Description

Technical Field

[0001] This application relates to the field of sample detection technology, and more specifically, to a sample processing device. Background Technology

[0002] Common sputum processing methods often fall short of achieving sample homogenization and liquefaction. Further optimization of sample pretreatment methods is needed to fully liquefy sputum samples and shorten liquefaction time. Sample processing devices are used to pre-treat medical samples before testing to achieve sample liquefaction and homogenization. Homogenization is achieved by rapidly rotating the sample processing vessel containing abrasive materials such as steel balls. However, existing sample processing devices have inadequate protection for their core components under abnormal operating conditions, making them prone to damage. Utility Model Content

[0003] The purpose of this application is to provide a sample processing apparatus to address at least one of the technical problems involved in the background art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] This application provides a sample processing device, including a housing module, a turntable module and an ultrasonic module uniformly mounted on the housing module. The ultrasonic module is located below the turntable module. A positioning groove is formed on the turntable module, and a probe through hole is formed at the bottom of the positioning groove. The ultrasonic module includes a probe driving assembly and an ultrasonic probe mounted on the probe driving assembly. The probe driving assembly is used to drive the ultrasonic probe to move in the vertical direction. The probe through hole is used for the ultrasonic probe to extend into. A limiting hole is also formed on the turntable module. The ultrasonic module also includes an anti-collision rod mounted on the probe driving assembly. The anti-collision rod is used to move synchronously and in the same direction as the ultrasonic probe, and the anti-collision rod is used to cooperate with the limiting hole.

[0006] Optionally, the ultrasonic probe includes a probe body and a contact end fixed to the probe body. The contact end is used to extend into the probe through-hole so that the distance between the anti-collision rod and the inner wall of the limiting hole is less than the distance between the contact end and the inner wall of the probe through-hole.

[0007] The beneficial effect of this technical solution is that, in the event of a malfunction or abnormal operation, the turntable will strike the anti-collision bar instead of the contact end, thereby protecting the ultrasonic probe.

[0008] Optionally, the turntable module includes a turntable, and both the limiting hole and the positioning groove are formed on the turntable, with the limiting hole located inside the positioning groove in the axial direction of the turntable.

[0009] The beneficial effects of this technical solution are as follows: by setting the limiting hole inside the positioning groove, the part between the positioning groove and the center of the turntable is effectively utilized, making the turntable module more compact and reducing the volume occupied by the turntable module, thereby improving the compactness of the sample processing device and reducing the volume occupied by the sample processing device.

[0010] Optionally, the ultrasonic module further includes an annular water receiving tray, which is fitted onto the ultrasonic probe, and the water receiving tray and the ultrasonic probe are sealed together.

[0011] The beneficial effects of this technical solution are as follows: In some cases, leakage of the sample processing vessel may occur. If the liquid flows into the equipment, it may easily cause damage or contamination of the components. This application provides a water receiving tray outside the ultrasonic probe. When the sample processing vessel leaks, the liquid will flow down from the probe through hole into the water receiving tray. Since the water receiving tray and the ultrasonic probe are sealed together, the liquid cannot continue to flow downwards, thereby making it difficult for the internal components of the equipment to come into contact with the leaked liquid, thus protecting the internal components of the equipment.

[0012] Optionally, the sample processing device provided in this application further includes a lid locking module, which includes a button and a limiting slider. The housing module includes a housing and a lid. One end of the lid is hinged to the housing, and the other end of the lid forms a snap-fit ​​end. The button passes through the side wall of the housing in a first direction. The limiting slider is located on the side of the button facing the inside of the housing. The limiting slider abuts against the button. The limiting slider slides against the side wall of the housing in the first direction. A limiting groove with an upward opening is formed on the limiting slider. A latch is formed on the inner wall of the limiting groove, which faces the button. The snap-fit ​​end is used to engage with the latch. The first direction is perpendicular to the side wall of the housing.

[0013] The beneficial effects of this technical solution are as follows: When the lid is fastened onto the box body, the locking end extends into the limiting groove, causing the locking end to engage with the latch, preventing the lid from moving upwards and completing the lid fastening action. When it is necessary to open the lid, pressing the button pushes the limiting slider to move into the box body in the first direction, causing the latch to disengage from the locking end, thereby allowing the lid to be opened. Compared with the existing technology that requires electronic control to unlock the lid, this application can open the lid only in non-powered mode, reducing dependence on electricity and providing convenience for use.

[0014] Optionally, the lid locking module further includes a positioning pin and a second return spring fitted onto the positioning pin. A vertically extending groove is formed on the side wall of the box body. The positioning pin and the second return spring are both disposed in the groove. A pin hole is provided at the bottom of the limiting groove. The snap-fit ​​end is used to engage with the snap-fit ​​to make pressure contact with the top of the positioning pin.

[0015] The beneficial effects of this technical solution are as follows: When the locking end engages with the bayonet, the positioning pin presses the locking end vertically under the elastic force of the second return spring, thereby improving the tightness of the engagement between the locking end and the bayonet, making the fit between the locking end and the bayonet less prone to failure, and improving the reliability of locking. When it is necessary to open the box lid, pressing the button causes the limit slider to move towards the inside of the box, the locking end and the bayonet to separate, the second return spring restores its elastic deformation, and drives the positioning pin to move upward, thereby causing the positioning pin to drive the entire box lid to spring upward, making it easier for the staff to fully open the box lid.

[0016] Optionally, the lid locking module further includes a third return spring, the axis of which is parallel to the first direction. One end of the third return spring is fixed to the side wall of the box body in the first direction, and the other end of the third return spring is fixed to the limiting slider.

[0017] The beneficial effect of this technical solution is that when the staff presses the button, the button causes the limit slider to move in the first direction, which in turn causes the third return spring to deform elastically. When the staff no longer contacts the button, the button returns to its initial position under the elastic force of the third return spring.

[0018] Optionally, the lid locking module further includes a limit motor and a second cam. The limit motor is mounted on the box body, and the second cam is mounted on the output shaft of the limit motor. In the first direction, the second cam is located on the side of the limit slider away from the button, and the output shaft of the limit motor is set perpendicular to the first direction.

[0019] The beneficial effects of this technical solution are as follows: In this way, the limit motor can be controlled to rotate the second cam, so that the cam abuts against the limit slider, thereby preventing the staff from opening the box lid by pressing the button. When the sample processing device is in the sample processing state, this can improve the safety of the equipment operation. After the sample processing is completed, the limit motor can be controlled to rotate the second cam, so that the second cam separates from the limit slider, and the staff can open the box lid by pressing the button.

[0020] Optionally, the sample processing device provided in this application further includes a capping module, which includes a cap, a locking sleeve, a locking pin, and a locking block. The cap and the locking sleeve are coaxially arranged with the turntable. The locking sleeve is fixed to the turntable. The locking block has a socket hole, and the locking block is fitted onto the locking pin through the socket hole. A limiting protrusion is formed on the locking pin, and the limiting protrusion protrudes from the locking pin in the radial direction. A connecting hole is formed on the locking sleeve. The cap is used to be stacked on the turntable. A pin through hole is formed on the cap, which is coaxially arranged with the connecting hole. The locking pin is used to pass through the pin through hole and the connecting hole, so that the limiting protrusion abuts against the locking sleeve from bottom to top, and the locking block abuts against the cap from top to bottom.

[0021] The beneficial effects of this technical solution are as follows: After the sample processing container is placed in each positioning slot on the turntable, the pressure cap is stacked on top of the turntable, and the end of the positioning pin with the limit protrusion is inserted into the connecting hole through the pin hole. The locking block is rotated, which in turn causes the locking pin to rotate, so that the locking block presses the pressure cap, and the limit protrusion presses the locking sleeve, thereby achieving the purpose of fixing the pressure cap to the turntable and restricting the sample processing container between the pressure cap and the turntable.

[0022] Optionally, both the connecting hole and the pin through hole are coaxially arranged with the turntable. Two grooves are formed on the wall of the connecting hole, and the two grooves are symmetrically arranged on both sides of the connecting hole in the radial direction. Two limiting protrusions are formed on the locking pin, and the two limiting protrusions are symmetrically arranged on both sides of the locking pin in the radial direction. The two grooves are used to allow the two limiting protrusions and the locking pin to extend into the connecting hole together.

[0023] The beneficial effect of this technical solution is that, when the two limiting protrusions and the locking pin are inserted into the connecting hole together, rotating the locking pin causes the limiting protrusions to be located below the locking sleeve. At this time, the locking block presses against the cover, and the limiting protrusions press against the locking sleeve. In this embodiment, the part of the limiting protrusion that contacts the locking sleeve can be curved or triangular, which facilitates the limiting protrusions to gradually move below the locking sleeve under pressure.

[0024] The technical solution provided in this application can achieve at least one of the following beneficial effects:

[0025] In the sample processing device provided in this application, the anti-collision rod moves synchronously and in the same direction as the ultrasonic probe. When the ultrasonic probe contacts the sample processing container, the anti-collision rod extends into the limiting hole. When a malfunction or abnormal operation causes the turntable to rotate, the turntable is limited by the anti-collision rod located in the limiting hole, making it difficult for the turntable to rotate, thereby making it difficult for the turntable to cause serious damage to the ultrasonic probe.

[0026] The additional technical features and advantages of this application will become more apparent from the following description or from practical application. Attached Figure Description

[0056] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0058] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0059] An ultrasonic probe 13 is installed in the sample processing device. The bottom surface of the sample processing vessel 04 facilitates the contact between the ultrasonic probe 13 and the sample processing vessel 04. The ultrasonic probe 13 can also enhance the homogenization effect of the sample. However, when the ultrasonic probe 13 is in contact with the sample processing vessel 04, in the event of a malfunction or abnormal operation, the rotation of the turntable 05 may severely impact the ultrasonic probe 13, causing damage to the ultrasonic probe 13.

[0060] like Figures 1 to 8 As shown, this application provides a sample processing device, including a housing module, a turntable module and an ultrasonic module uniformly installed on the housing module. The ultrasonic module is located below the turntable module. A positioning groove is formed on the turntable module, and a probe through hole 14 is formed at the bottom of the positioning groove. The ultrasonic module includes a probe driving assembly and an ultrasonic probe 13 installed on the probe driving assembly. The probe driving assembly is used to drive the ultrasonic probe 13 to move in the vertical direction. The probe through hole 14 is used for the ultrasonic probe 13 to extend into. A limiting hole 21 is also formed on the turntable module. The ultrasonic module also includes an anti-collision rod 20 installed on the probe driving assembly. The anti-collision rod 20 is used to move synchronously and in the same direction as the ultrasonic probe 13. The anti-collision rod 20 is used to cooperate with the limiting hole 21.

[0061] In the sample processing device provided in this application, the anti-collision rod 20 moves synchronously and in the same direction as the ultrasonic probe 13. When the ultrasonic probe 13 contacts the sample processing container 04, the anti-collision rod 20 extends into the limiting hole 21. When a malfunction or abnormal operation causes the turntable 05 to rotate, the turntable 05 is limited by the anti-collision rod 20 located in the limiting hole 21, making it difficult for the turntable 05 to rotate, thereby making it difficult for the turntable 05 to cause serious damage to the ultrasonic probe 13.

[0062] As can be understood, in this embodiment of the application, the turntable module includes a turntable drive 09 installed on the housing module, which is used to drive the turntable 05 to rotate.

[0063] like Figure 5As shown, optionally, the ultrasonic probe 13 includes a probe body 19 and a contact end 17 fixed to the probe body 19. The contact end 17 is used to extend into the probe through-hole 14, so that the distance between the anti-collision rod 20 and the inner wall of the limiting hole 21 is less than the distance between the contact end 17 and the inner wall of the probe through-hole 14. In this way, in the event of a malfunction or abnormal operation, the turntable 05 will impact the anti-collision rod 20 instead of the contact end 17, thereby protecting the ultrasonic probe 13. Alternatively, the distance between the anti-collision rod 20 and the inner wall of the limiting hole 21 can be equal to the distance between the contact end 17 and the inner wall of the probe through-hole 14. In this embodiment, the limiting rod is used to fit against the inner wall of the limiting hole 21.

[0064] Optionally, the turntable module includes a turntable 05, and both the limiting hole 21 and the positioning groove are formed on the turntable 05. The limiting hole 21 is located inside the positioning groove in the axial direction of the turntable 05. It is understood that the position of the anti-collision rod 20 in the vertical direction should correspond to the position of the limiting hole 21, and the position of the probe through hole 14 should correspond to the position of the contact end 17. That is, the anti-collision rod 20 is located inside the ultrasonic probe 13 in the axial direction of the turntable 05. To achieve better homogenization and liquefaction of the sample, the sample should have an appropriate radius of rotation, and there should be an appropriate distance between the sample's position on the turntable 05 and the center of the turntable 05. Setting the limiting hole 21 inside the positioning groove effectively utilizes the portion between the positioning groove and the center of the turntable 05, making the turntable module more compact, reducing the volume occupied by the turntable module, thereby improving the compactness of the sample processing device and reducing the volume occupied by the sample processing device.

[0065] Optionally, the turntable 05 has a plurality of positioning grooves and a plurality of limiting holes 21, with each positioning groove corresponding to each limiting hole 21.

[0066] Optionally, the ultrasonic module further includes a ring-shaped water receiving tray 18, which is fitted onto the ultrasonic probe 13, and the water receiving tray 18 and the ultrasonic probe 13 are sealed together. In some cases, leakage may occur in the sample processing vessel 04. If the liquid flows into the equipment, it can easily cause damage or contamination to the components. In this application, a water receiving tray 18 is fitted over the ultrasonic probe 13. When the sample processing vessel 04 leaks, the liquid will flow down from the probe through-hole 14 into the water receiving tray 18. Since the water receiving tray 18 and the ultrasonic probe 13 are sealed together, the liquid cannot continue to flow downwards, thus making it difficult for the internal components of the equipment to come into contact with the leaked liquid, thereby protecting the internal components of the equipment. In this embodiment, the anti-collision bar 20 can be installed on the top edge of the water receiving tray 18, so that the anti-collision bar 20 utilizes the space occupied by the water receiving tray 18, further improving the compactness and volume of the ultrasonic module.

[0067] Preferably, the housing module includes an upper fixing plate 06, on which a first insertion hole and a second insertion hole are formed. The ultrasound module also includes a guide post 07, a connecting plate 10, and a probe holder 22. The probe drive assembly includes a probe drive motor 11, a first cam, and a first return spring 08. The turntable module is mounted on the upper fixing plate 06. The connecting plate 10 is vertically arranged, with its top end fixed to the upper fixing plate 06. The guide post 07 is vertically arranged, with its top end fixed to the upper fixing plate 06. The probe drive motor 11 is fixed to the connecting plate 10. The first cam 12 is fixed to the output shaft of the probe drive motor 11. The first return spring 08 is fitted onto the guide post 07, and the bottom end of the first return spring 08 is fixedly connected to the guide post 07. The probe seat 22 slides in the vertical direction with the guide post 07, and the bottom of the probe seat 22 abuts against the first return spring 08. The ultrasonic probe 13 is mounted on the probe seat 22. The first cam 12 and the top surface of the step position of the probe seat 22 make pressure contact in the vertical direction. The anti-collision rod 20 is used to pass through the first insertion hole, and the ultrasonic probe 13 is used to pass through the second insertion hole. In this way, when the probe drive motor 11 is started, it drives the first cam 12 to rotate. Under the action of the first cam 12 and the first return spring 08, the probe seat 22, the ultrasonic probe 13, the anti-collision rod 20, and the water receiving tray 18 can all reciprocate in the vertical direction.

[0068] like Figure 8As shown, optionally, the sample processing device provided in this application embodiment further includes a lid locking module. The lid locking module includes a button 28 and a limiting slider 32. The housing module includes a box body 02 and a lid 01. One end of the lid 01 is hinged to the box body 02, and the other end of the lid 01 forms a snap-fit ​​end 27. The button 28 passes through the side wall of the box body 02 in a first direction. The limiting slider 32 is located on the side of the button 28 facing the inside of the box body 02. The limiting slider 32 abuts against the button 28. The limiting slider 32 slides against the side wall of the box body 02 in the first direction. A limiting groove with an upward opening is formed on the limiting slider 32. A latch 39 is formed on the inner wall of the limiting groove. The latch 39 is positioned facing the button 28. The snap-fit ​​end 27 is used to engage with the latch 39. The first direction is perpendicular to the side wall of the box body 02. Understandably, the side with the latching end 27 is the front side of the cover 01, and the side hinged to the box body 02 is the rear side of the cover 01, with the first direction being the front-rear direction of the housing module. Thus, when the cover 01 is fastened onto the box body 02, the latching end 27 extends into the limiting groove, engaging with the latch 39, preventing the cover 01 from moving upwards, completing the cover 01 fastening action. When it is necessary to open the cover 01, the button 28 is pressed. The button 28 pushes the limiting slider 32 inwards into the box body 02 in the first direction, disengaging the latch 39 from the latching end 27, thereby allowing the cover 01 to open. Compared to the prior art where the cover 01 must be unlocked electronically, this application allows the cover 01 to be opened only in a non-powered mode, reducing reliance on electricity and providing convenience for use. Understandably, the latching end 27 engages with the latch 39 via a hook-like portion.

[0069] Optionally, the locking module of the lid 01 further includes a positioning pin 35 and a second return spring 34 fitted on the positioning pin 35. A vertically extending groove is formed on the side wall of the box body 02. The positioning pin 35 and the second return spring 34 are both disposed in the groove. A pin hole is provided at the bottom of the limiting groove. The snap-fit ​​end 27 is used to engage with the snap-fit ​​opening 39 to make pressure contact with the top end of the positioning pin 35. In this way, when the locking end 27 engages with the bayonet 39, the positioning pin 35 presses the locking end 27 vertically under the elastic force of the second return spring 34, thereby improving the tightness of the engagement between the locking end 27 and the bayonet 39, making the fit between the locking end 27 and the bayonet 39 less prone to failure, and improving the reliability of locking. When it is necessary to open the box cover 01, press the button 28 to move the limit slider 32 to the inside of the box body 02, the locking end 27 and the bayonet 39 separate, the second return spring 34 restores its elastic deformation, and drives the positioning pin 35 to move upward, thereby causing the positioning pin 35 to drive the box cover 01 to spring upward as a whole, thus making it easier for the staff to fully open the box cover 01.

[0070] Optionally, the lid 01 locking module further includes a third return spring 30. The axis of the third return spring 30 is parallel to the first direction. One end of the third return spring 30 is fixed to the side wall of the box body 02 in the first direction, and the other end is fixed to the limiting slider 32. Thus, when the operator presses the button 28, the button 28 moves the limiting slider 32 in the first direction, thereby causing the third return spring 30 to elastically deform. When the operator is no longer in contact with the button 28, the button 28 returns to its initial position under the elastic force of the third return spring 30. In this embodiment of the application, in order to prevent the button 28 and the limiting slider 32 from falling off the side wall of the box 02, preferably, the button 28 is fixedly connected to the limiting slider 32, and the cross-sectional area of ​​the limiting slider 32 perpendicular to the first direction is greater than the cross-sectional area of ​​the button 28 perpendicular to the first direction. Thus, when the end of the button 28 extends from inside the box 02 to outside the box 02, the side wall of the box 02 can restrict the limiting slider 32 inside the box 02.

[0071] Optionally, the lid 01 locking module further includes a limiting motor 31 and a second cam 33. The limiting motor 31 is mounted on the box body 02, and the second cam 33 is mounted on the output shaft of the limiting motor 31. In the first direction, the second cam 33 is located on the side of the limiting slider 32 away from the button 28, and the output shaft of the limiting motor 31 is perpendicular to the first direction. In this embodiment, the limiting motor 31 can be mounted on the box body 02 by a special bracket or fixed to a fixing plate. In this way, the limiting motor 31 can be controlled to rotate the second cam 33, so that the second cam 33 abuts against the limiting slider 32, thereby preventing the operator from opening the lid 01 by pressing the button 28. When the sample processing device is in the sample processing state, this can improve the safety of the equipment operation. After the sample processing is completed, the limiting motor 31 can be controlled to rotate the second cam 33, so that the second cam 33 separates from the limiting slider 32, and the operator can then open the lid 01 by pressing the button 28.

[0072] like Figure 6 and Figure 7As shown, optionally, the sample processing device provided in this application embodiment further includes a capping module. The capping module includes a cap 03, a locking sleeve 24, a locking pin 26, and a locking block 23. The cap 03 and the locking sleeve 24 are both coaxially arranged with the turntable 05. The locking sleeve 24 is fixed to the turntable 05. The locking block 23 has a socket hole, and the locking block 23 is fitted onto the locking pin 26 through the socket hole. A limit protrusion 25 is formed on the locking pin 26. The limiting protrusion 25 on the radial side of the locking pin 26 protrudes from the locking pin 26. A connecting hole 37 is formed on the locking sleeve 24. The pressure cover 03 is used to stack on the turntable 05. A pin through hole is formed on the pressure cover 03 and is coaxially arranged with the connecting hole 37. The locking pin 26 is used to pass through the pin through hole and the connecting hole 37 so that the limiting protrusion 25 abuts against the locking sleeve 24 from bottom to top, and the locking block 23 abuts against the pressure cover 03 from top to bottom. In this way, after the sample processing container 04 is placed in each positioning slot on the turntable 05, the pressure cap 03 is stacked on top of the turntable 05. The end of the positioning pin 35 with the limiting protrusion 25 is inserted into the connecting hole 37 through the pin hole. The locking block 23 is rotated, which in turn causes the locking pin 26 to rotate 90°, so that the locking block 23 presses the pressure cap 03 and the limiting protrusion 25 presses the locking sleeve 24, thereby achieving the purpose of fixing the pressure cap 03 to the turntable 05 and restricting the sample processing container 04 between the pressure cap 03 and the turntable 05. When it is necessary to separate the pressure cap 03 from the turntable 05, simply rotate the locking block 23 in the opposite direction to make the locking pin 26 rotate 90° in the opposite direction to remove the pressure cap 03 from the turntable 05. Compared with the prior art of threading the pressure cap 03 to the turntable 05, the convenience of operation is improved.

[0073] The sample processing canisters 04 may have certain processing tolerances, and the height of each sample processing canister 04 may differ. After each sample processing canister 04 is placed into its corresponding positioning slot, there may be gaps of varying sizes between the cap 03 and the top of each sample processing canister 04. During operation of the sample processing device, the sample processing canister 04 may shake. In this embodiment, the cap module further includes a silicone pad 38, which is fixed to the bottom surface of the cap 03. After the cap 03 is fixedly connected to the turntable 05, the silicone pad 38 is located between the cap 03 and the positioning slot. The silicone pad 38 makes pressure contact with the sample processing canister 04 in the positioning slot, thus pressing the sample processing canister 04 tightly into the positioning slot, making it less likely for the sample processing canister 04 to shake during operation of the sample processing device.

[0074] Optionally, both the connecting hole 37 and the pin through hole are coaxially arranged with the turntable 05. Two grooves 36 are formed on the wall of the connecting hole 37, and the two grooves 36 are symmetrically arranged on both sides of the connecting hole 37 in the radial direction. Two limiting protrusions 25 are formed on the locking pin 26, and the two limiting protrusions 25 are symmetrically arranged on both sides of the locking pin 26 in the radial direction. The two grooves 36 are used to allow the two limiting protrusions 25 and the locking pin 26 to extend into the connecting hole 37 together. In this way, when the two limiting protrusions 25 and the locking pin 26 extend into the connecting hole 37 together, the locking pin 26 is rotated so that the limiting protrusions 25 are located below the locking sleeve 24. At this time, the locking block 23 presses against the pressure cover 03, and the limiting protrusions 25 press against the locking sleeve 24. In this embodiment, the portion of the limiting protrusion 25 that contacts the locking sleeve 24 can be curved or triangular, facilitating the gradual movement of the limiting protrusion 25 under pressure below the locking sleeve 24. Preferably, in this embodiment, a locking and unlocking indicator 40 is provided at the corresponding position of the locking block 23 on the pressure cover 03. Of course, only one limiting protrusion 25 can be provided, or the two limiting protrusions 25 can be asymmetrically arranged.
