Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figures 1 to 6 As shown, a handheld electric glass cutting device includes a housing 1. Inside the housing 1, there are an energy storage chamber 101, a main chamber 103, a secondary chamber 104, and a rotating shaft chamber 105. Inside the main chamber 103, from the energy storage chamber 101 along the direction of the secondary chamber 104, there are a control board 4, a drive device 5, and a gearbox 6 that are fixedly connected to the main chamber 103. The extended end of the drive device 5 is engaged and driven by the gearbox 6. The function of the gearbox 6 is to convert the power output by the drive device 5 into high torque power for subsequent glass cutting. One end of the gearbox 6 extends to the bottom of the shaft housing 105. A shaft hole 1051 is fixedly connected to the middle of the bottom of the shaft housing 105. A lead screw 16 is rotatably connected inside the shaft hole 1051. A bevel gear 17 is fixedly connected to one end of the lead screw 16 near the shaft hole 1051. Inside the shaft housing 105, a bevel gear 18 is rotatably connected to the gearbox 6. The bevel gear 18 meshes with the bevel gear 17. A lifting plate 12 is meshed with the lead screw 16. The lifting plate 12 is slidably connected to the outer casing 1. A first gear 1001 is rotatably connected to the upper part of the lifting plate 12 on the outer side of the outer casing 1. A gear post 10 is fixedly connected to the upper end of the first gear 1001. A third gear 24 is rotatably connected to one side of the lifting plate 12. A second gear 1302 is rotatably connected to one side of the lifting plate 12. Below the second gear 1302, there is an upper pressure plate 13 rotatably connected to the lifting plate 12. A limit post 1301 is fixedly connected to one side of the upper pressure plate 13. The limit post 1301 passes through the lifting plate 12 and is fixedly connected to the second gear 1302. The upper pressure plate 13 can rotate to remain parallel to the lifting plate 12 or perpendicular to the lifting plate 12. When parallel, it can be hidden under the lifting plate 12 for easy storage or for the cutter head 15 to mark lines. When perpendicular, its main function is to separate the glass.

[0027] A drive unit 2 7 is fixedly connected inside the auxiliary compartment 104. A bevel gear 8 is fixedly connected to the extended end of the drive unit 2 7. A gear 901 is provided on one side of the bevel gear 8 and is rotatably connected to the auxiliary compartment 104. A bevel gear 2 9 is fixedly connected to one side of the gear 901. The bevel gear 2 9 meshes with the bevel gear 8 for transmission. The gear 901 meshes with or slides with the gear post 10. Because the gear post 10 can move up and down, the gear 901 is slidably connected to the gear post 10 when the gear post 10 moves up and down. When the gear 901 rotates, it can drive the gear post 10 to rotate. A protective cover 22 is provided on the outside of the gear post 10 and is fixedly connected to the auxiliary compartment 104. One end of the lead screw 16 is rotatably connected to the bottom of the auxiliary compartment 104.

[0028] The first gear 1001 meshes with the third gear 24 for transmission, and the third gear 24 meshes with the second gear 1302 for transmission. A protective cover 11 is fixedly connected above the lifting plate 12, covering the first gear 1001, the second gear 1302, and the third gear 24. The protective cover 11 protects the gears from damage due to foreign objects entering. At the junction of the shaft chamber 105 and the main chamber 103 below the lifting plate 12, a lower pressure plate 14 is fixedly connected. At the end of the lower pressure plate 14 away from the main chamber 103, there is a threaded hole 1401 that is inclined downward at 45°. A cutter head 15 is threaded onto the threaded hole 1401. The 45° angle facilitates the use of the cutter head 15 to score and divide the glass, and the cutter head 15 is a commonly used cutter head on the market, which is easy to replace and has greater versatility. The cross-section of the lower pressure plate 14 in the width direction is a regular trapezoid, and the upper pressure plate 13 is inverted "U" shaped on the opposite side of the lower pressure plate 14. The protruding part of the lower pressure plate 14 fits perfectly with the concave part of the upper pressure plate 13. The advantage of this is that when the upper pressure plate 13 and the lower pressure plate 14 are separated along the glass line, it is easier to separate them.

[0029] A battery 21 is fixedly connected inside the energy storage compartment 101. A limit switch 102 is fixedly connected at the corner where the energy storage compartment 101 connects to the main compartment 103. A control trigger 19 is rotatably connected to the limit switch 102. A matching double-control switch 20 is provided at one end of the control trigger 19. The double-control switch 20 is fixedly connected to the bottom main compartment 103 of the drive device 5. Inserting a finger into the hole of the control trigger 19 and moving it forward and backward can control the forward and reverse rotation of the drive device 5, respectively. If the finger stops in the middle, the motor will not operate.

[0030] A double-control switch 23 is rotatably connected to the side panel of the outer casing 1. A charging interface 2 and a power switch 3 are fixedly connected to the control board 4 on the side away from the drive unit 5. The charging interface 2 and power switch 3 pass through the outer casing 1. The battery 21 can be charged through the charging interface 2, and the power switch 3 can be pressed to turn the device on or off. The control board 4 is electrically connected to the battery 21, drive unit 5, drive unit 7, double-control switch 20, and double-control switch 23 via wires. Double-control switch 20 controls drive unit 5, and double-control switch 23 controls drive unit 7. The function of the control board 4 is to control the power supply, provide overcharge protection for the battery 21, and provide anti-torsion protection for drive unit 5 and drive unit 7.

[0031] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0032] Working process: This utility model, as Figure 1 As shown, hold the outside of the energy storage compartment 101, turn on the power switch 3, and use the cutter head 15 to score the glass. After completion, push the double control switch 23 with your thumb to rotate the drive device 7. The drive device 7 drives the bevel gear 8 to rotate, which in turn drives the bevel gear 9 to rotate. The gear 901 at the bottom of the bevel gear 9 rotates synchronously, driving the gear column 10 to rotate. The first gear 1001 at the bottom of the gear column 10 drives the third gear 24 to rotate, which in turn drives the second gear 1302 to rotate. Under the action of the second gear 1302, the upper pressure plate 13 changes from being parallel to the lifting plate 12 to being vertical. Then place the glass between the upper pressure plate 13 and the lower pressure plate 14, and press down the control trigger 19. The drive device 5 transmits kinetic energy to the gearbox 6 to increase torque, which is then transmitted to the bevel gear 18. The bevel gear 18 drives the bevel gear 17 to rotate, and the lead screw 16 rotates synchronously, causing the lifting plate 12 to descend and squeeze the glass, thus separating the glass. At the moment the glass is split, the control trigger 19 moves upward, causing the lifting plate 12 to rise, and the next operation is performed.

[0033] When the cutter head 15 is reused for marking or is not used, the double control switch 23 is pushed in the reverse direction, causing the drive device 7 to reverse, and the upper pressure plate 13 is kept parallel to the lifting plate 12 again, so as to prevent it from affecting the cutter head 15 when marking, and to protect the upper pressure plate 13.

[0034] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
