The piano tuning spanner is one of the instrument that needs to use among the piano tuning process, traditional piano tuning spanner is the L type, by the handle, the connecting rod, connecting seat and connector constitute, the handle is installed to the top screw thread of connecting rod, the connecting seat is installed to the bottom screw thread of connecting rod, be provided with the connecting hole that is certain angle on the connecting seat, the connecting hole internal thread is installed and is used for the connector with the string button joint, because the type of piano is different, such as upright piano, grand piano etc., under the normal conditions, for making things convenient for the piano tuning and avoiding damaging the piano, or avoid the handle to touch with baffle or other string buttons, require the angle between connecting rod and the connector to be greater than 90, therefore, when tuning different types of piano, need change different connecting seats, not only the process is loaded down with trivial details, also increased the acquisition cost because of the connecting seat that needs to prepare a plurality of different angles, therefore, it is necessary to improve it.
Disclosure of Invention
The utility model aims to provide a: the utility model provides a simple structure, convenient to use, at the piano tuning in-process, can adjust the angle between connector and the connecting rod, solve the present not only process of changing different connecting seats loaded down with trivial details, also increased the piano tuning spanner that can the angle modulation who purchases the cost problem.
The technical scheme of the utility model is that:
a piano tuning spanner capable of adjusting angles comprises a handle, a connecting rod, a connecting seat and a connecting head, wherein the handle is installed on the top of the connecting rod in a threaded manner, and the connecting seat is installed on the bottom of the connecting rod in a threaded manner; the method is characterized in that: the connecting seat consists of a connecting sleeve and a mounting seat, and the connecting sleeve is in threaded connection with the connecting rod; the bottom of the connecting sleeve is movably provided with a mounting seat through symmetrically arranged ear plates and an assembly pin shaft, a groove is axially arranged on a connecting rod above the connecting seat, an adjusting part is embedded in the groove in a sliding manner, an external thread is arranged on the connecting rod corresponding to the groove, an adjusting nut is arranged on the connecting rod through the external thread, and the adjusting nut and the adjusting part are mutually clamped; the adjusting piece is movably connected with the mounting base through an adjusting rod and a pin shaft.
The adjusting piece is U-shaped.
The adjusting rod is Y-shaped.
As an improvement, a scale value is axially arranged on the connecting rod on one side of the groove, so that the angle between the mounting seat and the connecting rod can be conveniently adjusted.
The beneficial effects of the utility model reside in that:
this piano tuning spanner that can angle modulation passes through positive and negative rotation adjusting nut, can drive the regulating part and go upward or down in the recess, and the regulating part drives the mount pad through adjusting the pole and uses assembly pin axle to rotate as the axle center to realize the angular adjustment between mount pad and the connecting rod, and then the adaptation is to different types of piano tuning, it is loaded down with trivial details not only to have solved the current connecting seat of changing difference process, has also increased the problem of acquisition cost, the specially adapted piano tuning spanner of special use piano
And (5) tuning for use.
Drawings
FIG. 1 is a schematic view of the present invention;
FIG. 2 is an enlarged schematic view of FIG. 1 at A;
fig. 3 is a schematic sectional view taken along line a-a in fig. 2.
In the figure: 1. the device comprises a handle, 2, a connecting rod, 3, a connector, 4, a connecting sleeve, 5, a mounting seat, 6, an ear plate, 7, an assembly pin shaft, 8, an adjusting piece, 9, an adjusting nut, 10 and an adjusting rod; 11. and (4) a groove.
Detailed Description
This piano tuning spanner that can angle modulation comprises handle 1, connecting rod 2, connecting seat and connector 3, and handle 1 is installed to the top screw thread of connecting rod 2, and the connecting seat is installed to the bottom screw thread of connecting rod 2. The connecting seat is composed of a connecting sleeve 4 and a mounting seat 5, and the connecting sleeve 4 is in threaded connection with the connecting rod 2; the bottom of connecting sleeve 4 has mount pad 5 through otic placode 6 and the movable mounting of assembly pin 7 that the symmetry set up, and connector 3 is installed to the end screw thread of mount pad 5, and connector 3 is the tube-shape body of hexagon socket head, through clamping of connector 3 and string button to and change the piano string button of the adaptable different specifications of connector 3 and carry out the tuning.
A groove 11 is axially arranged on the connecting rod 2 above the connecting seat, a U-shaped adjusting part 8 is embedded in the groove 11 in a sliding mode, an external thread is arranged on the connecting rod 2 corresponding to the groove, an adjusting nut 9 is arranged on the connecting rod 2 through the external thread, and the adjusting part 8 is U-shaped and is located in the adjusting nut 9; the adjusting nut 9 is arranged behind the groove 11 of the connecting rod 2; the adjusting nut 9 and the adjusting part 8 are mutually clamped; the adjusting nut 9 and the adjusting part 8 can slide in the circumferential direction, the adjusting part 8 can move up and down along the groove 11 along with the positive and negative rotation of the adjusting nut 9, and the bottom of the adjusting part 8 is movably connected with the mounting seat 5 through a Y-shaped adjusting rod 10 and a pin shaft.
