The invention discloses a steel plate drilling device convenient to use. The device comprises a base, the top of the base is provided with a support base and a first motor in sequence from left to right, an output shaft of the first motor is provided with a belt, the belt penetrates through the base and extends into the base, the top of the support base is provided with a motor case, a water tank, a water outlet pipe and a water pump in sequence from left to right, a second motor is fixed into the motor case, and an output shaft of the second motor sequentially penetrates through the bottom of the motor case and the top of the support base and extends into the support base. According to the steel plate drilling device convenient to use, through arrangement of a rotating rod and an automatic extending-and-contracting rod, when the rotating rod rotates, a rotating drum is driven to move downwards in a second sleeve through a thread on the surface of the rotating rod, thus the drilling device can stably press a steel plate and be stressed uniformly, the service life of the drilling device is prolonged, and work efficiency of people is improved.

The invention discloses a pressing device and optical detection equipment, and belongs to the technical field of optical detection. The optical detection equipment comprises the pressing device, the pressing device comprises a cover plate, a plurality of jacking mechanisms, a first supporting structure and a pressing mechanism, and the cover plate is used for optical detection; the jacking mechanism is used for driving the cover plate to ascend and descend. The pressing mechanism comprises a driving part and a pressure bearing part, the driving part is connected to the output end of the jacking mechanism, the pressure bearing part is connected to the cover plate, and the driving part is used for driving the pressure bearing part to press downwards so as to drive the cover plate to press downwards. The pressing device can be suitable for flattening PCBs warped or raised in different degrees, and the detection precision of the optical detection equipment is improved.

The invention belongs to the technical field of dicing machines and provides a self-adaptive press-down device. The device comprises a rack, a first roller, a second roller, a third roller, two firstconnecting rods, a fourth roller, two second connecting rods and a first conveying belt, wherein the first roller and the second roller are both rotationally arranged on the rack in the transverse direction; the two sides of the rack are provided with first strip-like mounting holes respectively in the longitudinal direction, and the two ends of the third roller are arranged in the two first strip-like mounting holes respectively in a sliding mode; one end of each first connecting rod is rotationally connected with one end of the first roller; the other end of each first connecting rod is rotationally connected with one end of the fourth roller; one end of each second connecting rod is rotationally connected with one end of the third roller, and the other end of each second connecting rodis rotationally connected with the other end of the fourth roller; and the first conveying belt is wound around the first roller, the second roller, the third roller and the fourth roller. Through thetechnical scheme, the problem that in the prior art, a press-down device cannot be adjusted automatically according to the size of a material is solved.

The invention discloses a surface charging device for shared electric vehicle. The structure comprises a housing protection device, circuit control box, Charger box, charge gun head, the invention hasthe advantages that: sharing the weight of an electric car and the structure of four wheels, the invention avoids other vehicles needing to be charged from occupying the parking space of the shared electric vehicle for charging, At that same time, by separate the charging gun head from the trig device, the charging port of the shared electric vehicle is at the position of the charging gun head aft the electric vehicle is parked, the problem that the charging wire is too long or too short is saved, and the charging wire can be quickly and effectively sorted through the design of the winding column; By embedding the whole equipment under the parking area for the use of the shared electric vehicle parking space, the use function of the parking area can be enhanced, and at the same time, thewater-proof and leakage-proof work can be done well, so that the shared electric vehicle can be charged conveniently, and the charging piles do not need to be searched everywhere, and are convenient to use.

The invention discloses a contact-finger installing tool for a high-voltage isolating switch, wherein a transverse passage is arranged in the lower part of an installing part, a connecting rod is arranged in the transverse passage, a hook is arranged at the front end of the connecting rod, the hook extends out of the front end of the installing part, the rear end of the connecting rod is connected with a hand-pressing handle through an inclined rod, a shaft-pin passage which is vertical to the transverse passage is arranged at the front end of the installing part, a pin outlet is arranged at the lower part at the front end of the installing part, the pin outlet is communicated with the shaft-pin passage, the pin outlet is communicated with the transverse passage, an open slot which can be used for containing the end part of a contact-finger stretched spring is arranged at the front end at the lower part of the installing part, the upper end of the installing part is in shaft connection with a pressure plate, a second reset spring is arranged between the pressure plate and the installing part, a column body for downwards pushing and pressing a shaft pin is arranged at the front end of the pressure plate, and a pushing and pressing mechanism is arranged between the pressure plate and the hand-pressing handle. The invention has the advantages that when the installing tool is operated, the hand-pressing handle only needs to be pressed to pull out the contact-finger stretched spring, meanwhile, the shaft pin is nailed into the end hole of the contact-finger stretched spring, and the installing tool is quite convenient to operate.
