Description

Technical Field

[0001] The invention relates to the technical field of metal pouring, and in particular to a ladle auxiliary system for a pouring system. Background Art

[0002] In the metal casting process, a ladle is usually used to hold the molten metal and transfer it to the mold. The ladle generally includes a ladle body and a handle. The ladle body is provided with a ladle spout. When in use, the handle is held to pour the molten metal in the ladle along the ladle spout into the mold cavity. However, in the actual production process, the metal raw materials to be smelted contain some impurities that are difficult to remove. During the smelting process, these impurities will form slag and mix in the molten metal. If these slags enter the ladle and are poured into the mold cavity with the molten metal, defects such as pores and thermal cracks will occur in the cast parts, affecting product quality.

[0003] In the prior art, auxiliary structures are generally added to the ladle to prevent slag from entering the mold cavity, such as a non-ferrous metal mold gravity casting molten metal skimming ladle disclosed in the patent with the authorization announcement number CN205551453U. The non-ferrous metal mold gravity casting molten metal skimming ladle includes a ladle body and a ladle handle connected to the outer wall of the ladle body. The ladle body is provided with a spout, and a slag skimming plate is connected to the ladle body. The ladle is provided with a slag skimming plate to block the slag floating on the upper layer of the molten metal when pouring the molten metal, thereby preventing the slag from entering the mold cavity with the molten metal. However, the slag skimming plate provided in the ladle can only block the slag in the cavity on the side of the slag skimming plate facing away from the spout, but cannot block the slag in the cavity on the side of the slag skimming plate facing the spout, and cannot completely prevent the slag from being injected into the mold cavity.

[0004] In order to better prevent the slag from flowing out, in the prior art, the molten metal in the ladle is usually left to stand still first, so that the slag floats to the surface of the molten metal, and then a skimmer is used to manually remove most of the slag that floats to the surface, and then the molten metal is poured into the mold cavity. During the pouring process, a piece of slag-blocking cotton is placed at the ladle mouth to block the small residual slag in the ladle that has not been cleaned out, so as to prevent the fine slag from entering the mold cavity. Since the slag-blocking cotton is easy to float on the surface of the molten metal, one person is required to pour the molten metal, and one person uses a push rod to press the slag-blocking cotton to keep the slag-blocking cotton near the pouring nozzle to prevent the slag-blocking cotton from moving with the flow of the molten metal. The above-mentioned process of scooping the upper slag of the molten metal and pressing the slag-blocking cotton is manually operated, which requires a lot of manpower. At the same time, the temperature of the molten metal and slag is very high, and it is easy to splash when pouring, causing safety accidents. The molten metal and slag will also release harmful gases. Working near the molten metal for a long time will affect human health. Summary of the invention

[0005] The present invention provides a ladle auxiliary system for a pouring system to solve the technical problem that in the prior art, when removing the slag in the ladle, it is necessary to first manually use tools to manually scoop out the slag on the surface of the molten metal, and then manually press the slag blocking cotton on the ladle mouth. The whole process consumes a lot of manpower, the time for manual participation in the operation is long, and safety accidents are prone to occur.

[0006] In order to solve the above problems, the present invention provides a pouring system for a ladle auxiliary system adopting the following technical solutions: A pouring ladle auxiliary system for a pouring system, comprising: The ladle body and the U-shaped handle, the ladle body is barrel-shaped, a ladle spout is arranged on the front side of the top of the ladle body, and the U-shaped handle spans over the top of the ladle body from left to right and is connected to the outer side wall of the ladle body; Also includes: A bracket is connected to the outer side wall of the ladle body, and the top end of the bracket extends to the top of the ladle body; The rotating body is rotatably assembled on the top of the bracket, and the rotating body is provided with a first connecting hole and a second connecting hole arranged at intervals in the circumferential direction. The rotating body is connected with a connecting piece, and a slag-blocking cotton is provided at one end of the connecting piece facing away from the rotating body; A tension spring, one end of which is connected to the middle section of the bracket, and the other end of which is hooked in the first connecting hole or the second connecting hole on the rotating body to tighten and fix the rotating body on the bracket. When the tension spring is hooked in the first connecting hole, the slag-blocking cotton is located above the ladle body. When the tension spring is hooked in the second connecting hole, the slag-blocking cotton is located at the ladle mouth to filter the slag. The support member is detachably connected to the bracket and is located above the ladle body. A drive motor is installed on the support member, and a transmission assembly is connected to the output shaft end of the drive motor. Two groups of slag scooping components are located in the inner cavity of the ladle body. The slag scooping components include a first orifice plate and a second orifice plate. A slag scooping angle is formed between the first orifice plate and the second orifice plate. The opening directions of the slag scooping angles of the two groups of slag scooping components are opposite. The driving motor is connected to the two groups of slag scooping components through the transmission component to drive the opening sides of the slag scooping angles in the two groups of slag scooping components to reciprocate and rotate toward the molten metal to collect the slag within the slag scooping angle.

[0007] By adopting the above technical scheme, before pouring the molten metal in the ladle body into the mold cavity, the drive motor is started first, and the two groups of slag scooping components are driven to rotate back and forth through the transmission component. The two groups of slag scooping components rotate against the molten metal with the slag scooping angle opening for many times, and the slag on the surface of the molten metal is scooped for many times, so that the slag on the surface of the molten metal is collected between the first orifice plate and the second orifice plate. The two groups of slag scooping components can finally move to a state where the slag scooping angle opening is relative to each other, so that the scooped slag is clamped between the two groups of slag scooping components. After the slag is clamped by the two groups of slag scooping components, the support member together with the drive motor, transmission component and slag scooping component thereon is removed to clean the slag. In this process, the slag scooping link does not require manual participation. It only needs to manually remove the support member to remove the slag after the slag scooping component has scooped the slag. The operator has a shorter time in close contact with the molten metal and slag, which can reduce the probability of safety accidents and reduce injuries to the operator. At the same time, it can save manpower and improve the slag scooping efficiency.

[0008] Before pouring the molten metal in the ladle body, first adjust the angle of the rotating body so that the tension spring hook is hung in the second connecting hole. At this time, the slag-blocking cotton moves to the inner cavity of the ladle body and is blocked at the ladle mouth. The rotating body is fixed in position under the action of the tension spring, and the slag-blocking cotton is fixed at the ladle mouth. In the process of pouring the molten metal, there is no need to manually use a push rod to press the slag-blocking cotton, which can reduce manual participation, save manpower, and avoid long-term close contact between operators and high-temperature molten metal and slag to cause safety accidents and affect their health. After the molten metal is poured, the rotating body can be adjusted again so that the tension spring hook is hung in the first connecting hole. At this time, the slag-blocking cotton moves to the top of the ladle body, which does not affect the continued injection of new molten metal into the ladle body.

[0009] Furthermore, the transmission assembly includes a driving gear, two driven gears, and two sleeves; the driving gear is transmission-connected to the output shaft end of the driving motor, the two sleeves are rotatably assembled on the support, the two sleeves extend vertically and are arranged at intervals in the horizontal direction, the bottom ends of the two sleeves are respectively connected to the two groups of slag scooping assemblies, the two driven gears are respectively fixedly mounted on the two sleeves, the two driven gears are meshed with each other, and one of the driven gears is meshed with the driving gear.

[0010] By adopting the above technical solution, when the driving motor drives the driving gear to rotate, it drives the two driven gears to rotate in the opposite direction, thereby driving the two groups of slag scooping components to rotate in the opposite direction.

[0011] Furthermore, the two first orifice plates in the two groups of slag scooping assemblies are respectively fixedly connected to the bottom of the two sleeves, the first orifice plates are arranged in a vertical plane, the second orifice plates include a hinge shaft extending radially along the ladle body, the second orifice plates are hinged to the first orifice plates through the hinge shaft, and the support member is provided with a flipping assembly, which is transmission-connected to the hinge shafts in the two second orifice plates to drive the second orifice plates to flip back and forth through the hinge shaft, so that when the slag scooping angle opening in the slag scooping assembly rotates toward the molten metal, the second orifice plates are flipped to the slag scooping angle being a right angle, and when the slag scooping angle opening in the slag scooping assembly rotates away from the molten metal, the second orifice plates are flipped to the slag scooping angle being an acute angle.

[0012] By adopting the above technical solution, the second orifice plate can be flipped. In the process of the two groups of slag scooping components moving toward each other to scoop out slag, the second orifice plate is in a horizontal state, which facilitates the slag to enter between the first orifice plate and the second orifice plate. In the process of the two groups of slag scooping components moving their openings away from each other to their initial positions after scooping out the slag, the second orifice plate is flipped to an inclined state, so that an acute angle is formed between the first orifice plate and the second orifice plate, thereby preventing the slag from falling off from between the first orifice plate and the second orifice plate.

[0013] Furthermore, the flip assembly includes two movable shafts and two rotating sleeves, the two movable shafts are respectively slidably installed in the two sleeves in the up and down directions, and the movable shaft and the sleeve are locked; the two rotating sleeves are respectively rotatably mounted on the two sleeves, and the bottom surface of the rotating sleeve is in contact with the top surface of the driven gear on the corresponding sleeve; a V-shaped slide groove is provided on the top of the rotating sleeve, and a limit rod is vertically connected to the movable shaft, and the limit rod is mounted on the top surface of the rotating sleeve; the end of the hinge shaft is connected to an eccentric shaft whose axis is parallel to the axis of the hinge shaft, and a horizontal slide groove is provided at the bottom end of the movable shaft, and the eccentric shaft is adapted to be inserted in the horizontal slide groove; a baffle is connected to the outside of the rotating sleeve, and a stopper is respectively provided on both sides of the horizontal line connecting the centers of the two driven gears on the support member, and the stopper corresponds to the meshing area position of the two driven gears, and the stopper is used to push the baffle when the rotating sleeve rotates to a set position with the driven gear so that the limit rod can fall into or leave the V-shaped slide groove.

[0014] Furthermore, the stopper includes a vertical rod and a horizontal rod, the vertical rod is connected to the support member, the middle part of the horizontal rod is connected to the top end of the vertical rod, and the two ends of the horizontal rod are used to push the baffle.

[0015] Furthermore, the rotating body includes a handle, a rotating shaft and a rotating block. The rotating shaft extends in the left and right directions and is rotatably assembled on the bracket. One end of the rotating shaft is fixedly connected to the handle, and the other end is fixedly connected to the rotating block. The handle includes a first handle rod and a second handle rod arranged at intervals in the circumferential direction of the rotating shaft. The first connecting hole is opened on the first handle rod, and the second connecting hole is opened on the second handle rod. The connecting member is connected to the rotating block.

[0016] By adopting the above technical solution, it is convenient to adjust the angle of the rotating body by holding the handle.

[0017] Furthermore, the connecting member includes a first connecting rod and a second connecting rod, the first connecting rod extends in the left-right direction, one end of the first connecting rod is connected to the rotating block, and the other end is connected to the second connecting rod, the second connecting rod extends along the radial direction of the rotating shaft and is perpendicular to the first connecting rod, and the end of the second connecting rod facing away from the first connecting rod is hinged with a cross connecting plate, and the cross connecting plate is detachably connected with slag blocking cotton.

[0018] By adopting the above technical solution, the cross connecting plate is hinged to the second connecting rod, so that the angle of the slag stopper cotton connected to the cross connecting plate can be adjusted. In the process of flipping the ladle body to pour the molten metal, the slag stopper cotton can be kept attached to the surface of the molten metal, thereby improving the effect of filtering the slag. The slag stopper cotton can be detachably connected to the second connecting rod, which is convenient for replacing the slag stopper cotton when it is damaged.

[0019] Furthermore, the first connecting rod is slidably assembled on the rotating block, and a compression spring is pressed between the rotating block and the first connecting rod. The compression spring applies an elastic force toward the ladle body to the first connecting rod, so that when the tension spring is hooked on the second connecting hole, the first connecting rod and the second connecting rod drive the slag stop cotton to be pressed against the surface of the molten metal in the ladle body.

[0020] By adopting the above technical solution, the compression spring can press the slag-blocking cotton tightly against the surface of the molten metal.

[0021] The beneficial effects of the ladle auxiliary system for a casting system provided by the present invention are as follows: a driving motor drives two groups of slag scooping components to rotate in opposite directions to scoop out molten slag, and manual slag scooping is not required, thus reducing the links requiring manual participation in the slag scooping process. During the pouring of molten metal, slag blocking cotton is fixed to the mouth of the ladle body by structures such as brackets and connectors. There is no need for humans to stand near the ladle body and use tools to press the slag blocking cotton, which can save manpower and shorten the time that operators are in close contact with high-temperature molten metal and slag, thereby reducing the probability of safety accidents and reducing adverse effects on human health.

[0022] The slag scooping assembly can reciprocate to scoop up slag multiple times, and the scooped slag can be clamped between the two groups of slag scooping assemblies, so that the slag can be prevented from falling off from the slag scooping assembly when the slag scooping assembly is removed to clean the slag. When the slag scooping assembly moves back to the initial position after scooping up the slag once during the slag scooping process, the second orifice plate can be flipped upward to shield the slag within the slag scooping angle, so as to prevent the slag from falling off from between the first orifice plate and the second orifice plate during this process.

When the tension spring 8 is hooked in the second connecting hole, the slag stopper cotton 10 is located in the inner cavity of the ladle body 1 and is blocked on the metal liquid surface near the ladle nozzle 101.

[0035] like Figure 2 , Figure 3 As shown, the support member 6 is L-shaped, including a vertical plate 601 and a horizontal plate 602 that are vertically connected. The vertical plate 601 is inserted into the above-mentioned second slot and is connected to the second connecting block 5 by fixing bolts. The horizontal plate 602 extends radially along the ladle body 1, and one end of the horizontal plate 602 facing away from the vertical plate 601 extends to above the center position of the ladle body 1.

[0036] like Figure 1 As shown, the driving motor 7 is fixedly mounted on the horizontal plate 602 , and the driving motor 7 is located on a side of the horizontal plate 602 facing away from the vertical plate 601 .

[0037] like Figure 5 , Figure 6 As shown, the transmission assembly includes two sleeves 15, a driving gear 19 and two driven gears 20. A stop boss is provided on the top of the sleeve 15, and the two sleeves 15 extend in the up-down direction and are arranged at intervals in the length direction of the horizontal plate 602. The sleeve 15 is rotatably mounted on the horizontal plate 602, and the sleeve 15 is stopped up and down by the stop boss on the top of the sleeve 15 and the horizontal plate 602 to prevent the sleeve 15 from falling off the horizontal plate 602.

[0038] The driving gear 19 is drivingly connected to the output shaft end of the driving motor 7 so as to rotate under the drive of the driving motor 7 .

[0039] The two driven gears 20 are respectively mounted on the two sleeves 15, the driven gears 20 are located above the stop boss, and the driven gears 20 are fixed to the sleeves 15. The two driven gears 20 mesh with each other, and one of the driven gears 20 meshes with the driving gear 19. When the driving gear 19 rotates, the two driven gears 20 are driven to rotate in the opposite direction, and the two sleeves 15 are driven to rotate in the opposite direction.

[0040] like Figure 1 , Figure 5 As shown, there are two groups of slag scooping assemblies, which are located at the top of the inner cavity of the ladle body 1. The slag scooping assembly includes a first orifice plate 25 and a second orifice plate. The first orifice plate 25 is provided with a plurality of first sieve holes for the flow of molten metal, and the first sieve holes are not shown in the figure. The first orifice plate 25 is arranged in a vertical plane and extends along the radial direction of the ladle body 1. One end of the first orifice plate 25 is fixedly connected to the bottom of the sleeve 15, and the other end is connected to an arc-shaped fixing plate 26. The end of the first orifice plate 25 close to the sleeve 15 is connected to a mounting plate 27.

[0041] like Figure 5 , Figure 7 As shown, the second orifice plate includes a hinge shaft 28 extending radially along the ladle body 1 and a plurality of slag scooping rods 29 connected to the hinge shaft 28. The plurality of slag scooping rods 29 are arranged at equal intervals along the axial direction of the hinge shaft 28. The space between any two adjacent slag scooping rods 29 forms a second sieve hole on the second orifice plate. The two ends of the hinge shaft 28 are rotatably mounted on the above-mentioned mounting plate 27 and the arc-shaped fixing plate 26. A slag scooping angle is formed between the first orifice plate 25 and the second orifice plate. The slag scooping angles of the two groups of slag scooping components face opposite directions. Figure 7 As shown, an eccentric shaft 30 is connected to one end of the hinge shaft 28 close to the sleeve 15, and the axis of the eccentric shaft 30 is parallel to the axis of the hinge shaft 28. When the second orifice plate is in a horizontal position, the eccentric shaft 30 is located on the horizontal side of the axis of the hinge shaft 28, and on the side of the axis of the hinge shaft 28 that is away from the first orifice plate 25.

[0042] In the initial state, the first perforated plates 25 in the two groups of slag scooping assemblies are close to each other, and the slag scooping angle openings in the two groups of slag scooping assemblies are opposite to each other.

[0043] like Figure 6 As shown, the flip assembly includes two movable shafts 22, two rotating sleeves 21 and two stoppers. The two movable shafts 22 are respectively inserted into the two sleeves 15. Figure 8As shown, the top of the movable shaft 22 is vertically connected to the limit rod 23, and the bottom is provided with a horizontally arranged semicircular notch, which forms a horizontal slide groove 2201 at the bottom of the rotating shaft 13, and the vertical groove side wall of the horizontal slide groove 2201 forms a push wall. The above-mentioned eccentric shaft 30 is inserted into the horizontal slide groove 2201, and the eccentric shaft 30 is close to the push wall. The eccentric shaft 30 is located on the horizontal side of the axis of the corresponding rotating shaft 13 and on the side away from the other rotating shaft 13. The eccentric shaft 30 can push the push wall while rotating with the sleeve 15, so that the movable shaft 22 rotates synchronously with the sleeve 15, and the rotation-stopping connection between the movable shaft 22 and the sleeve 15 is realized.

[0044] like Fig. 9 As shown, a V-shaped groove 2101 is provided on the top of the rotating sleeve 21, and a baffle 24 is connected to the outer wall of the rotating sleeve 21. When the movable shaft 22 is inserted into the sleeve 15, the limit rod 23 is mounted on the top surface of the rotating sleeve 21, and the limit rod 23 can fall into or leave the V-shaped groove 2101 during the rotation of the movable shaft 22. When the limit rod 23 falls into the V-shaped groove 2101, the movable shaft 22 is in a low position, and the second orifice plate is in a horizontal state. During the upward movement of the limit rod 23 from the V-shaped groove 2101, the movable shaft 22 gradually moves upward, and drives the eccentric shaft 30 to rotate around the hinge shaft 28 through the horizontal groove 2201 at the bottom, thereby driving the second orifice plate to rotate to an inclined state, so that an acute angle is formed between the second orifice plate and the first orifice plate 25. The two rotating sleeves 21 are respectively rotatably mounted on the two sleeves 15, and the rotating sleeves 21 and the sleeves 15 are tightly matched, so that the rotating sleeves 21 can rotate with the sleeves 15 when not subject to other external forces, and can rotate relative to the sleeves 15 when blocked by external forces. The rotating sleeves 21 are located above the driven gear 20, and the bottom surface of the rotating sleeves 21 is in contact with the top surface of the driven gear 20.

[0045] like Figure 6 As shown, the two stoppers are arranged on both sides of the horizontal line connecting the centers of the two driven gears 20, and the stoppers correspond to the meshing areas of the two driven gears 20. The stoppers include a vertical rod 32 and a horizontal rod 31, the vertical rod 32 is vertically connected to the horizontal plate 602, the horizontal rod 31 is vertically connected to the top of the vertical rod 32, and the middle of the horizontal rod 31 is connected to the vertical rod 32.

[0046] When the present invention is used, molten metal is first injected into the ladle body 1, and the molten metal is allowed to stand in the ladle body 1 for a period of time, and then the slag floats to the surface of the molten metal. At this time, the drive motor 7 is started, and the drive motor 7 drives the two sleeves 15 to rotate in the opposite direction, thereby driving the two groups of slag scooping components to rotate in the opposite direction, and the opening side of the slag scooping angle in the slag scooping component rotates toward the molten metal, and the slag in the molten metal is scooped into the slag scooping angle. The two groups of slag scooping components approach each other, and finally the slag is clamped between the two groups of slag scooping components. In this process, the rotating sleeve 21 rotates synchronously with the sleeve 15, the limit rod 23 is always located in the V-shaped slide groove 2101, and the second orifice plate is always in a horizontal state, so that the slag is conveniently scooped into between the first orifice plate 25 and the second orifice plate.

[0047] When the two groups of slag scooping components rotate until the openings face each other and are close to each other, the rotating sleeve 21 rotates with the sleeve 15 until the baffle 24 contacts the horizontal rod 31 in the stopper on one side, and the baffle 24 is blocked by the horizontal rod 31, and the rotating sleeve 21 cannot continue to rotate synchronously with the sleeve 15, so that the limiting rod 23 moves upward along the slope of the V-shaped slide 2101 to the horizontal top surface of the rotating sleeve 21, and the movable shaft 22 moves upward relative to the sleeve 15, and the movable shaft 22 drives the eccentric shaft 30 to swing upward around the hinge shaft 28, so that the second orifice plate flips to an inclined state. After that, the driving motor 7 reverses and drives the two groups of slag scooping components to rotate in the opposite direction, so that the two groups of slag scooping components are reset. During the reset process, the baffle 24 does not contact the stopper, so the rotating sleeve 21 can rotate synchronously with the sleeve 15, and the limiting rod 23 is always located on the horizontal top surface of the rotating sleeve 21. The second orifice plate is always in an inclined state to support and shield the slag, which can prevent the slag in the slag scooping angle from falling off during the reset process of the slag scooping component.

[0048] When the two groups of slag scooping components are about to be reset to the initial state, the rotating sleeve 21 rotates with the sleeve 15 until the baffle 24 contacts the horizontal rod 31 in the stopper on the other side, and the horizontal rod 31 on the other side pushes the baffle 24, driving the rotating sleeve 21 to rotate relative to the sleeve 15. When the slag scooping components are reset to the initial state, the limit rod 23 falls from the horizontal top surface of the rotating sleeve 21 into the V-shaped slide groove 2101, the movable shaft 22 moves downward relative to the sleeve 15, and the second orifice plate returns to the horizontal position. Then repeat the above steps, so that the two groups of slag scooping components salvage the slag in the ladle body 1 for many times, and finally turn off the drive motor 7 when the two groups of slag scooping components approach each other to clamp the slag. At this time, the support member 6 and the components thereon can be removed from the bracket 4, and the two groups of slag scooping components clamp the slag and leave the ladle body 1, completing the slag scooping process.

[0049] Before pouring the molten metal into the mold cavity, turn the handle 9 to adjust the position of the slag stopper 10, turn the handle 9 to the second handle rod 902 downward, and hook the tension spring 8 into the second connecting hole on the second handle rod 902. At this time, the slag stopper 10 extends into the ladle body 1, and is blocked at the ladle spout 101 and abuts against the molten metal surface. Then pour the molten metal into the mold cavity. During the pouring process, the slag stopper 10 always abuts against the molten metal surface near the ladle spout 101, blocking the slag in the molten metal and preventing the fine slag remaining in the molten metal from flowing into the mold cavity. After the molten metal in the ladle body 1 is poured out, turn the handle 9 again to make the first handle rod 901 face downward, and hook the tension spring 8 into the first connecting hole on the first handle rod 901. At this time, the slag stopper cotton 10 moves to the top of the ladle body 1, which does not affect the subsequent injection of new molten metal into the ladle body 1. If the slag stopper cotton 10 is damaged, it can be removed from the cross connecting plate for replacement.

[0050] The present invention provides a slag scooping assembly to scoop up the molten slag, which has a higher slag scooping efficiency and less manual participation in the slag scooping process, thereby reducing the adverse effects of the slag scooping process on human health. In addition, the present invention provides a support 4, a connector 12 and other structures to fix the slag stopper 10 near the ladle spout 101 during the pouring of the molten metal, without manually using tools to press the slag stopper 10, thereby saving manpower and improving the pouring efficiency.

[0051] In this embodiment, a flipping assembly is provided so that the second orifice plate of the slag scooping assembly can rotate up and down during the slag scooping process. The second orifice plate flips to an inclined state during the resetting process of the slag scooping assembly, so that an acute angle is formed between the first orifice plate 25 and the second orifice plate to prevent the scooped slag from falling. In other embodiments, the flipping assembly may not be provided. At this time, a fixed right angle is formed between the first orifice plate 25 and the second orifice plate. The two groups of slag scooping assemblies are controlled by the driving motor 7 to perform repeated slag scooping movements. At this time, slag will fall during the resetting process of the slag scooping assembly, but most of the slag on the top of the molten metal can still be scooped out.

[0052] In this embodiment, the eccentric shaft 30 pushes the push wall to drive the movable shaft 22 and the sleeve 15 to rotate synchronously, thereby realizing a non-rotating connection between the movable shaft 22 and the sleeve 15. In other embodiments, a limiting groove is provided on the inner wall of the sleeve 15, and a limiting protrusion is provided on the outer wall of the movable shaft 22. The limiting protrusion is adapted to be inserted in the limiting groove, so that the movable shaft 22 and the sleeve 15 are relatively non-rotating.
