Examples

Referring to fig. 1, the present embodiment provides a capo 100, which includes an upper clamping member 110 and a lower clamping member 120.

As shown in fig. 1, the upper clamping member 110 includes an upper clamping arm 111 and an upper holding arm 112, and the lower clamping member 120 includes a lower clamping arm 121 and a lower holding arm 122. The upper clamp arm 111 has a first hinged end 1111 and a first free end 1112, the lower clamp arm 121 has a second hinged end 1211 and a second free end 1212, the first hinged end 1111 and the second hinged end 1211 are hinged such that the first free end 1112 can be moved closer to or farther from the second free end 1212 about the first hinged end 1111 to thereby achieve the clamping of the neck.

As shown in fig. 1 and 2, one end of the upper grip arm 112 is fixedly connected to the first hinge end 1111, and the other end extends toward one side of the lower grip arm 121, so that the upper grip arm 111 and the upper grip arm 112 form an "L" shaped structure. One end of the lower gripping arm 122 is fixedly connected to the middle of the lower clamping arm 121 and extends away from the upper clamping arm 111, so that the lower clamping arm 121 and the lower gripping arm 122 form a "T" shape. The upper holding arm 112 and the lower holding arm 122 are connected by a resilient member, which can push the lower holding arm 122 away from the upper holding arm 112. When the user needs to perform the clamping operation, the user can hold the upper holding arm 112 and the lower holding arm 122 with a hand and pinch them with a strong force, so as to separate the first free end 1112 and the second free end 1212. After the neck enters between the first free end 1112 and the second free end 1212, the upper holding arm 112 and the lower holding arm 122 are released, and the first free end 1112 and the second free end 1212 are closed to complete the clamping under the urging of the spring 130.

Further, as shown in fig. 1 and 3, a first connecting rod 113 is disposed at an end of the upper holding arm 112 away from the upper clamping arm 111, a second connecting rod 123 is disposed at an end of the lower holding arm 122 away from the lower clamping arm 121, the first connecting rod 113 has a first end 1131 and a second end 1132 which are opposite, and the second connecting rod 123 has a third end 1231 and a fourth end 1232 which are opposite. The first end portion 1131 is hinged to the upper holding arm 112, the second end portion 1132 is hinged to the third end portion 1231, the fourth end portion 1232 is hinged to the lower holding arm 122, and the second connecting rod 123 is externally slidably sleeved with the fixing sleeve 131. In the present embodiment, the cross-sections of the first connecting rod 113 and the second connecting rod 123 are rectangles having the same size, and the inner diameter of the fixing sleeve 131 is equivalent to the size of the rectangle. That is, the fixing sleeve 131 can be tightly fitted with the second connecting rod 123 when being sleeved outside the second connecting rod 123, and can realize smooth transition when sliding to the second connecting rod 123. When the first free end 1112 and the second free end 1212 are closed to complete the clamping, the first connecting rod 113 and the second connecting rod 123 are in a collinear state (i.e. an included angle between the first connecting rod 113 and the second connecting rod 123 is 180 degrees), and at this time, the fixing sleeve 131 is slid to the hinge joint of the second end 1132 and the third end 1231, so that the relative rotation between the first connecting rod 113 and the second connecting rod 123 can be limited, and the first connecting rod 113 and the second connecting rod 123 can play a role of auxiliary support.

Meanwhile, the first connecting rod 113 is annularly provided with a magnetic ring 132 made of a magnet, and the fixing sleeve 131 is made of iron or a magnet. When the first connecting rod 113 and the second connecting rod 123 are collinear, the magnetic attraction ring 132 can attract the fixing sleeve 131, so that the fixing sleeve slides to the hinge joint between the second end 1132 and the third end 1231 to complete the locking of the first connecting rod 113 and the second connecting rod 123, and the manual operation of an operator is avoided. Meanwhile, the magnetic ring 132 can provide continuous suction force to continuously fix the fixing sleeve 131, so as to prevent the sliding thereof from causing locking failure.

Further, the upper holding arm 112 is provided with a first receiving groove 114 at an end away from the upper clamping arm 111, and the first end portion 1131 is embedded in the first receiving groove 114 and hinged to a groove wall of the first receiving groove 114. The lower holding arm 122 has a second receiving groove (not shown) at an end thereof away from the lower holding arm 121, and the fourth end 1232 is embedded in the second receiving groove and hinged to a groove wall of the second receiving groove. The first receiving groove 114 and the second receiving groove are both provided to facilitate the rotation of the first connecting rod 113 and the second connecting rod 123, so that the rotation between the two is smoother.

The sum of the thicknesses of the second and

third ends

1132 and 1231 corresponds to the thickness of the second connecting rod 123. With this arrangement, when the first connecting rod 113 and the second connecting rod 123 are collinear, the thicknesses of the second end 1132 and the third end 1231 are consistent with the thickness of the second connecting rod 123, and the fixing sleeve 131 can more smoothly slide to the hinge joint of the second end 1132 and the third end 1231 to complete the locking.

The upper arm 111 is provided with a spring 133, and the spring 133 is disposed on one side of the upper arm 111 facing the lower arm 121. The elastic sheet 133 can play a role in buffering between the upper clamping arm 111 and the strings, so that the strings are prevented from being worn, and the service life of the capo 100 is prolonged.

One side of the lower clamping arm 121 facing the lower clamping arm 121 is provided with a plurality of anti-slip grooves 134, and each anti-slip groove 134 is arranged along the width direction of the lower clamping arm 121. The anti-slip grooves 134 are spaced apart along the length of the lower clamp arm 121. The anti-slip grooves 134 may serve an anti-slip function, so that the capo 100 may be more stable when clamping the neck.

In summary, the present invention provides a capo 100, which includes an upper clamping member 110 and a lower clamping member 120, wherein a first connecting rod 113 and a second connecting rod 123 are hinged to the ends of the upper clamping member 110 and the lower clamping member 120, and a fixing sleeve 131 is sleeved around the first connecting rod 113. When the first connecting rod 113 and the second connecting rod 123 are collinear, the fixing sleeve 131 can be sleeved at the hinge of the second end 1132 and the third end 1231 to limit the relative rotation between the first connecting rod 113 and the second connecting rod 123. Therefore, the auxiliary clamping effect can be achieved through the support of the first connecting rod 113 and the second connecting rod 123. On one hand, the stress of the spring 130 can be relieved, the service life of the spring 130 is prolonged, and on the other hand, the capo 100 can be clamped more stably without falling off due to collision. The capo 100 has simple structure and convenient use, increases the stability of clamping, improves the service performance of the stringed instrument and has better practical value.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
