Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: Fig. 1, 2, shown in 3, the present invention includes one and boxly draw horse stake body 1, described draw the side of horse stake body 1 be provided with a set of can the top panel mechanism 2 of up-down adjustment folding distance, the inner side horizontal of this top panel mechanism 2 have a set of can be upper and lower, successively all adjustable jack mechanism 3, and jack 31 rear end in described jack mechanism 3 is at least configured with the trapezoidal screw 32 that can hold out against jack, the front end of jack 31 can be passed to the hole 22 formed between two pieces of top boards 21 up and down in top panel mechanism 2 under the pushing tow of trapezoidal screw 32.
Described top panel mechanism 2 mainly comprises about the two pieces top boards arranged 21, top board 21 each side spin fixing with a vertically arranged screw rod 23, wherein screw rod 23 be provided with the contrary thread segment of two sections of rotation directions and be connected with the two pieces of top boards 21 arranged up and down respectively; Jack 31 in described jack mechanism 3 is fixed on vertically arranged jack stand 33, described in draw the bottom of horse stake body 1 that a jack stand guide rail 34 longitudinally arranged is installed; Described jack stand 33 is placed on described jack stand guide rail 34 and also can moves forward and backward.
Described drawing on the opposite side of arranged opposite top panel mechanism 2 on horse stake body 1 is fixed with a trapezoidal nut 35, this trapezoidal nut 35 is connected with and is placed in jack rear end and the trapezoidal screw 32 pressing close to jack, described trapezoidal screw 32 be included in adjunction on trapezoidal screw 32 to increase the external extension bar of length and to be formed a combination trapezoidal screw.
Described trapezoidal nut 35 draws the rear force bearing plate 36 on horse stake body 1 and gusset 37 to be arranged on to draw on horse stake body 1 by being fixed on, and described drawing on two pieces of top boards 21 that horse stake body 1 is settled is configured with the location-plate 24 that two pieces can prevent top board stress deformation.
