[0039] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are used to illustrate the present invention and are not limited to restricting the scope of the present invention. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.
[0040] As Figure 1 , Figure 2 , Figure 6 shown, it is a structural schematic diagram of an embodiment of the present invention. A tool quick-release device is provided, which includes a mounting base 1, a guide rod mechanism 2 mounted on the mounting base 1, and a press rod guide 3 detachably connected to the guide rod mechanism 2. The mounting base 1 is fixedly connected to the execution part 100. The guide rod mechanism 2 drives the press rod guide 3 to move along the length direction of the mounting base 1, so as to press the positioning rod 101 of the execution part 100 into the positioning hole of the bacteria isolation part 300 or take out the positioning rod 101 from the positioning hole.
[0041] The mounting base 1 has a cuboid structure and is provided with a through hole along the length direction. The mounting base 1 includes a fixing part 1-1 and a mounting part 1-2. The fixing part 1-1 is provided with a fixing avoidance opening on the first side surface of the mounting base 1. The mounting base 1 is mounted on the execution part 100 through the fixing avoidance opening. The mounting seat 1-2 is provided with a mounting avoidance opening for the guide rod mechanism 2 to be placed on the second side surface of the mounting base 1. Among them, the second side surface is arranged opposite to the first side surface.
[0042] As Figure 3 shown, the guide rod mechanism 2 includes a base 2-1, a guide rod 2-2 passing through the base 2-1, a connecting rod assembly and a handle part 2-4. The base 2-1 is fixed to the mounting base 1 by a plurality of screws 6. One end of the connecting rod assembly is rotatably pin-connected to the guide rod 2-2 and the other end is rotatably pin-connected to the handle part 2-4. The handle part 2-4 is rotatably pin-connected to the base 2-1. The guide rod 2-2 can extend to the outside of the first end in the length direction of the base 2-1 under the drive of the handle assembly. An operation avoidance opening for cooperating with the connecting rod assembly and the handle part 2-4 is provided at the second end in the length direction of the base 2-1.
[0043] When the handle part 2-4 rotates away from the guide rod 2-2, the connecting rod assembly rotates and drives the guide rod 2-2 to move toward the handle part 2-4 until the guide rod 2-2 and the handle part 2-4 are in a first state of contact (such as Figure 4 When the handle part 2-4 moves toward the guide rod 2-2, the connecting rod assembly rotates and drives the guide rod 2-2 to move away from the handle part 2-4 until the connecting rod assembly is arranged along the length direction of the guide rod 2-2 in the second state (as shown in FIG. Figure 5 shown).
[0044] In order to further optimize the implementation effect of the utility model, a guide hole for the guide rod 2-2 to extend out is provided at the first end in the length direction of the base 2-1, which can guide the guide rod 2-2 and prevent it from deflecting.
[0045] In this example, the connecting rod assembly includes two connecting rods 2-3 arranged parallel to each other, and the handle component 2-4 is arranged between the two connecting rods 2-3. The arrangement of two connecting rods 2-3 can improve the stability of the structure.
[0046] The handle component 2-4 includes a connecting portion 2-4a and a handle portion 2-4b, wherein the handle portion 2-4b extends outside the base 2-1, the connecting portion 2-4a is rotatably pinned to the base 2-1 via a first pin shaft 2-5, and the connecting portion 2-4a is rotatably pinned to the connecting rod assembly via a second pin shaft 2-6. The connection points of the handle portion 2-4b and the connecting portion 2-4a, the connection points of the first pin shaft 2-5 and the connecting portion 2-4a, and the connection points of the second pin shaft 2-6 and the connecting portion 2-4a are located at the three vertices of a triangle. When the handle component 2-4 rotates, the guide rod 2-2 can be driven to move along the length direction of the mounting base 1 through the connecting rod assembly.
[0047] In this example, the guide rod 2-2 includes a guide rod portion 2-2a and a connecting rod portion 2-2b detachably connected to the guide rod portion 2-2a. The connecting rod assembly is rotatably pinned to the connecting rod portion 2-2b via a third pin shaft 2-7. The outer diameter of the connecting rod portion 2-2b is smaller than that of the guide rod portion 2-2a to facilitate rotatable connection with the two connecting rods 2-3.
[0048] In order to improve the stability of the structure, an arc-shaped support portion 2-8 matching the connecting rod 2-3 and the connecting portion 2-4a is provided in the base 2-1. When the guide rod 2-2 is in the second state, the arc-shaped support portion 2-8 can support the connecting portion 2-4a to improve the stability of the structure.
[0049] Correspondingly, both ends of the connecting rod 2-3 are arc-shaped structures, and both ends of the connecting portion 2-4a away from the handle portion 2-4b are arc-shaped structures, which can reduce interference and wear during the operation of the handle portion 2-4.
[0050] The pressure rod guide 3 includes a screw rod portion 3-1, a boss portion 3-2, and a tapered portion 3-3 arranged in sequence. The screw rod portion 3-1 is threadedly connected to the guide rod 2-2 and locked to the guide rod 2-2 by a nut 4. When the downward pressing and lifting of the handle member 2-4 are too large or too small in pressure, the length of the pressure rod guide member 3 can be adjusted until the downward pressure and lifting unlocking force of the handle member 2-4 are appropriate.
[0051] To improve the stability of the structure, a gasket 5 is provided between the nut 4 and the guide rod 2-2.
[0052] The working principle of the present utility model is as follows:
[0053] When the execution part 100 is docked to the driving part 200 equipped with the bacteria isolation part 300 and the handle member 2-4 is pressed down, the pressure rod guide 3 moves in a direction away from the handle member 2-4. A positioning groove matching the tapered portion 3-3 is provided at the end of the positioning rod 101. This positioning groove serves to position and press the execution part. The guide rod 2-2 can press the positioning rod 101 of the execution part 100 into the positioning hole of the bacteria isolation part 300 to achieve rapid and reliable positioning (as Figure 6 shown); after the operation is completed, when the handle member 2-4 is lifted, the guide rod 2-2 moves in a direction close to the handle member 2-4 and drives the positioning rod 101 to disengage from the positioning hole, realizing the unlocking of the execution part 100 (as Figure 7 shown).
[0054] In summary, the quick-release device can achieve rapid and precise positioning of the execution part and the driving part, ensure the smooth progress of the operation, and facilitate the removal of the execution part from the driving part, improving the installation and disassembly efficiency.
[0055] The above examples are only for illustrating the technical concept and characteristics of the present utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it cannot be used to limit the protection scope of the present utility model. All equivalent transformations or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
