Detailed Description

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

A plug piece 3 is shown in figures 1 and 2 and comprises a protective shell 1, wherein an installation column 2 is installed in the protective shell 1, a plurality of plug pieces 3 with different specifications are connected to the installation column 2 in a rotating mode, and the thickness of the plug pieces 3 with different specifications is different. The protective shell 1 comprises a mounting shell 101 and a cover plate 102, one end of the mounting column 2 is fixedly connected in the mounting shell 101, and the cover plate 102 is provided with a rotating hole 9 for the mounting column 2 to be inserted; the mounting post 2 is fitted with the rotation hole 9 so that the cover plate 102 can rotate along the mounting post 2. The mounting shell 101 is integrally formed with a limiting column 14, and the cover plate 102 is provided with a limiting groove 15 which is in inserted connection with the limiting column 14; the restricting post 14 is engaged with the restricting groove 15 to restrict the rotational position of the cover plate 102 on the mounting case 101.

A clamping block 10 is integrally formed at the end part of the mounting column 2, a clamping groove 11 for the clamping block 10 to pass through is formed in the hole wall of the rotating hole 9, and a taking and placing groove 12 for the clamping block 10 to pass through is formed in the plug piece 3; when the cover plate 102 rotates to the position that the clamping blocks 10 are aligned with the clamping grooves 11, the cover plate 102 can be taken out of the mounting column 2, and the damaged plug piece 3 is convenient to replace. Cleaning cloth 13 is adhered to the surface of the cover plate 102 through solid glue, before the mechanical gap is measured, the cover plate 102 is rotated to insert the cover plate 102 into the gap, the cleaning cloth 13 on the cover plate 102 is used for cleaning the inner wall of the gap, and the condition that magazines adhered to the inner wall of the gap abrade the plug piece 3 is reduced.

As shown in fig. 2 and 3, the end parts of the plurality of plug sheets 3 close to the mounting column 2 are integrally formed with shifting sheets 16, and the positions of the shifting sheets 16 on different plug sheets 3 are staggered; the poking piece 16 is poked to drive the free end of the plug piece 3 to tilt, so that the plug piece 3 can be taken out more conveniently. The free ends of the plurality of plug pieces 3 are integrally formed with abutting pieces 4, and the positions of the abutting pieces 4 on different plug pieces 3 are staggered.

As shown in fig. 3 and 4, a plurality of limiting holes 5 corresponding to the abutting pieces 4 are formed in one side of the protective shell 1, which is far away from the mounting column 2, and a sliding rod 6 is connected in the limiting holes 5 in a sliding manner; one end of the sliding rod 6 facing the mounting column 2 is hinged with a limiting piece 7, and when a hinged shaft of the limiting piece 7 is positioned in the limiting hole 5, the side surface of the limiting piece 7 can abut against the side surface of the abutting piece 4; because the articulated shaft of spacing piece 7 is located spacing hole 5 for spacing piece 7 can't rotate on slide bar 6, thereby restrict the piece 4 of contacting in protective housing 1 through spacing piece 7, be about to the free end restriction of inserted sheet 3 in protective housing 1.

The distance that butt piece 4 and protective housing 1 are located between the inner wall of spacing hole 5 is greater than the width of spacing piece 7, when needs take out appointed gag bit 3, promote the slide bar 6 that corresponds with this gag bit 3, make this slide bar 6 and spacing piece 7's articulated shaft be located outside spacing hole 5, the free end of appointed gag bit 3 of retrying, thereby promote spacing piece 7 to rotate and laminate on the inner wall of protective housing 1 on slide bar 6, separate between butt piece 4 and the spacing piece 7 this moment, be convenient for take out appointed gag bit 3, and other gag bits 3 are located protective housing 1 under spacing piece 7's effect. Meanwhile, the sliding rods 6 on the protective shell 1 are also staggered, and for small-size tools such as a feeler gauge, in the process of pushing a certain sliding rod 6, the situation that other sliding rods 6 are touched to enable adjacent plug pieces 3 to be driven out of the protective shell 1 is reduced.

A reset spring 8 is sleeved on the slide bar 6, two ends of the reset spring 8 are respectively connected to the hole wall of the limiting hole 5 and the slide bar 6, and when the reset spring 8 is in a natural state, a hinged shaft of the limiting sheet 7 is positioned in the limiting hole 5; after the appointed plugging piece 3 is taken out of the protective shell 1, the sliding rod 6 is loosened to return to the initial position under the action of the reset spring 8, namely, the hinging shaft of the sliding rod 6 and the limiting piece 7 slides into the limiting hole 5, so that the operation is convenient and fast. The end face of the limiting sheet 7 is an inclined face, and the inclined face of the limiting sheet 7 faces the opening direction of the protective shell 1; when the appointed plugging piece 3 is used up, the free end of the plugging piece 3 is rotated to be accommodated in the protective shell 1, and meanwhile, the abutting piece 4 abuts against the inclined surface of the limiting piece 7 to enable the limiting piece 7 to move towards the direction of the sliding rod 6; when the abutting sheet 4 is located in the protective shell 1, the limiting sheet 7 moves towards the plug sheet 3 under the action of the return spring 8, and the side surface of the limiting sheet 7 abuts against the side surface of the abutting sheet 4, so that the purpose of limiting the plug sheet 3 in the protective shell 1 is achieved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
