- Fig. 4 is described further the utility model referring to Fig.1.

One kind can connect desk, including desktop 3, be equipped with attachment device below desktop, attachment device includes telescoping mechanism 31 With fixing pipe 2, telescoping mechanism 31 is located at the side of desktop 3, and fixing pipe 2 is located at the other side of desktop 3, and telescoping mechanism 31 includes solid Determine box 1, shaft 12 and rack gear 11 are equipped in fixed bin 1, is additionally provided with driving gear 13, rack gear 11 and driving gear 13 in shaft 12 It is meshed, rack gear 11 and fixing pipe 2 are adapted；Fixed bin 1 and fixing pipe 2 are mounted on desktop 3 by screw, be easily installed and Disassembly, while it being also convenient for the transport of desktop 3, when in use, drive driving gear 13 to rotate by rotating shaft 12, to reach The purpose for keeping rack gear 11 flexible completes the fixation to adjacent desktop 3 when rack gear 11 enters to 2 suitable position of fixing pipe, because This adjacent desk forms an entirety, when one of desk is by external force, the desk can effectively be avoided to generate position It moves, to avoid the problem that influencing student's development generation because the spacing caused by desk is mobile between desk becomes smaller, simultaneously When adjacent desk links together, the phenomenon that being not in some desk protrusion, therefore classroom is cleaner and tidier, when needing to move When dynamic desk, rotating shaft 12 retracts rack gear 11 in fixed bin 1, can move to desk.

Further, fixed gear 21 is additionally provided in fixing pipe 2, fixed gear 21 and rack gear 11 are meshed, therefore work as rack gear When being meshed in 11 entrance fixing pipes 2 and with fixed gear 21, there are frictional force to prevent between fixed gear 21 and fixing pipe 2 Rack gear 11 is mobile, therefore can effectively avoid the problem that rack gear 11 because shaking the generation that falls off out of fixing pipe 2.

Further, it is equipped with teeth at left and right sides of rack gear 11, fixed gear 21 is equipped at left and right sides of rack gear 11, therefore can Effectively to be limited to rack gear 11, the shaking of rack gear 11 is avoided, while also further enhancing the fixed effect to rack gear 11 Fruit.

Further, it is additionally provided with limited block 111 on rack gear 11, the limit to match with limited block 111 is additionally provided on fixed bin 1 Slot 14；Therefore effectively rack gear 11 can be defined, avoids causing rack gear 11 from fixation because of excessive rotating shaft 12 The problem of falling off in box 1.

Further, shaft 12 is equipped with rotating handles 121；It is more saved when therefore passing through 121 rotating shaft 12 of rotating handles Power.

Further, shaft 12 is connected with fixed bin 1 by bearing 15, therefore can effectively be reduced shaft 12 and be fixed Friction between box 1 avoids the abrasion between shaft 12 and fixed bin 1, extends the service life of telescoping mechanism 31, simultaneously But also more laborsaving when rotating shaft 12.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model It protects in range.
