Specific embodiments: referring to fig. 1-8, the utility model is a quilt fixer, comprising an upper cover 2 and a base 1 which are mutually spliced up and down, a lock core 3 is arranged between the upper cover 2 and the base 1, a groove 101 for one side of the lock core 3 to enter is arranged at the bottom of the base 1, a yielding notch 102 is arranged on the groove wall of the groove 101, one end of the yielding notch 102 extends to the groove bottom of the groove 101, the other end extends away from the groove 101 and is communicated with a mounting opening 106, an unlocking key 103 is arranged on the base 1, and the unlocking key 103 comprises:

A connection portion 1031 mounted in the mounting port 106;

the driving and pressing part 1032 and the connecting part 1031 are integrally formed and positioned in the yielding slot 102, and at least one part of the driving and pressing part 1032 extends to the outside of the base 1;

An abutting portion 1033, which is located at one end of the driving portion 1032 away from the connecting portion 1031, and one side of which abuts against an end portion of the lock cylinder 3;

the bottom of the groove 101 is provided with a lock hole for inserting a needle bar for fixing a needle, and the needle bar is inserted into the lock cylinder 3 after passing through the lock hole.

As a preferred implementation manner of this embodiment, referring to fig. 2, the abutting portion 1033 is provided with a first through hole 1034, the bottom of the groove 101 is provided with a second through hole 104, the second through hole 104 is communicated with the abdication notch 102, and the first through hole 1034 and the second through hole 104 cooperate together to form a lock hole.

In the present embodiment, the abutting portion 1033 abuts against one side of the key cylinder 3 in a slope shape. Because one side of the abutting portion 1033 is in an inclined plane shape, when the abutting portion 1033 slightly rotates along with the whole unlocking key 103, the abutting portion 1033 can better abut against and drive one side of the lock cylinder 3, and unlocking of the lock cylinder 3 is completed.

Then, the connection portion 1031 is in a plate shape, and the lower end surface of the connection portion 1031 is flush with the lower end surface of the mounting port 106.

Here, the connection portion 1031 is generally thinner, so that when the driving portion 1032 is pressed, the connection portion 1031 can be slightly deformed more easily, and since the pressing portion only needs to press the lock cylinder 3 by a slight extent to complete unlocking, the deformation degree of the connection portion 1031 is lower, and the connection portion 1031 cannot be broken in the use process.

Referring to fig. 5, to ensure that the driving portion 1032 of the unlocking key 103 is not interfered with the inner edge of the recess 102 when being pressed, a gap is left between the two sides of the unlocking key 103 and the inner edge of the recess 102.

In this embodiment, the portion of the driving portion 1032 extending outside the base 1 is provided with a pushing structure for pushing by hand. Referring to fig. 1, it can be seen that the portion of the driving and pressing portion 1032 extending out of the base 1 is square and angular, which is convenient for pressing with a finger in a larger area, and is more convenient for unlocking.

In addition, the bottom of the groove 101 extends upwards to form an annular clamping piece 105, and a notch 1051 is arranged on one side of the clamping piece 105 corresponding to the yielding notch 102.

Referring to fig. 8, the lock cylinder 3 sequentially includes, from top to bottom, a plastic cap 301, a spring 302, a rolling ball 303, a core holder 304, and a steel bowl 305, wherein an external column 3041 extending to the outside of the lock cylinder 3 is disposed at the lower end of the core holder 304, the lower end of the steel bowl 305 abuts against the clamping member 105, and the external column 3041 extends into the inner side of the clamping member 105.

In this embodiment, the lock cylinder 3 is a three-ball lock cylinder 3, and the structural principle of the three-ball lock cylinder 3 belongs to the prior art, which is not described herein.

In this embodiment, the recess 101 is located at the middle position of the base 1, and the detent 105 is located at the middle position of the recess 101.

More specifically, a downward extending and annular limiting protrusion 201 is arranged in the middle of the upper wall of the inner side of the upper cover 2, and one side of the lock cylinder 3 is placed in the limiting protrusion 201.

Here, referring to fig. 6, it can be seen that three through openings are provided on the limiting protrusion 201 at intervals, and three ribs 202 spaced from each other are provided on the outer side of the limiting protrusion 201 in a ring manner, so that the material cost can be reduced while the structural stability is ensured.

After the upper cover 2 and the base 1 are clamped with each other, the limit protrusion 201 on the upper cover 2 is matched with the clamping piece 105 on the base 1, so that the lock cylinder 3 can be firmly locked. Pressing the unlocking pressing part 1032 can slightly deform the connecting part 1031, and make the abutting part 1033 abut against the external post 3041 on the pressing lock cylinder 3 to unlock the lock cylinder 3, and at this time, the needle bar for fixing the needle can be pulled out from the lock cylinder 3 or inserted into the lock cylinder 3.

The foregoing description of a quilt holder according to the present utility model is merely a preferred embodiment of the present utility model, and is not intended to limit the scope of the present utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the present utility model.
