Conventional power tools typically employ a hand-held mode of operation, in which a switch for controlling a motor is typically integrated into the handle of the tool. At present, the internal switch of a handheld electric tool in the market, such as an angle grinder, is often complex in structure, which results in large occupied space and high production cost. The rapid development of the production and manufacturing industry at any time leads to the great increase of the demand of the handheld electric tool, and the problem that how to design a switch with simple and compact structure and low manufacturing cost is urgently needed to be solved at present.

SUMMERY OF THE UTILITY MODEL

The utility model provides a switch on the hand tool, simple structure, the transmission is reliable, can greatly reduced manufacturing cost to prior art not enough.

The utility model provides a technical scheme that its technical problem adopted is: a switch on a hand tool, comprising: a housing having a mounting portion formed thereon; a switch fixed to the mounting portion; an operating member disposed at least partially outside the housing; and the first end of the push rod is connected to the operating piece, and the second end of the push rod is used for triggering the switch. The operating piece is a push button which is arranged outside the shell in a sliding mode; the switch is a ship-type switch. The push rod is driven to move after the push button slides, and the opening of the ship-shaped switch is controlled, so that the whole structure is more compact, and meanwhile, the cost of the ship-shaped switch is low, the whole cost is reduced, and the reliability of transmission is also ensured.

In the above technical scheme, further, still be provided with on the installation department and be used for preventing the spacing portion of annular that the push rod deviate from. By the arrangement, the problem that the tail end is separated due to the length of the push rod can be avoided.

In the above technical solution, further, a second end of the push rod is provided with a trigger portion protruding towards the switch direction. Through this trigger part, the shift knob on the control ship type switch of can being more convenient for the push rod carries out less displacement and can accomplish and trigger.

In the above technical solution, further, the middle area of the push rod is in sliding fit with the inner wall of the housing. Set up like this, be favorable to guaranteeing the rotational stability of push rod, avoid it to take place the skew.

Among the above-mentioned technical scheme, furtherly, still include the tail-hood, the tail-hood with the cooperation is dismantled to the casing for cover the installation department of casing reaches the second end of push rod.

In the above technical solution, further, the push rod further includes a spring for driving the push rod to move toward the second end. The switch is characterized in that a limiting column is arranged on the inner side of the transition region of the push rod, a limiting column is also arranged on the shell opposite to the transition region, the spring is arranged between the two limiting columns, and the push rod is driven by the spring to automatically move towards the tail under the condition of no stress, so that the switch is switched off.

The utility model has the advantages that: the push rod is controlled to move through the push button outside, so that the ship-shaped switch is triggered, the structure is reliable in transmission, the inside is more compact while the same function is achieved, and meanwhile, the production cost is lower.

In the figure, 1, a shell, 2, a mounting part, 3, a ship-shaped switch, 31, a reset button, 4, a push button, 5, a push rod, 6, an annular limiting part, 7, a triggering part, 8, a tail cover, 9, a spring, 10, a limiting buckle, 11, a limiting groove, 12, a first limiting column and 13, a second limiting column are arranged.

Detailed Description

Referring to fig. 1-5, a switch on a hand tool includes: the device comprises a shell 1, wherein a mounting part 2 is formed on the tail end of the shell 1; a boat-shaped switch 3 is fixedly embedded and installed on the base of the installation part 2, and a reset button 31 capable of automatically resetting is arranged on the boat-shaped switch 3; a push button 4 in sliding fit with the shell 1 is arranged on the outer part of the shell 1, and a limit buckle 10 extending into the shell 1 is arranged on the push button 4; a push rod 5 is slidably fitted in the housing 1, a first end of the push rod 5 is provided with a limit groove 11, the limit groove is matched with a limit buckle 10 on the push button 4, the push rod is connected to the push button 4, and a second end of the push rod 5 extends to the upper end area of the boat-shaped switch 3. And the spring 9 is used for driving the push rod 5 to move towards the second end direction. Specifically, a first limit post 12 is arranged on the inner side of the transition region of the push rod 5, a second limit post 13 is arranged on the shell 1 opposite to the first limit post, the spring 9 is arranged between the two limit posts, and the spring 9 is used for driving the push rod 5 to automatically move towards the tail under the condition of no stress, so that the switch is switched off. When the push button is used, the push button 4 slides forwards to drive the push rod 5 to move towards the first end of the push rod, so that the push rod drives the reset button 31 of the ship-shaped switch 3 to move, and a circuit is in a power-on state; when the push button 4 is released, the push rod 5 will return automatically under the action of the spring 9, so that the reset button 31 on the ship-shaped switch 3 is also reset to the initial state, and the circuit is disconnected.

In order to avoid the tail end from falling off due to the fact that the push rod 5 is too long, the installation part 2 is further provided with an annular limiting part 6, and the second end of the push rod 5 is arranged in the area between the annular limiting part 6 and the ship-shaped switch 3.

Further, a second end of the push rod 5 is provided with a trigger part 7 protruding toward the ship switch 3. The trigger unit 7 can control the reset button 31 of the ship switch 4 more easily, and the push rod 5 can be triggered by a small displacement.

Further, still include tail-hood 8, tail-hood 8 with the cooperation is dismantled to casing 1 for cover the installation department 2 of casing 1 reaches the second end of push rod 5.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and the present invention is not departed from the technical solution of the present invention, and the made simple modification, equivalent change or modification all fall into the protection scope of the present invention.
