The invention relates to a device for stacking and storing micropore plates and a micropore plate transferring device and method. The device for storing the micropore plates comprises a plate storagerack, a lifting mechanism and plate storage parts, wherein the plate storage rack comprises a plate storage channel for stacking the micropore plates. The plate storage parts are located on the lowerside of the plate storage rack, and the lifting mechanism is arranged below the plate storage channel. When the lifting mechanism ascends or descends to the preset position, all the plate storage parts retreat out of or are inserted in the plate storage channel, and through collaborative work of the lifting mechanism and the plate storage parts, the functions of micropore plate releasing and micropore plate storage are achieved. The micropore plate transferring device comprises a movable tray, a first device, a second device and a plurality of transit plate transferring devices located betweenthe first device and the second device, wherein the first device and the second device are used for stacking and storing the micropore plates. The movable tray reciprocates between the first work position and the second work position, micropore plates released by the first device are received, pass through the transit plate transferring devices and are placed at the second work position, and accordingly the function of moving of the micropore plates in a transferring manner is achieved.

The present application relates to a reciprocating saw, which has a working stroke state and an idle stroke state, including: a casing; a motor, located in the casing; a transmission mechanism, which is driven by the motor to drive the saw blade to reciprocate; a detected object is arranged on the transmission mechanism , moves with the movement of the transmission mechanism, and can move to the first position, and when the detected object moves to the first position, the reciprocating saw is in a working stroke state or an idle stroke state; the first detector is used to detect the detected object. The object is arranged opposite to the first position; the control circuit board is electrically connected to the first detector and the motor, and when the first detector detects the object to be detected, the rotation speed of the motor is adjusted. The present application can effectively control the rotational speed of the motor according to the travel requirements, thereby solving various application problems.

The invention relates to a cable testing device with a standardized circuit design. The cable testing device comprises a device shell, an input device, a transmission device, a triggering device and an alarm device, and the invention discloses a testing method of the cable testing device with the standardized circuit design. The testing method comprises the following steps: step 1, mounting; step2, driving; step 3, detecting. According to the cable testing device and the testing method for the standardized design of the circuit, the testing device moves on the cable, and each trigger switch synchronously swings back and forth when moving along the cable, so that each trigger switch forms a wavy advancing track on the cable; when the trigger switch passes through the damaged part of the cable, the compression spring drives the corresponding sliding insertion rod and the limiting side block to move downwards, and the metal moving contact and the metal static contact are in contact, so that the buzzer is electrified to buzz, and the damage of the surface of the cable is detected.

The invention provides a gravity balancing device on a Z-direction working platform, and an elastic device fixed on a base and can provide an upward force for a slide carriage. The embodiment of the invention also provides a cutting machine which comprises a Z-direction working platform, wherein the Z-direction working platform comprises a base, a screw which can be rotatably arranged on the base, and a slide carriage which is arranged on the screw and can be driven by the screw to move relative to the base; and the Z-direction working platform is provided with a gravity balancing device. When a moving part of the Z-direction working platform provided with the gravity balancing device reciprocates, the elastic device fixed on the base supplies an upward force to balance the downward gravity of the moving load, thus the problem that the screw cannot be locked automatically is solved, and the adverse effect of the load gravity is eliminated simultaneously. As for the cutting machine provided by the invention, the Z-direction working platform thereof is provided with the gravity balancing device, thus the problem that the screw cannot be locked automatically is solved, and the adverse effect of load gravity is eliminated simultaneously. The cutting machine runs with lower noise, is particularly suitable for high-speed and high-precision cutting, and greatly reduces the manufacturing cost.
