[0013] Figure 1 It is a structural schematic diagram of the handheld top plate drilling device of the utility model.

[0014] In the figure, 1-drilling machine; 2-drill rod; 3-hopper; 4-material guide pipe; 5-ash collecting box; 6-spring; 7-threaded sleeve; 8-bottom support rod; 9-handle rod; 10-ash collecting device; 11-height adjustment component. DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] like Figure 1 The handheld top plate drilling device shown includes: a drill rig 1, a drill rod 2, a dust collecting device 10, a height adjustment assembly 11 and a bottom support rod 8; the drill rod 2 is sequentially connected with the drill rig 1 and the dust collecting device 10 along its length direction from top to bottom; an opening is provided at the lower end of the drill rod 2, and a vertical channel connected to the opening at the lower end of the drill rod 2 is provided inside the drill rod 2; the drill bit of the drill rig 1 is arranged upward; the upper end of the bottom support rod 8 extends into the vertical channel through the opening, and the bottom support rod 8 cooperates with the drill rod 2 in the vertical direction. A base is provided at the lower end of the bottom support rod 8, and the base contacts the ground. By manually adjusting the height of the drill rod 2, the drill rig 1 contacts the top plate, thereby realizing the drilling operation of the top plate. The dust collecting device 10 is used to receive the dust generated by drilling.

[0017] The height adjustment assembly 11 includes a threaded sleeve 7 , a spring 6 and a handle bar 9 .

[0018] The bottom support rod 8 is provided with an external thread, and the threaded sleeve 7 is sleeved on the bottom support rod 8 and matched with its thread. The threaded sleeve 7 is located below the drill rod 2, and the outer diameter of the threaded sleeve 7 is larger than the aperture of the opening at the lower end of the drill rod 2. By rotating the threaded sleeve 7, the lower end of the drill rod 2 is brought into contact with the upper end of the threaded sleeve 7, so that the height of the threaded sleeve 7 limits the height of the drill rod 2. According to the floor height, the height of the drill rig 1 is limited by adjusting the height of the threaded sleeve 7. When drilling a hole in the top plate, after starting the drill rig 1, the drill rod 2 can be lifted up by hand.

[0019] The spring 6 is sleeved on the bottom support rod 8 and is located between the drill rod 2 and the threaded sleeve 7. The spring 6 plays a role of buffering and shock absorption. The vibration generated by the drilling rig 1 is transmitted to the spring 6 and absorbed by the spring 6, and will not be transmitted too much to the ground through the drill rod 2. In addition, the spring 6 prevents the drill rod 2 from directly contacting the threaded sleeve 7, and the threaded sleeve 7 will not be directly impacted when the drill rod 2 descends. When the threaded sleeve 7 is rotated to raise the threaded sleeve 7, the threaded sleeve 7 squeezes the spring 6, and the spring 6 is compressed. As the spring 6 is compressed, the threaded sleeve 7 is continuously rotated until the drill rod 2 is raised, and the spring 6 remains compressed. As the drilling rig 1 works, the spring 6 gradually releases energy, and there is no need to always lift the drill rod 2 or jack up the drill rod 2, so the drilling work is more labor-saving.

[0020] The handle bar 9 is connected to the threaded sleeve 7, one end of the handle bar 9 is fixed to the threaded sleeve 7, and the handle bar 9 extends in a direction away from the threaded sleeve 7. The handle bar 9 is rotated circumferentially along the threaded sleeve 7, and the threaded sleeve 7 can be driven to rotate on the bottom support rod 8 with less effort. When the threaded sleeve 7 is rotated to descend, the drill rod 2 follows and descends.

[0021] The ash receiving device 10 includes a hopper 3, a guide pipe 4 and an ash collecting box 5; the hopper 3 includes a bottom plate and a side plate arranged at the upper end of the bottom plate along the circumference of the bottom plate; the drill rod 2 passes through the bottom plate, and the bottom plate is also provided with a discharge hole; the ash collecting box 5 is connected to the drill rod 2 and is located below the discharge hole. The upper end of the guide pipe 4 is connected to the discharge hole, and the lower end of the guide pipe 4 is located in the ash collecting box 5. The dust generated when the drilling rig 1 drills the top plate enters the hopper 3, and then enters the ash collecting box 5 through the guide pipe 4. The ash receiving device 10 is fixed to the drill rod 2 as a whole, and rises and falls synchronously with the drill rod 2.

[0022] The handheld roof drilling device of the utility model can perform roof drilling operations on the ground without the need for high-altitude operations, thereby reducing the risk of falling from high places at the construction site.

[0023] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
