[0024] Installation chassis 1: the quantity is one;

[0025] Fixed installation mechanism 4: It is arranged at the middle of the upper surface of the rear end of the installation base frame 1. The fixed installation mechanism 4 includes a reinforcing support frame 41 and a fixing bolt 42. The reinforcing support frame 41 is fixedly connected to the middle of the upper surface of the rear end of the installation base frame 1. The upper surface of the reinforcing support frame 41 is provided with a left-right symmetrical threaded connection port. The fixed installation mechanism 4 also includes a fixing bolt 42. The inside of the threaded connection port is threadedly connected with a fixing bolt 42.

[0026] Extension mechanism 5: It is arranged on the front upper surface of the mounting base 1, and the extension mechanism 5 includes a slide rail 55, which is fixedly connected to the front upper surface of the mounting base 1, and the interior of the slide rail 55 is slidably connected to the outer surface of the extended support piece 2. The extension mechanism 5 also includes a socket 51, a locking groove 52, a second fixing bolt 53 and a nut 54. The sockets 51 are all opened on the upper surface of the extended support piece 2, and the locking grooves 52 are symmetrically opened on the front upper surface of the mounting base 1. The positions of the locking grooves 52 correspond to the positions of the adjacent sockets 51 in the upper and lower directions. The interior of the sockets 51 is plugged with a second fixing bolt 53, and the lower ends of the second fixing bolts 53 are plugged into the inner side of the adjacent locking grooves 52. Then, the lower end of the second fixing bolt 53 passes through the lower surface of the locking groove 52, and the lower end of the second fixing bolt 53 is threadedly connected with a nut 54, and the upper surface of the nut 54 is in contact with the bottom surface of the extended support piece 2. Before working, the nut 54 can be unscrewed first, and then the two second fixing bolts 53 are pulled out from the inside of the socket 51, and then the extended support piece 2 is pulled to make the extended support piece 2 move forward and backward along the direction of the slide rail 5. When the extended support piece 2 slides to a suitable position, the second fixing bolt 53 is inserted into the inside formed by the socket 51 and the locking groove 52, and then the nut 54 is tightened, thereby adjusting the length of the locking piece, and the locking piece can be extended to adapt to a more complex working environment;

[0027] Among them: it also includes an extended support plate 2, which is arranged on the upper surface of the front end of the mounting base 1, the outer surface of the extended support plate 2 is slidably connected to the middle end of the extension mechanism 5, the front end of the extended support plate 2 is provided with a locking groove 3, the rear end of the extended support plate 2 is fixedly connected to the limiting plate 6, and the upper and lower surfaces of the locking groove 3 are provided with inclined grooves.

[0028] The working principle of a locking plate extension structure provided by the utility model is as follows: before work, the nut 54 can be unscrewed first, and then the two fixing bolts 53 are pulled out from the inside of the socket 51, and then the extended support plate 2 is pulled to make the extended support plate 2 move forward and backward along the direction of the slide rail 55. Until the extended support plate 2 slides to a suitable position, the fixing bolt 53 is inserted into the inside formed by the socket 51 and the locking groove 52, and then the nut 54 is tightened, thereby the length of the locking plate can be adjusted, the locking plate can be extended to adapt to a more complex working environment, and then the locking plate extension structure is installed through the fixing bolt 42. During work, the locking head generates a thrust on the front end of the extended support plate 2, and the extended support plate 2 drives the upper end of the mounting base 1 to deform, so that the extended support plate 2 tilts upward until the locking head is inserted into the locking groove 3, the deformation disappears, and the extended support plate 2 is reset. When the locking head is inserted into the locking groove 3, the forward and backward movement cannot generate an upward thrust on the extended support plate 2, and the extended support plate 2 will not be deformed. Thus, the locking plate extension structure completes the locking.
