Description

Technical Field

[0001] The invention relates to the technical field of tooth morphology collection, and in particular to a tooth slope morphology measurement collector. Background Art

[0002] Due to the different degrees of uniformity of human teeth growth and the increasing wear of teeth with age, the problem of increased cusp inclination can easily occur. A larger inclination of teeth will directly lead to an increase in the horizontal component of force applied to the occlusal surface, which in turn becomes an important factor leading to tooth cracks. For this reason, it is necessary to correct the inclination of teeth of different people to avoid causing dental diseases such as tooth cracks.

[0003] The method of measuring the inclination of teeth is mostly to measure the occlusal plaster model. Before making the occlusal plaster model, the tooth shape needs to be collected. In the prior art, the method of collecting the tooth shape is to apply silicone rubber on a collection plate, and use the rapid plasticity of silicone rubber to put the collection plate coated with silicone rubber into the oral cavity so that the silicone rubber covers the entire row of teeth on the upper or lower jaw, and press the left and right sides of the bottom of the collection plate hard so that the silicone rubber tightly wraps the entire row of teeth. Finally, wait for about two minutes for the silicone rubber to solidify and take shape, then take the collection plate together with the silicone rubber out of the oral cavity, thereby realizing the collection of tooth shape.

[0004] In order to collect more accurate and complete tooth morphology, the operator needs to repeatedly press the left and right sides of the bottom of the collection plate with force during collection so that the silicone rubber can more completely wrap the entire row of teeth. When pressing the left and right sides of the bottom of the collection plate, it is difficult to ensure that the height changes of the left and right sides of the collection plate are always consistent during the continuous pressing process. In the prior art, since the collection plate is an integral design, a linkage will occur when pressing the left and right sides of the collection plate. During the pressing process, the change in the height of the left side of the collection plate will affect the height of the right side, and the change in the height of the right side will also affect the height of the left side. Since the timing and size of the force applied to the left and right sides of the collection plate are difficult to keep consistent, the left and right height difference of the collection plate will change repeatedly during the entire pressing process of the collection plate, causing the collection plate to tilt left and right at multiple different angles, causing the left and right sides of the collection plate to be prone to different degrees of horizontal displacement of the teeth, thereby easily causing a horizontal gap between the teeth and the silicone rubber, so that the silicone rubber cannot maintain a tight fit with the teeth, resulting in a large deviation in the collection of tooth morphology, which will directly affect the accuracy of tooth inclination measurement.

[0007] It also includes a first locking mechanism disposed between the left collecting plate and the right collecting plate. When the opposite surfaces of the left collecting plate and the right collecting plate are completely in contact with each other, the first locking mechanism locks the left collecting plate and the right collecting plate.

[0012] In the above-mentioned tooth inclination morphology measurement collector, the elastic limiting rod includes a vertical rod and a cross rod, the cross rod is slidably plugged with the vertical rod through a spring, and when the opposite surfaces of the lower concave plate and the upper concave plate are in contact, the top of the cross rod is in contact with the bottom of the upper concave plate.

[0013] In the tooth inclination morphology measurement collector mentioned above, the longitudinal section of the slot is trapezoidal, and the width of the top opening of the slot is greater than the width of the bottom opening.

[0014] The above-mentioned tooth inclination morphology measurement collector, the right collection plate also includes a third arc plate rotatably connected to the free end of the first arc plate, the left collection plate also includes a fourth arc plate rotatably connected to the free end of the second arc plate, the free end of the first arc plate and the third arc plate and the free end of the second arc plate and the fourth arc plate are all rotatably connected via a second locking mechanism.

[0015] The above-mentioned tooth inclination morphology measurement collector, the second locking mechanism includes an inner tooth ring fixedly mounted on the free end of the first arc-shaped plate and a matching piece, the matching piece includes a shaft body and a movable outer tooth ring slidably connected to the shaft body up and down, and the movable outer tooth ring is snap-fitted with the inner tooth ring.

[0041] 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.

[0042] like Figure 1-20 As shown, a tooth inclination morphology measurement collector provided by an embodiment of the present invention includes a left collecting plate 2 and a right collecting plate 1 for placing silicone rubber, and the left collecting plate 2 and the right collecting plate 1 can move independently in the height direction; and also includes a first locking mechanism arranged between the left collecting plate 2 and the right collecting plate 1, when the opposite surfaces of the left collecting plate 2 and the right collecting plate 1 are completely fitted, the locking mechanism locks the left collecting plate 2 and the right collecting plate 1.

[0043] The tooth inclination shape measurement collector provided in this embodiment is used to collect the shape of the entire row of teeth in the upper or lower jaw, and then measure the tooth inclination after plaster injection molding of the tooth shape. The words such as "upper", "lower", "left", and "right" in this embodiment are relative to the attached Figure 1 , 2Specifically, the top of the left collecting plate 2 and the right collecting plate 1 are used to apply silicone rubber, and when sampling teeth, it is achieved by pressing the bottom of the left collecting plate 2 and the right collecting plate 1. The left collecting plate 2 and the right collecting plate 1 can move separately in the height direction, so that when the left collecting plate 2 and the right collecting plate 1 are pressed, the two do not interfere with each other, and thus do not affect each other. The change in the height of the right collecting plate 1 will not affect the height of the left collecting plate 2, and vice versa. The first locking mechanism is used to lock the left collecting plate 2 and the right collecting plate 1, so that the left collecting plate 2 and the right collecting plate 1 are connected as a whole, so that after the collection is completed, when the left collecting plate 2 and the right collecting plate 1 are taken out of the cavity, the deformation of the collecting plate and the silicone rubber will not be caused. The thickness of the left collecting plate 2 and the right collecting plate 1 is the same. When locked, the left collecting plate 2 and the right collecting plate 1 are exactly the same in height. The working principle of the tooth inclination morphology measurement collector provided by the present invention is: first, a row of teeth located on the upper jaw are sampled, and first, when the left collection plate 2 and the right collection plate 1 are not locked (at this time, there is a height difference between the top of the left collection plate 2 and the top of the right collection plate 1), the silicone rubber is evenly applied to the top of the left collection plate 2 and the top of the right collection plate 1, and the thickness of the silicone rubber on the left collection plate 2 and the thickness of the silicone rubber on the right collection plate 1 are kept almost the same, so that the silicone rubber on the left collection plate 2 and the right collection plate 1 will not be too much on one side and too little on the other side, so that the silicone rubber on the left collection plate 2 and the right collection plate 1 can both better and completely cover the teeth.Because there is a height difference between the top of the left collecting plate 2 and the top of the right collecting plate 1, when applying silicone rubber, the silicone rubber located on the top of the left collecting plate 2 and the silicone rubber located on the top of the right collecting plate 1 also have a height difference, so that the silicone rubber on the left collecting plate 2 and the silicone rubber on the right collecting plate 1 will not be connected as a whole, thereby not affecting the independent movement of the left collecting plate 2 and the right collecting plate 1 in the height direction. Then, the left collecting plate 2 and the right collecting plate 1 coated with silicone rubber are sent into the cavity, and the left collecting plate 2 and the right collecting plate 1 are controlled by force to be close to a locked state in height (in this state, when force is applied to the collecting plate located above, the collecting plate located below will not be driven, and at this time, the collecting plate located above has the maximum space for independent upward movement). Now assume that the left collecting plate 2 is located below the right collecting plate 1, first make the silicone rubber on the right collecting plate 1 abut against the teeth on the right side (at this time, due to the height difference, the silicone rubber on the left collecting plate 2 does not abut against the teeth on the left side) , and apply pressure to the bottom of the right collection plate 1, so that the right collection plate 1 drives the silicone rubber to move upward until the silicone rubber wraps the right teeth. During this process, the left collection plate 2 will not be affected by the right collection plate 1. Then keep the right collection plate 1 still, and start to apply pressure to the bottom of the left collection plate 2, so that the left collection plate 2 drives the silicone rubber to move upward until the height of the left collection plate 2 moves up to the same height as the right collection plate 1 (during this process, the right collection plate 1 will not be affected by the left collection plate 2). At this time, under the action of the first locking mechanism, the right collection plate 1 and the left collection plate 2 are locked as a whole, and the positions of the right collection plate 1 and the left collection plate 2 are kept still. After waiting for about two minutes, the right collection plate 1 and the left collection plate 2 can be taken out of the cavity, because the right collection plate 1 and the left collection plate 2 are locked as a whole and will not move relative to each other, so that deformation will not occur. After that, the same principle can be used to sample a row of teeth on the lower jaw, which will not be repeated. During the entire sampling process, the force applied to the right collection plate 1 and the left collection plate 2 is done in one go without interfering with each other, and it is not easy for the silicone rubber and the teeth to repeatedly produce different degrees of displacement changes in the horizontal direction, which can better ensure the fit between the teeth and the silicone rubber. In the prior art, since the collection plate is an integral design, a linkage will occur when pressing the left and right sides of the collection plate. During the pressing process, the change in the height of the left side of the collection plate will affect the height of the right side, and the change in the height of the right side will also affect the height of the left side. Since the timing and size of the force applied to the left and right sides of the collection plate are difficult to keep consistent, the left and right height difference of the collection plate will change repeatedly during the entire pressing process of the collection plate, causing the collection plate to tilt left and right at different angles multiple times, causing the left and right sides of the collection plate to be prone to different degrees of horizontal displacement of the teeth, thereby easily causing a horizontal gap between the teeth and the silicone rubber, so that the silicone rubber cannot maintain a tight fit with the teeth, resulting in a large deviation in the collection of tooth morphology, which will directly affect the accuracy of tooth inclination measurement.The main innovation of the present invention is that the entire collection plate is divided into two parts, so that the linkage between the left and right sides of the collection plate is cut off, so that there is no mutual interference when the left and right sides of the collection plate are pressed, and the situation in which a gap is generated between the teeth and the silicone rubber due to the left-right linkage can be avoided, so as to ensure the accuracy of the subsequent tooth inclination measurement.

[0044] In the present embodiment, the left collecting plate 2 and the right collecting plate 1 are provided so that the collecting plates are divided, and when the opposite surfaces of the left collecting plate 2 and the right collecting plate 1 are completely fitted together, the left collecting plate 2 and the right collecting plate 1 are automatically locked by the first locking mechanism so that the left collecting plate 2 and the right collecting plate 1 are connected as a whole, and the left collecting plate 2 and the right collecting plate 1 can move up and down independently without interfering with each other, and the linkage between the left and right sides of the collecting plates is cut off. Therefore, even if the timing and magnitude of the force applied to the right collecting plate 1 and the left collecting plate 2 are different during the process of pressing the collecting plates, it is not easy to cause different degrees of horizontal displacement between the left and right sides of the collecting plates and the teeth, and the silicone rubber can be kept in fit with the entire row of teeth. Compared with the prior art, the present invention divides the complete collection plate into a left collection plate 2 and a right collection plate 1 which can interact with each other independently up and down without interfering with each other, so that the linkage between the left and right sides of the collection plate is cut off. While ensuring that the silicone rubber can wrap the entire row of teeth, the teeth and the silicone rubber can fit tightly together, and it is not easy to have gaps between the teeth and the silicone rubber, thereby ensuring the accuracy of the tooth inclination measurement, which can effectively solve the shortcomings of the prior art.

[0045] In this embodiment, the left collection plate 2 and the right collection plate 1 are made of a hard material that is not easily deformed, which further prevents the collection plate from being deformed when being taken out of the cavity and causing deformation of the tooth sampling shape.

[0046] In this embodiment, the right collecting plate 1 includes a first curved plate 101, and a lower concave plate 1011 is provided at the end of the first curved plate 101. The left collecting plate 2 includes a second curved plate 201, and an upper concave plate 2011 corresponding to the lower concave plate 1011 is provided at the end of the second curved plate 201. The lower concave plate 1011 is rotatably connected with the upper concave plate 2011 through a pin shaft 3. The pin shaft 3 includes a main body 301 and a cover body 302 fixedly installed at the bottom of the main body 301. The diameter of the cover body 302 is larger than the diameter of the main body 301, and is used to limit the upper concave plate 2011 to prevent the upper concave plate 2011 from detaching from the pin shaft 3. The first arc plate 101 and the second arc plate 201 are both bent inward, and the arc design of the right collecting plate 1 and the left collecting plate 2 can better match the arrangement of the teeth in the cavity, so that the silicone rubber on the right collecting plate 1 and the left collecting plate 2 can cover the entire row of teeth without occupying too much cavity space, so that the tongue will not be squeezed by the collecting plate, providing better comfort for the user. The concave surface of the lower concave plate 1011 is located on the bottom surface of the first arc plate 101, and the concave surface of the upper concave plate 2011 is located on the top surface of the second arc plate 201. When the opposite surfaces of the lower concave plate 1011 and the upper concave plate 2011 are fitted, the first locking mechanism locks the lower concave plate 1011 and the upper concave plate 2011, that is, the right collecting plate 1 and the left collecting plate 2 are locked.

[0047] By utilizing the rotatable connection between the lower concave plate 1011 and the upper concave plate 2011, the right collecting plate 1 and the left collecting plate 2 can rotate relative to each other, thereby changing the distance between the right collecting plate 1 and the left collecting plate 2. Based on this, the distance between the right collecting plate 1 and the left collecting plate 2 can be reasonably adjusted according to the different distances between the teeth on the left and right sides of the upper or lower jaw of different people, so that the right collecting plate 1 and the left collecting plate 2 can cover the tooth types of more people, greatly improving the applicability of the collector.

[0048] In this embodiment, the lower concave plate 1011 is located above the upper concave plate 2011, the lower concave plate 1011 is fixedly connected to the pin shaft 3, the upper concave plate 2011 is rotatably connected to the pin shaft 3, a circular hole 2015 matching the pin shaft 3 is opened on the upper concave plate 2011, and the top of the pin shaft 3 passes through the circular hole 2015 and is fixedly connected to the lower concave plate 1011.

[0049] Among them, the side surfaces opposite to the lower concave plate 1011 and the second curved plate 201 are both curved surfaces, the arc center of the curved surface is located on the axis line of the circular hole 2015, and the side surfaces opposite to the lower concave plate 1011 and the second curved plate 201 are slidingly fitted, so that when the first curved plate 101 and the second curved plate 201 rotate relative to each other, the side surfaces opposite to the lower concave plate 1011 and the second curved plate 201 will perform a fitting relative rotation. This design method will not only not affect the relative rotation of the first curved plate 101 and the second curved plate 201, but also there will be no gap between the top surface of the first curved plate 101 and the top surface of the second curved plate 201, so that when the right collecting plate 1 and the left collecting plate 2 are locked, the silicone rubber located on the top surface of the first curved plate 101 and the silicone rubber located on the top surface of the second curved plate 201 can be tightly connected, and it is not easy to cause the teeth to be not wrapped by the silicone rubber.

[0050] In this embodiment, the first locking mechanism includes a tooth groove 1013 opened on the bottom surface of the lower concave plate 1011 and coaxial with the pin shaft 3, and a fixed outer tooth ring 5 arranged on the top surface of the upper concave plate 2011 and coaxial with the pin shaft 3. The fixed outer tooth ring 5 is fixedly connected to the upper concave plate 2011, and the fixed outer tooth ring 5 is snap-fitted with the tooth groove 1013. The outer surface of the fixed outer gear ring 5 is provided with a plurality of circumferentially equidistantly arranged latching teeth, and the inner wall of the tooth groove 1013 is provided with a plurality of circumferentially equidistantly arranged latching grooves. When the distance between the lower concave plate 1011 and the upper concave plate 2011 is the largest, the fixed outer gear ring 5 and the tooth groove 1013 are not in contact, and at this time, the first arc plate 101 and the second arc plate 201 can rotate relative to each other; as the distance between the second arc plate 201 and the first arc plate 101 decreases, the fixed outer gear ring 5 is inserted into the tooth groove 1013, so that the first arc plate 101 and the second arc plate 201 cannot rotate, thereby realizing the rotation locking of the first arc plate 101 and the second arc plate 201;

[0051] Furthermore, the first locking mechanism also includes an elastic limiting rod 4 arranged on the lower concave plate 1011 and a slot 2013 opened on the upper concave plate 2011 corresponding to the elastic limiting rod 4. The slot 2013 is arc-shaped. The arc-shaped design ensures that when the first arc plate 101 and the second arc plate 201 rotate relative to each other, the elastic limiting rod 4 will not hinder the rotation. The arc center of the slot 2013 is located on the axis line of the pin shaft 3, so that the elastic limiting rod 4 can rotate smoothly along the slot 2013. The elastic limiting rod 4 is inserted into the slot 2013 and engages with the slot 2013. When the opposite surfaces of the lower concave plate 1011 and the upper concave plate 2011 are not in contact (i.e., the right collecting plate 1 and the left collecting plate 2 are not locked), the elastic limiting rod 4 is not engaged with the slot 2013; when the opposite surfaces of the lower concave plate 1011 and the upper concave plate 2011 are in contact, the elastic limiting rod 4 will automatically engage with the slot 2013, and at this time, the distance between the lower concave plate 1011 and the upper concave plate 2011 is locked at zero, thereby achieving the locking of the distance between the first arc plate 101 and the second arc plate 201.

[0052] In this embodiment, the elastic limiting rod 4 includes a vertical rod 401 and a horizontal rod 402. The top of the vertical rod 401 is fixedly connected to the bottom surface of the lower concave plate 1011. The horizontal rod 402 is slidably plugged with the vertical rod 401 through a spring (not shown in the figure). When the opposite surfaces of the lower concave plate 1011 and the upper concave plate 2011 are in contact, the top of the horizontal rod 402 is in contact with the bottom of the upper concave plate 2011. By utilizing the elasticity of the spring on the horizontal rod 402, when the opposite surfaces of the lower concave plate 1011 and the upper concave plate 2011 are not in contact, the horizontal rod 402 is located in the slot 2013, and the inner wall of the slot 2013 slides and squeezes the free end of the horizontal rod 402. The free end of the horizontal rod 402 is a semicircular body, which can reduce the friction between the horizontal rod 402 and the inner wall of the slot 2013. At this time, the friction between the horizontal rod 402 and the slot 2013 is not enough to affect the independent movement of the first curved plate 101 and the second curved plate 201 in height. As the distance between the lower concave plate 1011 and the upper concave plate 2011 continues to decrease, the cross bar 402 continues to move downward relative to the slot 2013 until the distance between the lower concave plate 1011 and the upper concave plate 2011 is zero, and the cross bar 402 just emerges from the slot 2013. Under the action of the spring, the cross bar 402 slides outward so that the top of the cross bar 402 fits with the bottom of the upper concave plate 2011, thereby achieving the distance locking between the lower concave plate 1011 and the upper concave plate 2011.

[0053] Furthermore, the longitudinal section of the slot 2013 is trapezoidal, and the width of the top opening of the slot 2013 is greater than the width of the bottom opening. The width of the upper half of the slot 2013 is greater than the sum of the maximum length that the crossbar 402 can extend and the diameter of the vertical rod 401, so that when the crossbar 402 is located in the upper half of the slot 2013, the crossbar 402 will not contact the inner wall of the slot 2013. With this design, firstly, the cross bar 402 can smoothly enter the slot 2013 from the top of the slot 2013, even if the cross bar 402 is separated from the slot 2013; secondly, in the first half section when the lower concave plate 1011 and the upper concave plate 2011 are close to each other, the cross bar 402 will not contact the inner wall of the slot 2013, and the friction between them is zero, so that the independent movement of the first curved plate 101 and the second curved plate 201 in height will not be affected at all; in the second half section when the lower concave plate 1011 and the upper concave plate 2011 are close to each other, although the cross bar 402 will contact the inner wall of the slot 2013, the cross bar 402 is The thrust of the spring is greatly reduced, so that the friction between the cross bar 402 and the inner wall of the slot 2013 is greatly reduced, and the influence of the separate movement of the first arc plate 101 and the second arc plate 201 in height is reduced to a minimum; thirdly, because of the trapezoidal design of the longitudinal section of the slot 2013, when the right collection plate 1 and the left collection plate 2 are close to each other, the friction between the cross bar 402 and the inner wall of the slot 2013 is in a gradually increasing state. By utilizing the gradually increasing friction, the operator can more easily control the height of the left collection plate 2 and the right collection plate 1 to be close to the locked state, so as to improve the accuracy of control.

[0054] In this embodiment, there are two elastic limiting rods 4 and two slots 2013 , and the two elastic limiting rods 4 are 180° apart to improve the locking stability of the first locking mechanism.

[0055] Furthermore, the right collecting plate 1 also includes a third curved plate 102 rotatably connected to the free end of the first curved plate 101, and the left collecting plate 2 also includes a fourth curved plate 202 rotatably connected to the free end of the second curved plate 201. The free end of the first curved plate 101 and the third curved plate 102, as well as the free end of the second curved plate 201 and the fourth curved plate 202 are both rotatably connected via a second locking mechanism. There are two second locking mechanisms, which are respectively located between the free end of the first curved plate 101 and the third curved plate 102, and between the free end of the second curved plate 201 and the fourth curved plate 202. The two second locking mechanisms are respectively used for rotation locking between the first curved plate 101 and the third curved plate 102, and rotation locking between the second curved plate 201 and the fourth curved plate 202.

[0056] By adding the third curved plate 102 and the fourth curved plate 202 which are rotatably arranged, the adaptability of the right collecting plate 1 and the left collecting plate 2 to the entire row of teeth of different people can be improved, and the applicable scope of the collector can be further improved;

[0057] Furthermore, the above structure can improve the scope of application of the collector while maintaining the consistency of the shape of the collection plate in the oral cavity and outside, and prevent the collection plate from being deformed after being taken out of the cavity, which may cause inaccurate tooth shape sampling. Specifically, in the prior art, in order to protect the safety of the oral cavity, the sampling plate is mostly made of soft materials. When the sampling plate is sent to the oral cavity, if the oral cavity is relatively small relative to the sampling plate, the free end of the soft sampling plate (the sampling plate has two free ends, and the distance between the two free ends is the largest) will be squeezed by the oral cavity and deformed. This deformation is difficult to be discovered by the operator (because the free end of the sampling plate is located on the inner side of the cavity). When the sampling is completed and the sampling plate is taken out of the oral cavity, the deformed sampling plate will automatically return to its original state, thereby causing the silicone rubber to deform and causing changes in the sampling of tooth shape. Compared with the prior art, the present invention provides a rotatable third arc plate 102 and a fourth arc plate 202, so that when the sampling plate is sent into the oral cavity, if the oral cavity is small, the inner wall of the oral cavity will squeeze the free end of the third arc plate 102 and the free end of the fourth arc plate 202 respectively, so that the third arc plate 102 and the fourth arc plate 202 are respectively rotated in the direction of approaching each other, so that the right collecting plate 1 and the left collecting plate 2 are adapted to the size of the oral cavity, and then the third arc plate 102 and the fourth arc plate 202 are respectively locked and no longer rotated by the second locking mechanism. At the same time, under the action of the first locking mechanism, the right collecting plate 1 and the left collecting plate 2 can be rotated and locked for up and down movement, so that the shape of the right collecting plate 1 and the left collecting plate 2 will not change. When the collecting plate is taken out of the oral cavity, the shape of the right collecting plate 1 and the left collecting plate 2 will not change, so that the silicone rubber will not be deformed, and the tooth shape sampling will not be changed, which can effectively solve the shortcomings of the prior art.

[0058] In this embodiment, the second locking mechanism includes an inner toothed ring 7 fixedly mounted at the free end of the first arc-shaped plate 101 and a matching member 6, the matching member 6 includes a shaft body and a movable outer toothed ring 603 connected to the shaft body in an up-and-down sliding manner, the movable outer toothed ring 603 cannot rotate but can only slide up-and-down, and the movable outer toothed ring 603 is engaged with the inner toothed ring 7. By sliding the movable outer toothed ring 603 up-and-down, the movable outer toothed ring 603 can be engaged and separated from the inner toothed ring 7, and by engaging the inner toothed ring 7 with the movable outer toothed ring 603, the rotation locking between the first arc-shaped plate 101 and the third arc-shaped plate 102, and the rotation locking between the second arc-shaped plate 201 and the fourth arc-shaped plate 202 can be achieved.

A first disc 1021 is integrally provided at the end of the third curved plate 102. A first rotating hole 1022 adapted to the upper shaft body 601 is provided at the center of the first disc 1021. The upper shaft body 601 is rotatably connected to the first rotating hole 1022. A first movable opening 1012 adapted to the first disc 1021 is provided at the free end of the first curved plate 101 (i.e., the end connected to the third curved plate 102). The first disc 1021 is located at the first movable opening. 1012, a third rotating hole 1014 is provided at the center of the first movable opening 1012 for the upper shaft body 601 to pass through, and the top of the upper shaft body 601 passes through the third rotating hole 1014 and the first rotating hole 1022 in sequence and is fixedly connected to the top of the first movable opening 1012; a second disc 2021 is integrally provided at the end of the fourth arc-shaped plate 202, and a second rotating hole 2022 adapted to another upper shaft body 601 is provided at the center of the second disc 2021, and the other upper shaft body 601 is rotatably connected to the second rotating hole 2022, and the free end of the second arc-shaped plate 201 (i.e. The end connected to the fourth arc plate 202 is provided with a second movable opening 2012 adapted to the second disc 2021, the second disc 2021 is located in the second movable opening 2012, the second movable opening 2012 is provided with a fourth rotating hole 2014 for the upper shaft body 601 to pass through, the top of the upper shaft body 601 passes through the fourth rotating hole 2014 and the second rotating hole 2022 in sequence and is fixedly connected to the top of the second movable opening 2012; the movable outer gear ring 603 is provided with a through hole 6031 adapted to the lower shaft body 602, because the lower shaft body 602 is a polygonal body , so that the movable outer gear ring 603 and the lower shaft body 602 will not rotate relative to each other, the bottom of the lower shaft body 602 is rotatably connected to the support plate 605 through the limit plate 604, and the bottom of the movable outer gear ring 603 is provided with a clamping groove 6032 that is engaged with the support plate 605. When the movable outer gear ring 603 slides upward into the inner gear ring 7, the top of the support plate 605 can be engaged with the clamping groove 6032 by rotating the support plate 605 upward, so that the movable outer gear ring 603 is limited in the inner gear ring 7 and will not move downward, so that the second locking mechanism can always be in a locked state. When the second locking mechanism needs to be released, it is only necessary to push the movable outer gear ring 603 upward, and under the action of the center of gravity, the support plate 605 can be automatically separated from the clamping groove 6032, and then under the action of gravity, the movable outer gear ring 603 will slide out of the inner gear ring 7, thereby realizing the release of the second locking mechanism.

[0060] In this embodiment, the thickness and height of the first curved plate 101 and the third curved plate 102 are the same, and the thickness and height of the second curved plate 201 and the fourth curved plate 202 are the same, that is, there is no height difference between the top surface and the bottom surface of the first curved plate 101 and the top surface and the bottom surface of the third curved plate 102, and there is no height difference between the top surface and the bottom surface of the second curved plate 201 and the top surface and the bottom surface of the fourth curved plate 202.
