[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] As shown in Figures 1-3, this utility model provides a technical solution: a handheld pneumatic anchor drill, including a drill housing 1. A drill 2 is firmly fixedly installed on the bottom of the inner wall of the drill housing 1. The rear end of the drill 2 is connected to a drill rod 3 for drilling operations. A fixed cylinder 4 is provided on the top of the outer surface of the drill housing 1, and an arc-shaped abutment plate 5 is also provided. The design of the arc-shaped abutment plate 5 can better fit the user's hand, increasing the comfort and stability of holding. A rectangular positioning block 6 is installed on the outer side of the arc-shaped abutment plate 5. A slidable elliptical sliding column 7 is provided inside the rectangular positioning block 6. A pressing cross plate 8 is fixedly installed on the outer side of the elliptical sliding column 7. This structural design allows the elliptical sliding column 7 to drive the pressing cross plate 8 to move when sliding, realizing a specific function. The lower surface of the elliptical sliding column 7 is fixed. A fixed bracket 9 is installed, and a rotatable linkage rod 10 is provided at the bottom of the fixed bracket 9. The bottom of the linkage rod 10 is connected to a rotatable pull bracket 11. By pulling the bracket 11, the linkage rod 10 can be rotated, thereby causing the fixed bracket 9 and the elliptical sliding column 7 to produce corresponding displacement. A U-shaped positioning rod 12 is inserted inside the rectangular positioning block 6, which passes through the elliptical sliding column 7. Its function is to position the elliptical sliding column 7 after it has moved to the appropriate position, ensuring the stability of the entire structure. A T-shaped handle 13 is fixedly installed on the upper surface of the rectangular positioning block 6. The T-shaped handle 13 is designed to be easy for users to grip, and its outer surface is provided with an anti-slip layer. The outer surface of the anti-slip layer is evenly provided with friction anti-slip texture, which further improves the stability of the user's grip and effectively prevents the hand from slipping during use.

[0020] Specifically, as shown in Figures 1 and 2, the elliptical sliding column 7 has a positioning hole inside. The size of the positioning hole is precisely matched with the size of the U-shaped positioning rod 12, which can ensure that the U-shaped positioning rod 12 is accurately inserted and achieves reliable positioning.

[0021] Specifically, as shown in Figure 3, the fixed cylinder 4 has an installation hole inside, and the inner side of the extrusion plate 8 is fixedly installed with an installation cylinder. The installation hole matches the installation cylinder. When the extrusion plate 8 moves, the installation cylinder can be smoothly inserted into the installation hole of the fixed cylinder 4 to fix the T-shaped handle 13. There are two sets of linkage rods 10, and the length of the two sets of linkage rods 10 is 450 mm. This length design can ensure the stability of the structure while ensuring that the operation of pulling the bracket 11 can be effectively transmitted to the elliptical sliding column 7 to achieve precise control. The outer side of the arc-shaped abutment plate 5 has an elliptical through hole, and the elliptical sliding column 7 slides inside the elliptical through hole. This design not only restricts the movement trajectory of the elliptical sliding column 7, but also ensures that it can slide smoothly, providing a guarantee for the normal operation of the entire structure.

[0022] The working principle of this utility model is as follows:

[0023] S1. When the drilling rig 2 needs to be used, first place the arc-shaped abutment plate 5 against the surface of the drilling rig housing 1, control the pulling bracket 11 to drive the linkage rod 10 to move, the linkage rod 10 to drive the fixed bracket 9 to move, the fixed bracket 9 to drive the elliptical sliding column 7 to move, and the elliptical sliding column 7 to drive the pressing cross plate 8 to be inserted into the interior of the fixed cylinder 4 to fix the T-shaped handle 13.

[0024] S2. Then, the U-shaped positioning rod 12 is inserted into the elliptical sliding column 7 through the inside of the rectangular positioning block 6 of the elliptical sliding column for positioning, which ensures the stability of the positioning of the T-shaped handle 13.

[0025] In summary, this handheld pneumatic anchor drill, by setting up a pulling bracket 11 and a linkage rod 10 to drive the fixed bracket 9 and the elliptical sliding column 7 to push the extrusion plate 8 into the interior of the fixed cylinder 4, achieves the fixing operation of the T-shaped handle 13. This results in a better fixing effect on the T-shaped handle 13, helps to better ensure the stability of the fixing of the T-shaped handle 13, and makes the use of the T-shaped handle 13 simpler and more convenient, helping people to use it better.
