A cleaning component for cleaning the inner wall of the transparent shell 9 is arranged in the circular hole. The cleaning component is rotatably mounted on the outer wall of the hollow tube 4. A locking mechanism is arranged on the outer wall of the hollow tube 4. The locking mechanism is used to lock the lifting frame 7 to lock the transparent shell 9 so that the drill bit 5 is exposed. The lifting frame 7 includes four sliding rods 72 connected to the top of the outer cover 6 in an interval sliding manner, an annular plate I71 connected to the top of the four sliding rods 72, and an annular plate II73 connected to the bottom of the four sliding rods 72. The annular plate I71 is located above the outer cover 6, and the annular plate II73 is located in the outer cover 6. The transparent shell 9 is connected in the annular plate II73, and the bottom ends of the four springs I8 are connected to the top of the annular plate II73.

[0041] See also Figure 3-Figure 4 The cleaning component includes a rotating member movably arranged in a circular hole at the top of the transparent shell 9, the rotating member is rotatably installed on the outer wall of the hollow tube 4, two brushes 104 are symmetrically connected to the rotating member, and a ball 105 is connected in the circular hole. The rotating member includes a sleeve 101 placed in the circular hole at the top of the transparent shell 9 and two connecting plates 103 symmetrically connected to the bottom of the sleeve 101, the two brushes 104 are respectively connected to the bottom of the two connecting plates 103, the sleeve 101 is rotatably connected to the outer wall of the hollow tube 4, and a threaded groove 102 cooperating with the ball 105 is opened on the outer wall of the sleeve 101.

[0042] See also Figure 5The locking mechanism includes a shell 111 connected to the outer wall of the hollow tube 4, the shell 111 is located above the outer cover 6, and a locking frame for clamping the annular plate I71 is slidably connected to the left side of the shell 111, and a spring II 114 is connected between the locking frame and the shell 111. The locking frame includes a cross bar 112 slidably connected to the left side of the shell 111, a wedge-shaped block 113 connected to the left end of the cross bar 112, and a push block 115 connected to the right side of the top of the wedge-shaped block 113. The spring II 114 is connected between the wedge-shaped block 113 and the shell 111, and the bottom of the wedge-shaped block 113 is an inclined surface.

[0043] Initially, the wedge-shaped block 113 clamps the annular plate Ⅰ71, the spring Ⅰ8 is in a compressed state, the transparent shell 9 does not completely cover the drill bit 5, and the drill bit 5 is exposed outside the transparent shell 9. In this way, the device can expose the drill bit 5 before drilling, so that the area of ​​the cement prefabricated product that needs to be drilled can be easily aligned with the drill bit 5, thereby improving the accuracy of drilling. Controlling the operation of the electric slide rail 2 can enable the motor 3 to drive the hollow tube 4 and the drill bit 5 to move reciprocatingly downward and upward. The motor 3 drives the drill bit 5 to move downward and rotate to drill holes in the cement prefabricated product. When the hollow tube 4 moves downward, the push block 115 is manually moved with the wedge-shaped block 113 toward the direction close to the shell 111 to loosen the annular plate I71, and the spring II114 is compressed accordingly. Subsequently, under the resetting action of the compressed spring I8, the annular plate II73 can drive the transparent shell 9 to move downward to completely cover the drill bit 5. In this way, the device can cover the drill bit 5 for protection when drilling, so as to block the fragments generated during drilling in the transparent shell 9 to prevent the cement prefabricated product fragments from splashing to the user. The annular plate II 73 moves downward and drives the annular plate I 71 downward through the slide bar 72. When the annular plate I 71 moves down to the lower side of the wedge-shaped block 113, the push block 115 is released. Under the resetting action of the compressed spring II 114, the wedge-shaped block 113 can be moved and reset in the direction away from the shell 111. The transparent shell 9 moves downward and drives the ball 105 thereon to move downward along the thread groove 102 on the sleeve 101. In this way, the sleeve 101 can be rotated through the cooperation of the ball 105 and the thread groove 102. The rotation of the sleeve 101 drives the brush 104 to rotate through the connecting plate 103. The rotation of the brush 104 can clean the impurities on the inner wall of the transparent shell 9. In this way, the present application can automatically clean the impurities on the inner wall of the transparent shell 9 before punching, thereby preventing the impurities from staying on the inner wall of the transparent shell 9 and affecting subsequent use.The hollow tube 4 moves downward, driving the outer cover 6, spring I8, annular plate I71, slide bar 72, annular plate II73, transparent shell 9, shell 111, cross bar 112, wedge block 113, spring II114 and push block 115 to move downward. When the transparent shell 9 moves downward to contact the cement preform, the transparent shell 9 cannot move downward further, so that the annular plate I71, slide bar 72 and annular plate II73 cannot move downward further, so that the outer cover 6 continues to move downward to compress the spring I8, and the wedge block 113 continues to move downward to contact the annular plate I71, and the annular plate I71 squeezes the inclined surface at the bottom of the wedge block 113, so that the wedge block 113 moves toward the shell 111, and the spring II114 is compressed accordingly. When the wedge block 113 moves downward, the spring I8 is compressed. After reaching the lower side of the annular plate I 71, under the restoring action of the spring II 114, the wedge-shaped clamping block 113 can be moved in the direction away from the shell 111 to reset and clamp the annular plate I 71 again, so that when the hollow tube 4 moves upward with the outer cover 6, the shell 111, the cross bar 112, the wedge-shaped clamping block 113, the spring II 114 and the push block 115, the annular plate I 71 is pushed upward synchronously by the wedge-shaped clamping block 113, so that the sliding rod 72, the annular plate II 73 and the transparent shell 9 can be moved upward synchronously with the outer cover 6, the spring I 8 remains in a compressed state, the transparent shell 9 remains in a state of not completely covering the drill bit 5, and the drill bit 5 remains exposed outside the transparent shell 9, so that the area where the next cement prefabricated product needs to be drilled can be easily aligned with the drill bit 5. When the transparent shell 9 and the ball 105 thereon cannot move further downward, the hollow tube 4 drives the sleeve 101 to move further downward, and the cooperation between the ball 105 and the threaded groove 102 can make the sleeve 101 rotate as it continues to move downward, so that the brush 104 can continue to move downward and rotate to clean the inner wall of the transparent shell 9. At this time, the cement prefabricated product is punched. In this way, the device can automatically clean the impurities on the inner wall of the transparent shell 9 while punching, and can also automatically clean the impurities on the inner wall of the transparent shell 9 before punching, thereby ensuring that the impurities on the inner wall of the transparent shell 9 are cleaned, thereby improving the cleaning effect.

[0044] See also Figure 8-Figure 9, and also includes an unlocking mechanism for driving the wedge-shaped block 113 to move and loosen the annular plate I71, the unlocking mechanism includes two sliding sleeves 131 symmetrically connected to the outer wall of the outer cover 6, a lifting rod 132 slidably connected in the two sliding sleeves 131, and a spring III 133 connected between the lifting rod 132 and the lower sliding sleeve 131, the bottom end of the lifting rod 132 is lower than the bottom end of the drill bit 5, the top end of the lifting rod 132 is connected to a pushing block 134, and the left side of the outer wall of the shell 111 is connected to a connecting block 135 A movable rod 136 is slidably connected to the connecting block 135, a chuck 138 is connected to the middle of the outer wall of the movable rod 136, the chuck 138 is engaged with the push block 115, the left end of the movable rod 136 is connected to a movable block 137, a wedge block 139 is rotatably connected inside the movable block 137, a torsion spring is connected between the wedge block 139 and the movable block 137, the wedge block 139 is in contact with the push block 134, the bottom of the wedge block 139 is an inclined surface, and the top of the wedge block 139 is in contact with the top inside the movable block 137.

[0045] The outer cover 6 moves downward, driving the sliding sleeve 131, the lifting rod 132, the spring III 133 and the pushing block 134 to move downward. Since the bottom end of the lifting rod 132 is lower than the bottom end of the drill bit 5, the lifting rod 132 contacts the cement prefabricated product before the drill bit 5. After the lifting rod 132 contacts the cement prefabricated product, the lifting rod 132 and the pushing block 134 cannot move downward further, so that the sliding sleeve 131 continues to compress the spring III 133 downward. At this time, the housing 111 drives the wedge-shaped block 113, the pushing block 115, the connecting block 135, the movable rod 136, the movable block 137, the chuck 138 and the wedge block 139 to continue to move downward. Since the top of the wedge block 139 contacts the top of the movable block 137, the wedge block 139 cannot rotate upward, so that the wedge block 1 39 continues to move downward and is squeezed by the pushing block 134. The pushing block 134 squeezes the inclined surface at the bottom of the wedge block 139, so that the wedge block 139 moves toward the shell 111, so that the movable block 137 pushes the movable rod 136 with the chuck 138 to move toward the shell 111. The chuck 138 moves toward the shell 111 and pushes the pushing block 115 with the wedge block 113 to move toward the shell 111 to release the annular plate Ⅰ71. In this way, the annular plate Ⅰ71 can be automatically unlocked, so there is no need to manually move the pushing block 115 with the wedge block 113 toward the shell 111 to release the annular plate Ⅰ71, thereby improving the degree of automation, reducing manual operations, and improving work efficiency. The wedge block 113 moves in the direction close to the shell 111 and compresses the spring II 114. When the wedge block 139 moves down and passes over the pushing block 134, under the restoring action of the spring II 114, the wedge block 113 can move and reset with the pushing block 115 in the direction away from the shell 111. The pushing block 115 moves and resets in the direction away from the shell 111 and pushes the chuck 138 and the movable rod 136 to move and reset in the direction away from the shell 111, so that the movable block 137 can move and reset with the wedge block 139 in the direction away from the shell 111. When the wedge block 139 moves up and contacts with the pushing block 134, the wedge block 139 continues to move up and is squeezed and rotated downward by the pushing block 134, and the torsion spring is compressed accordingly, so that the wedge block 113 will not move to loosen the annular plate I71. When the wedge block 139 moves up and passes over the pushing block 134, the wedge block 139 can be rotated upward and reset under the restoring action of the torsion spring.

[0047] The rotation of the brush 104 will bring it into contact with the annular scraper 123, and the annular scraper 123 can scrape off the impurities on the brush 104, so that the impurities on the brush 104 can be cleaned to prevent the impurities from remaining on the brush 104. The rotation of the sleeve 101 drives the ring gear 125 to rotate through the annular rod frame 124, and the transmission of the ring gear 125 and the gear 126 can make the rotating rod 122 rotate. The rotation of the rotating rod 122 drives the annular scraper 123 to rotate. The rotation of the annular scraper 123 can quickly scrape off the impurities on the brush 104, thereby improving the cleaning efficiency and effect.

[0049] Clean water is injected into the water storage barrel 141, and the water pump 142 is controlled to work during drilling. The water pump 142 works to transport the clean water in the water storage barrel 141 to the arc-shaped nozzle 145 through the water pumping pipe 143 and the infusion pipe 144, and the clean water is sprayed onto the inner wall of the transparent shell 9 through the arc-shaped nozzle 145 to rinse the inner wall of the transparent shell 9. In this way, the inner wall of the transparent shell 9 can be cleaned more thoroughly, and spraying water during drilling can reduce dust to prevent dust from floating around.

[0050] See also Fig.12 , and also includes a limiting mechanism, which includes a guide rod 154 connected to the left side of the top of the support 1, two clamping plates 153 symmetrically slidably connected to the guide rod 154, and two screws 151 respectively threadedly connected to the right sides of the two clamping plates 153. The screws 151 are rotatably installed on the right side of the top of the support 1, and the ends of the two screws 151 facing away from each other are connected to the steering wheel 152.

[0051] The steering wheel 152 is turned to rotate the screw 151. The rotation of the screw 151 can move the clamping plate 153 toward the direction close to the cement prefabricated product. In this way, the two clamping plates 153 cooperate to clamp and fix the cement prefabricated product, thereby preventing the displacement of the cement prefabricated product from affecting the drilling, thereby ensuring that the cement prefabricated product is accurately drilled. When the drilled cement prefabricated product is to be taken away, the steering wheel 152 is reversed to rotate the screw 151 in the opposite direction. The screw 151 rotates in the opposite direction to move the clamping plate 153 away from the cement prefabricated product to loosen the cement prefabricated product.
