As shown in fig. 1, 2, 3, and 4, an electric screwdriver includes: the screwdriver comprises a rotating seat 100, a screwdriver head 200, a clamping ball 300, a clamping elastic sheet 400 and a handle 500, wherein the screwdriver head 200 is detachably fixed on the rotating seat 100 in a clamping mode between the clamping ball 300 and a ball groove 210, so that the problem that the screwdriver head 200 is easy to drop when a user uses the screwdriver is avoided.
The batch head 200 is a head of a screwdriver, the batch head 200 is movably connected with the rotary base 100, the batch head 200 is provided with a ball groove 210, in practical use, different batch heads 200 can be replaced by the screwdriver in order to be suitable for different screws, and in the embodiment, the batch heads 200 for replacing the screwdriver are provided with the ball grooves 210.
The shape of the clamping ball 300 is matched with that of the ball groove 210, and the clamping ball 300 is movably arranged in the radial mounting hole 120.
The clamping spring plate 400 is arranged on the rotating seat 100, the clamping spring plate 400 is abutted against the clamping ball 300 and connected with the clamping ball 300, and the clamping spring plate 400 can push the clamping ball 300 to move towards the axial mounting hole 110 and enable the clamping ball 300 to be embedded into the ball groove 210.
In the actual manufacturing process, can set up the shell fragment mounting groove of being convenient for install joint shell fragment 400 at rotation seat 100, install joint shell fragment 400 in the shell fragment mounting groove, the shape of shell fragment mounting groove and the shape looks adaptation of joint shell fragment 400, the purpose that sets up the shell fragment mounting groove is the removal of restriction joint shell fragment 400, has also reduced the volume that rotates seat 100.
Particularly, when pushing the batch head 200 to move towards the axial mounting hole 110, the batch head 200 will gradually abut against and be connected with the clamping ball 300, and at this time, the batch head 200 will be pushed to move towards the axial mounting hole 110, the batch head 200 will push the clamping ball 300 to move towards the direction of the clamping elastic sheet 400 until the clamping ball 300 is completely pushed into the radial mounting hole 120, and the clamping elastic sheet 400 will also be extruded by the clamping ball 300 to deform.
At this time, the batch head 200 is continuously pushed to move towards the axial mounting hole 110 until the clamping ball 300 and the ball groove 210 start to be abutted and connected, because of the elasticity of the clamping elastic sheet 400, the clamping elastic sheet 400 tends to reset, at this time, the batch head 200 is continuously pushed to move towards the axial mounting hole 110, the clamping elastic sheet 400 can push the clamping ball 300 to move towards the axial mounting hole 110 until the clamping ball 300 and the ball groove 210 are completely matched, and the clamping ball 300 completes locking of the batch head 200.
Correspondingly, when the batch head 200 needs to be dismounted, the batch head 200 is pulled to move outwards, the batch head 200 can push the clamping ball 300 to move towards the direction of the clamping elastic sheet 400 until the clamping ball 300 is completely pushed into the radial mounting hole 120, the clamping ball 300 unlocks the batch head 200, and the clamping elastic sheet 400 is also extruded by the clamping ball 300 to deform.
At this moment, the batch head 200 continues to be pulled to move outwards, and due to the elasticity of the clamping elastic sheet 400, the clamping elastic sheet 400 tends to reset, and at this moment, the batch head 200 continues to be pulled to move outwards, and the clamping elastic sheet 400 pushes the clamping ball 300 to move towards the axial mounting hole 110 until the clamping elastic sheet 400 recovers, and the clamping ball 300 stops moving.
The handle 500 and the rotatable base 100 are actually rotatably mounted in the handle 500, so that the bit 200 can be rotated relative to the handle 500.
It should be particularly noted that, in the prior art, in order to be suitable for different screws, a screwdriver needs to replace different bits 200, and in order to facilitate replacement of the bits 200, the bits 200 of the screwdriver and the handle 500 are simply plugged together, which has a problem that the bits 200 are easy to fall off during use.
Therefore, in the above embodiment, the rapid clamping of the batch head 200 can be completed by combining the clamping spring 400 and the clamping ball 300, the user only needs to slowly insert the required batch head 200 into the rotary base 100, and the clamping ball 300 can automatically cooperate with the ball groove 210 to complete the clamping locking after the batch head 200 is pushed to the bottom, so that the batch head 200 is not easy to fall off.

Preferably, when joint ball 300 is located during the first station, joint ball 300 imbeds ball groove 210, when joint ball 300 is located during the second station, joint ball 300 with ball groove 210 separates, because joint shell fragment 400 is contradicted with joint ball 300 and is connected, promotes joint ball 300 and removes certain power that need overcome from first station towards the second station to make and push into batch head 200 and take out the in-process of batch head 200 and all need certain power, consequently batch head 200 is difficult to drop easily.
Specifically, when the batch head 200 is pushed to move towards the axial mounting hole 110, the batch head 200 will gradually abut against the clamping ball 300 to be connected, at this time, the batch head 200 is continuously pushed to move towards the axial mounting hole 110, the batch head 200 will push the clamping ball 300 to move towards the second station direction until the clamping ball 300 is separated from the ball groove 210, and the clamping spring piece 400 is also squeezed by the clamping ball 300 to deform.
At this time, the batch head 200 is continuously pushed to move towards the axial mounting hole 110 until the clamping ball 300 and the ball groove 210 start to be abutted and connected, because of the elasticity of the clamping elastic sheet 400, the clamping elastic sheet 400 tends to reset, at this time, the batch head 200 is continuously pushed to move towards the axial mounting hole 110, the clamping elastic sheet 400 can push the clamping ball 300 to return to the first station, and the clamping ball 300 completes locking the batch head 200.
Correspondingly, when the batch head 200 needs to be dismounted, the batch head 200 is pulled to move outwards, the batch head 200 can push the clamping ball 300 to move towards the direction of the second station until the clamping ball 300 is completely pushed to the second station, the clamping ball 300 unlocks the batch head 200, and the clamping elastic piece 400 is also extruded by the clamping ball 300 to deform.
At this moment, continue to stimulate batch head 200 and move outwards, because the elasticity that joint shell fragment 400 self has, joint shell fragment 400 has the trend that resets, continues to stimulate batch head 200 and moves outwards this moment, and joint shell fragment 400 can push joint ball 300 and return to first station to joint shell fragment 400 recovers.
