The device comprises a laser loading system, a control system, a heating system, a welding system, a clamping system and a three-dimensional mobile platform system; the laser loading system comprises a focusing lens, a lens support, a lens height adjustor, a reflector and a pulse laser; the control system comprises a computer, a laser controller, an air pressure controller, a heating controller and a three-dimensional mobile platform controller; the temperature system comprises a heating plate; the three-dimensional mobile platform system comprises a three-dimensional mobile platform and a right-angle base; the welding system comprises a restraint layer, an absorbing layer and a workpiece; and the clamping system comprises a workpiece, an air cylinder, a die driving device and upper and lower dies. According to the device and method, under the heating condition, by loading lasers, two layers of foil can be subject to impact welding and clamping at the same time, and the connecting strength of the foil is strengthened; and the die driving device in the device can drive the movable upper die to move left and right, the self-locking effect can be achieved, and the working efficiency is improved.

The invention discloses a rotary valve type membrane carburetor. The rotary valve type membrane carburetor is characterized in that a deepening staring device is included, the deepening staring device comprises a rocker arm, a rotating shaft and a rocker arm torsional spring, the rotating shaft is rotatably arranged in boss hole formed in one side of a fixing plate, the rotating shaft is fixedly connected with the rocker arm, the rotating shaft is returned through the rocker arm torsional spring after the rotating shaft rotates, the head portion of the rotating shaft is horizontally arranged below a swing frame, and the head portion of the rotating shaft is provided with a high spot and a low spot in the circumferential direction; when a motor is in a stage of igniting and starting and the swing frame is located at the lower limit position, after the rotating shaft rotates, the high spot of the head portion of the rotating shaft drives the swing frame, a plunger and an oil needle to move upwards simultaneously, wherein the plunger and the oil needle are connected with the swing frame. By means of the rotary valve type membrane carburetor, the purpose of deepening starting of the motor in a low-temperature environment is achieved.

The invention relates to a multifunctional worktable which comprises vertical columns and connecting plates movably arranged on the vertical columns. Big-end-up connecting holes are formed in the vertical columns, the vertical columns are conveniently and rapidly connected with the connecting plates in an inserted manner through the connecting holes, the connecting holes are obliquely formed in the vertical columns relative to plumb lines of the vertical columns, fasteners are arranged on the connecting plates and connected with the connecting holes in a matched and inserted manner, and worktable panels or storage plates or beams can be mounted on the connecting plates. The multifunctional worktable is convenient to assemble and disassemble, the distance between the worktable panel and thestorage plate and the storage plates or beams can be flexibly adjusted according to the requirements, so that use of users with different heights is met or objects with different specifications are stored, the beams and the storage plates can be welded or riveted, content is further increased, storage space of the worktable is greatly widened, the objects are systematically stored on the worktable, and convenient environments are provided for efficient working of the users.

The automobile air conditioner air door device includes an executor, a transmission mechanism, an air door baffle, and an air intake box, and the transmission mechanism includes an executor rotation arm, a driving rack and an air door rotation arm. The air door baffle is made to switch the position between the inner air intake and the outer air intake for realizing the inside circulation and the outer circulation of the air inside the automobile to ensure the ventilation and comfort effectively. The simple structure of the transmission mechanism and the small size of the air door device result in greatly reduced size of the whole air intake. In addition, the air door baffle has self-locking effect and the air door has excellent sealing performance.

The invention relates to a small animal tooth extraction tool, which belongs to a tool capable of solving relevant problems of small and middle animal tooth extraction. The small animal tooth extraction tool consists of a clamping system, a fixing system and a tooth extraction system, wherein the clamping system comprises a clamp jaw, a fixed clamp jaw block, a sliding clamp jaw block, a threaded connecting shaft, a worm wheel and worm gear, a worm gear shaft and a worm gear fixing frame; the clamping system forms an opening and closing state through the moving relative to a fixed clamp jaw; fixing assemblies are positioned at the two sides of the clamp jaw, and are fixedly connected with a main body; the height of the fixing position can be regulated through a retaining screw nut; the fixing assemblies can prevent a movable clamp jaw from moving so as to maintain the clamping state; the tool extraction system comprises a wedge-shaped slide block, a lead screw and a handle; the wedge-shaped slide block of the tooth extraction system is matched with an inclined groove formed in the sliding clamp jaw so that the clamping system upwards moves. Compared with the prior art, the small animal tooth extraction tool has the advantages that the operation is simple and fast; the work efficiency and the precision can be improved; the operation risk can be reduced.

The invention discloses a method for controlling water feeding of a pressure water valve by using a water current resistance change box. The method comprises a solar water tank; the water current resistance change box is mounted on the solar water tank; the upper part of the water current resistance change box is an overflow storage cavity; a valve hole is formed in a valve hole plate at the lower part of the overflow storage cavity; a floating valve cavity is below the valve hole plate; a valve cover is on a floating object in the floating valve cavity; a floating pipe is inserted in a hole between the floating object and the valve cover; a thin through hole is in the floating pipe; when no water is in an impedance box, the floating object falls down to enable the valve cover to leave from the valve hole; the thin through hole can enable an air clearance to become smooth in middle of the valve hole; at this time, the pressure in the water tank is lower; when water fed in the solar water tank is ascended into the water current resistance change box, the floating object upwards floats to close the valve hole; only the thin through hole is remained for passing through water; at this time, the pressure in the water tank is suddenly increased; and the suddenly increased pressure closes a self-locking pressure water valve. The method for controlling water feeding of the pressure water valve by using the water current resistance change box has no need to pull conduction wires into user homes, is liable to adjust and excellent in reliability, and is a good helper for water conversion of the solar water tank.
