Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a suction tip box, suction tip storage structure and medical equipment. Background Technology

[0002] Medical devices are commonly used to automate experiments, involving sample dispensing. Disposable pipette tips are used in this process. These tips typically come in different sizes to accommodate varying liquid volumes. During dispensing, the appropriate tip size must be placed on the dispensing platform so that the automated dispensing mechanism can retrieve it for aspiration and dispensing. Compared to permanent dispensing needles, disposable tips primarily prevent cross-contamination and ensure safe use.

[0003] Currently, nozzle boxes are commonly used to store nozzles. The size of the nozzles is manually identified, and different sizes are placed in separate nozzle boxes. These boxes are then positioned in designated locations to distinguish the nozzle sizes. However, in the use of existing nozzle boxes, it becomes difficult to automatically identify the nozzle sizes in each box using external detection devices when multiple nozzle boxes containing different sizes are mixed together. Utility Model Content

[0004] The main purpose of this utility model is to propose a suction tip box, suction tip storage structure and medical device, which aims to ensure the realization of automated identification of suction tip specifications.

[0005] To achieve the above objectives, the suction head box proposed in this utility model includes:

[0006] The support plate has multiple spaced-apart placement holes for placing suction heads; and

[0007] A support frame is provided at the bottom of the support plate and around the periphery of the support plate, and the side wall of the support frame is provided with a detection port;

[0008] When different sizes of suction heads are placed in the placement hole, the length exposed at the detection port varies.

[0009] In one embodiment, the detection port is provided on at least two side walls of the support frame.

[0010] In one embodiment, the support frame includes:

[0011] A first frame is disposed at the bottom of the support plate and surrounding the periphery of the support plate; and

[0012] The second frame is disposed on the side of the first frame away from the support plate and around the outer periphery of the first frame, and the inner diameter of the second frame is larger than the outer diameter of the first frame.

[0013] In one embodiment, the outer wall of the first frame is provided with a groove, and the inner wall of the second frame is provided with a protrusion. The protrusion of the second frame of one suction head box can be movably inserted into the groove of the first frame of the other suction head box.

[0014] In one embodiment, the two opposite sidewalls of the first frame are provided with gripping notches for an external robotic arm to insert and hold the suction head box.

[0015] This utility model also proposes a suction head storage structure, including a carrier and a suction head box as described in any of the above embodiments, wherein the carrier has a placement position and the suction head box can be detachably placed in the placement position.

[0016] In one embodiment, the suction head storage structure further includes:

[0017] A locking member is movably disposed on the carrier and located at opposite ends of the placement position. A limiting protrusion is provided on the outer periphery of the support frame of the suction head box on the side away from the carrier plate. The locking member is used to press against the limiting protrusion to restrict the suction head box to the placement position.

[0018] In one embodiment, the locking element includes:

[0019] A guide block is provided on the carrier and has a guide channel, the guide channel facing the placement position;

[0020] An elastic element is disposed within the guide channel, with one end of the elastic element away from the placement position connected to the guide block; and

[0021] The pressing block has one end slidably disposed in the guide channel and connected to the other end of the elastic member, while the other end of the pressing block is exposed in the guide channel.

[0022] In one embodiment, the end of the pressing block away from the guide channel has a first inclined surface and a second inclined surface, the first inclined surface being located on the side of the pressing block away from the placement position, and the second inclined surface being located on the side of the pressing block facing the placement position.

[0023] This utility model also proposes a medical device, including a suction tip storage structure as described in any of the above embodiments.

[0024] The technical solution of this utility model involves setting a carrier plate and a support frame in the tip box. The carrier plate has multiple spaced placement holes for placing the tips. The support frame is located at the bottom of the carrier plate and surrounds its perimeter. The side wall of the support frame has a detection port. Different sizes of tips, when placed in the placement holes, will have different lengths protruding from the detection port. Compared to existing tip boxes, this utility model's technical solution provides a detection port on the side wall of the support frame. This ensures that the tails of tips of different sizes are confined to the placement holes, and all tip tails are located on the same plane, resulting in different lengths of tip heads protruding from the detection port. By using an external detection element, the tip size can be determined based on the length of the tip protruding from the detection port, ensuring automated tip size identification.

[0044] Medical devices are commonly used to automate experiments, involving sample dispensing. Disposable pipette tips are used in this process. These tips typically come in different sizes to accommodate varying liquid volumes. During dispensing, the appropriate tip size must be placed on the dispensing platform so that the automated dispensing mechanism can retrieve it for aspiration and dispensing. Compared to permanent dispensing needles, disposable tips primarily prevent cross-contamination and ensure safe use.

[0045] Currently, nozzle boxes are commonly used to store nozzles. The size of the nozzles is manually identified, and different sizes are placed in separate nozzle boxes. These boxes are then positioned in designated locations to distinguish the nozzle sizes. However, in the use of existing nozzle boxes, it becomes difficult to automatically identify the nozzle sizes in each box using external detection devices when multiple nozzle boxes containing different sizes are mixed together.

[0046] This invention proposes a suction tip box to ensure the automated identification of suction tip specifications.

[0047] Please see Figures 1 to 3 In one embodiment, the suction head box 100 includes a support plate 110 and a support frame. The support plate 110 is provided with a plurality of spaced placement holes 111 for placing suction heads 400. The support frame is located at the bottom of the support plate 110 and is arranged around the periphery of the support plate 110. The side wall of the support frame is provided with a detection port 140. When suction heads 400 of different specifications are placed in the placement holes 111, the length exposed in the detection port 140 is different.

[0048] The pipette tip holder 100 is used to store pipette tips 400, which typically include different sizes such as 50ul, 100ul, 200ul, 300ul, 500ul, and 1000ul. Different sizes of pipette tips 400 indicate different liquid capacities they can draw. The outer diameter of the tail portion 410 of each pipette tip 400 is larger than the outer diameter of the middle portion below the tail portion 410 and the tip portion 420, exhibiting an inverted conical design. Generally, different sizes of pipette tips 400 from the same manufacturer or brand have the same outer diameter of the tail portion 410, but the overall length of different sizes of pipette tips 400 varies.

[0049] The support plate 110 is used to support the suction head 400 and limit its position. In one embodiment, the support plate 110 is provided with a plurality of placement holes 111 evenly spaced, and all placement holes 111 have the same diameter. The diameter of the placement hole 111 is slightly smaller than the outer diameter of the tail 410 of the suction head 400 and larger than the outer diameter of the part where the middle and tail 410 of the suction head 400 meet, so that when any size suction head 400 is placed in the placement hole 111, only the tail 410 of the suction head 400 abuts against the outer periphery of the placement hole 111 and protrudes above the placement hole 111, so that the tails 410 of all suction heads 400 placed on the same support plate 110 are located on the same horizontal plane.

[0050] The support frame provides support for the carrier plate 110 and provides storage space for the suction head 400. In one embodiment, the support frame is arranged around the bottom periphery of the carrier plate 110, and the support frame and the carrier plate 110 together form a suction head box 100. The support frame encloses a receiving cavity, so that when the suction head 400 is placed in the placement hole 111, the middle part and the tip 420 of the suction head 400 can extend into the receiving cavity.

[0051] In one embodiment, the detection port 140 is located on the side wall of the support frame and communicates with the receiving cavity. Since the tails 410 of all the suction heads 400 are located on the same horizontal plane when they are placed in the placement hole 111, the lengths of the suction heads 400 exposed at the detection port 140 are different.

[0052] Normally, when the nozzle 400 is placed in the nozzle box 100, all nozzles 400 placed in each nozzle box 100 are of the same size. However, the nozzles 400 in any two nozzle boxes 100 may not be of the same size. Therefore, an external detection element can be used to detect the overall size of the nozzles 400 in the nozzle box 100 through the detection port 140 to identify the size of the nozzles 400 in the nozzle box 100.

[0053] Taking a 200µl pipette tip 400 and a 1000µl pipette tip 400 as examples, since the length of the 200µl pipette tip 400 is shorter than that of the 1000µl pipette tip 400, in one embodiment, the position and height of the detection port 140 are such that the tip 420 of the 200µl pipette tip 400 cannot be exposed in the detection port 140 or the exposed length is small; the middle part or tip 420 of the 1000µl pipette tip 400 has a larger exposed length in the detection port 140 and can completely block the detection port 140. In one embodiment, a reflective sensor is used to illuminate the detection port 140 of each pipette tip box 100 at a preset height. When the reflective sensor does not receive reflected light, it indicates that the pipette tip box 100 contains a 200µl pipette tip 400; when the reflective sensor receives reflected light, it indicates that the pipette tip box 100 contains a 1000µl pipette tip 400. When the nozzle 400 has multiple specifications, the reflective sensor can perform gradient detection at multiple different preset heights to identify different specifications of nozzle 400. The preset height can be flexibly set according to the size of the detection port 140 and the length of the nozzle 400 of different specifications exposed at the detection port 140, and there are no restrictions here.

[0054] Please see Figure 2 and Figure 3 If the specifications of the suction tip 400 also include 300ul and 500ul, the size and position of the detection port 140 can be changed to ensure that the exposed length of different specifications of the suction tip 400 at the detection port 140 is different. This allows an external detection element to perform overall detection of the specifications of the suction tips 400 in the suction tip box 100 through the detection port 140, thereby identifying the specifications of the suction tips 400 in the suction tip box 100. The size and position of the detection port 140 can be flexibly adjusted according to actual conditions and are not limited here. For example, Figure 2 and Figure 3 The detection port 140 shown has different positions and heights to accommodate the recognition needs of suction heads 400 with different grade specifications. Of course, in other embodiments, image capturing and recognition elements or other external detection elements can also be used to identify the specifications of suction heads 400 through the detection port 140, which is not limited here.

[0055] The technical solution of this utility model involves setting a support plate 110 and a support frame in a suction head box 100. The support plate 110 has multiple spaced placement holes 111 for placing suction heads 400. The support frame is located at the bottom of the support plate 110 and surrounds its periphery. The side wall of the support frame has a detection port 140. When suction heads 400 of different specifications are placed in the placement holes 111, the lengths exposed in the detection port 140 are different. Compared to existing suction head boxes, the technical solution of this utility model provides a detection port 140 on the side wall of the support frame. The tails 410 of suction heads 400 of different specifications can be confined to the placement holes 111, and the tails 410 of all suction heads 400 are located on the same plane, resulting in different lengths of the heads of suction heads 400 exposed in the detection port 140. By utilizing external detection elements, the specifications of the suction head 400 can be determined based on the length of the suction head 400 protruding from the detection port 140, thus ensuring the realization of automated identification of the suction head 400 specifications.

[0056] Please see Figure 1 and Figure 4 In one embodiment, at least two side walls of the support frame are provided with detection ports 140.

[0057] Since the detection port 140 is located on the side wall of the support frame, when it is necessary to test the specifications of the suction head 400 in the suction head box 100, it is necessary to ensure that the orientation of the detection port 140 is opposite to the external detection element in order to ensure that the specifications of the suction head 400 can be tested.

[0058] In one embodiment, each of the two opposite sidewalls of the support frame is provided with a detection port 140, so that if one detection port 140 is blocked, the specifications of the suction head 400 can be detected through the detection port 140 on the other side. In another embodiment, each sidewall of the support frame is provided with a detection port 140. Of course, in other embodiments, one or more detection ports 140 may be provided, and there is no limitation here.

[0059] In this embodiment of the utility model, by providing detection ports 140 on at least two side walls of the support frame, it is possible to further ensure that the suction head box 100 can conveniently detect the specifications of the suction head 400 while storing the suction head 400; and the restriction on the orientation of the suction head box 100 is reduced, making the placement and use of the suction head box 100 more flexible.

[0060] Please see Figure 1 , Figure 4 and Figure 5In one embodiment, the support frame includes a first frame 120 and a second frame 130. The first frame 120 is disposed at the bottom of the support plate 110 and is disposed around the periphery of the support plate 110. The second frame 130 is disposed on the side of the first frame 120 away from the support plate 110 and is disposed around the outer periphery of the first frame 120. The inner diameter of the second frame 130 is larger than the outer diameter of the first frame 120.

[0061] In one embodiment, a first frame 120 and a second frame 130 are sequentially disposed at the bottom of a support plate 110. The second frame 130 protrudes outward relative to the first frame 120 by a ring, giving the suction head box 100 a shoulder 160, and the overall cross-sectional shape of the suction head box 100 is convex. The inner diameter of the second frame 130 is larger than the outer diameter of the first frame 120, allowing the second frame 130 of one suction head box 100 to fit over the first frame 120 of another suction head box 100. The top of the first frame 120 of one suction head box 100 abuts against the shoulder 160 of the other suction head box 100, and / or the bottom of the second frame 130 of one suction head box 100 abuts against the shoulder 160 of the other suction head box 100. In one embodiment, the first frame 120 and the second frame 130 are integrally formed. Of course, in other embodiments, the first frame 120 and the second frame 130 may also be fixedly connected or detachably connected; this is not limited here. The detection port 140 can be set on the side wall of the first frame 120, or on the side wall of the second frame 130, or simultaneously on both the first frame 120 and the second frame 130. The position of the detection port 140 can be flexibly set according to the specifications of the suction head 400 to be placed, and there are no restrictions here.

[0062] Please see Figure 4 and Figure 5 In one embodiment, the outer wall of the first frame 120 is provided with a groove 121, and the inner wall of the second frame 130 is provided with a protrusion 131. The protrusion 131 of the second frame 130 of one suction head box 100 can be movably inserted into the groove 121 of the first frame 120 of the other suction head box 100.

[0063] In one embodiment, the support plate 110 has a rectangular structure, and the cross-sectional shape of the first frame 120 and the second frame 130 is also rectangular. The four corners of the outer wall of the first frame 120 are provided with grooves 121, and the four corners of the inner wall of the second frame 130 are provided with protrusions 131, so that when the second frame 130 of one suction head box 100 is fitted onto the first frame 120 of another suction head box 100, the protrusions 131 can be correspondingly engaged with the grooves 121 and slide along the grooves 121. Of course, in other embodiments, the support plate 110 can also be circular, etc., and the cross-sectional shapes of the first frame 120 and the second frame 130 can be correspondingly arranged. One or more sets of grooves 121 and protrusions 131 can be provided; no limitation is made here.

[0064] The technical solution of this utility model embodiment, by setting a first frame 120 and a second frame 130, with the inner diameter of the second frame 130 being larger than the outer diameter of the first frame 120, allows any two suction head boxes 100 to be nested together, achieving partial overlap of the two suction head boxes 100 for easy stacking and saving storage space of the suction head boxes 100; by setting a groove 121 and a protrusion 131, the nesting between the two suction head boxes 100 can be guided, and relative displacement or deflection between the two suction head boxes 100 can be avoided, improving the reliability of stacking.

[0065] Please see Figure 1 and Figure 4 In one embodiment, the two opposite sidewalls of the first frame 120 are provided with gripping notches 150 for an external robotic arm to insert and grip the suction head box 100.

[0066] In one embodiment, the suction head box 100 is mainly handled and transferred by an external robotic arm. Each of the two gripping parts of the external robotic arm has a protrusion on one side closest to each other. Gripping notches 150 are positioned opposite each other on the two opposite sidewalls of the first frame 120, with the shape of the gripping notches 150 matching the shape of the protrusions, so that the protrusions of the two gripping parts can be inserted into the gripping notches 150 one-to-one. The gripping notches 150 are positioned close to the second frame 130. In one embodiment, each gripping part of the external robotic arm has two sets of protrusions, and two sets of gripping notches 150 are respectively provided on the two opposite sidewalls of the first frame 120. Of course, in other embodiments, the gripping notches 150 can also be located on the second frame 130 and close to the first frame 120; multiple sets of gripping notches 150 can also be provided, with different shapes to accommodate the protrusions of different external robotic arms. No limitation is imposed here.

[0067] The technical solution of this utility model embodiment, by setting a gripping notch 150, facilitates the external robotic arm to grip the suction head box 100, which can reduce the gripping force while ensuring gripping stability, avoids the suction head box 100 from slipping or the suction head box 100 from being deformed due to excessive gripping force, facilitates the transportation of the suction head box 100, and ensures the reliability of the transportation of the suction head box 100.

[0068] Please see Figure 6 and Figure 7This utility model also proposes a suction head storage structure, including a carrier 200 and a suction head box 100 as described in the above embodiments. The carrier 200 has a placement position 210, and the suction head box 100 can be detachably placed in the placement position 210. The specific structure of the suction head box 100 is as described in the above embodiments. Since this suction head storage structure adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0069] During automated experiments conducted on medical automated equipment, when sample addition is required, the sample addition mechanism automatically retrieves the pipette tip 400 from the tip container 100. This may cause the entire tip container 100 to tip over, affecting subsequent operations. Therefore, during sample addition, the tip container 100 needs to be temporarily secured to ensure that it does not move when the pipette tip 400 is retrieved.

[0070] In one embodiment, the carrier 200 is mainly located on the sample application platform. The carrier 200 is detachably connected to the pipette tip box 100, and a placement position 210 is formed by a downward indentation at the center of the carrier 200. When it is necessary to confine the pipette tip box 100 to the placement position 210 for sample application, the pipette tip box 100 is directly placed in the placement position 210 of the carrier 200, and the support frame is connected to the carrier 200. When it is necessary to unload the pipette tip box 100, the support frame is separated from the carrier 200. The size of the placement position 210 is adapted to the cross-sectional size of the support frame on the side away from the support plate 110 to ensure that the support frame can be fitted into the placement position 210. In one embodiment, each carrier 200 is provided with two placement positions 210, which are arranged in parallel and spaced apart. Of course, in other embodiments, each carrier 200 may also be provided with only one or more placement positions 210, which is not limited here.

[0071] Please see Figure 6 and Figure 7 In one embodiment, the suction head storage structure further includes a locking member 300, which is movably disposed on the carrier 200 and located at opposite ends of the placement position 210. A limiting protrusion 170 is provided on the outer periphery of the side of the support frame away from the carrier plate 110. The locking member 300 is used to press against the limiting protrusion 170 to restrict the suction head box 100 to the placement position 210.

[0072] In one embodiment, the limiting protrusion 170 is located at the bottom periphery of the entire suction head box 100, and the limiting protrusion 170 protrudes outward in a ring. In one embodiment, the locking member 300 is telescopically arranged along the first direction of the placement position 210, and at least one locking member 300 is provided at each opposite end of the first direction of the placement position 210. In one embodiment, each placement position 210 corresponds to four locking members 300, and two locking members 300 are provided at each opposite end of the first direction of the placement position 210, with the two locking members 300 spaced apart. Herein, the first direction is the length direction of the placement position 210. Of course, in other embodiments, the first direction may also be the width direction of the placement position 210, which is a direction perpendicular to the length direction; one or more locking members 300 may also be provided at each opposite end of the first direction of the placement position 210, which is not limited here. When the nozzle box 100 needs to be confined in the placement position 210, the locking member 300 extends to press against the limiting protrusion 170, thereby confining the support frame between the placement position 210 and the locking member 300. When the nozzle box 100 needs to be unloaded, the locking member 300 retracts to avoid the limiting protrusion 170, allowing the support frame to leave the placement position 210.

[0073] The technical solution of this utility model embodiment, by setting up a carrier 200, allows the suction head box 100 to be detachably placed in the placement position 210, which can both limit the suction head box 100 and enable the suction head box 100 to move and be replaced; by setting up a locking member 300 and a limiting protrusion 170, the suction head box 100 and the carrier 200 are detachably connected, which improves the ease of use and reliability of the carrier 200.

[0074] Please see Figure 8 and Figure 9 In one embodiment, the locking member 300 includes a guide block 310, an elastic member 320, and a pressing block 330. The guide block 310 is disposed on the carrier 200 and has a guide channel 311, which faces the placement position 210. The elastic member 320 is disposed in the guide channel 311, and one end of the elastic member 320 away from the placement position 210 is connected to the guide block 310. One end of the pressing block 330 is slidably disposed in the guide channel 311 and connected to the other end of the elastic member 320, and the other end of the pressing block 330 is exposed outside the guide channel 311.

[0075] In one embodiment, a guide block 310 is disposed on the carrier 200, close to and above the placement position 210. The guide block 310 has a guide channel 311 inside. The outer surface of the pressing block 330 is in contact with the inner circumferential surface of the guide channel 311, and the pressing block 330 is slidable relative to the guide channel 311. The axis of the guide channel 311 is parallel to the plane of the placement position 210, such that the extension / retraction direction of the elastic member 320 and the movement direction of the pressing block 330 are both parallel to the plane of the placement position 210. The elastic member 320 is capable of elastic deformation; under the elastic force of the elastic member 320, the pressing block 330 tends to move away from the guide block 310 and towards the placement position 210. Under the action of external force, the pressing block 330 can move towards the guide block 310 and away from the placement position 210. When the external force is removed, the pressing block 330 can move towards the placement position 210 under the elastic force of the elastic element 320 to reset. The elastic element 320 can be a spring, a multi-hole elastic body, or rubber, etc., and there are no restrictions here.

[0076] In one embodiment, the end of the pressing block 330 facing the elastic member 320 is provided with a mounting groove 333. The end of the elastic member 320 facing the pressing block 330 extends into the mounting groove 333 and connects with the groove wall of the mounting groove 333, ensuring the connection stability between the pressing block 330 and the elastic member 320. In another embodiment, the carrier 200 is provided with a limiting groove 220, which is located below and connected to the guide channel 311. The end of the pressing block 330 facing the elastic member 320 has a limiting block 334 protruding outward, which extends into the limiting groove 220 to limit the movement of the pressing block 330 and prevent the pressing block 330 from falling out of the guide channel 311. Of course, in other embodiments, the locking member 300 may also include only an elastic abutment block, etc., which is not limited here.

[0077] Please see Figure 9 In one embodiment, the end of the pressing block 330 away from the guide channel 311 has a first inclined surface 331 and a second inclined surface 332. The first inclined surface 331 is located on the side of the pressing block 330 away from the placement position 210, and the second inclined surface 332 is located on the side of the pressing block 330 facing the placement position 210.

[0078] In one embodiment, the end of the first inclined surface 331 away from the guide channel 311 is inclined towards the placement position 210, and the end of the second inclined surface 332 away from the guide channel 311 is inclined towards the placement position 210. The end of the first inclined surface 331 away from the guide channel 311 and the end of the second inclined surface 332 away from the guide channel 311 are connected, so that the side of the pressing block 330 facing the placement position 210 forms a hook-type structure. In one embodiment, there are two first inclined surfaces 331, which are connected together. The end of the first inclined surface 331 closer to the placement position 210 is connected to the end of the second inclined surface 332. Thus, by setting two first inclined surfaces 331, the total area of ​​the first inclined surface 331 can be increased, ensuring that the limiting protrusion 170 can accurately push against the first inclined surface 331; and the two first inclined surfaces 331 can make the entire first inclined surface 331 more gently sloping, ensuring the smooth movement of the pressing block 330 when the limiting protrusion 170 pushes against the first inclined surface 331. The inclination angle of the first inclined surface 331 and the second inclined surface 332 relative to the plane where the placement position 210 is located can be flexibly set according to actual needs, and is not limited here. Of course, in other embodiments, the first inclined surface 331 and the second inclined surface 332 can also be connected by a vertical surface, only one first inclined surface 331 can be set, and the first inclined surface 331 can also be replaced by an arc surface, and is not limited here.

[0079] When it is necessary to restrict the suction head box 100 to the placement position 210, the suction head box 100 is moved to directly above the placement position 210 and then lowered. The limiting protrusion 170 pushes against the first inclined surface 331 of the pressing block 330, causing the pressing block 330 to move towards the guide block 310 to avoid the limiting protrusion 170, so that the suction head box 100 can fit against the placement position 210. After the suction head box 100 fits against the placement position 210, the limiting protrusion 170 moves to below the pressing block 330, and the pressing block 330 loses the pushing force of the limiting protrusion 170. The elastic member 320 drives the pressing block 330 to move towards the suction head box 100 so that the second inclined surface 332 presses against the limiting protrusion 170, thereby restricting the suction head box 100 to the placement position 210. When it is necessary to unload the suction head box 100, use a slightly larger external force to pull the suction head box 100 up, so that the limiting protrusion 170 pushes against the second inclined surface 332 of the pressing block 330, so that the pressing block 330 moves toward the guide block 310, so that the suction head box 100 leaves the placement position 210.

[0080] The technical solution of this utility model embodiment is simple in structure and easy to operate by setting the locking member 300 as a guide block 310, an elastic member 320 and a pressing block 330, which facilitates the automatic loading and unloading of the suction head box 100. By setting the first inclined surface 331 and the second inclined surface 332 on the pressing block 330, the limiting protrusion 170 can more easily push the pressing block 330, which makes it easier for the suction head box 100 to be quickly put into or removed from the placement position 210, thus improving the ease of use of the pressing block 330.
