Problems solved by technology
[0003] At present, the switch of ice drills on the market has multiple buttons. Due to the heavy weight of ice drills, in practical applications, operators often need to apply a large force to lift the equipment to carry out drilling operations. , it is often inconvenient to operate the button; in addition, when people are operating or moving the machine, they are likely to press the switch by mistake, causing the ice drilling equipment to start by mistake, which is easy to hurt the human body

Embodiment Construction
[0033] As mentioned in the background art, the switch design of the existing ice drilling equipment is not convenient for human operation, and there are also potential safety hazards.
[0034]In order to improve the safety performance of the switch structure of the ice drill equipment, in some embodiments, the switch of the ice drill is designed as a double-action switch. The switch was turned on and the machine was officially started. The disadvantage of this design is: when the machine is in danger, for example, when the ice drill rolls into the sundries, the machine cannot let go, because the four fingers hold the machine, the fingers cannot release the switch quickly; When using the machine, the four fingers need to work together with the palm. At this time, the four fingers have already pressed the switch, and the thumb cannot smoothly push the push button, which is very inconvenient to operate.
[0035] In order to solve the above technical problems, the embodiment of t...

Provided are a switch structure and an ice drill. The switch structure comprises a switch for turning on a power supply when being turned on, or turning off the power supply when being closed; a button for controlling opening or closing of the switch; and a trigger structure. One end of the trigger structure is movable between the button and the switch, and when one end of the trigger structure iswithin a preset position range between the button and the switch, the switch is in a closed state, and the button cannot be used to control turning-on of the switch. When one end of the trigger structure is outside the preset position range, the button can be used to control on-off of the switch. The switch structure of the embodiment is a double action switch, preventing an operator from accidentally touching the switch during use, and the double action switch meets requirements of safety regulations. The switch structure can preferably imitate ergonomics and improve operation performance.
Description
technical field [0001] The invention relates to the technical field of electric drills, in particular to a switch structure and an ice drill. Background technique [0002] Ice-drilling equipment is required for ice-breaking operations in the cold winter. Commonly used ice-drilling equipment includes portable ice drills and tractor-mounted ice drills. [0003] At present, the switch of ice drills on the market has multiple buttons. Due to the heavy weight of ice drills, in practical applications, operators often need to apply a large force to lift the equipment to carry out drilling operations. , It is often inconvenient to operate the button; in addition, when people are operating or moving the machine, they may press the switch by mistake, causing the ice drilling equipment to start by mistake, which is easy to hurt the human body. [0004] Therefore, there is a need for a switch structure for an ice drill that is convenient for personnel to operate and has a high safety f...
