The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

A kind of folding stand shown in Fig. 1-4, comprises forearm 1, middle arm 2; Said forearm 1, middle arm 2 are hinged in the lower end through first hinge 5, and the upper end of forearm 1, middle arm 2 is provided with groove 3 in the junction, and said groove 3 comprises first groove 31 and second groove 32 that is positioned at arm 2 that is arranged in forearm; First groove 31 is provided with apical axis 4, the second grooves 32 and is provided with second hinge 6, and handle 7 one sides are provided with side plate 71; Handle 7 one ends are provided with two lugs 72, handle 7 horizontally set hinge axis holes, and pass two lugs 72; 72 of two lugs be provided with torsion spring 9, the second hinges 6 pass lug 72, torsion spring 9 handle 7 is connected on the arm 2, the ray pin at said torsion spring 9 two ends drops on respectively on the side plate 71 of bottom and handle 7 of groove 3; Handle 7 can be placed in the groove 3, and said handle 7 is provided with push rod 8, and push rod 8 is vertical with apical axis 4; When handle 7 tail ends when the bottom direction of first groove 31 is rotated, push rod 8 withstands on the apical axis 4, the forearm 1 of folding stand is fixed with cooperating of apical axis 4 through push rod 8 with middle arm 2.The effect of torsion spring 9 is when folding stand unclamps, and the ray pin of torsion spring 9 is upspring handle 7, and the forearm 1 that prevents vehicle frame and middle arm 2 are to fashionable, and handle 7 falls between forearm 1 and the middle arm 2 under the effect of gravity.In use, handle 7 places groove 3, is difficult for touching; Reduce the unexpected in use possibility of unclamping of vehicle frame; And the forearm 1 and the middle arm 2 of folding stand mainly receive force direction upwards, and forearm 1 is under pressure with junction, middle arm 2 upper end, so folding stand is safe in utilization, reliable.

It is the preferred version of the utility model that above-mentioned embodiment further groove 3 places the upper end of forearm 1 and arm 2, the lower end that first hinge 5 is arranged in forearm 1 and arm 2; The very convenient visual vehicle frame interlocking of user place, convenient folding, certainly; Groove 3 is arranged in the left side of forearm 1 and arm 2, the right side that first hinge 5 is arranged in forearm 1 and arm 2; Correspondingly, hinge vertically is provided with, and can realize equally.In the embodiment of epimere, for make folding after, forearm 1 and middle arm 2 certain angle that staggers; Said first hinge 5 is 5 ° to 12 ° with the trailing wheel axis L of middle arm 2 in the angle of horizontal surface inner projection, and is preferred 7 °, as shown in Figure 2; When first hinge 5 and second hinge 6 laterally arranged, handle 7 rotated along the vehicle frame folding direction, and folding stand is more reasonable; More firm during locking, as shown in Figure 6.Handle 7 sides and groove 3 inwalls are fitted, and structure is tightr, is provided with the gap between the wall of handle 7 tail ends and groove 3, and when the needs folding stand, bar handle 7 tail ends unclamp forearm 1 and middle arm 2 easily.

In the above-mentioned embodiment, apical axis 4 is located at said first groove 31, and handle 7 is located in second groove 32.In actual use, apical axis is located at said second groove, and handle is located at first groove, when the push rod on the handle and apical axis hold out against, can folding stand be locked equally.
