The temperature threshold actuator provided by the present invention includes a first chamber and a second chamber, the first chamber is used for the actuator to pass through, the second chamber is provided with a shape memory alloy spring, one end of the spring is fixed, and the spring is movable. The end and the executed part are linked and connected through a linkage rod. In this solution, when the temperature of the monitored environment rises, the temperature of the actuator will rise rapidly. Once the temperature of the shape memory alloy spring reaches the transition temperature, it will extend rapidly. At this time, the movable end of the spring drives the executed part to move through linkage. Extending into the second cavity causes the actuated part to have a larger bend, so that the loss caused by the bend exceeds a threshold value, and realizes the timely perception of the temperature change of the monitored environment. The device has a simple structure and high reliability, and can work stably in harsh environments such as humidity and dust.

The invention relates to a high-precision guide rail correction device and belongs to the technical field of high-precision correction devices. The high-precision guide rail correction device comprises a base, wherein a correcting groove for accommodating and being propped against a guide rail is formed in the base in the length direction of the base in a penetrating manner; a correcting block isvertically arranged on the inner wall of one side of the correcting groove in a sliding manner; the two sides of the correcting block are propped against the side walls of the guide rail and the sidewalls of the correcting groove; the side wall, far away from one side of the correcting block, of the correcting groove is propped against the other side wall of the guide rail; an adjusting bolt is jointly connected between the correcting block and the base, vertically penetrates through the base, is in threaded connection with the base and drives the correcting block to vertically move up an down; and when the correcting block moves upwards, the correcting block moves towards one side of the guide rail. According to the high-precision guide rail correction device, through matching of the correcting block and the base, and under driving of the adjusting bolt, the correcting block simultaneously moves in the vertical and horizontal directions to replace the traditional manner that the guide rail is manually broken off, and the problem about correcting precision caused by unbalanced force application is solved.

The invention provides a flexible electrochromic device and a manufacturing method thereof. The flexible electrochromic device includes a conductive layer, a color-changing layer and a conductive gel layer. The conductive layer has no substrate and can be freely bent, and the color-changing layer is arranged above the conductive layer. , the conductive gel layer is arranged above the color-changing layer. The present invention provides a flexible electrochromic device and a manufacturing method thereof. On the one hand, by using a grid structure without a substrate as a conductive layer, the thickness of the flexible electrochromic device is lower than that of the existing electrochromic device, and the improvement is improved. The conductivity and overall transmittance of the electrochromic device are improved, and the manufacturing cost is reduced; on the other hand, the present invention adopts a grid structure without a substrate as the conductive layer, and cooperates with the conductive gel layer, which can achieve far higher than the existing The degree of bending of the electrochromic device. In addition, the conductive gel layer itself has stickiness and can be adhered to the surface of most objects, thus realizing the applicability of the electrochromic device.

The invention relates to the technical field of finger exercise equipment, in particular to a finger strength exerciser for fracture rehabilitation and an exercise method. Aiming to solve the technical problem that the flexibility is inconvenient to recover through slow exercise after a finger takes off gypsum, the invention provides a finger strength exerciser for fracture rehabilitation. The exerciser comprises a palm block, a semi-ring groove is formed in the surface of the palm block and close to the two-thirds position of the top; the two sides of the inner wall of the semi-ring groove are connected through arc-shaped rods, rotating sleeves movably sleeve the arc-shaped rods, palm center bent plates are fixedly connected to one sides of the surfaces of the rotating sleeves, and one sides of the inner walls of the palm center bent plates are movably connected with the palm block. According to the invention, the five fingers are placed on the five finger exercisers respectively; when the fingers are gradually and slowly bent, the finger joints at the tail ends are firstly bent, the elastic pieces can be slowly bent; if the fingers exert insufficient force, the fingers can be lifted up, the fingers can be moved in the lifting process, and therefore, the fingers can be assisted in recovering flexibility.

The invention relates to a high-precision guide rail correction device, which belongs to the technical field of high-precision correction devices. It includes a base, and a correction groove for accommodating and touching the guide rail is formed through the base along its length direction. The inner wall of one side of the correction groove is vertically slid. There is a correction block, the two sides of the correction block are respectively in conflict with the side wall of the guide rail and the side wall of the correction groove, and the side wall of the correction groove away from the correction block is in conflict with the other side wall of the guide rail; the correction block and the base are jointly connected with An adjustment bolt, the adjustment bolt vertically penetrates the base and is threadedly connected with the base, the adjustment bolt drives the correction block to move vertically up and down, and when the correction block moves upward, the correction block moves toward the side of the guide rail. Through the cooperation between the correction block and the base, the invention realizes the simultaneous movement of the correction block in the vertical direction and the horizontal direction under the drive of the adjustment bolt, replaces the traditional way of breaking the guide rail by hand, and solves the problem of correction accuracy caused by unbalanced force .
