DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figures 1 to 7The utility model provides a technical solution: a switch sliding structure of an electric circular saw, comprising a fixed base plate 1, on which a driving main housing 2 and a circular saw main housing 3 which are connected to each other and fixedly connected are installed, and the two side surfaces of the driving main housing 2 are connected with switch sliding buttons 7 in a through-limited sliding manner, and a push rod 11 is fixedly connected to one side surface of the switch sliding button 7, and a concave V-shaped pushing portion 12 is fixedly connected to the end of the push rod 11 away from the switch sliding button 7, and a return column 13 is abutted and connected to the central concave part of the V-shaped pushing portion 12, and a trigger element 16 is fixedly installed on one side of the driving main housing 2 away from and on the same horizontal line as the push rod 11, and a touch sensing plate 17 for performing contact switch operation is connected to one side of the touch sensing plate 17, and the touch sensing plate The other side surface of 17 is fixedly connected to the other end of the return column 13, and the return column 13 is fixedly sleeved with a sliding sleeve 14 on the outside near the V-shaped pushing part 12, and the inside of the driving main shell 2 is fixedly installed with a first limit frame plate 9 and a second limit frame plate 10 for limiting the sliding of the sliding sleeve 14 and the return column 13 on one side near the trigger element 16, a spring 15 is welded between the sliding sleeve 14 and the second limit frame plate 10, and the spring 15 is wound around the outside of the return column 13, and a lighting lamp 20 is fixedly installed on the surface of one side of the driving main shell 2 near the main shell 3 of the circular saw, and a cable 18 is fixedly connected between the trigger element 16 and the lighting lamp 20, and a power block 8 that only supplies power to the lighting lamp 20 is fixedly installed on the inside of the driving main shell 2 near the switch slider 7.

[0026] More specifically, in this embodiment, the operator can slide the switch slider 7 in the direction of the trigger element 16, and the switch slider 7 drives the V-shaped push portion 12 of the push rod 11 to push the return column 13 to slide in the direction of the trigger element 16, and the concave V-shaped push portion 12 is more conducive to pushing the return column 13 until the return column 13 pushes the touch sensing plate 17 to contact the trigger element 16, so that the trigger element 16 generates a touch conductive induction, and the lighting lamp 20 is started to illuminate through the cable 18. After that, the operator only needs to release the switch. When pressure is applied to the switch slider 7, the spring 15 between the sliding sleeve 14 and the second limit frame plate 10 will drive the return column 13 and the push rod 11 to slide back in the opposite direction, and the touch sensing plate 17 will be disconnected from the trigger element 16, and the lighting lamp 20 will be extinguished as the disconnection returns to the original position, thereby ensuring the flexible use of the switch sliding structure for the lighting lamp. During this process, the sliding sleeve 14 and the return column 13 slide in the first limit frame plate 9 and the second limit frame plate 10 respectively to ensure the accuracy of the switch sliding.

[0027] The use of a power block 8 that is fixedly installed inside the main driving shell 2 and only supplies power to the lighting lamp 20 effectively ensures that the power block 8 can provide power support for the lighting lamp 20 alone when the electric circular saw is not started, thereby improving the safety of using the lighting lamp 20 when the electric circular saw is not used.

[0028] Furthermore, a hand grip 4 is fixedly connected to the upper end of the driving main shell 2, one end of the hand grip 4 is fixedly installed with a battery socket 5 for plugging in a battery pack, and a driving button 6 is fixedly installed on the lower surface of one side of the hand grip 4.

[0029] A motor 21 is fixedly installed inside the driving main shell 2, and the output shaft of the motor 21 passes through the interior of the circular saw main shell 3 and is fixedly connected to a bevel gear shaft 22. The bevel wheel of the bevel gear shaft 22 is meshedly connected to a bevel gear disc 23, and the bevel gear disc 23 is limited and rotatably installed inside the circular saw main shell 3. A rotating connecting shaft 24 is fixedly sleeved inside the bevel gear disc 23, and a circular saw body 26 is fixedly sleeved outside the rotating connecting shaft 24.

A lower gear protective shell 25 is limited and rotatably sleeved inside the driving main shell 2, and the lower gear protective shell 25 is wrapped around the outside of the circular saw body 26 for limiting rotation. A dust suction connector 28 is fixedly installed on one side of the circular saw main shell 3 for convenient connection of a dust suction device for dust suction purposes.

[0030] It is worth mentioning that the operator can insert the battery pack into the battery socket 5 in advance to provide power support, and enhance the sawing stability during sawing by holding the grip 4, and then start the motor 21 by pressing the drive button 6. The output shaft of the motor 21 drives the bevel gear shaft 22 to rotate, and the bevel gear shaft 22 engages to drive the bevel gear plate 23 to rotate stably under the drive, and the bevel gear plate 23 drives the rotating connecting shaft 24 to rotate synchronously, and the rotating connecting shaft 24 finally drives the circular saw body 26 to perform sawing operation. During the sawing process, the dust suction joint 28 can facilitate the dust removal operation.
