Summary of the invention
The utility model mainly is to solve the existing in prior technology operator or other people careless (non-original idea) opens the diagonal cutting saw switch, thereby diagonal cutting saw is started working and caused the technical problem of danger etc. to operator or other people.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the anti-self-locking device of diagonal cutting saw switch, described diagonal cutting saw comprises support, head-shield, is located at the saw blade in the head-shield, the operation handle that links to each other with head-shield, be arranged at the switch open device on the described operation handle, and between switch is by handle and switch, being provided with the switch connecting rod, described switch connecting rod is connected with locking press button by tapered end.When pressing shift knob, described switch connecting rod retaining is pressed between handle and the switch at switch, helps preventing causing danger to operator or other people operator or other people careless (non-original idea).
As preferably, the nearly described switch of described switch connecting rod is provided with the connecting rod projection by the switch on the handle by handle projection place.Help when pressing described switch by handle, switch contacts with described connecting rod projection by the handle projection, thereby can't open switch.
As preferably, have through hole around the shift knob of described switch connecting rod on described switch, described shift knob passes described through hole, and the position of described shift knob is corresponding with the position that described switch is pressed the handle projection.Help effectively realizing that shift knob is pressed to open switch or be not pressed prevents to open switch; When needs are opened switch, shift knob is pressed by the handle projection by described switch; Be unlocked when needs prevent switch, described switch is against on the connecting rod projection by the handle projection.
As preferably, described switch connecting rod one end flexibly connects with described tapered end, is provided with spring between the other end and the described handle.Help connecting rod and move according to actual needs, when needs reset, under the effect of spring, provide convenience simultaneously.
As preferably, described locking press button is arranged on the described operation handle.Help operation and make, make simultaneously and diagonal cutting saw complete machine compactness as a result reduce manufacturing cost.
As preferably, described tapered end is nearly sector structure, and the circle centre position of described tapered end sector structure is movably connected on the described handle, and contact movable respectively on the fan-shaped cambered surface of described tapered end has described locking press button and described switch connecting rod.Help switch connecting rod move left and right smoothly, the unlatching that helps effectively realizing switch whether.
As preferably, described switch connecting rod is provided with in recessed Cao that described spring terminal is nested in described handle.Help convenient the manufacturing and the anti-self-locking device of installation diagonal cutting saw switch, help the maintenance of the anti-self-locking device of diagonal cutting saw switch again.
Therefore, the utlity model has rational in infrastructure, compact; Low cost of manufacture; Installation, maintenance is convenient; Simple to operate; Operator or other people careless (non-original idea) are when pressing the diagonal cutting saw switch, help preventing that diagonal cutting saw from starting working causes characteristics such as danger to operator or other people.
