[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3 The present application proposes a leather hole-digging jig for automobile interior, comprising a base 1, a placement groove 11 being provided on the upper side of the base 1, a pressure plate 2 being provided horizontally above the base 1, a plurality of first guide columns 3 being vertically provided on the outer periphery of the upper side of the base 1, the plurality of first guide columns 3 passing upward through the pressure plate 2, and a first limiting block 31 being provided on the top, the plurality of first guide columns 3 being slidably connected to the pressure plate 2, the plurality of first guide columns 3 being respectively sleeved with a first spring 32, the plurality of first springs 32 being located between the pressure plate 2 and the base 1, a plurality of punching assemblies 4 being provided on the lower side of the pressure plate 2 corresponding to the placement groove 11, and support blocks 5 being provided in the placement groove 11 corresponding to the punching assemblies 4;

[0020] Specifically, when punching, first place the workpiece to be punched in the placement slot 11, accurately position the workpiece through the side wall of the placement slot 11, and then press down the pressure plate 2 to dig holes in the leather of the workpiece through the punching component 4. The punching component 4 here can be set according to the position and number of holes required for the workpiece. At the same time, a support block 5 is provided to clamp the workpiece in cooperation with the punching component 4 during the punching process so that the workpiece will not move during the punching process. Compared with manual digging, the punching efficiency is greatly improved while ensuring the punching quality.

[0021] For further information, see Figure 1-2 The punching assembly 4 includes a punching head 41 vertically arranged on the lower side of the pressing plate 2, a clamping plate 42 is horizontally provided at the lower end of the punching head 41, a first clearance hole 43 is opened in the middle of the clamping plate 42 corresponding to the punching head 41, and a second guide column 44 is vertically fixed on the top of the clamping plate 42. The second guide column 44 passes through the pressing plate 2 upward and is provided with a second limit block 45 on the top. The second guide column 44 is slidably connected to the pressing plate 2, and a second spring 46 is respectively sleeved on the second guide column 44. A plurality of second springs 46 are located between the pressing plate 2 and the clamping plate;

[0022] When the pressure plate 2 is pressed down to perform the digging work, the clamping plate 42 will first abut against the surface of the workpiece, and cooperate with the support block 5 pair to clamp the workpiece to ensure that the workpiece remains stable during the drilling work and the drilling quality is guaranteed. During the continuous descending process, the clamping plate 42 will compress the second spring 46, so that the punching head 41 extends from the first clearance hole 43 to dig the workpiece. At the same time, the support block 5 is provided with a second clearance hole 51 corresponding to the punching head 41 to avoid damage to the punching head 41.

[0023] At the same time, a waste port 12 is opened at the bottom of the base 1, and the front side of the waste port 12 is connected to the outside. A third make way hole 13 connected to the second make way hole 51 is opened at the top of the waste port 12 corresponding to the second make way hole 51, so that the waste generated during punching can enter the waste port 12 from the second make way hole 51 and the third make way hole 13, which is convenient for later collection and sorting.

[0024] Another embodiment, see Figure 1 and 3 The fixture also includes a pressure rod 6. A connecting column 14 is vertically fixed to the rear side of the upper side of the base 1. The top of the connecting column 14 passes through the top of the pressure plate 2 and is slidably connected to it. The top of the connecting column 14 is hinged to one end of the pressure rod 6. A pressure block 61 is provided on the side of the pressure rod 6 facing the pressure plate 2. When the pressure rod 6 rotates clockwise along the hinge position, the pressure block 61 can abut against the pressure plate 2 to move it downward. The pressure block 61 is conical, and the end of the conical pressure block 61 is arc-shaped, which facilitates better downward pressure of the pressure block 61.

[0025] By manually rotating the pressure rod 6 clockwise along the hinge position, the pressure block 61 can be abutted against the pressure plate 2, thereby driving the punching assembly 4 to dig holes, and cooperating with the first spring 32 to reset it, the operation is more convenient and quick.
