The utility model discloses a punching device for a left upper mounting bracket of an automobile air conditioner box body, which comprises a working table, and the top of the working table is fixedly connected with a bracket. In the actual use process, the support is fixed to the workbench, the electric hydraulic rod at the top of the support is started to push the connecting plate to move downwards, the punching head and the pressing plate are driven to move downwards together, and when the punching head makes contact with a workpiece, the pressing plate is pressed upwards through counter force, the sliding rod moves upwards to stretch the first spring, waste is pushed into a discharging hole during punching, and punching is completed. When the punching head moves upwards, if waste is attached to the punching head, the clamping plate is tightly attached to the punching head under the action of the second spring, the waste is clamped by the clamping plate, when punching is conducted next time, the waste falls off along with new waste, and before the punching head is separated from a workpiece, the pressing plate tightly presses the workpiece to prevent the workpiece from moving upwards, so that the punching head is prevented from being damaged. The device solves the problems that according to an existing punching device, waste is inconvenient to clean, and workpieces are prone to displacement.

The utility model discloses a sewage treatment's dosing device concretely relates to sewage treatment technical field, including soaking assembly, and the top of soaking assembly is provided with a plurality of limiting components, and the inner chamber of soaking assembly is provided with movable assembly, and soaking assembly includes soaking pool, and the both sides top of soaking pool inner wall all are provided with the sliding slot, and the top fixedly connected with the water inlet pipe of one side of soaking pool outer surface, and the water outlet is provided with the plug in the water outlet, and the bottom fixedly connected with the water diversion board in soaking pool. Solveed in the prior art, when carrying out sewage treatment, because need to put in medicine to mix sewage, the medicine of sewage can only purify the sewage in a certain area, therefore need to put the medicine for many times, and need to move the feeding device for many times, lead to the problem of more troublesome removal.

The utility model discloses a hand-held seeder, and relates to the technical field of seeders, and the hand-held seeder is characterized in that one side of a seeder body far away from a pull rod is provided with a chute, a sliding rod is slidably connected in the chute through a spring I, and one end of the sliding rod penetrating out of the chute and one side far away from the pull rod are provided with a fixing groove; and moving blocks are detachably connected into the fixing grooves, rotating shafts are rotatably connected to the moving blocks, telescopic rods are slidably connected to the two ends of each rotating shaft, and tires are rotatably connected to the ends, away from each other, of the telescopic rods through bearings. The distance between the seeding machine body and the ground can be adjusted by fixedly connecting the moving block to the through hole at the proper height in the sliding groove, the distance between the two tires can be adjusted by adjusting the distance of the telescopic rod penetrating out of the through groove, and the seeding machine body can be supported and moved through the two tires; therefore, the force applied by moving the seeder body is reduced, and the labor intensity is reduced.

This utility model provides a connector protective shell assembly and a connector, belonging to the field of connection devices. The connector protective shell assembly includes a fixing plate, with two pressure-bearing limiting members fixed to its lateral ends. The two pressure-bearing limiting members are arranged laterally at intervals, forming a cavity for accommodating a terminal module. The longitudinal ends of the pressure-bearing limiting members are respectively used for surface support engagement with a printed circuit board and for support engagement with the inner side of the fixing plate. The pressure-bearing limiting members meet the requirement that their longitudinal pressure-bearing capacity is not less than the working pressure of the pressing fixture, so that when the terminal module is assembled in place, the pressure-bearing limiting members can bear the pressure of the pressing fixture and limit the pressing distance of the pressing fixture. The connector includes the aforementioned connector protective shell assembly. This utility model provides pressure-bearing limiting members on both lateral sides of each terminal module for support and protection, thereby preventing the terminal module from being subjected to excessive pressure after being pressed in place.
