Description

Arrangement tool for three-coil and half-coil string

Technical Field

The utility model relates to the field of piano assembling tools, in particular to a tool for arranging three-coil and half-coil strings.

Background

In the prior art, as shown in fig. 1, three and half turns of strings 01 need to be wound and fixed on a string shaft nail 02, and then the three and half turns of strings are arranged together tightly by a tool, so that the existing arranging tool is inconvenient to use and low in adjusting efficiency.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model aims to provide the sorting tool for the three-coil and half-coil string, which is convenient to use and high in efficiency.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a sorting tool for three-coil and half-coil strings comprises a sleeve, a connecting rod, a rocking handle, a clamp body and two handles, wherein the clamp body is provided with two symmetrically arranged and opened clamp arms, and the front ends of the two clamp arms are respectively provided with a limiting block; the two handles are connected to the clamp body in a crossed and symmetrical mode and can drive the two clamping arms to open and close; the sleeve is arranged between the two clamping arms, the rear end of the sleeve is hinged with the front end of the connecting rod, the rear end of the connecting rod is hinged with the front end of the rocking handle, and the front end of the rocking handle is hinged on the rotating shaft at the bottom of the clamp body.

Furthermore, the front ends of the two handles are hinged to the front end of one clamping arm, the middle parts of the two handles are connected with a pin shaft, and the pin shaft is connected in a sliding groove in the corresponding position of the other clamping arm in a sliding manner.

Furthermore, the upper part of the handle is provided with a U-shaped groove which is sleeved on the forceps body.

Furthermore, a protective sleeve is coated on the outer side of the lower end of the handle.

By adopting the technical scheme, when the three-ring half-coil pin is used, the sleeve is sleeved on the peg, the front end face of the sleeve abuts against the rear end face of the three-ring half-coil, meanwhile, the limiting blocks at the front ends of the two clamping arms abut against the front end face of the three-ring half-coil, the limiting blocks at the front ends of the two clamping arms are driven by the clamping handle to be close, then the tail end of the rocking handle is pressed downwards to drive the sleeve to abut against, and the three-ring half-coil is mutually close to and arranged in order under the action of pressing the front end and the rear end. Above-mentioned process can convenient and fast ground arrange in order three circles half coil on the string, and the arrangement is high-efficient reliable.

Drawings

The utility model is described in further detail below with reference to the accompanying drawings and the detailed description;

FIG. 1 is a schematic view of the upper end of a string with three and a half coils wound on a peg;

FIG. 2 is a front view of the present invention;

fig. 3 is a side view of the handle.

Detailed Description

As shown in fig. 2-3, the tool for arranging three-coil and half-coil strings of the present invention comprises a sleeve 1, a connecting rod 2, a rocking handle 3, a pincer body 4 and two handles 5, wherein the pincer body 4 has two symmetrically arranged and opened clamping arms 41, and the front ends of the two clamping arms 41 are respectively provided with a limiting block 42; the two handles 5 are connected to the pincer body 4 in a crossed and symmetrical manner and can drive the two clamping arms 41 to open and close; the sleeve 1 is arranged between the two clamping arms 41, the rear end of the sleeve 1 is hinged with the front end of the connecting rod 2, the rear end of the connecting rod 2 is hinged with the front end of the rocking handle 3, and the front end of the rocking handle 3 is hinged on a rotating shaft 43 at the bottom of the clamp body 4.

As a connection mode, the front ends of the two handles 5 are hinged to the front end of one clamping arm 41, the middle parts of the two handles 5 are connected with a pin shaft 51, and the pin shaft 51 is slidably connected in the sliding groove 42 at the corresponding position of the other clamping arm 41. By adopting the structure, the lower parts of the two handles 5 can be clamped to drive the two clamping arms to mutually lean against each other.

The upper portion of handle 5 has U type groove 52, and U type groove 52 cup joints on the pincers body 4, and the design connection is more reliable like this, and sleeve pipe 1 supports on two handles 5 simultaneously, the phenomenon of "bowing" can not appear.

The outer side of the lower end of the handle 5 is coated with a protective sleeve (not shown in the figure), so that the injury of hands of a human body in the process of exerting force can be avoided.

During the use, cup joint sleeve pipe 1 on the peg nail and the preceding terminal surface of sleeve pipe 1 withstands the rear end face of three rings of half coils, simultaneously, the stopper 42 of two arm lock 41 front ends withstands the preceding terminal surface of three rings of half coils, press from both sides tight handle 5 and drive the stopper 42 of two arm lock 41 front ends and lean on tightly, then push down the end of rocking handle 3 (adjust the degree that rocking handle 3 pushed down according to actual need), drive sleeve pipe 1 and push up forward, three rings of half coils are under the effect of pushing up in the front, draw close each other and neatly arrange. Above-mentioned process can convenient and fast ground arrange in order three circles half coil on the string, and the arrangement is high-efficient reliable.

While the utility model has been described in connection with the above embodiments, it is to be understood that the utility model is not limited to the disclosed embodiments, which are illustrative and not restrictive, and that those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
