[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the flip assembly 8 includes a mounting plate 81, a U-shaped plate 82, a second rotating shaft 83, a crank 84, a sliding shaft 85, a U-shaped slide 88 and a first cylinder 89. The top of the top plate 5 is symmetrically provided with a slide groove. The bottom of the mounting plate 81 is slidably matched with the slide groove on the top of the top plate 5 through a sliding block. A U-shaped plate 82 is provided on the left side of the top of the mounting plate 81. The second rotating shaft 83 is rotatably provided between the front and rear side walls of the U-shaped plate 82. A crank 84 is rotatably provided on the second rotating shaft 83. A straight guide hole is opened on the lower side of the crank 84. The front and rear side walls of the U-shaped plate 82 are both provided with a slotted groove 86. A slotted hole 87 penetrating the side wall is provided at the position of the slotted groove 86 of the U-shaped plate 82. The two slides of the U-shaped slide 88 are slidably installed on the slotted groove 86 of the U-shaped plate 82. A sliding shaft 85 is provided between the U-shaped slides 88. The sliding shaft 85 passes through the slotted hole 87 of the U-shaped plate 82 and the slotted guide hole of the crank 84. A first cylinder 89 is installed on the right side of the mounting plate 81 by bolt connection. The telescopic rod of the first cylinder 89 is connected to the center of the right side wall of the U-shaped slide 88.

[0026] like Figure 1 and Figure 5As shown, the clamping assembly 11 includes an arc-shaped connecting plate 111, a base 112, a fixing block 113, an arc-shaped clamping block 114, a fastening bolt 115 and a second cylinder 116. The second slider 10 is provided with an arc-shaped connecting plate 111, and a base 112 is provided at the lower part of the arc-shaped connecting plate 111. A circular hole for limiting the impact drill from sliding downward is provided at the bottom of the base 112. The front side of the arc-shaped connecting plate 111 is symmetrically provided with fixing blocks 113, and threaded holes are provided on the fixing blocks 113. The arc-shaped clamping block 114 is installed on the fixing block 113 at the same horizontal position by a fastening bolt 115. A second cylinder 116 is installed at the bottom of the track groove of the second slide rail 9, and the telescopic rod of the second cylinder 116 is connected to the arc-shaped connecting plate 111.

[0027] When the device is needed, the staff first fits the box 1 on the top of the square stone, and then starts the motor 78. The motor 78 drives the first rotating shaft 72 to rotate through the pulley, and then the screw rod 73 rotates to drive the clamping plate 75 to move towards each other, thereby clamping and fixing the two sides of the square stone, and then controlling the motor 78 to close. Then the first cylinder 89 is controlled to extend, and the first cylinder 89 drives the U-shaped slide 88 to move left along the straight slide groove 86, and the U-shaped slide 88 drives the slide shaft 85 to move left along the straight hole 87, and then the slide shaft 85 squeezes the crank 84, and the crank 84 rotates 90° clockwise around the second rotating shaft 83, and the second slide rail 9, the second slide block 10 and the clamping assembly 11 rotate 90°. At this time, the staff puts the impact drill card on the arc connecting plate 111, and then aligns the arc clamp block 114 with the threaded hole of the fixing block 113, and then fixes the arc clamp block 114 by tightening bolts 115, thereby completing the fixation of the impact drill. Then, by controlling the first cylinder 89 to shrink and reset, the crank 84 rotates 90° counterclockwise around the second rotating shaft 83, the second slide rail 9, the second slider 10 and the clamping assembly 11 rotate 90° and reset. At this time, the impact drill is vertically downward, and the staff moves the mounting plate 81 forward and backward as needed to adjust the position of the drill bit. When drilling is required, the staff controls the second cylinder 116 to work, the second cylinder 116 shortens and drives the second slider 10 to move downward, and then the clamping assembly 11 drives the impact drill to move downward to drill the stone. After the drilling is completed, the second cylinder 116 is controlled to work. The second cylinder 116 extends, and then the clamping assembly 11 drives the impact drill to move upward and reset, and then pushes the top plate 5 to the left. The top plate 5 moves to the left along the first slide rail 3 through the first slider 4, driving the impact drill to move to the next drilling position, and repeating the previous drilling operation. The device has a simple structure, can stabilize the impact drill, and realize straight downward drilling. Through the fixation of the clamping assembly 7 and the setting of the first slide rail 3 and the first slider 4, the impact drill can be moved along a straight line, completing the precise positioning of multiple hole positions that are difficult to be located on the same horizontal line, which is beneficial to subsequent installation.

[0028] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 6 As shown, a cooling assembly 12 is also included, and the cooling assembly 12 includes a guide sleeve 121, a protective block 122, a nozzle 123 and a hose 124. The protective block 122 is symmetrically arranged on the left side of the movable plate 6, and the nozzle 123 is obliquely embedded on the protective block 122. Two guide sleeves 121 are symmetrically arranged on the front and rear side walls of the mounting plate 81, and the nozzle 123 is connected to the hose 124, and the hose 124 passes through the guide sleeve 121 on the adjacent side. Since the two nozzles 123 face the drill bit position of the impact drill, the external pump body and pipeline are connected to the hose 124, and water can be pumped into the drill bit being processed for impact cooling.

[0029] like Figure 1 and Figure 2 As shown, it also includes a limiting sleeve 13 and an insertion rod 14. The limiting sleeve 13 is symmetrically arranged on the left side wall of the baffle 2. The insertion rod 14 is slidably arranged in the limiting sleeve 13. The insertion rod 14 is inserted into the socket on the right side of the top of the movable plate 6. When the movable plate 6 needs to be moved, the insertion rod 14 can be pulled out upward from the limiting sleeve 13, and then the insertion rod 14 no longer limits the movable plate 6. The setting of the limiting sleeve 13 and the insertion rod 14 can prevent the movable plate 6 from moving when the device is moved.
