[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Figures 1 to 3 A screwdriver 100 in one embodiment is shown, which includes a screwdriver body 10 and an end cap 20, wherein the end cap 20 is detachably connected to one end of the screwdriver body 10, so that the screwdriver 100 is cylindrical as a whole. The screwdriver body 10 is cylindrical as a whole, and an output shaft 12 extends from its first end 11. In this embodiment, the screwdriver 100 is an electric screwdriver, and the output shaft 12 can rotate around its own rotation axis under the drive of a driving device inside the screwdriver 100. In one embodiment, a receiving hole 13 is provided at the end of the output shaft 12 facing the end cap 20, and the receiving hole 13 can accommodate a screwdriver bit 30, so that the screwdriver bit 30 can rotate synchronously with the output shaft 12.

[0027] In this embodiment, the end cap 20 is hollow and has a closed end 21 and an open end 22 opposite to each other. The end cap 20 is detachably connected to the first end 11 and accommodates the output shaft 12 therein. The end cap 20 includes a plurality of screwdriver bit storage portions 23 (see Figure 4 and Figure 5 ), when the end cover 20 is connected to the first end 11 , the plurality of bit receiving portions 23 surround the output shaft 12 .

[0028] With such a structure, the screwdriver 100 can accommodate several screw bits 30 without using an additional storage box, and the screwdriver 100 and the screw bits 30 occupy less space and are easy to carry. For users who only need a few types of screw bits, it is easy to find the screw bits they need from the end cover 20.

[0029] refer to Figures 4 to 6In one embodiment, the end cap 20 includes an outer shell 24 and an inner shell 25 received in and fixed to the outer shell 24. The outer shell 24 and the inner shell 25 are both cylinders with one end open. The closed end 251 of the inner shell 25 faces the closed end 241 of the outer shell 24, and the end surface 252 of the closed end 251 away from the closed end 241 of the outer shell 24 extends with a plurality of protrusions 253 around the axis L of the end cap 20, and the protrusions 253 are provided with receiving holes 254, and each receiving hole 254 is used to receive a screwdriver bit 30. In other words, the plurality of screwdriver bit storage portions 23 are the plurality of receiving holes 254.

[0030] In one embodiment, the end cap 20 includes a connecting shaft 26 extending from the closed end 21 to the open end 22, and the end of the connecting shaft 26 is received in the receiving hole 13 of the output shaft 12, so that the end cap 20 is detachably connected to the screwdriver body 10. In one embodiment, the cross-section of the receiving hole 13 and the connecting shaft 26 is non-circular, for example, both are regular hexagons. In this way, the end cap 20 will not rotate relative to the output shaft 12.

[0031] In one embodiment, the connecting shaft 26 and the output shaft 13 are detachably connected together by magnetic attraction. For example, one of the connecting shaft 26 and the output shaft 13 is a magnet, and the other is made of a material that can be attracted by a magnet.

[0032] refer to Figure 4 , Figure 7 and Figure 8 In one embodiment, the end cap 20 includes a magnet 27 disposed at one end near each bit storage portion 23, and the magnet 27 is used to absorb the bit 30 accommodated in the bit storage portion 23. In this embodiment, the end surface 255 of the closed end 251 facing the closed end 241 of the housing 24 is provided with a plurality of receiving holes 256 corresponding to the receiving holes 254 of the protrusion 253, each receiving hole 256 accommodates a magnet 27, and each receiving hole 256 is connected to its corresponding receiving hole 254, so that one end of the bit 30 accommodated in the receiving hole 254 can contact the magnet 27 in the receiving hole 256, and then the bit 30 can be attracted by the magnet 27 and retained in the receiving hole 254.

[0033] In one embodiment, the connecting shaft 12 is rotatably connected to the inner shell 25. The connecting shaft 12 extends along the axis L of the end cap 20. In this embodiment, the inner shell 25 includes a through hole 258 surrounded by the plurality of protrusions 253, and the through hole 258 accommodates a sleeve 259. The connecting shaft 12 passes through the inner ring of the sleeve 259 and is rotatably connected to the inner shell 25 through the sleeve 259. With such a configuration, the user can apply an external force to the end cap 20 to rotate it relative to the connecting shaft 12. Since the connecting shaft 12 cannot rotate relative to the output shaft 12, the ability of the end cap 20 to rotate relative to the connecting shaft 12 means that the end cap 20 can rotate relative to the screwdriver body 10.

[0034] In one embodiment, a locking member 40 is fixed in the inner shell 25, and a locking member matching portion 41 is fixed on the connecting shaft 12. The locking member 40 and the locking member matching portion 41 are engaged with each other, thereby preventing the end cap 20 from rotating relative to the connecting shaft 12. With such a structure, the end cap 20 will not rotate relative to the connecting shaft 12 without the external force from the user.

[0035] In one embodiment, the locking member mating portion 41 is a gear ring sleeved on the connecting shaft 12, and a plurality of meshing teeth 411 are evenly arranged on the circumferential outer surface of the gear ring. In one embodiment, the locking member 40 includes a spring 401 and a block 402, and the two ends of the spring 401 are respectively in contact with the inner shell 25 and the block 402, and the block 402 includes one or more tooth grooves 403, and the one or more tooth grooves 403 are meshed with one or more meshing teeth 411 of the gear ring 41, thereby preventing the end cap 20 from rotating relative to the connecting shaft 12. With such a structure, when no external force of the user acts on the end cap 20, the elastic thrust of the spring 401 keeps the meshing teeth 411 and the tooth grooves 403 tightly meshed, and the end cap 20 will remain stationary relative to the screwdriver body 10. When the external force applied by the user to the end cap 20 is able to overcome the elastic thrust of the spring 401, the meshing teeth 411 received in the tooth groove 40 gradually move out of the tooth groove 403 until a new set of meshing teeth 411 moves into the tooth groove 40. In the process of the user rotating the end cap 20, the relative movement between the meshing teeth 411 and the tooth groove 403 will occur repeatedly. Through the above structure, the user can sense the rotation of the end cap 20 relative to the screwdriver body 10, and the above structure can provide the user with a sense of gear, that is, the user can roughly sense the rotation angle of the end cap 20 relative to the screwdriver body 10 through the meshing teeth 411 moving into and out of the tooth groove 403.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
