and the inner diameter of the guide channel is configured to fit the pressure ring, so that the blocking structure can move relative to the gas storage component through the cooperation between the guide channel and the pressure ring under the action of air pressure. During the movement, the guide channel does not contact the outer side surface of the extension portion, but only uses the pressure ring to contact the blocking structure and guide the movement of the blocking structure. This can not only greatly reduce the contact area between the blocking structure and the gas storage component, but also effectively reduce the resistance during the movement of the blocking structure, so that the blocking structure moves more smoothly under the action of air pressure, with less power loss, which is conducive to throwing the glass-breaking ball farther.

[0016] Furthermore, the valve core assembly also includes a return spring, which is sleeved on the outside of the blocking structure, with one end of the return spring abutting against the housing and the other end abutting against the blocking structure, so as to drive the blocking structure to quickly return to its original position.

[0017] The third aspect of the present invention aims to solve the problems of improving the centering accuracy between the rod body and the guide channel, and improving the service life of the sealing ring. Furthermore, it also includes a tightening component, and the sealing structure is also constructed with a threaded hole and a positioning hole adapted to the tightening component, the threaded hole is connected to the positioning hole, the threaded hole passes through the front end of the sealing structure, and the positioning hole is connected to the guide channel and is coaxial; the rod body includes a rod portion and a head portion arranged at one end of the rod portion, the rod portion is adapted to the positioning hole, and the rod portion of the rod body is inserted into the guide channel through the positioning hole; the tightening component is threadedly connected to the threaded hole, and presses the rod body against the plugging portion. In this solution, the positioning hole can restrain and position the rod, and the rod can cooperate with the positioning hole to ensure the centering accuracy of the rod and the positioning hole, so that it can be easier to ensure that the rod is coaxial with the guide channel, and it is conducive to achieving a higher precision coaxial effect; by tightening the rod body with the tightening component, the relative position of the rod body and the guide channel will not be changed, so the centering accuracy of the rod and the guide channel will not be affected. The fixing process does not require the rotation of the rod body, so there is no need to process grooves on the rod, which can effectively solve the problem that the grooves can easily cause damage to the sealing ring in the power chamber, resulting in a significant reduction in the service life of the sealing ring. Compared with other designs, this design can not only more easily ensure the centering of the rod body and the guide channel, but also help to improve the centering accuracy of the rod body and the guide channel, not only making the assembly process simpler and more efficient, but also preventing the rod from misaligning with the guide channel, causing the blocking structure to become stuck or even stuck during movement. In addition, it is not easy to damage the sealing ring, ensuring the service life of the sealing ring.

[0018] Furthermore, it also includes an unlocking power and a locking mechanism adapted to the valve core assembly, wherein the unlocking power is connected to the locking mechanism through a transmission structure and is used to control the locking mechanism to lock and unlock the valve core assembly, which is conducive to realizing remote automatic control.

[0019] Compared with the prior art, the glass-breaking ball throwing system provided by the present invention can not only more simply and reliably achieve high-precision matching of the guide cylinder, the ball storage component and the valve core assembly, but also is more convenient to use and has a better throwing effect, and is particularly suitable for use when mounted on a drone.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0041] Example 1

[0042] like Figure 1 As shown, this embodiment provides a glass breaking ball throwing system, including a housing, a guide cylinder 2, a ball storage component 3, a valve core assembly and a power source, wherein Figure 1-Figure 3 As shown, the housing 1 includes a lower housing 10 and an upper housing 11 connected to the upper portion of the lower housing 10, wherein the lower housing 10 may be an integrally formed component. For example, in this embodiment, the lower housing 10 is a cylindrical structure, such as Figure 2 and Figure 3 As shown, it is an integrally formed component. The lower housing 10 is constructed with a front cavity 14 and a rear cavity 15 that are interconnected. The front cavity 14 is mainly used to install the ball storage component 3 of the guide cylinder 2, and the rear cavity 15 is mainly used to install the valve core assembly. The upper housing 11 can be spliced, and the upper housing 11 is constructed with an inner cavity to install the unlocking power 7, etc. Figure 2 and Figure 3 As shown, in the present embodiment, the side wall of the lower shell 10 is further provided with an opening, and a rack 81 is installed at the opening. The upper shell 11 is fastened to the rack 81 and / or the lower shell 10 by fasteners 61. A mounting structure 19 is also provided on the top of the upper shell 11. The mounting structure 19 can be a through hole, a threaded hole 47, etc. provided on the upper shell 11. In the present embodiment, the mounting structure 19 adopts a quick-release structure so as to utilize the quick-release structure to efficiently connect the drone.

[0043] like Figure 2 and Figure 3 As shown, the front end of the lower shell 10 is configured with a first interface 5712, and the first interface 5712 is connected to the front cavity 14; the rear end of the guide cylinder 2 is configured to adapt to the first interface 5712, so that when assembled, the rear end of the guide cylinder 2 can be inserted into the front cavity 14 through the first interface 5712; during implementation, the guide cylinder 2 is detachably connected to the lower shell 10, for example, in this embodiment, as Figure 2 and Figure 3As shown, it also includes a locking nut 22, and the side of the guide cylinder 2 is configured with an annular retaining ring 21. The rear end of the guide cylinder 2 is inserted into the first interface 5712, and the locking nut 22 is threadedly connected to the first interface 5712, and the annular retaining ring 21 is pressed against the end of the first interface 5712. Figure 2 and Figure 3 As shown, not only can the detachable connection of the guide cylinder 2 be achieved, but it is also beneficial to improve the connection strength between the guide cylinder 2 and the housing, making the guide cylinder 2 more secure.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the ball storage component 3 is constructed as a rod-shaped structure, and a ball bin for storing glass-breaking balls 92 is constructed in the ball storage component 3, and multiple glass-breaking balls 92 can be stored in the ball bin in a stacked manner. A ball holder for supporting the glass-breaking balls 92 is also provided in the ball bin of the ball storage component 3, and an elastic member (such as a spring) is provided between the ball holder and the bottom of the ball storage component 3, so that the elastic member can be used to continuously press the ball holder upward, so that the glass-breaking balls 92 can be pressed upward by the ball holder, so as to achieve the purpose of automatically pressing the glass-breaking balls 92 upward, so that the top glass-breaking balls 92 are just in the excitation position, which is conducive to more efficient continuous transportation and throwing of the glass-breaking balls 92. Figure 2 and Figure 3 As shown, the upper end of the ball storage component 3 is closed, and the side surface of the upper end of the ball storage component 3 is also constructed with a ball outlet 31 and an air vent 32, the ball outlet 31 and the air vent 32 are arranged opposite to each other, and the ball outlet 31 and the air vent 32 are respectively connected to the ball bin, the ball outlet 31 is used to input the glass-breaking ball 92, and the air vent is used for inserting the blocking structure 4 in the valve core assembly.

[0045] like Figure 2 As shown, the side of the lower housing 10 is also configured with a second interface 5713 adapted to the ball storage component 3. During assembly, the top end of the ball storage component 3 is inserted into the front cavity 14 of the lower housing 10 via the second interface 5713. After the ball storage component 3 is installed in place, as shown in FIG. Figure 2 and Figure 3 As shown, the ball storage component 3 adopts a snap-fit ​​structure to detachably restrain the ball storage component 3. When implemented, the snap-fit ​​structure can be implemented in the existing way, which will not be described here. When implemented, when the upper end of the ball storage component 3 abuts against the inner wall of the lower shell 10, the inner wall plays a role in positioning and limiting the ball storage component 3, so that the ball storage component 3 can be quickly assembled into place. At this time, the ball outlet 31 is directly opposite to the guide tube 2, as shown in FIG. Figure 2 and Figure 3 As shown, in order to be smoother and lower loss; in implementation, the rear end of the guide cylinder 2 can directly abut against the side wall of the ball storage component 3, which is more conducive to the coaxiality of the ball outlet 31 and the guide cylinder 2; Figure 2 and Figure 3 As shown, in the embodiment, the guide cylinder 2 and the ball storage component 3 are perpendicular to each other.

[0046] like Figure 2 , Figure 6 As shown, in this embodiment, the valve core assembly includes a return spring 6, an air storage component 5, and a plugging structure 4 movably arranged on the air storage component 5. During implementation, the valve core assembly can be an existing valve core assembly. For example, the valve core assembly can adopt the relevant structure in Chinese patent CN211893653U, which will not be described in detail here. In this embodiment, the valve core assembly can be arranged in the rear cavity 15 of the lower housing 10, such as Figure 2 and Figure 3 As shown, the ball outlet 31 of the ball storage component 3 faces the guide tube 2, and the vent 32 of the ball storage component 3 faces the valve core assembly. The inner diameter of the ball outlet 31 is smaller than the outer diameter of the front end of the blocking structure 4. At the same time, the inner diameter of the vent 32 is also smaller than the outer diameter of the front end of the blocking structure 4, so that after the valve core assembly is triggered, at least the front end of the blocking structure 4 can move forward and insert into the vent 32 of the ball storage component 3, which can not only throw the glass-breaking ball 92 in the ball storage component 3, but also use the blocking structure 4 to isolate the ball bin, so that the glass-breaking ball 92 below will not automatically rise to the excitation position. When the blocking structure 4 escapes from the vent 32 under the elastic force of the reset spring 6, the glass-breaking ball 92 at the top layer in the ball storage component 3 can automatically and continuously move upward under the action of the elastic member, and move to the top of the ball storage component 3 to reach the excitation position.

[0047] For example, in this embodiment, the guide cylinder 2 is coaxial with the ball outlet 31, the ball outlet 31 is coaxial with the wire cylinder, the ball outlet 31 is coaxial with the vent 32, and the vent 32 is coaxial with the valve core assembly, so that the guide cylinder 2, the ball outlet 31 and the valve core assembly can be strictly aligned. Figure 2 and Figure 3 As shown, it is beneficial to reduce resistance and increase the throwing distance of the glass-breaking ball 92.

[0048] For the convenience of control, in a more perfect embodiment, an unlocking power 7 and a locking mechanism are further included, wherein the unlocking power 7 is connected to the locking mechanism through a transmission mechanism, and the locking mechanism cooperates with the valve core assembly. When the locking mechanism is stuck in the valve core assembly, the valve core assembly is locked, and when the locking mechanism is driven by the unlocking power 7 and separated from the valve core assembly, the valve core assembly is unlocked, so that the glass breaking ball 92 is thrown out by air pressure to achieve the purpose of breaking glass. In implementation, the unlocking power 7 can be preferably arranged in the upper housing 11.

[0049] During implementation, the unlocking power 7 can be a motor, an electric cylinder, a steering gear, etc.

[0050] Example 2

[0051] In practical applications, leakage is likely to occur between the blocking structure 4 and the gas storage component 5, which not only easily leads to insufficient air pressure in the gas storage component 5, which greatly shortens the throwing force and throwing distance, affecting the glass breaking effect, but also easily leads to a reduction in the effective throwing times of the gas cylinder 91. To solve this technical problem, the main difference between the present embodiment 2 and the above-mentioned embodiment 1 is that, in the glass-breaking ball throwing system provided in the present embodiment, the valve core assembly includes a reset spring 6, a gas storage component 5 and a blocking structure 4 adapted to each other, wherein, as Figure 4-Figure 7 As shown, the gas storage component 5 is configured with an air chamber 54 for accommodating gas, the front end of the gas storage component 5 is configured with a rod-shaped extension portion 51, and the front end of the extension portion 51 is configured with a connector 52 for connecting the pressure ring 62. The extension portion 51 increases the length of the entire gas storage component 5, so that the gas storage component 5 can be moved into the ball storage component 3. An exhaust channel 53 is configured in the connector 52, one end of the exhaust channel 53 passes through the end of the connector 52, and the other end is connected to the air chamber 54, as shown in FIG. Figure 4-Figure 7 In practice, the outer side of the extension portion 51 can be configured as a cylindrical shape, and the exhaust passage 53 can be configured as a cylindrical passage so as to match the rod body 42. Figure 4-Figure 7 As shown, the rear end of the gas storage component 5 is also configured with an interface 57, which is connected to the air chamber 54 and is used to connect to the power source. For example, when the power source is a gas cylinder 91, the interface 57 is a sharp plug. In addition, the power source can also be an air pump, etc.

[0052] In implementation, the blocking structure 4 can be constructed as a cylindrical structure as a whole. As shown in the figure, the rear end of the blocking structure 4 is constructed with a guide channel 40, and the guide channel 40 does not penetrate the other end of the blocking structure 4. The bottom of the guide channel 40 is constructed with an exhaust hole 41 that penetrates the front end of the blocking structure 4, and the exhaust hole 41 is connected to the guide channel 40. Figure 4-Figure 7 As shown, the exhaust hole 41 is arranged at a position deviating from the center of the guide channel 40. A rod body 42 adapted to the exhaust channel 53 is also arranged in the guide channel 40. The rod body 42 is usually arranged at the center of the guide channel 40. Figure 4-Figure 7 As shown, during implementation, the rod body 42 is preferably constructed as a cylindrical structure, and the rod body 42 is coaxial with the guide channel 40. When in use, the rod body 42 is mainly used to insert and withdraw from the exhaust channel 53. On the one hand, the exhaust channel 53 can be blocked by inserting the exhaust channel 53, so that the gas in the air chamber 54 cannot pass through the exhaust channel 53, so that the air pressure in the air chamber 54 can rise to the required pressure, preparing for the subsequent throwing of the glass-breaking ball 92; on the other hand, the exhaust channel 53 can be opened by withdrawing from the exhaust channel 53, so that the gas in the air chamber 54 can be quickly discharged through the exhaust channel 53, and finally discharged from the front end of the blocking structure 4 through the exhaust hole 41, so that the glass-breaking ball 92 in the ball storage component 3 can be thrown out by air pressure.

[0053] In this embodiment, a sealing ring 6355 and a pressure ring 62 adapted to the connector 52 are also included. Figure 6 and Figure 7 As shown, the sealing ring 6355 can preferably be an O-ring 6355, and the cross-section of the sealing ring 6355 can preferably be circular, which is not only conducive to achieving a better sealing effect, but also allows the rod body 42 to pass through the sealing ring 6355 more smoothly without the problem of jamming.

[0054] like Figure 6 and Figure 7 As shown, during assembly, the pressure ring 62 is threadedly connected to the connector 52, and the sealing ring 6355 of the adapting rod body 42 is clamped between the pressure ring 62 and the connector 52, which is convenient for installing and replacing the sealing ring 6355 and can reliably constrain and fix the sealing ring 6355. Figure 6 and Figure 7 As shown, there is no need to machine the ring groove inside, which can simplify the structure and reduce the cost, and facilitate the restraint and fixation of the sealing ring 6355.

[0055] During implementation, the rod body 42 can be installed on the blocking structure 4 by means of fasteners 61 such as bolts or screws, and can also be integrally formed with the blocking structure 4 .

[0056] Due to functional requirements, the extension portion 51 is usually configured to be longer. When the extension portion 51 and the guide channel 40 cooperate to guide the rod body 42, the contact area between the extension portion 51 and the guide channel 40 is large, resulting in large resistance and power loss during the movement of the rod body 42, which is not conducive to improving the utilization rate of the pneumatic power. To solve this technical problem, in a further embodiment, the pressure ring 62 is constructed as a rotating body structure, such as Figure 6 and Figure 7 As shown, the outer diameter of the pressure ring 62 is larger than the outer diameter of the extension portion 51; at the same time, the guide channel 40 is constructed to adapt to the pressure ring 62, and the guide channel 40 can contact the pressure ring 62 and can move relative to the pressure ring 62, so that the guide channel 40 does not contact the outer side surface of the extension portion 51, and only uses the pressure ring 62 to contact the rod body 42 and guide the movement of the rod body 42, which can greatly reduce the contact area between the rod body 42 and the air storage component 5, and effectively reduce the resistance during the movement of the rod body 42, so that the movement of the rod body 42 under the action of air pressure is smoother, with less power loss, thereby improving the utilization rate of air pressure power and facilitating the throwing of the glass-breaking ball 92 farther.

[0057] In a further embodiment, the pressure ring 62 can preferably be made of copper, that is, the pressure ring 62 is made of copper, so as to further reduce the friction between the rod body 42 and the pressure ring 62, which can protect the rod body 42, improve the service life and ensure the movement accuracy; it can also make the movement of the rod body 42 smoother and the power loss less, which is conducive to throwing the glass-breaking ball 92 farther.

[0058] During use, when the rod body 42 is separated from the sealing ring 6355, the exhaust channel 53 is connected to the exhaust hole 41 via the guide channel 40. When the rod body 42 is inserted into the sealing ring 6355, the exhaust channel 53 is disconnected from the exhaust hole 41 and exhaust cannot be discharged.

[0059] In order to ensure that the valve core assembly is strictly aligned with the guide cylinder 2, in a further embodiment, as shown in FIG. Figure 2 , Figure 3 and Figure 7 As shown, a positioning channel 16 is constructed in the rear cavity 15 of the lower shell 10, and at the same time, a positioning ring 56 adapted to the positioning channel 16 is constructed on the outer side of the air storage component 5, and the outer diameter of the positioning ring 56 is less than or equal to the positioning channel 16. During assembly, the air storage component 5 is positioned by the cooperation of the positioning ring 56 and the positioning channel 16; at the same time, the front cavity 14 is constructed into a cylindrical shape, and the front cavity 14 and the positioning channel 16 can be strictly aligned through machining; the rear end of the guide cylinder 2 is constructed to adapt to the front cavity 14, so that the guide cylinder 2 can be positioned through the cooperation of the two, so that the guide cylinder 2 and the front cavity 14 are strictly aligned, thereby ensuring that the guide cylinder 2 and the valve core assembly are strictly aligned.

[0060] like Figure 2 , Figure 3 and Figure 7 As shown, the positioning channel 16 runs through the rear end of the lower housing 10 so that the valve core assembly can be assembled from the rear end; in this embodiment, a positioning portion 18 is also constructed in the rear cavity 15, and accordingly, the gas storage component 5 is constructed with a step adapted to the positioning portion 18, and the axial installation position of the gas storage component 5 is positioned and limited by the step and the positioning portion 18. In addition, an annular groove is also constructed on the outer side of the gas storage component 5, and a threaded hole 47 is constructed on the side wall of the lower housing 10. When the gas storage component 5 is installed in place, the threaded hole 47 is opposite to the annular groove, so that a fastener 61 can be set in the threaded hole 47, and the end of the fastener 61 can be inserted into the annular groove to fix the gas storage component 5, thereby achieving the purpose of constraining the entire valve core assembly. With this design, the valve core assembly can rotate relative to the housing.

[0061] In implementation, when the power source is a gas cylinder 91, as Figure 2As shown, it also includes a sheath 9, which is threadedly connected to the shell and presses the gas cylinder 91 against the interface 57, so that the gas cylinder 91 is connected to the air chamber 54; a gas cylinder 91 sealing ring 6355 is arranged between the gas cylinder 91 and the interface 57, and the gas storage component 5 adopts the above-mentioned rotatable installation method. When installing and disassembling the gas cylinder 91, the gas storage component 5, the interface 57 and the gas cylinder 91 sealing ring 6355 can rotate synchronously with the gas cylinder 91, thereby effectively preventing the gas cylinder 91 and the interface 57 from rotating relative to each other, and protecting the gas cylinder 91 sealing ring 6355, which is not only conducive to tighter sealing and less prone to leakage problems, but also can effectively extend the service life of the gas cylinder 91 sealing ring 6355.

[0062] During implementation, the entire gas storage component 5 can be constructed as a rotating body structure.

[0063] Example 3

[0064] In the existing valve core assembly, the rod body 42 is constructed with a threaded hole 47. The rod body 42 is usually installed in the sliding sleeve of the valve core assembly through a fastener 61 that is adapted to the threaded hole 47. However, since the fastener 61 and the rod body 42 are threadedly connected, it is difficult to ensure that the rod body 42 and the sliding sleeve are coaxial. Not only does it take a lot of time to adjust the position of the rod body 42 during the assembly process, resulting in very low assembly efficiency, but it is also easy for the sealing structure 4 to get stuck or even get stuck during the movement relative to the air storage component 5 due to the non-coaxiality of the rod body 42 and the sliding sleeve. In addition, since the end of the rod body 42 is also processed with a groove, the edge of the groove is relatively sharp. During the movement of the sealing structure 4 relative to the power chamber, the groove at the end of the rod body 42 is very likely to cause damage to the sealing ring 6355 in the power chamber, resulting in a significant reduction in the service life of the sealing ring 6355. In order to solve this technical problem, the main difference between this embodiment 3 and the above-mentioned embodiments 1 or 2 is that the glass-breaking ball throwing system provided in this embodiment also includes a tightening component 45, such as Figure 8-Figure 10 As shown, the outer side of the tightening component 45 is configured with an external thread, and one end of the tightening component 45 is also configured with a tightening portion adapted to a tightening tool. During implementation, the tightening portion may be a straight groove, a cross groove, or an inner hexagonal groove, etc. For example, Fig.10 As shown, the tightening portion uses an inner hexagonal groove.

[0065] like Figure 8-Figure 10 As shown, the blocking structure 4 is also configured with a threaded hole 47 and a positioning hole 48 adapted to the top tightening member 45, the threaded hole 47 is connected to the positioning hole 48, the threaded hole 47 passes through the front end of the blocking structure 4, and the positioning hole 48 is connected to the guide channel 40; at the same time, the rod body 42 is configured to include a rod portion 43 and a head portion 44 provided at one end of the rod portion 43, as shown in FIG. Figure 8-Figure 10As shown, the shape of the positioning hole 48 is adapted to the shape of the rod 43, and the shape of the rod 43 is adapted to the shape of the guide channel 40. In a preferred embodiment, the guide channel 40 is generally a cylindrical channel. Therefore, the rod 43 can be a cylindrical rod adapted thereto. Accordingly, the positioning hole 48 is a circular hole adapted to the rod 43. Figure 8-Figure 10 As shown. In practice, the positioning hole 48 is coaxial with the guide channel 40. In practice, the positioning hole 48 and the guide channel 40 can be easily coaxial by machining, and it is conducive to achieving a coaxial effect with higher precision, so as to ensure that the rod 43 is strictly aligned with the guide channel 40, so that the movement process of the blocking structure 4 is smoother and the resistance is smaller. Similarly, in practice, the inner diameter of the threaded hole 47 needs to be larger than the inner diameter of the positioning hole 48 to accommodate the head 44. Preferably, the threaded hole 47 is coaxial with the positioning hole 48, as shown in FIG. Figure 8-Figure 10 As shown, the threaded hole 47 can be easily made coaxial (or called centering, which will not be described in detail later) with the positioning hole 48 through machining, and the coaxial effect can be effectively guaranteed, which is not only easier to process and shape, but also easier to assemble and disassemble.

[0066] In this embodiment, the size of the head 44 in the rod body 42 is larger than the size of the rod portion 43 in the rod body 42, and needs to be smaller than the inner diameter of the threaded hole 47, so that the head 44 in the rod body 42 can be stuck in the threaded hole 47. Figure 8-Figure 10 shown.

[0067] In implementation, the shape and size of the rod 43 are configured to fit the positioning hole 48. For example, in this embodiment, the rod 43 is a cylindrical rod. Figure 8-Figure 10 As shown, the outer diameter of the rod portion 43 can be configured to be equal to the inner diameter of the positioning hole 48, so that during assembly, the rod portion 43 of the rod body 42 can be inserted into the guide channel 40 through the positioning hole 48, as shown in FIG. Figure 8-Figure 10 As shown, a high-precision centering effect is automatically achieved through the cooperation between the rod portion 43 and the positioning hole 48; in addition, during implementation, the outer diameter of the rod portion 43 can be constructed to be slightly smaller than the inner diameter of the positioning hole 48, so that during assembly, the rod portion 43 of the rod body 42 can be inserted into the guide channel 40 through the positioning hole 48, and the required centering accuracy can be achieved through the cooperation between the rod portion 43 and the positioning hole 48, without repeatedly adjusting the position of the rod body 42, making the assembly process very convenient and efficient.

[0068] In implementation, the end of the rod 43 away from the head 44 can be constructed as a streamlined structure, such as a hemispherical structure, a semi-elliptical structure, or a bullet head structure, etc. Figure 8-Figure 10 As shown, not only can the resistance be effectively reduced, thereby effectively reducing the pressure loss of the high-pressure gas, but also the sealing ring 6355 will not be damaged during the movement, thereby ensuring the service life of the sealing ring 6355.

[0069] The function of the pressing component 45 is to press (or press) the rod body 42 to fix the rod body 42. During assembly, the rod portion 43 of the rod body 42 can be inserted into the guide channel 40 through the positioning hole 48, and the head portion 44 of the rod body 42 can be accommodated in the threaded hole 47; the pressing component 45 is threadedly connected to the threaded hole 47 and presses the head portion 44 of the rod body 42, thereby pressing the rod body 42 to the plugging portion 44, thereby fixing the rod body 42 to the blocking structure 4. In this design, the positioning hole 48 can restrain and position the rod 43, and the centering accuracy of the rod 43 and the positioning hole 48 can be ensured by the cooperation between the rod 43 and the positioning hole 48, so that it can be easier to ensure that the rod 43 and the guide channel 40 are coaxial, and it is conducive to achieving a higher precision coaxial effect; the rod body 42 is tightened by the tightening component 45, and the relative position of the rod body 42 and the guide channel 40 will not be changed, thereby not affecting the centering accuracy of the rod 43 and the guide channel 40. There is no need to rotate the rod body 42 during the fixing process, so there is no need to process a groove on the rod 43, thereby effectively solving the problem that the groove can easily cause damage to the sealing ring 6355 in the power chamber, resulting in a greatly reduced service life of the sealing ring 6355. Compared with other designs, this design can not only more easily ensure the alignment of the rod body 42 and the guide channel 40, but also is conducive to improving the alignment accuracy of the rod body 42 and the guide channel 40, which not only makes the assembly process simpler and more efficient, but also prevents the blocking structure 4 from getting stuck or even stuck during movement due to the misalignment between the rod 43 and the guide channel 40. In addition, it is not easy to damage the sealing ring 6355, thereby ensuring the service life of the sealing ring 6355.

[0070] Example 4

[0071] In the existing glass-breaking ball throwing system that uses air pressure to drive the glass-breaking ball 92, after the valve core assembly is unlocked, the exhaust and excitation process is very fast, so that the resetting process of the valve core assembly is also very fast. However, in the existing glass-breaking ball throwing system, the locking mechanism is usually connected to the transmission mechanism, and the resetting process of the transmission mechanism usually has a lag, and the resetting speed is slow, resulting in a large difference between the resetting speed of the valve core assembly and the resetting speed of the locking mechanism, which not only affects the overall resetting efficiency, but also has the phenomenon of inaccurate resetting, seriously affecting the stability and reliability of the resetting process, and even easily causing the locking mechanism to fail to get stuck in the valve core assembly. To solve this technical problem, the main difference between this embodiment and the above-mentioned embodiment is that in the glass-breaking ball throwing system provided by this embodiment, the locking mechanism includes a frame 81, a lever member 84, and an elastic member, such as Fig.11 and Fig.12As shown, the transmission mechanism includes a transmission member 75, wherein the frame 81 plays a bearing role and the frame 81 is connected to the housing. The transmission member 75 is mainly used for transmission. The transmission member 75 can be lifted and restrained on the frame 81, so that the transmission member 75 can move up and down relative to the frame 81 and the lever member 84. In implementation, the frame 81 is also provided with a guide portion 82 adapted to the transmission member 75, as shown in FIG. Fig.11 and Fig.12 As shown, the transmission member 75 can be movably constrained by the guide part 82 through the cooperation with the guide part 82, and the guide part 82 is used to constrain the transmission member 75 and guide the movement of the transmission member 75, so as to ensure that the transmission member 75 can run more accurately along the predetermined track, which can not only ensure that the transmission member 75 is always matched with the lever member 84, but also make the transmission member 75 and the lever member 84 form a more stable and reliable cooperation. In implementation, the guide part 82 can be a guide cylinder 2, a guide groove or a guide hole, etc.

[0072] like Fig.11 and Fig.12 As shown, in this embodiment, the two ends of the lever member 84 are respectively the first end and the second end. At the same time, the lever member 84 is also configured with a hinge hole 85, and the hinge hole 85 is configured between the first end and the second end. Fig.11 and Fig.12 As shown, in this embodiment, the hinge hole 85 is not a round hole. Fig.11 and Fig.12 To facilitate the cooperation with the blocking structure 4, the first end of the lever member 84 is configured with a locking portion 86 adapted to the valve core assembly. In practice, the locking portion 86 may include a downwardly protruding block or a rotatably mounted locking wheel, such as Fig.11 and Fig.12 Correspondingly, the outer side of the blocking structure 4 is configured with a latching groove 49 adapted to the locking portion 86 .

[0073] like Fig.11 and Fig.12 As shown, the frame 81 is provided with a shaft 83, which can be a pin, a rotating shaft, a pin, etc. During assembly, the lever member 84 is sleeved on the shaft 83 through the hinge hole 85. Since the hinge hole 85 is a bar hole, the lever member 84 can rotate relative to the shaft 83 and can also move relative to the shaft 83. The transmission member 75 is provided on one side of the lever member 84, as shown in FIG. Fig.11 and Fig.12 As shown in FIG. 1 , when the lever member 84 moves in a direction close to the transmission member 75, the second end of the lever member 84 can move to the bottom of the transmission member 75, as shown in FIG. Fig.11 and Fig.12As shown, when the transmission member 75 moves downward, it can squeeze the second end of the lever member 84, thereby realizing the transmission coordination between the transmission member 75 and the lever member 84. When the second end of the lever member 84 is pressed downward, the first end of the lever member 84 is synchronously lifted up by utilizing the lever principle, so that the locking portion 86 is disengaged from the valve core assembly, thereby achieving the purpose of unlocking the valve core assembly.

[0074] like Fig.11 and Fig.12 As shown, in this embodiment, the elastic member is mainly used to press the first end of the lever member 84 downward, so that the locking cooperation between the locking portion 86 and the blocking structure 4 is more stable and reliable, and there will be no automatic disengagement and accidental triggering. In implementation, the elastic member can be a torsion spring, a compression spring, a tension spring 88, etc. In this embodiment, the elastic member is a tension spring 88, one end of which is connected to the lever member 84, such as Fig.11 and Fig.12 As shown, it can be connected to the second end or a position close to the second end; the other end of the tension spring 88 is connected to the frame 81, so that the second end of the lever member 84 can be pulled upward by the tension spring 88, that is, the tension spring 88 is used to drive the lever member 84 to rotate clockwise, so that the first end of the lever member 84 can be pressed downward by utilizing the lever principle, so that the locking portion 86 of the lever member 84 can be inserted into the blocking structure 4 and can be stably inserted, thereby achieving the purpose of more stably locking the blocking structure 4.

[0075] In this embodiment, the unlocking power 7 can be arranged on the frame 81, and the unlocking power 7 is in transmission connection with the transmission member 75, so as to drive the transmission member 75 to rise and fall.

[0076] The locking mechanism provided in this embodiment adopts a bar hole as the structure of the hinge hole 85, so that the lever member 84 can not only rotate relative to the shaft 83, so as to use the lever to move away from the unlocking blocking structure 4 to achieve the purpose of triggering, but also the lever member 84 can move relative to the shaft 83, so as to control whether the lever member 84 and the transmission member 75 can transmit power by changing the position of the lever member 84. When the air chamber 54 is not inflated, the blocking structure 4 is pressed against the air storage component 5 or the housing under the action of the return spring 6. At this time, the locking portion 86 of the lever member 84 is stuck in the slot 49, and the lever member 84 is at a position away from the transmission member 75, such as Fig.11 As shown, the transmission member 75 and the lever member 84 cannot transmit. When the air chamber 54 of the pneumatic transmitter is inflated, the blocking structure 4 and the lever member 84 can be synchronously moved a distance in the direction close to the transmission member 75 under the action of the air pressure until the hinge hole 85 abuts against the shaft 83. At this time, the second end of the lever member 84 can move to the bottom of the transmission member 75, as shown in FIG. Fig.12As shown, it can form a transmission cooperation with the transmission member 75, and the lever member 84 is in the triggering position. When triggered, the unlocking power 7 drives the transmission member 75 to move downward, so that the transmission member 75 can contact and squeeze the second end of the lever member 84, so that the locking portion 86 is disengaged from the slot 49 of the blocking structure 4, thereby achieving the purpose of unlocking the blocking structure 4 and triggering. After being triggered, the blocking structure 4 moves in the opposite direction and resets under the action of the reset spring 6. Since the lever member 84 is not directly connected to the transmission member 75, and at the same time, with the cooperation of the elastic member, the lever member 84 can be quickly reset, the reset process of the transmission member 75 and the lever member 84 do not affect each other, so that the lever member 84 can be reset faster, and the lever member 84 moves in a direction away from the transmission member 75, so that the second end of the lever member 84 leaves the bottom of the transmission member 75, and the locking portion 86 remains in a downwardly pressed state under the action of the elastic member; at the same time, the reset process of the blocking structure 4 is used to drive the locking portion 86 to automatically re-enter the blocking structure 4, as shown in FIG. Fig.11 As shown, the valve core assembly and the locking mechanism can form a more efficient and stable reset cooperation. Compared with the prior art, the transmission member 75 and the lever member 84 in this design are not directly connected. With such a design, during the reset process, the reset process of the transmission member 75 is completely unrelated to the reset process of the lever member 84, and the reset process of the lever member 84 is associated and coordinated with the reset process of the blocking structure 4. Not only does it make the lever member 84 cooperate with the blocking structure 4 faster during the reset process, which is beneficial to improving the reset efficiency, but it can also improve the stability and reliability of the reset process, ensuring that the lever member 84 can be smoothly inserted into the blocking structure 4.

[0077] In addition, in a more complete solution, an observation window can be constructed on the shell, and the observation window corresponds to the blocking structure 4. By checking the position of the blocking structure 4 through the observation window, it can be determined whether there is pressure in the air chamber 54, making the use process more convenient and safer.

[0078] Example 5

[0079] In actual use, it is found that the transmission member 75 is easy to interfere with the lever member 84 during the process of rising and resetting, so there is a risk that the transmission member 75 cannot be smoothly reset or even gets stuck. In order to solve this technical problem, the main difference between this embodiment 5 and the above-mentioned embodiment 4 is that in the glass-breaking ball throwing system provided by this embodiment, the lower end of the transmission member 75 is rotatably provided with a trigger head 79, such as Fig.13 and Fig.14As shown, for example, the trigger head 79 can be rotatably arranged on the transmission member 75 through a hinge shaft. At the same time, the transmission member 75 is provided with a limiting portion 78, and the limiting portion 78 is located above the trigger head 79. A return member is provided between the trigger head 79 and the transmission member 75. During implementation, the return member can be a torsion spring, a tension spring 88, etc. In this embodiment, the return member is a torsion spring, which can be sleeved on the hinge shaft. Initially, the trigger head 79 is upwardly pressed against the limiting portion 78 under the action of the torsion return member. Fig.13 and Fig.14 As shown, at this time, one end of the trigger head 79 facing the lever member 84 (the right end in the figure) protrudes from the side wall of the transmission member 75, so that when the transmission member 75 moves downward, the protruding trigger head 79 can be used to press downward the lever member 84 located on one side of the transmission member 75 to achieve transmission cooperation; during the process of the transmission member 75 rising and resetting, if interference occurs between the trigger head 79 and the lever member 84, the trigger head 79 can rotate downward relative to the transmission member 75 under the action of the squeezing force of the lever member 84, as shown in FIG. Fig.14 As shown, the trigger head 79 rotates in a direction away from the limiting portion 78 so that the transmission member 75 can rise smoothly, and the trigger head 79 can automatically reset under the action of the torsion spring after passing through the lever member 84, thereby effectively solving the problem of the trigger head 79 and the lever member 84 interfering and getting stuck during the resetting process of the transmission member 75, and improving stability and reliability.

[0080] During implementation, the limiting portion 78 may be a limiting block, a limiting step, etc., which are arranged on the transmission member 75 .

[0081] like Fig.13 and Fig.14 As shown, in a more perfect embodiment, the right end of the trigger head 79 is also constructed with a first guide surface 791, which can contact the lever member 84 during the resetting process and can guide and reduce the rotation angle of the trigger head 79. Even if the transmission member 75 interferes with the lever member 84 during the resetting process, it can smoothly pass through the lever member 84 to achieve rapid resetting, which is conducive to a more compact structure and a smaller volume. In implementation, the first guide surface 791 can be an inclined surface constructed on the right end of the trigger head 79, such as Fig.13 and Fig.14 As shown in FIG. 1 , when the trigger head 79 abuts against the first limit portion 78, the inclined surface is inclined in the vertical direction. Accordingly, the second end of the lever member 84 is also configured with a second guide surface 87 adapted to the first guide surface 791, as shown in FIG. Fig.13 and Fig.14 As shown, the second guide surface 87 is an inclined surface inclined to the vertical direction, so that through the cooperation between the first guide surface 791 and the second guide surface 87, a better guiding effect can be achieved and the interference problem can be better resolved.

[0082] Example 6

[0083] The main difference between the present embodiment 7 and the above-mentioned embodiments 5 or 6 is that in the glass-breaking ball throwing system provided in the present embodiment, the unlocking power 7 adopts a motor or a steering gear, and the unlocking power 7 is connected to the transmission member 75 through a connecting rod 72, so as to drive the transmission member 75 to rise and fall through the connecting rod 72. Specifically, in the present embodiment, a connecting shaft 76 is provided on the top of the transmission member 75, such as Figure 15-18 As shown, the connecting shaft 76 can be perpendicular to the length direction of the transmission member 75; at the same time, the connecting rod 72 is configured with a constraint portion, such as Figure 15-18 As shown, the connecting shaft 76 is constrained by the constraining part, and the connecting rod 72 can move relative to the transmission member 75 and can rotate relative to the transmission member 75 to prevent the connecting rod 72 and the transmission member 75 from interfering or even getting stuck during the transmission process. When in use, the unlocking power 7 can drive the connecting rod 72 to swing, and the swing of the connecting rod 72 is used to drive the transmission member 75 to rise and fall. Combined with the cooperation of the transmission shaft and the constraining part, when implemented, only the connecting rod 72 needs to be arranged between the power source and the transmission member 75 to achieve the purpose of driving the transmission member 75 to rise and fall, thereby effectively simplifying the transmission mechanism and reducing the space occupied by the entire transmission mechanism, which is conducive to a smaller volume and a more compact structure of the entire glass breaker.

[0084] In implementation, the constraint portion may be a bar hole constructed on the connecting rod 72, and the connecting shaft 76 may be inserted into the bar hole; for example, the constraint portion may be a bar-shaped bayonet 73 constructed on the end of the connecting rod 72, such as Figure 15-18 As shown, the connecting shaft 76 is inserted into the strip bayonet 73, which is not only convenient for installation and disassembly, but also can drive the transmission member 75 to rise and fall through the cooperation between the strip bayonet 73 and the connecting shaft 76. During this process, the connecting rod 72 can both move and rotate relative to the transmission member 75, thereby avoiding interference in the transmission process and achieving smooth transmission.

[0085] In practice, the connecting shaft 76 is also provided with a roller 77. Fig.15 As shown, the friction and wear can be reduced by using the roller 77 to contact the constraint.

[0086] In order to improve the matching accuracy and transmission accuracy between the transmission member 75 and the lever member 84, in a further embodiment, a flange 71 is further included, such as Figure 16-Figure 18 As shown, at least two flange holes 711 are provided in the circumferential direction of the flange 71, and the unlocking power 7 is connected to the flange 71 for driving the flange 71 to rotate. For example, the flange 71 can be connected to the output shaft of the unlocking power 7 through a fastener 61. A connecting plate 731 is provided at one end of the connecting rod 72, such as Figure 16-Figure 18As shown, the connection plate 731 is configured with connection holes adapted to the flange holes 711 along the circumferential direction. When the flange holes 711 are circular holes, the connection holes can be arc-shaped strip holes 74, such as Figure 16-Figure 18 As shown; when the flange hole 711 adopts an arc-shaped bar hole 74, the connecting hole can be a circular hole or an arc-shaped bar hole 74; during assembly, the connecting plate 731 can be fixed to the flange 71 by a fastener 61 that is adapted to the connecting hole and the flange hole 711 for installation and disassembly; and by constructing the flange hole 711 or the connecting hole as an arc-shaped bar hole 74, and the flange hole 711 and the connecting hole are distributed along the circumferential direction, therefore, during assembly, the connecting plate 731 can be rotated relative to the flange 71, so that the pitch angle of the connecting rod 72 can be adjusted by rotating the connecting plate 731, thereby effectively adjusting the initial height position of the transmission member 75, which is not only very convenient and has better versatility, but also can solve the transmission error caused by manufacturing error and assembly error, which is conducive to achieving higher-precision transmission, especially can improve the matching accuracy and transmission accuracy between the transmission member 75 and the lever member 84.

[0087] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
