Referring to fig. 2 and 3, the trigger 2 includes a trigger body 21, a rotating shaft 22 located at one end of the trigger and connected to a first engaging portion 31, a boss 24 located on an upper surface 23 of the trigger body 21, and a cylinder 25, which is mainly used to cooperate with the unlocking mechanism 3 and the switch button 4 to control the on/off of the switch 5.
The trigger body 21 is rotatable about a rotation axis 22 and moves the unlocking mechanism 3 between an unlocking position and a locking position between the switch knob 4 and the switch 5. The boss 24 allows the upper portion of the trigger body 21 to be caught in the housing cavity 11 of the housing 1, and the lower portion of the trigger body 21 to be exposed from the housing cavity 11, so that the operator can push up the trigger 2. The cylinder 25 is sleeved with a spring 251, and two ends of the spring 251 are respectively abutted against the upper surface 23 of the trigger 2 and the shell 1; when the operator releases the trigger 2, the trigger 2 returns to the initial position under the action of the spring 251.
The unlocking structure 3 includes a first engagement portion 31 connected to the trigger 2 and a second engagement portion 32 engaged with the first engagement portion 31. In a preferred embodiment, the unlocking structure 3 is made of plastic, so that mass production of the unlocking structure can be realized through injection molding of a mold. In other embodiments, the unlocking structure 3 may be made of any suitable material, which is not limited herein.
The first mating portion 31 is connected to the trigger 2 and includes a gear 311 disposed on the rotating shaft 22 of the trigger 2, and the gear 311 can rotate with the rotating shaft 22.

The rack locking block 321 includes a rack 322 and a stopper 323, and the rack 322 is engaged with the gear 311 of the first mating portion 31. The extending direction of the rack 322 is parallel to the plane of the rotating direction of the trigger 2, and preferably, the rack 322 and the stopper 323 are integrally formed, so that the rotating motion of the gear 311 is converted into the forward and backward movement of the rack 322 and the stopper 323 in the extending direction of the rack 322, and the up and down rotation of the trigger 2 drives the unlocking structure 3 to move between the unlocking position and the locking position.
The stopper 323 is located below the switch knob 4, and a positioning portion 324 is provided at an end thereof close to the switch knob 4. The positioning portion 324 forms a receiving space 325 for receiving the switch 5, and the switch 5 also defines a distance of the stopper 323 moving forward and backward. The switch knob 4 is located above the housing 1 so that the operator can press the switch knob 4 downward.
Referring to fig. 3, when the second engaging portion 32 moves back and forth, it can be located at an unlocking position and a locking position between the switch knob 4 and the switch 5. When the operator pushes the trigger 2 upward, the second engaging portion 32 is located at the unlocking position, and the switch button 4 can press the switch 5 downward and bring the switch 5 down. When the operator releases the trigger 2, the second engaging portion 32 is located at the lock position, and the unlocking mechanism 3 is caught by the switch knob 4, so that the switch knob 4 cannot press down the switch 5.
Referring to fig. 4 and 5, the switch knob 4 includes a switch knob body 41, a stopper 42 located inside the switch knob body 41 and near the switch 5, and a hollow cylinder 43. The stopper 42 forms a stopper groove 44 capable of receiving the positioning portion 324 in the switch button main body 41. When the second fitting portion 32 is located at the unlocking position, the positioning portion 324 is located right below the stopper groove 44, so that the switch button 4 presses the switch 5 downward; at this time, the positioning portion 324 is received in the stopper groove 44. When the second engaging portion 32 is located at the locking position, the positioning portion 324 and the limiting groove 44 are dislocated from each other, and the positioning portion 324 abuts against the switch button 4 and prevents the switch button 4 from pressing the switch 5 downward.
Referring to fig. 2, the switch 5 is located below the switch button 4, and a solid cylinder 51 is disposed above the switch button 4, and the solid cylinder 51 is accommodated in the hollow cylinder 43 of the switch button 4, so that the switch button 4 drives the solid cylinder 51 to move downward, thereby turning on or off the switch 5.
The operating principle of the switch structure 10 is as follows;
firstly, the trigger 2 is pushed upwards, and the rotating shaft 22 on the trigger 2 drives the gear 311 to rotate; secondly, the gear 311 drives the rack 322 to move, and the rack 322 drives the stop block 323 to move, so that the unlocking structure 3 is located at the unlocking position; then, the switch button 4 is pressed downward to turn on or off the switch 5; then, after the switch button 4 is released, the switch 5 returns to the original position; finally, the trigger 6 is released, the trigger 6 returns to the original position by the spring 251, the gear 311, the rack 322 and the stopper 323 are driven to return to the original position, and the unlocking mechanism 3 returns to the locked position.
The utility model also provides an ice drill (not shown), it includes support 20, is located drive arrangement (not shown) on support 20, by drive arrangement driven transmission (not shown) and by the driven drilling rod of transmission (not shown) and the switch structure 10 of control drive arrangement switching on or switching off power.
