Abstract
An outer hexagonal connection structure for a rechargeable gun drill connected with a fast assembled/disassembled drill chuck comprises a gun drill body containing a motor, a gearbox, a wire, a switch and a batter pack, wherein an outer hexagon is formed at the front end of a spindle of the gun drill and is matched with an inner hexagon fixed inside a central hole of the drill chuck, in order that the spindle of the gun drill drives the drill chuck to rotate for operation; the external diameter of the spindle of the gun drill is provided with a groove, and after the drill chuck is sleeved into the end point of the spindle of the gun drill, a steel ball on the wall of the central hole of the drill chuck can be automatically inserted into the groove on the spindle, so that the drill chuck cannot move axially but can be locked. The outer hexagonal connection structure is fast to assemble and disassemble, reliable to connect, and rational.
Description
Technical field
The armed brill of syndeton, especially multifunctional hand that the utility model relates to a kind of hand-held drill gun and drill chuck needs the anterior syndeton of drill gun easy to loading and unloading.
Background technology
The anterior main shaft of existing hand-held drill gun all is to be fixedly connected on transferring power on the drill gun main shaft and rotary work by screw with being connected of drill chuck; But it is inconvenient that screw connects loading and unloading; Time-consuming, take the labour, the application of the multiple drilling tool annex of the present multi-functional drill gun of incompatibility.
Summary of the invention
In order to overcome the weak point that existing hand-held drill gun main shaft is connected with drill chuck with screw, the utility model provides a kind of syndeton of not having the anterior main shaft of drill gun of screw connection.
The utility model solves the technical scheme that its ended questions adopted: comprise that the drill gun main body includes; Motor, gear-box, lead, switch, power brick; The drill gun front-end of spindle is shaped on outer-hexagonal; Made outer-hexagonal can match with the interior hexagonal that drill chuck mesopore inner end is fixed, so that the drill gun main shaft drives the drill chuck rotary operation; Also be shaped on groove on the drill gun main shaft external diameter, groove after drill chuck is inserted in drill gun main shaft terminal point in the drill chuck steel ball on the wall surface of the hole can automatically embed the main shaft upper groove, drill chuck no longer moved axially and be locked.
Owing to adopt above-mentioned technical scheme; The fixing interior hexagonal of the outer-hexagonal of drill gun front-end of spindle and drill chuck mesopore inner end match and the drill gun main shaft on groove; The steel ball on the wall surface of the hole embeds locking in the drill chuck when passing terminal point, and therefore loading and unloading are quick, connect reliable and secure.

The specific embodiment
The utility model is shaped on groove 1 on drill gun main shaft 3; Drill gun main shaft end face is shaped on outer-hexagonal 2;, the mesopore of drill chuck rotates after being inserted in the drill gun main shaft along with passing forward with suitable; This moment, the outer-hexagonal of drill gun front-end of spindle matched with the interior interior hexagonal of drill chuck mesopore, and the steel ball that wall surface of the hole is exposed in being pushed into the terminal point drill chuck also embeds the groove on the drill gun main shaft simultaneously, so drill chuck is locked on the main shaft; Can not move axially again and guarantee cooperatively interacting of interior hexagonal and outer-hexagonal, when Push switch drill gun main shaft drives the drill chuck rotary operation.
Claims (1)
- One kind with load and unload the charging drill gun outer-hexagonal syndeton that drill chuck efficiently is connected; Comprise that drill gun main body (3) includes; Motor, gear-box, lead, switch, power brick; It is characterized in that the drill gun front-end of spindle is shaped on outer-hexagonal (2), made outer-hexagonal can match with the interior hexagonal that drill chuck mesopore inner end is fixed, so that the drill gun main shaft drives the drill chuck rotary operation; Also be shaped on groove (1) on the drill gun main shaft external diameter, groove (1) after drill chuck is inserted in drill gun main shaft terminal point in the drill chuck steel ball on the wall surface of the hole can automatically embed the main shaft upper groove, drill chuck no longer moved axially and be locked.
