The utility model provides a lithium battery substrate positioning structure, which relates to the technical field of battery substrate positioning and comprises an adjustable positioning frame. The adjustable positioning frame body is of a square frame-shaped structure, and the lithium battery substrate is positioned in the adjustable positioning frame body; four adjusting screw rods are mounted in the adjustable positioning frame body; two positioning movable clamping plates are connected into the top of the adjustable positioning frame body, and four fastening nuts are connected to the top of the adjustable positioning frame body. According to the utility model, the connection part of the four L-shaped movable frame strips can be adjusted in a sliding manner according to the length and width specifications of the lithium battery substrate, so that the four L-shaped movable frame strips can be contacted with the edge of the lithium battery substrate at the same time to play a role in limiting the lithium battery substrate, and the length and width of the lithium battery substrate can be adjusted according to different thicknesses of the lithium battery substrate. And the positioning movable clamping plate connected with the adjustable positioning frame body is adjusted to move up and down, so that the bottom side of the positioning movable clamping plate can be in contact with the top side of the edge of the lithium battery substrate, and the effect of clamping and fixing the lithium battery substrate is achieved.

The present invention relates to a projectile recovery device, specifically, a device for buffering and collecting projectiles shot horizontally by a catapult device within a short distance. Compared with the prior art, the present invention utilizes the deep cavity shape unique to common tires and the high elasticity, large damping and impact resistance of rubber, cord and steel wire composite materials, which can effectively implement frontal buffering and rebound blocking for incoming high-speed projectiles. The narrow deep-hole buffer recovery space is formed by combining serially connected tires, which can effectively limit the rebound path and rebound stroke of the projectile. In addition, the filling of buffer materials in the tire cavity and the net bag in the optimized solution can further improve the buffering efficiency, safety and service life of the device. The whole solution has a compact structure, a short recovery stroke, high recovery efficiency, and controllable rebound of the projectile, which is suitable for use in a small space.

The utility model provides a high-safety automatic spectrum sample grinding machine, and relates to the technical field of sample grinding machines. The bottom connecting base is fixedly connected with a machining platform of a spectrum sample grinding machine, and two movable lifting blocks are symmetrically installed on the top of the bottom connecting base. The tops of the movable lifting blocks are connected with a top connecting base, and a screw A is installed at the bottom of the top connecting base and connected with the two movable lifting blocks. Four guide sliding rails are installed on the top of the top connecting base, movable clamping strips are connected to the tops of the guide sliding rails, and the two movable clamping strips are symmetrically located on the top of the top connecting base.
