Specific embodiment

The utility model will be further described below with reference to the accompanying drawings.

Referring to as shown in Fig. 1-Fig. 7, present embodiment the technical solution adopted is that: it includes support plate 1, support tube 2, connection sheet 3；The left and right sides of about 1 two sidewalls of support plate is fixed on support tube 2 by connection sheet 3, and connection sheet 3 is bound round It is located on support tube 2, one of connection sheet 3 is fixedly connected by bolt with support plate 1, and the other side is movably arranged on support plate 1 Two sides up and down, facilitate the locking degree adjusted between connection sheet 3 and support tube 2, thus adjust support tube 2 and support plate 1 it Between pressure size；It also includes fixing seat 4, ratchet 7, spool 5, adjusting nut 8, drawstring 16, fixing axle 9, stop nut 10, limited block 11, directive wheel 13；Vertically fixed weldering is equipped with fixing seat 4 at the middle part of 1 upside of support plate, and fixing seat 4 is " door " font Setting, is welded using steel plate；The rotating middle part of fixing seat 4 is provided with spool 5, opens up on the side wall of spool 5 The through-hole 6 for having left and right to penetrate, facilitates and drawstring 16 is wound around on the lateral wall of spool；Rotation is set on the front side wall of fixing seat 4 It is equipped with ratchet 7, after the front end of spool 5 rotates through the front side wall of fixing seat 4, is fixedly connected with the middle part of ratchet 7；Fixing seat Adjusting nut 8 is provided on 4 rear wall, after the rear end of spool 5 rotates through the rear wall of fixing seat 4, with adjusting nut 8 Middle part be fixedly connected；Axis 9 is welded and fixed in fixed be equipped on the front side wall of the fixing seat 4 on 7 top of ratchet, before fixing axle 9 It holds fixing sleeve to be equipped with stop nut 10, is slidingly connected in the fixing axle 9 between stop nut 10 and the front side wall of fixing seat 4 limited Position block 11, fixed in the bottom side of limited block 11 to offer tooth socket 12, tooth socket 12 is meshed setting with ratchet 7,11 energy of limited block The rotation situation of ratchet 7 is enough controlled, it is convenient in the state of locking, prevent ratchet from inverting；The connection sheet 3 on 1 top of support plate Fixed weldering is equipped with directive wheel 13 on movable end；The left and right ends of drawstring 16 pass through the through-hole 6 at 5 middle part of spool, are wound around spiral After on axis 5, sequentially pass through directive wheel 13, the left and right sides of support plate 11 bottom of fixed frame and support plate connection sheet 3, draw The end of rope 16 is fixedly installed fixture block 14, and fixture block 14 and 3 phase of connection sheet of bottom are clamped.

Further, the top in 11 left side of limited block is fixedly installed shifting block 15, facilitates and stirs limited block 11, Facilitate operation.

Further, the drawstring 16 is wirerope, and drawstring 16 needs the pulling force that bears larger, it is therefore desirable to quality compared with High rope is drawn.

Further, the adjusting nut 8 is hexagonal socket nut, and cooperation die nut is facilitated to use.

The working principle of this specific embodiment:: by device integral installation on the support tube 2 on PCB tote cart, when need When the spacing between two neighboring support plate 1 being adjusted, at this point, drawstring 16 is in the state loosened, branch is regulated Spacing between board 1, so that support plate 1 can adapt to the size of pcb board, then staff holds die nut rotation and adjusts Save nut 8, adjusting nut 8 drives spool 5 and ratchet 7 to rotate at this time, spool 5 by the right and left of drawstring 16 slowly around It is located on spool 5, at this point, the length of drawstring 16 shortens, fixture block 14 supports the connection sheet 3 for setting 1 bottom of support plate, and drawstring 16 supports If firmly directive wheel 13, so that the pressure between connection sheet 3, support tube 2 and support plate 1 is increasing, when device entirety After locking, limited block 11 is rotated clockwise by shifting block 15, so that tooth socket 12 is meshed with ratchet 7, prevents 5 turns of spool It is dynamic, i.e., 1 entirety of support plate is locked with support tube 2.

After adopting the above structure, present embodiment has the beneficial effect that

1, the structure that the tooth socket 12 on ratchet 7 and limited block 11 used is locked, substantially increases the stabilization of device entirety Property；

2, device is in locking, it is only necessary to which a worker rotates adjusting nut 8 with die nut, i.e., adjustable four connections Pressure between piece 3 and support tube 2 reduces the investment of human resources, prevents the waste of human resources, operation is fairly simple, more It is time saving and energy saving to add.

The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope should all cover in the scope of the claims of the utility model.
