Abstract
The utility model relates to an electric hand drill accessory, in particular to a thread-free micro-force drill replacing fixing barrel, which consists of a drill handle, an inserting hole, an inner groove, a side groove, a locking plate, a locking rod, a sleeve, a rotating shaft, a chuck, an insertion strip, a pull ring, a top cap, a spring, a fixing strip and a rare earth magnet. The elliptic inserting hole is arranged on the upper end surface of the drill handle, and a cylindrical space is disposed inside the drill handle below the inserting hole. The locking plate is arranged at the bottom end of the locking rod and is an elliptic column. On a plane, projection of a center point of the cross section of a longitudinal groove on the side wall of the top cap is located on a long axis of the elliptic cross section of the locking plate. The thread-free micro-force drill replacing fixing barrel adopts a thread-free rotation locking method to realize longitudinal fixation of the drill handle, and is more labor-saving and faster compared with the prior art that a drill only can be fixed by means of applying large force via a wrench.
Description
Technical field
The utility model relates to a kind of electronic hand drill accessory, particularly relates to the little power drill bit of a kind of no screw thread and replaces stationary magazine creel.
Background technology
The pedestal of existing electronic hand drill, normally fix bit sub by three fan-shaped structures, fixedly the time, it is earlier tentatively fixing with bit sub that twisting earlier is placed in three sheath bodies on the fan-shaped structure, adopt spanner the pedestal of bit sub and electronic hand drill could be fixed again with very big power, but in the process that drill bit runs up, because the high-frequency vibration of himself still is easy to the phenomenon of skidding between bit sub and the pedestal.Therefore, exist the inconvenient and unstable drawback of installation of installation in the technical field that existing bit sub is fixed simultaneously.
The utility model content
The utility model is for solving the deficiencies in the prior art, provide a kind of can install easily the little power drill bit replacement of no screw thread stationary magazine creel that drill bit and pedestal are fixedly secured.
The scheme that solves the utility model technical problem is: the little power drill bit of no screw thread is replaced stationary magazine creel and is made of bit sub, jack, inside groove, side channel, locking plate, securing rod, sleeve, rotating shaft, chuck, filler rod, draw ring, top cover, spring, fixed strip and rare-earth magnet.
Bit sub is cylindrical, the lower end of bit sub is a drill bit, and there is an oval-shaped jack upper surface of bit sub, and there is an inside groove inside of the bit sub of jack below, inside groove is and the cylindrical space of bit sub concentric, a side channel is longitudinally arranged on the sidewall of bit sub.
Sleeve is the cylindrical shape that the lower end opens wide, the middle part of sleeve have one with sleeve be holistic annulus, the top of sleeve has a through hole, and a fixed strip is longitudinally arranged on the madial wall of sleeve lower end.One longitudinal fluting is arranged on the sidewall of the upper end of sleeve, a filler rod bar shaped, steel is arranged in the groove, the lower end of filler rod is placed in the rotating shaft and becomes rotation relation movingly with rotating shaft, and the outside, upper end of filler rod has one to be holistic semiorbicular draw ring with filler rod.Rotating shaft is positioned at the lower end of longitudinal fluting of described sleeve and as a whole with sleeve.
Securing rod is cylindrical, and securing rod is in the sleeve, and there is a locking plate bottom of securing rod, and locking plate is to be the cylindroid of integral body and concentric with securing rod.Locking plate is positioned at the following space of annulus of sleeve.Stretch out and fixing as a whole with discoidal top cover from the through hole at sleeve top on the top of securing rod.One cannelure identical with longitudinal fluting width, the shape of sleeve arranged on the sidewall of top cover, and the inner end of groove is inlaid with a rare-earth magnet.The upper end of filler rod is in the cannelure of top cover sidewall.
Have on the annulus in the sleeve and the sidewall of the securing rod in the space between the sleeve top with securing rod be holistic, discoidal chuck, the madial wall of chuck and sleeve is in active relationship.Between the annulus spring that is placed on the securing rod is arranged in chuck and the sleeve.
Bit sub is in the sleeve lower end and becomes assembling relation movingly with sleeve, and fixed strip is in the side channel and with side channel and becomes assembling to concern movingly.
The shape of locking plate and jack is coincide and can be passed through from jack.
The upper end of top cover and the rotating shaft of electronic hand drill are fixing as a whole.
In the plane, the projection of the central point of the cross section of fixed strip and filler rod all drops on same the diameter line of sleeve cross circular section, and in the plane, the projection of the central point of the cannelure cross section of the sidewall of top cover drops on the cross section long axis of ellipse of locking plate.
When needing drill bit is installed, earlier side channel is alignd with fixed strip and again bit sub is filled in the lower end of sleeve, again filler rod is screwed out from the cannelure of top cover sidewall, the transverse direction of the cross section of rotating cap locking plate is consistent with the transverse direction of the cross section of jack again, with top cover to pressing down, make locking plate enter behind the inside groove spin locking bar again, make the transverse of cross section of locking plate vertical with the transverse of the cross section of jack.At last the filler rod upper end is screwed in the cannelure of top cover sidewall again, bit sub promptly is fixed.
Adopt such scheme, can reach following remarkable technique effect:
Because the utility model is realized bit sub horizontal fix with side channel and filler rod with simple cooperation of the longitudinal fluting of sleeve by fixed strip, adopted the method for no screw thread rotation locking to realize that bit sub is fixing longitudinally simultaneously, could realize energetically that with existing must applying the fixing technology of drill bit compares by spanner, more laborsaving quick, simultaneously, because the double fixed of filler rod and fixed strip is arranged, the crosswise fixed of bit sub is more solid and reliable, and the situation of having avoided skidding in the prior art takes place.
