[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1-Figure 5 A tool handle clamp comprises a support plate 1, an insertion hole 2 is arranged on the upper surface of the support plate 1, the support plate 1 is in a square shape, the insertion hole 2 is in a circular shape, the center of the insertion hole 2 is on the same axis as the center line of the support plate 1, an elastic clamping component 3 is arranged on the upper surface of the support plate 1, and the elastic clamping component 3 is used to clamp the tool handle of the tool; the clamp is placed in a through placement groove 102 on a placement plate 101 in a tool magazine, and the placement groove 102 comprises a first card groove 103 for placing the support plate 1, an empty groove 105 for accommodating the tool, and a second card groove 104 for placing the elastic clamping component 3, such as Figure 4 As shown, during installation, the four guide plates 33, the elastic plate 31, and the abutment plate 32 are inserted from the first slot at the bottom of the placement plate 1 into the four second slots 104. As the guide plates 33, the elastic plates 31, and the abutment plates 32 are inserted, the support plate 1 enters the second slot 104. When the tool is stored in the tool magazine, the tool is passed through the insertion hole 2 on the support plate 1. Through the elastic clamping assembly 3 on the support plate 1, the tool handle is fixed on the support plate 1 with the help of elastic extrusion, which is convenient for fixing the tool handle and facilitating the storage of the tool.

[0025] In this embodiment, the elastic clamping assembly 3 includes four elastic plates 31, the four elastic plates 31 are fixedly connected to the support plate 1, the four elastic plates 31 are fixed to the four sides of the support plate 1, the midlines of the four elastic plates 31 intersect with the midline of the support plate 1, the upper surfaces of the four elastic plates 31 are fixedly connected to the abutment plates 32, the abutment plates 32 are used to contact and squeeze the handle of the tool, the handle pushes the four abutment plates 32, pushes the four abutment plates 32 away, the four elastic plates 31 are tilted outward, the elastic plates 31 drive the abutment plates 32 to squeeze on the handle, and fix the handle, such as Figure 5 As shown, the tool is directly inserted when being fixed, and is fixed and restricted by elastic extrusion. When being taken out, it is directly pulled out and separated from between the multiple abutment plates 32. It is easy to use, and the structure for fixing the tool is very simple, which is convenient for subsequent maintenance and inspection.

[0026] In the present embodiment, the upper surfaces of the four abutment plates 32 are fixedly connected to the guide plates 33. The guide plates 33 are inclined outwardly. The guide plates 33 provide guidance for the knife handle so that the knife handle can accurately contact the abutment plates 32. The abutment plates 32 are used for fixing to avoid misalignment of the knife handle and the abutment plates 32. The guide plates 33 are inclined outwardly to expand the insertion range of the knife handle. As long as the tool is inserted between the range of the guide plates 33, it can slide between the abutment plates 32 under the guidance of the guide plates 33. The knife handle is squeezed and fixed from four directions by the four abutment plates 32, thereby improving fault tolerance. There is no need to aim at the middle part of the four abutment plates 32 when inserting, which is more convenient to use.

[0027] In this embodiment, all the guide plates 33 , the elastic plates 31 , and the abutting plates 32 have the same width, the length of the abutting plates 32 is half the length of the elastic plates 31 , and the length of the guide plates 33 is half the length of the abutting plates 32 .

[0028] In this embodiment, the four elastic plates 31 are inclined inwardly, the angle between the elastic plate 31 and the support plate 1 is 70°, the angle between the abutment plate 32 and the support plate 1 is 90°, the angle between the abutment plate 32 and the elastic plate 31 is 160°, and the angle between the guide plate 33 and the abutment plate 32 is 150°. There are different angles between the guide plate 33, the elastic plate 31 and the abutment plate 32, so that the shape of the guide plate 33, the elastic plate 31 and the abutment plate 32 after being connected is similar to a C-shape, in which the raised part is the abutment plate, and the C-shape opens outward, the elastic plate 31 supports the abutment plate 32 inward, and the guide plate 33 provides guidance outward, and the structure is reasonable.

[0029] In this embodiment, the guide plate 33, the elastic plate 31, the abutment plate 32 and the support plate 1 have the same thickness, the side length of the support plate 1 is three times the width of the guide plate 33, the elastic plate 31 and the abutment plate 32, the width of the guide plate 33, the elastic plate 31 and the abutment plate 32 is smaller than the side length of the support plate 1, and the four guide plates 33, the elastic plate 31 and the abutment plate 32 will not interfere with each other in four directions.

[0030] In this embodiment, the distance between the contact plate 32 and the center of the insertion hole 2 is greater than the radius of the insertion hole 2 .

[0031] In this embodiment, both sides of all the guide plates 33 are provided with arc surfaces 34 , and the arc surfaces 34 can prevent the side corners of the guide plates 33 from scratching the surface of the handle.

[0032] Working principle: the clamp is installed in the placement groove 102 on the placement plate 101, the support plate 1 is located in the first slot 103, the guide plate 33, the elastic plate 31, and the abutment plate 32 are clamped in the second slot 104, and the insertion hole 2 is aligned with the empty slot 105. When in use, the tool is inserted into the placement groove 102, the tool passes through the insertion hole 2, and the tool handle contacts the guide plate 33. As the tool handle slides down, the four abutment plates 32 are pushed open, and the four elastic plates 31 are tilted outward. The elastic plate 31 drives the abutment plate 32 to squeeze on the tool handle to fix the tool handle. When taking it out, just pull it out directly, saving time and effort.

[0033] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
