The invention relates to a hole opening device, in particular to a tile hole opening device for building construction. The technical problem is how to provide a ceramic tile hole opening device for building construction that does not need to break the tile when cutting a circle on the tile, the cut circle is relatively smooth, and the cutting is convenient and the safety factor is high. The ceramic tile opening device for building construction includes an L-shaped plate, supporting legs and the like; four supporting legs are installed at the bottom of the L-shaped plate. The present invention adjusts the contact state between the protrusion and the second slider by rotating the annular disk, thereby completing the adjustment of the position of the carving knife, and then adjusting the diameter of the tile engraving circle, and at the same time, it can also be adjusted through the cooperation of the clamping block and the groove. The position of the board is placed, so as to achieve the rounding of different parts of the tiles, and the rubber block can be used to knock the rounded parts of the tiles by pulling the handle, thereby knocking off the rounded parts of the tiles.

The invention relates to a wiping mechanism. According to the wiping mechanism, a connecting board moves along a sliding rail under the driving of a servo motor and the rotation of a ball screw, finally a compressing mechanism is driven to move to a required position along the sliding rail, and the whole process is achieved through two times of wiping and one time of blow-cleaning; firstly, a dust-free cloth belt is used for wiping with ethyl alcohol, a wet-rubbing cylinder drives a wet-rubbing press board to press downwards, and the wet-rubbing press board is soaked in ethyl alcohol while pressing downwards to enable defective gum on a PCBA golden finger to be soaked; meanwhile, the servo motor moves back and forth three times to remove the defective gum completely; then, the dust-free cloth belt is used for wiping three times without ethyl alcohol to remove ethyl alcohol and defective gum; finally, blowing is conducted, and the motor moves at a low speed at the moment to blow residual ethyl alcohol and chippings away. The wiping mechanism replaces the manual PCBA golden finger wiping method in the electronic industry. By the adoption of the wiping mechanism, different working platforms can be used for different products, and adaptability is high; the dust-free cloth belt is convenient to fix and use, and time and labor are saved; safety and efficiency are improved, thorough wiping is achieved, and manufacturing cost and labor cost are reduced greatly.

The invention relates to the technical field of camping tents, and discloses a camping tent fixed foot that is labor-saving and reliable to install, and includes a housing, the top of the housing is fixedly connected with a gear bin, and a power gear is plugged into the inside of the gear bin , the top of the power gear is fixedly connected with a rocker, the outer wall of the power gear is meshed with a transmission gear, the outer wall of the transmission gear is meshed with a rotating shaft, the inner wall of the housing is fixedly connected with a fixed plate, and the fixed plate A guide rail is provided on the front of the guide rail, and a slide block is slidably connected to the inside of the guide rail. The fixed foot of the camping tent is labor-saving and reliable, and the driving rod is driven to rotate through the rotating shaft. The slider slidably connected in the guide rail moves along the guide rail under the drive of the driving rod, and the fixed rod fixedly connected to the right end of the slider is inserted into the soil. Increase the contact area between the column foot and the soil, increase the adhesion of the column foot, and make the tent more securely fixed.

The invention discloses a house wall surface and floor connecting structure. The connecting structure comprises a floor, a second wall surface and hinges used for connecting the floor and the second wall surface, the second wall surface can rotate through the hinges, a plurality of second grooves are formed in the surface of the floor, hinge seats are fixed into the second grooves, a plurality of seventh grooves are formed in the side, close to the floor, of the second wall surface, one ends of the hinges are fixed to the hinge seats, and the other ends of the hinges are fixed into the seventh grooves. The second wall surface and the floor are hinged through the hinges, connection is simple and reliable, folding and unfolding of the second wall surface are facilitated, the structure is simple and reasonable, and practicability is good.

The invention provides a vertical cable laying support and fixing device for wind power generation, which relates to the technical field of wind power generation, and solves the problem that when the traditional wind power generation cable is used in the support and fixing device, two clips are clamped on the outside of the cable by means of bolt fixing. , requires the staff to hold a wrench and twist the bolts to fix the cable. The process is relatively cumbersome, including the assembly base and the gear block; the front side of the assembly base is connected to a movable seat, and the front side of the movable seat is connected to the support seat; The tooth block is connected to the top of the front side of the movable seat, and the bottom end of the tooth block is connected to the top end of the support seat; a movable clamp rod is connected inside the support seat, and the two ends of the movable clamp rod are respectively connected to the drive frame through connecting rods; The front end of the frame moves down, the rear end of the drive frame drives the connecting rod to lift up, and the connecting rod drives the left and right ends of the movable clamping rod to move forward synchronously, clamping the fixed clamping rod and the movable clamping rod on the front and rear sides of the cable, making it easier to clamp and fix the cable fast.
