Specifically, since the latch 20 is movably disposed in the housing 10. In this way, the movement of the center positions of the first and second through holes 201 and 202 can be achieved by moving the cartridge 20. When the head 50 needs to be removed, the center position of the first through hole 201 is pushed to the center position of the head 50 by pushing the latch 20. Since the outer diameter of the first through hole 201 is larger than the outer diameter of the head 50. In this way, the batch head 50 can be removed from the first through hole 201. And when the head 50 is required to be mounted, the center position of the second through hole 202 is pushed to the center position of the head 50 by moving the cartridge 20. Since the outer diameter of the second through hole 202 is smaller than the outer diameter of the head 50, the outer diameter of the second through hole 202 is adapted to the diameter of the annular groove 501 on the head 50. In this way, the second through hole 202 and the annular groove 501 can be tightly attached to each other, so that the screwdriver bit 50 can be clamped and fixed. In this manner, quick replacement of the batch head 50 may be achieved.
According to the replacing structure of the screwdriver bit 50, the clamping block 20 is provided with the first through hole 201 and the second through hole 202, the first through hole 201 and the second through hole 202 are partially communicated, the diameter of the first through hole 201 is larger than that of the second through hole 202, and the clamping block 20 is movably arranged in the shell 10; the outer diameter of the batch head 50 is smaller than the diameter of the first through hole 201, the batch head 50 is provided with an annular groove 501 matched with the second through hole 202, the annular groove 501 is arranged in the second through hole 202 to lock and fix the batch head 50, and the batch head 50 is taken out from the first through hole 201 when the batch head 50 is replaced. Thus, the batch head 50 can be replaced quickly, and the batch head 50 can be replaced more conveniently.
The housing 10 includes: an upper housing 101 and a lower housing 102, wherein a fixture block groove 1011 is arranged on the upper housing 101, and the fixture block 20 is movably arranged in the fixture block groove 1011; as shown in fig. 2, the upper housing 101 is provided with a clamping groove 1011, and the size of the clamping groove 1011 is adapted to the clamping block 20. Thus, the clamping block 20 can move along the clamping block groove 1011, so that the positions of the first through hole 201 and the second through hole 202 can be simultaneously moved, and the batch head 50 is released after being clamped.
The lower casing 102 is fixedly connected with the upper casing 101, the upper casing 101 is provided with a third through hole 1013 and the lower casing 102 is provided with a fourth through hole 1021, and the batch head 50 is arranged in the fourth through hole 1021 and is clamped and fixed by the second through hole 202.

The transmission assembly can move to the end of the batch head 50 through the fourth through hole 1021 to drive the batch head 50 to rotate.
Referring to fig. 2 and 4, a return spring 40 is disposed at one end of the clamping block 20, a spring groove 1012 is further disposed at a position of the upper housing 101 corresponding to the return spring 40, and the return spring 40 is disposed in the spring groove 1012 to provide a pushing force for the clamping block 20, so as to push the second through hole 202 on the clamping block 20 to a position around the annular groove 501 of the batch head 50. The return spring 40 may be mounted by the spring groove 1012. After the annular groove 501 of the head 50 is inserted into the first through hole 201, the return spring 40 may provide a certain pushing force to the latch 20, so as to clamp the head 50.
Referring to fig. 3, a stopper 204 is further disposed on an upper surface of the one end of the clamping block 20, and the stopper 204 is configured to abut against the spring groove 1012 to limit the displacement of the clamping block 20. The stopper 204 can clamp the buckle. After the screwdriver 50 is detached, the screwdriver 50 may slide out of the clamping groove 1011 due to the loss of the blocking of the screwdriver 50 by the clamping block 20, so as to prevent the clamping block 20 from sliding out of the clamping groove 1011, and the displacement of the clamping block 20 is limited by the abutment against the spring groove 1012, so as to prevent the clamping block 20 from sliding out of the clamping groove 1011 and prevent the clamping block 20 from falling.
