Abstract
The utility model provides a kind of short formula hand fastening drill clutch, and comprise drill body, jaw, nut, rotary sleeve, nut and jaw are threaded, and rotary sleeve drives nut rotation by syndeton and drives jaw to move forward and backward; Drill body shortens to its rear end and is in rotary sleeve; Drill body rear portion cylindrical extended matching to the inner surface with rotary sleeve and radial support stabilization is played to the rear portion of rotary sleeve; The rear portion opened of drill chuck, forms the spatial accommodation entered into for the front portion of drive unit in rotary sleeve rear end surrounded by rotary sleeve the rear end from the rear end of rotary sleeve to drill body.The utility model can not arrange rear cover and not affect the stability of drill chuck, drive unit can stretch in the scope of rotary sleeve, jaw can utilize the space outside drill chuck when retreating, therefore hand fastening drill clutch can be done short as much as possible, can reduce its be connected to pistol electric drill after pistol electric drill total length, be convenient to the instrument cases that the supporting composition of the parts such as pistol electric drill and drill bit one is less.
Description
Technical field
The utility model relates to hand fastening drill clutch field.
Background technology
In prior art, in hand fastening drill clutch, be provided with drill body, jaw, nut, rotary sleeve, manually rotate rotary sleeve and drive nut rotation thus drive jaw to travel forward or move backward and drill chuck is clamped or the drilling tool that gets loose.Hand fastening drill clutch is cover or bonnet after the rear of rotary sleeve is also arranged generally, also, traditional hand fastening drill clutch, the rear end of its rotary sleeve the middle part of the entire length of drill chuck or middle part slightly biased after.In some occasion, this traditional hand fastening drill clutch is oversize, is not easy to the instrument cases smaller with supporting compositions of execution unit one such as drill bits.
Summary of the invention
Technical problem to be solved in the utility model is to provide the shorter short formula hand fastening drill clutch of a kind of more traditional hand fastening drill clutch length.For this reason, the utility model is by the following technical solutions:
A kind of short formula hand fastening drill clutch, comprise drill body, jaw, nut, rotary sleeve, described nut and jaw are threaded, and rotary sleeve drives described nut rotation by syndeton and drives jaw to move forward and backward; It is characterized in that described drill body shortens to its rear end and is in rotary sleeve; The rear portion cylindrical of described drill body extended matching to the inner surface with described rotary sleeve and radial support stabilization is played to the rear portion of rotary sleeve; The rear portion opened of described drill chuck, forms the spatial accommodation entered into for the front portion of drive unit in rotary sleeve rear end surrounded by rotary sleeve the rear end from the rear end of rotary sleeve to drill body.
Further, the contraction in length of described rotary sleeve is to described jaw can stretch out outside the rear end of rotary sleeve back to during the limit, and the rear inside of described rotary sleeve becomes taper seat configuration.
Further, the front portion of described drive unit refers to that the motor of pistol electric drill is anterior.
Owing to adopting the technical solution of the utility model, hand fastening drill clutch provided by the utility model, rear cover can not be set and not affect the stability of drill chuck structure, and, the drive unit of hand fastening drill clutch can extend in the scope of rotary sleeve always, and jaw can utilize the space outside drill chuck when retreating, therefore, hand fastening drill clutch can be done short as much as possible, and can reduce its be connected to pistol electric drill after pistol electric drill total length, be convenient to the instrument cases that the supporting composition of the execution unit such as pistol electric drill and drill bit one is smaller.
Accompanying drawing explanation
Fig. 1 be embodiment provided by the utility model partly cut open schematic diagram.
Fig. 2 is the drill body schematic diagram of embodiment provided by the utility model.
Fig. 3 is the rotary sleeve schematic diagram of embodiment provided by the utility model.
Detailed description of the invention
With reference to accompanying drawing.Short formula hand fastening drill clutch provided by the utility model, comprises drill body 1, jaw 3, nut 4, rotary sleeve 2, and described nut 4 and jaw 3 are threaded, and rotary sleeve 2 drives described nut 4 to rotate by syndeton and drives jaw 3 to move forward and backward; Described drill body 1 shortens to its rear end 10 and is in rotary sleeve 2; The rear portion cylindrical 11 of described drill body 1 extended matching to the inner surface 21 with described rotary sleeve and radial support stabilization is played to the rear portion of rotary sleeve 2, like this, overlap after the rear portion of drill chuck can not be arranged, contribute to drill chuck to do short, rotary sleeve 2 all relies on drill body 1 to obtain radial support and stable at anterior or rear portion; The rear portion opened of described drill chuck, forms the spatial accommodation 200 entered into for the front portion of driving device in the rear end 20 of rotary sleeve surrounded by rotary sleeve 2 rear end 10 from the rear end 20 of rotary sleeve 2 to drill body.
The contraction in length of described rotary sleeve 2 to described jaw 3 can stretch out outside the rear end 20 of rotary sleeve back to during the limit, and the rear inside 22 one-tenth taper seat configuration of described rotary sleeve.
The front portion of described drive unit refers to that the motor of pistol electric drill is anterior.Drawing reference numeral 12 is the hole for being connected with driving shaft of drill body, and described driving shaft is driven by described drive unit.
Claims (3)
1. a short formula hand fastening drill clutch, comprises drill body, jaw, nut, rotary sleeve, and described nut and jaw are threaded, and rotary sleeve drives described nut rotation by syndeton and drives jaw to move forward and backward; It is characterized in that described drill body shortens to its rear end and is in rotary sleeve; The rear portion cylindrical of described drill body extended matching to the inner surface with described rotary sleeve and radial support stabilization is played to the rear portion of rotary sleeve; The rear portion opened of described drill chuck, forms the spatial accommodation entered into for the front portion of drive unit in rotary sleeve rear end surrounded by rotary sleeve the rear end from the rear end of rotary sleeve to drill body.
2. a kind of short formula hand fastening drill clutch as claimed in claim 1, the contraction in length that it is characterized in that described rotary sleeve is to described jaw can stretch out outside the rear end of rotary sleeve back to during the limit, and the rear inside of described rotary sleeve becomes taper seat configuration.
