The utility model provides a basement terrace crack control device, which belongs to the technical field of terrace joint filling and comprises a handheld seat, a bearing sleeve is fixedly connected onto the handheld seat, a mounting pipe is fixedly connected into the bearing sleeve, a trowelling mechanism is arranged on the mounting pipe, a slurry storage cylinder is arranged in the mounting pipe, and the slurry storage cylinder is fixedly connected with the bearing sleeve. A grouting head is fixedly connected to the outer end of the slurry storage cylinder, a limiting ring is fixedly connected to the slurry storage cylinder, and a threaded block is fixedly connected to the outer end of the mounting pipe. Through the arrangement of the handheld seat, the slurry storage cylinder, the grouting head, the rack, the piston, the rotating shaft, the gear, the worm gear, the fixed seat, the motor and the worm, a constructor can hold the handheld seat by hand to enable the grouting head to uniformly grout into a floor crack, so that the crack is fully filled with slurry, automatic and uniform pushing and grouting are realized, the operation is simple, convenient and flexible, the complicated crack can be conveniently dealt with, and the construction efficiency is improved. The efficiency of crack filling control is improved, and the problems that in the prior art, grouting uniformity is poor, and construction efficiency is low are solved.

This utility model discloses a mattress nailing machine, including a nailing machine body. A pin is fixedly installed at the bottom of the nailing machine body. A rotating frame is fixedly installed on the lower part of one side of the nailing machine body. A fixed baffle is fixedly installed on one side of the nailing machine body, located at the bottom of the rotating frame. A cushioning pad is fixedly installed on the upper side of the fixed baffle. A first rotating shaft is rotatably installed in the middle of the rotating frame. A support arm is fixedly installed in the middle of the surface of the first rotating shaft. Torsion springs are sleeved on both ends of the surface of the first rotating shaft. The two ends of the two torsion springs are respectively fixedly connected to the inner walls of the support arm and the two ends of the rotating frame. This nailing machine has a smoothing capability, which can quickly smooth out wrinkles in the material at the nailing point, thereby ensuring processing speed and production quality.
