Summary of the invention
For overcoming the existing mini saw above shortcomings of hand-held, the purpose of the invention provides a kind of simple and reasonable, easy for operation, mini saw of hand-held that can carry out to base plate again release in unlock switch.
The invention solves the problems of the technologies described above the technical scheme that adopts, it comprises base plate, guard shield, motor assembly, saw blade, handle, switch, left and right sides body, base plate is hinged by torsion spring and left and right sides body, switch is arranged on the handle, but switch is provided with the unlock button of move left and right, base plate is provided with limited step, described left and right sides 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 sides body, spacer pin is arranged on the left and right sides body that matches with limited step, the upper yaw of upper pendulum bar is hinged on the unlock button, the lower yaw of upper pendulum bar matches with the upper notch of draft link, and the lower end of draft link is connected on the spacer pin, and draft link can drive spacer pin and move axially.
The further preferred version of the invention is provided with ramp and the lower inclined plane that matches with the lower yaw of upper pendulum bar on the upper notch of described draft link.
The further preferred version of the invention, described swing link bracket is combined by left and right sides swing link bracket, and upper pendulum bar and draft link correspondence are hinged on the upper pendulum bar hinge and draft link hinge of left and right sides swing link bracket.
The further preferred version of the invention, described spacer pin is provided with intermediate projections, and the inboard 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: owing to hinged upper pendulum bar and draft link on the swing link bracket of left and right sides body, upper pendulum bar is hinged on the unlock button, upper pendulum bar matches with the upper notch of draft link, the lower end of draft link is connected on the spacer pin, unlock button on the switch can link with floor locking mechanism, when the unlock button move left and right, unlock button can drive upper pendulum bar and swing, upper pendulum bar can drive spacer pin by draft link and move inward when swinging, limited step on spacer pin and the base plate is broken away from, thereby in the switch release, realize the base plate release, simple to operation, the right-hand man can both use, and also greatly facilitates left handed user.
