Description

Technical Field

[0001] This utility model relates to the field of optical imaging technology, and in particular to a ranging module and a sight. Background Technology

[0002] A scope provides a clear, magnified image, allowing the user to observe and identify distant targets, thereby improving aiming accuracy. To quickly and accurately obtain target distance information and improve shooting accuracy, scopes are often integrated with rangefinder modules.

[0003] The rangefinding module itself has a certain degree of deviation during assembly, and there is also a certain degree of deviation when it is installed into the main scope barrel. This causes a misalignment between the optical axis of the rangefinding module and the optical axis of the scope's mechanism, resulting in a misalignment between the ranging point and the aiming point, which seriously affects the aiming accuracy of the scope. However, existing rangefinding modules lack adjustment and correction functions, and usually only allow for fine-tuning of the position of the rangefinding module during assembly, with limited adjustment and correction capabilities. Utility Model Content

[0004] In view of this, the present invention provides a rangefinding module and a sight with adjustment and correction functions.

[0005] On one hand, this application provides a ranging module, including a ranging component and an adjustment component. The adjustment component includes an adjustment base, a first adjustment member, and a second adjustment member. The ranging component is mounted on the adjustment base, and the first adjustment member and the second adjustment member are respectively connected to the adjustment base. The first adjustment member is used to swing the adjustment base in a first direction, and the second adjustment member is used to swing the adjustment base in a second direction to adjust the ranging optical path direction of the ranging component, wherein the first direction and the second direction are perpendicular to each other.

[0006] On the other hand, this application also provides a sight, including a rangefinding module as described above and a main scope barrel, wherein the rangefinding module is mounted on the outer periphery of the main scope barrel.

[0007] The ranging module provided by this utility model includes an adjusting base, a first adjusting member, and a second adjusting member. The first adjusting member can swing the adjusting base in a first direction and drive the ranging component to swing in the first direction. The second adjusting member can swing the adjusting base in a second direction and drive the ranging component to swing in the second direction, thereby adjusting the ranging optical path direction of the ranging component. This enables the ranging module itself to have an adjustment and correction function. Moreover, the adjusting member can swing the ranging component in two different directions, making the adjustment of the ranging component more flexible so as to adjust the ranging component to the correct position and eliminate deviations caused during assembly.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0011] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0012] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0013] Please see Figures 1 to 8 This utility model provides a sight 100, including a main scope barrel 10 and a rangefinder module 12 mounted on the main scope barrel 10. The rangefinder module 12 includes a rangefinder component 14 and an adjustment component 16. The rangefinder component 14 emits a laser and measures the distance between itself and a target object, assisting the user in aiming at the target and improving aiming accuracy. The adjustment component 16 drives the rangefinder component 14 to move relative to the main scope barrel 10, thereby adjusting the relative position of the rangefinder component 14. When the position of the rangefinder component 14 changes, its range-finding optical path direction, i.e., the laser direction, also changes accordingly, thus achieving an adjustment and correction effect.

[0014] Please see Figure 3 The adjustment assembly 16 includes an adjustment base 18, a first adjustment member 20, and a second adjustment member 22. The ranging assembly 14 is mounted on the adjustment base 18. The first adjustment member 20 and the second adjustment member 22 are respectively connected to the adjustment base 18. The first adjustment member 20 is used to swing the adjustment base 18 in the first direction Z, thereby causing the ranging assembly 14 to swing in the first direction Z, thus adjusting the position of the ranging assembly 14 in the first direction Z. The second adjustment member 22 is used to swing the adjustment base 18 in the second direction Y, thereby causing the ranging assembly 14 to swing in the second direction Y, thus adjusting the position of the ranging assembly 14 in the second direction. When the position of the ranging assembly 14 changes, its ranging optical path direction also changes, thereby adjusting the ranging optical path direction of the ranging assembly 14. The first direction Z and the second direction Y are two mutually perpendicular directions. The ranging module 12 can adjust the ranging optical path direction of the ranging assembly 14 through the adjustment assembly 16, so that the ranging module 12 itself has an adjustment and correction function to eliminate deviations that occur during the assembly process. Furthermore, the adjustment component 16 allows the rangefinding component 14 to swing in two different directions, making the adjustment of the position of the rangefinding component 14 more flexible, so as to adjust the rangefinding component 14 to the correct position, so as to better eliminate the deviations that occur during its own assembly and when it is installed on the main lens barrel 10.

[0015] Understandably, the first adjusting member 20 and the second adjusting member 22 drive the adjusting base 18 to swing. This can mean driving the entire adjusting base 18 to swing or driving a part of the adjusting base 18 to swing, as long as it can drive the ranging component 14 to swing in the corresponding direction.

[0016] In an optional example, the correct position of the ranging component 14 means that the laser generated by the ranging component 14 forms a light spot in the user's field of view, and the position of the photoelectric sensor changes when the direction of its optical axis changes. The movement components inside the main lens barrel 10 form a crosshair in the field of view. When the adjustment component 16 drives the ranging component 14 to move, the position of the light spot relative to the crosshair changes. When the light spot coincides with the center of the crosshair, the position of the ranging component 14 is the correct position, ensuring that the ranging point and the aiming point coincide.

[0017] The first direction Z and the second direction Y are perpendicular to the optical axis X of the main scope 10. That is, any two of the first direction Z, the second direction Y and the optical axis X are perpendicular. When the user holds the firearm equipped with the scope 100 in a standing position, the firearm is in front of the user and the scope 100 is above the firearm. The optical axis X of the main scope 10 is in the front-back direction relative to the user, the first direction Z is in the up-down direction relative to the user, and the second direction Y is in the left-right direction relative to the user.

[0018] Understandably, the range measuring module 12 is installed on the main lens barrel 10, which can mean that the range measuring module 12 is installed inside the main lens barrel 10 or that the range measuring module 12 is installed on the outside of the main lens barrel 10.

[0019] In an optional example, the rangefinding module 12 is mounted on the outer periphery of the main lens barrel 10. This not only reduces assembly difficulty and avoids the rangefinding module 12 occupying internal space of the main lens barrel 10, but also ensures that the user is not affected by the main lens barrel 10 during adjustment and calibration using the adjustment component 16. The rangefinding module 12 does not need to be removed from the main lens barrel 10 during adjustment; the user can adjust and calibrate independently using the adjustment component 16, making it convenient for the user.

[0020] Along the axial direction of the main scope barrel 10, the rangefinding module 12 can be positioned in the middle of the main scope barrel 10, which makes the center of gravity distribution of the scope 100 more reasonable and avoids the problem of the scope 100 being heavy at one end and light at the other. Alternatively, along the axial direction of the main scope barrel 10, the rangefinding module 12 can also be positioned close to the eyepiece section of the main scope barrel 10, that is, the rangefinding module 12 is closer to the eyepiece end in the axial direction than the objective lens end, so as to shorten the distance between the rangefinding module and the user during use and facilitate the user's adjustment operation. The objective lens and the eyepiece are respectively installed at both ends of the main scope barrel 10. The objective lens end refers to the end of the main scope barrel 10 where the objective lens is installed, and the eyepiece end refers to the end of the main scope barrel 10 where the eyepiece is installed.

[0021] Please see Figure 2 and Figure 6In one embodiment, the ranging module 12 further includes a ranging housing 24, which is located outside the main lens barrel 10. The adjusting base 18 and the ranging component 14 are both located inside the ranging housing 24 and can rotate inside the ranging housing 24 to protect the ranging component 14 and the adjusting base 18.

[0022] A light-emitting port 26 is provided through the ranging housing 24, corresponding to the ranging component 14. The laser generated by the ranging component 14 can pass through the light-emitting port 26, preventing the ranging component 14 from blocking the laser. The orientation of the light-emitting port 26 is consistent with the optical axis direction X of the main lens barrel 10, and the first direction Z and the second direction Y are both perpendicular to the orientation of the light-emitting port 26.

[0023] One end of both the first adjusting member 20 and the second adjusting member 22 is exposed outside the ranging housing 24, forming an operating section 28 for user operation, facilitating adjustment. Optionally, the operating section 28 is provided with a tool interface for use with external adjustment tools such as screwdrivers. The user can adjust the position of the ranging assembly 14 by using the external adjustment tool in conjunction with the first adjusting member 20 and the second adjusting member 22. The tool interface can be a slotted slot, a Phillips head slot, a hexagonal hole, a triangular hole, etc.

[0024] Please see Figure 6 and Figure 7 In one embodiment, the adjustment base 18 includes a first adjustment bracket 30 and a second adjustment bracket 32 ​​arranged along a first direction Z, with a movable space between them, allowing relative movement between them in the first direction Z. The second adjustment bracket 30 and the second adjustment bracket 32 ​​remain relatively fixed in the second direction Y, preventing relative movement between them in the second direction Y. The ranging component 14 is fixedly mounted on the first adjustment bracket 30, and the second adjustment bracket 32 ​​is located on the side of the first adjustment bracket 30 away from the ranging component 14, and the second adjustment bracket 32 ​​is rotatably connected to the ranging housing 24.

[0025] The first adjusting member 20 is connected to the first adjusting bracket 30 and is used to drive the first adjusting bracket 30 to swing relative to the second adjusting bracket 32 ​​in the first direction Z, thereby causing the ranging component 14 to move together and changing the position of the ranging component 14 in the first direction Z. The swing axis of the first adjusting bracket 30 in the first direction Z is perpendicular to the first direction Z and extends along the second direction Y. The second adjusting member 22 is connected to the second adjusting bracket 32 ​​and is used to drive the second adjusting bracket 32 ​​to swing relative to the ranging housing 24 in the second direction Y, thereby causing the first adjusting bracket 30 and the ranging component 14 to move together and changing the position of the ranging component 14 in the second direction Y. The swing axis of the second adjusting bracket 32 ​​in the second direction Y is perpendicular to the second direction Y and extends along the first direction Z. By setting the adjustment base 18 to include a first adjustment bracket 30 and a second adjustment bracket 32, and the first adjustment bracket 30 and the second adjustment bracket 32 ​​can generate relative movement in the first direction Z, but cannot generate relative movement in the second direction Y, the adjustment of the ranging component 14 in the first direction Z and the adjustment in the second direction Y will not affect each other, thus taking into account the adjustment of the ranging component 14 in the first direction Z and the second direction Y.

[0026] It should be noted that rotation can be circular motion or oscillation. In circular motion, the geometric center of an object lies on the axis of rotation, and the trajectory is typically a complete circle; the position of the object's geometric center does not change with the circular motion. In contrast, in oscillation, the geometric center of an object does not lie on the axis of oscillation, and the trajectory is typically an arc; the position of the object's geometric center changes with the oscillation. Of course, oscillation is not necessarily achieved through rotation. For example, deformation can cause a localized part of the object to reciprocate in one direction, thus creating an oscillation effect. In this application, the ranging component 14 can oscillate in the first direction Z under the action of the first adjusting member 20, and can oscillate in the second direction Y under the action of the second adjusting member 22.

[0027] Understandably, the first adjusting bracket 30 swings relative to the second adjusting bracket 32 ​​in the first direction Z. This swinging effect can be achieved by rotating to move closer to or away from the second adjusting bracket 32, or by deforming. For example, the first adjusting bracket 30 can be configured as an elastic sheet structure. When the first adjusting member 20 presses the first adjusting bracket 30 along the first direction Z, the first adjusting bracket 30 can deform, thereby moving closer to the second adjusting bracket 32. When the pressing force of the first adjusting member 20 on the first adjusting bracket 30 decreases, the first adjusting bracket 30 returns to its initial state under its own elastic force, thereby moving away from the second adjusting bracket 32, thus creating a swinging effect in the first direction Z. Similarly, the second adjusting bracket 32 ​​swings in the second direction Y, which can be achieved by rotation or deformation, and will not be elaborated further here.

[0028] Please see Figure 6 In one embodiment, one end of the first adjusting bracket 30 is rotatably connected to the second adjusting bracket 32. Optionally, one end of the first adjusting bracket 30 is rotatably connected to the second adjusting bracket 32 ​​via a rotating shaft 34. The first adjusting member 20 can drive the first adjusting bracket 30 to swing relative to the second adjusting bracket 32 ​​in the first direction Z around the rotating shaft 34. That is, the swing axis of the first adjusting bracket 30 in the first direction Z is the central axis of the rotating shaft 34. The axial direction of the rotating shaft 34 is perpendicular to the first direction Z and extends along the second direction Y, thereby enabling the first adjusting bracket 30 and the second adjusting bracket 32 ​​to form a rotational engagement effect in the first direction Z via the rotating shaft 34, and a relatively fixed effect in the second direction Y.

[0029] The first adjusting bracket 30 has a first pivot portion 36 at one end, which extends along the first direction Z. The second adjusting bracket 32 ​​has two second pivot portions 38, which are spaced apart and opposite to each other. Along the second direction Y, the first pivot portion 36 is located between the two second pivot portions 38 and is rotatably connected to them via a rotating shaft 34. That is, both ends of the rotating shaft 34 protrude from the outer side of the first pivot portion 36 and are connected to the two second pivot portions 38 respectively, thereby realizing the rotatable connection between the first adjusting bracket 30 and the second adjusting bracket 32. By using the vertically extending first pivot portion 36 to rotatably connect with the second adjusting bracket 32, a certain distance can be maintained between the first adjusting bracket 30 and the second adjusting bracket 32 ​​in the first direction Z, so as to form a space for the first adjusting bracket 30 to move.

[0030] The first adjusting member 20 is located on one side of the first adjusting bracket 30 in the first direction Z, with one end of the first adjusting member 20 abutting against the first adjusting bracket 30 and the other end exposed outside the ranging housing 24 to form an operating part 28. When the first adjusting member 30 moves along the first direction Z, it abuts against the first adjusting bracket 30 and causes the first adjusting bracket 30 to move toward or away from the second adjusting bracket 32, thereby achieving the swinging effect of the first adjusting bracket 30 in the first direction Z.

[0031] The first adjusting member 20 can move along the first direction Z by forming a sliding fit between the first adjusting member 20 and the ranging housing 24 in the first direction Z, allowing the first adjusting member 20 to slide along the first direction Z. In this case, one end of the first adjusting member 20 can be directly fixedly connected to the first adjusting bracket 30, or it can abut against the first adjusting bracket 30. Alternatively, the first adjusting member 20 can form a threaded fit between one end of the first adjusting member 20 and the end of the ranging housing 24 in the first direction Z, with one end of the first adjusting member 20 abutting against the first adjusting bracket 30. When the first adjusting member 20 rotates in its circumferential direction, it will also move in the first direction Z.

[0032] like Figure 6 As shown, an elastic reset member 40 is provided between the first adjusting bracket 30 and the second adjusting bracket 32, and the elastic reset member 40 is at least partially located within the movable space. The elastic reset member 40 is elastic, and when it deforms, it generates an elastic force. This elastic force acts on the first adjusting bracket 30 to provide the first adjusting bracket 30 with an elastic force that moves it away from the second adjusting bracket 32, so that the first adjusting bracket 30 has a reset effect.

[0033] When the first adjusting member 20 moves toward the first adjusting bracket 30, it compresses the first adjusting bracket 30, causing it to rotate toward the second adjusting bracket 32 ​​and compress the elastic reset member 40. The elastic reset member 40 is compressed and deformed, generating elastic force. When the first adjusting member 20 moves away from the first adjusting bracket 30, the first adjusting bracket 30 moves away from the second adjusting bracket 32 ​​under the elastic force of the elastic reset member 40. For example, the elastic reset member 40 is a spring disposed between the first adjusting bracket 30 and the second adjusting bracket 32, and this spring is in a compressed state.

[0034] Understandably, the first adjusting member 20 can move closer to or further away from the first adjusting bracket 30 by sliding or by rotating, as long as it can generate displacement relative to the ranging housing 24 in the first direction Z. In an optional example, the first adjusting member 20 is threadedly engaged with the ranging housing 24. When the first adjusting member 20 rotates, it can move in the first direction, causing the first adjusting bracket 30 to move closer to or further away from the second adjusting bracket 32. When the first adjusting member 20 is tightened, it moves closer to the first adjusting bracket 30, thereby compressing the elastic reset member 40 and causing the first adjusting bracket 30 to move closer to the second adjusting bracket 32. When the first adjusting member 20 is loosened, it moves away from the first adjusting bracket 30. Under the elastic force of the elastic reset member 40, the first adjusting bracket 30 moves away from the second adjusting bracket 32. Therefore, the oscillation of the ranging assembly 14 in the first direction Z can be controlled by tightening or loosening the first adjusting member 20, making the adjustment operation simple.

[0035] Optionally, the first adjusting bracket 30 has a plate-like structure, with one end rotatably connected to the second adjusting bracket 32 ​​via a rotating shaft 34, and the other end protruding from the ranging component 14. The first adjusting member 20 abuts against the other end of the first adjusting bracket 30, and the elastic reset member 40 is located between the other end of the first adjusting bracket 30 and the second adjusting bracket 32.

[0036] Please see Figure 6 and Figure 8 In one embodiment, the second adjusting member 22 is located on one side of the second adjusting bracket 32 ​​in the first direction Z, that is, the first adjusting member 20 and the second adjusting member 22 are located on the same side of the adjusting base 18. The end of the second adjusting member 22 near the second adjusting bracket 32 ​​is provided with a transmission member 42, and the end away from the second adjusting bracket 32 ​​is rotatably engaged with the ranging housing 24. When the second adjusting member 22 rotates relative to the ranging housing 24, it drives the transmission member 42 to move together.

[0037] The transmission member 42 is eccentrically positioned relative to the central axis of the second adjusting member 22, meaning that the central axis of the transmission member 42 is spaced a certain distance from the central axis of the first adjusting member 20. The second adjusting bracket 32 ​​has a groove 44, through which the transmission member 42 movably passes. Along the extending direction of the groove 44, the length of the groove 44 is greater than the length of the transmission member 42, thus allowing the transmission member 42 to slide within the groove 44. Because the transmission member 42 is eccentrically positioned relative to the second adjusting member 22, the position of the transmission member 42 changes when the second adjusting member 22 rotates. Since the transmission member 32 movably passes through the groove 44, when it rotates with the second adjusting member 22, it presses against the groove wall of the groove 44 and pushes the second adjusting bracket 32 ​​to swing in the second direction Y.

[0038] Optionally, the second adjusting member 22 has a plate-like structure, with one end of the groove 44 extending to the outer edge of the second adjusting bracket 32, forming a U-shaped groove. The second adjusting bracket 32 ​​partially protrudes from the outside of the first adjusting bracket 30, and the groove 44 is located on the portion of the second adjusting bracket 32 ​​that protrudes from the outside of the first adjusting bracket 30. One end of the second adjusting member 22 passes through the outside of the ranging assembly 14 and the first adjusting bracket 30, and allows the transmission member 42 to be inserted into the groove 44.

[0039] The ranging housing 24 has a support plate 46 inside. The second adjusting bracket 32 ​​is rotatably mounted on the support plate 46 via a connector 48, thereby indirectly rotatably connecting to the ranging housing 24. The second adjusting member 22 can drive the second adjusting bracket 32 ​​to swing relative to the ranging housing 24 in the second direction Y around the connector 48. That is, the swing axis of the second adjusting bracket 32 ​​in the second direction Y is the central axis of the connector 48.

[0040] The transmission component 42 and the connecting component 48 are spaced apart. The connecting component 48 is located on the side of the ranging component 14 in the optical axis direction X of the main lens barrel 10, and the transmission component 42 is located on the side of the ranging component 14 in the second direction Y. The connecting component 48 is closer to the central axis of the ranging component 14 than the transmission component 42. The transmission component 42 pushes the second adjusting bracket 32 ​​to swing around the connecting component 48.

[0041] The transmission component 42 and the second adjusting component 22 can be integrally formed or connected separately. Please refer to [link / reference]. Figure 8 In an optional example, the transmission member 42 and the second adjusting member 22 are separately connected. The second adjusting member 22 has a connecting hole 50 at one end near the second adjusting bracket 32. The connecting hole 50 is opposite to and communicates with the groove 44, and is eccentrically positioned relative to the central axis of the second adjusting member 22. The groove 44 penetrates the second adjusting bracket 32 ​​along the first direction Z. One end of the transmission member 42 passes through the groove 44 from the side of the second adjusting bracket 32 ​​away from the first adjusting bracket 30 and inserts into the connecting hole 50, thus fixing the transmission member 42 and the second adjusting member 22 together and creating an eccentric effect. The other end of the transmission member 42 is located on the side of the second adjusting bracket 32 ​​away from the first adjusting bracket 30 and cannot pass through the groove 44, thereby creating a limiting effect on the second adjusting member 22 in the first direction Z, restricting the second adjusting member 22 from moving away from the second adjusting bracket 32.

[0042] For example, the transmission component 42 is a bolt, the size of the bolt head is larger than the size of the shank, the shank passes through the groove 44 and is inserted into the connecting hole 50, and the head is located on the side of the second adjusting bracket 32 ​​away from the first adjusting bracket 30. The head is too large to pass through the groove 44, thus forming a limiting effect in the first direction Z.

[0043] The second adjusting member 22 has a protrusion 52 at one end near the second adjusting bracket 32. The protrusion 52 extends in a direction perpendicular to the first direction Z, that is, the protrusion 52 protrudes from the circumferential side of the second adjusting member 22 in a direction perpendicular to the first direction Z. This extension direction includes, but is not limited to, the second direction Y. The connecting hole 50 is at least partially located on the protrusion 52. By providing a protrusion 52 at one end of the second adjusting member 22, a local thickening effect can be formed, which facilitates the setting of an eccentric connecting hole 50 on the second adjusting member 22.

[0044] Please see Figures 3 to 5 In one embodiment, the ranging housing 24 includes a housing body 54 and a cover plate 56. One end of the housing body 54 is connected to the main lens barrel 10, and the other end is provided with the cover plate 56. The housing body 54 and the cover plate 56 cooperate to form a receiving space, in which the ranging component 14 and the adjustment base 18 are housed, and the ranging component 14 is located between the cover plate 56 and the adjustment base 18. The first adjustment member 20 and the second adjustment member 22 are located on one side of the adjustment base 18 in the first direction Z, and the ends of the first adjustment member 20 and the second adjustment member 22 away from the adjustment base 18 are both located on the outside of the cover plate 56, thereby forming an operating part 28 exposed on the ranging housing 24 for the user to perform adjustment operations. That is, the operating part 28 is formed on the outside of the cover plate 56. Optionally, the cover plate 56 is pressed and fixed to the housing body 54 by a pressure ring 57, which is threadedly engaged with one end of the housing body 54.

[0045] The first adjusting member 20 is threadedly engaged with the cover plate 56. Therefore, when the first adjusting member 20 rotates relative to the cover plate 56 in its circumferential direction, it will move in the first direction Z to move closer to or further away from the cover plate 56. The second adjusting member 22 is rotatably connected to the cover plate 56. When it rotates relative to the cover plate 56, it drives the transmission member 42 to rotate together, thereby pushing the second adjusting bracket 32 ​​to rotate. However, the second adjusting member 22 is not threadedly engaged with the cover plate 56, and the second adjusting member 22 will not move in the first direction Z when it rotates in its circumferential direction.

[0046] Sealing rings 58 are provided between the first adjusting member 20 and the cover plate 56, and between the second adjusting member 22 and the cover plate 56. The cover plate 56 has two through holes for the first adjusting member 20 and the second adjusting member 22 to pass through, with the sealing rings 58 located within the corresponding through holes. The inner and outer surfaces of the sealing ring 58 located between the first adjusting member 20 and the cover plate 56 are tightly fitted with the walls of the first adjusting member 20 and the corresponding through hole, respectively. The inner and outer surfaces of the sealing ring 58 located between the second adjusting member 22 and the cover plate 56 are tightly fitted with the walls of the second adjusting member 22 and the other through hole, respectively. When the first adjusting member 20 and the second adjusting member 22 move relative to the cover plate 56 in the first direction Z, a certain amount of friction is generated between the sealing rings 58 and the first adjusting member 20 and the second adjusting member 22. Friction can, to some extent, prevent the first adjusting member 20 and the second adjusting member 22 from moving relative to the cover plate 56 in the first direction Z, thus preventing the first adjusting member 20 and the second adjusting member 22 from moving relative to the cover plate 56 in the first direction Z due to the impact force when firing the gun, which would cause the ranging component 14 to deviate from the correct position after calibration.

[0047] It should be noted that friction hinders the movement of the first adjusting member 20 in the first direction Z, which means that it increases the difficulty of the first adjusting member 20 moving in the first direction Z, not that it cannot move in the first direction Z.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model.
