Abstract
The utility model discloses a multi-head electric tool which comprises a machine head shell (1) and a machine body shell (2), wherein a locking mechanism is arranged between the machine head shell (1) and the machine body shell (2), a head replacing locking ring (3) is arranged inside the inner cavity of the machine head shell (1), a plurality of clamping blocks (3.1) are arranged on the inner wall of the head replacing locking ring (3), a boss (4) matched with the head replacing locking ring (3) is arranged at the front end of the machine body shell (2), a plurality of grooves matched with the clamping blocks (3.1) are arranged on the outer peripheral surface of the boss (4), each groove is formed by communicating a guiding groove (4.1) vertically arranged and a clamping groove (4.2) transversely arranged, and the clamping blocks (3.1) are clamped in the clamping grooves (4.2). By adopting the multi-head electric tool, the misoperation can be effectively avoided; and the connection between the machine heads and the machine body is firmer.
Description
Technical field
The utility model relates to field of power tools, particularly a kind of bull electric tool.
Background technology
The kind of electric tool is many, as: polishing machine, sanding machine, sander, drill gun, power shovel etc., these electric tool small volume and less weights; Use flexibly, though effect is different, its principle is mostly similar; Mostly have fuselage and head, have drive motors in the fuselage, the output shaft of drive motors is delivered to power through transmission component the work package of head; Make work package produce rotation or shake, correlation functions such as realizing polishing, polishing, sanding, curvilinear cut, hole or root out.In order to save cost; A kind of bull combined electric instrument has appearred on the market, removable connection between the head shell of this instrument and the body shell, and the user is installed in different heads on the fuselage according to need of work; Need not to purchase the electric tool of many difference in functionalitys, saved purchase cost.The concrete structure of this bull combined electric instrument is: the motor of fuselage is connected with the work package of head through the output precision of pegging graft; Removable connection between head shell and the body shell; An end that is meant head shell is provided with draw-in groove, and the front portion of being located at the button on the body shell is provided with the clamping hook that matches with above-mentioned draw-in groove.But problem is the easily maloperation and press button in use of this electric tool, and at this moment the anterior clamping hook of button just can be deviate from from draw-in groove, and then head and fuselage are thrown off, and influence is use normally.
Summary of the invention
The utility model technical problem to be solved is: provides a kind of and can effectively avoid maloperation, and the more firm bull electric tool of the connection between head and the fuselage.
The utility model addresses the above problem the technical scheme that is adopted: a kind of bull electric tool; Comprise head shell and body shell; Be provided with lockable mechanism between described head shell and the body shell; The inner chamber of described head shell is provided with and changes a retainer, and the described inwall that changes a retainer is provided with a plurality of fixture blocks; Described body shell front end is provided with and changes the boss that a retainer matches; The outer circumference surface of described boss is provided with a plurality of grooves of matching with fixture block of being used for; Described groove is connected by the gathering sill of vertical setting with the draw-in groove of horizontally set and forms, and described fixture block is sticked in the described draw-in groove.
Compared with prior art, the advantage of the utility model is: a retainer that changes of this bull electric tools head capsule intracoelomic cavity is provided with a plurality of fixture blocks, and the outer circumference surface of the boss of body shell front end is provided with the groove that matches with fixture block; And groove is made up of gathering sill and draw-in groove; When changing head, the boss on the body shell is sleeved on a retainer place that changes of head shell like this, and will changes the vertical gathering sill embedding in fixture block edge of a retainer; And head shell rotated a certain angle; Fixture block is sticked in the horizontal draw-in groove, and by lockable mechanism locking, very convenient quick.And in use, be difficult for taking place to make because of maloperation the phenomenon of head and fuselage disengagement, the connection between head and the fuselage is more firm.
As preferably, described lockable mechanism comprises the push button assembly of being located at body shell, be located at the locking bar of push button assembly front end and be located at the back-moving spring of push button assembly rear end, and described head shell is provided with the stopper slot that matches with described locking bar.Like this, after changing head and accomplishing, can carry out locking to head shell and body shell through the cooperation of locking bar and stopper slot; In the time of need changing head once more, only need be with push button to pusher, locking bar is deviate from stopper slot under the effect of back-moving spring, can change the head operation, and is very convenient.
As preferably, the upper end of described boss is provided with the conical surface, and described fixture block is provided with the inclined-plane that matches with the described conical surface.Like this, the conical surface on the boss and the inclined-plane of fixture block can play the effect of guiding, and be like this, more convenient when the replacing head is reinstalled.
As preferably, the quantity of described fixture block is four, and described four fixture blocks are distributed in the described inwall that changes a retainer.
