The invention discloses a grass-cutting hob, a cutter welding tool of the grass-cutting hob and a manufacturing method of the grass-cutting hob, and belongs to the field of lawn machines and manufacturing processes of the lawn machines. By means of the grass-cutting hob, the cutter welding tool and the manufacturing method, the problem that existing grass-cutting hob manufacturing methods are high in cost or poor in quality is solved. The grass-cutting hob comprises cutters. Multiple insertion grooves are formed in each cutter. The corresponding insertion grooves are formed in each cutter with the circle center of the surface of the cutter as the central point according to an array with the angles between items being a. Positioning holes are formed in the cutters. The cutter welding tool of the grass-cutting hob comprises a base and multiple supporting plates perpendicularly arranged on the base at equal intervals. A cutter positioning block is arranged on one side of each supporting plate. The cutter positioning blocks correspond to the positioning holes. The manufacturing method of the grass-cutting hob mainly includes the step that the cutters are welded through the combination of the improvement mentioned above. The grass-cutting hob, the cutter welding tool and the manufacturing method mainly have the beneficial effect that on the premise of not increasing the production cost, the production efficiency and the quality of the grass-cutting hob are improved.

The invention relates to a lifting device for electronic equipment, which includes a mounting frame, a chain warehouse, a chain, a transmission gear and a driving motor; the chain includes a plurality of chain pieces and a plurality of bent chain pieces; adjacent chain pieces are connected by a bent chain piece, And the chain piece and the bent chain piece form a rotational connection through the rotating shaft; the driving motor is fixedly installed on the mounting frame, and the output shaft of the driving motor is connected to the transmission gear; the side of the chain corresponding to the transmission gear is arranged along its sliding direction. A driving body; the chain warehouse is fixedly installed on the mounting frame, and the chain warehouse is provided with a storage chamber for the chain to slide out or slide in when the driving body is moved by the transmission gear; one end of the chain is always located in the storage chamber. , the other end of the chain protrudes from the storage compartment and forms a connecting end; the end of the chain protruding from the storage compartment is vertically downward by gravity. The invention has an ingenious structural design, can achieve a longer lifting stroke in a limited space, and the lifting is stable and reliable, and can effectively reduce the problem of lifting and shaking.

The invention discloses a welding clamp for a multifunctional door shaft. The welding clamp comprises a base. Two transverse guiding grooves are formed in the surface of the base in parallel. A nut fixing groove is formed at the bottoms of the transverse guiding grooves. A hexagon nut is arranged in the nut fixing groove. The transverse guiding grooves are provided with a main shaft erecting plate and a connecting shaft erecting plate which are each provided with a longitudinal guiding groove. The longitudinal guiding grooves are internally provided with two butterfly bolts. The butterfly bolts penetrate the longitudinal guiding grooves and the transverse guiding grooves and are in threaded connection with the hexagon nut. Main shaft fixing plates are arranged on the two sides of the main shaft erecting plate respectively. First arc erecting grooves are formed in the middles of the tops of the main shaft fixing plates. A connecting shaft fixing plate is arranged on the side face of the connecting shaft erecting plate. A second arc erecting groove is formed in the top of the connecting shaft fixing plate. A concave clamping plate is arranged on the top of the connecting shaft fixing plate. The welding clamp is simple in structure, reasonable in design, convenient to use, high in adaptability, low in welding difficulty and high in yield.
