[0016] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] Referring to Figs. 1-3 As shown in the drawings, the embodiments of the present application disclose a pruning machine, which comprises a shell assembly 1 and a button 2; the button 2 is connected to the bottom of a handle 11 in the shell assembly 1; the rear end of the button 2 is rotationally connected with the handle 11, and the front end of the button 2 is embedded with a first spring between the handle 11; when the button 2 is pressed, the button 2 is used to trigger the trigger end of a trigger switch located inside the handle 11 to make the trigger switch conductive; when the button 2 is released, the first spring is used to drive the button 2 to rotate and reset, and the front end of the button 2 abuts against the shell assembly 1; the inner bottom of the middle part of the button 2 is provided with a plurality of convex ribs 21 which are spaced apart from front to back, each of the convex ribs 21 extends from bottom to top, and the spacing between each adjacent two convex ribs 21 is less than the width of the trigger end of the trigger switch.
[0018] After the plurality of convex ribs 21 are arranged on the inner bottom of the middle part of the button 2, since the spacing between each adjacent two convex ribs 21 is less than the width of the trigger end of the trigger switch, even if there is a certain assembly error between the trigger switch and the button and the shell assembly after the trigger switch and the button are assembled with the shell assembly, it can be ensured that the convex rib on the button can reliably trigger the trigger end of the trigger switch when the button is pressed, that is, the reliability of the pruning machine during use can be ensured. In addition, in the present application, the size of the convex rib on the original button is not directly increased, the purpose is to facilitate the demolding of the button after injection molding, and if the size of the convex rib is directly increased, when the convex rib is injection molded and cooled, the outer surface of the button at the position of the convex rib will appear to be shrunk, that is, the appearance of the button will be affected. Through the arrangement of the plurality of convex ribs, the demolding of the button is facilitated, and the formation of the shrinkage on the outer surface of the button can be avoided.
[0019] The convex ribs 21 are provided with three rows, and the three rows of convex ribs 21 are integrally formed on the inner bottom of the button 2; after the structure is adopted, when the button is pressed, the convex ribs can reliably trigger the trigger end of the trigger switch to make the trigger switch conduct, that is, the reliability when the trigger end of the trigger switch is triggered can be improved; and since the convex ribs are integrally formed on the inner bottom of the button, the convex ribs have the advantage of high connection strength with the button.
[0020] The rear end of the button 2 is integrally formed with a rotating shaft 22, the handle 11 is provided with an open slot 111, and the rotating shaft 22 is clamped into the open slot 111 and rotationally connected with the open slot 111; after the structure is adopted, after the rotating shaft is clamped into the open slot, the rotating shaft can be rotationally connected with the open slot, so that the rear end of the button can be reliably rotationally connected with the handle.
[0021] The upper edge of the handle 11 is slidably connected with a push-torque 3, a second spring is embedded between the front end of the push-torque 3 and the shell assembly 1, and the second spring is used to drive the push-torque 3 to move back to reset; the front end of the button 2 is provided with a limiting column 24 from bottom to top, and the lower end of the push-torque 3 is provided with an abutting portion 31; after the push-torque 3 is moved back to reset, the abutting portion 31 abuts against the limiting column 24 to limit the button 2 from being pressed; after the structure is adopted, under the action of the push-torque, only when the push-torque is pushed forward (the abutting portion is released from the abutting state with the limiting column), the button can be pressed, that is, the situation that the button is pressed by mistake can be avoided, that is, the accidental start of the pruning machine can be avoided, and the safety hazard is eliminated; in addition, when the pruning machine is used, one hand holds the handle, then the thumb pushes the push-torque to move forward, and finally the button is pressed by other fingers, at this time, the button triggers the trigger end of the trigger switch to start the pruning machine.
[0022] The middle part of the limiting column 24 in the front-rear direction is provided with a reinforcing rib 23, and the reinforcing rib 23 extends from bottom to top and is integrally formed with the limiting column 24; after the structure is adopted, the fracture resistance of the limiting column can be improved.
[0023] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
