The invention discloses a spring band installation fixture which comprises an annular bracket, wherein multiple cylinders are evenly arranged on the outer wall of the annular bracket along the circumferential direction of the bracket, each cylinder comprises a piston rod which stretches out and draws back along the radial direction of the bracket and extends to the inner side of the bracket, a claw piece which is used for hooking the inner circle of the spring band and applying radial outward tension is fixed on the tail end of the piston rod of each cylinder, which is arranged at the inner side of the bracket, and the cylinder body of each cylinder is communicated with an air source through an air channel connecting pipe. The claw pieces can be driven to move outwards along the radial direction of the bracket by the piston rods and the spring band is driven to expand outwards by the claw pieces, thus the expansion of the spring band can be easily realized, the operation is simple and the assembly efficiency is high.

The invention discloses an unmanned aerial vehicle with unfoldable or foldable fan blades. The unmanned aerial vehicle includes a main vehicle body, which is internally equipped with a transmission cavity 1, a storage cavity is formed under the transmission cavity 1, a lower side wall of the storage cavity is communicated with the outside of the main vehicle body, a camera is arranged on the lowerside of the storage cavity, and a transmission device 1 for driving the camera to rotate by 360 degrees is arranged in the storage cavity. The unmanned aerial vehicle with unfoldable or foldable fanblades is simple and convenient to operate, and low in manufacturing cost, can realize unfolding or folding of the fan blades through spiral cooperation of a screw rod 4 and a nut 3, the overall sizeof the unmanned aerial vehicle is reduced, space is saved, and also the camera can be stored in the storage cavity through spiral cooperation of a disc 1, a screw rod 1 and a screw rod 2 so as to be prevented from being bumped.

The invention discloses a trial mold of an expandable intervertebral fusion device, which belongs to the field of intervertebral surgical instruments, and comprises a trial mold body and a fixing tube. It is set and screwed to the adjustment table. The test mold body includes two test modules. The test modules are slidably connected to the adjustment table. The adjacent side of the two test modules is provided with a guide surface that is in contact with the adjustment rod. The two guide surfaces are symmetrical. Set and tilt from one end close to the adjustment table to one end far away from the adjustment table. The application has the effect of improving the fitting degree of the size of the cage and the space between the two vertebral bodies.

The invention provides an intelligent umbrella. The intelligent umbrella comprises an umbrella body composed of an umbrella rod, an umbrella framework, an umbrella cover and a handle, wherein the umbrella rod is internally provided with an inertia measurement device, a main controller and a hoisting device; the inertia measurement device is used for acquiring inertia information of the umbrella body in a current movement state and carrying out conversion processing on the inertia information to obtain a corresponding electric signal; the electric signal comprises a first electric signal or a second electric signal; the main controller is used for controlling the hoisting of the hoisting device according to the first electric signal and controlling the descending of the hoisting device according to the second electric signal; the hoisting device is used for controlling the hoisting of the hoisting device according to the first electric signal and is used for driving the umbrella framework to open the umbrella cover, and controlling to descend according to the second electric signal so as to drive the umbrella framework to close the umbrella cover; and automatic control of hoisting the umbrella and opening the umbrella, and descending the umbrella and closing the umbrella can be realized, and manpower is not needed, so that the utilization efficiency is improved, the experience degree of a user is relatively good and the practicability is relatively excellent.

The invention discloses a mink tube dividing device for mink fur production, relates to the technical field of garment production, and solves the problems of troublesome mink cutting operation, low production efficiency and poor safety in the prior art, including a main body; There is a group of motors fixedly connected to the rear of the top of the main body; a group of flywheels is axially connected to the top of the main body; a group of conveying mechanisms are arranged on the front face of the main body; a group of intermediate transmission shafts are axially connected inside the main body; the conveying mechanism is a conveyor belt structure, and the conveying mechanism The outer front end surface of the transmission belt is fixedly connected with multiple sets of mink fur barrel fixing mechanisms; the front end surface of the main body is slidably connected with a group of cutting mechanisms. The device has a simple structure and is easy to operate. It can quickly cut the mink fur tube and has high cutting efficiency. Only one person is required to realize the operation. At the same time, the operator does not use a knife when cutting, which has higher safety.

The invention discloses a preparation process of cold-clearing and heat-clearing granules with heat-clearing and heat-clearing functions. The specific preparation process is as follows: extract volatile oil from nepeta ears, peppermint and perilla leaves, and collect the distilled aqueous solution in another device; extract the medicinal residues Add water to boil twice with Fangfeng, Bupleurum, Pueraria lobata, Platycodon grandiflorum, Bitter almond, Angelica dahurica, Kudiding, and reed rhizome, then filter, and combine the filtrate with the aqueous solution in the first step to concentrate into a clear paste; prepare the clear Appropriate amount of sucrose, dextrin and ethanol are added into the paste to make granules, which are then packaged and sealed. The present invention carries out bagging and encapsulation through the feeding and filling bagging device, and lifts the prepared particles from the bottom to the filling and sealing bag mechanism by lifting the feeding mechanism, and then seals the bag. The setting of the lifting and feeding mechanism can realize low-cost After feeding, the material is automatically transported to a high place for filling, which realizes the automatic lifting and feeding process and improves the processing efficiency.
