Description

Portable buckling quick-mounting fastener Technical Field The invention relates to the technical field of accessories for buildings, in particular to a portable buckling quick-mounting fastener. Background The prior construction steel pipe fastener is provided with a cross right-angle fastener, a corner fastener and a butt-joint fastener, the fasteners are hinged together by a hinge shaft, the inner fastening seat and the outer fastening cover are connected by a screw rod, a nut and the like, the fastener has enough strength and durability to ensure the successful completion of engineering quality, and in addition, few fastener parts are required to facilitate quick assembly. The existing fastener connecting mode is fastened and clamped in a threaded mode, an auxiliary tool is needed to be used for operation during operation, and the existing fastener connecting mode has the defects of multiple parts, inconvenience in installation and influence on the working efficiency of a user. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a portable buckling quick-mounting fastener which is simple in structure, and when in use, a clamping hook and a rebound device are clamped only by pressing a handle, a screw is not required to be tightened, so that the working efficiency is improved, the whole fastener structure is of an integral structure, a plurality of parts are not required to be matched for use, and the portable buckling quick-mounting fastener is convenient to carry. In order to achieve the above object, the present invention is realized by the following technical scheme: the utility model provides a portable withhold fast-assembling fastener, includes the support base, and one end rotates on the support base connects handle and withhold the piece, and the handle is located and withholds the piece outside in order to drive and withhold the piece and push down, and the support base other end inboard is equipped with resilience subassembly, and resilience subassembly includes the slider with support base sliding fit, and the slider passes through spring coupling support base, is equipped with the pothook on the handle, and the handle pushes down and makes the pothook promote the slider shrink, and the pothook stretches out after the slider in order to pin the pothook. As a further implementation mode, the bracket base is U-shaped, and a pipe fitting accommodating space is formed in the middle. As a further implementation, the handle is rotatably connected with the bracket base through a first positioning pin. As a further implementation manner, the buckling piece is rotationally connected with the bracket base through a second locating pin. As a further implementation manner, a rebound piece is arranged on the periphery side of the second positioning pin to push the buckling piece to open outwards. As a further implementation mode, the rebound assembly comprises a sleeve arranged in the support base, the inner end surface of the sleeve is connected with one end of a spring, and the other end of the spring is connected with the sliding block. As a further implementation mode, the top of the front end of the sliding block is an inclined plane, and the bottom of the sliding block is provided with a clamping groove which is matched with the clamping hook. As a further implementation, the bottom surface of the end of the hook is also an inclined surface. As a further implementation, the first positioning pin is also provided with a rebound member on the circumferential side. As a further implementation, the resilient member is a return spring. The beneficial effects of the invention are as follows: 1. The fastener is simple in structure, when the fastener is used, the clamping hook and the rebound device are clamped only by pressing the handle, the screw is not required to be tightened, the working efficiency is improved, the whole fastener structure is of an integral structure, a plurality of parts are not required to be matched for use, the whole fastener is convenient to carry, the handle is used for driving the buckling piece to press downwards to be matched with the rebound device, the supporting force of the buckled pipe fitting and the rebound piece have the trend of pushing the buckling piece and the handle to be opened, the clamping hook and the rebound component are clamped, the rebound piece and the rebound device can jointly act, and the fastening effect of the fastener is further realized. 2.
