In claims of the utility model, specification and above-mentioned attached drawing, the adjacent sleeve particularly may be divided by The sleeve of another sleeve nesting and the sleeve of nested to another sleeve, i.e. the same level sleeve and secondary sleeve, the same level sleeve and Secondary sleeve be it is opposite, in addition to the sleeve of the top, remaining sleeve all can be used as the same level set after determining its nest relation Cylinder or secondary sleeve, when a certain sleeve is as secondary sleeve, opposite the same level sleeve is known as higher level's sleeve of the sleeve.

The thimble in the utility model embodiment is shown referring to Fig. 1, Fig. 1, thimble includes first sleeve 11, second sleeve 12,3rd sleeve 13, the first fastening bolt 21, the second fastening bolt 22, magnet block 6 and spring 7.

As depicted in figs. 1 and 2, the top of first sleeve 11 is equipped with thimble portion 14, and thimble portion 14 is coniform.In first set The barrel of cylinder 11 is equipped with the first scale 31 and the first groove 41, the lower end closed and upper end opening of the first groove 41.

Second sleeve 12 is equipped with tapped through hole.The barrel of second sleeve 12 is equipped with the second scale 32 and the second groove 42, the upper and lower side closing of the second groove 42.

3rd sleeve 13 is equipped with tapped through hole and recessing groove 5.The bottom of 3rd sleeve 13 is equipped with magnet block 6.

First sleeve 11 is nested in second sleeve 12 and can slide in second sleeve 12, and second sleeve 12 is nested in third Sleeve 13 can simultaneously slide in 3rd sleeve 13.First sleeve 11 and 12 clearance fit of second sleeve, second sleeve 12 and third 13 clearance fit of sleeve.

As shown in figure 3, being equipped with spring 7 between first sleeve 11 and second sleeve 12.

First fastening bolt 21 is spirally connected with the tapped through hole in second sleeve 12 and runs through second sleeve 12, the second fastening spiral shell Tapped through hole on bolt 22 and 3rd sleeve 13 is spirally connected and runs through 3rd sleeve 13.

In assembly, first second sleeve 12 is fitted into 3rd sleeve 13, reuses the second bolt 22 for second sleeve 12 It is fixed, spring 7 is packed into second sleeve 12 later, first sleeve 11 is packed into second sleeve with the state of thimble portion 14 upward After in 12, reuses the first bolt 21 and fix first sleeve 11, so far complete the assembling process of the present embodiment.

When specifically used, the circuit board printed will be needed to be placed on printing machine mounting position, a thimble is passed through into magnet Block 6 is absorbed and fixed on table of printing machine, according to circuit board idle area movable top pin position；After thimble position is fixed, adjust The first fastening bolt 21 and the second fastening bolt 22 are saved, the bottom of itself and the first groove 41 and the second groove 42 is enabled to disengage, Slide first sleeve 11 and second sleeve 12；The overhang for adjusting first sleeve 11 and second sleeve 12, makes to push up Needle portion 14 resists circuit board, and recessing groove 5 can accommodate the second fastening bolt 22, and the overhang for maximizing second sleeve 12 adjusts model It encloses；The first fastening bolt 21 and the second fastening bolt 22 are adjusted later, enable its contact in the first groove 41 and the second groove 42 Bottom fixes first sleeve 11 and the overhang of second sleeve 12, observes the first scale 31 and the second scale 32 and records phase The scale value answered.

Circuit board to be removed later, the scale value of reference record is consistent by the height adjustment of the thimble used needed for residue, Then it is arranged in circuit board idle area one by one, then circuit board is placed on printing machine mounting position, spring 7 is placed in circuit board Buffering and damping effect is provided in the process, and screen resilience can be provided after circuit board placement and thimble is returned back into predetermined altitude.Circuit Plate can carry out operation after the completion of placing.During product changes list, the thimble that will be arranged is needed to take out, according still further to above-mentioned steps Thimble is readjusted into height and is arranged on table of printing machine again, other operations can be carried out later.

Wherein, the first fastening bolt 21 can be resisted during first sleeve 11 slides up and down under the first groove 41 End avoids first sleeve 11 from being detached from second sleeve 12.First groove, 41 upper end opening allows the first fastening bolt 21 not by The limit of one groove 41 improves the adjustable range of the overhang of first sleeve 11.Second fastening bolt 22 is in second sleeve 12 The upper and lower ends that the second groove 42 can be resisted during lower slider, avoid second sleeve 12 from submerging or be detached from third set completely Cylinder 13.

The observation of scale is on the basis of higher level's sleeve top plan of sleeve where scale.If the first scale 31 is with second set Cylinder 12 top plan be benchmark line, the first scale 31 be located at reference line scale value be first sleeve 11 overhang.The The observation of two scales 32 is similarly.

In printed circuit board production when process conditions, which require to change, needs the thimble using different height, this reality The height of thimble can be adjusted by sleeve nested against one another with the thimble of novel offer.Therefore production unit only needs preset reality With the height-adjustable thimble of novel offer, the production for the circuit board that a variety of different technology conditions require can be realized, without Need to purchase again the thimbles for covering different sizes more, so that the cost of production is reduced, and the thimble due to there was only a kind of specification, Management uses upper also more convenient.

The description of description above and embodiment for explaining scope of protection of the utility model, but is not constituted to this reality With the restriction of novel protected range.By the enlightenment of the utility model or above-described embodiment, those of ordinary skill in the art are combined Common knowledge, the ordinary technical knowledge of this field and/or the prior art pass through logical analysis, reasoning or limited examination Test it is available to the modification of the utility model embodiment or in which a part of technical characteristic, equivalent replacement or other improvements, It should be included within the scope of protection of this utility model.
