In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figure 1-7 The utility model provides a technical solution: a knife block, comprising: a back plate 1, one side of which is fixedly connected to an external mounting bracket through a connecting plate 11, and a connecting mechanism 3 is arranged on the end wall of the other side, and a knife mechanism 2 is also arranged in parallel on the front side of the back plate 1, which is rotatably connected to the connecting mechanism 3, and has: two symmetrically distributed fixed seats 21, one side of the fixed seat 21 is rotatably matched with the connecting mechanism 3 through a rotating shaft 22 arranged thereon, and a plurality of fixed rods 23 are distributed at equal angles between the two fixed seats 21, and a plurality of knife assemblies 24 are movably installed between each two adjacent fixed rods 23, and the plurality of knife assemblies 24 are arranged at equal intervals in the horizontal direction.

[0031] Specifically, the knife-turning mechanism 2 is arranged on the front side of the back plate 1, and a certain gap is reserved between the back plate 1 and the knife-turning mechanism 2, so that when the knife-turning assembly 24 on the knife-turning mechanism 2 drives the tool to rotate to the side of the back plate 1, the tool will not touch the back plate 1, causing bumps and damage to the back plate 1 and the tool.

[0032] Furthermore, the fixed seat 21 includes: a fixed block 211, a rotating shaft 22 is fixedly installed on the side wall of the fixed block 211 on one side, and multiple fixed plates 212 are fixedly installed on the outer walls around the fixed block 211. The end of each fixed plate 212 away from the fixed block 211 extends in a direction away from the fixed block 211, and multiple fixed plates 212 are distributed at equal angles around the outside of the fixed block 211, and one end of the corresponding fixed rod 23 is fixedly installed at the angle formed between each two adjacent fixed plates 212.

[0034] Specifically, the end faces of the two first clamps 242 that are close to each other, the end face of the clamping plate 246 that is away from the adjusting bolt 247, and the end faces of the two second clamps 243 that are close to each other in the present device can be freely set according to the actual shape of the tool to be clamped, so as to ensure that when the first clamp 242 (clamping plate 246) and the second clamp 243 are adjusted, the space enclosed by them can meet the requirements of clamping and fixing the tool, and no excessive restrictions are made in this scheme.

[0035] Furthermore, the adjustment mechanism 25 includes: an adjustment seat 251, in which a rotating rod 252 is rotatably connected in its inner cavity, two sliding grooves 253 communicating with its inner cavity are relatively opened on the side wall of the adjustment seat 251 away from the fixed rod 23, threaded sections 254 are provided on the outer walls of the rotating rod 252 corresponding to the two sliding grooves 253, and the thread directions of the two threaded sections 254 are opposite, a slider 255 is slidably connected in each sliding groove 253, the slider 255 and the threaded section 254 are threadedly matched, and each slider 255 is fixedly connected to the second clamping plate 243 on the side wall away from the adjustment seat 251, and both ends of the rotating rod 252 pass through the outside of the adjustment seat 251 and are fixedly connected to the knob 256.

[0036] Specifically, in other schemes, grooves are opened inward on both side walls of the adjustment seat 251, and a threaded rod is rotatably connected in the groove, and a sliding groove 253 is opened on the corresponding groove on the end surface of the adjustment seat 251 away from the fixed rod 23, and a slider 255 that is threadedly engaged with the threaded rod slides in the sliding groove 253, and a knob 256 is fixedly installed on the end of each threaded rod. When the threaded rod is controlled to rotate by the knob 256, the threaded rod drives the slider 255 to move in the sliding groove 253, so that the positions of the two second clamps 243 are adjusted separately according to actual needs to meet the use in specific usage scenarios.

[0037] Furthermore, movable grooves 244 are horizontally opened at the positions of the two second clamping plates 243 facing each other and close to the first clamping plate 242 on one side, a guide rod 245 is arranged in the movable groove 244, and a clamping plate 246 that slides with the guide rod 245 is slidably connected in the movable groove 244, an adjusting bolt 247 is screwed on the side wall of the first clamping plate 242 close to the two clamping plates 246, the threaded section of the adjusting bolt 247 is in abutment with the side wall of the clamping plate 246, and a return spring 248 is sleeved on the outer side of the guide rod 245 on the side of the clamping plate 246 away from the adjusting bolt 247.

[0039] In summary, the device can place and clamp tools of various sizes by arranging multiple tool reversing assemblies 24 on the tool reversing mechanism 2, and each tool reversing assembly 24 can control the rotation of the rotating rod 252 by rotating the knob 256. The rotating rod 252 controls the two second clamping plates 243 to move toward or away from each other through the two threaded sections 254 thereon, thereby adjusting the distance between the two, so as to adjust the longitudinal space height in the tool reversing block according to the actual tool size, and at the same time rotate the adjusting bolt 247 toward between the two first clamping plates 242, so that The adjusting bolt 247 pushes the clamping plate 246 to move toward the first clamping plate 242 on the other side, thereby shortening the distance between the clamping plate 246 and the first clamping plate 242 on the other side, so as to adjust the horizontal space width in the inverted tool block according to the actual size of the tool. Conversely, when the adjusting bolt 247 is rotated in the direction away from the two first clamping plates 242, the return spring 248 that is compressed by the force produces elastic deformation, pushing the clamping plate 246 along the movable slot 244 away from the first clamping plate 242 on the other side, thereby increasing the distance between the clamping plate 246 and the first clamping plate 242 on the other side.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
