[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the embodiments, by Figure 1-3 A drilling device for the back cover of a display is provided, comprising a housing 1, a support rod 2 fixedly connected to the top of the housing 1, a pressing plate 3 detachably connected to the top of the support rod 2 by bolts, a drive shaft 4 rotatably connected to the inner side of the housing 1 with one end extending to the outer side of the housing 1, a crank handle 5 snapped onto the drive shaft 4, a tapping drill bit 6 rotatably connected to the inner side of the housing 1, and a transmission mechanism 7 for connecting the drive shaft 4 and the tapping drill bit 6 provided on the inner side of the housing 1.

[0021] With the above settings, press and hold the extrusion plate 3, align the tapping drill bit 6 with the back cover of the display to be drilled, and shake the crank 5 to drive the drive shaft 4 to rotate. The power is transmitted to the tapping drill bit 6 through the transmission mechanism 7, so that the tapping drill bit 6 drills the back cover of the display to be drilled. Compared with moving the back cover of the display to drill, manual drilling is more convenient and faster.

[0022] Reference Figure 1-3 The transmission mechanism 7 includes a drive gear 71, a drive gear 71 fixedly connected to the outer side of the drive shaft 4, a transmission shaft 72 rotatably connected to the inner side of the housing 1, a transmission gear 73 meshing with the drive gear 71 fixedly connected to the outer side of the transmission shaft 72, a transmission bevel gear 74 fixedly connected to the outer side of the transmission shaft 72, and an output bevel gear 75 meshing with the transmission bevel gear 74 fixedly connected to the top of the tapping drill bit 6.

[0023] With the above-mentioned structure, when the crank handle 5 is rotated, it can drive the drive shaft 4 to rotate, which in turn drives the drive gear 71 to rotate. Since the drive gear 71 and the transmission gear 73 mesh with each other, the transmission shaft 72 is driven to rotate. Since the transmission bevel gear 74 and the output bevel gear 75 mesh with each other, the tapping drill bit 6 rotates accordingly.

[0024] Reference Figure 1-3 The right end of the housing 1 is fixedly connected to a handle 8;

[0025] With the above-described structure, gripping the handle 8 makes it easy to drill holes in the back cover of the monitor.

[0026] Reference Figure 1-3 The drive shaft 4 has a slot 9, and the crank handle 5 is threaded with a locking bolt 10 whose end abuts against the slot 9.

[0027] With the above structural design, the end of the drive shaft 4 has two cut surfaces, and the inner side of the crank handle 5 has a snap-fit ​​hole that matches the end of the drive shaft 4. The snap-fit ​​bolt 10 is inserted into the slot 9 to snap the crank handle 5 onto the outside of the drive shaft 4. When the crank handle 5 needs to be removed, simply rotate the snap-fit ​​bolt 10 to disengage it from the slot 9, and the crank handle 5 can be removed.
