Abstract
The utility model discloses a key is bored to electric hand drill that can deposit, including the key body and key pole, the key body and key pole are the separation, but key pole holding is internal at the key. The key body is provided with a through hole perpendicular to the axis of the key body at the rear part, the inner diameter of the through hole is larger than the outer diameter of the key rod and smaller than the outer size of the plug, a containing hole is arranged in the key body along the axis direction, the inner diameter of the containing hole is larger than the outer diameter of the key rod, and the key rod can be inserted into the containing hole. It is fixedly arranged in the hollow body of the handle, is not easy to lose and is convenient to use.
Description
The utility model relates to a kind of brill key, and especially a kind of electric hand drill that is difficult for losing is with boring key.
Present electric hand drill drill chuck is provided with the tooth that can cooperate with the key body conical tooth, for drill bit is fixing tight or unclamp, thereby normally utilizes the tooth of the conical tooth of key body and drill chuck to be rotatably assorted to make drill bit to be fixed or unclamp.Bore key and generally comprise key body and key bar, the two is an one, no matter be homemade, or the electric hand drill of import, impact electric hand drill, its key all separates with electric hand drill, in use be very easy to lose, after the key loss, can only pound tight or unclamp, both easily drill chuck be smashed like that with harder metal devices such as screwdriver and hand hammers, also be not easy drill chuck is locked, cause very big trouble to the user.
The purpose of this utility model provides a kind of electric hand drill of depositing and bores key, and it is placed on the ducted body inside of handle regularly, is difficult for losing, and is easy to use.
The purpose of this utility model is achieved in that a kind of electric hand drill of depositing bores key, comprises key body and key bar, and key body separates with key bar, and key bar can be contained in the key body.
The bigger formation plug of key bar one end.
Be provided with the through hole with the key body axis normal at the rear portion of key body, the internal diameter of through hole is greater than the external diameter of key bar, and less than the external dimensions of plug; Key body inside is provided with containing hole along axis direction, and the internal diameter of containing hole is greater than the external diameter of key bar, and key bar can insert in the containing hole.
Bottom at containing hole is provided with magnet.
Adopt epoxide-resin glue or seccotine that neodium magnet is pasted in it.
The utility model is difficult for losing because the drill bit key is placed on the ducted body inside of handle regularly, and is easy to use; Because the appearance and size of handle does not change, so the drill bit overall structure is constant, the technology applicability is strong; Owing on key body, be provided with hole in length and breadth, make it both can satisfy instructions for use, can when not using, reduce volume again; Owing in the containing hole of key body, be provided with magnet, key bar can be held securely, do not influence the use of electric hand drill.
Describe the concrete structure and the operation principle of boring key in detail according to a kind of electric hand drill of depositing that the utility model proposes below in conjunction with accompanying drawing.
Fig. 1 bores key outward appearance front view in use for the utility model;
Fig. 2 is positioned at the cutaway view of key body for key bar of the present utility model;
Fig. 3 is positioned at the cutaway view of handle for brill key of the present utility model.
The electric hand drill that the utility model can be deposited bores key, mainly comprise key body 2 and key bar 1, as shown in Figure 1, the bigger formation plug 11 of key bar 1 one ends, bore key body 2 and be provided with conical tooth 21, can cooperate, be provided with through hole 22 at the rear portion of key body 2 with key body 2 axis normal with the tooth on the drill chuck, the internal diameter of through hole 22 is slightly larger than the external diameter of key bar 1, and less than the external dimensions of plug 11; In addition, key body 2 inside are provided with containing hole 23 along axis direction, and the internal diameter of containing hole 23 is slightly larger than the external diameter of key bar 1, as shown in Figure 2, are provided with magnet 3 in the bottom of containing hole 23, can adopt epoxide-resin glue or other seccotines that neodium magnet is pasted in it;
The handle 4 of the utility model electric hand drill is a ducted body, and the internal diameter of ducted body is greater than the external diameter of key body, and the length of ducted body is enough to make the brill key to put into it, is provided with screw thread 41 in the outer end of ducted body, and has nut 5 to cooperate with it, as shown in Figure 3.
At ordinary times, key bar is placed in the containing hole of key body, will bore in the ducted body of key insertion handle, and cover nut, makes the brill key not leave the electric hand drill main body, therefore can not lose; During use, open nut, key is taken out, from containing hole, extract key bar, in then that key bar insertion and key body is the axially vertical through hole, can form one and bore key, the tooth of the conical tooth of key body and drill chuck is rotatably assorted makes drill chuck fixing tight or unclamp, to bore key after using up again and put back in the ducted body of handle, and, therefore can not influence the use of electric hand drill in handle because it is fixed.
Another embodiment of the present utility model is not provided with neodium magnet and can yet in containing hole.
