Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grouting construction equipment, in particular to a basement waterproof construction device. BACKGROUND

[0002] In basement engineering, waterproofing is a core link related to structural safety and use function. Due to the deep burial of the basement underground, it is easily affected by factors such as underground water pressure, concrete shrinkage cracks, improper construction joints, etc., and leakage problems are prone to occur. The grouting machine is the key equipment for solving the waterproofing problem of the basement, which can quickly seal existing leakage points and prevent potential hazards.

[0003] For example, Chinese patent CN208502312U discloses a high-pressure jet grouting machine, which includes a machine body, an electric drill and a hopper are arranged on the machine body, a grout outlet pipe is arranged on the side of the machine body, a high-pressure pipe is connected to the grout outlet pipe through a pipe connector, a cow head is arranged at the end of the high-pressure pipe, a pouring switch is arranged on the high-pressure pipe, universal wheels are arranged on the bottom of the machine body, a protection pipe is arranged on the grout outlet pipe, the high-pressure pipe is arranged in the protection pipe, the pouring switch and the cow head extend out of the protection pipe, the protection pipe and the high-pressure pipe are pulled to drive the entire machine body to move on the ground through the universal wheels, and the cow head fills the gap, so that the entire frame fills the gap while moving.

[0004] However, the grouting pipe in the above scheme is freely arranged under the action of its own weight, and the claw piece and the grouting nail also need to overcome the action of the weight, which easily leads to unstable connection at the connection, and the vibration during work leads to the risk of shaking or loosening of the two, which easily leads to sealing failure and further causes the risk of partial leakage of the grout. SUMMARY

[0017] The present invention provides a rotating sleeve and a first slide rail and a second slide rail on the outer periphery of the rotating sleeve, so that the clamping jaw sleeve drives the elastic clip to rotate circumferentially when it moves axially, thereby avoiding continuous force on a single elastic clip and evenly distributing wear.

[0018] The present invention provides an adjustment component, which adjusts the initial position of the clamping ring and changes the clamping force of the elastic clip (the closer the clamping ring is to the hinge head, the greater the clamping force). This can adapt to fatigue deformation of the elastic clip caused by long-term use, maintain a stable clamping effect, and eliminate the need for frequent replacement of components.

[0019] The present invention provides arcs at both ends of the elastic clip, so that when one end is severely worn, it can be exchanged for use, thereby further extending the service life of the component. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The basement waterproof construction device provided by the present application will be described below with reference to Figures 1-15

[0026] A basement waterproof construction device is suitable for basement waterproof operation, comprising a grouting machine body 100, a grouting pipe 110 connected to the grouting machine body 100, and grout in the grouting machine body 100 being extruded into the grouting pipe 110 under pressure, the grouting pipe 110 being used for conveying grouting liquid, further comprising a grouting nail 120, the grouting nail 120 being used for being inserted into a wall body in need of grouting and being inserted into a grouting port of the wall body, one end of the grouting nail 120 being inserted into the wall body, a hinged joint 130 being arranged on the other end of the grouting nail 120, a tallow head 200 being detachably connected to the hinged joint 130, one end of the tallow head 200 being connected to the hinged joint 130 of the grouting nail 120, and the other end of the tallow head 200 being connected to the grouting pipe 110, the grouting pipe 110 injecting grouting liquid into the wall body through the tallow head 200 and the grouting nail 120 to fill cracks and gaps in the wall body. ​

[0027] The butter head 200 comprises a shell 210, one end of the shell 210 is connected to the grouting pipe 110, the inside of the shell 210 is axially elastically slid with a ventilation sleeve 220, the inside of the ventilation sleeve 220 has a channel, the channel is communicated with the grouting pipe 110, the outer periphery of the ventilation sleeve 220 is uniformly distributed with a plurality of elastic clamping pieces 230, in the embodiment, there are four, one end of the plurality of elastic clamping pieces 230 has a curvature, the outer periphery of the plurality of elastic clamping pieces 230 is provided with a clamping ring 240, the clamping ring 240 is used for clamping the plurality of elastic clamping pieces 230 together, when the operator connects the grouting nail 120 and the butter head 200, the hinged joint 130 of the grouting nail 120 is abutted on one end of the ventilation sleeve 220, at this time, the plurality of elastic clamping pieces 230 on the outer periphery of the ventilation sleeve 220 has the end with the curvature and can clamp the hinged joint 130, when the plurality of elastic clamping pieces 230 are clamped together through the clamping ring 240, the end with the curvature of the elastic clamping piece 230 will be deformed to tightly clamp on the hinged joint 130, thereby completing the connection of the grouting nail 120 and the butter head 200.

[0028] When the grouting machine body 100 works normally, because the grouting pipe 110 and the butter head 200 are connected together, and the grouting nail 120 has a certain height on the wall surface, the grouting pipe 110 will be sagged at the connection position of the butter head 200 and the grouting nail 120 under the action of gravity, causing the connection position of the butter head 200 and the grouting nail 120 to be inclined under the action of gravity of the grouting pipe 110, and the vibration generated when the grouting machine body 100 works will be transmitted to the butter head 200 and the grouting nail 120 through the grouting pipe 110, thereby further affecting the sealing performance of the connection position of the butter head 200 and the grouting nail 120.

[0029] Based on this, the clamping jaw sleeve 250 is axially elastically slid on one end of the shell 210 away from the grouting pipe 110, and the clamping groove 140 is arranged on one end of the grouting nail 120 close to the hinged joint 130, the clamping jaw sleeve 250 can clamp the clamping groove 140 after the plurality of elastic clamping pieces 230 clamp the hinged joint 130, so that the hinged joint 130 and the clamping groove 140 of the grouting nail 120 are clamped, the connection position of the grouting nail 120 and the butter head 200 has two, compared with the prior art in which only the hinged joint 130 is connected with the butter head 200, the two connection positions can improve the connection strength of the butter head 200 and the grouting nail 120, and reduce the influence of the gravity of the grouting pipe 110 on the connection of the butter head 200 and the grouting nail 120.

[0030] It can be understood that when only the hinge joint 130 of the grouting nail 120 is connected with the plurality of elastic clamping pieces 230 of the butter head 200, the connection position of the grouting nail 120 and the butter head 200 will be inclined, at this time, the clamping effect of the plurality of elastic clamping pieces 230 on the hinge joint 130 is poor, and the present application sets the clamping groove 140 between the hinge joint 130 and the grouting nail 120, and the clamping jaw sleeve 250 is arranged on the shell 210 of the butter head 200, the clamping jaw sleeve 250 is clamped in the clamping groove 140 to clamp the grouting nail 120 again, and the plurality of elastic clamping pieces 230 are clamped on the hinge joint 130 at the same time, so that the connection position of the grouting nail 120 and the butter head 200 has two, at this time, the axis of the grouting nail 120 and the butter head 200 coincides, thereby avoiding the inclination of the connection position of the butter head 200 and the grouting nail 120, and improving the sealing performance of the connection position of the butter head 200 and the grouting nail 120.

[0031] Specifically, as shown in Figure 12 the clamping jaw sleeve 250 has a plurality of elastic clamping jaws at one end, the plurality of elastic clamping jaws have elasticity, the diameter of the plurality of elastic clamping jaws is slightly smaller than the diameter of the clamping groove 140, so that the elastic clamping jaws can clamp the clamping groove 140 when located at the position of the clamping groove 140, the other end of the clamping jaw sleeve 250 is cylindrical, when the operator connects the butter head 200 and the grouting nail 120 together, the hinge joint 130 of the grouting nail 120 will abut against the clamping jaw sleeve 250, when the operator pushes the butter head 200, the clamping jaw sleeve 250 will axially elastically move, when the force of the operator pushing the butter is greater than the force of the elastic movement, the hinge joint 130 passes through the elastic clamping jaws of the clamping jaw sleeve 250, the hinge joint 130 abuts against one end of the plurality of elastic clamping pieces 230 having an arc, the operator continues to force, so that the hinge joint 130 pushes the one end of the plurality of elastic clamping pieces 230 having an arc to deform, the hinge joint 130 is gradually clamped by the plurality of elastic clamping pieces 230, at the same time, the clamping jaw sleeve 250 moves axially relative to the hinge joint 130, the clamping jaw sleeve 250 gradually approaches the clamping groove 140, when the hinge joint 130 is completely clamped and fixed by the plurality of elastic clamping pieces 230, the clamping jaw sleeve 250 is clamped in the clamping groove 140, thereby completing the connection of the butter head 200 and the grouting nail 120.

[0032] In further embodiments, due to the gravity of the grouting pipe 110, the force of the hinge joint 130 on the plurality of elastic clamping pieces 230 is different, if used for a long time without changing the position, it will cause the same elastic clamping piece 230 to continuously bear a larger force, resulting in increased wear and tear and affecting the service life, therefore, in order to solve this problem, the plurality of elastic clamping pieces 230 are rotationally arranged, so that the position of the plurality of elastic clamping pieces 230 inside the butter head 200 will change every time the operator installs the butter head 200, thereby avoiding the situation that a certain elastic clamping piece 230 continuously bears force.

[0033] Specifically, the clamping ring 240 is in sliding connection with the plurality of elastic clamping pieces 230 in the peripheral direction, so that the clamping ring 240 and the plurality of elastic clamping pieces 230 cannot rotate relative to the peripheral direction, a plurality of arc-shaped through grooves 241 are formed in the side wall of the clamping ring 240, the plurality of elastic clamping pieces 230 are respectively arranged in the plurality of arc-shaped through grooves 241 in a sliding manner, a rotating sleeve 260 is arranged on the outer periphery of the clamping ring 240 in the axial direction, the outer periphery of the clamping ring 240 has a rectangular block 242, the inner periphery of the rotating sleeve 260 is provided with a sliding groove 261 extending in the axial direction, the rectangular block 242 is located in the sliding groove 261, and the outer periphery of the rotating sleeve 260 is in rotating connection with the inner periphery of the clamping jaw sleeve 250. The rotating sleeve 260 can drive the clamping ring 240 to rotate around the axis thereof, and when the clamping ring 240 rotates around the axis thereof, the plurality of elastic clamping pieces 230 can be driven to rotate synchronously, so that the positions of the plurality of elastic clamping pieces 230 change. It should be noted that the rotating sleeve 260 in the embodiment is configured to drive the rotating sleeve 260 to rotate around the axis thereof when the clamping jaw sleeve 250 moves in the axial direction, thereby driving the clamping ring 240 and the plurality of elastic clamping pieces 230 to rotate synchronously.

[0034] More specifically, to achieve the clamping jaw sleeve 250 driving the rotating sleeve 260 to rotate around the axis thereof when the clamping jaw sleeve 250 moves in the axial direction, as shown in Figure 10 the outer periphery of the rotating sleeve 260 in the embodiment is uniformly provided with a plurality of first sliding rails 270 extending in the axial direction, a second sliding rail 280 is arranged between adjacent first sliding rails 270, the second sliding rail 280 is in a spiral shape, and the two ends of the second sliding rail 280 are respectively connected to the first end and the second end of adjacent first sliding rails 270. Three rails parallel to each other and extending in the axial direction of the rotating sleeve 260 are arranged in the first sliding rail 270. The two outer rails of the three rails are respectively connected to the second sliding rail 280, and the middle rail of the three rails is respectively connected to the first end and the second end of the two outer rails, as shown in Figure 12 the inner periphery of the clamping jaw sleeve 250 in the embodiment is fixedly provided with a plurality of elastic protrusions 251, the elastic protrusions 251 can slide through the first sliding rail 270 and the second sliding rail 280, when the clamping jaw sleeve 250 moves in the axial direction, the clamping jaw sleeve 250 does not rotate in the peripheral direction, so that the elastic protrusions 251 in the clamping jaw sleeve 250 slide in the second sliding rail 280. Since the second sliding rail 280 is in a spiral shape and connects the first end and the second end of adjacent first rails 271, the elastic protrusions 251 and the second sliding rail 280 push the rotating sleeve 260 to rotate around the axis thereof.

[0035] as shown in Figure 10As shown, the depths of the three tracks inside the first slide rail 270 of the present invention are different, and the connection position between the middle track and the two side tracks is connected by a step surface (the step surface is stepped, and when the elastic protrusion 251 enters the lower end of the step surface, it is similar to moving to the next step, and thus cannot return to the previous position). The step surface has an inclined surface, which enables the elastic protrusion 251 to move from one track to another. The depths of the three tracks gradually increase in a preset direction, for example, Figure 10 As shown, the depths of the three rails gradually increase from left to right. The depth of the same second rail 280 is not the same everywhere, but gradually becomes shallower. For example, Figure 10 As shown, the depth of the second slide rail 280 gradually becomes shallower from left to right, so that the elastic protrusion 251 passes through the second slide rail 280 in the deepest track of the first slide rail 270 and enters the shallowest track of the other first slide rail 270.

[0036] For ease of description, Figure 10 The three tracks from left to right are named as the first track 271, the second track 272 and the third track 273, respectively. The elastic protrusion 251 inside the clamping jaw 250 is initially located in the deepest track in the first slide rail 270, that is, in the third track 273. Figure 10 As shown, when the clamping jaws 250 are Figure 10When the rotating sleeve 260 is moved in the arrow direction, the elastic protrusions 251 inside the clamping sleeve 250 are moved from the third track 273 inside the first slide rail 270 to the second slide rail 280, so that the rotating sleeve 260 rotates around its axis, and when the elastic protrusions 251 move to the end of the other first slide rail 270, the clamping sleeve 250 has been clamped in the clamping groove 140, and when the operator releases his hand, the elastic protrusions 251 inside the clamping sleeve 250 slide into the connecting position of the first track 271 and the second track 272, and pass over the step surface at the connecting position of the first track 271 and the second track 272, at this time, the rotating sleeve 260 does not rotate, and when it is necessary to disassemble the butter head 200, the operator needs to push the clamping sleeve 250 so that the clamping sleeve 250 is separated from the clamping groove 140, at this time, the elastic protrusions 251 inside the clamping sleeve 250 enter the second track 272 under the action of the inclined surface of the step surface, and slide along the second track 272 to the connecting position of the second track 272 and the third track 273, and the elastic protrusions 251 pass over the step surface at the connecting position of the second track 272 and the third track 273, when the clamping sleeve 250 is separated from the clamping groove 140, the operator releases the pushing of the clamping sleeve 250, so that the clamping sleeve 250 resets to drive the elastic protrusions 251 inside the inner circumference to move in the third track 273 and to the connecting position of the third track 273 and the second slide rail 280. When the butter head 200 is connected again, the rotating sleeve 260 still rotates clockwise, and the specific process is the same as described above, and will not be described in detail.

[0037] In a further embodiment, the clamping sleeve 250 of the present application is provided with an adjusting assembly, which can adjust the distance between the clamping ring 240 and the hinge joint 130 in the initial position, and when the distance between the clamping ring 240 and the hinge joint 130 is closer, the position of the clamping ring 240 is closer to the end of the plurality of elastic clamping pieces 230 having an arc, so that the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 is increased. It should be noted that the elastic clamping pieces 230 in the present embodiment are arranged as shown in Figure 5 and Figure 11 The end of the plurality of elastic clamping pieces 230 having an arc is suspended, and there is a gap between adjacent elastic clamping pieces 230, which provides space for the deformation of the elastic clamping pieces 230, and when the clamping ring 240 slides on the plurality of elastic clamping pieces 230, the length of the force arm of the elastic clamping pieces 230 when clamping the hinge joint 130 can be changed, as shown in Figure 5As shown, when the clamping ring 240 moves to the left, the length of the force arm of the plurality of elastic clamping pieces 230 clamping the articulated joint 130 is shortened, the difficulty of deformation of the plurality of elastic clamping pieces 230 is increased, so that the clamping force of the plurality of elastic clamping pieces 230 on the articulated joint 130 is increased, when the clamping ring 240 moves to the right, the length of the force arm of the plurality of elastic clamping pieces 230 clamping the articulated joint 130 is increased, the difficulty of deformation of the plurality of elastic clamping pieces 230 is reduced, so that the clamping force of the plurality of elastic clamping pieces 230 on the articulated joint 130 is reduced.

[0038] It should be noted that the grouting nail 120 and the tallow head 200 in the present application are installed and disassembled multiple times, which can cause fatigue deformation of the plurality of elastic clamping pieces 230 in the tallow head 200 near the position with the arc end, thereby affecting the clamping force of the plurality of elastic clamping pieces 230 on the articulated joint 130, therefore, the adjusting assembly in the present embodiment can adjust the position of the clamping ring 240 to reduce the influence of fatigue deformation.

[0039] Specifically, the adjusting assembly in the present embodiment includes a sliding block 300, an adjusting rod 310 and a limiting block 330, as shown in the figure. Figure 12 As shown, the sliding block 300 is circumferentially slidably arranged in the inner circumference of the clamping jaw sleeve 250, for easy connection, a rotating ring groove 252 is arranged in the inner circumference of the clamping jaw sleeve 250, the sliding block 300 is arranged in the rotating ring groove 252, the sliding block 300 can move along the rotating ring groove 252, the adjusting rod 310 axially slides through the sliding block 300, a rectangular through groove is formed in the sliding block 300, the cross section of the adjusting rod 310 is rectangular, one end of the adjusting rod 310 is fixedly connected to the clamping ring 240, when the adjusting rod 310 moves relative to the sliding block 300, the distance between the clamping ring 240 and the articulated joint 130 at the initial position can be adjusted.

[0040] It should be noted that when the operator connects the tallow head 200 and the grouting nail 120 together, the articulated joint 130 of the grouting nail 120 pushes the clamping jaw sleeve 250, the rotating ring groove 252 in the clamping jaw sleeve 250 drives the sliding block 300 to move synchronously, thereby the sliding block 300 drives the adjusting rod 310 to move axially, the adjusting rod 310 drives the clamping ring 240 to move away from the articulated joint 130, at this time, the difficulty of deformation of the plurality of elastic clamping pieces 230 is reduced, thereby facilitating the articulated joint 130 to enter the inside of the end with the arc of the plurality of elastic clamping pieces 230, when the plurality of elastic clamping pieces 230 clamps the articulated joint 130, the clamping jaw sleeve 250 resets, the clamping jaw sleeve 250 drives the rotating ring groove 252 to reset, thereby the rotating ring groove 252 drives the sliding block 300 and the adjusting rod 310 to move synchronously, the adjusting rod 310 pulls the clamping ring 240 to return to the initial position, thereby restoring the difficulty of deformation of the plurality of elastic clamping pieces 230.

[0041] When the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 needs to be adjusted, the operator can adjust the position of the adjusting rod 310 inside the sliding block 300 by adjusting the limiting block 330, thereby adjusting the position of the clamping ring 240 from the initial position to the position of the hinge joint 130. For example, when the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 needs to be increased, the limiting block 330 is first loosened, and then the adjusting rod 310 is pulled to move so that the elastic clamping piece 230 is closer to the hinge joint 130; when the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 needs to be reduced, the limiting block 330 is first loosened, and then the adjusting rod 310 is pushed to move so that the elastic clamping piece 230 is farther away from the hinge joint 130.

[0042] Specifically, the limiting block 330 in the embodiment is hinged at one end on the sliding block 300 and abuts at the other end on the adjusting rod 310. The adjusting rod 310 is provided with a plurality of limiting teeth 320, and the limiting block 330 is also provided with limiting teeth 320. A torsional spring (not shown in the figure) is arranged at the hinged position. The torsional spring tightly abuts the plurality of limiting blocks 330 on the adjusting rod 310, so that the limiting teeth 320 on the limiting block 330 and the limiting teeth 320 on the adjusting rod 310 are engaged, thereby limiting the adjusting rod 310 inside the sliding block 300. When adjustment is needed, the operator rotates the limiting block 330 around the hinged position against the action force of the torsional spring, so that the limiting teeth 320 of the limiting block 330 and the limiting teeth 320 of the adjusting rod 310 are disengaged, thereby adjusting the position of the adjusting rod 310 inside the sliding block 300.

[0043] It can be understood that as the number of disassembly of the butter head 200 increases, the end of the plurality of elastic clamping pieces 230 with an arc will be normally worn, thereby reducing the service life of the elastic clamping piece 230. Therefore, the elastic clamping piece 230 has an arc at both ends. When one end is worn to a greater extent, the two ends of the elastic clamping piece 230 can be exchanged, so that the unworn end is used, thereby prolonging the service life of the elastic clamping piece 230.

[0044] Specifically, in order to facilitate the elastic clamping piece 230 with an arc at both ends to be installed on the outer periphery of the ventilation sleeve 220, the present application coaxially and slidably provides a connecting sleeve 290 on the outer periphery of the ventilation sleeve 220. The outer periphery of the connecting sleeve 290 also has an arc, thereby being able to adapt to the plurality of elastic clamping pieces 230, so that the inner side of the plurality of elastic clamping pieces 230 is fitted on the outer periphery of the connecting sleeve 290.

[0045] In a further embodiment, the housing 210 in the embodiment of the present application is provided with a first elastic member 410, one end of the first elastic member 410 is connected to the inner wall of the housing 210, the other end of the first elastic member 410 is connected to one end of the vent sleeve 220, and a gasket 430 is arranged at both ends of the first elastic member 410, the arrangement of the gasket 430 can reduce the wear of the first elastic member 410 to the inside of the housing 210 and the vent sleeve 220, and at the same time, the gasket 430 has a through hole, which allows the slurry to flow.

[0046] More specifically, the second elastic member 420 is arranged between the housing 210 and the jaw sleeve 250 in the embodiment, one end of the second elastic member 420 is connected to the housing 210, the other end of the second elastic member 420 is connected to the jaw sleeve 250, at the same time, a plurality of guide rods 253 are arranged on the end of the jaw sleeve 250 close to the housing 210, and a guide hole 211 extending along the axial direction is arranged on the side wall of the jaw sleeve 250, the guide rod 253 is slidingly inserted into the guide hole 211, so that the jaw sleeve 250 can elastically slide axially on the housing 210.

[0047] It should be noted that the first elastic member 410 and the second elastic member 420 in the embodiment are both compression springs, and a limiting sleeve 400 is threadedly connected to the end of the housing 210 connecting the jaw sleeve 250, a limiting groove 401 is arranged on the inner periphery of the limiting sleeve 400, and a limiting ring 254 is arranged on the outer periphery of the jaw sleeve 250, the limiting ring 254 can axially slide in the limiting groove 401, so as to avoid the jaw sleeve 250 from being separated from the housing 210.

[0048] The specific working process of the basement waterproof construction device provided by the present application is described in combination with the above embodiment: Install the grouting nail 120 and the butter head 200: The operator installs the grouting nail 120 on the wall that needs waterproofing construction. The grouting nail 120 is perpendicular to the wall, and then the grouting pipe 110 of the grouting machine body 100 is connected to the grouting nail 120, so that the slurry inside the grouting machine body 100 enters the wall through the grouting pipe 110 and the grouting nail 120. A butter head 200 is connected to the grouting pipe 110, and a clamping claw sleeve 250 is axially elastically slidably provided on the shell 210 of the butter head 200. The operator holds the butter head 200 and pushes the butter head 200 to move toward the grouting nail 120. The clamping claw sleeve 250 will first abut against the hinged joint 130 of the grouting nail 120, and then when the operator applies force, the hinged joint 130 of the grouting nail 120 gradually moves in. The clamping ring 240 is inserted into the clamping jaw sleeve 250, and the clamping jaw sleeve 250 will squeeze the second elastic member 420. When the clamping jaw sleeve 250 moves, it drives the adjusting rod 310 to move through the sliding block 300 and the limit block 330. The adjusting rod 310 drives the clamping ring 240 to move, and the clamping ring 240 moves in the direction away from the hinge head 130. At the same time, since the clamping jaw sleeve 250 has the function of clamping the hinge head 130 after deformation, the clamping jaw sleeve 250 will not rotate during axial movement. The elastic protrusion 251 on the inner periphery of the clamping jaw sleeve 250 will slide in the second slide rail 280 of the rotating sleeve 260, thereby driving the clamping ring 240 to rotate. The clamping ring 240 drives multiple elastic clips 230 to rotate synchronously, thereby causing the positions of multiple elastic clamping rings 240 to change.

[0049] When the hinge head 130 gradually moves to contact with the multiple elastic clips 230, it gradually enters the inner side of the curved end of the multiple elastic clips 230. When the hinge head 130 is clamped by the multiple elastic clips 230, the clamping claw sleeve 250 also gradually resets and is clamped in the clamping groove 140. At this time, when the clamping claw sleeve 250 resets, it can drive the clamping ring 240 to reset synchronously, so that the clamping ring 240 is close to the hinge head 130, thereby ensuring that the multiple elastic clips 230 can tightly clamp the hinge head 130.

[0050] As the butter head 200 is used for a longer time, the multiple elastic clips 230 inside it will produce fatigue deformation near the position with the curved end due to repeated installation and disassembly, resulting in a decrease in the clamping force of the multiple elastic clips 230. Therefore, the limit block 330 can be moved to release the restriction of the limit block 330 on the adjustment rod 310. The operator pulls the adjustment rod 310 to change the position of the clamp ring 240 on the multiple elastic clips 230, so that the clamp ring 240 is closer to the hinge head 130 so that it can cover the fatigue-deformed part, thereby enhancing the clamping force of the multiple elastic clips 230 and preventing the hinge head 130 from detaching.

[0051] If one end of the plurality of elastic clips 230 is worn to a greater extent, the positions of the two ends of the plurality of elastic clips 230 may be swapped, thereby extending the service life of the elastic clips 230 .

[0052] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered to be within the scope of the present disclosure.

[0053] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
