Description
Technical Field
[0001] This utility model relates to the field of multi-functional tool technology, specifically a convenient multi-functional tool for power applications. Background Technology
[0002] In power operations, workers often need to use a variety of tools to complete line inspections, equipment maintenance, and other operations. Most existing tools are designed for a single function, requiring workers to carry multiple separate tools, which results in low portability and ease of use.
[0003] In the existing technology, the locking structure of the tool is not stable enough. The handle or working end is prone to shaking during use, which affects the accuracy and safety of the operation. The locking operation is relatively complicated and requires additional manual adjustment. At the same time, the working end lacks effective protection when not in use and is easily worn or damaged by collision or friction, which further reduces the practicality and durability of the tool. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a convenient multi-functional tool for power applications, which solves the problems of insufficient stability of the locking structure of the aforementioned tools, easy shaking of the handle or working end during use, affecting the accuracy and safety of the operation; relatively complicated locking operation steps, requiring additional manual adjustment; and lack of effective protection for the working end when not in use, making it prone to wear or damage due to collision or friction.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient multi-functional tool for power applications, comprising: a handle and a working end, wherein the working end is rotatably connected to the handle, and there are two sets of the handle and the working end, and the two sets of working ends are connected by a pin. The design of the two sets of working ends connected by the pin can realize opening and closing action, and can adapt to different power operation scenarios such as clamping wires and stripping wire insulation, thereby improving the tool's adaptability to diverse operation needs; a multi-functional cutting tool is rotatably connected to the inner cavity of the handle.
[0006] The handle has a structure that houses the multi-functional knife, which can be hidden when the knife is not in use to prevent the knife from being exposed and scratching the staff or being damaged by external impacts. At the same time, the rotating connection method allows the staff to quickly unscrew the knife for use according to the work needs. The handle is equipped with a locking mechanism, and the other handle has a slot in its inner cavity.
[0007] The locking mechanism and the slot design provide a structural basis for fixing the handle in the closed position, ensuring that the handle will not open arbitrarily in the closed state, thus ensuring the operational stability of the operator when using the multi-functional tool; the working end is covered with a protective sleeve, which can protect the working end when it is not in use, avoid damage to the sharp parts of the working end, and prevent dust and impurities from adhering and affecting the working accuracy of the working end.
[0008] The locking mechanism includes a square box, with a first piston slidably connected to the inner cavity of the square box. A spring is connected between the first piston and the square box. The spring is designed so that when the airflow driving force disappears, it can drive the first piston to automatically reset, thereby causing the rounded corner block to disengage from the locking groove, providing convenience for the handle to be unfolded again, and ensuring that the locking mechanism has the function of repeated locking and unlocking; a rounded corner block is connected to the outside of the first piston.
[0009] The card slot is adapted to the square box, and the inside of the card slot has a locking groove adapted to the rounded corner card block. The adaptation design of the rounded corner card block and the locking groove can stably restrict the position of the handle through the interlocking action, preventing the handle from becoming loose after locking. At the same time, the rounded corner structure can reduce the jamming when the card block and the locking groove are engaged, improving the smoothness of the locking and unlocking process.
[0010] The square box is connected to a curved pipe on the outside. The curved pipe serves as an airflow transmission channel, which can stably guide the airflow generated inside the square pipe into the square box, ensuring that the airflow can accurately act on the first piston and provide power for the movement of the first piston. The other end of the curved pipe is connected to a square tube, and a piston rod is slidably connected to the inner cavity of the square tube. The sliding cooperation between the square tube and the piston rod constitutes the core structure for airflow generation. The descent of the piston rod can compress the space inside the square tube, thereby generating airflow to drive the movement of the first piston.
[0011] An elastic element connects the piston rod and the square tube. After the protective sleeve is removed and the pressure on the piston rod disappears, the elastic element pushes the piston rod upward to reset, so that the inner cavity of the square tube returns to its initial state. This provides structural preparation for triggering airflow when the protective sleeve is put on again, and ensures the reliability of the locking mechanism for repeated use.
[0012] Preferably, a first magnetic block is provided on the outside of the working end, and a second magnetic block is provided in the inner cavity of the protective sleeve to attract the magnetic block. The magnetic attraction between the first and second magnetic blocks can enhance the connection stability of the protective sleeve when it is put on the outside of the working end, and prevent the protective sleeve from falling off due to vibration or accidental contact during the operation of the multi-functional tool. At the same time, the magnetic attraction can guide the protective sleeve to quickly align with the working end, reduce the time of putting it on, and improve the convenience of using the tool.
[0013] Preferably, the handle has a groove on its outer surface, and a rubber pad is provided in the inner cavity of the groove. The groove design allows the fingers of the operator to naturally conform to the shape of the handle when holding it, improving the fit and comfort of the grip. The rubber pad in the groove can increase the friction between the hand and the handle, preventing the tool from slipping due to sweaty hands during operation. At the same time, the rubber material has a certain elasticity, which can relieve hand fatigue caused by holding the handle for a long time.
[0014] Preferably, the multi-functional tool includes a screwdriver, a cutting knife, a pry bar, and a marker pen. The multi-functional tool is connected to the handle via a pin. This multi-functional tool integrates multiple tool types to meet various needs in electrical work, such as tightening screws, cutting insulating materials, prying parts, and marking work positions. Workers do not need to carry multiple individual tools, effectively reducing tool load and improving work portability. The pin connection ensures the tool can rotate flexibly, facilitating quick switching between tool types according to work requirements. A rubber sleeve is provided at the junction of the pin and the handle. The rubber sleeve increases the damping during pin rotation, allowing the multi-functional tool to remain stably at the required angle after being unscrewed, preventing the tool from rotating arbitrarily during operation and affecting operation. Simultaneously, the rubber sleeve reduces wear between the pin and the handle, extending the tool's service life.
[0015] Preferably, the protective sleeve is provided with a rubber sleeve on the outside, and the rubber sleeve has anti-slip texture. The rubber sleeve and the anti-slip texture cooperate to increase the friction when the operator holds the working end covered by the protective sleeve, ensuring stable tool grip when using the multi-functional tool, avoiding tool slippage or operational deviation due to hand slippage, and improving work safety. The top of the inner cavity of the working end is the wire stripping end, and the bottom of the inner cavity of the working end is the cutting end. The working end integrates the wire stripping end and the cutting end, which can complete basic electrical operations such as stripping the insulation layer of wires and cutting wires or insulation materials without changing tools, reducing the number of tool switching and improving work efficiency. Moreover, the functional divisions at both ends are clearly defined, making it easy for operators to quickly identify and use the corresponding functional ends.
[0016] Preferably, the inner cavity of the protective sleeve is provided with a curved groove, which is adapted to the outer surface of the working end. This adaptation design ensures that the protective sleeve fits tightly to the working end when it is put on. On the one hand, it can prevent the protective sleeve from shaking outside the working end, ensuring that the piston rod can be accurately driven to descend when the protective sleeve is put on, and ensuring that the locking mechanism is stably triggered. On the other hand, it can fully cover the outer contour of the working end, improving the protection effect on sharp parts such as the stripping end and cutting end of the working end, preventing them from being damaged or scratching the workers.
[0017] Compared with the prior art, this utility model provides a convenient multi-functional tool for power applications, which has the following beneficial effects:
[0018] This portable multi-functional power tool integrates multiple tool functions through two sets of rotatably connected handles and working ends connected by pin shafts, along with a multi-functional cutting tool with a rotating inner cavity in the handle. This eliminates the need for workers to carry multiple separate tools, greatly improving the convenience of carrying and using the tool.
[0019] This portable multi-functional tool for electric use features a locking mechanism within the handle's inner cavity that engages with a slot in another set of handle cavities. When the multi-functional tool is needed, the handle is closed, the locking mechanism is inserted into the slot, and then a protective sleeve covering the working end drives the piston rod downwards. Airflow generated by the square tube enters the square box through a curved tube, pushing the first piston and causing the rounded corner block to engage in the locking groove. This stabilizes the position of the handle and the working end, preventing shaking during multi-functional tool use and ensuring operational accuracy and safety. The locking operation is also directly triggered by the protective sleeve, simplifying the operation. Furthermore, the protective sleeve protects the working end, reducing wear or damage when not in use. The overall structure is compact. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a technical solution, please refer to Figure 1 , Figure 2 and Figure 3A portable multi-functional tool for power applications includes: a handle 1 and a working end 12. The working end 12 is rotatably connected to the handle 1. There are two sets of handle 1 and working end 12, and the two sets of working end 12 are connected by a pin. The design of the two sets of working end 12 connected by a pin can realize opening and closing action, which can adapt to different power operation scenarios such as clamping wires and stripping wire insulation, and improve the adaptability of the tool to diverse operation needs. A multi-functional cutting tool 2 is rotatably connected to the inner cavity of the handle 1.
[0026] The handle 1 has a structure that houses the multi-functional knife 2 inside, which can hide the knife when it is not in use, preventing the knife from being exposed and scratching the staff or being damaged by external impacts. At the same time, the rotating connection method allows the staff to quickly unscrew the knife for use according to the work needs. The handle 1 has a locking mechanism 3 inside, and the other set of handles 1 has a slot inside.
[0027] The locking mechanism 3 and the slot design provide a structural basis for fixing the position of the handle 1 after it is closed, ensuring that the handle 1 will not open at will when it is closed, thus ensuring the operational stability of the operator when using the multi-functional knife 2; the working end 12 is covered with a protective sleeve 4, which can protect the working end 12 when it is not in use, preventing damage to the sharp parts of the working end 12, and preventing dust and impurities from adhering and affecting the working accuracy of the working end 12.
[0028] The locking mechanism 3 includes a square box 31, with a first piston 32 slidably connected to the inner cavity of the square box 31. A spring is connected between the first piston 32 and the square box 31. The spring is designed so that when the airflow driving effect disappears, such as when the protective cover 4 is removed, it can drive the first piston 32 to automatically reset, thereby causing the rounded corner block 33 to disengage from the locking groove, providing convenience for the handle 1 to be unfolded again, and ensuring that the locking mechanism 3 has the function of repeated locking and unlocking; the rounded corner block 33 is externally connected to the first piston 32.
[0029] The card slot is compatible with the square box 31. The inside of the card slot is provided with a locking groove that is compatible with the rounded corner card block 33. The matching design of the rounded corner card block 33 and the locking groove can stably restrict the position of the handle 1 through the interlocking action, preventing the handle 1 from becoming loose after locking. At the same time, the rounded corner structure can reduce the jamming when the card block and the locking groove are engaged, and improve the smoothness of the locking and unlocking process.
[0030] The square box 31 is connected to the outside of a curved pipe 34, which serves as an airflow transmission channel. The curved pipe 34 can stably guide the airflow generated in the square pipe 35 into the square box 31, ensuring that the airflow can accurately act on the first piston 32 and provide power for the movement of the first piston 32. The other end of the curved pipe 34 is connected to a square pipe 35, and a piston rod 36 is slidably connected to the inner cavity of the square pipe 35. The sliding cooperation between the square pipe 35 and the piston rod 36 constitutes the core structure for airflow generation. The descent of the piston rod 36 can compress the space inside the square pipe 35, thereby generating airflow to drive the movement of the first piston 32.
[0031] An elastic element 37 is connected between the piston rod 36 and the square tube 35. After the protective sleeve 4 is removed and the pressure on the piston rod 36 is eliminated, the elastic element 37 can push the piston rod 36 upward to reset, so that the inner cavity of the square tube 35 returns to its initial state. This provides structural preparation for triggering airflow when the protective sleeve 4 is put on next time, and ensures the reliability of the locking mechanism 3 for repeated use.
[0032] The working end 12 is provided with a first magnetic block on its outside, and the inner cavity of the protective sleeve 4 is provided with a second magnetic block that attracts the magnetic block. The magnetic attraction between the first magnetic block and the second magnetic block can enhance the connection stability of the protective sleeve 4 when it is put on the outside of the working end 12, and prevent the protective sleeve 4 from falling off due to vibration or accidental contact during the operation of the multi-functional tool 2. At the same time, the magnetic attraction can guide the protective sleeve 4 to quickly align with the working end 12, reduce the time of putting it on, and improve the convenience of using the tool.
[0033] The handle 1 has a groove 11 on its outside, and a rubber pad is provided in the inner cavity of the groove 11. The design of the groove 11 allows the fingers of the operator to naturally conform to the shape of the handle 1 when holding it, improving the fit and comfort of the grip. The rubber pad in the groove 11 can increase the friction between the hand and the handle 1, preventing the tool from slipping due to sweaty hands during operation. At the same time, the rubber material has a certain elasticity, which can relieve hand fatigue caused by holding the handle 1 for a long time.
[0034] The multi-functional tool 2 includes a screwdriver, a cutting knife, a pry bar, and a marker. The multi-functional tool 2 is connected to the handle 1 via a pin. Integrating multiple tool types, the multi-functional tool 2 can meet various needs in electrical work, such as tightening screws, cutting insulating materials, prying parts, and marking work positions. Workers do not need to carry multiple separate tools, effectively reducing the amount of tools they need and improving work portability. The pin connection ensures the tool can rotate flexibly, facilitating quick switching between tool types according to work requirements. A rubber sleeve is provided at the junction of the pin and the handle 1. The rubber sleeve increases the damping during pin rotation, allowing the multi-functional tool 2 to remain stably at the required angle after being unscrewed, preventing the tool from rotating arbitrarily during operation and affecting operation. At the same time, the rubber sleeve reduces wear between the pin and the handle 1, extending the tool's service life.
[0035] The protective sleeve 4 is covered with a rubber sleeve with anti-slip texture. The rubber sleeve and anti-slip texture work together to increase the friction when the operator holds the working end 12 covered by the protective sleeve 4, ensuring a stable grip when using the multi-functional knife 2 and preventing the tool from slipping or deviating from its intended operation, thus improving work safety. The top of the inner cavity of the working end 12 is the wire stripping end, and the bottom of the inner cavity is the cutting end. The working end 12 integrates the wire stripping end and the cutting end, allowing basic electrical operations such as stripping the insulation layer of wires and cutting wires or insulation materials to be completed without changing tools, reducing the number of tool switching times and improving work efficiency. Moreover, the functional areas at both ends are clearly defined, making it easy for operators to quickly identify and use the corresponding functional ends.
[0036] The inner cavity of the protective sleeve 4 is provided with a curved groove, which is adapted to the outer surface of the working end 12. The adaptation design of the curved groove to the outer surface of the working end 12 ensures that the protective sleeve 4 fits tightly to the working end 12 when it is put on. On the one hand, it can prevent the protective sleeve 4 from shaking outside the working end 12, and ensure that the piston rod 36 can be accurately driven to descend when the protective sleeve 4 is put on, ensuring that the locking mechanism 3 is stably triggered. On the other hand, it can fully cover the outer contour of the working end 12, improve the protection effect on the sharp parts of the working end 12 such as the stripping end and the cutting end, and prevent them from being damaged or scratching the staff.
[0037] When using this solution, the protective cover 4 is removed, and electrical work is performed through the working end 12. When the multi-functional tool 2 is needed, first unscrew the multi-functional tool 2, then close the handle 1 so that the locking mechanism 3 on the outside of one side of the handle 1 is inserted into the slot of the other side of the handle 1. Then, put the protective cover 4 on the outside of the working end 12. When the protective cover 4 is put on, it will drive the piston rod 36 to descend, and then cooperate with the square tube 35 to generate airflow. The airflow enters the inside of the square box 31 through the bent tube 34, and drives the first piston 32 to move the rounded corner block 33 to move and lock into the inside of the locking groove, locking the position of the handle 1. At this time, the positions of the handle 1 and the working end 12 are locked and protected. The operator can hold one end of the working end 12 and perform electrical work through the multi-functional tool 2.
