In this embodiment, a plurality of cylinder block piece 402 is in according to even linear arrangement mode interval setting in the cylinder mounting groove 401, satisfy the three groups of different length totally 12 the fixed effect of block of spliced pole 403, not set up in the cylinder mounting groove 401 the rotatory handle of using of spiro union that has the L type can be laid in the region of cylinder block piece 402, the block arc wall has deformation intensity and is moderate, spliced pole 403 application of force can be crowded fixedly, the effect that can upwards extract of application of force, block fixed part 404 then is used for spliced pole 403 end carries out the annular magnetic attraction fixedly, makes spliced pole 403 has middle anchor ring department and presss from both sides tightly, the fixed dual fixed effect of end department annular magnetic attraction fixed, further improves spliced pole 403's laying stability avoids it to appear rocking and sends out the problem of abnormal sound.

The clamping fixing portion 404 includes an insertion block body 404a, an insertion groove 404b formed in a side surface of the insertion block body 404a, two magnet blocks 404c which are arranged on two opposite inner side surfaces of the insertion groove 404b and are magnetically attracted to each other, a pulling-up cylinder 404d which is arranged on an inner side end surface of the insertion groove 404b and is used for separating the two magnet blocks 404c to fix the magnet blocks 404c by circumferential magnetic attraction after the connection column 403 is inserted, and a pushing plate 404e which is provided with two ends on the two pulling-up cylinders 404d respectively and is used for reducing the pulling-up separation amplitude of the magnet blocks 404c by the pulling-up cylinder 404d through the inward pushing mode of the connection column 403 to increase the circumferential magnetic attraction strength of the connection column 403. The engaging and fixing portion 404 further includes a connecting string 404f provided on the magnet block 404c, a stopper post 404g provided on an inner end surface of the insertion groove 404b and adapted to fit and mount the pulling-up cylinder 404d, and a string hole 404h provided at an end of the pulling-up cylinder 404d remote from the fitting groove and adapted to pass the connecting string 404f, and the two magnet blocks 404c attract each other by magnetic force to tension the connecting string 404 f.

In this embodiment, the use method and advantages of the engaging and fixing portion 404 are as follows:

first, initially, the pushing plate 404e together with the pulling cylinder 404d is relatively close to the outside of the insertion groove 404b, the connecting string 404f passes through the string hole 404h and is largely bent at the outside end of the pulling cylinder 404d, and the two magnet pieces 404c magnetically attract each other and tension the connecting string 404f, but are separated until the connecting column 403 is inserted;

secondly, after the connecting column 403 is inserted into and pushes the pushing plate 404e, the pulling cylinder 404d moves inwards together with the pushing plate, the pulling amplitude of the connecting rope 404f is reduced, the bending degree of the connecting rope 404f is reduced and the connecting rope tends to be in a straight state, at the moment, the two magnet blocks 404c are close to each other and are finally attracted and pasted on the connecting column 403 which is iron, or the connecting column 403 which is not iron is clamped, and the connecting column 403 has an annular clamping effect at the end through the magnetic attraction effect in both modes, so that the placement stability is further improved;

third, the fixing points of the connecting string 404f on the side of the insertion groove 404b are relatively inward, and the upper and lower magnet blocks 404c are magnetically attracted to each other to tension the connecting string 404f against gravity.

The engaging and fixing portion 404 further includes a stopper 404k provided on an inner end surface of the insertion groove 404b for stopping and limiting the pushing plate 404e, an adjusting screw ring 404m screwed on an outer circumferential surface of the pulling-up cylinder 404d for adjusting the extent to which the pulling-up cylinder 404d pulls up the magnet 404c by adjusting the axial position of the pushing plate 404e with respect to the pulling-up cylinder 404d by rotation, an annular groove 404n provided on an outer circumferential surface of the adjusting screw ring 404m and having a cross section of a major arc, two connecting balls 404p provided at both ends of the pushing plate 404e for being caught on the annular groove 404n, and a jack-up spring 404q which is sleeved on the stopper post 404g and is used for jacking up the pulling-up cylinder 404d, wherein the two magnet blocks 404c and the connecting post 403 are attracted mutually by magnetic force and are separately arranged.

In this embodiment, the limiting block 404k is used for blocking the pushing plate 404e, so as to prevent the pushing plate 404e, the pulling cylinder 404d and the jacking spring 404q from being damaged by accidental impact after being pressed by a large margin, the limiting block 404k is made of soft rubber, the screw ring 404m is used for adjusting the axial position of the limiting block 404k relative to the pulling cylinder 404d, that is, when the connecting column 403 is thin, the two magnet blocks 404c need to be closer to each other to clamp the connecting column 403, or the pushing plate 404e is adjusted by rotating outwards relative to the pulling cylinder 404d, so that the connecting column 403 can push the pulling cylinder 404d inwards and lengthen the connecting rope 404f after being relatively small in width, the magnet block 404c is relatively larger in approaching width to effectively clamp the thin connecting column 403, the clamping fixing part 404 can be ensured to be capable of attracting and clamping the connecting columns 403 with different thicknesses by magnetic force.

In addition, when the connecting column 403 is thicker and has a larger distance than the two magnet blocks 404c originally, the magnet blocks 404c can be accidentally touched on the end surface of the magnet block 404c, so that the jacking spring 404q can be replaced by a larger elastic force, and the two magnet blocks 404c can be ensured to be opened by a sufficient and appropriate distance to allow the connecting column 403 to enter and then clamp the connecting column 403 by relative magnetic attraction.

The two connecting bulbs 404p on the two sides of the pushing plate 404e are respectively clamped with the two adjusting screw joint rings 404m through the annular grooves 404n, so that the two adjusting screw joint rings 404m need to be synchronously adjusted in rotation, and the pushing plate 404e is ensured to be perpendicular to the two pulling-up cylinders 404d all the time.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the appended claims.
