Disassembly and assembly tool for narrow and small space and disassembly and assembly method for fastener

Abstract

The invention provides a disassembly and assembly tool for a narrow space and a disassembly and assembly method for a fastener and belongs to the field of disassembly and assembly tools of connectors.The problem of low efficiency of screwing the fastener in the narrow space in the prior art is solved. The disassembly and assembly tool for the narrow space comprises the fastener and a disassemblyand assembly tool body, the fastener comprises a threaded rod of which the top is provided with a disassembly and assembly groove, and external locking grooves are formed in the groove wall of the disassembly and assembly groove; the disassembly and assembly tool body comprises a rod sleeve of which the sleeve wall of the bottom is provided with external locking holes, external locking columns located in the external locking holes, a push rod which penetrates through a rod hole, a grip of which the front end is sleeved with the top of the rod sleeve through a sleeve hole and an adjustment sleeve which sleeves the grip; the rod hole is formed in the rod sleeve, internal locking grooves are formed in the rod wall of the push rod, and an adjustment groove is formed in the rod wall of the pushrod; a fixing hole is formed in the sleeve wall of the rod sleeve, an adjustment hole is formed in the grip, and an adjustment rod penetrates through the adjustment hole; a rod groove is formed in the grip, and two reset springs which sleeve the adjustment rod are arranged in the rod groove. The disassembly and assembly tool is matched with the fastener so that operation can be conducted conveniently in the narrow space.

Description

technical field [0001] The invention belongs to the technical field of disassembly and assembly tools for connectors, and relates to a disassembly and assembly tool for narrow spaces and a method for disassembling and assembling fasteners. Background technique [0002] Traditional fasteners are generally bolts with straight, cruciform, external hexagonal or internal hexagonal heads, and can be screwed with various screwdrivers or wrench tools. [0003] Fasteners for operation in narrow spaces are generally bolts with an outer hexagonal or inner hexagonal head, and are screwed with a wrench, but there are the following problems. [0004] 1. Due to the operation in a narrow space, after the wrench is rotated to a certain angle, the wrench needs to be separated from the bolt to adjust the angle of the wrench, and then screw it with the bolt. However, it is not easy to observe the operating bolt and wrench in a small space. After adjusting the angle of the wrench, it is necessar...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the operation in a narrow space, after the wrench is rotated to a certain angle, the wrench needs to be separated from the bolt to adjust the angle of the wrench, and then screw it with the bolt. However, it is not easy to observe the operating bolt and wrench in a small space. After adjusting the angle of the wrench, it is necessary to Locating the position of the bolts to cooperate with the bolts makes the operation efficiency low;

[0005] 2. During the screwing process, the wrench cannot be fixed with the bolt. Not only is it easy to slip during the operation, but also when the bolt is unscrewed or the bolt is just tightened, the bolt is easy to separate from the pre-fixed device and fall off. If it falls into the device, it will have certain Security risks;

[0006] 3. The traditional bolts can be screwed by traditional tools, which has no anti-theft effect
