The robot polishing device that can replace the fixture according to the needs, through the mutual cooperation of the fixed plate, the fixed block, the sliding sleeve, the sliding rod, the handle, the block, the slot, the mounting plate and the mounting nail, so that the staff can adjust according to different needs. To replace the fixture body that fits the robot parts, it is no longer necessary to purchase various types of polishing machines, which saves the cost of robot polishing and improves the effect of use.

The invention relates to an expanded skin flap delayer, consisting of a bracket (1) and an expanded air bag (11). The expanded skin flap delayer is characterized in that the bracket (1) consists of a base (2), a telescopic rod (4) and a mechanical arm (6); the mechanical arm (6) is connected with the telescopic rod (4) by a spherical joint (5); the front end of the mechanical arm (6) is provided with a ring (7) which is provided with a small arm (8); one end (8B) of the small arm (8) is provided with a semicircular iron piece (9) which is connected with the small arm (8) by a screw (10); and the diameter of the expanded skin flap is matched with the semicircular diameter of the semicircular iron piece (9). The expanded skin flap delayer has the beneficial effects that a patient can perform preoperative delay of an expanded skin flap at home by self after being instructed by a doctor, and the defects that the traditional operation method has complex process and more complications, and is hard to carry out secondary correction after operation when delaying is carrying out on the expanded skin flap and the like.

This application relates to a method and device for predicting the effect of vitrification and recovery of human mature oocytes. The prediction method includes obtaining the basic information of the woman, the number of large and medium follicles in the application of follicle-stimulating drugs, test results of sex hormones, and infertility-related diseases. The results, as well as the man's semen test results; calculate the predicted probability P of no embryo transfer for the proposed egg cell cryopreservation operation 1 and the cumulative predicted probability of live birth P 2 ;according to P 1 and P 2 The numerical value predicts recovery effect. The forecasting device includes a memory, a processor, and a computer program stored in the memory and operable on the processor. The above-mentioned forecasting method is realized when the processor executes the computer program. This application estimates the recovery effect of the planned egg cell cryopreservation operation through the clinical history data and laboratory test results of the couple before egg retrieval, helps patients make reasonable decisions, minimizes the risk of unnecessary surgical operations and avoids Waste of time and medical resources.

The invention discloses a dustbin, which relates to the technical field of environmental protection; it comprises a box body with an upper opening, two groups of garbage bag supporting moving devices are arranged oppositely on the side of the opening of the box body, an upper cover is arranged on the opening of the box body, and an upper The cover is hinged on the upper cover seat, and the upper cover seat covers the garbage bag supporting mobile device; the supporting mobile device includes several synchronous wheels and a synchronous belt surrounding the synchronous wheel, and the synchronous belt and the outer wall of the box at the opening place the garbage bag Pressing along the edge, the outer wall of the box body is provided with a storage bag tube communicating with the inner cavity of the box body, and a side door is opened on the side of the box body opposite to the storage bag tube; the garbage bag supporting mobile device is provided with a motor that drives the synchronous wheel; the box body The inner cavity is provided with an adjusting groove for adjusting the height of the adjusting plate. The invention can solve the problems that when the garbage bag is full, the replacement personnel are easy to directly contact the garbage when replacing the garbage bag, which will cause adverse effects on the body and the problem that the operation of replacing the garbage bag is troublesome.

The invention discloses a spraying device for the processing of auto parts, which comprises a fixed shell, the four corners of the bottom of the fixed shell are fixedly connected with support plates, the left and right sides of the bottom of the fixed shell are fixedly connected with adjustment devices, and the left and right sides of the inner wall of the fixed shell are fixedly connected with support plates. Movable devices are arranged on both sides, a cylinder is fixedly connected to the midpoint of the bottom of the inner wall of the fixed shell, and a fixed plate is fixedly connected to the top of the cylinder. The present invention achieves the effect of automatic spraying through the mutual cooperation of rotating motor, rotating shaft, reel, fixed rope, sliding rod, sliding block, buffer spring, cylinder, fixing plate, connecting plate and stabilizing plate, and solves the common problem Most of the spraying devices used for auto parts processing are manual spraying, which reduces the spraying time, improves the quality of the product after spraying, avoids the impact of long-term spraying on the health of employees, improves work efficiency, and reduces manpower consumption. It brings great convenience to users.

The invention discloses a method for the anti-seepage construction between a hidden frame glass window and a building structure, which comprises the following steps: firstly, according to the separation distance and the shape of a structural surface at a joint seam of the outer side of a window frame and the building structure, cutting a waterproof sheet material made of ethylene propylene diene rubber; adhering the waterproof sheet material to the joint seam by using a waterproof paste, and then compacting and fixing the waterproof sheet material and the joint seam of the building structure and the window frame by using an aluminum strip; fully packing the gaps between the periphery of the window frame and the adjacent building structure by using a foaming agent; and mounting a piece of glass, then packing the foaming agent in the joint seam of an aluminum sleeve frame and an adjacent structure, closing up the joint seam on the outer side of the foaming agent by using a mortar, and finally sealing joint seam by using a weatherproof sealant. According to the method, the ethylene propylene diene rubber sheet material, the foaming agent and the weatherproof sealant form a three-path waterproof thin part node, so common quality problems of the seepage on the periphery of the window frame are effectively controlled; besides, the material can be recycled for reuse, and simultaneously the maintenance caused by the seepage is reduced during engineering use.
