In order not to affect the normal use of buildings and cement floors, buildings and cement floors that have been used for a long time are usually repaired. The main way to repair is to inject mud into the above gaps. In the past, injecting slurry into the gaps manually was time-consuming, labor-intensive and inefficient. With the development of science and technology, grouting machines dedicated to repairing gaps have appeared in the prior art. The grouting machine uses mechanical structures and electric equipment to inject slurry into the above gaps through a grouting head.

DETAILED DESCRIPTION

[0056] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0057] Example:

[0058] The grouting machine provided by the present invention is convenient for grouting in different directions. Figure 1 As shown, it includes a base 100, a mounting seat 200, a hopper 300, a conveying mechanism and a grouting head 500, wherein:

[0059] The base 100 is equipped with rollers 101, which facilitate the transportation of the entire grouting machine and the movement of the grouting machine. The mounting seat 200 is rotatably mounted on the base 100. A locking and unlocking structure is provided between the mounting seat 200 and the base 100. The locking and unlocking structure is used to lock the mounting seat 200 on the base 100 or unlock the mounting seat 200 from the base 100. When the mounting seat 200 is locked on the base 100, the mounting seat 200 cannot rotate on the base 100. When the mounting seat 200 is unlocked on the base 100, the mounting seat 200 can rotate on the base 100. Figure 1 As shown, a push handle is fixedly connected to the mounting seat 200 so that the user can push the filling machine to change its position as needed.

[0060] The above-mentioned conveying mechanism is installed on the above-mentioned mounting seat 200, and the above-mentioned hopper 300 is installed at the feed port of the conveying mechanism, the grouting head 500 is installed on the above-mentioned mounting seat 200, and the discharge port of the above-mentioned conveying mechanism is connected to the above-mentioned grouting head 500. The conveying mechanism is used to convey the slurry in the hopper 300 to the grouting head 500, and the grouting head 500 sprays the conveyed slurry.

[0061] Through the above structure, with the help of the roller 101 on the base 100, the entire grouting machine can be conveniently moved to a suitable position, and the mounting seat 200 of the conveying mechanism and the grouting head 500 is rotatably mounted on the base 100. When the position of the grouting head 500 needs to be changed, the locking and unlocking structure is controlled to unlock, and then the mounting seat 200 is rotated. Because the grouting head 500 is installed on the mounting seat 200, the position of the grouting head 500 can be changed when the mounting seat 200 is rotated. When the position of the grouting head 500 is adjusted to the right position, the locking and unlocking structure is locked, so that the mounting seat 200 cannot rotate on the base 100, and the grouting head 500 is stably in the position. Then, the conveying mechanism is started to convey the slurry in the hopper 300 to the grouting head 500, and the grouting head 500 sprays the slurry to the gap that needs to be repaired.

[0062] Compared with the grouting machine in the related art, the grouting machine provided by the present invention can not only change its position at will according to needs, but also can conveniently change the position of the grouting head 500 according to needs, so as to facilitate grouting in different directions.

[0063] An optional implementation of this embodiment is as follows: Figure 1 , Figure 2 as well as Figure 4 As shown, the base 100 is provided with a circular hole, and the bottom wall of the mounting seat 200 is provided with a circular shaft 202, and the circular shaft 202 is rotatably inserted in the circular hole, and the locking and unlocking structure is arranged between the circular shaft 202 and the base 100. The locking and unlocking structure can lock the circular shaft 202 on the base 100 or release the circular shaft 202 from the base 100. When the circular shaft 202 is locked on the base 100, the mounting seat 200 is locked on the base 100, and when the circular shaft 202 is unlocked from the base 100, the mounting seat 200 is unlocked from the base 100.

[0064] A planar thrust bearing is also installed between the mounting seat 200 and the base 100 to bear the weight of the mounting seat 200 and the entire body thereon, so that the friction between the mounting seat 200 and the base 100 is smaller, thereby making it easier for the mounting seat 200 to rotate on the base 100.

[0065] Of course, an electric turntable can also be installed between the mounting base 200 and the base 100, or the electric turntable can be installed on the base 100, and the mounting base 200 can be installed on the turntable of the electric turntable, and the electric turntable can be used to drive the mounting base 200 to rotate on the base 100. Of course, in this case, a battery needs to be installed on the base 100 to power the electric turntable.

[0066] An optional implementation of this embodiment is as follows: Figure 2 , Figure 3 as well as Figure 4 As shown, the locking and unlocking structure includes a locking gear 203, a clamping plate 204 with clamping teeth 205, and a first driving assembly, wherein:

[0067] A mounting groove is provided on the top surface of the base 100, and a circular hole is provided at the bottom of the mounting groove, that is, the circular hole is located at the bottom of the mounting groove. When the circular shaft 202 is inserted into the circular hole, it will pass through the mounting groove. The locking gear 203 is sleeved on the circular shaft 202 and fixed by welding or keying with the circular shaft 202, and the locking gear 203 is rotatably placed in the mounting groove. The clamping plate 204 is movably placed in the mounting groove, and the clamping plate 204 is located on the side of the locking gear 203. A first driving assembly is provided between the clamping plate 204 and the base 100, and the first driving assembly is used to drive the clamping plate 204 to approach or move away from the locking gear 203. When the clamping plate 204 approaches the locking gear 203, the clamping teeth 205 mesh with the locking gear 203 to lock the circular shaft 202; when the clamping plate 204 moves away from the locking gear 203, the clamping teeth 205 separate from the locking gear 203 to unlock the circular shaft 202. It is worth noting that the latching teeth 205 will be fully meshed with the locking gear 203 only when the latching plate 204 is closest to the locking gear 203 .

[0068] In this structure, the locking gear 203 is locked by meshing the locking gear 203 with the locking teeth 205 on the clamping plate 204, that is, it cannot rotate. The first driving assembly can be any form of driving mechanism, as long as it can drive the clamping plate 204 to move closer to and away from the locking gear 203. For example, the first driving assembly can be an electric telescopic rod or a linear motor. As the best implementation of this embodiment, the first driving assembly includes a guide column 206, a first compression spring 207, a connecting rod 208 and a driving rod 209, wherein:

[0069] The above-mentioned card plate 204 is a flat plate, and the card tooth 205 is arranged on one side plate surface of the card plate 204. The guide column 206 is welded and fixed or integrally formed on the other side plate surface of the card plate 204, and the guide column 206 is perpendicular to the card plate 204. A guide hole is opened on the groove wall of the installation groove, and the guide column 206 is slidably inserted in the guide hole. When the guide column 206 enters the guide hole, the card plate 204 is away from the locking gear 203. When the guide column 206 extends out of the guide hole, the card plate 204 is close to the locking gear 203. In order to make the guide column 206 more smoothly enter and exit the guide hole and make the card plate 204 approach / move away from the locking gear 203 more smoothly, in this embodiment, two guide columns 206 are fixedly connected to the card plate 204. Correspondingly, two guide holes are opened on the groove wall of the installation groove, and the two guide columns 206 are respectively slidably inserted in the two guide holes. The first compression spring 207 is installed in the guide hole, and the two ends of the first compression spring 207 are respectively in contact with the guide column 206 and the bottom of the guide hole. In this way, when the clamping plate 204 is not subjected to other external forces, with the help of the first compression spring 207, the clamping plate 204 is always in a position close to the locking gear 203, that is, the clamping tooth 205 on the clamping plate 204 is always in contact with the locking gear 203.

[0070] One end of the connecting rod 208 is hinged to one side of the card plate 204. Specifically, a first hinge seat is provided on one side of the card plate 204, and one end of the connecting rod 208 is hinged to the first hinge seat. A through hole penetrating the outer wall of the mounting seat 200 is provided on the groove wall of the mounting groove. The driving rod 209 is slidably inserted into the through hole. One end of the driving rod 209 is placed in the mounting groove and hinged to the other end of the connecting rod 208. Specifically, a second hinge seat is provided on one end of the driving rod 209, and the other end of the connecting rod 208 is hinged to the second hinge seat. The other end of the driving rod 209 is placed outside the base 100.

[0071] In this embodiment, the number of the clamping plates 204 may be one or more, and correspondingly, the number of the connecting rods 208 may be one or more. Figure 2 As shown, in this embodiment, there are two card plates 204, and the two card plates 204 are respectively arranged on both sides of the locking gear 203. Each card plate 204 is provided with two guide pillars 206. There are two connecting rods 208, and each card plate 204 is connected to the above-mentioned driving rod 209 through a connecting rod 208.

[0072] like Figure 2As shown, the connecting rod 208 and the driving rod 209 actually form a crank connecting rod 208 mechanism. When the driving rod 209 moves into the installation slot, because the guide post 206 is slidably inserted in the guide hole, the driving rod 209 drives the connecting rod 208 to press the card plate 204 sideways, so that the card plate 204 is away from the locking gear 203 to achieve unlocking, and the guide post 206 presses the first compression spring 207; when the driving rod 209 moves out of the installation slot, the first compression spring 207 pushes the guide post 206 to make the card plate 204 close to the locking gear 203, and when the driving rod 209 moves outward to the extreme point, the card plate 204 moves to the position closest to the locking gear 203, and the locking teeth 205 on the card plate 204 mesh with the locking gear 203 to achieve locking.

[0073] Through the first driving assembly of the above-mentioned form, when the user pushes the driving rod 209 inward, the connecting rod 208 will press the card plate 204 toward the side and make the card plate 204 away from the locking gear 203. At this time, the locking teeth 205 on the card plate 204 can be separated from the locking gear 203, thereby unlocking the locking gear 203, the round shaft 202 and the mounting seat 200. In this process, the guide column 206 moves toward the inside of the guide hole and presses the first compression spring 207. When the user releases the driving rod 209, under the action of the first compression spring 207, the guide column 206 will move toward the side outside the guide hole, thereby pushing the card plate 204 close to the locking gear 203, until the locking teeth 205 on the card plate 204 mesh with the locking gear 203. Therefore, the locking and unlocking structure of the above-mentioned form has the advantages of simple structure and convenient use, and is a purely mechanical structure, does not require the use of electricity, and is less prone to damage.

[0074] Optionally, in this embodiment, if Figure 2 and Figure 3 As shown, a pin hole is provided on the outer wall of the middle part of the driving rod 209, and a sliding hole is provided on the hole wall of the through hole. A lock pin 210 adapted to the pin hole is slidably installed in the sliding hole. A second compression spring 211 is also installed in the sliding hole. The two ends of the second compression spring 211 are respectively in contact with the lock pin 210 and the bottom of the sliding hole. A through groove is provided on the hole wall of the sliding hole. A lever 212 connected to the lock pin 210 is slidably installed in the through groove. When the lever 212 is pressed, the lock pin 210 moves toward the sliding hole and further compresses the second compression spring 211. When the driving rod 209 moves outward to the extreme point, the lock pin 210 is inserted into the pin hole. When the lock pin 210 is inserted into the pin hole, the driving rod 209 is locked on the mounting seat 200. The specific usage scenarios are as follows:

[0075] When the driving rod 209 moves outward to the extreme point, correspondingly, the above-mentioned card plate 204 moves to the position closest to the above-mentioned locking gear 203. At this time, the locking tooth 205 on the card plate 204 engages with the locking gear 203. At this moment, the above-mentioned locking pin 210 automatically enters the above-mentioned pin hole under the action of the second compression spring 211. At this time, the locking pin 210 locks the driving rod 209 on the base 100, and the locking tooth 205 locks the above-mentioned locking gear 203. In this way, the locking and unlocking structure can be made more stable when locked, thereby preventing the mounting seat 200 from rotating accidentally on the above-mentioned base 100 during the grouting process. If it is necessary to rotate the mounting base 200 on the base 100 to change the position of the grouting head 500, first press the lever 212 downward, so that the lever 212 drives the locking pin 210 to move downward, so that the locking pin 210 comes out of the pin hole, thereby unlocking the driving rod 209, and then push the driving rod 209 inward to disengage the locking teeth 205 on the clamping plate 204 from the locking gear 203.

[0076] An optional implementation of this embodiment is as follows: Figure 1 , Figure 5 , Figure 6 as well as Figure 7 As shown, a scraper 600 is installed in the hopper 300, and the scraper 600 is in contact with the inner wall of the hopper 300. A second drive assembly is also installed in the hopper 300, and the second drive assembly is connected to the scraper 600, and the second drive assembly is used to drive the scraper 600 to move in the hopper 300. With the help of the second drive assembly, the scraper 600 can be driven to move in the hopper 300, and the scraper 600 is in contact with the inner wall of the hopper 300. When the scraper 600 moves, the slurry attached to the inner wall of the hopper 300 can be scraped off, which can effectively prevent the slurry from being attached to the inner wall of the hopper 300 and solidifying.

[0077] Optionally, the hopper 300 in this embodiment has a quadrangular pyramidal outline and has four inner side walls connected end to end. There are four scrapers 600 , which are respectively attached to the four inner side walls of the hopper 300 . The second driving assembly includes four lead screws 601 and an electric motor 602. Mounting blocks 603 are provided on the four outer walls of the hopper 300. The four lead screws 601 are rotatably inserted into the mounting blocks 603 around the hopper 300. Two adjacent lead screws 601 are connected by a gear transmission pair 604. The power output shaft of the electric motor 602 is connected to one of the lead screws 601. A threaded sleeve 605 is screwed on each lead screw 601. The four threaded sleeves 605 are connected to a connecting block 606. A slide groove is provided on the four side walls of the hopper 300. The length direction of the slide groove is parallel to the lead screw 601. Four connecting blocks 606 are slidably placed in the four slide grooves, and the four connecting blocks 606 are respectively connected to the four scrapers 600. In this way, when the above-mentioned motor 602 is started, it can drive one of the lead screws 601 to rotate. Of course, the lead screw 601 can be connected to the corresponding mounting block 603 through a bearing, so that the rotation of the lead screw 601 is more flexible. When one of the lead screws 601 rotates, the threaded sleeve 605 thereon will drive the corresponding connecting block 606 to translate, and then drive the corresponding scraper 600 to move inside the hopper 300. Moreover, when one of the lead screws 601 rotates, through the action of multiple gear transmission pairs 604, the four lead screws 601 will rotate synchronously, thereby driving the four scrapers 600 to move at the same time.

[0078] Of course, if the lengths of the four inner side walls of the hopper 300 are different, it is necessary to control the transmission ratios of different transmission pairs, thereby controlling the moving speeds of the four scrapers 600, so that each scraper 600 takes the same time to move from one side to the other side of the corresponding inner wall. After the scraper 600 moves from one side of the inner wall to the other side, the motor 602 rotates in the opposite direction, so that the scraper 600 moves from the other side of the inner wall to the one side.

[0079] In addition, the gear transmission pair 604 may not be used, but each lead screw 601 may be connected to a motor 602, that is, the number of the motors 602 is four, and the four motors 602 respectively drive the four lead screws 601 to rotate, thereby allowing the four scrapers 600 to move independently in the hopper 300.

[0080] In addition, if the shape of the above-mentioned hopper 300 is conical, then only a scraper 600 needs to be installed on the inner wall of the hopper 300. In this case, a circular track needs to be set on the top surface of the hopper 300, and an electric walking trolley is set on the circular track. The electric walking trolley is connected to the above-mentioned scraper 600, and the scraper 600 is driven to move in the hopper 300 by the electric walking trolley.

[0081] An optional implementation of this embodiment is as follows: Figure 1 , Figure 8 and Fig. 9 As shown, a support 700 extending out of the base 100 is provided on the mounting seat 200, and a through hole is provided on the support 700 that penetrates the upper and lower surfaces thereof, and the grouting head 500 is inserted into the through hole. A fixed clamping plate 701 located on one side of the through hole is provided on the top surface of the support 700, and a sleeve 702 is also provided on the top surface of the support 700, in which a round rod 703 is rotatably installed, and a stud located outside the sleeve 702 is provided at both ends of the round rod 703, and the threads of the two studs are opposite, and each stud is screwed to a block 704, and one side surface of the block 704 is in contact with the top surface of the base 100, and each block 704 is hinged with a straight rod 705, and one end of the two straight rods 705 away from the corresponding block 704 is hinged to a movable clamping plate 706, and the grouting head 500 is clamped to the fixed clamping plate 701 through the movable clamping plate 706.

[0082] Through the above structure, when the round rod 703 is rotated, the two blocks 704 can be driven to translate on the round rod 703, and the movable splint 706 can be pushed and pulled through the two straight rods 705. When the blocks 704 move to the end surface of the sleeve 702, the two blocks 704 move to the closest position. At this time, the two straight rods 705 push the movable splint 706 to the farthest position. At this time, the distance between the movable splint 706 and the fixed splint 701 is the smallest. If there is a grouting head 500 between the movable splint 706 and the fixed splint 701, the movable splint 706 will clamp the grouting head 500 to the fixed splint 701. Optionally, the fixed splint 701 and the movable splint 706 are both semicircular plates. When the distance between the two is the smallest, the fixed splint 701 and the movable splint 706 are butt-jointed to form a complete circular tube. A connection hole is provided at one end of the round rod 703, and the connection hole is used to connect an extension rod perpendicular to the round rod 703, so as to facilitate the rotation of the round rod 703. When the movable clamp 706 and the fixed clamp 701 clamp the grouting head 500, the screw connection pre-tightening force between the screw and the block 704 can achieve locking. If the grouting head 500 needs to be removed, the extension rod is inserted into the connection hole and the round rod 703 is rotated in the opposite direction. At this time, the two blocks 704 move in a direction away from each other, so that the movable clamp 706 is pulled by the straight rod 705, so that the movable clamp 706 releases the grouting head 500. The block 704 fits with the base 100, so that the block 704 can translate on the base 100, but the block 704 cannot rotate with the stud.

[0083] The movable clamping plate 706, the fixed clamping plate 701, the round rod 703, the block 704 and the connecting rod 208 in this embodiment actually constitute a clamping structure for clamping the grouting head 500. Of course, the clamping structure can be in the form of a seat tube clamp, for example.

[0084] An optional implementation of this embodiment is as follows: Figure 1 , Figure 8 as well as Fig.10 As shown, the above-mentioned conveying mechanism includes a feed pipe 400, an auger shaft and a feed motor 800. The feed pipe 400 and the feed motor 800 are both mounted on the mounting seat 200 through a bracket 201. The hopper 300 is mounted on the outer wall of the feed pipe 400 and is located above the feed pipe 400. The auger shaft is rotatably placed in the feed pipe 400. The power output shaft of the feed motor 800 is connected to the auger shaft. The grouting head 500 is connected to the feed pipe 400 through a hose 900. When the feed motor 800 is powered on, the auger shaft is driven to rotate in the feed pipe 400. After the slurry in the hopper 300 falls into the feed pipe 400, it can be transported to the hose 900 under the action of the auger shaft, and then transported to the grouting head 500 after being guided by the hose 900. Of course, this form of conveying mechanism is the same as the prior art, and the improvement point of this patent is not this, so it will not be described in detail here.

[0085] A plurality of clamping rings 707 are installed on the top and bottom surfaces of the support 700. The clamping rings 707 are used to fix the hose 900 on the support 700, so that the hose 900 is stored on the support 700, so that the hose 900 is distributed in an orderly manner on the support 700, avoiding the hose 900 being in a disorderly manner.

[0086] Alternatively, if Fig.10 As shown, a vertical slide is provided on the surface of the support 700, and the clamping ring 707 includes a straight section and a bent section. The bent section is provided at one end of the straight section, and the straight section is slidably placed on the vertical slide. A locking cavity located at the end of the vertical slide is provided in the support 700, and a first wedge-shaped block 708 is provided at the other end of the straight section, and the first wedge-shaped block 708 is placed in the locking cavity;

[0087] The support 700 is also provided with a transverse slideway located on the side wall of the lock cavity, in which a slide bar 709 is slidably installed, and a second wedge block 710 cooperating with the first wedge block 708 is provided at one end of the slide bar 709 close to the lock cavity. A plug post 711 is provided at one end of the slide bar 709 away from the lock cavity, and a socket located at the end of the transverse slideway is also provided in the support 700, in which the plug post 711 is slidably inserted, and a third compression spring 712 is installed in the socket, and the two ends of the third compression spring 712 are respectively abutted against the plug post 711 and the bottom of the socket, and the surface of the support 700 is also provided with an unlocking slideway connected to the transverse slideway, in which an unlocking shaft 713 is slidably installed, and a third wedge block 714 is provided at one end of the unlocking shaft 713 close to the slide bar 709, and a fourth wedge block 715 cooperating with the third wedge block 714 is provided on the slide bar 709.

[0088] In fact, the support 700 of the above structure is formed by stacking a central plate and two panel plates, the two panels are respectively placed on the upper and lower sides of the central plate, and the panels are fixed to the support 700 by bolts. The above vertical slide and unlocking slide are both opened on the above panels, and the above lock cavity, the above horizontal slide and the above socket are all opened on the above central plate.

[0089] This embodiment is described by taking a retaining ring 707 and an unlocking shaft 713 as an example. Fig.10During installation, firstly, the straight section of the clamp ring 707 is passed through the vertical slideway on the panel, and then the first wedge block 708 is welded and fixed to the end of the straight section, then the unlocking shaft 713 is connected to the unlocking slideway, and then the third wedge block 714 is welded and fixed to one end of the unlocking shaft 713, and then the third compression spring 712 is installed into the above-mentioned plug hole, and then the slide bar 709 is placed in the horizontal slideway, so that the plug rod on the slide bar 709 is inserted into the above-mentioned plug hole, and the fourth wedge block 715 on the slide bar 709 is facing upward and the second wedge block 710 is from the side. The panels are then stacked on the sides of the center plate and fixed with bolts. At this time, the first wedge block 708 is located above the second wedge block 710, and the third wedge block 714 is located above the fourth wedge block 715. Under the action of the third compression spring 712, the second wedge block 710 is blocked under the first wedge block 708. In this case, there is a gap between the retaining ring 707 and the surface of the support 700. The user can insert the hose 900 through the gap and then push the retaining ring 707 into the support 700. When the retaining ring 707 moves toward the support 700, the first wedge block 708 presses the second wedge block 710 downward. Because of the third compression spring 712, when the second wedge block 710 is compressed, it will push the sliding rod 709 laterally, thereby causing the insertion rod to move toward the insertion hole and further compress the third compression spring 712. At the same time, the second wedge block 710 will also move laterally until the second wedge block 710 can no longer support the first wedge block 708 from below. Then, the first wedge block 708 and the retaining ring 707 will move downward, and the first wedge block 708 will enter the lock cavity. The first wedge block 708 entering the lock cavity can no longer resist the above-mentioned second wedge block 710 from the other side. Therefore, after the first wedge block 708 enters the lock cavity, under the elastic force of the above-mentioned third compression spring 712, the sliding rod 709 will be driven to move toward the other side, thereby causing the second wedge block 710 to move toward the other side until the second wedge block 710 moves to block the top of the first wedge block 708. At this time, since the second wedge block 710 blocks the top of the first wedge block 708, the first wedge block 708 is located in the above-mentioned lock cavity, that is, the retaining ring 707 is locked on the above-mentioned support 700. Of course, in this case, the above-mentioned retaining ring 707 moves down to fit with the top surface of the support 700, that is, the gap between the retaining ring 707 and the support 700 is zero, and then the retaining ring 707 is used to clamp the hose 900 on the surface of the support 700.

[0090] Of course, when the slide bar 709 slides toward one side in the transverse slideway, the fourth wedge-shaped block 715 will also slide toward one side. Fig.10As shown, the third wedge block 714 on the unlocking shaft 713 is placed above the fourth wedge block 715 and cooperates with the fourth wedge block 715. Therefore, when the fourth wedge block 715 slides to one side, the third wedge block 714 and the unlocking shaft 713 will move downward under the action of their own weight; when the cross bar slides to the other side in the horizontal slide, the fourth wedge block 715 will also slide to the other side and push the third wedge block 714 and the unlocking shaft 713 to move upward.

[0091] If it is necessary to remove the first wedge block 708 inserted into the lock cavity, a pressing force is applied to the unlocking shaft 713, so that the unlocking shaft 713 drives the third wedge block 714 to move downward, and the third wedge block 714 moving downward will squeeze the fourth wedge block 715 downward, so that the fourth wedge block 715 drives the slide bar 709 to move to one side in the horizontal slide, so that the second wedge block 710 at the end of the slide bar 709 is moved away from the position of resisting the first wedge block 708. At this time, the retaining ring 707 can be pulled up again.

[0092] Preferably, Fig.10 As shown, a retaining ring 716 is provided on the inner wall of one end of the vertical slideway, a baffle 717 is provided in the middle of the straight section of the clamping ring 707, and a tension spring 718 is provided on the straight outer sleeve of the clamping ring 707, one end of the tension spring 718 is fixedly connected to the retaining ring 716, and the other end of the tension spring 718 is fixedly connected to the baffle 717. It is worth noting that the retaining ring 716 and the panel are integrally formed, and the baffle 717 is welded and fixed to the straight section of the clamping ring 707, and when assembling, the baffle 717 needs to be welded to the straight section of the clamping ring 707 first, and then the first wedge block 708 is welded.

[0093] With the help of the above-mentioned tension spring 718, when the retaining ring 707 is pressed down to the first wedge block 708 to enter the lock cavity, the baffle 717 further stretches the above-mentioned tension spring 718. When the unlocking shaft 713 is pressed so that the second wedge block 710 no longer resists above the first wedge block 708, the elastic force of the above-mentioned tension spring 718 will pull the above-mentioned retaining ring 716 upward, so that when the above-mentioned unlocking shaft 713 is pressed, the retaining ring 707 can automatically pop up.

[0094] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
