In order to solve the technical problem, the utility model provides a chin rest regulation structure of position of sitting unscrambler, it includes the shell, the shell in be equipped with the inner core, inner core and shell sliding fit, inner core and shell between be equipped with intermittent type locking mechanism, intermittent type locking mechanism including the spout that is located the inner core, the lateral wall of spout be equipped with the interval groove, the shell be equipped with the setting element that breaks away from with interval groove intermittent type nature, the setting element be located the spout.

The positioning piece comprises a clamping block and an elastic piece, the elastic piece is connected with the shell, the elastic piece is driven by external force to deform, and the elastic piece deforms to drive the clamping block to be separated from the spacing groove.

The elastic piece is a spring plate, the spring plate is suspended in the sliding groove, the clamping block is connected with the spring plate, the shell is provided with an operating hole for external force operation, and the clamping block is pressed to deform the spring plate so that the clamping block is separated from the spacing groove.

The operating hole is internally provided with a button, and the button is used for operating the clamping block by external force.

The auxiliary part is positioned in the inner core, and two sides of the open slot of the auxiliary part are provided with spaced slots which are symmetrically arranged.

After the structure above adopting, the utility model discloses compare with prior art, have following advantage:

the setting element slides in the spout, has better moving property, and the setting of interval groove also can carry out density setting as required, can have better regulation selection, and adaptability is better, and the travelling comfort of use is also better.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-5, the utility model discloses chin rest regulation structure of position of sitting unscrambler, it includes shell 1, shell 1 in be equipped with inner core 2,

inner core

2 and 1 sliding fit of shell, inner core 2 and shell 1 between be equipped with intermittent type locking mechanism, intermittent type locking mechanism including the spout 3 that is located inner core 2, the lateral wall of spout 3 be equipped with interval groove 4, shell 1 be equipped with the setting element that breaks away from with interval groove 4 intermittent type nature, the setting element be located spout 3. The casing is further strengthened with inner core complex stability to the cooperation of at first spout and setting element, further reduces rocking nature between them for whole structure is better at operation in-process stability, and secondly, the setting element freely slides in the spout can realize with the cooperation width of compartment groove, sets up the density of compartment groove as required, can guarantee the locking of casing and inner core at any time.

Specifically, the positioning element comprises a clamping block 5 and an elastic element 6, the elastic element 6 is connected with the shell 1, the elastic element 6 is driven by external force to deform, and the elastic element 6 deforms to drive the clamping block 5 to be separated from the spacing groove 4. In a normal state, the fixture block is positioned in the spacing groove, the outer shell and the inner core are in a locking state, when the adjustment is needed, the elastic piece is driven by external force to enable the fixture block to be separated from the spacing groove, after the outer shell and the inner core are adjusted, the external force is relieved, and the elastic force of the elastic piece can ensure that the fixture block is rapidly and stably matched with the spacing groove.

As a preferred scheme, the elastic member 6 is a spring plate, two symmetrical suspension platforms are arranged inside the shell, and two ends of the spring plate are mounted on the suspension platforms, so that the spring plate is suspended in the sliding groove 3, the suspension structure provides a space for deformation of the spring plate, the fixture block 5 is connected with the spring plate, in practice, the fixture block is formed by bending the middle of the spring plate and is integrated with the spring plate, of course, two independent bodies are connected together, the shell 1 is provided with an operation hole 7 for external force operation, and the fixture block 5 is pressed to deform the spring plate to separate the fixture block 5 from the spacing groove 4. The operation hole is convenient for operating the fixture block.

As a further improvement, a button 8 is arranged in the operation hole 7, and the button 8 is used for operating the fixture block 5 by external force. This is more convenient to operate.

As an improvement, the core is also provided with an auxiliary part 9 provided with an open slot, the auxiliary part 9 is positioned in the core 2, and two sides of the open slot of the auxiliary part 9 are provided with spaced slots 4 which are symmetrically arranged. The open slot also is spout partly, and this structure main objective sets up the interval groove of symmetry, and the purpose guarantees like this that the fixture block makes both sides can the atress stable to the inner core locking, increases reliability and stability, prolongs the life of whole mechanism, reinforcing practicality.
