[0028] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1: Combination Figure 1-3 This embodiment discloses a fastening device for hardware processing, which is used to realize the fastening of tooling when drilling holes in a hardware plate a by a single person.

[0030] The fastening device for hardware processing includes a base 1, which has a main structure of a horizontal plate. The main structure in this embodiment is spliced ​​by aluminum oxide profiles. Support members 2 are connected to the bottom of the left and right sides of the base 1. The support members 2 can raise the base 1. The support members 2 in this embodiment are legs made of resin material, and the legs are detachably connected to the bottom of the base 1 by bolts.

[0031] Furthermore, the top of the base 1 is provided with a storage slot 11 for placing the hardware sheet a. The storage slot 11 is a rectangular slot structure, and its inner contour is adapted to the outer contour of the hardware sheet a to be processed, so that the hardware sheet a can be laterally limited after being placed in the storage slot 11, so that its lateral position will not move easily. In addition, the storage slot 11 is located on the front side of the base 1 and has an opening structure. The opening corner of the front side of the storage slot 11 is provided with a guide cutting angle structure, so that the hardware sheet a can enter the storage slot 11 conveniently and smoothly. It should be noted that the depth of the storage slot 11 is less than the thickness of the hardware sheet a, so that after the hardware sheet is placed in the storage slot 11, the top of the hardware sheet can be partially exposed to the outside, which is convenient for subsequent pressing and fixing.

[0032] In this embodiment, three storage slots 11 are provided on the base 1 , and the storage slots 11 are spaced apart in the transverse direction.

[0033] The base 1 is provided with holding parts 3 on the left and right sides behind the storage slot 11. The holding parts 3 are elastic strip plate structures. The holding parts 3 in this embodiment are made of aluminum alloy thin plates. The rear side end of the holding part 3 is a horizontal section, which is connected to the base 1 through a limiting bolt 4. The limiting bolt 4 is vertically arranged, and the holding part 3 is installed and fixed with a nut that acts as a cushion. The front side end of the holding part 3 is provided with an abutment portion 31 formed by bending downward. The side view profile of the abutment portion 31 is a "V"-shaped structure. The abutment portion 31 can elastically press and clamp the metal plate a placed in the storage slot 11. Combined with Figure 3 As shown, from the side view, the bottom of the abutment portion 31 presses the metal plate with a smaller contact area, and in fact, the pressing position of the pressing member 3 in the front view is a linear structure, and the pressing surface of the pressing member 3 can be flexibly selected according to actual working requirements, that is, pressing members 3 of various width specifications can be configured for backup. In other embodiments, the pressing member 3 is connected to the limiting bolt 4 by a pivot structure, and the pressing member 3 can rotate around the longitudinal center line of the limiting bolt 4, which makes it possible to flexibly adjust the angle of the pressing member 3 according to actual conditions, thereby flexibly controlling its pressing position to improve the pressing effect.

[0034] Example 2: Based on Example 1, Figure 4 As shown, in this embodiment, the holding member 3 is provided with a bending portion 32 at both sides of the front and rear of the abutting portion 31, and the bending portion 32 is bent toward the inner corner of the abutting portion 31, and the bending portion 32 presents a strip-shaped profile in the short side direction of the holding member 3. This structure makes the profile of the abutting position area of ​​the abutting portion 31 richer, and the structural changes produced by the bending portion 32 can increase the structural stability of the area, and will not be easily deformed. Therefore, the stable abutting portion 31 can improve the holding stability and extend the service life of the device components.

[0035] Embodiment 3: Based on Embodiment 2, Figure 5 As shown, the bottom of the abutting portion 31 is provided with a horizontal flat end surface 33, and the flat end surface 33 is used to abut the top of the metal plate a. Compared with the abutting structure in Example 2, the flat end surface 33 increases the pressing area, which can prevent the metal plate a from being dislocated after being pressed.

[0036] Embodiment 4: Based on Embodiment 3, Figure 6 As shown, in this embodiment, a pressing block 5 made of elastic material (rubber) is arranged on the abutting portion 31, and the bottom end of the pressing block 5 extends below the flat end surface 33. The bottom of the pressing block 5 is a horizontal end surface. By utilizing its own elasticity, it can increase the friction when contacting the metal plate a, further improving the pressing quality. It should be noted that Figure 6It is a longitudinal sectional view. When viewed from the front, the pressing block 5 is a strip-shaped structure adapted to the width of the pressing member 3.

[0037] Furthermore, a through hole 34 having a longitudinal section profile of an inverted "T"-shaped structure is provided inside the abutment portion 31, and the through hole 34 longitudinally penetrates the abutment portion 31. The longitudinal section profile of the pressure block 5 is an "I"-shaped structure and is inserted into the through hole 34. The top of the pressure block 5 has an anti-slip portion 51 extending to the top of the through hole 34, and the longitudinal section profile of the anti-slip portion 51 is a cap body structure. The anti-slip portion 51 is clamped at the top of the abutment portion 31, which enables the pressure block 5 to form a longitudinally limited clamping structure with the holding member 3 after being inserted, and has a stable connection relationship and will not fall off easily.

[0038] Furthermore, a limiting groove 52 is provided on the longitudinally fitting end surface between the pressing block 5 and the through hole 34. The limiting groove 52 is an annular groove structure when viewed from a lateral perspective. A spring 6 is provided in the limiting groove 52. The spring 6 can be extended and retracted in the longitudinal direction. The upper and lower ends of the spring 6 respectively abut against the inner walls of the through hole 34 and the limiting groove 52. The function of the spring 6 is to always apply a downward pressure to the bottom of the pressing block 5, so that the bottom of the pressing block 5 can stably extend to the bottom of the through hole 34, and also enable the pressing block 5 to have a longitudinal extension ability when pressing the hardware plate a, and have a suitable self-adjusting holding strength.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
