With the advancement of technology and changes in market demand, stone processing drilling machine technology is also constantly developing. Handheld drilling machines are widely used due to their portability and ease of operation.

[0003] However, existing technologies have some problems: current handheld drilling machines lack a stabilizing mechanism during drilling. The stability of drilling depends on the grip strength and skill of the operator on the handle, requiring a certain amount of experience to achieve stable drilling. Moreover, under continuous operation, the operator's arm will quickly become fatigued, leading to a loss of grip on the handle and dropping the machine, which affects the quality of subsequent stone drilling and cannot guarantee the operator's personal safety. Therefore, we propose a drilling machine for stone processing. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a drilling machine for stone processing. By using a foldable first and second adjusting rod around the drill bit and a support plate on the fixed rod to fit against the surface of the stone to be drilled, the drilling machine is stably pressed onto the stone. The operator can then push the main body of the drilling machine toward the stone by gripping the handle with both hands to drill, thereby improving the stability of stone drilling and reducing the difficulty of using the handheld drilling machine.

The first limiting block is fitted against one side of the first adjusting rod. A first spring is provided between the limiting plate and the first adjusting rod, and the limiting plate and the first adjusting rod are elastically connected by the first spring.

[0008] Optionally, a second limiting block is fixedly connected to one end of the first adjusting rod near the second adjusting rod. The second limiting block is L-shaped, and one end of the second limiting block is fitted against one side of the second adjusting rod. A second spring is provided between the first adjusting rod and the second adjusting rod, and the first adjusting rod and the second adjusting rod are elastically connected by the second spring.

[0009] Optionally, one end of the rotating rod is rotatably connected to the second adjusting rod, and the other end of the rotating rod is provided with a locking bolt. The other end of the rotating rod is slidably sleeved on the locking bolt. A threaded hole is correspondingly opened on the first adjusting rod, and the locking bolt is threadedly connected to the inside of the first adjusting rod.

[0010] Optionally, a fixing rod is fixedly connected to the lower end of the limiting plate located on the back of the drilling machine body, and a support plate is fixedly connected to the lower ends of both the fixing rod and the second adjusting rod.

Detailed Implementation

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown in the figure, the present invention provides a drilling machine for stone processing, including a drilling machine body 1, a top plate 2 at the upper end of the drilling machine body 1, an adjusting spring 201 between one end of the drilling machine body 1 and the top plate 2, the drilling machine body 1 and the top plate 2 being elastically connected by the adjusting spring 201, three sets of limiting plates 202 being fixedly connected below the top plate 2, the outer side of the drilling machine body 1 being slidably connected to the limiting plates 202, a first adjusting rod 3 being rotatably connected to the bottom of the limiting plates 202 on both sides of the drilling machine body 1, a second adjusting rod 4 being rotatably connected to one end of the first adjusting rod 3, and a rotating rod 401 being rotatably arranged between the first adjusting rod 3 and the second adjusting rod 4.

[0024] It should be noted that when the operator drills holes in the stone, the first adjusting rod 3 and the second adjusting rod 4 are unfolded. At this time, the first adjusting rod 3 is perpendicular to the main body 1 of the drilling machine, and the second adjusting rod 4 is perpendicular to the first adjusting rod 3. Then, the position between the first adjusting rod 3 and the second adjusting rod 4 is locked to ensure that there will be no loosening during the drilling process, thus ensuring the stability of the drilling. Then, the first adjusting rod 3, the second adjusting rod 4 and the fixing rod 6 are pressed tightly against the stone surface. The switch of the main body 1 of the drilling machine is turned on, and the main body 1 of the drilling machine is pushed towards the stone surface with both hands to drill. The operation is convenient and labor-saving, and the stability during drilling is improved.

[0025] In a preferred embodiment of this application, hand handles 102 are symmetrically fixedly connected to both sides of the drilling machine body 1, and sliders 101 are fixedly connected to both sides and the back of the drilling machine body 1. A limit groove is correspondingly opened on the limiting plate 202, and the drilling machine body 1 and the limiting plate 202 are slidably connected in the limit groove through the sliders 101.

[0026] It should be noted that by firmly grasping the handle 102 with both hands and pushing the drill body 1 towards the stone to drill a hole, the drill body 1 can be easily pushed by sliding between itself and the limiting plate 202.

[0027] In a preferred embodiment of this application, a first limiting block 203 is fixedly connected to one end of the limiting plate 202 near the first adjusting rod 3. The first limiting block 203 is fitted against one side of the first adjusting rod 3. A first spring 301 is provided between the limiting plate 202 and the first adjusting rod 3. The limiting plate 202 and the first adjusting rod 3 are elastically connected by the first spring 301.

[0028] It should be noted that the first limiting block 203 is located at the point where the first adjusting rod 3 and the limiting plate 202 rotate, which acts as a block to prevent the first adjusting rod 3 from rotating excessively and causing the second adjusting rod 4 to be unable to be perpendicular to the stone surface. The first spring 301 pulls the first adjusting rod 3 upward to prevent the first adjusting rod 3 from automatically retracting and causing safety accidents such as pinching hands.

[0029] In a preferred embodiment of this application, a second limiting block 303 is fixedly connected to one end of the first adjusting rod 3 near the second adjusting rod 4. The second limiting block 303 is L-shaped, and one end of the second limiting block 303 is fitted against one side of the second adjusting rod 4. A second spring 403 is provided between the first adjusting rod 3 and the second adjusting rod 4, and the first adjusting rod 3 and the second adjusting rod 4 are elastically connected by the second spring 403.

[0030] It should be noted that the second limiting block 303 is located at the rotation point between the first adjusting rod 3 and the second adjusting rod 4, which restricts and blocks the second adjusting rod 4 to prevent it from rotating excessively. The second spring 403 pulls on the second adjusting rod 4 to prevent it from automatically retracting during the adjustment process.

[0031] In a preferred embodiment of this application, one end of the rotating rod 401 is rotatably connected to the second adjusting rod 4, and the other end of the rotating rod 401 is provided with a locking bolt 302. The other end of the rotating rod 401 is slidably sleeved on the locking bolt 302. A threaded hole is correspondingly opened on the first adjusting rod 3, and the locking bolt 302 is connected to the inside of the first adjusting rod 3 by a thread.

[0032] It should be noted that after the first adjusting rod 3 and the second adjusting rod 4 are pulled into place, their positions are locked by rotating the locking bolt 302, which ensures the stability of the drilling machine body 1 when drilling into the stone.

[0033] In a preferred embodiment of this application, a fixing rod 6 is fixedly connected to the lower end of the limiting plate 202 located on the back of the drilling machine body 1, and a support plate 5 is fixedly connected to the lower ends of both the fixing rod 6 and the second adjusting rod 4.

[0034] It should be noted that by pressing the stone surface with three sets of support plates 5 at multiple points, the stability of the first adjusting rod 3, the second adjusting rod 4 and the fixing rod 6 pressed on the stone surface during the drilling process is ensured.

[0035] It is worth noting that the surface of the support plate 5 can be fitted with an anti-slip sleeve to increase the friction with the stone surface and prevent excessive force from pushing the hand handle 102 during drilling, which could cause the support plate 5 to slip between the support plate 5 and the stone surface.

[0036] In a preferred embodiment of this application, the fixed rod 6 and the second adjusting rod 4 are of equal length, and a lifting handle 402 is fixedly connected to the side of the second adjusting rod 4 that is far apart from each other;

[0037] It should be noted that the fixed rod 6 and the second adjusting rod 4 are of equal length, ensuring that the three sets of support plates 5 are on the same plane and that the three sets of support plates 5 can fit tightly against the stone surface. By lifting the pull handle 402 upward, the second adjusting rod 4 drives the first adjusting rod 3 to rotate outward. The first spring 301 ensures that the first adjusting rod 3 fits against the first limiting block 203, and the second spring 403 ensures that the second adjusting rod 4 fits against the second limiting block 303. Then, by rotating the locking bolt 302, the overall stability during the drilling process is ensured.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
