The utility model discloses an electric tool capable of optimizing current carrying capacity of a microswitch, which comprises an electric tool main body, wherein the lower end of the electric tool main body is hinged with a button; the extrusion device comprises a fixed sleeve, a movable sleeve and a spring, wherein the fixed sleeve is fixed in the rear end of the button, the front end of the button is hinged with the lower end of the electric tool main body, the movable sleeve is positioned above the fixed sleeve, the spring is clamped between the fixed sleeve and the movable sleeve in an extending manner up and down, and the upper end face of the movable sleeve is pressed at the lower end of the contact. After the button is pressed, the contact of the micro switch is pressed through the extrusion device, and when a hand of a user pressing the button is loosened a little, the contact can not be loosened as long as the elastic force of the spring is larger than the elastic force of the reset spring in the micro switch, and the contact is kept in a pressed state.
Description
Technical Field
The utility model relates to the technical field of electric tools, in particular to an electric tool capable of optimizing current carrying capacity of a micro switch.
Background
In the prior art, when the electric tool, such as an electric saw, is used, after the switch is pressed by a hand, the contact of the micro switch is pressed by the switch, so that the electric tool starts to work, and then stops working after being released, however, people need to continuously press the switch to keep the machine working when using the electric tool, the time is long, which can cause that the hand can have some looseness, and after looseness, the contact is pushed by the reset spring of the micro switch, so that the contact of the micro switch is not pressed completely. When the contact of the micro-switch is pressed, the current carrying capacity of the micro-switch is strong, the current carrying capacity is poor when the pressing is not tight, and the micro-switch is easy to burn out when the contact is bad seriously.
Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, an object of the present utility model is to: a power tool is provided that optimizes the current carrying capability of a microswitch.
The technical scheme of the utility model is as follows: the electric tool comprises an electric tool main body, wherein the lower end of the electric tool main body is hinged with a button, a micro switch is arranged in the lower end of the electric tool main body, the lower end of the micro switch is provided with a contact, and an extrusion device for extruding the contact of the micro switch is arranged in the button;
the extrusion device consists of a fixed sleeve, a movable sleeve and a spring, wherein the fixed sleeve is fixed in the rear end of the button, the front end of the button is hinged with the lower end of the electric tool main body, the movable sleeve is positioned above the fixed sleeve, the spring is clamped between the fixed sleeve and the movable sleeve in a vertically extending manner, and the upper end face of the movable sleeve is pressed at the lower end of the contact.
Further, the button has a cavity with an opening facing upwards, and the pressing device is mounted in the cavity.
Further, the movable sleeve is provided with a movable groove with a downward opening, and the movable groove is used for the fixed sleeve to extend in.
Further, the fixed sleeve is provided with a groove with an upward opening, a convex column is arranged in the middle of the movable groove, the upper end of the spring is sleeved on the convex column, and the lower end of the spring extends into the groove.
The electric tool capable of optimizing the current carrying capacity of the micro switch has the beneficial effects that: after the button is pressed, the contact of the micro switch is pressed through the extrusion device, and when a hand of a user pressing the button is loosened a little, the contact can not be loosened as long as the elastic force of the spring is larger than the elastic force of the reset spring in the micro switch, and the contact is kept in a pressed state.
Drawings
FIG. 1 is a schematic diagram of the overall structure of the present utility model;
fig. 2 is an enlarged schematic view of the area a in fig. 1.
The figure shows: 1-electric tool main body, 2-button, 21-cavity, 3-micro switch, 31-contact, 4-fixed sleeve, 41-groove, 42-convex column, 5-movable sleeve, 51-movable groove and 6-spring.
Detailed Description
For a more visual and complete understanding of the technical solution of the utility model, non-limiting features will now be described with reference to the accompanying drawings, in which:
as shown in fig. 1 and 2, an electric tool capable of optimizing the current-carrying capacity of a micro switch comprises an electric tool main body 1, wherein a button 2 is hinged at the lower end of the electric tool main body 1, a micro switch 3 is arranged in the lower end of the electric tool main body 1, a contact 31 is arranged at the lower end of the micro switch 3, and an extrusion device for extruding the contact 31 of the micro switch 3 is arranged in the button 2; the extrusion device comprises a fixed sleeve 4, a movable sleeve 5 and a spring 6, wherein the fixed sleeve 4 is fixed in the rear end of the button 2, the front end of the button 2 is hinged with the lower end of the electric tool main body 1, the movable sleeve 5 is positioned above the fixed sleeve 4, the spring 6 is clamped between the fixed sleeve 4 and the movable sleeve 5 in a vertically extending manner, and the upper end face of the movable sleeve 5 is pressed at the lower end of the contact 31.
As shown in fig. 2, the push button 2 has a cavity 21 opening upwards for easy installation of the pressing means, which is installed in the cavity 21.
As shown in fig. 2, in order to facilitate the upward movement of the fixed sleeve 4, the movable sleeve 5 has a movable groove 51 with a downward opening, and the movable groove 51 is provided for the fixed sleeve 4 to extend in.
As shown in fig. 2, in order to facilitate the installation of the spring 6, the fixed sleeve 4 has a groove 41 with an upward opening, a convex column 42 is provided in the middle of the movable groove 51, the upper end of the spring 6 is sleeved on the convex column 42, and the lower end of the spring 6 extends into the groove 41.
When the push button 2 is pressed, the push button 2 drives the fixed sleeve 4 to move upwards, the spring 6 is compressed, and when the elastic force of the spring 6 after being pressed is larger than that of the reset spring 6 (not shown) in the micro switch 3, the movable sleeve 5 also moves upwards and presses the contact 31 until the contact 31 is pressed. When the user presses the button 2 with a little looseness of his hand, the contact 31 will not loosen and the contact 31 will remain pressed as long as the spring force of the spring 6 is still greater than the spring force of the return spring 6 in the microswitch 3.
It should be understood, however, that the description herein of specific embodiments is not intended to limit the scope of the utility model, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
