Description
Technical Field
The utility model relates to a chuck quick detach device of electronic screwdriver of multi-functional electric hand drill of infinitely variable belongs to the machine-building field.
Background
One of the most common power tools is a dc drill power screwdriver, which operates on a motor. The star wheel structure transmission then passes through chuck output torsion, and ordinary chuck all is fixed on the output shaft, in case damage just can only dismantle the change, and the replacement batch head that simultaneously can not be fine needs timely replacement chuck sometimes in work moreover, guarantees the process of work. The phenomenon that the clamping head clamps a workpiece firmly when the abrasion of the clamping head exceeds a certain limit can directly influence the processing precision and the production efficiency, and at the moment, the spring clamping head is scrapped, so that the manufacturing cost of the clamp is invisibly increased, and huge economic loss is caused.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: how to realize the quick dismantlement of chuck, how better make the chuck clip tight simultaneously sparingly the time of replacement chuck.
In order to solve the technical problem, the technical scheme of the utility model a chuck quick detach device that multi-functional electric hand drill electric screwdriver of infinitely variable speed is provided, a serial communication port, including chuck support, chuck support's inside be equipped with output shaft assorted hexagonal pole, hexagonal pole's side is equipped with the steel ball, chuck support's the outside is equipped with the spring, the spring is connected with the button subassembly, the button subassembly is connected with chuck support's the outside, is equipped with the jump ring at button subassembly and chuck support's junction end, the button subassembly is connected with the protecgulum.
Preferably, a steel ball sliding rail is arranged in the chuck support.
Preferably, the button assembly is arranged on the outer side of the left part of the chuck bracket and connected with the front cover.
The core component of the utility model is a chuck bracket. Therefore, the utility model has the characteristics of can make things convenient for quick dismantlement chuck, save the time of work, improve work efficiency, reduce the waste of material resource.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 4, the chuck quick-release device of the electric screwdriver of the multifunctional stepless speed change electric hand drill is characterized by comprising a chuck support 1, a hexagonal rod 2 matched with an output shaft 8 is arranged inside the chuck support 1, steel balls 3 are arranged on the side face of the hexagonal rod 2, a spring 6 is arranged on the outer side of the chuck support 1, the spring 6 is connected with a button assembly 5, the button assembly 5 is connected with the outer side of the chuck support 1, a clamp spring 4 is arranged at the tail end of the joint of the button assembly 5 and the chuck support 1, and the button assembly 5 is connected with a front cover 7.
Be equipped with on the output shaft 8 and construct the groove, there is the hole of hexagonal type in the output shaft, when chuck quick detach device ann was on output shaft 8, the draw-in groove of output shaft 8 was blocked to the steel ball in the chuck support 1, and hexagonal pole 2 is connected with output shaft 8, and snap spring 4 blocks button assembly 5 simultaneously and realizes fixing, when dismantling. The button assembly 5 is pressed to press the spring 6 to move radially, so that the chuck support (1) is not connected with the output shaft 8, and the disassembly is realized.
