The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from the figures 1 to 3, the utility model comprises a U-shaped plate 1 with an upward opening, rollers 2 are arranged below the U-shaped plate 1, a plurality of blind grooves 3 are respectively arranged on the two inner side walls of the U-shaped plate 1 along the length direction at intervals, a first wedge block 4 with a wedge surface arranged in the blind grooves 3 and having a resetting trend in the blind grooves 3 is slidably arranged in each blind groove 3, a through groove 5 is respectively arranged on the two side walls of the U-shaped plate 1 along the length direction, the through groove 5 is communicated with the lower ends of the blind grooves 3 on the same side, a second wedge block 6 with a lower end extending out of the U-shaped plate 1 from the bottom of the through groove 5 and having an upward moving trend is arranged below each first wedge block 4, the wedge surface of the first wedge block 4 is contacted with the wedge surface of the second wedge block 6, the outer end surface of each second wedge block 6 is provided with a transverse groove 7 with openings at the front end and the rear end, a, the rear end of the pull rod 8 is wedge-shaped with a downward wedge surface, and the pull rod 8 can extrude the transverse groove 7 on the second wedge-shaped block 6 and enable the lower end of the second wedge-shaped block 6 to move downwards after being inserted into the through groove 5.

For the sliding of the first wedge-shaped block 4 in the blind groove 3, the upper end of the first wedge-shaped block 4 is provided with a first sliding block, the upper end face of the blind groove 3 is provided with a first sliding groove 9 for the sliding of the first sliding block, and the end of each first wedge-shaped block 4 extending out of the blind groove 3 is provided with a rubber gasket.

In order that the first wedge-shaped block 4 has a resetting trend towards the inside of the blind groove 3, two tension springs 10 are arranged in each blind groove 3, one ends of the tension springs 10 are fixed at the bottom of the blind groove 3, and the other ends of the tension springs are fixed on the first wedge-shaped block 4.

In order to realize that the second wedge-shaped block 6 has a downward movement trend, a support is installed to the lower extreme of every second wedge-shaped block 6, and every second wedge-shaped block 6 is arranged in the part cover of U-shaped plate 1 below and is equipped with a pressure spring 11, and the one end of pressure spring 11 is fixed in U-shaped plate 1 bottom, and the other end is fixed on the support, and the elastic strength of pressure spring 11 will be greater than the elastic strength of extension spring 10.

In order to realize that the pull rod 8 can slide in the through groove 5 and the pull rod 8 can drive the U-shaped plate 1 to move after being pulled out of the through groove 5, a pin 12 close to the wedge part of the pull rod 8 is arranged on the outer end face of each pull rod 8, a second sliding groove 13 capable of sliding the pin 12 is arranged on the outer side wall of each through groove 5, the front end part of the second sliding groove 13 extends out of the front end of the U-shaped plate 1, the front ends of the two pull rods 8 are fixed into a U-shaped rod structure through a connecting rod, and the U-shaped rod structure can rotate around a pin shaft after the two pull rods 8 are completely separated from the through groove 5.

The utility model discloses a concrete working process is: this device is when needs remove, insert logical inslot 5 with pull rod 8 of two, pressure spring 11 contracts naturally before inserting, the wedge of second wedge 6 extrudees the wedge of first wedge 4 this moment, make first wedge 4 have the one end of rubber pad to outwards stretch out from blind groove 3 mouths, extension spring 10 is stretched this moment, because extension spring 10's elastic strength does not have the big of pressure spring 11 far, consequently, ejecting blind groove 3 of first wedge 4 under the effect of pressure spring 11, the support bottom of wedge lower extreme is less than the lower bottom surface of gyro wheel 2 this moment, gyro wheel 2 contact ground this moment promptly, the support does not contact ground.

When the pull rod 8 is inserted into the through slot 5, the wedge parts thereof are sequentially contacted with the transverse slots 7 on the plurality of second wedge blocks 6, and the second wedge block 6 is extruded downwards under the extrusion action of the wedge part, the pressure spring 11 is stretched in the process, and the bottom of the support is gradually moved downwards and exceeds the lower end surface of the roller 2 in the process, at the moment, the roller 2 is not contacted with the ground any more, and simultaneously, in the process of moving downwards the second wedge-shaped block 6, under the reset action of the tension spring 10, the first wedge-shaped block 4 moves towards the blind groove 3, after the actions are completed, the pull rod 8 is inserted completely to logical inslot 5, and first wedge 4 retracts completely to the blind groove 3 in, and 6 supports of second wedge contact ground gyro wheel 2 then do not contact ground, put the host computer on U-shaped board 1, and U-shaped board 1 is difficult to slide by unexpected direct friction with ground when touching.

When the host computer needs to be moved, pull rod 8 is pulled out from through groove 5, and pin 12 on the pull rod is made to move to the front end of second chute 13, at the moment, the U-shaped rod can rotate around the pin shaft in second chute 13, thereby conveniently pulling U-shaped plate 1 to move, simultaneously, when pull rod 8 is pulled out, second wedge 6 is not being bound, under the reset action of pressure spring 11, second wedge 6 upwards extrudes first wedge 4, make the tip that first wedge 4 has the rubber pad stretch out, and when second wedge 6 upwards resets, make the support lower extreme upwards move, and exceed 2 lower terminal surfaces of gyro wheel gradually, 2 and ground contact of gyro wheel at this moment, first wedge 4 compresses tightly the host computer simultaneously, can effectually prevent breaking away from of host computer when pulling U-shaped plate 1.

The significant benefits of the present device: insert and extract through pull rod 8, realize stretching out and retrieving of support, realize stretching out and the withdrawal of first wedge 4 simultaneously, the effectual realization pull rod 8 pulls out when needs remove U-shaped board 1, the support withdrawal, gyro wheel 2 contacts to earth, 4 chucking host computers of first wedge simultaneously, when need not remove U-shaped board 1, pull rod 8 inserts, the support stretches out, the runner does not contact with ground, convert gyro wheel 2 into direct friction, make U-shaped board 1 remove and become the difficulty, two kinds of states switch at will, make the host computer bracket have more practical value.
