Technical Field

[0001] This application relates to the field of tube cutting technology, and in particular to a tube cutting device. Background Technology

[0002] During interventional procedures, various types and lengths of flexible catheters are used, so the catheters need to be cut to size according to clinical requirements. A qualified catheter requires a smooth, burr-free cut surface, no uncut metal wires, and no metal wire delamination.

[0003] When cutting the tube, the metal mandrel passes through the inner diameter of the tube to be cut, the tube is placed on the cutting pad, the size to be cut is measured by the graduated steel ruler, the utility knife is equipped with a special blade, and the blade is pushed forward or backward at the position to be cut, causing the tube to rotate and achieve the purpose of cutting to a certain size.

[0004] However, this cutting method involves directly cutting the tube with a hand-held cutter, which can easily lead to problems such as skewed cutting, delamination of the metal wire, and spiral cutting surfaces on the outer tube.

[0015] In one embodiment of this application, the mounting base has a tool relief groove, which is recessed into the top wall of the slide groove;

[0016] The fastener can be moved into or out of the tool relief groove to raise or lower the tool relative to the support assembly.

[0017] In one embodiment of this application, the mounting base has symmetrically arranged slide grooves, the cutting assembly includes two sliders, the two sliders are movably disposed in the two slide grooves respectively, and a fastener is disposed on the cutter and connected to the two sliders;

[0018] And / or, the cutting assembly also includes a first fastener that passes through the mounting base and is secured to the support assembly.

[0020] The tube cutting device also includes a limiting member, which is disposed in the limiting groove and protrudes from the support component in a third direction. The limiting member can abut against the end of the tube to be cut.

[0021] In one embodiment of this application, there are multiple limiting grooves, which are spaced apart along a first direction. The distance between the limiting groove and the cutting component along the first direction is the same as or different from that between two adjacent limiting grooves.

[0022] And / or, the limiting groove includes a first mounting groove and a second mounting groove, the second mounting groove extends along a second direction, the first mounting groove is disposed at one end of the second mounting groove and protrudes from the first mounting groove along a first direction; the limiting member includes a first limiting plate and a second limiting plate, the second limiting plate extends along a second direction and is disposed in the second mounting groove, the first limiting plate is located at one end of the second limiting plate and protrudes from the second limiting plate along a first direction, and the first limiting plate is installed in the second mounting groove.

[0023] In one embodiment of this application, the support assembly includes a support base and a support plate disposed on the support base, the support plate having a limiting groove extending in a second direction;

[0024] The cutting component is set on the support base, the anti-slip pad is set on the support plate, and the tube to be cut is placed on the support plate along the first direction.

[0025] In one embodiment of this application, the support plate has a plurality of placement slots, which extend along a first direction and are spaced apart along a second direction. Each placement slot is used to accommodate a tube to be cut.

Detailed Implementation

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] See Figures 1 to 3 This application provides a tube cutting device 100. The tube cutting device 100 is used to cut the tube 200 to be cut into a conduit of a predetermined length. Figure 1This is a schematic diagram of a tube cutting device 100 according to an embodiment of this application from one perspective. Figure 2 for Figure 1 The diagram shown illustrates the pipe cutting device 100 cutting the pipe body 200 to be cut. Figure 3 for Figure 1 A schematic diagram of the tube cutting device 100 shown from another perspective.

[0044] In one embodiment of this application, the tube body 200 to be cut is a soft tube body required for interventional surgery. After the tube body 200 to be cut is cut into a catheter of a predetermined length, the catheter can be used as a soft catheter product for interventional surgery.

[0045] Typically, a mandrel is inserted into the tube body 200 to be cut in this type of process. During cutting, the mandrel needs to be cut to a certain depth into the inner surface of the tube body 200 and the outer surface of the mandrel to be cut into a conduit of a predetermined length. Furthermore, the cut surface of the tube body 200 after cutting is smooth and burr-free, and the metal wire of the mandrel in the tube body 200 is not cut to avoid delamination and deformation of the metal wire, thus ensuring the performance of the conduit.

[0046] Of course, in other embodiments of this application, the pipe body 200 to be cut may also be other pipe materials that need to be cut, such as rigid plastic pipes, flexible hoses or other pipe materials that need to ensure a flat cut surface.

[0047] This application only uses the example of the tube cutting device 100 cutting the soft tube to be used, and takes the tube to be cut 200 as a substitute for the soft tube used in interventional surgery. The structure and principle of the tube cutting device 100 for cutting other types of tubes are essentially the same as the structure and principle for cutting soft tubes, and will not be repeated hereafter.

[0048] The tube cutting device 100 of this application can cut the tube 200 to be cut after it is limited, prevent the tube 200 to be cut from moving during the cutting process, ensure the stability of the cutting process, and prevent the tube 200 to be cut from deflecting, ensuring a flat cut surface and avoiding situations such as metal wire delamination and deformation, or cutting out a spiral end face.

[0049] See Figures 1 to 3In one embodiment, the tube cutting device 100 includes a support assembly 110, a cutting assembly 120, and an anti-slip pad 130. The support assembly 110 is used to receive the tube 200 to be cut along a first direction. The cutting assembly 120 is disposed on the support assembly 110 and is movable relative to the support assembly 110 along a second direction to cut the tube 200. The anti-slip pad 130 is disposed on the support assembly 110 and located below the cutting assembly 120. The anti-slip pad 130 can contact the tube 200 to be cut and limit its movement. The tube 200 to be cut is placed on the support assembly 110 and the anti-slip pad 130 along the first direction and extends through the underside of the cutting assembly 120. When the cutting assembly 120 moves along the second direction, it can cut the tube 200 into a conduit.

[0050] The support assembly 110 serves as the base of the pipe cutting device 100, supporting all its components. Thus, all components of the pipe cutting device 100 are mounted on the support assembly 110, forming a unified whole. In use, the pipe cutting device 100 is fixed to an external support platform, such as an operating platform or support table. The operator uses the pipe cutting device 100 on the support platform to cut the pipe 200.

[0051] like Figures 1 to 3 As shown, the support component 110 extends along a first direction, a second direction, and a third direction. The first direction is the length direction (left-right direction) of the support component 110, the second direction is the width direction (front-back direction) of the support component 110, and the third direction is the thickness direction (up-down direction, top-bottom direction) of the support component 110. These first, second, and third directions also apply to other components of the tube cutting device 100, which will not be described in detail below.

[0052] The cutting assembly 120 is a component of the tube cutting device 100 that cuts the tube 200 to be cut. The cutting assembly 120 is disposed on the support assembly 110 along a second direction, and is movable relative to the support assembly 110 along the second direction to cut the tube 200 to be cut on the support assembly 110. The tube 200 to be cut is placed on the support assembly 110 along a first direction, and the cutting assembly 120 is located above the tube 200. When the cutting assembly 120 moves along the second direction, it can cut the tube 200 to be cut.

[0053] Understandably, after the tube body 200 to be cut is placed on the support assembly 110, it may move along the first direction during the cutting process, resulting in an uneven cut surface and affecting the quality of the conduit. Therefore, after the tube body 200 is placed on the support assembly 110, it needs to be limited. In this application, the tube cutting device 100 also includes an anti-slip pad 130, which is disposed on the support assembly 110 and located below the cutting assembly 120.

[0054] That is, the anti-slip pad 130 is disposed between the support assembly 110 and the cutting assembly 120. The anti-slip pad 130 can play an anti-slip role. The tube body 200 to be cut is placed on the support assembly 110 and the anti-slip pad 130 along the first direction. After the tube body 200 to be cut comes into contact with the anti-slip pad 130, the anti-slip pad 130 can increase the friction between itself and the tube body 200 to be cut, restricting the movement of the tube body 200 to be cut along the first direction, so as to confine the tube body 200 to be cut on the support assembly 110.

[0055] After the anti-slip pad 130 comes into contact with the tube body 200 to be cut, it can limit the movement of the tube body 200. Only by applying a large force can the tube body 200 be moved. If the tube body 200 is subjected to a small force, it cannot move due to the limiting effect of the anti-slip pad 130. Thus, during the cutting process of the cutting assembly 120, the anti-slip pad 130 can limit the movement of the tube body 200, preventing it from moving in the first direction.

[0056] In this way, when the cutting component 120 moves, it can cut the fixed tube 200 to be cut without any deviation, ensuring a flat cut surface and avoiding issues such as wire delamination, deformation, or spiral end faces. Furthermore, the tube cutting device 100 has a simple structure and is easy to operate, making it convenient for operators to cut the tube 200.

[0057] In one embodiment, the anti-slip pad 130 is a rubber pad. That is, the anti-slip pad 130 is made of rubber material. This ensures the anti-slip effect of the anti-slip pad 130 and reliably limits the cutting of the tube body 200. Of course, in other embodiments of this application, the anti-slip pad 130 may also be provided with an anti-slip coating or anti-slip protrusions, as long as it can play an anti-slip limiting role for the tube body 200 to be cut.

[0058] See Figures 1 to 4In one embodiment, the support component 110 has a limiting groove 111 extending along a second direction. The limiting groove 111 is located on the side of the cutting component 120 and has a preset distance from the cutting component 120. The tube cutting device 100 also includes a limiting member 140, which is disposed in the limiting groove 111 and protrudes from the support component 110 along a third direction. The limiting member 140 can abut against the end of the tube 200 to be cut. Figure 4 for Figure 1 The diagram shows the cooperation between the support component 110 and the limiting component 140 in the tube cutting device 100. Figure 5 for Figure 4 The top view of the support component 110 and the limiting member 140 shown.

[0059] The support assembly 110 has a recessed limiting groove 111 located on the side of the cutting assembly 120 and with a predetermined distance between it and the cutting assembly 120. A limiting member 140 cooperates with the limiting groove 111 to further limit the tube body 200 to be cut. The limiting member 140 is disposed in the limiting groove 111 and protrudes from the surface of the support assembly 110 in a third direction. That is, after the limiting member 140 is installed in the limiting groove 111, the top of the limiting member 140 protrudes from the surface of the support assembly 110.

[0060] After the tube body 200 to be cut is placed along the first direction on the support assembly 110 and the anti-slip pad 130, the end of the tube body 200 to be cut can abut against the protruding limiting member 140. At this time, the limiting member 140 can stop and limit the tube body 200 to be cut, restricting the movement of the tube body 200 to be cut toward the limiting member 140. After the limiting member 140 and the anti-slip pad 130 cooperate, the tube body 200 to be cut can be limited, so that the tube body 200 to be cut can be reliably fixed to the support assembly 110, making it convenient for the cutting assembly 120 to cut the tube body 200.

[0061] The cooperation between the limiting member 140 and the cutting assembly 120 can also cut conduits of a predetermined length. The tube body 200 to be cut is placed on the support assembly 110 and the anti-slip pad 130 from the left side of the cutting assembly 120, while the limiting member 140 and the limiting groove 111 are located on the right side of the cutting assembly 120. Figures 1 to 4 As shown, the end of the tube body 200 to be cut passes through the lower part of the cutting assembly 120 and abuts against the limiting member 140. After the cutting assembly 120 cuts the tube body 200 to be cut, the cutting assembly 120 cuts it into a conduit of a predetermined length, and the distance between the cutting assembly 120 and the limiting member 140 is the length of the cut conduit.

[0062] In other words, a limiting groove 111 is provided on the side of the cutting assembly 120 away from the installation direction of the tube body 200 to be cut, and a protruding limiting member 140 is provided in the limiting groove 111. The tube body 200 to be cut abuts against the limiting member 140 to stop and limit the tube body 200 to be cut. At the same time, the length of the conduit is limited by the distance between the limiting groove 111 and the cutting assembly 120, so that the cutting assembly 120 can cut the tube body 200 to be cut into a conduit of a predetermined length, so that the length of the conduit meets the usage requirements, eliminating the need for a special ruler for measurement, simplifying the cutting steps, and making it convenient for operators.

[0063] See Figures 1 to 5 In one embodiment, there are multiple limiting grooves 111, which are spaced apart along a first direction. The distance between the limiting groove 111 and the cutting component 120 along the first direction may be the same as or different from that between two adjacent limiting grooves 111. That is, each limiting groove 111 extends along a second direction, and the multiple limiting grooves 111 are spaced apart along the second direction. In this way, the distances from the multiple limiting grooves 111 to the cutting component 120 are different, allowing for the cutting of conduits of different lengths.

[0064] Specifically, when a certain length of conduit needs to be cut, the limiting member 140 is installed into the limiting groove 111 corresponding to that length. At this time, the distance between the limiting member 140 and the cutting component 120 is equal to the length of the conduit. Then, the tube body 200 to be cut is placed on the support component 110 and the anti-slip pad 130, and the end of the tube body 200 to be cut is abutted against the limiting member 140. The tube body 200 to be cut is then cut by the cutting component 120 to form a conduit of the required length.

[0065] Furthermore, in this application, "multiple" refers to at least two. The distance between the limiting groove 111 and the cutting component 120 along the first direction, and the distance between adjacent limiting grooves 111 along the first direction, can be the same. Moreover, when the number of limiting grooves 111 is at least three, the distance between the limiting groove 111 and the cutting component 120 along the first direction, and the distance between adjacent limiting grooves 111 along the first direction, can be partially the same and partially different. In this way, the tube body 200 to be cut can be cut according to actual usage requirements.

[0066] In this embodiment, there are three limiting grooves 111, which are the first limiting groove 1111, the second limiting groove 1112, and the third limiting groove 1113 along the direction gradually away from the cutting component 120. The distance between the first limiting groove 1111 and the cutting component 120 along the first direction is equal to the distance between the first limiting groove 1111 and the second limiting groove 1112 along the first direction, and also equal to the distance between the second limiting groove 1112 and the third limiting groove 1113 along the first direction.

[0067] For example, the distance between the first limiting groove 1111 and the cutting assembly 120 along the first direction is 10mm. When a 10mm conduit needs to be cut, the limiting member 140 is placed in the first limiting groove 1111, and the end of the tube body 200 to be cut is abutted against the limiting member 140, and then cut using the cutting assembly 120. When a 20mm conduit needs to be cut, the limiting member 140 is placed in the second limiting groove 1112, and the end of the tube body 200 to be cut is abutted against the limiting member 140, and then cut using the cutting assembly 120. When a 30mm conduit needs to be cut, the limiting member 140 is placed in the third limiting groove 1113, and the end of the tube body 200 to be cut is abutted against the limiting member 140, and then cut using the cutting assembly 120.

[0068] Of course, in other embodiments of this application, the distance between the first limiting groove 1111 and the cutting component 120 along the first direction can be other than other distances, to cut the conduit to the required size. Of course, in other embodiments of this application, the number of limiting grooves 111 can be four or even other numbers, so that the tube cutting device 100 can cut conduits of different lengths. Of course, in other embodiments of this application, the distance between the limiting groove 111 and the cutting component 120 along the first direction can also be different from the distance between adjacent limiting grooves 111 along the first direction.

[0069] See Figures 1 to 5 In one embodiment, the limiting groove 111 includes a first mounting groove 1114 and a second mounting groove 1115. The second mounting groove 1115 extends along a second direction, and the first mounting groove 1114 is disposed at one end of the second mounting groove 1115 and protrudes from the first mounting groove 1114 along a first direction. The limiting member 140 includes a first limiting plate 141 and a second limiting plate 142. The second limiting plate 142 extends along a second direction and is disposed in the second mounting groove 1115. The first limiting plate 141 is located at one end of the second limiting plate 142 and protrudes from the second limiting plate 142 along a first direction. The first limiting plate 141 is installed in the second mounting groove 1115.

[0070] The shape of the limiting groove 111 is substantially the same as that of the limiting member 140, so that the limiting member 140 can be accurately installed in the limiting groove 111, thereby enabling the limiting member 140 to accurately stop and limit the tube body 200 to be cut. The second mounting groove 1115 and the second limiting plate 142 are the main components of the tube body 200 to be cut. The second mounting groove 1115 extends along the second direction, and the second limiting plate 142 is disposed in the second limiting groove 1112 and protrudes from the surface of the support assembly 110, thereby stopping and limiting the tube body 200 to be cut.

[0071] A first mounting groove 1114 is provided at the end of the second mounting groove 1115, and a first limiting plate 141 is provided at the end of the second limiting plate 142. The first mounting groove 1114 and the first limiting plate 141 extend along the first direction. The cooperation between the first limiting plate 141 and the first mounting groove 1114 can limit the second limiting plate 142 along the second direction, preventing the second limiting plate 142 from moving in the second mounting groove 1115, thereby ensuring the limiting effect of the second limiting plate 142 on the tube body 200 to be cut.

[0072] In one embodiment, the first limiting plate 141 and the second limiting plate 142 are connected in a T-shape and are adapted to the shape of the limiting groove 111. Of course, in other embodiments of this application, the first limiting plate 141 and the second limiting plate 142 are connected in an L-shape or other shapes and are adapted to the shape of the limiting groove 111, as long as the second limiting plate 142 can be limited. Optionally, the first limiting plate 141 and the second limiting plate 142 are an integral structure.

[0073] See Figures 1 to 5 In one embodiment, the support assembly 110 includes a support base 112 and a support plate 113 disposed on the support base 112. The support plate 113 has a limiting groove 111 extending in a second direction. A cutting assembly 120 is disposed on the support base 112, and an anti-slip pad 130 is disposed on the support plate 113. The tube body 200 to be cut is placed on the support plate 113 in a first direction.

[0074] The support base 112 serves as the base plate of the support assembly 110. The support base 112 is positioned on an external support platform. The support plate 113 is positioned above the support base 112, providing support for the support plate 113. An anti-slip pad 130 is positioned on the support plate 113. The cutting assembly 120 is positioned on the support base 112, above the anti-slip pad 130. The tube body 200 to be cut is placed along a first direction on the anti-slip pad 130 and the support plate 113.

[0075] Furthermore, a limiting groove 111 extending along the second direction is provided on the support plate 113 to limit the tube body 200 to be cut, so that when the cutting assembly 120 moves relative to the support plate 113, it can cut a tube of a predetermined length. Optionally, both the support plate 113 and the support base 112 are plate-shaped.

[0076] See Figures 1 to 5In one embodiment, the support plate 113 has a plurality of placement slots 1132, each extending along a first direction and spaced apart along a second direction. Each placement slot 1132 is used to accommodate a tube body 200 to be cut. Each placement slot 1132 extends along the first direction, and the plurality of placement slots 1132 are spaced apart along the second direction. Thus, each placement slot 1132 can accommodate one tube body 200 to be cut.

[0077] After the tube body 200 to be cut is limited by the anti-slip pad 130 and the limiting member 140, the cutting assembly 120 can move along the second direction to cut multiple tube bodies 200 to be cut in the placement slots 1132 simultaneously. In this way, the tube cutting device 100 can cut multiple tube bodies 200 to be cut at one time, thereby obtaining multiple conduits at once. This improves the cutting efficiency of the tube bodies 200 to be cut.

[0078] See Figures 1 to 5 In one embodiment, the placement groove 1132 extends at least along the first direction through one end of the support plate 113 away from the limiting groove 111. That is, the placement groove 1132 extends at least along the first direction to the left end of the support plate 113. This facilitates the installation of the tube body 200 to be cut into the placement groove 1132. In this embodiment, the placement groove 1132 extends through both ends of the support plate 113 along the first direction.

[0079] See Figures 1 to 5 In one embodiment, the support plate 113 has multiple protrusions 1131, and adjacent protrusions 1131 form a placement groove 1132. Multiple protrusions 1131 are provided on the surface of the support plate 113, and adjacent protrusions 1131 and the surface of the support plate 113 can form a placement groove 1132. Thus, tubes 200 of different diameters can be placed in the placement groove 1132 and limited by the anti-slip pad 130 and the limiting member 140, thereby enabling the cutting assembly 120 to cut tubes 200 of different diameters. Therefore, the tube cutting device 100 of this application can cut tubes 200 of different diameters to obtain conduits of the same diameter but different lengths to meet practical needs.

[0080] Of course, in other embodiments of this application, the support plate 113 has a plurality of recesses, each recess being a placement groove 1132. The recesses are rectangular or arc-shaped, and can also accommodate tubes 200 of different diameters to be cut.

[0081] See Figures 1 to 5In one embodiment, the support base 112 has a recessed fixing groove 1121, and the support plate 113 is disposed in the fixing groove 1121. The surface of the support base 112 has the recessed fixing groove 1121. After the support plate 113 is disposed in the fixing groove 1121, the fixing groove 1121 can engage the support plate 113, thereby fixing the support plate 113 into the fixing groove 1121 and preventing the position of the support plate 113 relative to the support base 112 from shifting, thus achieving accurate positioning of the tube body 200 to be cut.

[0082] In one embodiment, the support base 112 is provided with scale lines (not shown) along a first direction. That is, scale lines are directly provided on the support base 112, and these scale lines extend along the first direction. In this way, when cutting conduits of other lengths, the scale lines can be used directly for measurement, eliminating the need for a ruler, which facilitates the measurement of the cutting length and makes it easier for operators to operate.

[0083] See Figures 1 to 5 In one embodiment, the support plate 113 has a recessed receiving groove 1133 at the position corresponding to the cutting component 120, and an anti-slip pad 130 is disposed in the receiving groove 1133. The middle region of the support plate 113 has a recessed receiving groove 1133, which corresponds to the cutting component 120, and the anti-slip pad 130 is disposed in the receiving groove 1133. Thus, after the tube body 200 to be cut is installed in the placement groove 1132, it can contact the anti-slip pad 130 in the receiving groove 1133, while not increasing the height of the tube body 200 to be cut, ensuring the accuracy of cutting the tube body 200.

[0084] In one embodiment, the support assembly 110 further includes a second fastener (not shown) that fixes the support base 112 to an external support platform. The second fastener passes through the support base 112 and is installed onto the support platform to fix the pipe cutting device 100 to the support platform, preventing the position of the pipe cutting device 100 from shifting during subsequent cutting of the pipe body 200 to be cut. Optionally, the second fastener is a screw or the like.

[0085] See Figures 1 to 3 , Figure 6 , Figure 7 In one embodiment, the cutting assembly 120 includes a mounting base 121 and a cutter 122 movably disposed in the mounting base 121 along a second direction. Anti-slip pads 130 are provided on the mounting base 121 and the cutter 122 respectively. The mounting base 121 extends along the second direction and is fixed to the support assembly 110. When the cutter 122 moves relative to the mounting base 121 along the second direction, it can cut the tube body 200 to be cut. Figure 6 for Figure 1 The diagram shows the cutting component 120 in the tube cutting device 100 from one perspective. Figure 7for Figure 6 The diagram shows the cutting component 120 from another perspective.

[0086] Mounting base 121 is a seat for fixing the cutting assembly 120, and is fixedly disposed on the support base 112 of the support assembly 110. Cutter 122 is a component for cutting the tube body 200 to be cut. Cutter 122 is disposed in mounting base 121, and can move in a second direction in mounting base 121. The bottom of cutter 122 protrudes from mounting base 121 and contacts the tube body 200 to be cut on support plate 113.

[0087] The tube body 200 to be cut is placed on the support plate 113 and the anti-slip pad 130, and after abutting against the limiting member 140, the cutter 122 is pushed to move in the second direction so that the cutter 122 can contact and cut the tube body 200 to be cut. That is, the mounting base 121 is fixedly set on the support base 112 and supports the cutter 122 so that the cutter 122 can move in the second direction and cut the tube body 200 to be cut. Optionally, the cutter 122 is a blade capable of cutting.

[0088] In one embodiment, the cutting assembly 120 further includes a first fixing member, which passes through the mounting base 121 and is fixed to the support assembly 110. The first fixing member can fix the mounting base 121 to the support base 112 to prevent the position of the mounting base 121 from shifting, thereby enabling the cutter 122 to move accurately in the second direction, thus accurately cutting the tube body 200 to be cut. Optionally, the first fixing member is a screw or the like.

[0089] See Figures 1 to 3 , Figure 6 and Figure 7 In one embodiment, the mounting base 121 has a groove 1211 disposed along a second direction. The cutting assembly 120 also includes a slider 123 and a fastener 124, the slider 123 being movably disposed in the groove 1211 and the fastener 124 connecting the slider 123 and the cutter 122.

[0090] A groove 1211 is disposed on the side of the mounting base 121 along the second direction. A slider 123 is movably disposed in the groove 1211 on the side of the mounting base 121. A fastener 124 can securely connect the slider 123 and the blade. Thus, when the operator pushes the slider 123, the slider 123 can move along the groove 1211. Furthermore, the slider 123 can drive the blade 122 to move along the groove 1211 via the fastener 124, thereby allowing the blade to move along the second direction to cut the tube body 200 to be cut.

[0091] Optionally, the slider 123 has anti-slip textured surfaces. This prevents slippage when the operator pushes the slider 123, ensuring cutting accuracy. It is worth noting that the structural form of the slider 123 is not limited in principle, as long as the slider 123 can move along the groove 1211. Optionally, the fastener 124 can be a connecting bolt, connecting pin, connecting shaft, etc.

[0092] See Figures 1 to 3 , Figure 6 and Figure 7 In one embodiment, the mounting base 121 has symmetrically arranged slide grooves 1211, the cutting assembly 120 includes two sliders 123, the two sliders 123 are movably disposed in the two slide grooves 1211 respectively, and the fastener 124 is disposed on the cutter 122 and connected to the two sliders 123.

[0093] In other words, the two sliders 123 are symmetrically arranged on both sides of the mounting base 121 and are movably installed into the corresponding mounting slots. In this way, the operator can push the sliders 123 on both sides at the same time, and then push the cutter 122 to move along the second direction through the sliders 123, so as to facilitate the cutter 122 to cut the tube body 200 to be cut.

[0094] Of course, in other embodiments of this application, the number of sliders 123 may also be one. In one embodiment, the number of fasteners 124 is two, and the reliable connection between slider 123 and cutter 122 is achieved by the two fasteners 124. Of course, in other embodiments of this application, the number of fasteners 124 may also be one or other numbers.

[0095] See Figures 1 to 3 , Figure 6 and Figure 7 In one embodiment, the mounting base 121 has a tool relief groove 1212 recessed into the top wall of the slide groove 1211. The fastener 124 can move into or out of the tool relief groove 1212 to raise or lower the tool 122 relative to the support assembly 110.

[0096] The retraction groove 1212 is provided on the top wall of the slide groove 1211 and is recessed upwards. When installing the tube body 200 to be cut, push the slider 123 to move so that the fastener 124 is aligned with the retraction groove 1212. Then, lift the slider 123 upwards so that the slider 123 drives the cutter 122 to lift. At this time, the tube body 200 to be cut can pass under the cutter 122 and abut against the limiting member 140. Then, press the slider 123 downwards and push the slider 123 to move along the slide groove 1211 to cut the tube body 200 to be cut.

[0097] In use, the tube cutting device 100 of this application moves the slider 123 along the slide groove 1211 to the position of the knife retraction groove 1212, and lifts the slider 123 upward so that the fastener 124 enters the knife retraction groove 1212. Then, the tube 200 to be cut, through which the mandrel passes, is installed in the placement groove 1132 of the support plate 113 along the first direction, and the end of the tube 200 to be cut passes through the bottom of the cutter 122 and abuts against the limiting member 140 in the corresponding limiting groove 111.

[0098] Then, press down on slider 123 to make cutter 122 cut downwards to a specific depth into the inner surface of the tube body 200 to be cut and the outer surface of the mandrel. Next, push slider 123 along slide groove 1211 to move one distance to one side, then move it the same distance to the other side. Lift slider 123 upwards so that fastener 124 is in the cutter relief groove 1212. At this point, the cut guide tube can be withdrawn, and the tube cutting device 100 completes one working cycle.

[0099] When simultaneously cutting five tubes 200, the tubes 200 with mandrels inserted are placed in the five placement slots 1132 of the support plate 113 along the first direction, with the ends of the tubes 200 abutting the limiting member 140. Then, the slider 123 is pressed down, causing the cutter 122 to cut downwards to a specific depth into the inner surface of the tube 200 and the outer surface of the mandrel. Subsequently, the slider 123 is pushed along the slide groove 1211 to move a certain distance to one side, and then to the other side by the same distance. The slider 123 is lifted upwards, so that the fastener 124 is in the retraction groove 1212. At this time, the cut guide tube can be removed, and the tube cutting device 100 completes one working cycle. Repeating the cutting process can satisfy the simultaneous cutting of five tubes 200.

[0100] The tube cutting device 100 of this application uses an anti-slip pad 130 to limit the movement of the tube 200 to be cut on the support assembly 110, thereby restricting the movement of the tube 200 along the first direction and preventing it from moving during the cutting process, thus ensuring the stability of the cutting process. In this way, when the cutting assembly 120 moves, it can cut the fixed tube 200 without causing it to skew, ensuring a flat cut surface and avoiding issues such as wire delamination, deformation, or the cutting of spiral ends. Furthermore, the tube cutting device 100 has a simple structure, is easy to operate, and facilitates the cutting of the tube 200.

[0101] Meanwhile, by cooperating with the limiting member 140 and multiple limiting grooves 111, the tube body 200 to be cut can be stopped and limited, and the tube body 200 to be cut can be positioned at various lengths to cut conduits of different lengths. Moreover, multiple tube bodies 200 to be cut can be cut at the same time, improving work efficiency. Furthermore, the mounting base 121 supports the cutter 122, and the cutter 122 can move relative to the mounting base 121 in the second direction, avoiding contact between the blade of the cutter 122 and the operator, reducing the risk of cuts.

[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
