The utility model relates to the technical field of silicon core processing, in particular to a perforating machine and a feeding and discharging device thereof. A feeding and discharging device of a perforating machine comprises at least two placing assemblies used for placing workpieces, at least one placing assembly used for feeding and at least one placing assembly used for discharging, and the placing assemblies are arranged in a straight line; the material taking assembly comprises a feeding finger and a discharging finger, the feeding finger and the discharging finger are arranged at an angle, and a switching driving part drives the feeding finger and the discharging finger to switch positions; and the driving module extends above the placing assembly, and the driving module drives the material taking assembly to move in a multi-dimensional mode. The technical problems that in the prior art, the falling risk exists in the feeding and discharging process of workpieces, and the workpieces are prone to being damaged are solved.

This invention belongs to the field of manual razor technology, and specifically relates to a double-blade head structure for manual razors. It aims to solve the problems of existing manual razors requiring the use of separate lubricating materials applied by hand, which is unhygienic and prone to causing finger cuts, and the easily lost separate blade protector. This invention includes a main frame, blades, and a handle. Two collapsible clamps are located in the middle of the main frame. The handle contains a cavity and a piston head. The forward push of the pressure block synchronously drives the piston head to extrude shaving gel and the linkage mechanism to move upwards, opening the cover. The backward pull, via the linkage mechanism, trigger rod, connecting rod, and connecting frame, synchronously drives the clamps to close, smoothing the gel and resetting the piston head. A one-way valve prevents the extruded gel from flowing back. This invention integrates the functions of extrusion lubrication, clamp smoothing, and cover opening / closing into a single operating stroke within a single push-pull cycle, eliminating the need for finger contact with lubricating materials, making it convenient and safe to use.

The tool comprises a first scissor arm and a second scissor arm, a scissor part of the first scissor arm is provided with a detachably-connected scissor seat assembly, a scissor platform part of the second scissor arm is provided with a detachably-connected scissor platform, a scissor seat of the scissor seat assembly comprises a base and a vertical plate, and at least two inserting grooves are formed in the top of the vertical plate; the lower end of the front wall of the inserting groove extends forwards to form a clamping groove, an inserting hole corresponding to the inserting groove is formed in the top face of the scissor part, the sliding lock pin penetrates through the inserting hole to be arranged in the inserting groove, a clamping hook matched with the clamping groove is arranged at the front end of the sliding lock pin, the inserting hole moves the sliding lock pin, clamping or separation of the clamping hook and the clamping groove is achieved, and locking or unlocking operation of the scissor holder is completed. The operation area is arranged on the upper portion away from the blade, the sliding lock pin is arranged, and the fixing structure is firm and stable; when the tool apron assembly is disassembled, a hand does not need to directly contact a cutting edge area, the finger cutting risk is avoided, and the safety and efficiency of replacement operation are improved.

This utility model relates to the field of electric pruning shears, and discloses an electric pruning shear to prevent accidental finger cuts. It includes scissors, an infrared sensor on one side of the scissors, a temperature sensor on the surface of the scissors near the infrared sensor, a start button inside the scissors, a locking hole at the bottom of the start button, a pressing groove on one side of the locking pin, a pressing plate slidably connected inside the pressing groove, an adjustment mechanism for adjusting the pressing plate on one side of the pressing plate, and a sliding groove on one side of the pressing plate, containing a constraint mechanism for restraining the pressing plate. This utility model, through the sensor, can protect the left hand to prevent finger cuts. Because the sensor is connected to a controller inside the scissors, when the controller receives information, it sends a command to the motor drive module to stop the motor, thus preventing the scissors from cutting the finger.
