Problems solved by technology

[0002] In modern life, the design of many furniture, decoration and mechanical equipment is becoming more and more sophisticated. During installation and maintenance, for the sake of aesthetics or structural needs, it is often necessary to install screws in small gaps. And the operating space of the handle, the work is very inconvenient or difficult to complete, which brings restrictions to the exquisite structure design. This paper proposes an extendable screw disassembly device, which can solve some problems that cannot be done by ordinary screwdrivers. And provide solutions for equipment design and maintenance

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with examples.

[0015] The components in the figure are: extension adjustment handle 1, adjustment screw 2, support wall 3, motor 4, motor fixed support 5, coupling upper plate 6, connecting rod 7, coupling middle plate 8, and coupling lower plate 9. Support plate 10, key 11, large gear 12, pinion 13 and cutter head 14.

[0016] The extensible threaded fastener dismounting device of the present invention, the three-disk six-bar coupling is designed to complete the main motion transmission, and the three discs are the upper disc 6 of the coupling, the middle disc 8 of the coupling and the lower disc of the coupling. Discs 9 are arranged in three layers in parallel, and are hinged with each other by 3 parallel connecting rods 7, which can smoothly transmit the rotation of the motor to the cutter head. The work of the cutter head, that is, the three-disk six-bar coupling connects the motor and the cut...
