The present invention is to provide a mechanism for rapidly installing and detaching a hard disk, comprising a U-shaped handle pivotally mounted at both sides of the hard disk and having a latch in a forward side, and a frame for receiving the hard disk having an elastic member in a forward end and a projection on a side of the elastic member for engaging with the latch while the handle being pivoted down into a gap between the hard disk and the frame, enabling the sides of the hard disk to urge against the frame and the handle and be firmly installed in the frame. While detaching the hard disk from the frame, it only needs to push the projection outward until being disengaged from the latch and then pull the handle upward to remove the hard disk from the frame.

A bracket is used for an electronic device into a frame. The frame includes two opposite wall surfaces and at least one pair of guiding rails disposed on the two wall surfaces. The bracket includes a main connection portion, two main elastic arms, and main engaging posts. The main elastic arms respectively extend from two ends of the main connection portion. The two main elastic arms extend towards the same direction with a clamping space defined between the two main elastic arms for accommodating the electronic device. The main engaging posts are respectively disposed on sides of the two main elastic arms facing each other, so that the main engaging posts extend towards the clamping space for engaging lateral surfaces of the electronic device. The two main elastic arms respectively slide along the two guiding rails, so as to fix the electronic device into the frame.

The invention provides a quick release structure which comprises a shell, a button and a sliding piece, the shell comprises a sunken part, an opening and a plurality of fixing grooves, the sunken part is located below the rear side of the shell, the opening is communicated with the sunken part, the fixing grooves are formed in the front side of the shell and are adjacent to the opening, the button is arranged in the opening, and the sliding piece is arranged in the button. The button comprises a body part and an extension part, the body part is connected to the extension part, the body part comprises a contact surface and a suspension surface, the suspension surface is adjacent to the contact surface, the suspension surface is exposed by the sunken part, the extension part comprises a plurality of sliding groove structures, the sliding groove structures correspond to and are clamped in the fixing grooves, and the sliding part abuts against the button. When no force is applied to the button, the button is located at the first position, the sliding piece is located at the first fixed point, after the force is applied to the button, the button acts relative to the shell, moves from the first position to the second position and drives the sliding piece to move from the first fixed point to the second fixed point, and the screen can be rapidly assembled on the base foot stand.

A blind cord guide seat includes a connection seat fixed under a blind rail and a cord restriction seat connected under the connection seat. The cord restriction seat includes a fixing section and a latch section. An outer face of each of the fixing section and the latch section is formed with a belt guide channel. The top end of the fixing section is formed with threaded holes for connecting with the connection seat by screws. When assembled with a cord winding device, an external force is applied to the latch section to outward bias the latch section to provide an opening for placing the cord winding device through the opening into the cord restriction seat. An iron-made hook bracket and a latch body are securely disposed at the upper end of the latch section for securely latching the latch section with the connection seat.

The invention discloses a connecting structure for a safety pin and a chuck seat of a rear tire inflating device. The safety pin is detachably connected with the chuck seat, the chuck seat is provided with a frame body, the frame body is connected with a swinging element in a rotating manner, one side, provided with a rotary connection point, of the swinging element is connected with the safety pin in a clamping manner and also connected with a pivot through an elastic element, and the other side of the swinging element comes into contact with or is connected with the chuck seat. Compared with the prior art, the connecting structure has the advantages that the combined action of the chuck seat as well as the swinging element and elastic element which are arranged on the chuck seat are effectively utilized, so that the chuck seat can be effectively positioned at a high position, the chuck seat also can be positioned on the safety pin when the air cylinder is out of work or mis-operated manually, the falling of the chuck seat can be effectively prevented, and the ground personnel and parts can be prevented from being damaged.

The invention discloses a connecting structure of a plug pin and a chuck seat of a tire rear inflation device. The plug pin is connected with the chuck seat detachably; a pressing-downwards element is clamped on the plug pin; an elastic element is arranged between the press-downwards element and the chuck seat. Compared with the prior art, the connecting structure effectively utilizes the chuck seat self as well as the combined action of the press-downwards element and the elastic element which are mounted on the chuck seat, and thus, the chuck seat is effectively positioned at a high position and the chuck seat also can be positioned on the plug pin under the condition that a cylinder is in failure or is artificially and falsely operated, so that the chuck seat is effectively prevented from falling off and that ground service staff and parts are not damaged is ensured.

The invention provides a concrete bridge supporting column construction operation method. The concrete bridge supporting column construction operation method adopts the following equipment for construction, the equipment comprises a lower mold, an upper mold, a connecting piece and a demolding device, the lower end of the lower mold is installed on the existing ground, the upper mold is arranged above the lower mold, the connecting piece is mounted between the upper end of the lower mold and the lower end of the upper mold, and the demolding device is arranged at the left side of the upper mold. Through mutual cooperation of a first motor, a rotating shaft, a rotating rod and a rolling wheel, the rolling wheel can synchronously rotate on the edge of a disc, the rolling wheel, an L-shaped column, smf a hinge rod and a lug base are matched with one another, so the lug base pulls the arc-shaped block to disassemble the upper mold, the function of rapidly disassembling the upper mold can be achieved without manual work, and then the efficiency of construction operation of the concrete bridge supporting rod and the safety degree of the construction process can be improved.
