Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of aiming scopes, and in particular relates to a mechanism for quickly flipping a doubler Background Art
[0002] An aiming scope (also known as a red dot gunsight) is an optical instrument used to improve shooting accuracy and is usually installed on a device, a telescope, a stage light, or other shooting weapons. Its core function is to help the user capture the target more quickly and improve the hit rate.
[0003] A doubler (also known as a magnification lens) is an optical instrument with a magnification factor and can usually be held by hand or connected in series behind the eyepiece of a red dot sight and installed on a device or other shooting equipment. Its core function is to magnify the field of view to achieve accurate shooting and clear observation.
[0004] When the red dot sight and the doubler are installed in series on a device or other shooting equipment, when switching between using and not using the doubler, the user needs to be able to quickly flip the doubler without leaving the holding position (forearm). The existing switching mechanism requires both hands to cooperate to adjust, which is not only inconvenient, but also changes the aiming reference. After switching, re-aiming is required, and due to the cumulative error of the axial clearance caused by vibration during frequent shooting, the switching angle error occurs. Summary of the Invention

[0010] A teleconverter, the bottom of which is fixed on a flipping mechanism. Through the flipping mechanism, the teleconverter can be flipped into two states. One is that the teleconverter is flipped and placed on a bracket seat and is on the same optical axis as a red dot sight. The other is that the teleconverter is flipped to avoid the red dot sight and is located at the side of the bracket seat. The flipping mechanism forces the teleconverter to flip and move within an active included angle range;
[0011] A limiting mechanism, which is arranged between the bracket seat and the flipping mechanism and is used to limit the flipping of the flipping mechanism within the active included angle range;
[0012] A clearance elimination mechanism, which is arranged at one end of the flipping mechanism and is used to eliminate the axial mating clearance of the flipping mechanism, so that during the flipping adjustment process, there is only a single rotational degree of freedom.
[0013] In the present invention, a further embodiment is that the flipping mechanism is arranged on the left side of the bracket seat below the red dot sight. When the teleconverter flips to avoid the red dot sight, the teleconverter and the flipping mechanism are on the same side.
[0014] In the present invention, a further embodiment is that the inside of the support seat is hollowed out, the bottom of the red dot sight is fixed on the support seat, and the flipping mechanism rotates through the support seat.
[0015] In the present invention, a further embodiment is that the handle includes a barrel part and a handle part. The barrel part is sleeved on one end of a rotating shaft, and an oblong slot is opened on the barrel part. A locking screw is fixed on the rotating shaft. When the barrel part is sleeved on one end of the rotating shaft, the locking screw passes through the oblong slot for limit fitting, so that the handle can have a certain movement stroke in the axial direction of the rotating shaft.
[0016] In the present invention, a further embodiment is that the limiting mechanism includes a limiting rod. One end of the limiting rod is locked and fixed on the side of the bracket seat, and a limiting column located below the rotating shaft is arranged at the other end of the limiting rod. A limiting slot extending at a right angle is opened on the outside of the barrel part. When the barrel part is sleeved on one end of the rotating shaft, the limiting column is in positioning fit with the limiting slot. The cooperation of the locking screw and the oblong slot and the cooperation of the limiting column and the limiting slot jointly force the handle to be able to move a certain stroke in the axial direction of the rotating shaft and drive the rotating shaft to rotate within the active included angle range.
[0017] In the present invention, a further embodiment is that a mechanism for quickly flipping a teleconverter further includes a spring-back mechanism. The spring-back mechanism includes a bolt and a compression spring. The compression spring passes through the center of the barrel part and is locked and connected to one end inside the rotating shaft.

[0020] In the present invention, a further implementation scheme is that a mechanism for quickly flipping the magnifying mirror also includes a mounting mechanism, which includes an adjusting rod, an adjusting nut, a pressure block and an elastic element. The pressure block is movably arranged on one side of the bottom of the bracket seat, and the adjusting rod can be rotated to pass through the pressure block and the other side of the bracket seat. The pressure block and the adjusting rod are threadedly connected, the adjusting nut is fixed to the end of the adjusting rod, and the elastic element is sleeved on the adjusting rod and abuts between the pressure block and the adjusting nut.
[0021] The beneficial effects of the present invention are:
[0022] The mechanism of the rapid flipping telescope can be installed on a Picatinny rail or other rails through a bracket seat, and the flipping mechanism can be used to realize the rapid flipping of the telescope into position within the range of the active angle. When the telescope needs to be involved, the original aiming position is kept unchanged. After the handle is moved into position, the rebound mechanism automatically pushes the handle out so that the handle is positioned by the limiting mechanism. At this time, the telescope is also flipped to be on the same optical axis as the red dot sight. In this state, the telescope magnification can be used to participate in the red dot aiming. When the telescope is not needed, the handle is pushed first and then bent in the opposite direction to make the telescope flip in the opposite direction to avoid the red dot sight. Therefore, the flipping mechanism can achieve the effect of rapid flipping of the telescope with one hand without the need to move the holding hand away from the original position.
[0023] The clearance elimination mechanism eliminates the axial fit clearance of the rotating shaft, so that during the flipping adjustment process, there is only a single rotational degree of freedom, and no axial activity error is caused by the fit clearance, which not only makes the adjustment process more precise, but also makes the flipping process natural and smooth.
[0024] The clearance elimination mechanism and the rebound mechanism work together, and the clearance elimination mechanism forms a "preload" state, so that the rebound force of the compression spring is no longer absorbed by the axial clearance, so that the shaft only retains the rotational freedom required by the design, eliminating the cumulative error of the axial clearance caused by vibration during shooting.

[0036] Embodiment 1: This embodiment provides a mechanism for quickly flipping a teleconverter, including a red dot sight 2 and a teleconverter 3. The mechanism for quickly flipping the teleconverter further includes:
[0037] A bracket base 1, the bottom of which can be mounted on a rail, and the top of the bracket base 1 is used to provide support. Specifically, the bracket base 1 can be fixed to a Picatinny rail or other rails, and the specific mounting structure will be mentioned later.
[0038] Among them, the red dot sight 2 is fixedly arranged at the rear side near the human body on the top of the bracket base 1. The red dot sight 2 provides a red dot aiming area. This part is the existing red dot sight 2 and will not be elaborated in this embodiment. In particular, when the object to be aimed at is relatively far away, there may be phenomena such as inaccurate aiming or unclear observation.
[0039] In particular, this embodiment includes a flipping mechanism. The flipping mechanism is rotatably adjustable and arranged on the bracket base 1. The flipping mechanism is arranged through the length direction of the bracket base 1. The flipping mechanism is rotatably connected to the bracket base 1, and the flipping mechanism is a manually adjustable mechanical structure.
[0040] This embodiment further includes a magnifier 3. Among them, the bottom of the magnifier 3 is fixed to the flipping mechanism. Therefore, the flipping mechanism is rotatably adjustable relative to the bracket base 1 and is fixed relative to the magnifier 3. So when manually rotating and adjusting the flipping mechanism, the magnifier 3 can be flipped and controlled.
[0041] According to the above, in this embodiment, the magnifier 3 can be adjusted to two states through the flipping mechanism. One is that the magnifier 3 is flipped and placed on the bracket base 1 on the same optical axis as the red dot sight 2. In this state, the magnifier 3 participates in the magnification factor, so as to facilitate aiming at distant objects and can also increase the clarity of observation.
[0042] The other is that the magnifier 3 is flipped to avoid the red dot sight 2 and is located on the side of the bracket base 1. In this state, the magnifier 3 does not participate in the work and does not affect the work of the red dot sight 2. Further, the flipping mechanism forces the magnifier 3 to flip and move within the active angle range (the active angle in this embodiment is actually an angle range of 0 - 90°). This angle range is the most reasonable and is also the fastest to control. Define the position when the magnifier 3 participates in the work as 0°. Flipping 90° makes the magnifier 3 just avoid the red dot sight 2. It can be flipped to the position in one step at 0° and 90°. Through the flipping mechanism, the effect of quickly flipping the magnifier 3 with one hand is achieved without affecting the original aiming position.
[0043] In this embodiment, a limiting mechanism is further included. The limiting mechanism is arranged between the bracket base 1 and the flipping mechanism and is used to limit the flipping of the flipping mechanism within the active angle range. The limiting mechanism can accurately limit the manual control in place situation of the flipping mechanism. With the cooperation of the limiting mechanism, when the magnifier 3 needs to participate in the work, then manually control the flipping mechanism to rotate and it will be automatically pushed to the position of another state by the limiting mechanism, achieving accurate flipping in place; when the magnifier 3 does not participate in the work, first press one end of the flipping mechanism in place and then rotate it reversely by 90° in place, automatically making the magnifier 3 flip to avoid the red dot sight 2.
[0044] In this embodiment, specifically, the flipping mechanism is arranged on the left side of the bracket base 1 below the red dot sight 2. When the magnifier 3 is flipped to avoid the red dot sight 2, the magnifier 3 is on the same side as the flipping mechanism. When in use, the red dot sight 2 is close to the human body side. Defined from the human body side, the left side of the human body is the left side in this embodiment. Therefore, when it is found during the aiming process that the magnifier 3 is needed, there is no need to change the aiming posture and position, and only the flipping mechanism can be controlled by the left hand, compared with the cumbersome process of the traditional additional pretending to install the magnifier 3.
[0045] In this embodiment, further, a support base 10 is formed on the top of the bracket base 1. The inside of the support base 10 is hollowed out. The bottom of the red dot sight 2 is fixed on the support base 10. The flipping mechanism rotates through the support base 10. The design of hollowing out the bottom of the support base 10 can not only achieve light weight, but also improve the heat dissipation effect of the red dot sight 2.
[0046] In this embodiment, further, the flipping mechanism includes a rotating shaft 4, a handle 5 and a torsion spring 6. The rotating shaft 4 rotates through the support base 10 and its two ends respectively extend from the front and rear sides of the bracket base 1. The bottom of the magnifier 3 is locked to the rotating shaft 4 through a fixing plate. There is a gap between the magnifier 3 and the red dot sight 2. The handle 5 is sleeved on one end of the rotating shaft 4 close to the red dot sight 2 side. The torsion spring 6 is sleeved on the rotating shaft 4 and is located between the support bases 10. The middle part of the torsion spring 6 is pressed and fixed to the rotating shaft 4 by a screw 7. By rotating the rotating shaft 4, the torsion spring 6 is forced to generate a tension elastic force centered on the rotating shaft 4. When the magnifier 3 is not working, the torsion spring 6 is in a relaxed state and there is no elastic potential energy. When the rotating shaft 4 is rotated by the handle 5, the torsion spring 6 generates a tension elastic force and generates elastic potential energy. When the state adjustment without the participation of the magnifier 3 is required, first push the handle 5 in place, and the rotating shaft 4 is automatically driven to flip back under the elastic force of the torsion spring 6, which not only has a certain damping effect, but also is convenient for quick return.
[0047] In this embodiment, further, the handle 5 includes a cylindrical part 50 and a handle part 51. The cylindrical part 50 is through. The cylindrical part 50 is sleeved on one end of the rotating shaft 4. A long circular groove 500 is opened on the cylindrical part 50. A locking screw 40 is fixed on the rotating shaft 4. When the cylindrical part 50 is sleeved on one end of the rotating shaft 4, the locking screw 40 passes through the long circular groove 500 for limit cooperation, so that the handle 5 can have a certain movement stroke in the axial direction of the rotating shaft 4. The cooperation between the handle 5 and the rotating shaft 4 through the locking screw 40 and the long circular groove 500 is coordinated. During the adjustment process, there is a certain movement stroke of the handle 5 relative to the axial direction of the rotating shaft 4, that is, the cooperation stroke of the locking screw 40 and the long circular groove 500. Through the cooperation, it can also prevent the handle 5 from falling off the rotating shaft 4.
[0048] In this embodiment, further, the limiting mechanism includes a limiting rod 8. One end of the limiting rod 8 is locked and fixed to the side of the support base 1. The other end of the limiting rod 8 is provided with a limiting post 80 located below the rotating shaft 4. A limiting groove 501 extending at a right angle is formed outside the cylindrical portion 50. When the cylindrical portion 50 is sleeved on one end of the rotating shaft 4, the limiting post 80 is in positioning cooperation with the limiting groove 501. The cooperation of the locking screw 40 and the oblong groove 500 and the cooperation of the limiting post 80 and the limiting groove 501 jointly force the handle 5 to move a certain stroke in the axial direction of the rotating shaft 4 and drive the rotating shaft 4 to rotate within the movable angle range. The limiting mechanism and the flipping mechanism act synergistically. When the teleconverter 3 needs to be used, the left hand rotates the handle 5. At this time, the limiting post 80 just reaches the right-angle position of the limiting groove 501. By pulling the handle 5, the limiting post 80 slides into the inner position of the limiting groove 501. At this time, the locking screw 40 just locates at the inner position of the oblong groove 500. When the teleconverter 3 is not needed, the handle 5 is pressed inward and then rotated in the reverse direction to flip the teleconverter 3 to avoid the red dot sight 2. Through the synergistic effect, not only can the accuracy of flipping adjustment be improved, but also the rotational freedom of the rotating shaft 4 can be restricted to prevent the teleconverter 3 from flipping during operation.
[0049] Embodiment 2: A mechanism for quickly flipping a teleconverter, including a red dot sight 2 and a teleconverter 3. The mechanism for quickly flipping a teleconverter further includes:
[0050] A support base 1, the bottom of which can be installed on a guide rail. The top of the support base 1 is used for providing support. Specifically, the support base 1 can be fixed to a Picatinny rail or other rails. The specific installation structure will be mentioned later.
[0051] Among them, the red dot sight 2 is fixedly arranged at the rear side of the top of the support base 1 close to the human body. The red dot sight 2 provides a red dot aiming area. This part is an existing red dot sight 2 and will not be elaborated in this embodiment. In particular, when the object to be aimed at is relatively far away, there may be phenomena such as inaccurate aiming or unclear observation.
[0052] In particular, this embodiment includes a flipping mechanism. The flipping mechanism is rotatably adjustable on the support base 1. The flipping mechanism is arranged through the support base 1 along the length direction. The flipping mechanism is rotatably connected to the support base 1. The flipping mechanism is a manually adjustable mechanical structure.
[0053] This embodiment further includes a teleconverter 3. Among them, the bottom of the teleconverter 3 is fixed to the flipping mechanism. Therefore, the flipping mechanism is rotatably adjustable relative to the support base 1 and is fixed relative to the teleconverter 3. So when the flipping mechanism is manually rotated and adjusted, the teleconverter 3 can be flipped and controlled.
[0054] According to the above, in this embodiment, the doubling lens 3 can be adjusted to two states by the flipping mechanism. One state is that the doubling lens 3 is flipped and placed on the bracket base 1 and is on the same optical axis as the red dot sight 2. In this state, the doubling lens 3 participates in the magnification, so that it is convenient to aim at distant objects and can also increase the clarity of observation.
[0055] The other state is that the doubling lens 3 is flipped to avoid the red dot sight 2 and is located on the side of the bracket base 1. In this state, the doubling lens 3 does not participate in the work and does not affect the work of the red dot sight 2. Further, the flipping mechanism forces the doubling lens 3 to flip and move within the movable included angle range. This angle range is the most reasonable and is also the quickest to control. Define the position when the doubling lens 3 participates in the work as 0°. Flipping makes the doubling lens 3 just avoid the red dot sight 2, and it can be flipped to the in-place state at 0° and 90° in one step. The flipping mechanism realizes the effect of quickly flipping the doubling lens 3 with one hand and does not affect the original aiming position.
[0056] In this embodiment, a limiting mechanism is further included. The limiting mechanism is arranged between the bracket base 1 and the flipping mechanism and is used to limit the flipping mechanism to flip within the range of 0-90°. The limiting mechanism can accurately limit the manual control in-place condition of the flipping mechanism. With the cooperation of the limiting mechanism, when the doubling lens 3 needs to participate in the work, manually control the flipping mechanism to rotate 90°, and then it will be automatically pushed to the position of another state by the limiting mechanism, realizing accurate flipping in place; when the doubling lens 3 does not participate in the work, first press one end of the flipping mechanism in place and then rotate it 90° in the reverse direction to make the doubling lens 3 flip to avoid the red dot sight 2 automatically.
[0057] In this embodiment, specifically, the flipping mechanism is arranged on the left side of the bracket base 1 below the red dot sight 2. When the doubling lens 3 flips to avoid the red dot sight 2, the doubling lens 3 is on the same side as the flipping mechanism. When in use, the red dot sight 2 is close to the human body side. Defined from the human body side, the left side of the human body is the left side in this embodiment. Therefore, when it is found during the aiming process that the doubling lens 3 needs to participate, there is no need to change the aiming posture and position. Only the flipping mechanism can be controlled by the left hand, which is compared with the cumbersome process of the traditional additional installation of the doubling lens 3.
[0058] In this embodiment, further, a support base 10 is formed on the top of the bracket base 1. The inside of the support base 10 is hollowed out. The bottom of the red dot sight 2 is fixed on the support base 10. The flipping mechanism rotates through the support base 10. The design of hollowing out the bottom of the support base 10 can not only achieve light weight but also improve the heat dissipation effect of the red dot sight 2.
[0059] In this embodiment, further, the flipping mechanism includes a rotating shaft 4, a handle 5 and a torsion spring 6. The bottom of the auxiliary lens 3 is locked to the rotating shaft 4 through a fixing plate. There is a space between the auxiliary lens 3 and the red dot sight 2. The rotating shaft 4 rotates through the support base 10 and its two ends extend out from the front and back sides of the bracket base 1 respectively. The handle 5 is sleeved on one end of the rotating shaft 4 close to the red dot sight 2. The torsion spring 6 is sleeved on the rotating shaft 4 and is located between the support bases 10. The middle part of the torsion spring 6 is pressed and fixed to the rotating shaft 4 through a screw 7. When the rotating shaft 4 rotates, it forces the torsion spring 6 to generate a tension elastic force centered on the rotating shaft 4. When the auxiliary lens 3 is not working, the torsion spring 6 is in a relaxed state and there is no elastic potential energy. When the handle 5 rotates the rotating shaft 4, the torsion spring 6 generates a tension elastic force and generates elastic potential energy. When the state adjustment without the participation of the auxiliary lens 3 is required, first push the handle 5 in place, and then under the elastic force of the torsion spring 6, the rotating shaft 4 is automatically driven to flip back to its original position, which not only has a certain damping effect but also is convenient for quick return to the original position.
[0060] In this embodiment, further, the handle 5 includes a cylindrical part 50 and a handle part 51. The cylindrical part 50 is hollow in the middle. The cylindrical part 50 is sleeved on one end of the rotating shaft 4. An oblong slot 500 is formed in the cylindrical part 50. A locking screw 40 is fixed on the rotating shaft 4. When the cylindrical part 50 is sleeved on one end of the rotating shaft 4, the locking screw 40 passes through the oblong slot 500 for limit cooperation, so that the handle 5 can have a certain movement stroke in the axial direction of the rotating shaft 4. The cooperation between the handle 5 and the rotating shaft 4 through the locking screw 40 and the oblong slot 500 is coordinated. During the adjustment process, there is a certain movement stroke in the axial direction of the handle 5 relative to the rotating shaft 4, that is, the cooperation stroke between the locking screw 40 and the oblong slot 500. Through this cooperation, it can also prevent the handle 5 from falling off the rotating shaft 4.
[0061] In this embodiment, further, the limiting mechanism includes a limiting rod 8, one end of which is locked and fixed to the side of the bracket seat 1, and the other end of the limiting rod 8 is provided with a limiting column 80 located below the rotating shaft 4. The outer side of the cylinder 50 is provided with a limiting groove 501 extending at a right angle. When the cylinder 50 is sleeved on one end of the rotating shaft 4, the limiting column 80 is positioned and matched with the limiting groove 501. The cooperation between the locking screw 40 and the oblong groove 500 and the limiting column 80 and the limiting groove 501 forces the handle 5 to move a certain stroke in the axial direction of the rotating shaft 4 and drive the rotating shaft 4 to rotate within the range of the movable angle. The limiting mechanism and the flip The mechanisms work together. When the magnifier 3 is needed, the left hand rotates the handle 5. At this time, the limit column 80 just goes to the right angle position of the limit groove 501. By pulling the handle 5, the limit column 80 slides into the internal position of the limit groove 501. At this time, the locking screw 40 is just positioned at the internal position of the oblong groove 500; when the magnifier 3 is not needed, the handle 5 is pressed inward and then rotated in the opposite direction to flip the magnifier 3 to avoid the red dot sight 2. Through the synergistic effect, not only the accuracy of the flip adjustment can be improved, but also the rotational freedom of the rotating shaft 4 can be limited to prevent the magnifier 3 from flipping during operation.
[0062] In this embodiment, a rebound mechanism is also included, which includes a bolt 9 and a compression spring 11. The compression spring 11 passes through the center of the barrel 50 and is locked to one end of the rotating shaft 4. Both ends of the compression spring 11 are elastically abutted between the end of the rotating shaft 4 and the inside of the barrel 50. When the magnifier 3 avoids the red dot sight 2, the compression spring 11 is compressed. When the flip handle 5 is rotated, the elastic force of the compression spring 11 is released to push the handle 5 to move axially for a certain stroke until it is restricted by the limiting mechanism. When the handle 5 is pressed in, the compression spring 11 is gradually contracted, and the handle 5 is rotated in the opposite direction to flip the magnifier 3. The use of the rebound mechanism can produce a synergistic effect with the flip adjustment process and the limiting mechanism, eliminating the process of manually pulling the handle 5 and realizing automatic control.
[0063] The elastic force of the compression spring 11 forms a non-linear damping characteristic during the compression and release processes. When the magnifier is quickly flipped, the elastic deformation of the compression spring 11 can absorb the instantaneous impact force of the handle 5, avoiding mechanical impact noise or component wear caused by rapid operation, while enhancing the softness and controllability of the operation, achieving the buffering effect of dynamic damping; in the scenario of high-frequency vibration (such as continuous shooting), the resilience of the compression spring 11 and the pre-tightening force of the clearance elimination mechanism work together to form a vibration isolation layer; the elasticity of the compression spring 11 can offset part of the high-frequency vibration energy, preventing the vibration from being transmitted to the user's hand through the handle, not only enhancing the operation comfort but also reducing the aiming error, achieving the effects of vibration isolation and anti-interference; after long-term use, a small gap may be generated between the rotating shaft 4 and the support base 1 due to wear. The continuous elastic force of the compression spring 11 can adaptively push the handle 5 to move axially, dynamically filling the gap generated by wear and maintaining the precise positioning function of the limit mechanism; when the limit mechanism fails accidentally due to external force, the elastic force of the compression spring 11 can push the handle 5 to automatically rebound to the initial position, forcing the magnifier to return to the default state (avoiding the red dot sight), preventing aiming deviation or mechanical damage caused by mechanism out-of-control, and achieving the effect of redundant safety locking.
[0064] Embodiment 3: This embodiment further includes a clearance elimination mechanism on the basis of Embodiment 2. The clearance elimination mechanism includes an end cap 12, a saddle washer 13 and a flat washer 14. The flat washer 14 is sleeved on the other end of the rotating shaft 4 and embedded in one side of the support base 1. The end cap 12 is locked and fixed on one end of the rotating shaft 4. The saddle washer 13 is sleeved on the rotating shaft 4 and located outside the flat washer 14. The saddle washer 13 abuts between the flat washer 14 and the inside of the end cap 12. Through the cooperation of the saddle washer 13 and the flat washer 14, the axial mating clearance of the rotating shaft 4 can be eliminated, so that during the flipping adjustment process, there is only a single rotational degree of freedom, and there will be no axial movement error due to the mating clearance, not only making the adjustment process more accurate but also making the flipping process natural and smooth.
[0065] The cooperation of the clearance elimination mechanism and the spring-back mechanism forms a state of "preload" by the clearance elimination mechanism, so that the resilience of the compression spring 11 is no longer absorbed by the axial clearance, enabling the rotating shaft 4 to only retain the rotational degree of freedom required by the design and eliminating the cumulative error of the axial clearance generated by vibration during shooting.
[0066] Embodiment 4: This embodiment further includes an installation mechanism on the basis of Embodiment 3. The installation mechanism includes an adjusting rod 15, an adjusting nut 16, a pressing block 17, and an elastic element 18. The pressing block 17 is movably arranged inside one side of the bottom of the bracket seat 1. The adjusting rod 15 rotatably passes through the pressing block 17 and the other side of the bracket seat 1. The pressing block 17 is threadedly connected to the adjusting rod 15. The adjusting nut 16 is fixed to the end of the adjusting rod 15. The elastic element 18 is sleeved on the adjusting rod 15 and abuts between the pressing block 17 and the adjusting nut 16. When assembly is required, the bottom of the bracket seat 1 is faced towards the guide rail, and the adjusting nut 16 is twisted to drive the pressing block 17 to move and press tightly against the guide rail for installation and fixation. The elastic element 18 protects the surface of the pressing block 17 to avoid damage.
