The invention discloses a piezoelectric ceramic driver pretensioning device. A threaded column is rotatably arranged on a base, and the threaded column and the piezoelectric ceramic driver are arranged in the same direction, and one end of the threaded column can lean against the end of the piezoelectric ceramic driver; The column is driven by a worm gear, and the thread of the worm wheel is set outside the threaded column; the worm and the thread of the worm wheel cooperate to form a worm gear mechanism. When the worm rotates, it drives the worm wheel to rotate. The axial position remains fixed, and the worm gear and the threaded column are screwed together. When it is necessary to tighten, turn the worm to make the threaded column close to the piezoelectric ceramic driver. One end of the piezoelectric ceramic driver is in contact with the threaded column, and the other end is in contact with the working mechanism. Contact, apply pressure through the threaded column, so that the piezoelectric ceramic driver and the working mechanism fit closely; the worm gear mechanism has self-locking characteristics, and the worm gear can only be driven by the worm gear, and the worm gear cannot reversely drive the worm gear to rotate, eliminating the possibility of loosening .

An equilateral multi-pass self-locking three-dimensional parking garage and its installation method. The garage includes two first shaft bodies and a second shaft body. The first shaft body includes a shaft body provided with threads, and the shaft body There are at least 2 parking platforms on the periphery, the second shaft body includes a threaded shaft body, and 1 parking platform is provided on the periphery of the shaft body; the parking platform consists of a ring body with internal threads and a ring body provided around the ring body Composed of at least 2 parking spaces, two first shafts and second shafts are adjacent to each other, a motor is installed on the parking platform, and a transmission screw is connected to the end of the motor, and the transmission screw and the shaft form a worm gear mechanism . With this structure, the vehicle on the parking platform can be moved conveniently and quickly through the up and down movement of the first shaft body and the second shaft body and the rotation of the parking platform, which effectively solves the problem of inconvenient movement of the vehicle in the existing garage. Moreover, on the basis of effectively saving land resources, as many parking spaces as possible can be set, which effectively meets the needs of people's daily parking.

The invention relates to a four-claw synchronous type mechanical unlocking automatic taking and putting device comprising a four-claw synchronous mechanical gripper and a cargo storage box. The four-claw synchronous mechanical gripper comprises an installing frame, an input motor, a T-shaped dual output speed reducer, a connecting rod transmission device, hook claws, fixed support legs and wedge-shaped anti-collision blocks. The fixed support legs are perpendicularly fixed to the lower portion of the installing frame. The hook claws and the wedge-shaped anti-collision blocks are held in the fixed support legs sequentially. The input motor on an installing frame bottom plate is connected with an input shaft of the T-shaped dual output speed reducer. Two output shafts of the T-shaped dual output speed reducer are connected with the first end of the connecting rod transmission device. The second end of the connecting rod transmission device is connected with the hook claws. The hook clawsachieve opening and closing motion relative to the fixed support legs through driving of the connecting rod transmission device. The cargo storage box comprises a box body, a box cover and fixing latch hooks. The fixing latch hooks are movably connected in second grooves in the four corners of the bottom of the box body, and hooking inclined plates are arranged in the positions, on the upper portions of the fixing latch hooks, in the second grooves.
