Description

Technical Field

[0001] This utility model relates to the field of binding and cutting technology, specifically to a cable tie clamp. Background Technology

[0002] In the current market, common cable pliers generally suffer from structural redundancy, often integrating too many non-core components, such as complex multi-stage transmission mechanisms and redundant locking components. This not only results in a large overall tool size and poor portability but also significantly increases the probability of errors during the mating of internal parts. The complexity of the structure directly affects the tool's operational stability, easily leading to malfunctions such as blade misalignment and jamming during continuous cutting. Especially when dealing with cable ties of different sizes, these tools often struggle to accurately position the cutting point, frequently resulting in failure to cut, excessively long residual sections, or the cable tie flying off after cutting, severely impacting operational accuracy.

[0003] At the operational level, most existing cable pliers require users to use both hands to complete multiple steps such as opening, positioning, and cutting. Some products have poorly designed leverage points, which can easily cause hand fatigue after prolonged use. Furthermore, the complex internal structure increases the difficulty of daily maintenance, making cleaning and parts replacement inconvenient, further reducing actual efficiency. Therefore, existing cable pliers have shortcomings in structural design, ease of operation, and maintainability, making it difficult to fully meet the actual needs of efficient and precise cutting in scenarios such as industrial production and home organization. Utility Model Content

[0004] This utility model provides a solution to 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 clamp includes a fixing part, a fixing housing, and a torque adjustment mechanism, a first movable shaft, and a second movable shaft disposed within the fixing housing;

[0007] Furthermore, the torque adjustment mechanism includes an adjusting component, a tension spring, and a fixed block. The fixed block is connected to the adjusting component, one end of the tension spring is connected to the fixed block, and the other end is connected to the first movable shaft. The tension of the tension spring is changed by the adjusting component to adjust its prestress.

[0008] Furthermore, the cutting assembly includes a blade drive assembly and a cutting blade, the blade drive assembly being connected to a first movable shaft and configured to drive the cutting blade to perform cutting;

[0009] Furthermore, the drive unit is pivotally connected to the fixed unit via a second movable pivot and maintains contact with the first movable pivot; the drive unit is provided with a tightening component.

[0010] Furthermore, when the operating force applied to the drive unit is less than the prestress of the tension spring, the pivot drive tightening assembly of the drive unit tightens the cable tie;

[0011] Furthermore, when the operating force is greater than the prestress, the drive unit pushes the first movable shaft to slide, thereby driving the cutter to perform the cutting action through the cutter head drive assembly.

[0012] The advantages of this utility model over the prior art are as follows:

[0013] In terms of torque adjustment, its adjustment mechanism can precisely match the binding force required for different bundled items, and the current torque level can be viewed intuitively, avoiding the problems of blind torque adjustment and limited adaptability in existing technologies. This provides a stable force control basis for subsequent cable tie tightening and cutting actions. Regarding cutting performance, the coordinated design of the blade drive assembly and the cutting assembly effectively improves the smoothness of the cutting action and the flatness of the cut surface. It can adapt to various types of cable ties, overcoming the shortcomings of existing technologies such as laborious cutting, poor cutting effect, and limited applicability to a single type of cable tie. In the cable tie tightening stage, the tightening assembly can reliably lock the cable tie in one direction, preventing slippage during tightening. It can also adapt to cable ties with different cross-sectional shapes, solving the pain points of low tightening reliability and narrow adaptability in existing technologies. The optimized design of the guiding and resetting structure, on the one hand, enables stable guidance of cable ties of different widths, and on the other hand, ensures the smoothness of the resetting action of the drive housing and blade assembly, avoiding resetting jamming and improving the overall smoothness of the device's operation. In terms of user experience, both the fixed handle and the drive handle feature an ergonomic, non-slip design, reducing fatigue during prolonged operation. The integrated "tighten first, then cut" operation simplifies the cumbersome step-by-step process of existing technologies, improving operational efficiency. From an overall reliability perspective, the device's internal structure, including top rod support and stop positioning, effectively prevents component misalignment, reduces mechanical wear, and extends the device's lifespan. Ultimately, this achieves a dual improvement in the cable tie pliers' functional adaptability and operational stability across various application scenarios. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] like Figure 1 and Figure 2As shown, a cable tie clamp 1 includes a fixing part 2 and a driving part 3. The fixing part 2 includes a fixing housing 100, and the driving part 3 includes a driving housing 200. Both the fixing housing 100 and the driving housing 200 are three-sided enclosed groove-shaped housings with a bottom. The fixing housing 100 is enclosed by a horizontal bottom wall 101, side walls 102 vertically erected on both sides of the bottom wall 101 and arranged parallel to each other, and an end wall 103 vertically erected at one end of the bottom wall 101 and connecting to the ends of the side walls 102, forming a single-end open groove cavity structure. The fixing housing 100 includes a fixing handle 104 for the user to hold. The fixing handle 104 is fitted with an anti-slip sleeve, and the anti-slip sleeve has an ergonomic grip buckle. The anti-slip sleeve can increase the frictional resistance between the hand and the handle to prevent slippage during operation, and the grip buckle conforms to the hand's grip contour to reduce fatigue during long-term operation. A window 105 is provided on the side wall 102 of the fixed handle 104, and a fixing hole 106 is provided at the end of the bottom wall 101.

[0029] See Figure 3 and Figure 5 In this embodiment, a torque adjustment mechanism 107 is provided inside the fixed handle 104. The torque adjustment mechanism 107 includes an adjustment knob 108, an adjustment component, a tension spring 110, a gear indicator plate 111, a stop component 112, and a fixing block 113. The adjustment component is preferably an adjustment screw 109. A fixing hole 106 is provided on the fixed handle 104. The adjustment knob 108 is embedded in the fixing hole 106, with one end exposed for user operation and the other end extending into the fixed handle 104 and connected to the adjustment screw 109 via a threaded connection. When the adjustment knob 108 is rotated, the adjustment screw 109 can move axially. The adjusting screw 109 has a stop 112, a gear position indicator plate 111, and a fixing block 113 arranged sequentially from the side closest to the adjusting knob 108. The stop 112 supports the end of the tension spring 110 near the adjusting knob 108. The gear position indicator plate 111 is fixed inside the fixed handle 104 and has a gear position mark. When the user drives the torque adjustment mechanism 107, the current torque position can be seen through the window 105. The fixing block 113 is located at the end of the adjusting screw 109 away from the knob, and one end of the tension spring 110 is sleeved on the fixing block 113.

[0030] like Figure 3 and Figure 4 As shown, the fixed housing 100 has a first sliding groove 114 and a second sliding groove 115. A first movable rotating shaft 116 is adapted to be installed in the first sliding groove 114. The first movable rotating shaft 116 can rotate within the constrained space of the first sliding groove 114 and can also reciprocate along the length direction of the first sliding groove 114. A second movable rotating shaft 117 is adapted to be installed in the second sliding groove 115. The second movable rotating shaft 117 follows the motion constraint of the second sliding groove 115. The end of the tension spring 110 away from the fixed block 113 is assembled on the first movable rotating shaft 116.

[0031] See Figure 6 When the adjustment knob 108 is turned, the adjustment screw 109 moves axially and drives the fixed block 113 to move synchronously. The tension spring 110 is sleeved on the outside of the fixed block 113, and the fixed block 113 is located inside the tension spring 110. Since the bottom diameter a of the tension spring 110 is smaller than its overall diameter b, when the fixed block 113 moves downward, it can push the bottom end of the tension spring 110 to move downward synchronously. However, the top end of the tension spring 110 cannot move downward because it is fixedly connected to the first movable rotating shaft 116, which causes the tension spring 110 to undergo axial tensile deformation. The stretched tension spring 110 applies tension to the first movable shaft 116. The first movable shaft 116 transmits the force to the associated structure inside the fixed housing 100 through a combination of rotation and sliding motion, thus providing a power basis for the cutting action. During the adjustment process, the gear indicator plate 111 provides real-time feedback on the current gear as the adjusting screw 109 moves. The stop 112 provides support and positioning for the components on the adjusting screw 109, ensuring the structural stability of each component when they are linked, preventing component misalignment, and improving the reliability of the mechanism operation.

[0032] like Figure 7 and Figure 8 As shown, the fixed housing 100 also houses a blade drive assembly 118 and a cutting assembly 119. The cutting assembly 119 includes a blade limiting block 120 and a cutting blade 121. The cutting blade 121 and the blade limiting block 120 are positioned above the blade drive assembly 118 and both abut against it. The fixed housing 100 is provided with a push rod 122 and a fixed shaft 123. The push rod 122 is located below the blade drive assembly 118 and is used to support the blade drive assembly 118 to prevent it from shifting position or misaligning due to excessive tension from the tension spring 110. The fixed shaft 123 is equipped with the blade limiting block 120, which provides positioning support for the blade limiting block 120 and ensures the guiding stability of the cutting blade 121 during sliding. At the top of the fixed housing 100, a guide port 126 is provided at the position of the cutting component 119. The guide port 126 can guide the cable tie into the cutting area and at the same time assist the cutting component 119 in positioning the cable tie, improving the stability of the cable tie during cutting, and working with the cutter 121 to complete the cutting action.

[0033] For details, see Figure 8To ensure the stability of the cutting blade 121's trajectory and the smoothness of its cutting action during the pushing process, a guide rail 124 is provided on the cutting head limit block 120 at the contact point between the cutting head drive assembly 118 and the cutting head limit block 120. A corresponding notch 125 is provided on the cutting head drive assembly 118. The notch 125 is inserted into the guide rail 124 to form a sliding fit, thereby limiting the lateral offset of the cutting head drive assembly 118 and guiding it to move stably along the extension direction of the guide rail 124. This allows the power to be smoothly transmitted to the cutting blade 121, reducing the risk of jamming and skewing when the cutting blade 121 slides along the cutting head limit block 120.

[0034] In other embodiments of this utility model (not shown in the figures), the original fixed cutter 121 and guide rail 124 mating structure can be eliminated, and the cutter can be replaced with a combination of "rolling blade + cutter shaft". The cutter head limiting block 120 is replaced with an arc-shaped cutter groove (replacing the original guide rail 124), and the two ends of the cutter shaft are embedded in the cutter groove to form a rolling fit. The cutter head driving assembly 118 is connected to the cutter shaft through a connecting rod, pushing the cutter shaft to roll along the arc-shaped cutter groove. When the cutter head driving assembly 118 moves upward, it drives the rolling blade to roll along the arc-shaped cutter groove, replacing the original "sliding shearing" with "rolling shearing". The cable tie is gradually cut by the rolling blade under the positioning of the guide port 126 and the guide channel 207. The power transmission path of the cutter head driving assembly 118 remains unchanged, only the original "pushing the cutter to slide" is transformed into "pushing the cutter shaft to roll" through the connecting rod. The top rod 122 can still support the cutter head driving assembly 118, and the fixed shaft 123 can still position the modified cutter head limiting block 120 (arc-shaped cutter groove structure).

[0035] like Figure 2 , Figure 3 and Figure 8As shown, the drive housing 200 is pivotally mounted on the second movable shaft 117 of the fixed housing 100, and one side of it abuts against the first movable shaft 116, forming a connecting fulcrum for force transmission. The drive housing 200 includes a drive handle 201, on which an anti-slip sleeve is fitted, and the anti-slip sleeve is provided with an ergonomic grip buckle; the drive handle 201 includes a vertical rod 202 and a rotating shaft 203. A return spring 204 is provided on the vertical rod 202, one end of the return spring 204 is fixedly connected to the vertical rod 202, and the other end is fixedly connected to the cutter head drive assembly 118. When the user grips the drive handle 201, the drive housing 200 drives the second movable shaft 117 to move along the second slide groove 115. Through its contact with the first movable shaft 116, the drive housing 200 pushes the first movable shaft 116 upwards along the first slide groove 114 as it moves. Since the cutter head drive assembly 118 is mounted on the first movable shaft 116, the sliding of the first movable shaft 116 synchronously drives the cutter head drive assembly 118 to move, thereby pushing the cutting blade 121 out along the guide rail of the cutter head limiting block 120, completing the cutting operation. During this process, the return spring 204 deforms with the swing of the drive handle 201, accumulating return potential energy. When the cutting action is completed and the user releases the drive handle 201, the return spring 204 releases its deformation potential energy, pulls the upright 202 to drive the drive housing 200 to swing in the opposite direction around the second movable shaft 117, and at the same time pulls the first movable shaft 116 back along the first slide groove 114 through the abutment relationship, so that the cutter head drive assembly 118 and the cutting blade 121 are synchronously reset to the initial position, creating a preparation state for the next cutting action.

[0036] In other embodiments of this utility model (not shown in the figures), the fixed guide port 126 can be replaced with movable baffles and adjusting bolts. One movable baffle is provided on each side of the guide port, and the spacing between the baffles is adjusted by the bolts. A polytetrafluoroethylene wear-resistant layer is pasted on the inner wall of the guide channel 207 to reduce the frictional resistance of the cable tie. Alternatively, a torsion spring can be used to replace the return spring 204. The return spring 204 on the original upright 202 is removed, and a torsion spring is fitted onto the second movable shaft 117. One end of the torsion spring is fixed to the fixed housing 100, and the other end is fixed to the drive housing 200. After adjusting the spacing of the guide port baffles to match the cable tie width, the cable tie is smoothly guided through the wear-resistant guide channel. When the drive handle 201 swings, the torsion spring rotates with the second movable shaft 117, generating deformation and accumulating potential energy. After releasing the handle, the torsion spring drives the drive housing 200 to rotate in the opposite direction to reset, simultaneously pulling the first movable shaft 116 back down, thus achieving the linkage reset of the cutter head drive assembly 118 and the cutting blade structure. The movable baffle structure remains at the position of the cutting assembly 119 at the top of the fixed housing 100, without changing the cable tie guide path; the reset force of the torsion spring is transmitted through the second movable rotating shaft 117, which is consistent with the reset logic of the original reset spring 204, and both can achieve synchronous reset of the drive housing 200 and the cutter head assembly.

[0037] like Figure 8 and Figure 9 As shown, a tightening component is pivotally mounted on the rotating shaft 203. The tightening component is preferably a gripper seat 205, and a protrusion 206 is provided at the end of the gripper seat 205 away from the guide port 126. When the cable tie clamp 1 is not in operation, the fixing part 2 and the driving part 3 are tightly fitted together, and the gripper seat 205 is close to the cutter head limiting block 120. The cutter head limiting block 120 limits the gripper seat 205, thereby restricting the rotation of the gripper seat 205. When the fixing part 2 and the driving part 3 are separated by the rotation of the driving housing 200, the limiting effect of the cutter head limiting block 120 on the gripper seat 205 is released, and the gripper seat 205 can rotate freely around the rotating shaft 203, providing conditions for the subsequent tightening of the cable tie.

[0038] See Figure 8 The top of the drive housing 200 is provided with a guide channel 207, which is opposite to the guide opening 126 at the top of the fixed housing 100. When the cable tie is cut, it can first pass through the guide opening 126 and then smoothly enter the guide channel 207. Through the coordinated cooperation of the guide opening 126 and the guide channel 207, the cable tie is stably guided from the time it is introduced to the time it is cut, which further ensures the accuracy of the cable tie position during cutting.

[0039] The operation process and operating principle of the cable tie clamp 1 are as follows: Before operation, the user needs to adjust the torque according to the required binding force (e.g., 50kg) of the bundled item: Rotate the adjustment knob 108 on the fixed handle 104, and drive the adjustment screw 109 to move axially through the threaded engagement, pushing the tension spring 110 sleeved on the fixed block 113 to stretch (the top of the spring is fixed to the first movable rotating shaft 116 and cannot move down), so that the tension of the tension spring 110 matches the binding force of the set gear. The user can observe the markings on the gear indicator 111 through the window 105 to confirm that the torque gear meets the requirements, laying the foundation for force control for "tightening first and then cutting".

[0040] During operation, the cable tie is first passed through the guide opening 126 at the top cutting assembly 119 of the fixed housing 100, and then enters the guide channel 207 oppositely set at the top of the drive housing 200. The two work together to ensure accurate positioning of the cable tie. At this time, the edge of the cable tie will contact the protrusion 206 at the end of the clamp seat 205 away from the guide opening 126. The protrusion 206 can be embedded in the surface texture of the cable tie or hold the edge of the cable tie to form a one-way locking structure to prevent the cable tie from slipping in subsequent actions. The user then holds the fixed handle 104 and the drive handle 201 with both hands (the anti-slip sleeve on the outside of the handle increases friction and prevents slipping, and the grip buckle fits the hand shape to reduce fatigue). Two actions are triggered according to the grip strength: if the user's grip strength is less than the set binding force (e.g., less than 50kg), the grip strength is insufficient to overcome the tension of the tension spring 110, and the drive housing 200 cannot move upward along the second slide groove 115, but can only rotate around the second movable pivot 117, thereby opening the fixed part 2 and the drive part 3; during this process, the limiting effect of the cutter head limiting block 120 on the gripper seat 205 is released, and the gripper seat 205 can rotate freely around the pivot 203. Since the protrusion 206 has already clamped the cable tie, the rotation of the gripper seat will drive the cable tie to move synchronously through the protrusion, gradually shortening the effective length of the cable tie between the guide opening 126 and the guide channel 207, realizing the tightening operation of the cable tie until the degree of tightening of the cable tie reaches the state corresponding to the set binding force.

[0041] If the user continues to apply force, making the grip force greater than the set binding force (e.g., greater than 50kg), the grip force can overcome the tension of the tension spring 110. Simultaneously, the drive housing 200 rotates around the second movable shaft 117, causing the second movable shaft 117 to move upwards along the second slide groove 115. The drive housing 200, through its contact with the first movable shaft 116, pushes the first movable shaft 116 to slide upwards synchronously along the first slide groove 114. Because the cutter head drive assembly 118 is installed on the first movable shaft 116, both move upwards accordingly. Furthermore, the cutter head drive assembly 118 forms a sliding fit with the guide rail 124 of the cutter head limiting block 120 through the notch 125, preventing lateral displacement and ensuring smooth power transmission to the cutter 121. This pushes the cutter 121 out along the guide rail, and, in conjunction with the cutter head limiting block 120 positioned by the fixed shaft 123 and the cutter head drive assembly 118 supported by the bottom top rod 122, completes the cable tie cutting operation.

[0042] During the cutting process, the return spring 204 on the upright 202 of the drive handle 201 deforms and accumulates potential energy as the handle swings. When the user releases the drive handle 201 after the cutting is completed, the return spring 204 releases the deformation potential energy, pulls the upright 202 and causes the drive housing 200 to swing in the opposite direction around the second movable shaft 117, so that the fixed part 2 and the drive part 3 re-fit. At the same time, it pulls the first movable shaft 116 back down, causing the cutter head drive assembly 118 and the cutter 121 to return to the initial position. The gripper seat 205 is also re-limited by the cutter head limiting block 120 as the fixed part and the drive part fit together. The engagement relationship between the protrusion 206 and the cable tie is released, and the entire device returns to the ready-to-operate state, ready for the next cable tie tightening-cutting cycle.

[0043] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.
