Description

Technical Field

[0001] The present invention belongs to the technical field of building floor construction, and specifically relates to intelligent construction equipment and method for large-area floors. Background Art

[0002] A common problem after the construction of large-scale floor structures is cracks, which affect their use. Floor cracks refer to cracks within the concrete structure of the floor. Common cracks during construction are divided into those caused by the structure itself and those caused by external factors. Currently, there is a well-established construction experience in preventing cracks in large-scale cast-in-place concrete floors, such as optimizing concrete mix design, adopting compartmentalized pouring, selecting optimal pouring times, and using temperature-controlled concrete.

[0003] During the construction of large-area floors, extruded boards are usually installed in advance at the location where the separation joints are formed. The separation joints are formed using the extruded boards, such as CN118911377A. When pouring concrete, the impact of the concrete can easily cause the extruded boards to bend and deform, making it difficult to remove the extruded boards later. Summary of the Invention

The acting body is used to pressure the baffle plate to rotate upward, and the closing body is used to constrain the baffle plate at the discharge port.

[0016] According to a further optimized solution, the elastic locking structure includes an arc-shaped groove arranged on the top side of the bottom of the fixed seat and an elastic locking pin arranged on the bottom side of the top of the movable seat.

[0017] A further optimized solution is that the elastic locking pin includes a mounting hole set on the movable seat, an elastic part is installed in the mounting hole, a locking pin body is installed on the top of the elastic part, a restraining body is installed on the outside of the locking pin body, the restraining body is installed in the mounting hole and the locking pin body slides in the mounting hole and is partially exposed.

[0018] A further optimization solution is that the separation seam mold includes a lower base plate, two symmetrically distributed upper side plates are installed on the lower base plate, an airbag body is installed between the two upper side plates, the airbag body is provided with an air inlet and an exhaust port, the air inlet is connected to an external air pump through a pipeline and the pipeline is equipped with a switch valve, an electromagnetic diaphragm is installed at the exhaust port, a pressure sensor is provided inside the airbag body, and the pressure sensor and the electromagnetic diaphragm are electrically connected.

[0020] A further optimized solution is that the adjusting part includes an elastic telescopic rod rotatably mounted on one side of the two top plates that is relatively close to each other; an operating rod is slidably fitted in the sleeve, and a connecting sleeve and constraint rings distributed on both sides of the connecting sleeve are sleeved on the outer side of the operating rod, the connecting sleeve is rotatably mounted on the end of the elastic telescopic rod, a connector is provided at the end of the operating rod, a constraint groove is provided on the bottom plate, a guide groove for the connector to go down and a side constraint port communicated with the guide groove are provided on the side of the constraint groove, and the side constraint port is used to constrain the connector to go up.

[0021] A further optimization solution is that the construction equipment also includes a vibration platform installed on the top of the lifter in the two sets of walking components, and a drive shaft, a drive motor and a scraper plate are installed on the vibration platform. The drive motor drives the drive shaft to rotate, and a number of sleeves are installed on the vibration platform. A limit ring at the bottom, a spring distributed on the top of the limit ring and a vibration rod socketed in the spring are installed in the sleeve. A pressure ring is installed on the top of the vibration rod, and a number of cams are distributed on the drive shaft, and the cams are distributed on the top of the pressure ring.

[0022] A construction method for a large-area floor construction device, the steps are as follows:

[0023] Step 1. Preparation

[0024] The foundation structure is leveled to meet the design requirements, and a line is drawn on the foundation structure to obtain the construction boundary line of the separation seam formwork. A groove is cut at the construction boundary line, and the separation seam formwork is installed in the groove. By pressing the operating rod downward, the connector moves down along the guide groove. The elastic telescopic rod drives the top plate to fit in the groove position and the top is flush with the groove. After the top plate fits tightly in the groove position, the elastic telescopic rod is compressed and contracted, and the operating rod connector is rotated to enter the side restraint opening.

[0025] The air pump inflates the airbag until the two upper side plates are in the designed position, forming several sub-pouring bins, and the sides of the sub-pouring bins are coated with release agent;

[0026] Step 2: Side pouring

[0027] Place the walking assembly between the two upper side plates of the partition joint formwork, install the aggregate bin on the lifter, and cast-in-place concrete on both sides of the partition joint formwork through the aggregate bin and the sub-casting bin, and use the baffle plate to restrain the side position of the cast-in-place concrete;

[0028] During the pouring process of two adjacent separation bins, the moving assembly drives the aggregate bin to move, and the moving seat is blocked by the separation slit mold. The moving seat facing the movement direction moves upward and is driven downward by the rigid rope to move along the movement direction. When the moving seat facing the movement direction moves upward, the acting body acts on the baffle plate to rotate, and finally the closing body constrains the baffle plate to block the discharge port. At this time, the moving seat facing the movement direction and the corresponding fixed seat are constrained by the elastic locking pin, and the bottom of the moving seat facing the movement direction moves upward and is higher than the top of the separation slit mold.

[0029] The moving seat in the direction of movement is blocked by the separation seam mold. The moving seat in the direction of movement moves upward and is driven downward by the rigid rope to move the moving seat facing the direction of movement. When the moving seat in the direction of movement moves upward, the closing body separates from the baffle plate and passes through the acting body. Finally, the angle constraint body constrains the maximum opening angle of the baffle plate, and the cast-in-place concrete continues to be poured on both sides of the separation seam mold.

[0030] Step 3, middle part pouring

[0031] After pouring concrete on all the side parts of the sub-casting bins, pour concrete in the middle part of the sub-casting bins;

[0032] Step 4: Vibrate and level

[0033] After the concrete is poured in the sub-casting bin, the aggregate bin is removed and then the vibrating platform is moved horizontally in the sub-casting bin. While moving horizontally, the driving motor drives the driving shaft to rotate. The cam acts on the vibrating rod, and the vibrating rod, under the action of the spring, reciprocates up and down to vibrate the cast-in-place concrete, and finally it is leveled and scraped.

[0034] Step 5: Remove the vibration platform and moving components

[0035] After the scraping operation is completed, the vibration platform is dismantled and the moving components are removed, and the pressure value detected by the pressure sensor is reset to zero. During the curing and solidification of the concrete, if the pressure value detected by the pressure sensor exceeds 1-3% during the solidification period, the electromagnetic diaphragm opens the exhaust port to expel the gas inside the bladder until the pressure value detected by the pressure sensor returns to zero, until the concrete reaches the final design strength.

[0036] Step 6: Remove the separation seam mold

[0037] Open the exhaust port of the electromagnetic diaphragm to discharge the gas in the airbag and make it deflate. After deflation, the distance between the two upper side plates is smaller than the set separation gap. By rotating the operating lever, the connector is rotated to the bottom of the guide groove. The connector moves upward along the guide groove and detaches from the bottom plate until the top plate is detached from the slot and the distance between the two sides of the top plate is smaller than the separation gap width. Then remove the separation gap mold.

[0038] Step 7: Filling the seams

[0039] Pour elastic building sealing material into the separation joint.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. The present invention is an intelligent construction equipment that uses a walking component to walk along the partition seam formwork and simultaneously cast concrete on both sides of the partition seam formwork through a separate casting bin. By casting concrete on both sides of the partition seam formwork at the same time, the structure of the partition seam formwork can be stabilized in advance, avoiding the problem of displacement or distortion of the partition seam formwork caused by pouring concrete at one time.

[0042] 2. The present invention can automatically open and close the baffle plate and thus block the discharge port through the opening and closing parts. The automatic opening and closing of the discharge port can selectively avoid the casting at the position of the partition seam mold, thereby avoiding the walking obstacle of the walking component. At the same time, since a lifter is provided on the walking platform, the height of the aggregate bin can be adjusted, and the driving component drives the two walking wheels to rotate a certain angle, so that the two sets of walking wheels can move along the horizontal partition seam mold and the longitudinal partition seam mold of the sub-casting bin respectively, and then perform sub-casting on all sides of the sub-casting bin, and then perform middle pouring after the sub-casting. After the middle pouring, it is vibrated by a vibration platform and leveled by a scraper plate.

[0043] 3. The present invention adopts an elastic and retractable structure for the partition joint mold, and the elastic and retractable structure has the effect of adaptively adjusting the lateral pressure. It is different from the traditional elastic side mold structure in that: since the concrete will expand during the solidification period, the previous extruded board will be deformed by the lateral pressure, making the subsequent dismantling operation difficult. At the same time, when a certain lateral pressure is reached, the lateral pressure cannot be continued, which will cause the concrete to expand upward. After the upward expansion, it is easy to cause micro cracks in the assembly partition joint, or drive the extruded board upward, and finally cause the extruded board to be three-dimensionally twisted and deformed, which is not convenient for dismantling operations. In this case, the air pressure inside the airbag is dynamically maintained near the lateral pressure value of the leveled concrete. When expansion occurs, the exhaust port is automatically opened and closed by the electromagnetic diaphragm to complete the discharge of internal gas, and then dynamically maintain the dynamic lateral pressure force near the partition joint, thereby avoiding problems such as micro cracks caused by vertical expansion. After solidification is completed, it is also easy to dismantle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0063] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0064] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0065] Example 1

[0066] like Figure 1 、 2 , 3, 7, 9, 10, 11, and 12, a large-area floor intelligent construction equipment, comprising:

[0067] The partitioning slit mold 10 is fixed on the basic structure and is surrounded by a plurality of sub-casting bins 32;

[0068] The walking assembly 20 includes two walking wheels 21 that move on the inner side of the top of the partition slit die 10. A walking platform 22 is installed on the top of the two walking wheels 21. Two driving assemblies 23 are installed on the walking platform 22. The driving assemblies 23 drive the walking wheels 21 to rotate. A lifter 24 is installed on the top of the walking platform 22.

[0069] The casting assembly 30 includes a collection bin 31 detachably mounted on the top of the lifter 24. Two sub-casting bins 32 are symmetrically distributed on the side of the collection bin 31. The sub-casting bins 32 are communicated with the collection bin 31 and are provided with a discharge port at the bottom. A baffle plate 34 is rotatably mounted in the discharge port. An opening and closing member 33 is mounted on the side of the sub-casting bin 32. The opening and closing member 33 opens and closes the sub-casting bin 32 through the separation slit mold 10.

[0070] In actual implementation, the partitioning mold 10 is fixed on the base structure, and the base structure is enclosed into several sub-casting bins 32. Two sets of running wheels 21 are temporarily installed on the top of the partitioning mold 10. The running wheels 21 can move along the length direction of the partitioning mold 10. While moving, the two sides of the partitioning mold 10 are simultaneously cast through the sub-casting bins 32. After casting, the structural stability of the partitioning mold 10 is ensured, and the partitioning mold 10 has excellent impact resistance. When the casting of the partitioning mold 10 is completed, the driving component 23 (motor) drives one of the running wheels 21 through the gear transmission at the intersection of the partitioning mold 10, and the partitioning mold 10 is rotated to the position of the partitioning mold 10 perpendicular to it. By adjusting the two running wheels 21 to move along the corresponding partitioning mold 10, the other set of running wheels 21 is transferred into the partitioning mold 10 and moved along the partitioning mold 10. At the same time, the side of the partitioning mold 10 is cast, thereby completing the casting operation of the side of the entire sub-casting bin 32, ensuring the structural stability of the sub-casting bin 32. During the switching of the walking wheel 21 at the top of the two groups of partitioning slit molds 10, the opening and closing member 33 is always in the state of closing the discharge port with the baffle plate 34. During the movement along the entire partitioning slit mold 10, the opening and closing member 33 realizes automatic opening and closing operation through the action of the partitioning slit mold 10 perpendicular to the partitioning slit mold 10, thereby preventing the top position of the partitioning slit mold 10 from being cast, thereby ensuring the smooth operation of the walking component 20.

[0071] Example 2

[0072] On the basis of Example 1, in order to implement automatic opening and closing of the discharge port, the inventors made the following improvements:

[0073] like Figures 2 to 13 As shown, the opening and closing member 33 includes two fixed seats 35 installed on the side of the sub-pouring bin 32. The two fixed seats 35 are arranged parallel to the movement direction, and the bottoms of the two fixed seats 35 are both inclined upward. The bottoms of the two fixed seats 35 are slidably matched with movable seats 36, and the tops of the movable seats 36 are both inclined upward.

[0074] Several pulley bodies 37 are provided on the side of the sub-casting bin 32. The two movable seats 36 are connected by a rigid rope 38 on the side facing the direction of movement, and the two ends of the rigid rope 38 are wound around the pulley body 37.

[0075] An elastic locking structure is provided between the fixed seat 35 and the movable seat 36;

[0076] A vertical guide groove is provided on the movable seat 36 on the side facing the moving direction, and a slidable pressure member 39 is connected to the vertical guide groove via a spring. The pressure member 39 cooperates with the separation slot die 10 to automatically open and close the baffle plate 34.

[0077] like Figure 4 As shown, the pressure member 39 includes an angle constraint body 391, an action body 392 and a closing body 393. The angle constraint body 391 is arranged on one side of the movable seat 36 along the movement direction, and the action body 392 is arranged between the closing body 393 and the angle constraint body 391 and is set obliquely. The action body 392 is used to pressurize the baffle plate 34 to rotate upward, and the closing body 393 is used to constrain the baffle plate 34 at the discharge port.

[0078] The elastic locking structure includes an arc-shaped groove 351 provided on the top side of the bottom of the fixed seat 35 and an elastic locking pin provided on the bottom side of the top of the movable seat 36 .

[0079] The elastic locking pin includes a mounting hole set on the movable seat 36, an elastic member 352 is installed in the mounting hole, a locking pin body 353 is installed on the top of the elastic member 352, a restraining body 354 is installed on the outside of the locking pin body 353, the restraining body 354 is installed in the mounting hole and the locking pin body 353 is slidably fitted in the mounting hole and partially exposed.

[0080] When the casting assembly 30 passes the top of the partition slit mold 10, the top of the partition slit mold 10 will act on the movable seat 36 facing the direction of movement, and the movable seat 36 will move obliquely upward along the bottom of the fixed seat 35, and the movable seat 36 along the direction of movement will be driven downward by the rigid rope 38. The movable seat 36 along the direction of movement moves to the bottom of the corresponding fixed seat 35 and is matched with the elastic locking pin and the arc groove 351 to stabilize this state. During the upward movement of the movable seat 36 facing the direction of movement, the acting body 392 acts on the baffle plate 34 to rotate up and close the discharge port. The combined action of the closing body 393 and the spring will cause the baffle plate 34 to close the discharge port by the closing body 393 , thereby achieving that concrete will not be poured through the top of the separation seam mold 10. After the baffle plate 34 passes through the separation side mold 10, the movable seat 36 moves upward along the movement direction, and is driven downward by the rigid rope 38 to face the movement direction. The movable seat 36 moves to the bottom of the corresponding fixed seat 35 in the movement direction, and is matched with the elastic locking pin and the arc groove 351 to stabilize this state. During the period when the movable seat 36 moves to the bottom of the corresponding fixed seat 35 in the movement direction, the closing body 393 moves downward while the baffle plate 34 moves downward to open the baffle plate 34, and finally the angle constraint body 391 is constrained to the maximum angle of the baffle plate 34.

[0081] Example 3

[0082] On the basis of Example 2, in order to facilitate the formation of the partition seam and the removal of the partition seam mold 10, the inventors made the following improvements:

[0083] like Figure 2 、 3 As shown in Figures 5, 6, 7 and 14, the partition slit mold 10 includes a lower base plate 101, two symmetrically distributed upper side plates 102 are installed on the lower base plate 101, an air bag body 103 is installed between the two upper side plates 102, an air inlet 104 and an exhaust port 105 are provided on the air bag body 103, the air inlet 104 is connected to an external air pump 106 through a pipeline and the pipeline is equipped with a switch valve, an electromagnetic diaphragm 107 is installed at the exhaust port 105, a pressure sensor 108 is provided inside the air bag body 103, and the pressure sensor 108 and the electromagnetic diaphragm 107 are electrically connected.

[0084] The lower substrate 101 includes a bottom plate 111 and two top plates 112 that slide together above the bottom plate 111. The two top plates 112 are symmetrically distributed on the bottom plate 111. A sleeve 113 is installed inside the airbag body 103. An adjustment member 114 is installed inside the sleeve 113. The adjustment member 114 is used to adjust the outward movement of the two top plates 112 relative to the bottom plate 111.

[0085] The adjusting member 114 includes an elastic telescopic rod 115 rotatably mounted on one side of the two top plates 112 that is relatively close to each other; an operating rod 117 is slidably fitted in the sleeve 113, and a connecting sleeve 116 and constraint rings 119 distributed on both sides of the connecting sleeve 116 are sleeved on the outer side of the operating rod 117; the connecting sleeve 116 is rotatably mounted on the end of the elastic telescopic rod 115, and a connector 118 is provided at the end of the operating rod 117; a constraint groove 120 is provided on the bottom plate 111; a guide groove 121 for the connector 118 to descend and a side constraint port 122 communicated with the guide groove 121 are provided on the side of the constraint groove 120; the side constraint port 122 is used to constrain the connector 118 to ascend.

[0086] During implementation, when installing the partition mold 10, the lower base plate 101 is placed in the partition mold 10 installation groove on the basic structure, and the top of the top plate 112 is kept flush with the basic structure. The operating rod 117 is moved downward, and the connecting body 118 is moved along the guide groove 121 to the side constraint port 122 and rotated a certain angle. The elastic telescopic rod 115 will move the top plate 112 outward and fit tightly against the side of the installation groove. The air pump 106 supplies air from the air inlet 104 through the pipeline, and the air bag body 103 expands, driving the upper side plate 102 to move outward to the set position. The air inlet 104 is closed through the switch valve, and the air pump 106 is removed.

[0087] After pouring and leveling the concrete in the sub-pouring bin 32, the pressure measured by pressure sensor 108 is reset to zero. During the concrete setting period, the pressure in airbag 103 increases due to concrete expansion. Electromagnetic diaphragm 107 opens the exhaust port, dynamically maintaining the pressure in airbag 103 at zero, preventing the concrete from expanding upward while also preventing reverse compression and microcracks. When the concrete strength reaches the required level, electromagnetic diaphragm 107 opens, deflation of airbag 103. After deflation, operating lever 117 is reversed to reset top plate 112 until the top plate 112 and the concrete in the separation joint are completely separated.

[0088] Example 4

[0089] On the basis of Example 3, in order to facilitate the vibration and leveling operation, the inventors made the following improvements:

[0090] like Figures 15 to 18As shown, the construction equipment also includes a vibration platform 132 installed on the top of the lifter 24 in the two sets of walking components 20, and a drive shaft 124, a drive motor 123 and a scraper plate 125 are installed on the vibration platform 132. The drive motor 123 drives the drive shaft 124 to rotate, and a plurality of sleeves 126 are installed on the vibration platform 132. A limiting ring 127 at the bottom, a spring 129 distributed on the top of the limiting ring 127 and a vibration rod 128 socketed in the spring 129 are installed in the sleeve 126. A pressure ring 130 is installed on the top of the vibration rod 128, and a plurality of cams 131 are distributed on the drive shaft 124. The cams 131 are distributed on the top of the pressure ring 130.

[0091] After the concrete is poured in the side and middle parts of the casting bin 32, the walking assembly 20 walks along the length direction of the separation seam mold 10, and while the vibration platform 132 moves, the driving motor 123 drives the driving shaft 124 to rotate, drives the cam 131 to rotate, and the pressure ring 130 and the spring 129 cooperate to drive the vibration rod 128 to move up and down, thereby vibrating the concrete, and then the concrete is scraped and leveled by the scraper plate 125.

[0092] like Figures 1 to 18 As shown, a construction method of a large-area floor construction device, the steps are as follows:

[0093] Step 1. Preparation

[0094] The foundation structure is leveled to meet the design requirements, and a line is drawn on the foundation structure to obtain the construction boundary line of the partition seam mold 10. A groove is cut at the construction boundary line, and the partition seam mold 10 is installed in the groove. By pressing down the operating rod 117, the connector 118 moves down along the guide groove 121. The elastic telescopic rod 115 drives the top plate 112 to fit in the groove position and the top is flush with the groove. After the top plate 112 is tightly fitted in the groove position, the elastic telescopic rod 115 is compressed and contracted, and the operating rod 117 is rotated to allow the connector 118 to enter the side restraint opening 122.

[0095] The air pump 106 inflates the airbag 103 until the two upper side plates 102 are in the required design positions, forming a plurality of sub-pouring bins 32, and a release agent is applied to the sides of the sub-pouring bins 32;

[0096] Step 2: Side pouring

[0097] The walking assembly 20 is placed between the two upper side plates 102 of the partitioning slot mold 10, and the collecting bin 31 is installed on the lifting device 24. The cast-in-place concrete is poured on both sides of the partitioning slot mold 10 through the collecting bin 31 and the sub-pouring bin 32, and the side position of the cast-in-place concrete is restrained by the material blocking plate 34;

[0098] During the pouring process of two adjacent separation bins, the moving assembly drives the aggregate bin 31 to move, and the moving seat 36 is blocked by the separation slit mold 10. The moving seat 36 facing the movement direction moves upward and is driven downward by the rigid rope 38. When the moving seat 36 facing the movement direction moves upward, the acting body 392 acts on the baffle plate 34 to rotate upward, and finally the closing body 393 and the spring will work together to constrain the baffle plate 34 to block the discharge port. At this time, the moving seat 36 facing the movement direction and the corresponding fixed seat 35 are constrained by the elastic locking pin, and the moving seat 36 facing the movement direction moves upward, and its bottom is higher than the top of the separation slit mold 10;

[0099] The movable seat 36 along the movement direction is blocked by the partition slit mold 10. The movable seat 36 along the movement direction moves upward and is driven downward by the rigid rope 38 to face the movable seat 36 in the movement direction. When the movable seat 36 along the movement direction moves upward, the closing body 393 separates from the baffle plate 34 and passes through the acting body 392. Finally, the angle constraining body 391 constrains the maximum opening angle of the baffle plate 34, and the cast-in-place concrete continues to be poured on both sides of the partition slit mold 10.

[0100] Step 3, middle part pouring

[0101] After pouring concrete on the sides of all the sub-pouring bins 32, pour concrete in the middle of the sub-pouring bins 32;

[0102] Step 4: Vibrate and level

[0103] After the cast-in-place concrete in the sub-casting bin 32 is completed, the aggregate bin 31 is removed and then passed through the vibration platform 132. The vibration platform 132 moves horizontally in the sub-casting bin 32. While moving horizontally, the driving motor 123 drives the driving shaft 124 to rotate. The cam 131 acts on the vibrating rod 128. The vibrating rod 128, under the action of the spring 129, reciprocates up and down to vibrate the cast-in-place concrete, and finally undergoes leveling and scraping operations.

[0104] Step 5: Remove the vibration platform 132 and the moving components

[0105] After the screeding operation is completed, the vibration platform 132 is dismantled and the movable assembly is removed, and the pressure value detected by the pressure sensor 108 is reset to zero. During the curing and solidification of the concrete, if the pressure value detected by the pressure sensor 108 exceeds 1-3% during the solidification period, the electromagnetic diaphragm 107 opens the exhaust port 105 to exhaust the gas inside the bladder 103 until the pressure value detected by the pressure sensor 108 returns to zero, and the concrete reaches the final design strength.

[0106] Step 6: Remove the separation seam mold 10

[0107] The electromagnetic diaphragm 107 opens the exhaust port 105, and the gas in the airbag 103 is discharged to cause the airbag 103 to deflate. After the airbag 103 deflates, the distance between the two upper side plates 102 is smaller than the set separation gap. By rotating the operating lever 117, the connector 118 is rotated to the bottom of the guide groove 121. The connector 118 moves upward along the guide groove 121 and separates from the bottom plate 111 until the top plate 112 is separated from the notch and the distance between the two sides of the top plate 112 is smaller than the separation gap width. The separation gap mold 10 is then removed.

[0108] Step 7: Filling the seams

[0109] Pour elastic building sealing material into the separation joint.

The separation seam mold (10) is installed in the groove, and the operating rod (117) is pressed down until the connecting body (118) moves down along the guide groove (121). The elastic telescopic rod (115) drives the top plate (112) to fit at the groove position and the top is flush with the groove.
