Background

The multi-head electric tool is a popular electric tool in the market, the tool main body is a power component, and the power component can work together with various working heads; the types of the hand-held impact wrench can be classified into hand-held gun drills, hand-held impact wrenches, hand-held electric impact shears, hand-held angle grinders, hand-held impact screwdrivers, hand-held polishing machines and the like. The current tool main body is provided with a motor and a control switch for driving the motor to rotate, and as the control switch has the same structure and usually does not have an identification function, the connecting structure of the different types of working heads connected with the tool main body is the same, and the different types of working heads can normally work by pressing the control switch when being arranged in the tool main body. Some work is unidirectional rotation, and some work heads need bidirectional rotation; when working heads of different types are installed in the tool main body, the working heads cannot be well identified; for example, when a work head capable of unidirectional rotation is mounted in a tool body, the control switch can drive the motor to rotate in the forward and reverse directions, which can cause damage to the work head. When some working heads need to rotate bidirectionally, the type of the motor on the tool main body is just a unidirectional motor; although the working head can be installed in the tool main body, the working head can only be driven to rotate in one direction; in the actual operation process, more inconvenience exists, more working environments cannot be adapted, and the universality is poor. It is therefore desirable to design a detachable power tool with identification to overcome the above difficulties.

When the driving piece rotates, the angle between the driving piece and the switch body changes, the switch body is a two-way switch of a conventional model, the left and right directions of the driving piece are different, and the rotation directions of the switch body control motor are different. In a default state, a boss on the deflector rod is positioned in the first concave part, at the moment, the deflector rod cannot be stirred, and the driving piece is positioned on the central axis of the switch body; when the driving rod is shifted to drive the driving piece to rotate, the driving piece deviates from the central axis of the switch body, and the guide part on the driving piece is aligned with the guide groove, so that the steering of the motor can be conveniently controlled.

The width of the clamping groove is the same as that of the identification key, and the clamping groove can limit the identification key left and right; the thickness of the clamping groove is the same as that of the identification key, and the clamping groove can limit the identification key up and down. Thus, the identification key can only move in the axial direction of the card slot.

Preferably, a second protrusion is arranged on the end face of the pushing part facing the identification key, and the second protrusion pushes the identification key to enable the boss to be located in the bidirectional limiting part when the working head is arranged in the shell.

The second bulge protrudes outwards towards the direction of the identification key, so that the stroke of the pushing part for pushing the identification key is increased; when the working head is locked by the locking device on the shell, the boss on the deflector rod is just positioned in the bidirectional limiting part, so that the deflector rod can be toggled bidirectionally. Therefore, the working head provided with the second protrusion is used in a bidirectional rotation working environment.

Preferably, the pushing part pushes the identification key to enable the boss to be in the one-way limiting part when the working head is installed in the shell. Therefore, when the working head is installed in the shell, the deflector rod can only be pulled in one direction, and the working head can only be used in a working environment with unidirectional rotation.

Compared with the prior art, the utility model has the following beneficial effects: the utility model is provided with a plurality of types of working heads which are detachably connected with the machine shell and the working heads are locked by a locking device; when the working heads of different types are matched with the machine shell, different working conditions are suitable, so that an electric tool carrying multiple signals at the same time is not needed, only the working heads of corresponding types are needed to be carried, and the electric tool is convenient to use and good in universality. An identification key for identifying the model of the working head is also arranged in the shell, and the stirring direction of the deflector rod is limited by the identification key. When working heads of different types are arranged in the shell, the strokes of the working heads for pushing the identification keys are different, so that the stirring ranges of the stirring rods are different; when the deflector rod moves, the driving piece is driven to rotate, the direction of the driving piece and the switch body is controlled by the position of the deflector rod, the switch body is a two-way switch, the direction of the driving piece is different from the direction of the motor controlled by the switch body, and therefore the motor can be conveniently controlled to turn through the switch assembly. Under the default state, the working head is not installed in the shell, the deflector rod is locked by the identification key, and the switch component is in a locking state at the moment, so that misoperation of the electric tool is avoided. Therefore, the utility model is convenient to detach, safe and reliable to use and good in universality.
