Transversal stretching frame 4 in 1 rear end of table tenning ball servicing machine, the both ends of transversal stretching frame 4 are equipped with movable part 42 and fixed part 41, and two
The guide rod for being connected to 1 rear end of table tenning ball servicing machine is equipped between transversal stretching frame 4, guide rod is equipped with vertically reciprocal move
Dynamic adjusting block 3, the separate end of two transversal stretching framves 4 are respectively connected with vertical strut 5, positioned at two transversal stretching framves, 4 phase proximal end
Movable part 42 is hinged with adjusting block 3, is slidably connected far from the movable part 42 at end with vertical strut 5 positioned at two transversal stretching framves 4,
The fixed part 41 of two transversal stretching framves 4 is hinged with guide rod and vertical strut 5 respectively, and screen cloth is connected to 4 He of transversal stretching frame
On vertical strut 5, net collecting mechanism is followed to realize expansion and shrink.
In technical solution of the present invention, by moving up and down adjusting block 3, transversal stretching frame 4 can be driven and realize transversal stretching,
Achieve the purpose that storage and expansion net collecting mechanism, this is easy to operate；When transversal stretching frame 4 is in contraction state, vertically
Drawing close to service robot rear end for 5 high degree of strut, realizes the diminution of overall dimensions, reaches storage effect well；Simultaneously
Net collecting mechanism and table tenning ball servicing machine 1 integrally design, and are convenient for carrying.
Preferably, transversal stretching frame 4 includes the first axle and second hinge being hingedly made of several hinge bar head and the tail,
Each hinge bar in first axle is hinged with hinge bar corresponding in second hinge at middle part.The transversal stretching frame
4 can realize and largely stretch, and reliable and stable, while also achieve the support to ball screen.In mobile adjusting block 3
In the process, the angle between hinge bar changes, and changes the starting point and end of first axle and second hinge to link
The distance between, and then realize that transversal stretching frame 4 in one plane does stretching motion.
Specifically, first axle and second hinge are hingedly formed by two hinge bar head and the tail in the present embodiment.And it leads
It is U-shaped bar 2 to bar, U-shaped bar 2 is fixed on the rear end of table tenning ball servicing machine 1 in standing upside down, and the both ends of adjusting block 3 are equipped with for U-shaped
The slide opening of 2 open end of bar insertion, adjusting block 3 can be slided up and down along U-shaped bar 2.The both ends of first axle are respectively hinged at guide rod
With the bottom of vertical strut 5, one end of second hinge and adjusting block 3 are hinged, and the other end is slidably connected with vertical strut 5.Upwards
Adjusting block 3 is pulled, transversal stretching frame 4 is shunk, and realizes closing up for net collecting mechanism；Adjusting block 3 is pushed down on, transversal stretching frame 4 is stretched
It is long, realize the expansion of net collecting mechanism.
Meanwhile the top of vertical strut 5 is connected with a curved bar 6.In order to make net collecting mechanism have more preferably receipts ball effect,
6 lower end of curved bar is docked with vertical strut 5, and the upper end of curved bar 6 bends towards the middle part of ball table and extension.Curved bar 6 and vertical strut 5
It is connected by articulated structure, specifically, the lower end of curved bar 6 is equipped with upper rod set 61, and the upper end of vertical strut 5 is equipped with low stem casing
51, portion is hinged so that upper rod set 61 can be overturn in vertical plane on the outside for upper rod set 61 and low stem casing 51, upper rod set
61 and low stem casing 51 front end face on be equipped with positioning column 52, extension spring 8 is connected between positioning column 52.When needs are stored
