[0021] Please see Figures 1-7As shown in the figure, a tail pushing device for a transfer machine includes a transfer machine body 1. At one end of the transfer machine body 1, a pushing mechanism 2 is installed. The pushing mechanism 2 includes a bottom plate 201. The bottom plate 201 is welded to the bottom of one end of the transfer machine body 1. An installation plate 203 is vertically welded on the bottom plate 201.

The bottom plate 201 and the cross plate 204 are detachably connected by a connecting mechanism 3. The clamping plate 205 and the cross plate 204 are detachably connected by a clamping mechanism 4. The clamping mechanism 4 includes through holes 402. A plurality of equidistantly distributed through holes 402 are provided on the cross plate 204. Two through connecting holes 403 are provided on the clamping plate 205. One end of the clamping plate 205 is of a "concave" shape structure. One end of the clamping plate 205 is clamped with one side of the cross plate 204. Two plug pins 406 are clamped and connected on the two connecting holes 403. The plug pins 406 penetrate through the through holes 402 and extend to the outside of the other connecting hole 403. A handle 405 is connected between the tops of the two plug pins 406. Inside the bottoms of the two plug pins 406, bump blocks 407 are respectively installed. The bump blocks 407 are slidably connected with the plug pins 406 through a resisting spring 408. One end of the bump block 407 extends to the outside of the plug pin 406. One end of the bump block 407 is of a hemispherical structure. The side wall edge of one end of the bump block 407 abuts against the bottom of the clamping plate 205.
[0022] As a technical optimization scheme of the present utility model, the connecting mechanism 3 includes clamping blocks 301. A plurality of equidistantly distributed clamping blocks 301 are vertically connected to the bottom plate 201. The clamping blocks 301 are of a "convex" shape structure. A plurality of equidistantly distributed slots 304 are provided on the cross plate 204. The cross plate 204 is clamped with a plurality of bump blocks 407 through the plurality of slots 304. Through the cooperation of the bump blocks 407 and the slots 304, it is beneficial for the cross plate 204 to be detachably connected to the base.
[0023] As a technical optimization scheme of the present utility model, a limiting rod 302 is provided on the top side of the cross plate 204. The limiting rod 302 is horizontally slidably connected with the plurality of bump blocks 407. Through the installation of the limiting rod 302, it is beneficial to limit the tops of the plurality of bump blocks 407, so that the cross plate 204 and the bump blocks 407 will not slip and separate.
[0024] As a technical optimization scheme of the present utility model, cushion blocks 303 are respectively clamped and connected on the plurality of bump blocks 407. The cushion blocks 303 are of a frame structure. The bottom of the cushion blocks 303 abuts against the top of the cross plate 204. Through the installation of the cushion blocks 303, it is beneficial to abut against the cross plate 204. By installing shrinkage cushion blocks 303 with different thicknesses, it is beneficial to stably abut against the cross plate 204 with different thicknesses.
[0025] As a technical optimization of this utility model, a vertical plate 202 is vertically welded between one side of the mounting plate 203 and the base plate 201. The vertical plate 202 has a trapezoidal structure. The installation of the vertical plate 202 facilitates the reinforcement between the mounting plate 203 and the base plate 201.
[0026] As a technical optimization of this utility model, two symmetrical guide blocks 404 are installed on the card plate 205, and symmetrical guide grooves 401 are provided on both sides of the horizontal plate 204. The two guide blocks 404 are slidably connected to the two guide grooves 401. The card plate 205 is slidably connected to the horizontal plate 204 through the cooperation of the guide blocks 404 and the guide grooves 401. Through the cooperation of the guide blocks 404 and the guide grooves 401, the card plate 205 and the horizontal plate 204 can be easily slidably adjusted in position without slipping, and the operation is more convenient.
[0027] In use, this invention first welds the base plate 201 to the bottom of the transfer machine body 1. Then, the mounting plate 203 is vertically welded to the bottom to provide a shielding and positioning function. With the cooperation of the upright plate 202, the mounting plate 203 is stabilized and secure. Next, the horizontal plate 204 is connected to multiple protrusions 407. Then, the pad 303 is engaged with the multiple protrusions 407, allowing the limiting rod 302 to abut against the pad 303, reducing the range of movement of the horizontal plate 204 on the protrusions 407. Furthermore, by replacing the pads 303 with different thicknesses, it is convenient to install horizontal plates 204 of different thicknesses. Subsequently, the clamping plate 205 is engaged with the horizontal plate 204, and the guide block 404 on the clamping plate 205 is engaged with the guide groove 401 on the horizontal plate 204, allowing the clamping plate 205 to move laterally on the horizontal plate 204 to adjust its position. This ensures that the clamping plate 205 remains on the horizontal plate 204 and will not fall off, making adjustment convenient and economical. With the opening of the connecting hole 403 and the through hole 402, the insertion of two pins 406 allows the card plate 205 and the horizontal plate 204 to be detachably connected. The installation of the handle 405 facilitates the simultaneous insertion and removal of the two pins 406, making operation convenient. At the same time, removing the pins 406 facilitates the adjustment of the position of the card plate 205 and the horizontal plate 204. The cooperation of the connecting seat 206 facilitates the connection with the external hydraulic support, thereby realizing the pushing operation of the transfer machine body 1. With the cooperation of the abutment spring 408 and the protrusion 407, after the pin 406 is inserted into the connecting hole 403, the protrusion 407 quickly limits the pin 406, preventing the pin 406 from slipping off the card plate 205. By pulling the pin 406 with a certain force, the protrusion 407 breaks free from the elastic force of the abutment spring 408 and retracts, thereby allowing the pin 406 to be pulled out of the connecting hole 403.
