Description

Technical Field

[0001] The present application relates to the technical field of electric switches, and in particular to an electric switch with improved usage efficiency. Background Art

[0002] An electric wrench is a wrench powered by a power source or battery. It is a tool for tightening high-strength bolts. Currently, the wrenches commonly used by people are hand tools that use the principle of leverage to twist bolts, screws, nuts and other threaded fasteners. They are mainly divided into impact wrenches, shear wrenches, angle wrenches, hydraulic wrenches, etc. They play an important role in the steel structure installation industry. Their main function is to install high-strength bolts.

[0003] After checking the announcement number: CN 218254898 U, a torque-adjustable impact wrench is disclosed. This technology discloses "including an impact electric wrench, a PLC controller is installed at one end of the impact electric wrench in the horizontal direction, a display screen that is electrically connected is provided on the PLC controller, a bump is installed at the top of the impact electric wrench, the impact electric wrench is fixedly connected to a universal tube through the bump thread, a scanner is installed at one end of the universal tube away from the bump, the scanner is wirelessly connected to the PLC controller, and the circumferential side wall of the impact electric wrench is sleeved with an annular strip and other technical solutions. This application has a novel structure, which not only improves the docking efficiency between the impact wrench and the parts, but also improves the stability of the impact wrench during the rotation process, and is suitable for promotion and other technical effects".

[0004] With respect to the above-mentioned related technologies, the inventors believe that most electric wrenches currently in use are prone to excessive motor load torque, resulting in excessive motor current and torque overload, causing motor damage, and if operated improperly, the strong torque makes it impossible for the operator to control the electric wrench in time, which may cause serious limb injuries to the operator in severe cases, increasing the danger during operation, and most electric wrenches are operated with one hand, and the control over the electric wrench is insufficient, resulting in inaccurate positioning and instability of the electric wrench. Utility Model Content

[0005] The purpose of this application is to provide an electric lever with improved efficiency, so as to improve the problem of injury to the operator and inconvenience in holding the lever firmly due to excessive torque.

[0006] The present application provides an electric switch for improving the use efficiency, which adopts the following technical solution:

[0007] An electric lever for improving use efficiency comprises a body shell, an outer surface of the body shell is fixedly sleeved with a stabilizing kit, a bottom end of the body shell is fixedly connected with a control panel, an outer surface of the lower end of the body shell is fixedly connected with a speed change switch, a fixing ring is fixedly installed inside the body shell, a motor is fixedly provided at one end of the fixing ring, a reducer is fixedly provided at one end of the motor, a fixing plate is fixedly provided at one end of the reducer, a safety clutch device is fixedly connected at one end of the fixing plate, a striking block is fixedly provided at one end of the safety clutch device, a counterweight is fixedly provided at one end of the striking block, a square shaft is fixedly connected at one end of the counterweight, a retaining spring is fixedly connected at one end of the square shaft, a rotating part is sleeved on the outer surface of the retaining spring, and the safety clutch device comprises a gear, a first half clutch is fixedly connected to the outer surface of one end of the gear, a second half clutch is meshedly connected to one end of the first half clutch, a spring is fixedly provided at one end of the second half clutch, a fixing plate is fixedly connected to one end of the spring, and a nut is fixedly connected to one end of the fixing plate.

[0008] By adopting the above technical scheme, the starting motor realizes the control of the output torque of the electric wrench, and the speed switch is pressed to start the motor. When the motor rotates, the output end drives the components in the reducer to reduce speed and increase torque, and then acts on the striking block. The striking block acts on the safety clutch device, and the resistance of the square shaft will compress the spring to operate backward, thereby driving the second half clutch to press and engage the first half clutch. When the transmission torque is overloaded, the axial separation between the toothed engaging grooves overcomes the elastic force of the spring, so that the second half clutch leaves the first half clutch. When the torque returns to normal, the first half clutch and the second half clutch are automatically combined again, thereby achieving the purpose of automatically preventing excessive torque safety protection. When the spring rebounds after the striking block passes through the square shaft, it pushes the striking block forward. At this time, the striking block will quickly hit the square shaft due to inertia, thereby achieving the purpose of protecting the electric wrench and the operator from injury while generating strong torque.

[0009] Optionally, the stabilization kit includes a fixing ring, a fixing block is fixedly connected to an outer surface of one side of the fixing ring, a fixing shaft is inserted through a middle portion of the fixing block, and handles are fixedly connected to outer surfaces of both ends of the fixing shaft.

[0010] By adopting the above technical solution, it is convenient for the operator to hold the switch firmly through the handle.

[0011] Optionally, the output end of the motor passes through the reducer, the fixed disk, the safety clutch device and the striking block respectively and is fixedly connected to the square shaft.

[0012] By adopting the above technical solution, the output end of the motor can drive the safety clutch device, the rotating part and the striking block at the same time.

[0013] Optionally, a battery pin is fixedly connected to the bottom end of the control board.

[0014] By adopting the above technical solution, the battery pins play a role in connecting and fixing the battery.

[0015] Optionally, outer surfaces at both ends of the housing are commonly connected with a blocking rod, and the blocking rod is in an "L" shape.

[0016] By adopting the above technical solution, the barrier rod can effectively protect the operator's hands from being hurt by foreign objects when the operator is operating.

[0017] Optionally, one end of the first half clutch and the second half clutch are both provided with tooth grooves for use with each other.

[0018] By adopting the above technical solution, the first half clutch and the second half clutch can achieve the purpose of separation and engagement through the toothed engagement groove under the condition of torque overload.

[0019] Optionally, a through circular groove is provided inside the square shaft.

[0020] The purpose of adopting the above technical solution is to facilitate the connection and installation of other connecting components.

[0021] Optionally, the handle is "U"-shaped, and the handle is located on one side of the upper portion of the housing.

[0022] By adopting the above technical solution, it is convenient for operators to further stabilize the handle when operating the electric switch, thereby improving the stability and portability of the operation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The utility model provides a safety clutch device so that the electric wrench can be automatically separated and engaged through the cooperation of the first half clutch and the second half clutch when it is started. When the torque is overloaded, the electric wrench stops rotating as the second half clutch is separated, thereby preventing the torque overload from causing harm to the operator, thereby improving the safety performance of the electric wrench.

[0025] 2. The utility model provides a stabilizing kit so that the operator can stabilize and reduce the shaking and deviation of the electric wrench caused by rotation by holding the handle while starting the electric wrench, and provides a baffle to effectively block external forces or foreign objects from the front, protecting the operator's hands from injury, thereby achieving a more stable and easy-to-carry effect.
