Description
Technical field
The present invention relates to a kind of clamp mechanism, especially a kind of for annex is fixed to the clamp mechanism on work arbor releasedly; The invention still further relates to a kind of power tool with this clamp mechanism, especially a kind of power tool with annex being fixed to releasedly to the clamp mechanism on work arbor.
Background technology
There are in the market the various power tools with annex clamp mechanism, wherein a kind of power tool with annex clamp mechanism, comprise: drive the work arbor of annex, annex is fixed between the retaining part and tightening member of the end in the face of instrument of work arbor, make tightening member prop up at the off-position and the tightening member that remove tightening member from work arbor the mechanism moving between the clamped position by retaining part by spring element, tightening member comprises the clamp shaft that can be inserted in work arbor, clamp shaft remains in clamped position by the latch assembly in work arbor, and can be removed in off-position, latch assembly has the collar, clamping component can move radially in the recess that remains on the collar and against the collar, clamping component has the inclined surface coordinating with the inclined surface on the collar in the side towards instrument, make the collar cause the shock on clamping component towards center against the athletic meeting of the inclined surface of clamping component, to be work arbor do oscillating motion around self axis to the operation principle of this power tool, it further comprises casing, be arranged on the motor in casing, by motor-driven main shaft, main shaft has the eccentric part of a rotation and the setting of offset rotation axis, one shift fork is connected on working cell by main shaft drives manipulation, one end of shift fork is pivotally connected on work arbor, the other end is formed with the fork of a pair of branch and is stuck on the eccentric part on main shaft, work arbor is vertical substantially with main shaft rotation, thereby main shaft converts shift fork to around the rotation of rotation and moves and work arbor is moved and drive annex work along the pivot of work arbor.And on work arbor, be provided with after different annexes as user, can realize multiple different operating function.Common annex comprises straight blade, saw blade, triangle frosted dish, scraper etc., can realize as work requirements such as sawing, cut, grind, scrape.
But, the annex clamp mechanism of above-mentioned power tool, in dispose procedure, user must together remove clamp shaft and annex, same, in clamping process, user also must together be clamped in clamp shaft and annex on work arbor, this method of clamping has brought operational inconvenience, once user has lost clamp shaft accidentally in addition, annex clamp mechanism cannot be carried out work, power tool with this annex clamp mechanism also cannot be worked, also have this annex to clamp mechanism structure complexity, required part is more, and cost is comparatively expensive.
In addition, also have a kind of power tool with this annex clamp mechanism, it comprises the tool body that motor is housed; Comprise the clamp assembly of the first clamping component, it moves between closing position and release position with respect to annex, keep annex at closing position clamp assembly, depart from and allow annex to remove from clamp assembly at the first clamping component of release position clamp assembly and annex, the first clamping component keeps connecting with clamp assembly simultaneously; There is the actuator that operating parts divides, this actuator is attached to movingly tool body between primary importance and the second place, in the close position at primary importance clamp assembly, the motion dividing at the operating parts of second place actuator causes clamp assembly to move to release position.
But, while using this annex clamp mechanism to carry out clamping annex, the shank of its annex must pass from work arbor, therefore the shank of its annex is provided with opening, thereby realize, the annex of shank opening is clamped or discharged, its annex that shank is remained silent cannot clamp or discharge, and has reduced the versatility of this annex clamp mechanism.
Summary of the invention
In order to solve the defect existing in above-mentioned prior art, be necessary to provide a kind of simple in structure, without additional lock mandrel and the high annex clamp mechanism of annex versatility and with the power tool of this annex clamp mechanism.
