Abstract

The utility model discloses a can deposit electric hand drill handle of boring key, the internal diameter of the hollow body of handle is greater than the external diameter of the key body, and hollow length is enough to make key body and key pole put into it, is equipped with the lid in hollow body's outer end. The key rod is put into the containing hole of the key body. The outer end of the hollow body is provided with a thread and a nut matched with the thread. A neodymium magnet is arranged in the screw cap. The drill key is fixedly arranged in the hollow body of the handle, so that the key is not easy to lose and the use is convenient.

Description

A kind of electric hand drill handle that bores key of depositing

The utility model relates to a kind of electric hand drill handle, especially a kind of electric hand drill handle that makes it be difficult for losing that bores key of depositing.

Present electric hand drill mainly comprises brill key, drill chuck and handle etc., 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 utilize 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 handle that bores key of depositing, and it will bore the ducted body inside that key is placed on handle regularly, make key be difficult for losing, and will be easy to use.

The purpose of this utility model is achieved in that a kind of electric hand drill handle that bores key of depositing, and the internal diameter of handle ducted body is greater than the external diameter of key body, and the length of ducted body is enough to make key body and key bar to put into it, is provided with lid in the outer end of ducted body.

Key bar is placed in the containing hole of key body.

Outer end at ducted body is provided with screw thread, and has nut to cooperate with it.

Neodium magnet is set in nut.

The outer end of ducted body and the connected mode of lid are the connected mode of groove and slide plate or the connected mode of draw-in groove and projection.

The preceding part of handle ducted body is just in time put into the afterbody of key body, and the back part of handle ducted body just in time will be bored the head of key and be put into.

The utility model is difficult for losing owing to bore the ducted body inside that key is placed on handle regularly, and is easy to use; Because the appearance and size of handle does not change, so overall structure is constant, the technology applicability is strong.

Describe in detail according to a kind of concrete structure and the operation principle of depositing the electric hand drill handle that bores key 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.

It is a ducted body that the utility model can be deposited the electric hand drill handle 4 that bores key, 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 have nut 5 to cooperate with it, as shown in Figure 3.

In order to make the space in the handle can hold the brill key, correspondingly will bore key improves, bore key and comprise key body 2 and key bar 1, as shown in Figure 1, the bigger formation plug 11 of key bar 1 one ends bores key body 2 and is provided with conical tooth 21, can cooperate with the tooth on the drill chuck, be provided with the through hole 22 with key body 2 axis normal at the rear portion of key body 2, the external diameter of through hole 22 is greater than the external diameter of key bar 1 one ends, 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 that neodium magnet is pasted in it.

Because the handle of present electric hand drill, majority is a hollow, and the afterbody of handle does not have capping, and the utility model improves the internal structure of handle under the situation of the appearance and size that does not change handle, and increase by a nut at the afterbody of handle, novel split type brill key is put into wherein, made the brill key be difficult for losing, bring great convenience to the user, in order to make key be unlikely in handle, to rock, the preceding part of handle ducted body is thinner, and is slightly thicker than the key body afterbody of novel brill key, just in time the afterbody of key body put into, and the back part of handle ducted body is thicker, slightly thicker than the head that bores key, just in time will bore the head of key to put into, after putting into, because thickness difference before and after the ducted body of handle, bore key and be fixed on just in the handle, very stable, be difficult for rocking, at last, nut is screwed on, pushed down key bit, make it more stable, can in handle, not produce and rock, thereby not influence the normal use of electric hand drill.

At ordinary times, will bore in the ducted body of key insertion handle, and cover nut; 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 can make drill bit tightly fixing or unclamp, and will bore key after using up again and put back in the ducted body of handle.

An embodiment more of the present utility model can be provided with neodium magnet in nut 5, play fixation.

In addition, can be varied in the connected mode of the outer end of ducted body and lid, not only be confined to being connected of screw thread and nut, also can be the connected mode of groove and slide plate, or the connected mode of draw-in groove and projection, or the like.
