Description
Technical Field
The invention belongs to the technical field of communication, and relates to a wrench and a single-plate handle strip.
Background
With the development of communication technology, the requirement of communication equipment on the density of single boards is higher and higher, the requirement on the wire outlet space occupied by the structural member is more and more strict, and the slender offset wrench becomes the mainstream on the premise of meeting the use function and ensuring comfortable operation. Therefore, it is a trend to develop a wrench with more excellent functions and more comfortable use.
The prior art combines several components by sleeving sliding components and plugging springs, and completes the sliding of the components by compressing the springs.
As shown in fig. 1, a schematic diagram of a wrench in the prior art includes: the wrench comprises a wrench main body (104), a spring (103), a sliding buckling piece (101) and a screw (102). In the installation process, the spring is firstly placed into the circular hole of the sliding fastener, then the sliding fastener is placed into the square groove of the wrench body, and finally the wrench body, the spring and the sliding fastener are fixedly combined by the screw.
After the assembly is finished, the sliding buckling piece can slide left and right in the wrench main body through the gap between the wrench main body and the movable buckling piece as well as the screw and the compression of the spring. In the application of the handle strip, the existing scheme is that a rectangular hole is formed in a panel, in the process of pulling a wrench in, a sliding buckling piece slides to the tail end, the sliding buckling piece is pressed by hands, then the whole component is pressed into the rectangular hole of the panel, the sliding buckling piece is loosened, and the sliding buckling piece is returned by the restoring force of a spring. The pulling-out process of the wrench is similar to that of the prior wrench, the sliding buckling piece is withdrawn from the embedded part of the inner end face of the rectangular hole of the panel, and the whole wrench part can be pulled out.
In the process of implementing the invention, the prior art is found to have at least the following problems: the sliding among the sliding buckling piece, the screw rod and the wrench main body of the existing wrench is met through gaps, the sliding buckling piece is difficult to control in practical application, the sliding is not smooth if the sliding buckling piece is too tight, and the sliding buckling piece can shake up and down if the sliding buckling piece is too loose. The sliding buckling piece shakes up and down, so that the end face of the rectangular hole of the panel can not be buckled into the concave groove of the sliding buckling piece, the function realization is directly influenced, and meanwhile, the operation comfort is deteriorated due to too tight or too loose structure; the spring is positioned between the movable buckling piece and the screw rod, and the spring is not supported at the central line, so that the spring can shake or incline to influence the use; the wrench part is assembled by the wrench main body, the spring, the sliding buckling piece and the screw rod, the parts are various, and the assembly is relatively complex.
