Abstract
The utility model relates to a safety switch device for a one-handed operated pneumatic tool, belonging to the pneumatic tool class, which comprises a shear pin, a safety button and a switch moving board. The utility model is characterized in that: a spring is arranged on the shear pin, the spring and the shear pin are arranged in the tool body hole, a shoulder is arranged on the shear pin, a pressure spring is arranged on the bottom of the safety button, the spigot of the safety button is matched with the shoulder of the shear pin, the switch moving board is arranged on the bottom of the shear pin, a switch touching pin is arranged on the top of the shear pin. The spigot of the safety button of the utility model is positioned in the shoulder of the shear pin under the effect of the pressure spring elasticity, thus the shear pin cannot be pressed down; the shear pin can be pressed down and the switch moving board can be screwed down, thus driving switch touching pin and making the switch motioning, only when the safety button is pressed down and the spigot of the safety button escapes from the shoulder of the shear pin. The utility model has the advantages of convenient operation, safety and reliability as that the whole operation process of the pneumatic tool can be finished by a hand after adopting the safety switch.
Description
Technical field
The utility model belongs to the pneumatic tool class, specifically is a kind of pneumatic tool safety switching apparatus of one-hand operation.
Background technology
Existing air tool safety switch, all be to adopt the way that on the moving plate of switch, increases by a push rod to play the effect of safety switch, but all need during this structure operation one hold machine, the another hand is stirred push rod and just can be pressed the moving plate of switch, thereby start the machine, owing to must operate simultaneously by both hands, cause operation very inconvenient; Especially impulsive force is very big when machine just starts, and only holds machine with one and be difficult to grasp the control machine, causes peril easily, so also safety inadequately.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of pneumatic tool safety switching apparatus of simple in structure, easy to operate, safe and reliable one-hand operation is provided.
The technical solution of the utility model is as follows:
A kind of pneumatic tool safety switching apparatus of one-hand operation, comprise safety switch, safety pin, the moving plate of switch, it is characterized in that: safety pin has spring, spring and safety pin are in the hole of pneumatic tool main body, one step is arranged on the safety pin, and stage clip is equipped with in the safety switch bottom, and the seam of safety switch can cooperate with the step of safety pin, the safety pin below has switch to move plate, and the moving plate of switch top also has a switch actuating pin.
The moving strip of switch of the present utility model has a position-limitting pin, is used for the moving Board position of limit switch.
Safety switch of the present utility model is a button that can limit the safety pin action, and in the step of the stop portion on the safety switch under the effect of stage clip elastic force at safety pin, this moment, safety pin can't be pressed; Have only when pressing safety switch, the safety switch seam breaks away from the safety pin step, and safety pin could be pressed, and also has only and at this moment waits and could depress switch move plate, thereby drive the switch actuating pin, makes switch motion.After adopting this safety switch, the whole operation process of pneumatic tool switch only needs a hand just can finish, and must use the history of two hands ability handling safety switches before changing.The utility model is simple in structure, and is easy to operate, and safe and reliable.
