Description
Technical field
The invention relates to a kind of manual cutting equipment, particularly a kind ofly not only can to have cut vertically downward but also can the mini saw of hand-held of straight cuts.
Background technology
The mini saw of hand-held comprises base plate, guard shield, motor assembly, saw blade, left and right body, handle, switch; base plate by torsion spring and left and right body hinged; switch-linear hybrid is on handle; switch is provided with the unlock button that can move left and right; base plate is provided with limited step; guard shield is fixed on base plate, is used for protecting saw blade.Due to than traditional electric circular saw applied range, both can degree of depth cutting vertically downward, again can straight cuts, a tractor serves several purposes, has obtained the accreditation of consumers in general.But the mini saw of hand-held in use exists following problem: one is when off working state, due to security needs, body and base plate are locked, and will could carry out cutting operation by unlock button action by lower body.Two is that existing unlock button can only a direction action, generally arranges by right-hand operated, just very inconvenient for left handed user.Three is that switch itself is provided with a unlock button, adds the unlock button for spacing base plate, just there are two unlock buttons like this at a machine, and operation uses extremely inconvenient, brings inconvenience to user.For this reason, many manufacturers and knowledgeable people develop for the defect of above-mentioned existence and develop, but not yet have comparatively ideal product to emerge so far.
Summary of the invention
For overcoming the mini saw above shortcomings of existing hand-held, the object of the invention is to provide the mini saw of a kind of hand-held that is simple and reasonable, easy for operation, that can unlock base plate again while unlock switch.
The invention solves the problems of the technologies described above adopted technical scheme, it comprises base plate, guard shield, motor assembly, saw blade, handle, switch, left and right body, base plate by torsion spring and left and right body hinged, switch-linear hybrid is on handle, switch is provided with the unlock button that can move left and right, base plate is provided with limited step, described left and right body is provided with floor locking mechanism, this mechanism comprises upper pendulum bar, draft link, spacer pin, described upper pendulum bar and draft link correspondence are hinged on the swing link bracket of left and right body, spacer pin is arranged on the left and right body that matches with limited step, the upper yaw of upper pendulum bar is hinged on unlock button, the lower yaw of upper pendulum bar matches with the upper notch of draft link, the lower end of draft link is connected on spacer pin, draft link can drive spacer pin to move axially.
The further preferred version of the invention, the upper notch of described draft link is provided with the ramp and lower inclined plane that match with the lower yaw of upper pendulum bar.
The further preferred version of the invention, described swing link bracket is combined by left and right swing link bracket, upper pendulum bar and draft link correspondence be hinged on left and right swing link bracket upper pendulum bar hinge and draft link hinge on.
The further preferred version of the invention, described spacer pin is provided with intermediate projections, and the inner side of spacer pin intermediate projections is provided with back-moving spring, and draft link is connected to the outside of spacer pin intermediate projections.
After adopting said structure, have the following advantages compared with the prior art and effect: due to upper pendulum bar hinged on the swing link bracket of left and right body and draft link, upper pendulum bar is hinged on unlock button, upper pendulum bar matches with the upper notch of draft link, the lower end of draft link is connected on spacer pin, unlock button on switch can link with floor locking mechanism, when unlock button moves left and right, unlock button can drive upper pendulum bar to swing, upper pendulum bar can drive spacer pin to move inward by draft link when swinging, limited step on spacer pin and base plate is departed from, thus while switch unlocks, realize base plate unblock, simple to operation, right-hand man can use, also left handed user is greatly facilitated.
