Description

Technical Field

[0001] This utility model relates to the field of cable tie gun technology, specifically to a cable tie machine with adjustable cutting position. Background Technology

[0002] Cable ties (or bundled ties) are widely used in industrial production, logistics bundling, construction installation, and routine equipment maintenance due to their ease of operation, low cost, and reliable bundling capabilities. To improve the efficiency and standardization of large-scale operations, automatic / semi-automatic cable tying machines (such as cable tie guns and cable tie tools) have emerged, gradually replacing manual bundling. These machines typically integrate feeding, tensioning, locking, and cutting functions, significantly improving operational efficiency and consistency.

[0003] However, practice has shown that existing cable tie machines still have key flaws, severely limiting their applicability, safety, and ease of operation in a wider range of complex scenarios. Among these, the design of the cutting mechanism, particularly the fixed position of the cutting blade, constitutes a major technical bottleneck: most devices on the market have a fixed cutting blade position at the factory, preventing users from flexibly adjusting the position of the cutting blade relative to the cable tie buckle (head) according to the characteristics of the bundled object or the application scenario. This fixed design also makes the length of the cable tie tail unadjustable, greatly reducing the adaptability of the equipment. Utility Model Content

[0004] This invention provides a cable tie machine with adjustable cutting position to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] A cable tie cutting machine with adjustable cutting position for processing cable ties having a buckle and a tail section through which the buckle can pass; comprising a main frame and an adjusting frame;

[0007] The main framework includes:

[0008] Cable tie channels are used to guide and secure the tail section of the cable tie;

[0009] The tightening section is used to clamp the tail section and pull it away from the locking mechanism.

[0010] The cutting section includes a cutting blade configured to cut off the tail section located within the cable tie channel;

[0011] The regulation framework includes:

[0012] The adjustable housing is mounted on the main frame in an adjustable position;

[0013] An abutment portion is provided at one end of the adjusting housing for abutting the latch;

[0014] A fixing component is used to lock the mounting position of the adjusting housing on the main frame;

[0015] Specifically, by adjusting the mounting position of the adjusting housing on the main frame, the distance between the abutment part and the cutting blade is changed, thereby adjusting the retained length of the tail section after cutting.

[0016] Based on the above scheme, the adjusting housing includes a covering part that fits against the side wall of the main frame; a guide block is provided on the inner side of the covering part, and an adjusting groove is provided on the outer side of the main frame, with the guide block embedded in the adjusting groove to achieve linear sliding adjustment.

[0017] Based on the above scheme, the adjusting housing includes a covering part that fits against the side wall of the main frame; an adjusting groove is provided on the inner side of the covering part, and a guide block is provided on the outer side of the main frame, with the guide block embedded in the adjusting groove to achieve linear sliding adjustment.

[0018] Based on the above scheme, the covering part is provided in two sets, and the two sets of covering parts are symmetrically arranged on both sides of the abutting part and respectively attached to the two side walls of the main frame.

[0019] Based on the above solution, the fixing component includes a fixing member and a fixing block, and the fixing block simultaneously locks the adjusting housing and the main frame through the fixing member.

[0020] Based on the above scheme, the outer side of the covering part is provided with multiple snap-fit ​​grooves, and the inner side of the fixing block is provided with a first snap-fit ​​block that matches the snap-fit ​​grooves.

[0021] Based on the above scheme, multiple snap-fit ​​slots are distributed at equal intervals along the sliding direction of the adjusting housing.

[0022] Based on the above scheme, the covering part is provided with an installation hole, and the inner side of the fixing block is provided with a second snap-fit ​​block, which is embedded in the installation hole.

[0023] Based on the above scheme, the cross-section of the adjustment groove is T-shaped, and the guide block is set as a T-shaped protrusion that matches the adjustment groove.

[0024] Based on the above solution, the contact surface between the abutment and the latch is provided with anti-slip texture or elastic buffer layer.

[0025] The advantages of this utility model over the prior art are as follows:

[0026] 1. Significantly improved adaptability: Users can flexibly adjust the position of the cutter relative to the buckle according to actual application needs (such as the size, shape, material, environmental requirements of the bundled object, etc.), thereby precisely controlling the length of the cable tie tail.

[0027] 2. Enhanced operational safety and reliability: By allowing users to cut the tail to an appropriate length, the cable ties are effectively prevented from coming loose due to the tail being too short; this solution allows for sufficient tail length to ensure reliable engagement of the locking mechanism and binding strength, thereby improving overall operational safety.

[0028] 3. Optimize bundling effect and aesthetics: Users can precisely set the tail length according to the aesthetic requirements of the bundled object or specific specifications (such as the tail length standard in some industries) to ensure that the bundling results are neat and uniform and meet the requirements, thereby improving the product's appearance quality and professionalism.

It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0058] like Figure 1 As shown, this utility model provides a cable tie machine 100 for tightening and cutting cable ties. One end of the cable tie 200 is equipped with a buckle 210, and the other end can pass through the buckle 210 to achieve self-locking for binding objects. The method of use is as follows: The user first wraps the cable tie 200 around the object to be bound and manually pre-tightens and secures it by passing the end through the buckle 210; then, the end of the cable tie is inserted into the cable tie machine 100, and the machine automatically completes the final tightening and cuts off the excess, ensuring a secure binding and a neat and aesthetically pleasing end.

[0059] Please refer to the following: Figure 2 , Figure 3 , Figure 4The cable tie machine 100 of this utility model mainly consists of a main frame 10 and an adjusting frame 20. The main frame 10 is gun-shaped, and its internal tightening part 13 and cutting part 14 are responsible for performing the powerful tightening and precise cutting operations of the cable ties 200, respectively; in actual use, the main frame 10 can independently complete these two core functions. The adjusting frame 20 is installed at the front end of the main frame 10. By adjusting the installation position of the adjusting frame 20, the user can flexibly set the reserved length of the cut cable tie tail, thereby significantly improving the adaptability of the cable tie machine 100 to different binding needs. Specifically, the top of the main frame 10 is provided with a guide opening 11, forming a three-sided open receiving space 12, which is specifically used to place and position the cable tie tail. This open design greatly facilitates the quick insertion and accurate positioning of the cable ties 200. The specific process is as follows: Before use, the end of the cable tie is passed through the receiving space 12 of the guide opening 11, so that its main middle section is inside the receiving space 12 and the end extends to the outside; during operation, the tightening part 13 first firmly fixes the cable tie section in the receiving space 12 and pulls it strongly away from the buckle 210 to further tighten the cable tie 200 efficiently and enhance the binding strength; when the tightening reaches the preset requirements, the cutting part 14 is then activated to precisely cut the cable tie section in the receiving space 12 and remove the excess part.

[0060] The main frame 10 includes a gun-shaped frame housing 101, which comprises a first housing 1011, a second housing 1012, and a third housing 1013. The first housing 1011 and the second housing 1012, which are structurally symmetrical, are assembled and fixed together using bolts, screws, and other fasteners. The third housing 1013 is installed at the port of the frame housing 101 (i.e., the gun-shaped main body). Its core function is that when the main frame 10 handles the tail of the cable tie 200 alone, the third housing 1013 abuts against the locking buckle 210 of the cable tie 200, providing necessary support and reaction force for the tightening operation. The third housing 1013 is connected to the first housing 1011 and the second housing 1012 using bolts, screws, and other fasteners; each housing has suitable mounting holes to meet the above connection requirements.

[0061] Please refer to the following: Figure 5 , Figure 6A movable grip 102 is located on the lower part of the frame housing 101, near its gun-shaped handle. The grip 102 is a key control component of this cable tie machine 100. Its core function is that by pressing the grip 102, the user can activate the tightening section 13 and the cutting section 14 inside the main frame 10 to automatically process the cable tie tail placed in the guide opening 11's receiving space 12. Specifically, pressing the grip 102 first triggers the tightening section 13: firmly fixing the cable tie segment in the receiving space 12 and applying traction force away from the locking buckle 210, achieving strong tightening of the cable tie 200. When the tightening force reaches the preset requirement, continued pressing or reaching the end of the stroke will trigger the cutting section 14, precisely cutting the cable tie segment in the receiving space 12 and removing the excess tail.

[0062] When the main frame 10 is operating independently (i.e., without the adjustment frame 20 installed), the third housing 1013 directly abuts against the buckle 210 of the cable tie 200, providing a support reference for the tightening operation. The cutting action of the cutting section 14 is always performed within the receiving space 12 of the guide opening 11, and its cutting point relative to the position of the third housing 1013 abutting against the buckle 210 is fixed. This means that in this mode, the reserved length of the cable tie tail (between the buckle 210 and the cut) after cutting is a constant value. This design ensures the reliability and consistency of basic operations.

[0063] Specifically, the tightening part 13 includes a grip 103, which is located inside the frame housing 101 and is the core component for power input. One end of the grip 103 is pivotally mounted on the frame housing 101 (typically fixed to the first housing 1011 or the second housing 1012) via a first pivot 107, allowing it to rotate about the axis of the first pivot 107. A portion of the grip 103 extends outside the frame housing 101, and a handle 102 is fitted over the portion of the grip 103 that extends outside the frame housing 101; pressing the handle 102 drives the grip 103 to rotate about the first pivot 107.

[0064] The grip 103 has a recessed space (not shown). Within this space, a drive rod 104 is movably mounted via a second pivot 108. The drive rod 104 can rotate freely around the second pivot 108. The other end of the drive rod 104 is movably connected to the middle of a transmission rod 105 via a third pivot 109. One end of the transmission rod 105 is movably connected to the end of a moving rod 106 via a fourth pivot 110. The axes of the first pivot 107, second pivot 108, third pivot 109, and fourth pivot 110 are parallel to each other, ensuring the accuracy and stability of motion transmission. This multi-link mechanism (grip 103-drive rod 104-transmission rod 105-moving rod 106) efficiently converts the rotational motion of the grip 103 into the approximately linear motion of the moving rod 106, and in this process amplifies the user-applied operating force according to the lever principle, generating a powerful tightening traction force for the cable ties 200.

[0065] A limiting through hole 113 is precisely formed on the moving rod 106, and a limiting rod 114 is disposed within the limiting through hole 113. The limiting rod 114 is fixedly installed inside the frame housing 101 (usually its two ends are fixed to the first housing 1011 and the second housing 1012, respectively). This structure ensures that when the handle 102 drives the moving rod 106 to move, the cooperation between the limiting rod 114 and the limiting through hole 113 can strictly constrain the movement trajectory of the moving rod 106, so that it can only move on a preset straight line (or a specific curve) path, ensuring the reliability and repeatability of the action.

[0066] The tightening part 13 also includes an abutment block 128 and a first limiting block 129, with the first limiting block 129 positioned above the abutment block 128. The first limiting block 129 has an L-shaped structure, and its vertical arm cooperates with the abutment block 128 to jointly form the bottom and partial sidewall constraint of the receiving space 12. The abutment block 128 is movably mounted on the moving rod 106. Specifically, the abutment block 128 is rotatably mounted on a specific position on the moving rod 106 via a pivot. A torsion spring (not shown) is disposed between the mounting point of the abutment block 128 and the moving rod 106. One end of the abutment block 128 contacts the third housing 1013. The torsion spring is normally in a compressed state, and its elastic force tends to push the abutment block 128 away from the direction of the first limiting block 129. The side of the abutment block 128 facing the first limiting block 129 (i.e., facing the cable tie 200) is specially provided with a groove structure (not shown) adapted to the shape of the cable tie 200. The design of the groove (such as V-shape, U-shape or toothed) can effectively increase the contact area and friction with the surface of the cable tie 200, so as to achieve reliable limiting and clamping and prevent the cable tie 200 from slipping or coming off during traction.

[0067] Once the cable tie tail is correctly inserted into the receiving space 12 of the guide opening 11, a portion of the cable tie segment is positioned between the L-shaped structure of the abutment block 128 and the first limiting block 129. When the user presses the grip 102 to initiate the tightening process: the moving rod 106 is constrained and begins its preset linear motion. The initial displacement of the moving rod 106 moves away from the third housing 1013, releasing the pre-compression constraint on the torsion spring of the abutment block 128. Under the elastic force released by the torsion spring (or more precisely, the torque generated by the torsion spring releasing from the pre-compression state), the abutment block 128 rotates rapidly about its pivot axis in the direction of the first limiting block 129 (i.e., the "closing" action) until the groove structure on its surface is tightly pressed against the cable tie segment located in the receiving space 12.

[0068] The rotating abutment block 128 and the fixed first limiting block 129 (L-shaped structure) work together to firmly wed (or press) the cable tie 200 within the clamping space formed by them. The groove structure on the abutment block 128 provides crucial limiting and friction-enhancing effects. The moving rod 106 continues its constrained linear motion. Since the abutment block 128 has now moved with the moving rod 106 via its pivot (i.e., after completing the clamping rotation, the position of the abutment block 128 relative to the moving rod 106 is fixed, and it moves as a whole with the moving rod 106), the moving rod 106 drives the clamped and fixed cable tie segment to move away from the locking buckle 210 on the cable tie 200, thereby applying a strong linear traction force to the cable tie 200 and achieving final tightening. This traction force acts directly on the clamped cable tie segment, overcoming the frictional resistance within the locking buckle 210 and tightening the cable tie 200.

[0069] Please refer to the following: Figure 6To ensure automatic reset of the mechanism after each operation, a reset spring 115 and a reset member 116 are configured inside the frame housing 101. The reset member 116 is located on one side of the reset spring 115, with one end abutting against the reset spring 115. The reset member 116 can slide within a preset space inside the frame housing 101 under external force, thereby compressing (storing energy) and releasing (resetting) the reset spring 115. A retaining plate 117 (L-shaped or other suitable shape) is provided at the end of the reset member 116 away from the reset spring 115. A corresponding retaining groove 118 is provided at the end of the grip 103 near the first rotating shaft 107. Part of the retaining plate 117 extends precisely into the retaining groove 118 of the grip 103. When the user presses the handle 102 to drive the grip 103 to rotate around the first rotating shaft 107, the retaining groove 118 on the grip 103 pushes the retaining plate 117, causing the reset member 116 to slide, thereby compressing the reset spring 115 and storing reset energy. This process is synchronized with the tightening action. Simultaneously, the movement of the moving rod 106 releases the constraint on the torsion spring, triggering the abutment block 128 to rotate and clamp the cable tie 200. When the user releases the grip 102, the compressed return spring 115 pushes the reset member 116 to slide in the opposite direction. The locking plate 117 on the reset member 116 pushes the locking groove 118 on the grip 103 in the opposite direction, forcing the grip 103 to rotate in the opposite direction around the first pivot 107, returning to its initial position. Simultaneously, through the linkage of the locking plate 117 and the locking groove 118, and the constraints of the mechanism's own structure, the moving rod 106, drive rod 104, and transmission rod 105 synchronously reset to the standby state. As the moving rod 106 resets to its initial position, the torsion spring is pre-compressed again, and the abutment block 128 rotates in the opposite direction (i.e., "opens") under the pre-compression force of the torsion spring, releasing the clamp on the cable tie 200 and returning to its initial position, preparing for the next insertion of the cable tie 200.

[0070] Please refer to the following: Figure 7 , Figure 8 , Figure 9 , Figure 10The cutting section 14 includes a stabilizing member 119, a limiting body 122, and a cutting lever 130. The stabilizing member 119, as the core linkage component, is approximately triangular in shape. The first corner of the stabilizing member 119 is hinged to the frame housing 101 via a first pivot 107, allowing the stabilizing member 119 to rotate around the first pivot 107. A roller 120 is movably mounted on the second corner of the stabilizing member 119. This roller 120 is the key contact point for triggering the cutting. An adjusting member 121 is connected to the third triangle of the stabilizing member 119. The stabilizing member 119 is movably connected to the transmission rod 105 via a fifth pivot 111. When the drive rod 104 moves the transmission rod 105, the stabilizing member 119 is dragged via the fifth pivot 111, causing it to shift as a whole. The limiting body 122 is fixed inside the frame housing 101 and hinged to the main frame 10 via a sixth pivot 112 (the sixth pivot 112 is also fixedly connected to the first housing 1011 and the second housing 1012). The main body 122 is restricted to rotate around the sixth axis 112.

[0071] A limiting groove 123 is provided on the side of the limiting body 122 facing the stabilizing member 119. The limiting groove 123 is used to accommodate and limit the roller member 120 on the stabilizing member 119. When the roller member 120 is "locked" in the limiting groove 123, the stabilizing member 119 cannot rotate freely around its first axis of rotation 107. An adjusting component 124 is provided at the bottom of the limiting body 122. The adjusting component 124 acts directly on the limiting body 122 to preset and adjust the tightening force of the cable tie 200 required to trigger the cutting (i.e., the force required for the roller member 120 to break free from the limiting groove 123).

[0072] Specifically, the adjustment assembly 124 includes a U-shaped frame 127, a counterweight 125, an adjusting spring 126, a threaded adjusting rod (not shown), and a rotating disk 131. The counterweight 125 is located inside the U-shaped frame 127, and the adjusting spring 126 is located between the U-shaped frame and the counterweight 125, providing initial preload. One end of the threaded adjusting rod is connected to the rotating disk 131, and the other end passes through the U-shaped frame and the adjusting spring 126, and is threadedly connected to the counterweight 125. By rotating the rotating disk 131, the threaded adjusting rod is driven to move the counterweight 125. When the counterweight 125 moves close to the rotating disk 131 inside the U-shaped frame, it compresses the adjusting spring 126, increasing the thrust of the adjusting spring 126 on the U-shaped frame 127. The U-shaped frame 127 transmits this thrust to one end of the limiting body 122, forcing the limiting body 122 to tend to rotate around the sixth pivot 112, thereby increasing the "locking" force of the limiting groove 123 on the roller 120. The greater the preset locking force, the greater the force required by the tightening part 13 to tighten the cable tie 200 so that the displacement generated by the stabilizing member 119 is sufficient to overcome the locking force, ultimately causing the roller 120 to break free from the limiting groove 123 (triggering the cut). Conversely, if the locking force is reduced, a smaller tightening force is needed to trigger the cut.

[0073] The cutting lever 130, located below the moving rod 106, is the core of the power transmission. The cutting lever 130 is hinged to the frame housing 101 via a centrally fixed seventh pivot 132 (connecting the first housing 1011 and the second housing 1012), forming a lever fulcrum. One end of the cutting lever 130 has a concave groove 133 opening towards the stabilizer 119, into which the adjusting member 121 on the stabilizer 119 is precisely embedded; the other end has an extension 134.

[0074] The inner side of the third housing 1013 is provided with a guide groove 136, in which the cutting blade 135 is installed and strictly restricted to moving only in the vertical direction. A limiting opening 137 is opened inside the cutting blade 135, into which the extension 134 of the cutting lever 130 is inserted. A second limiting block 138 is fixedly provided on the top of the third housing 1013. The second limiting block 138 is located directly above the cutting blade 135 and has a cutting opening 139. This cutting opening 139 is located above the upward path of the cutting blade 135. The second limiting block 138, together with the first limiting block 129 and the frame housing 101, constitute an "L"-shaped receiving space 12 for guiding and accommodating the cable tie 200, ensuring the correct positioning of the cable tie tail.

[0075] Before operation, the adjustment component 124 is set with the trigger force. When not tightened or with insufficient force, the roller 120 on the stabilizer 119 is locked by the limiting groove 123, and the stabilizer 119 cannot rotate around the first pivot 107. When the user presses the handle 102, the drive rod 104 drives the stabilizer 119 to move as a whole through the transmission rod 105 and the moving rod 106 to overcome the locking force. As the tightening force of the cable tie 200 increases, the reaction force acting on the stabilizer 119 accumulates continuously. When the tightening force reaches the preset threshold (i.e., the force required for the roller 120 to break free from the limiting groove 123), the stabilizer 119 generates sufficient displacement and torque to overcome the locking force, and the roller 120 breaks free instantly.

[0076] After breaking free, the stabilizing member 119 immediately gains the freedom to rotate rapidly around the first pivot 107. During rotation, the adjusting member 121 at the third corner of the stabilizing member 119 presses down on the concave groove 133 of the cutting lever 130. The downward pressure of the concave groove 133 causes the cutting lever 130 to rotate around the seventh pivot 132. According to the lever principle, the extension 134 of the cutting lever 130 then moves upward. Through the engagement of the extension 134 with the limiting opening 137 on the cutting blade 135, the cutting blade 135 is driven to move rapidly upward within the guide groove 136. The upward-moving cutting blade 135 forms a shearing action with the cutting opening 139 on the second limiting block 138, cleanly and neatly cutting off the taut end of the cable tie.

[0077] After the user releases the grip 102, under the action of the return spring 115: the stabilizing member 119 and the roller member 120 reset, and the roller member 120 falls back into the limiting groove 123 to lock; the stabilizing member 119 rotates to reset, causing the adjusting member 121 to rise; the adjusting member 121 rises and lifts the concave groove 133 of the cutting lever 130, causing it to rotate in the opposite direction around the seventh pivot 132, and the extension 134 of the cutting lever 130 falls down accordingly, causing the cutting blade 135 to move down along the guide groove 136 and return to the initial position.

[0078] Please refer to the following: Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 The adjustment frame 20 is the core module of the cable tie machine 100. Its core function is to precisely control the tail length of the cable tie 200 after it is cut, so as to meet the personalized needs of different users and application scenarios.

[0079] The adjustment frame 20 is located in the port area of ​​the main frame 10 (usually composed of a first housing 1011, a second housing 1012 and a third housing 1013), that is, at the port of the gun-shaped frame housing 101, specifically on one side of the third housing 1013.

[0080] The adjustment frame 20 includes an adjustment housing 201 and a fixing component 202. The fixing component 202 securely locks the adjustment housing 201 to the desired position on the main frame 10. The adjustment housing 201 partially covers the outer side of the port of the main frame 10. An adjustment groove 206 is provided on the inner side of the adjustment housing 201, and a guide block 207 is provided at a corresponding position on the outer side of the main frame 10. The guide block 207 is precisely embedded in the adjustment groove 206. The precise fit between the adjustment groove 206 and the guide block 207 stably restricts the adjustment housing 201 on the main frame 10, while allowing the adjustment housing 201 to slide smoothly and linearly along the axial direction of the guide block 207 (i.e., the length direction of the adjustment groove 206). By changing the sliding position of the adjustment housing 201 on the main frame 10, its installation position can be adjusted. It should be noted that in some embodiments, the positions of the adjustment groove 206 and the guide block 207 can be interchanged, which will not affect the installation of the housing 201; the cross-section of the adjustment groove (206) can be T-shaped, and the guide block (207) can be set as a T-shaped protrusion that matches the adjustment groove (206).

[0081] Specifically, the adjusting housing 201 includes an abutment portion 203, a covering portion 204, and a third limiting block 205. The abutment portion 203 is located at the front end of the adjusting housing 201 and has a plate-like structure. This is a key part that directly contacts the buckle 210 of the cable tie 200 and bears the abutment force during the operation of the cable tie machine 100. The contact surface between the abutment portion 203 and the buckle is provided with anti-slip texture or an elastic buffer layer. The covering portion 204 is designed to fit against the outer surface of the main frame 10. In order to enhance the overall rigidity and shock resistance of the adjusting housing 201 (especially to reduce vibration transmission during cutting), two sets of covering portions 204 are usually provided, respectively connected to the left and right sides of the abutment portion 203. These two sets of covering portions 204 are tightly fitted against the outer surfaces of the first housing 1011 and the second housing 1012 of the main frame 10, respectively. An adjustment groove 206 is formed on the inner surface of the covering part 204, while the corresponding guide block 207 is installed on the outer surfaces of the first housing 1011 and the second housing 1012 of the main frame 10. The third limiting block 205 is integrally formed with the abutment part 203 and the covering part 204. The third limiting block 205 is located on top of the adjustment housing 201, forming a stable "L" shape. When the adjustment housing 201 is in place, the third limiting block 205 precisely covers the cutting opening 139 of the main frame 10. During the cutting process, when the cutting blade moves upward to cut the cable tie 200 located at the cutting opening 139, the hard bottom surface (the horizontal part of the L-shape) of the third limiting block 205 acts as a rigid anvil. The cutting blade and the third limiting block 205 work together to form a shearing force application point similar to scissors, ensuring that the cable tie 200 is cleanly and neatly cut, greatly improving the reliability and efficiency of the cutting.

[0082] When the cable tie machine 100 is operating, the abutment portion 203 of the adjusting frame 20 abuts tightly against the locking buckle 210 of the cable tie 200. Its core function is to directly determine the remaining length of the cable tie 200 after it is cut by precisely adjusting the distance between the abutment portion 203 and the cutting blade 135 mounted on the first housing 1011. Specifically, when the adjusting housing 201 slides, the distance between its abutment portion 203 and the cutting blade 135 changes accordingly.

[0083] Specifically, the fixing component 202 includes a fixing member 208, a fixing block 209, and a plurality of snap-fit ​​grooves 211 disposed on the outside of the covering portion 204; these snap-fit ​​grooves 211 are evenly distributed along the length direction of the adjusting groove 206 (i.e., the sliding adjustment direction). The fixing block 209 has a raised first snap-fit ​​block 212 and a second snap-fit ​​block 213 on its inner side. The covering portion 204 is provided with a mounting hole 210 for the fixing member 208 and the second snap-fit ​​block 213 to pass through. The mounting hole 210 has an opening, which facilitates the installation and positioning of the adjusting housing 20 on the main frame 10. In this embodiment, the fixing member 208 is a bolt, and the size of the mounting hole 210 in the covering portion 204 is larger than the size of the fixing member 208 and the second snap-fit ​​block 213. Therefore, when the adjusting housing 201 is installed on the main frame 10, the second snap-fit ​​block 213 can be accommodated in the mounting hole 210.

[0084] The steps for adjusting the position of the housing 201 are as follows:

[0085] 1. Slide the adjusting housing 201 to the target position on the main frame 10.

[0086] 2. Cover the snap-fit ​​groove 211 area on the outside of the covering part 204 with the fixing block 209.

[0087] 3. Ensure that the first snap-fit ​​block 212 inside the fixing block 209 is embedded in the corresponding snap-fit ​​slot 211.

[0088] 4. Use bolts (fixing parts 208) to pass through the mounting holes 210 on the fixing block 209 and the covering part 204, screw them into the preset threaded holes on the main frame 10 and tighten them. The fixing block 209, the adjusting housing 201 and the main frame 10 are firmly locked together as one by the tightening force of the bolts.

[0089] like Figure 16 As shown:

[0090] An adjusting cylinder 31 is fixedly mounted on the frame housing 101. The adjusting cylinder 31 has external threads machined on its outer side. An adjusting cover 32 is coaxially sleeved on the adjusting cylinder 31, and the inner hole of the adjusting cover 32 has matching internal threads. Through this meshing threaded pair, rotating the adjusting cover 32 drives it to move precisely along the axial direction of the adjusting cylinder 31. It should be noted that at least a portion of the return spring 115 is housed within the internal cavity of the adjusting cylinder 31. When the adjusting cover 32 is rotated, its axial movement directly acts on one end of the return spring 115, thereby changing the initial compression of the spring. This adjustment of compression is equivalent to adjusting the initial preload of the return spring 115, which the user can adjust as needed.

[0091] like Figure 17 As shown:

[0092] The rotating disk 131 is structurally located on the frame housing 101 and is configured to synchronously drive the threaded adjusting rod inside the frame housing 101 to rotate, thereby adjusting the tightening force of the cable tie machine. Multiple locking slots 33 are evenly spaced along the circumferential direction on the outer periphery of the rotating disk 131. These locking slots 33 are completely located inside the frame housing 101, so the user cannot directly observe them when operating the cable tie machine.

[0093] Specifically, a self-locking assembly 34 is disposed inside the frame housing 101. The self-locking assembly 34 includes a self-locking groove 35 formed on the inner wall of the frame housing 101, and a movable self-locking member 36 is housed within the self-locking groove 35. A first spring 37 is installed between the self-locking member 36 and the inner wall of the self-locking groove 35. Under the preload of the first spring 37, the (end) of the self-locking member 36 is continuously pushed in the direction of the rotating disk 131, so that its end can be inserted into and locked into the corresponding locking slot 33 of the rotating disk 131, thereby locking the rotating disk 131. When the user applies sufficient torque to rotate the rotating disk 131 against the force of the first spring 37, the inner wall of the locking slot 33 on the inner wall of the rotating disk 131 will squeeze the end of the self-locking member 36, forcing the self-locking member 36 to compress the first spring 37 and retract into the self-locking groove 35, thereby disengaging its end from the current locking slot 33. As the rotating disk 131 continues to rotate, whenever the next locking slot 33 rotates to a position aligned with the self-locking member 36, the end of the self-locking member 36 will quickly pop out and re-enter the locking slot 33 under the push of the first spring 37, producing a clear shifting sound. This repetitive "embed-disengage-re-embed" process allows the rotating disk 131 to rotate in different gears, thereby adjusting the tightening force of the cable tie machine at different gear levels.

[0094] The self-locking assembly 34 also includes a separate locking function module for completely disabling the adjustment capability of the rotating disk 131 when needed. This locking function module includes a locking part 38 and a locking member 39. The locking part 38 is provided with a locking protrusion 42; the self-locking member 36 has a through hole (not shown) larger than the diameter of the locking member 39 and a locking groove, the locking groove being located on the side of the self-locking member 36 closest to the locking part 38. The locking member 39 passes sequentially through a pre-drilled hole on the frame housing 101 and the through hole on the self-locking member 36, finally engaging with a threaded hole on the locking part 38. In this embodiment, the locking member 39 is a bolt. Because the through hole 40 is larger than the diameter of the locking member 39, the locking member 39 is configured not to obstruct the movement of the self-locking member 36. When the user tightens the locking member 39, the locking part 38 moves axially toward the self-locking member 36 along the locking part 39. As the locking part 38 moves toward the self-locking member 36, the locking protrusion 42 on the locking part 38 inserts into the corresponding locking groove on the self-locking member 36. Once the locking protrusion 42 is fully engaged in the locking groove, it creates a rigid constraint on the self-locking member 36, firmly locking it in its current position and preventing further movement. At this point, no matter how much torque the user applies to try to rotate the rotating disk 131, the rotating disk 131 cannot push the locked self-locking member 36 back. Therefore, the rotation function of the rotating disk 131 is completely locked, and the user can no longer adjust the tightening torque through it.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0096] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
