Description

Technical Field

[0001] The present invention relates to the technical field of intercoms, and in particular to an intelligent intercom for special vehicles. Background Art

[0002] Because walkie-talkies rely primarily on radio signals for communication, they can be used as long as the frequency is set to the same, without incurring any call charges. They are extremely convenient and economical, making them widely used in various fields. With the advancement of technology, wireless smart walkie-talkies with visual functions have emerged. Smart walkie-talkies have larger screens and a smartphone-like appearance, enabling better video calls. They are actively used in special vehicles such as road sweepers, cementing trucks, fracturing trucks, highway tow trucks, concrete pump trucks, snowplows, ambulances, and fire trucks.

[0003] For example, the utility model patent with application number 201621425100.X and the name of "A new type of intelligent video intercom" discloses that a display screen is installed on the machine body, an intercom control button is installed below the display screen, a microphone and a wireless receiving device are installed below the intercom control button, and a camera is installed on the upper part of the machine body. Through the cooperation of the camera and the display screen, visual intercom can be well realized; another example is the appearance design of application number 202130306126.2 and the name of "Intelligent Public Network Intercom (Ultra-large Screen)". The large screen design enables the product to be used for calls, online videos, intercoms and other functions.

[0004] For the above-mentioned smart intercom, due to its larger screen, the visualization is clearer and more convenient. However, in special vehicles, such as sweepers, cementing trucks, fracturing trucks, and road tow trucks, a lot of dust is generated in the working environment during operation. Especially for sweepers, the dust raised during operation will enter the vehicle through various gaps in the vehicle. And it is precisely because of the existence of the large screen of the smart intercom that when the smart intercom is fixed on the fixed base for a long time (as is known to all, when the intercom is not in use, in order to prevent the intercom from being damaged due to shaking and collision, it is necessary to fix the intercom on the fixed base, and fix it. The base is fixed in the cab, and the intercom can be removed from the base for use after being unfixed when in use). Dust entering the car will directly adhere to the screen of the smart intercom, thereby affecting the video clarity of the intercom. Based on this, in the prior art, if the operator removes the smart intercom from the base and finds that there is a lot of dust adhering to the screen during a video conversation, it is necessary to use a rag, paper towel or other cleaning device to wipe and clean the screen separately during the video conversation. The wiping and cleaning action during the video conversation will inevitably affect the fluency of the normal video conversation. Summary of the Invention

[0005] The purpose of the present invention is to provide a special vehicle intelligent intercom to solve the above-mentioned shortcomings in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a special vehicle intelligent intercom, comprising a fixing seat for fixing the intercom, the fixing seat comprising a baffle abutting the top of the intercom and an elastic force-applying member for applying upward pressure to the intercom, the baffle being elastically slidably arranged on the fixing seat by a spring, the outer surface of the baffle being wrapped with a cleaning pad, the baffle being slid away from the top of the intercom so that the cleaning pad elastically abuts against the screen on the intercom during the process of releasing the intercom from fixation, and the elastic force-applying member pushing the intercom to slide upward so that the cleaning pad wipes the screen.

[0007] The above-mentioned special vehicle intelligent intercom, the fixed seat also includes a fixed support plate, and the fixed support plate is fixed with an upper limit card plate located above the baffle. The intercom is slidably plugged into the upper limit card plate, and the intercom is inserted into the upper limit card plate during the upward sliding process to prevent the intercom from falling from the fixed seat.

[0008] The above-mentioned special vehicle intelligent intercom, the upper limit card plate includes a limiting area for the intercom to slide through, and an opening is provided on one side of the limiting area to form two raised blocks on the upper limit card plate that correspond to the two borders in the width direction of the intercom. The inner walls of the two raised blocks slide in contact with the two borders in the width direction of the intercom without contacting the screen on the intercom.

[0009] The above-mentioned special vehicle intelligent intercom is provided with a guide plate for the intercom to pass through on the fixed support plate, and a guide groove is provided on the guide plate. The baffle is elastically slidably inserted in the guide groove by a spring. In the initial state, the end of the baffle close to the intercom extends to the outside of the guide groove, and the top surface of the baffle extending to the outside of the guide groove is an inclined surface that abuts and cooperates with the bottom of the intercom.

[0010] The above-mentioned special vehicle intelligent intercom is inserted into the guide plate from top to bottom and squeezes the inclined surface of the baffle to drive the baffle to slide elastically into the guide groove so that the cleaning pad elastically abuts the screen on the intercom until the top of the intercom is located below the baffle, so that the cleaning pad wipes the screen for the second time.

[0011] In the above-mentioned special vehicle intelligent intercom, the elastic force-applying member includes a movable plate elastically slidably arranged on a fixed support plate, and the movable plate is transmission-connected to the intercom. When the intercom slides downward, the movable plate is driven to slide and accumulate force to apply upward pressure to the intercom.

[0012] The above-mentioned special vehicle intelligent intercom has a first row of teeth fixed on the side of the intercom facing away from the screen, a second row of teeth fixed on the movable plate, and a gear rotatably arranged on the fixed support plate, which is located between the first row of teeth and the second row of teeth and meshes with both the first row of teeth and the second row of teeth.

[0013] In the above-mentioned special vehicle intelligent intercom, the movable plate is fixedly connected to the guide plate.

[0014] The above-mentioned special vehicle intelligent intercom has a telescopic rod fixedly installed on the movable plate, and the other end of the telescopic rod is fixedly provided with a pushing plate that fits with the end surface of the guide groove. A compression spring with an elastic force greater than that of the spring is connected between the pushing plate and the movable plate, and an elastic rope with an elastic force greater than that of the compression spring is connected between the pushing plate and the fixed support plate.

[0015] The above-mentioned special vehicle intelligent intercom drives the elastic rope to pull the push plate to slide away from the guide plate during the process of the intercom driving the movable plate to slide, so that the intercom passes between the push plate and the guide plate.

[0016] In the above technical solution, the present invention provides a special vehicle intelligent intercom that secures the intercom through the combined action of an elastic force-applying member and a baffle to prevent damage to the intercom caused by collisions. Due to the elastic sliding arrangement of the baffle, the intercom can be released when the sliding baffle is offset from the top of the intercom, thereby pushing the intercom upward under the action of the elastic force-applying member. Under the action of the spring, the cleaning pad on the baffle elastically abuts against the screen on the intercom, thereby causing relative sliding between the intercom and the cleaning pad during the upward sliding process, allowing the cleaning pad to wipe and clean the screen. Finally, the wiped intercom can be directly removed from the fixing base, eliminating the need to wipe the screen separately after removal. Compared with the prior art, the present invention can achieve screen cleaning during the intercom release process. Therefore, after removing the intercom from the fixing base, there is no need to interrupt the video conversation to perform a separate wiping and cleaning operation, thus not affecting the smoothness of the normal video conversation, and effectively solving the shortcomings of the prior art.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-8As shown, an embodiment of the present invention provides a special vehicle intelligent intercom, including a fixing base for fixing the intercom 2, the fixing base including a baffle 7 abutting the top of the intercom 2 and an elastic force member for applying upward pressure to the intercom 2, the baffle 7 is elastically slidably set on the fixing base by a spring 6, the outer surface of the baffle 7 is wrapped with a cleaning pad 701, the sliding baffle 7 is staggered with the top of the intercom 2 so that the cleaning pad 701 elastically abuts against the screen on the intercom 2 during the process of releasing the intercom 2, and the elastic force member pushes the intercom 2 to slide upward so that the cleaning pad 701 wipes the screen.

[0030] The special vehicle intelligent intercom provided in this embodiment is intended for use with special vehicles that generate dust in work environments, such as road sweepers, cementing trucks, fracturing trucks, and highway tow trucks, enabling workers to conduct visual video conversations with a better experience. The terms "up," "down," "left," and "right," etc., related to directions and positions, used in this embodiment, are relative to the accompanying drawings. The intercom in this embodiment is an intelligent intercom with visualization capabilities, and its appearance is similar to that of a smartphone. It lacks an upwardly protruding antenna, and the antenna is located inside the intercom. Specifically, the screen of intercom 2 is located in the middle of the right side of intercom 2, so that intercom 2 has two frames in the length direction and two frames in the width direction. The screen and the frames of intercom 2 are located in the same plane. Among them, the fixing seat is fixedly installed in the vehicle cab, and the intercom 2 is fixed on the fixing seat so that the intercom 2 will not collide due to the shaking of the vehicle, thereby protecting the safety of the intercom 2. Among them, the elastic force-applying member and the baffle 7 are components of the fixing seat, the elastic force-applying member is used to apply an upward force to the intercom 2, and the baffle 7 is used to limit the top of the intercom 2. Under the joint action of the elastic force-applying member and the baffle 7, the intercom 2 is fixed on the fixing seat. The baffle 7 is an elastic sliding setting. When the baffle 7 is offset from the top of the intercom 2 by an external force such as a finger sliding, the baffle 7 is not blocked. The intercom 2 is released from fixation, and the elastic force member generates an upward force on the intercom 2 to make the intercom 2 slide upward. At the same time, after the force on the baffle 7 is removed, the elastic force of the spring 6 generates a force on the baffle 7 toward the intercom 2 to elastically squeeze the baffle 7 to elastically squeeze the intercom 2. The screen on the intercom 2 abuts against the cleaning pad 701 wrapped on the baffle 7, so that in the process of the intercom 2 sliding upward, relative friction is generated between the cleaning pad 701 and the screen of the intercom 2, so that the screen of the intercom 2 is wiped and cleaned by the cleaning pad 701. Among them, the cleaning pad 701 is made of a soft material that will not scratch the screen. The cleaning pad 701 is detachably wrapped around the outer surface of the baffle 7. The open end of the cleaning pad 701 is connected or clamped by bonding, screws, or clamping. The friction between the inner surface of the cleaning pad 701 and the outer surface of the baffle 7 is greater than the friction between the cleaning pad 701 and the screen, so that the cleaning pad 701 is fixed when sliding friction occurs between the cleaning pad 701 and the screen, thereby making the cleaning pad 701 and the screen have a better wiping effect.The working principle of the special vehicle intelligent intercom provided by the present invention is as follows: first, the intercom 2 is fixed on the fixing seat. When the intercom 2 needs to be used, the intercom 2 is first unfixed, and finally the intercom 2 is removed from the fixing seat. When unfixing, a force is applied to the baffle 7 to make the baffle 7 slide until the baffle 7 is offset from the top of the intercom 2. The force applied to the baffle 7 is immediately removed. At this time, under the force applied by the elastic force applying member, the intercom 2 generates an upward force and slides upward. At the same time, under the elastic force of the spring 6, the end of the baffle 7 is pushed to squeeze the screen so that an elastic squeezing force is generated between the cleaning pad 701 and the screen. Under the action of the elastic squeezing force, the screen is wiped and cleaned by the cleaning pad 701, removing dust from the screen. When the intercom 2 rises to its limit position, the cleaning pad 701 is offset from the intercom 2 so that the screen is completely wiped by the cleaning pad 701. At this point, the intercom 2 is released and the intercom 2 is removed from the mounting base to conduct a video conversation. There is no need to wipe the screen separately after removing the intercom 2, which saves time for video conversations and avoids affecting the efficiency of normal video conversations. If the cleaning pad 701 squeezes a lot of dust, the cleaning pad 701 can be removed and cleaned at a leisure time and then rewrapped on the baffle 7. In the prior art, if the operator removes the smart intercom from the mounting base and finds a lot of dust adhering to the screen during a video conversation, they need to use a cleaning device such as a rag or paper towel to wipe the screen separately during the video conversation, which will inevitably affect the smoothness of the normal video conversation. The main innovation of the present invention is that the intercom 2 can be automatically cleaned during the process of unfixing the intercom 2 (that is, during the process of removing the intercom 2), and there is no need to perform separate cleaning after removing the intercom 2. This will not increase the burden on the staff, nor will it take up the time of the video conversation, thereby avoiding affecting the efficiency of the normal video conversation.

[0031] In this embodiment, the intercom 2 is fixed by the combined action of the elastic force-applying member and the baffle 7 on the intercom 2 to prevent the intercom 2 from being damaged by collision. Due to the elastic sliding arrangement of the baffle 7, when the sliding baffle 7 is offset from the top of the intercom 2, the intercom 2 can be released from the fixation, thereby pushing the intercom 2 to slide upward under the action of the elastic force-applying member, and the cleaning pad 701 on the baffle 7 can be elastically abutted against the screen on the intercom 2 under the action of the spring 6, so that the intercom 2 slides relative to the cleaning pad 701 during the upward sliding process, so that the cleaning pad 701 can wipe the screen. Finally, the wiped intercom 2 can be directly removed from the fixing seat without having to wipe the screen of the intercom 2 separately after removal. Compared with the prior art, the present invention can wipe and clean the screen during the process of unfixing the intercom 2, and then after the intercom 2 is removed from the fixing base, there is no need to occupy the time of the video conversation to perform a separate wiping and cleaning action on the screen, which will not affect the fluency of the normal video conversation and can effectively solve the shortcomings of the prior art.

[0032] In this embodiment, the fixed seat also includes a fixed support plate 1, on which is fixed an upper limit card plate 104 located above the baffle 7. The intercom 2 is slidably plugged into the upper limit card plate 104. The upper limit card plate 104 is used to limit the intercom 2. During the process of sliding upward, the intercom 2 is inserted into the upper limit card plate 104 to prevent the intercom 2 from falling from the fixed seat.

[0033] Furthermore, the upper limit card plate 104 includes a limiting area 1042 for the intercom 2 to slide through. An opening is provided on one side of the limiting area 1042 so that two raised blocks 1041 corresponding to the two borders in the width direction of the intercom 2 are formed on the upper limit card plate 104. The vertical distance between the two raised blocks 1041 is less than the width of the intercom 2. The inner walls of the two raised blocks 1041 slide in contact with the two borders in the width direction of the intercom 2 and do not contact the screen on the intercom 2, thereby preventing the screen from being scratched or squeezed by the upper limit card plate 104. The frame of the intercom 2 is made of metal and will not be scratched or squeezed by the upper limit card plate 104.

[0034] The guide plate 5 is provided with a guide groove 501, and the baffle 7 is elastically slidably inserted in the guide groove 501 by the spring 6. In the initial state, the end of the baffle 7 close to the intercom 2 extends to the outside of the guide groove 501, and the top surface of the baffle 7 extending to the outside of the guide groove 501 is an inclined surface that abuts and cooperates with the bottom of the intercom 2. The inclined surface is inclined downwardly toward the direction of the intercom 2. When the intercom 2 needs to be fixed and inserted downward into the guide plate 5, the bottom of the intercom 2 abuts and presses the inclined surface downward to make the baffle 7 slide toward the inside of the guide groove 501, so that the spring 6 is compressed and generates an elastic force until the bottom of the intercom 2 is offset from the baffle 7. At this time, under the elastic force of the spring 6, the baffle 7 presses the intercom 2 toward the direction of the intercom 2, and the screen of the intercom 2 faces the baffle 7, so that the cleaning pad 701 elastically presses the screen.

[0035] It can be seen that the intercom 2 is inserted into the guide plate 5 from top to bottom and squeezes the inclined surface of the baffle 7 to drive the baffle 7 to slide elastically into the guide groove 501 so that the cleaning pad 701 elastically abuts the screen on the intercom 2 until the top of the intercom 2 is located below the baffle 7, so that the cleaning pad 701 wipes the screen a second time. Based on this, when the intercom 2 is fixed after use, the cleaning pad 701 can wipe the screen a second time. The bottom surface of the baffle 7 is flat. When the top of the intercom 2 is located below the baffle 7, the spring 6 pushes the baffle 7 to slide to the top of the intercom 2, so that the top of the intercom 2 is limited by the baffle 7.

[0036] In this embodiment, the elastic force-applying member includes a movable plate 4 elastically slidingly arranged on the fixed support plate 1. The movable plate 4 is transmission-connected to the intercom 2. When the intercom 2 slides downward, the movable plate 4 is driven to slide and accumulate force to apply upward pressure to the intercom 2. The baffle 7 cooperates with the blocking and limiting effect of the intercom 2, so that the intercom 2 is fixed on the fixed seat.

[0037] Furthermore, a first row of teeth 201 is fixedly provided on the side of the intercom 2 facing away from the screen, a second row of teeth 401 is fixedly provided on the movable plate 4, and a gear 3 is rotatably provided on the fixed support plate 1 and is located between the first row of teeth 201 and the second row of teeth 401 and meshes with both the first row of teeth 201 and the second row of teeth 401. When fixing the intercom 2, first slide the intercom 2 downward through the upper limit card plate 104 until the first row of teeth 201 abuts and meshes with the gear 3. During this process, the upper limit card plate 104 guides the intercom 2 so that the first row of teeth 201 can accurately abut and mesh with the gear 3. Then continue to slide the intercom 2 downward so that the first row of teeth 201 drives the gear 3 to rotate. The rotation of the gear 3 drives the movable plate 4 to slide upward through the second row of teeth 401, thereby causing the movable plate 4 to gradually elastically store force. When the intercom 2 slides down to the fixed position, the elastic storage force of the movable plate 4 reaches the maximum. At this time, the elastic storage force of the movable plate 4 has a downward pulling force on the movable plate 4 so that the gear 3 generates an upward thrust on the intercom 2. Therefore, under the blocking effect of the baffle 7 on the top of the intercom 2, the intercom 2 can be fixed.

[0038] Further (please refer to the attached Figure 4 ), a lower limit card plate 105 located below the guide plate 5 is fixed on the fixed support plate 1. The structure of the lower limit card plate 105 is the same as that of the upper limit card plate 104. The intercom 2 is inserted into the lower limit card plate 105 during the downward sliding process. At the same time, when the baffle 7 is located at the top of the intercom 2, the frame of the intercom 2 abuts and fits with the end surface of the guide groove 501. Therefore, under the joint action of the lower limit card plate 105 and the end surface of the guide groove 501, the intercom 2 is further limited, so that the intercom 2 is firmly fixed.

[0039] It can be seen from the above structural design that the intercom 2 is in a suspended state when it is fixed, so that the bottom of the intercom 2, the screen of the intercom 2, and the back of the intercom 2 (the side away from the screen) will not be blocked by objects, which is more conducive to the heat dissipation of the intercom 2.

[0040] In this embodiment, the movable plate 4 is fixedly connected to the guide plate 5. When the movable plate 4 slides upward, it can drive the guide plate 5 to move upward synchronously. The upward movement of the guide plate 5 drives the baffle 7 to move upward, and the intercom 2 slides downward. Therefore, when the intercom 2 is fixed, the downward sliding distance of the intercom 2 can be greatly reduced, thereby reducing the volume of the fixing base, making its structure more compact, and reducing space occupancy.

[0041] At the same time, two side baffles 502 are fixedly installed on the top of the guide plate 5, and the two side baffles 502 correspond to the two borders in the width direction of the intercom 2 one by one. When the intercom 2 passes through the upper limit card plate 104 to make the first row of teeth 201 abut against the gear 3, the inner walls of the two side baffles 502 slide and fit with the two borders in the width direction of the intercom 2. Since the gear 3 is engaged with the second row of teeth 401 on the movable plate 4, and the movable plate 4 has elastic resistance, the elastic resistance of the movable plate 4 is greater than the gravity of the intercom 2, and the intercom 2 can be limited by the joint action of the gear 3, the upper limit card plate 104 and the side baffles 502, so that the intercom 2 will not be moved from the fixed The intercom 2 is detached from the seat, so when the intercom 2 is used, the intercom 2 can be inserted between the gear 3 and the two side baffles 502 through the upper limit card plate 104 for use, so as to free the staff's hands. At this time, the fixing seat plays the role of a bracket, which is the same as the supporting effect of a mobile phone holder on a mobile phone; when the intercom 2 needs to be fixed, a downward force can be directly applied to the intercom 2, which is very convenient to operate; furthermore, when the intercom 2 is released, the gear 3 is engaged with the first row of teeth 201, so that the intercom 2 will not be ejected immediately, but will be limited between the gear 3 and the two side baffles 502 and pass through the upper limit card plate 104, which can ensure the safety of the intercom 2.

[0042] Furthermore, during the downward sliding of the intercom 2, when the top of the intercom 2 is located below the baffle 7, the top of the side baffle 502 abuts against the bottom of the upper limit clamp 104, so that the side baffle 502 cannot continue to move up, and the intercom 2 cannot continue to move down. Based on this, when fixing the intercom 2, it is only necessary to press the intercom 2 to the extreme position to fix the intercom 2, and the intercom 2 will not be separated from the fixing seat during the sliding of the intercom 2, so as to ensure that the intercom 2 is safely fixed.

[0043] In this embodiment, a cavity is provided inside the fixed support plate 1. An open opening 101 communicating with the cavity is provided on one side of the fixed support plate 1 near the guide plate 5. Two symmetrically arranged first slideways 102 and two symmetrically arranged second slideways 103 are provided on the inner wall of the fixed support plate 1. First sliding plates 402 are fixedly mounted on the front and rear sides of the movable plate 4. Second sliding plates 503 are fixedly mounted on the front and rear sides of the guide plate 5. The two first sliding plates 402 are slidably connected to the two first slideways 102 in a one-to-one correspondence, and the two second sliding plates 503 are slidably connected to the two second slideways 103 in a one-to-one correspondence. The gear 3 is rotatably set in the cavity of the fixed support plate 1 through a vertical plate 106 fixedly mounted in the cavity of the fixed support plate 1 and extends through the open opening 101 to the outside of the cavity of the fixed support plate 1 to engage with the first row of teeth 201. By providing a cavity inside the fixed support plate 1, the structural compactness of the fixed seat can be further improved, thereby further reducing the space occupied by the fixed seat.

[0044] In this embodiment, the number of the first row of teeth 201 , the second row of teeth 401 and the gear 3 are both two and symmetrically arranged, thereby improving the force uniformity of the intercom 2 and the movable plate 4 .

[0045] In this embodiment, a telescopic rod 9 is fixedly mounted on the movable plate 4. The other end of the telescopic rod 9 is fixedly mounted with a push plate 8 that mates with the end surface of the guide groove 501. A compression spring 10, whose elastic force is greater than that of the spring 6, is connected between the push plate 8 and the movable plate 4. An elastic cord 13, whose elastic force is greater than that of the compression spring 10, is connected between the push plate 8 and the fixed support plate 1. In the initial state (i.e., when the intercom 2 is not placed on the fixed base), the compression spring 10 pushes the push plate 8 to squeeze the baffle 7 and slide it toward the inside of the guide groove 501 until the baffle 7 is completely slid into the guide groove 501. This prevents external dust from coming into contact with the cleaning pad 701 on the baffle 7, thereby reducing contamination of the cleaning pad 701 by external dust.

[0046] Furthermore, because the elastic force of the elastic rope 13 is greater than the elastic force of the compression spring 10, the elastic rope 13 will be stretched and elastically deformed only when the compression spring 10 is compressed to the limit state. Therefore, when the intercom 2 is fixed, the intercom 2 drives the movable plate 4 to slide, driving the elastic rope 13 to pull the pushing plate 8 to slide in the direction away from the guide plate 5, so that the intercom 2 passes between the pushing plate 8 and the guide plate 5, that is, before the intercom 2 slides down to the position of the guide plate 5, the sliding distance of the pushing plate 8 is greater than the thickness of the intercom 2, so that the intercom 2 can pass between the pushing plate 8 and the guide plate 5. After the pushing plate 8 slides to the limit state, as the intercom 2 slides down, the movable plate 4 continues to move upward, thereby driving the elastic rope 13 to produce tensile deformation until the intercom 2 slides to the fixed position. At this time, under the joint action of the elastic rope 13 and the compression spring 10, pressure is applied to the intercom 2 to fix the intercom 2.

[0047] Among them, a first directional wheel 11 is rotatably provided on the movable plate 4, and a second directional wheel 12 is rotatably provided in the cavity of the fixed support plate 1. The end of the elastic rope 13 is fitted around the first directional wheel 11 and the second directional wheel 12 in sequence and then fixedly connected to the fixed support plate 1, so that the elastic rope 13 located between the first directional wheel 11 and the push plate 8 is in a horizontal state so that the pulling force of the elastic rope 13 on the push plate 8 is more concentrated.

[0048] In this embodiment, when the intercom 2 is fixed, an operating space 14 is formed between the end of the baffle 7 and the push plate 8. When the intercom 2 needs to be released, a finger is inserted into the operating space 14 to apply external force to the baffle 7 to make the baffle 7 slide.

[0049] There are multiple and identical numbers of telescopic rods 9 and compression springs 10 , and each compression spring 10 is set on each telescopic rod 9 one by one.

[0050] Furthermore, in the initial state, the bottom of the push plate 8 abuts against the top of the lower limit clamping plate 105, so that the movable plate 4 and the guide plate 5 are limited to specific positions.
