Specifically, the tool bit replacement assembly comprises a sleeve 10, wherein the inner wall of the sleeve 10 is step-shaped, and the sleeve 10 is cylindrical. It should be noted that the socket 10 is connected to one end of the external electric screwdriver housing 100 in a socket manner, and the socket 10 is configured to move a predetermined distance in a direction approaching the external electric screwdriver housing 100.
Specifically, the tool bit changing assembly further comprises a shaft rod 20, the shaft rod 20 is disposed in the socket 10 and is located at the center of the socket 10, and two ends of the shaft rod 20 are located outside the socket 10. It is worth mentioning that one end of the shaft 20 is rotatably connected to the external electric motor 300, and the other end of the shaft 20 is connected to the external cutter head.
It should be noted that, an end of the shaft 20 facing away from the external electric motor 300 has an insertion hole 201, and the insertion hole 201 is connected with the external tool bit, wherein the insertion hole 201 is connected with the external tool bit in a sliding manner.
Specifically, the cutter head replacement assembly further comprises a limiting member 30, the limiting member 30 is connected with an external cutter head in a sleeved manner, and the limiting member 30 is further connected with one end of the shaft rod 20, which is provided with an insertion hole 201, in a threaded manner. It should be noted that the limiting member 30 is configured to rotate a predetermined angle to clamp or loosen the external tool bit, in other words, when the limiting member 30 moves a predetermined distance in a direction approaching the shaft 20, the limiting member 30 clamps the external tool bit, so as to prevent the external tool bit from being separated from the insertion hole 201, and when the limiting member 30 moves a predetermined distance in a direction away from the shaft 20, the limiting member 30 loosens the external tool bit, so that the user can take out the external tool bit manually.
Further, a protrusion 21 is disposed on the periphery of the middle section of the shaft 20, and the cross-sectional shape of the protrusion 21 is rectangular.
Specifically, the cutter head replacement assembly further comprises a moving assembly 40, the moving assembly 40 is disposed in the sleeve 10, the moving assembly 40 is located on one side of the protrusion 21 close to the limiting member 30, wherein the moving assembly 40 is configured to move a predetermined distance in a direction close to the protrusion 21, so that the moving assembly 40 is connected to the protrusion 21 in a clamping manner, and further the rotation of the shaft rod 20 is limited, so that a user can manually rotate the limiting member 30 to take out an external cutter head.
Further, the moving assembly 40 includes a plate 41, two ends of the plate 41 are fixedly connected to the inner wall of the socket 10, the plate 41 has a through slot 4101, and the through slot 4101 faces the protrusion 21 of the shaft 20, wherein the socket 10 can be subjected to an external force to make the socket 10 move to a predetermined distance in a direction approaching the external electric screwdriver housing 100, and the plate 41 moves to a predetermined distance in a direction approaching the protrusion 21 to make the protrusion 21 be disposed in the through slot 4101, it is worth mentioning that the size of the through slot 4101 is identical to the size of the protrusion 21, in other words, the shape of the through slot 4101 is rectangular, when the protrusion 21 is disposed in the through slot 4101, the plate 41 limits the rotation of the shaft 20, in contrast to when the socket 10 moves to a direction away from the external electric screwdriver housing 100, the projection 21 is disengaged from the through slot 4101, at which point the plate 41 no longer restricts the rotation of the shaft 20. It should be noted that, when the plate 41 no longer limits the rotation of the shaft 20, the limiting member 30 will rotate along with the shaft 20, and at this time, the user cannot replace the external tool bit, and when the plate 41 limits the rotation of the shaft 20, the user can manually rotate the limiting member 30, so as to replace the external tool bit.
In order to facilitate the resetting of the socket 10, the present invention is further improved, and further, as shown in fig. 2 to 4, the moving assembly 40 further includes two oppositely disposed elastic members 42, one end of each of the two elastic members 42 is fixedly connected to one side of the plate 41 close to the protrusion 21, and the other end of each of the two elastic members 42 abuts against the inner wall of the external electric screwdriver shell 100. It should be noted that, when the socket 10 receives an external force and moves toward the direction approaching the external electric screwdriver shell 100, the plate 41 moves a predetermined distance toward the protrusion 21, and the elastic member 42 is pressed by the plate 41 to deform, and when the socket 10 does not receive an external force, the plate 41 receives a thrust of the elastic member 42, so that the plate 41 moves a predetermined distance away from the protrusion 21, and the socket 10 moves a predetermined distance along with the plate 41.
In conclusion, the tool bit replacing assembly for the electric screwdriver based on the embodiment of the application is clarified, and the tool bit replacing assembly for the electric screwdriver provides the advantages of quick tool bit replacement, convenience in disassembly and assembly, convenience in use and the like.
