Description
Technical field
The utility model belongs to drilling attachment in a kind of hardware ＆ tools, and in particular to a kind of from impact drill chuck.
Background technology
The domestic patents of the applicant early stage application two（Application number is respectively 201620776745.1 Hes
201620776788.X）, all refer to from impact drill chuck, the technical scheme of use be overcoat front end internal impact block it is raised with
Groove is raised with the end face Impactor of nut sleeve and groove links together, and has spring to connect between bonnet and drill body, spring branch
Support bonnet, the movement that bonnet compression spring can be axial.Operation principle is：When installing and using, the connecting rod at drill body rear portion with it is dynamic
The power transmission shaft connection of power equipment, drives drill body to drive three-jaw and folded instrument synchronous axial system during drive axis.Hold with a hand outer
Set, electric drill is rotated forward, and drill body and clamping jaw follow rotation, and overcoat and screw are not rotated relative to drill body, and the screw thread of clamping jaw is along screw
Screw thread rotation is closed, and after clamping jaw clamping tool, screw, nut sleeve, clamping jaw and drill body are rotated together, and overcoat is motionless, in overcoat
The raised raised impact of Impactor by nut sleeve of impact block, there is inclined-plane the side of two projections, and the impact block of overcoat is convex
Rising can move axially the Impactor for crossing nut sleeve projection, and spring is compressed, and after crossing projection, the pulling force by spring enters again
Enter the groove of nut sleeve, carry out subsequent cycle, often clash into, give screw one rotary torsion, screw screw thread promotes clamping jaw folder
Clamping tool.But the above-mentioned clamping torque from impact drill chuck is small, when particularly on high intensity and powerful electric drill, folder
Clamp force square is substantially less than normal；In addition when chuck unclamps, electric drill is reversely rotated, and is unclamped by auto impact, but sometimes because of impulsive force
It is too small that the phenomenon that pine does not hold can occur.
The content of the invention
For above technological deficiency, the utility model makes improvement to above-mentioned from impact drill chuck, solves this kind of from impact
The small problem of the clamping torque of chuck.
The technical solution adopted in the utility model is：It is a kind of from impact drill chuck, including drill body, overcoat, screw, clamping jaw,
Nut sleeve, spring, bonnet and jump ring, three clamping jaws are separately mounted in three decile inclined holes of drill body, and screw is arranged on drill body
Screw groove in, the screw thread of screw and clamping jaw forms thread transmission, and nut sleeve is fixedly connected with screw, inside overcoat front end
Impact block is raised and groove is docking together with the facing groove and Impactor projection of nut sleeve, and two projections are provided with inclined-plane,
Overcoat and nut sleeve form gap and coordinate, and overcoat back end inner circumference sets a jump-ring slot, and interporal lacuna coordinates in bonnet and overcoat, quilt
Jump ring is blocked, and has spring to connect between bonnet and drill body, after be stamped through hole and be enclosed within drill body, spring supporting bonnet, bonnet compression
Spring can axial direction movement, jump ring is stuck in the groove of overcoat, and the head end of drill body is provided with driving hole, the head end excircle of overcoat
Cone tooth with taper is set, is inserted in the driving hole of drill body using drill chuck wrench, the outer cone tooth for putting can be driven.
Preferably, driving hole averagely sets 1-3 around drill body.
The utility model can also be screwed further outer using drill chuck wrench after auto impact clamping to clamping direction
Set, increases clamping collet torque, particularly for high intensity or high-power electric drill.During release, if because of impulsive force too little Song
Do not open chuck, it is possible to use drill chuck wrench reversely rotates overcoat, unclamp the instruments such as drill bit.

Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings, as shown in figure 1, it is existing from
Impact drill chuck includes drill body 1, overcoat 2, screw 3, clamping jaw 4, nut sleeve 5, spring 6, bonnet 7 and jump ring 8, three 4 points of clamping jaws
An Zhuan not be in three decile inclined holes of drill body 1, screw 3 is arranged in the screw groove of drill body 1, the screw thread shape of screw 3 and clamping jaw 4
Into thread transmission, nut sleeve 5 is fixedly connected with screw 3, and the front end of overcoat 2 inside sets impact block raised 21 and is provided with groove
A22, the end face of screw 5 sets groove B52 and Impactor projection 51, impact block projection 21 and groove A22 and screw on overcoat 2
Groove B52 and Impactor projection 51 on set 5 can be docking together, and two projections are provided with inclined-plane, such overcoat and screw
Set can form gap cooperation, and the back end inner circumference of overcoat 2 sets a jump-ring slot, and interporal lacuna coordinates in bonnet 7 and overcoat 2, by card
Spring 8 is blocked, and has spring 6 to connect between bonnet 7 and drill body 1, and bonnet 7 has through hole to be enclosed within drill body 1, the supporting rear cover 7 of spring 6, after
The compression spring 6 of lid 7 can be moved axially, and jump ring 8 is stuck in the groove of overcoat 2, and this kind of operation principle from impact drill chuck exists
Had been introduced in background technology, will not be described here.
As shown in Figure 2,3, the utility model makes improvement on the basis of the above-mentioned drill chuck from impact, in the head of drill body 1
End is provided with driving hole 10, and the head end excircle of overcoat 2 sets the cone tooth 23 with taper, drill body is inserted using drill chuck wrench 9
In driving hole, the outer cone tooth 23 for putting can be driven.When in use, further screwed outward to clamping direction using drill chuck wrench
Set, because overcoat 2 has been fixed by drill chuck wrench 9 in the axial direction, therefore on impact block on overcoat 2 raised 21 and nut sleeve 5
Impactor raised 51 when contacting, the impact block projection 21 of overcoat cannot move axially cross nut sleeve 5 Impactor it is raised
51, therefore can not open the situation of chuck with the further increase chuck torque of turn drill chuck wrench 9 or in impulsive force too little Song
Lower release chuck.
Further, driving hole 10 averagely sets 1-3 around drill body.
The utility model is provided with cone tooth in the head end from the basis of impact drill chuck in overcoat, and drill chuck wrench insertion is bored
In body driving hole, the outer cone tooth for putting can be driven, be to from the useful supplement from impact function for impacting drill chuck, its structure is simple
Single reasonable, input torque is big, easy for operation, is a kind of preferable auto impact and wrench multifunctional drill chuck.
The foregoing is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of this area
For member, on the premise of the utility model creation design is not departed from, deformation can also be made and improved, should all belong to this practicality
New protection domain.
